    9p: virtio: fix unlikely null pointer deref in handle_rerror
    
    [ Upstream commit 13ade4ac5c28e8a014fa85278f5a4270b215f906 ]
    
    handle_rerror can dereference the pages pointer, but it is not
    necessarily set for small payloads.
    In practice these should be filtered out by the size check, but
    might as well double-check explicitly.
    
    This fixes the following scan-build warnings:
    net/9p/trans_virtio.c:401:24: warning: Dereference of null pointer [core.NullDereference]
                    memcpy_from_page(to, *pages++, offs, n);
                                         ^~~~~~~~

    9p: virtio: make sure 'offs' is initialized in zc_request
    
    [ Upstream commit 4a73edab69d3a6623f03817fe950a2d9585f80e4 ]
    
    Similarly to the previous patch: offs can be used in handle_rerrors
    without initializing on small payloads; in this case handle_rerrors will
    not use it because of the size check, but it doesn't hurt to make sure
    it is zero to please scan-build.
    
    This fixes the following warning:
    net/9p/trans_virtio.c:539:3: warning: 3rd function call argument is an uninitialized value [core.CallAndMessage]
                    handle_rerror(req, in_hdr_len, offs, in_pages);

    This adjusts whitespace as well as less code will now be included

    [ Upstream commit 3c6b1212d20bbbffcad5709ab0f2d5ed9b5859a8 ]
    
    When code uses a pre-increment it makes the reader question "why".
    In the constraint fetching code there is no reason for the variables
    to be pre-incremented so adjust to post-increment.
    No intended functional changes.

    ALSA: ac97: Fix possible error value of *rac97
    
    [ Upstream commit 67de40c9df94037769967ba28c7d951afb45b7fb ]
    
    Before committing 79597c8bf64c, *rac97 always be NULL if there is
    an error. When error happens, make sure *rac97 is NULL is safer.
    
    For examble, in snd_vortex_mixer():
            err = snd_ac97_mixer(pbus, &ac97, &vortex->codec);
            vortex->isquad = ((vortex->codec == NULL) ?
                    0 : (vortex->codec->ext_id&0x80));
    If error happened but vortex->codec isn't NULL, this may cause some
    problems.
    
    Move the judgement order to be clearer and better.

    ALSA: hda/cirrus: Fix broken audio on hardware with two CS42L42 codecs.
    
    commit 99bf5b0baac941176a6a3d5cef7705b29808de34 upstream.
    
    Recently in v6.3-rc1 there was a change affecting behaviour of hrtimers
    (commit 0c52310f260014d95c1310364379772cb74cf82d) and causing
    few issues on platforms with two CS42L42 codecs. Canonical/Dell
    has reported an issue with Vostro-3910.
    We need to increase this value by 15ms.

    ALSA: pcm: Fix missing fixup call in compat hw_refine ioctl
    
    commit 358040e3807754944dbddf948a23c6d914297ed7 upstream.
    
    The update of rate_num/den and msbits were factored out to
    fixup_unreferenced_params() function to be called explicitly after the
    hw_refine or hw_params procedure.  It's called from
    snd_pcm_hw_refine_user(), but it's forgotten in the PCM compat ioctl.
    This ended up with the incomplete rate_num/den and msbits parameters
    when 32bit compat ioctl is used.
    
    This patch adds the missing call in snd_pcm_ioctl_hw_params_compat().

ALSA: usb-audio: Add quirk for Microsoft Modern Wireless Headset [+ + +]

    ALSA: usb-audio: Add quirk for Microsoft Modern Wireless Headset
    
    [ Upstream commit 3da435063777f8d861ba5a165344e3f75f839357 ]
    
    Microsoft Modern Wireless Headset (appearing on the host as "Microsoft
    USB Link") has a playback and a capture mixer volume/switch, but they
    are fairly broken.  The descriptor reports wrong dB ranges for
    playback, and the capture volume/switch don't influence on the actual
    recording at all.  Moreover, there seem instabilities in the
    connection, and at best, we should disable the runtime PM.
    
    So this ended up with a quirk entry for:
    - Correct the playback dB range;
      I picked up some reasonable values but it's a guess work
    - Disable the capture mixer;
      it's completely useless and confuses PA/PW
    - Suppress get-sample-rate, apply the delay for message handling,
      and suppress the auto-suspend
    
    The behavior of the wheel control on the headset is somehow flaky,
    too, but it's an issue of HID.

arm64/fpsimd: Only provide the length to cpufeature for xCR registers [+ + +]

Date:   Mon Jul 31 14:58:48 2023 +0100

    arm64/fpsimd: Only provide the length to cpufeature for xCR registers
    
    [ Upstream commit 01948b09edc3fecf8486c57c2d2fb8b80886f3d0 ]
    
    For both SVE and SME we abuse the generic register field comparison
    support in the cpufeature code as part of our detection of unsupported
    variations in the vector lengths available to PEs, reporting the maximum
    vector lengths via ZCR_EL1.LEN and SMCR_EL1.LEN.  Since these are
    configuration registers rather than identification registers the
    assumptions the cpufeature code makes about how unknown bitfields behave
    are invalid, leading to warnings when SME features like FA64 are enabled
    and we hotplug a CPU:
    
      CPU features: SANITY CHECK: Unexpected variation in SYS_SMCR_EL1. Boot CPU: 0x0000000000000f, CPU3: 0x0000008000000f
      CPU features: Unsupported CPU feature variation detected.
    
    SVE has no controls other than the vector length so is not yet impacted
    but the same issue will apply there if any are defined.
    
    Since the only field we are interested in having the cpufeature code
    handle is the length field and we use a custom read function to obtain
    the value we can avoid these warnings by filtering out all other bits
    when we return the register value, if we're doing that we don't need to
    bother reading the register at all and can simply use the RDVL/RDSVL
    value we were filling in instead.

    arm64: dts: qcom: apq8016-sbc: Fix ov5640 regulator supply names
    
    [ Upstream commit 43a684580819e7f35b6cb38236be63c4cba26ef4 ]
    
    The ov5640 driver expects DOVDD, AVDD and DVDD as regulator supply names.
    
    The ov5640 has depended on these names since the driver was committed
    upstream in 2017. Similarly apq8016-sbc.dtsi has had completely different
    regulator names since its own initial commit in 2020.
    
    Perhaps the regulators were left on in previous 410c bootloaders. In any
    case today on 6.5 we won't switch on the ov5640 without correctly naming
    the regulators.

    arm64: dts: qcom: sm8250-edo: Add GPIO line names for PMIC GPIOs
    
    [ Upstream commit 6b8a63350752c6a5e4b54f2de6174084652cd3cd ]
    
    Sony ever so graciously provides GPIO line names in their downstream
    kernel (though sometimes they are not 100% accurate and you can judge
    that by simply looking at them and with what drivers they are used).
    
    Add these to the PDX203&206 DTSIs to better document the hardware.
    
    Diff between 203 and 206:
    pm8009_gpios
    <                         "CAM_PWR_LD_EN",
    >                         "NC",

    >                         "NC", /* GPIO_10 */
    Which is due to 5 II having an additional Google Assistant hardware
    button and 1 II having a wireless charger & different camera wiring
    to accommodate the additional 3D iToF sensor.

    Which makes sense, as 203 has a 3D iToF, slightly different camera
    power wiring and WLC (WireLess Charging).

    arm64: dts: qcom: sm8250: correct dynamic power coefficients
    
    [ Upstream commit 775a5283c25d160b2a1359018c447bc518096547 ]
    
    sm8250 faces the same problem with its Energy Model as sdm845. The energy
    cost of LITTLE cores is reported to be higher than medium or big cores
    
    EM computes the energy with formula:
    
    energy = OPP's cost / maximum cpu capacity * utilization
    
    On v6.4-rc6 we have:
    max capacity of CPU0 = 284
    capacity of CPU0's OPP(1612800 Hz) = 253
    cost of CPU0's OPP(1612800 Hz) = 191704
    
    max capacity of CPU4 = 871
    capacity of CPU4's OPP(710400 Hz) = 255
    cost of CPU4's OPP(710400 Hz) = 343217
    
    Both OPPs have almost the same compute capacity but the estimated energy
    per unit of utilization will be estimated to:
    
    energy CPU0 = 191704 / 284 * 1 = 675
    energy CPU4 = 343217 / 871 * 1 = 394
    
    EM estimates that little CPU0 will consume 71% more than medium CPU4 for
    the same compute capacity. According to [1], little consumes 25% less than
    medium core for Coremark benchmark at those OPPs for the same duration.
    
    Set the dynamic-power-coefficient of CPU0-3 to 105 to fix the energy model
    for little CPUs.

    arm64: sdei: abort running SDEI handlers during crash
    
    commit 5cd474e57368f0957c343bb21e309cf82826b1ef upstream.
    
    Interrupts are blocked in SDEI context, per the SDEI spec: "The client
    interrupts cannot preempt the event handler." If we crashed in the SDEI
    handler-running context (as with ACPI's AGDI) then we need to clean up the
    SDEI state before proceeding to the crash kernel so that the crash kernel
    can have working interrupts.
    
    Track the active SDEI handler per-cpu so that we can COMPLETE_AND_RESUME
    the handler, discarding the interrupted context.

    After commit 71de0a054d0e ("arm64: tegra: Drop serial clock-names and

    Commit 71de0a054d0e ("arm64: tegra: Drop serial clock-names and

    ARM: dts: BCM53573: Fix Ethernet info for Luxul devices
    
    [ Upstream commit 44ad8207806973f4e4f7d870fff36cc01f494250 ]
    
    Both Luxul's XAP devices (XAP-810 and XAP-1440) are access points that
    use a non-default design. They don't include switch but have a single
    Ethernet port and BCM54210E PHY connected to the Ethernet controller's
    MDIO bus.
    
    Support for those devices regressed due to two changes:
    
    1. Describing MDIO bus with switch
    After commit 9fb90ae6cae7 ("ARM: dts: BCM53573: Describe on-SoC BCM53125
    rev 4 switch") Linux stopped probing for MDIO devices.
    
    2. Dropping hardcoded BCM54210E delays
    In commit fea7fda7f50a ("net: phy: broadcom: Fix RGMII delays
    configuration for BCM54210E") support for other PHY modes was added but
    that requires a proper "phy-mode" value in DT.
    
    Both above changes are correct (they don't need to be reverted or
    anything) but they need this fix for DT data to be correct and for Linux
    to work properly.

    Use STM32 ADC generic bindings instead of legacy bindings on
    emtrion GmbH Argon boards.
    
    The STM32 ADC specific binding to declare channels has been deprecated,
    hence adopt the generic IIO channels bindings, instead.
    The STM32MP151 device tree now exposes internal channels using the
    generic binding. This makes the change mandatory here to avoid a mixed
    use of legacy and generic binding, which is not supported by the driver.

    ARM: OMAP2+: Fix -Warray-bounds warning in _pwrdm_state_switch()
    
    commit 847fb80cc01a54bc827b02547bb8743bdb59ddab upstream.
    
    If function pwrdm_read_prev_pwrst() returns -EINVAL, we will end
    up accessing array pwrdm->state_counter through negative index
    -22. This is wrong and the compiler is legitimately warning us
    about this potential problem.
    
    Fix this by sanity checking the value stored in variable _prev_
    before accessing array pwrdm->state_counter.
    
    Address the following -Warray-bounds warning:
    arch/arm/mach-omap2/powerdomain.c:178:45: warning: array subscript -22 is below array bounds of 'unsigned int[4]' [-Warray-bounds]

    and "syscall_faked" have been broken. Both seccomp and PTRACE depend
    on using the special value of "-1" for skipping syscalls. This value
    wasn't working because it was getting masked by __NR_SYSCALL_MASK in
    both PTRACE_SET_SYSCALL and get_syscall_nr().
    
    Explicitly test for -1 in PTRACE_SET_SYSCALL and get_syscall_nr(),
    leaving it exposed when present, allowing tracers to skip syscalls
    again.

    In converting to using the standard u16_fract type, commit [1] made the
    obvious mistake and failed to take account of the difference in
    numerator and denominator ordering, breaking all uses of the cs43130
    codec.
    
    Fix it.

ASoC: da7219: Check for failure reading AAD IRQ events [+ + +]

    ASoC: da7219: Check for failure reading AAD IRQ events
    
    [ Upstream commit f0691dc16206f21b13c464434366e2cd632b8ed7 ]
    
    When handling an AAD interrupt, if IRQ events read failed (for example,
    due to i2c "Transfer while suspended" failure, i.e. when attempting to
    read it while DA7219 is suspended, which may happen due to a spurious
    AAD interrupt), the events array contains garbage uninitialized values.
    So instead of trying to interprete those values and doing any actions
    based on them (potentially resulting in misbehavior, e.g. reporting
    bogus events), refuse to handle the interrupt.

ASoC: da7219: Flush pending AAD IRQ when suspending [+ + +]
Author: Dmytro Maluka <[email protected]>

    ASoC: da7219: Flush pending AAD IRQ when suspending
    
    [ Upstream commit 91e292917dad64ab8d1d5ca2ab3069ad9dac6f72 ]
    
    da7219_aad_suspend() disables jack detection, which should prevent
    generating new interrupts by DA7219 while suspended. However, there is a
    theoretical possibility that there is a pending interrupt generated just
    before suspending DA7219 and not handled yet, so the IRQ handler may
    still run after DA7219 is suspended. To prevent that, wait until the
    pending IRQ handling is done.
    
    This patch arose as an attempt to fix the following I2C failure
    occurring sometimes during system suspend or resume:
    
    [  355.876211] i2c_designware i2c_designware.3: Transfer while suspended

    which indicates that the AAD IRQ handler is unexpectedly running when
    DA7219 is suspended, and as a result, is trying to read data from DA7219
    over I2C and is hitting the I2C driver "Transfer while suspended"
    failure.
    
    However, with this patch the above failure is still reproducible. So
    this patch does not fix any real observed issue so far, but at least is
    useful for confirming that the above issue is not caused by a pending
    IRQ but rather looks like a DA7219 hardware issue with an IRQ
    unexpectedly generated after jack detection is already disabled.

block/mq-deadline: use correct way to throttling write requests [+ + +]
Author: Zhiguo Niu <[email protected]>
Date:   Thu Aug 3 19:12:42 2023 +0800

    block/mq-deadline: use correct way to throttling write requests
    
    [ Upstream commit d47f9717e5cfd0dd8c0ba2ecfa47c38d140f1bb6 ]
    
    The original formula was inaccurate:
    dd->async_depth = max(1UL, 3 * q->nr_requests / 4);
    
    For write requests, when we assign a tags from sched_tags,
    data->shallow_depth will be passed to sbitmap_find_bit,
    see the following code:
    
    nr = sbitmap_find_bit_in_word(&sb->map[index],
                            min_t (unsigned int,
                            __map_depth(sb, index),
                            depth),
                            alloc_hint, wrap);
    
    The smaller of data->shallow_depth and __map_depth(sb, index)
    will be used as the maximum range when allocating bits.
    
    For a mmc device (one hw queue, deadline I/O scheduler):
    q->nr_requests = sched_tags = 128, so according to the previous
    calculation method, dd->async_depth = data->shallow_depth = 96,
    and the platform is 64bits with 8 cpus, sched_tags.bitmap_tags.sb.shift=5,
    sb.maps[]=32/32/32/32, 32 is smaller than 96, whether it is a read or
    a write I/O, tags can be allocated to the maximum range each time,

    [ Upstream commit 7ebe4eda4265642859507d1b3ca330d8c196cfe5 ]
    
    In the last step of the EEH recovery process, the EEH driver calls into
    bnx2x_io_resume() to re-initialize the NIC hardware via the function
    bnx2x_nic_load().  If an error occurs during bnx2x_nic_load(), OS and
    hardware resources are released and an error code is returned to the
    caller.  When called from bnx2x_io_resume(), the return code is ignored
    and the network interface is brought up unconditionally.  Later attempts
    to send a packet via this interface result in a page fault due to a null
    pointer reference.
    
    This patch checks the return code of bnx2x_nic_load(), prints an error
    message if necessary, and does not enable the interface.

bpf: Fix an error in verifying a field in a union [+ + +]
Author: Yafang Shao <[email protected]>
Date:   Thu Jul 13 02:56:41 2023 +0000

    bpf: Fix an error in verifying a field in a union
    
    [ Upstream commit 33937607efa050d9e237e0c4ac4ada02d961c466 ]
    
    We are utilizing BPF LSM to monitor BPF operations within our container
    environment. When we add support for raw_tracepoint, it hits below
    error.
    
    ; (const void *)attr->raw_tracepoint.name);
    27: (79) r3 = *(u64 *)(r2 +0)
    access beyond the end of member map_type (mend:4) in struct (anon) with off 0 size 8
    
    It can be reproduced with below BPF prog.
    
    SEC("lsm/bpf")
    int BPF_PROG(bpf_audit, int cmd, union bpf_attr *attr, unsigned int size)
    {
            switch (cmd) {
            case BPF_RAW_TRACEPOINT_OPEN:
                    bpf_printk("raw_tracepoint is %s", attr->raw_tracepoint.name);
                    break;
            default:
                    break;
            }
            return 0;
    }
    
    The reason is that when accessing a field in a union, such as bpf_attr,
    if the field is located within a nested struct that is not the first
    member of the union, it can result in incorrect field verification.
    
      union bpf_attr {
          struct {
              __u32 map_type; <<<< Actually it will find that field.
              __u32 key_size;
              __u32 value_size;
             ...
          };
          ...
          struct {
              __u64 name;    <<<< We want to verify this field.
              __u32 prog_fd;
          } raw_tracepoint;
      };
    
    Considering the potential deep nesting levels, finding a perfect
    solution to address this issue has proven challenging. Therefore, I
    propose a solution where we simply skip the verification process if the
    field in question is located within a union.

    bpf: Fix issue in verifying allow_ptr_leaks
    
    commit d75e30dddf73449bc2d10bb8e2f1a2c446bc67a2 upstream.
    
    After we converted the capabilities of our networking-bpf program from
    cap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf program
    failed to start. Because it failed the bpf verifier, and the error log
    is "R3 pointer comparison prohibited".
    
    A simple reproducer as follows,
    
    SEC("cls-ingress")
    int ingress(struct __sk_buff *skb)
    {
            struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr);
    
            if ((long)(iph + 1) > (long)skb->data_end)
                    return TC_ACT_STOLEN;
            return TC_ACT_OK;
    }
    
    Per discussion with Yonghong and Alexei [1], comparison of two packet
    pointers is not a pointer leak. This patch fixes it.
    
    Our local kernel is 6.1.y and we expect this fix to be backported to
    6.1.y, so stable is CCed.

bpf: reject unhashed sockets in bpf_sk_assign [+ + +]
Author: Lorenz Bauer <[email protected]>
Date:   Thu Jul 20 17:30:06 2023 +0200

    bpf: reject unhashed sockets in bpf_sk_assign
    
    [ Upstream commit 67312adc96b5a585970d03b62412847afe2c6b01 ]
    
    The semantics for bpf_sk_assign are as follows:
    
        sk = some_lookup_func()
        bpf_sk_assign(skb, sk)
        bpf_sk_release(sk)
    
    That is, the sk is not consumed by bpf_sk_assign. The function
    therefore needs to make sure that sk lives long enough to be
    consumed from __inet_lookup_skb. The path through the stack for a
    TCPv4 packet is roughly:
    
      netif_receive_skb_core: takes RCU read lock
        __netif_receive_skb_core:
          sch_handle_ingress:
            tcf_classify:
              bpf_sk_assign()
          deliver_ptype_list_skb:
            deliver_skb:
              ip_packet_type->func == ip_rcv:
                ip_rcv_core:
                ip_rcv_finish_core:
                  dst_input:
                    ip_local_deliver:
                      ip_local_deliver_finish:
                        ip_protocol_deliver_rcu:
                          tcp_v4_rcv:
                            __inet_lookup_skb:
                              skb_steal_sock
    
    The existing helper takes advantage of the fact that everything
    happens in the same RCU critical section: for sockets with
    SOCK_RCU_FREE set bpf_sk_assign never takes a reference.
    skb_steal_sock then checks SOCK_RCU_FREE again and does sock_put
    if necessary.
    
    This approach assumes that SOCK_RCU_FREE is never set on a sk
    between bpf_sk_assign and skb_steal_sock, but this invariant is
    violated by unhashed UDP sockets. A new UDP socket is created
    in TCP_CLOSE state but without SOCK_RCU_FREE set. That flag is only
    added in udp_lib_get_port() which happens when a socket is bound.
    
    When bpf_sk_assign was added it wasn't possible to access unhashed
    UDP sockets from BPF, so this wasn't a problem. This changed
    in commit 0c48eefae712 ("sock_map: Lift socket state restriction
    for datagram sockets"), but the helper wasn't adjusted accordingly.
    The following sequence of events will therefore lead to a refcount
    leak:
    
    1. Add socket(AF_INET, SOCK_DGRAM) to a sockmap.
    2. Pull socket out of sockmap and bpf_sk_assign it. Since
       SOCK_RCU_FREE is not set we increment the refcount.
    3. bind() or connect() the socket, setting SOCK_RCU_FREE.
    4. skb_steal_sock will now set refcounted = false due to
       SOCK_RCU_FREE.
    5. tcp_v4_rcv() skips sock_put().
    
    Fix the problem by rejecting unhashed sockets in bpf_sk_assign().
    This matches the behaviour of __inet_lookup_skb which is ultimately
    the goal of bpf_sk_assign().

    correctly on hosts where vmlinux.h does not define
    BPF_LINK_TYPE_PERF_EVENT (running kernel versions lower than 5.15, for

    clk: imx: composite-8m: fix clock pauses when set_rate would be a no-op
    
    [ Upstream commit 4dd432d985ef258e3bc436e568fba4b987b59171 ]
    
    Reconfiguring the clock divider to the exact same value is observed
    on an i.MX8MN to often cause a longer than usual clock pause, probably
    because the divider restarts counting whenever the register is rewritten.
    
    This issue doesn't show up normally, because the clock framework will
    take care to not call set_rate when the clock rate is the same.
    However, when we reconfigure an upstream clock, the common code will
    call set_rate with the newly calculated rate on all children, e.g.:
    
      - sai5 is running normally and divides Audio PLL out by 16.
      - Audio PLL rate is increased by 32Hz (glitch-free kdiv change)
      - rates for children are recalculated and rates are set recursively
      - imx8m_clk_composite_divider_set_rate(sai5) is called with
        32/16 = 2Hz more
      - imx8m_clk_composite_divider_set_rate computes same divider as before
      - divider register is written, so it restarts counting from zero and
        MCLK is briefly paused, so instead of e.g. 40ns, MCLK is low for 120ns.
    
    Some external clock consumers can be upset by such unexpected clock pauses,
    so let's make sure we only rewrite the divider value when the value to be
    written is actually different.

clk: Mark a fwnode as initialized when using CLK_OF_DECLARE() macro [+ + +]
Author: Saravana Kannan <[email protected]>
Date:   Wed Mar 1 17:46:38 2023 -0800

    clk: Mark a fwnode as initialized when using CLK_OF_DECLARE() macro
    
    commit c28cd1f3433c7e339315d1ddacaeacf0fdfbe252 upstream.
    
    We already mark fwnodes as initialized when they are registered as clock
    providers. We do this so that fw_devlink can tell when a clock driver
    doesn't use the driver core framework to probe/initialize its device.
    This ensures fw_devlink doesn't block the consumers of such a clock
    provider indefinitely.
    
    However, some users of CLK_OF_DECLARE() macros don't use the same node
    that matches the macro as the node for the clock provider, but they
    initialize the entire node. To cover these cases, also mark the nodes
    that match the macros as initialized when the init callback function is
    called.
    
    An example of this is "stericsson,u8500-clks" that's handled using
    CLK_OF_DECLARE() and looks something like this:
    
    clocks {
            compatible = "stericsson,u8500-clks";
    
            prcmu_clk: prcmu-clock {
                    #clock-cells = <1>;
            };
    
            prcc_pclk: prcc-periph-clock {
                    #clock-cells = <2>;

                    #reset-cells = <2>;
            };
            ...
    };
    
    This patch makes sure that "clocks" is marked as initialized so that
    fw_devlink knows that all nodes under it have been initialized. If the
    driver creates struct devices for some of the subnodes, fw_devlink is
    smart enough to know to wait for those devices to probe, so no special
    handling is required for those cases.

    the operation, "nr_pages << PAGE_SHIFT", in coresight tmc driver, will
    overflow when nr_pages >= 0x80000(correspond to 1G AUX buffer). The
    overflow cause buffer allocation to fail, and TMC driver will alloc
    minimal buffer size(1M). You can just get about 2M perf data(1M AUX
    buffer + perf data header) at least.

cpu/hotplug: Prevent self deadlock on CPU hot-unplug [+ + +]

    cpu/hotplug: Prevent self deadlock on CPU hot-unplug
    
    commit 2b8272ff4a70b866106ae13c36be7ecbef5d5da2 upstream.
    
    Xiongfeng reported and debugged a self deadlock of the task which initiates
    and controls a CPU hot-unplug operation vs. the CFS bandwidth timer.
    
        CPU1                                                 CPU2
    
    T1 sets cfs_quota
       starts hrtimer cfs_bandwidth 'period_timer'
    T1 is migrated to CPU2
                                                    T1 initiates offlining of CPU1
    Hotplug operation starts
      ...
    'period_timer' expires and is re-enqueued on CPU1
      ...
    take_cpu_down()
      CPU1 shuts down and does not handle timers
      anymore. They have to be migrated in the
      post dead hotplug steps by the control task.
    
                                                    T1 runs the post dead offline operation
                                                    T1 is scheduled out
                                                    T1 waits for 'period_timer' to expire
    
    T1 waits there forever if it is scheduled out before it can execute the hrtimer
    offline callback hrtimers_dead_cpu().
    
    Cure this by delegating the hotplug control operation to a worker thread on
    an online CPU. This takes the initiating user space task, which might be
    affected by the bandwidth timer, completely out of the picture.

cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver [+ + +]

Date:   Fri Aug 18 11:44:52 2023 +0000

    cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver
    
    [ Upstream commit 60dd283804479c4a52f995b713f448e2cd65b8c8 ]
    
    After loading the amd-pstate-ut driver, amd_pstate_ut_check_perf()
    and amd_pstate_ut_check_freq() use cpufreq_cpu_get() to get the policy
    of the CPU and mark it as busy.
    
    In these functions, cpufreq_cpu_put() should be used to release the
    policy, but it is not, so any other entity trying to access the policy
    is blocked indefinitely.
    
    One such scenario is when amd_pstate mode is changed, leading to the
    following splat:
    
    [ 1332.103727] INFO: task bash:2929 blocked for more than 120 seconds.

    cpufreq: amd-pstate-ut: Remove module parameter access
    
    [ Upstream commit 8d6e5e8268e89979d86501dbb8385ce2e6154de1 ]
    
    In amd-pstate-ut, shared memory-based systems call
    get_shared_mem() as part of amd_pstate_ut_check_enabled()
    function. This function was written when CONFIG_X86_AMD_PSTATE
    was tristate config and amd_pstate can be built as a module.
    
    Currently CONFIG_X86_AMD_PSTATE is a boolean config and module
    parameter shared_mem is removed. But amd-pstate-ut code still
    accesses this module parameter. Remove those accesses.

    cpufreq: brcmstb-avs-cpufreq: Fix -Warray-bounds bug
    
    commit e520d0b6be950ce3738cf4b9bd3b392be818f1dc upstream.
    
    Allocate extra space for terminating element at:
    
    drivers/cpufreq/brcmstb-avs-cpufreq.c:
    449         table[i].frequency = CPUFREQ_TABLE_END;
    
    and add code comment to make this clear.
    
    This fixes the following -Warray-bounds warning seen after building
    ARM with multi_v7_defconfig (GCC 13):
    In function 'brcm_avs_get_freq_table',
        inlined from 'brcm_avs_cpufreq_init' at drivers/cpufreq/brcmstb-avs-cpufreq.c:623:15:

cpufreq: Fix the race condition while updating the transition_task of policy [+ + +]
Author: Liao Chang <[email protected]>
Date:   Tue Aug 29 07:03:18 2023 +0000

    cpufreq: Fix the race condition while updating the transition_task of policy
    
    [ Upstream commit 61bfbf7951ba561dcbdd5357702d3cbc2d447812 ]
    
    The field 'transition_task' of policy structure is used to track the
    task which is performing the frequency transition. Using this field to
    print a warning once detect a case where the same task is calling
    _begin() again before completing the preivous frequency transition via
    the _end().
    
    However, there is a potential race condition in _end() and _begin() APIs
    while updating the field 'transition_task' of policy, the scenario is
    depicted below:
    
                 Task A                            Task B
    
            /* 1st freq transition */
            Invoke _begin() {
                    ...
                    ...
            }
                                            /* 2nd freq transition */
                                            Invoke _begin() {
                                                    ... //waiting for A to
                                                    ... //clear
                                                    ... //transition_ongoing
                                                    ... //in _end() for
                                                    ... //the 1st transition
                                                            |
            Change the frequency                            |
                                                            |
            Invoke _end() {                                 |
                    ...                                     |
                    ...                                     |
                    transition_ongoing = false;             V
                                                    transition_ongoing = true;
                                                    transition_task = current;
                    transition_task = NULL;
                    ... //A overwrites the task
                    ... //performing the transition
                    ... //result in error warning.
            }
    
    To fix this race condition, the transition_lock of policy structure is
    now acquired before updating policy structure in _end() API. Which ensure
    that only one task can update the 'transition_task' field at a time.

cpufreq: intel_pstate: set stale CPU frequency to minimum [+ + +]

Date:   Sun Aug 20 13:46:49 2023 -0700

    cpufreq: intel_pstate: set stale CPU frequency to minimum
    
    commit d51847acb018d83186e4af67bc93f9a00a8644f7 upstream.
    
    The intel_pstate CPU frequency scaling driver does not
    use policy->cur and it is 0.
    When the CPU frequency is outdated arch_freq_get_on_cpu()
    will default to the nominal clock frequency when its call to
    cpufreq_quick_getpolicy_cur returns the never updated 0.
    Thus, the listed frequency might be outside of currently
    set limits. Some users are complaining about the high
    reported frequency, albeit stale, when their system is
    idle and/or it is above the reduced maximum they have set.
    
    This patch will maintain policy_cur for the intel_pstate
    driver at the current minimum CPU frequency.

    [ Upstream commit aec48805163338f8413118796c1dd035661b9140 ]
    
    If pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, this
    means the clk wasn't prepared and enabled. Returning early in this case
    however is wrong as then the following resource frees are skipped and this
    is never catched up. So do all the cleanups but clk_disable_unprepare().
    
    Also don't emit a warning, as stm32_hash_runtime_resume() already emitted
    one.
    
    Note that the return value of stm32_hash_remove() is mostly ignored by
    the device core. The only effect of returning zero instead of an error
    value is to suppress another warning in platform_remove(). So return 0
    even if pm_runtime_resume_and_get() failed.

    [ Upstream commit 597d0ec0e4ca6a912affea4cc94df08959e9ec74 ]
    
    MAC (CGX or RPM) asserts backpressure at TL3 or TL2 node of the egress
    hierarchical scheduler tree depending on link level config done. If
    there are multiple PFC priorities enabled at a time and for all such
    flows to backoff, each priority will have to assert backpressure at
    different TL3/TL2 scheduler nodes and these flows will need to submit
    egress pkts to these nodes.
    
    Current PFC configuration has an issue where in only one backpressure
    scheduler node is being allocated which is resulting in only one PFC
    priority to work. This patch fixes this issue.

    There was a previous attempt to fix an out-of-bounds access in the DCCP
    error handlers, but that fix assumed that the error handlers only want
    to access the first 8 bytes of the DCCP header. Actually, they also look
    at the DCCP sequence number, which is stored beyond 8 bytes, so an
    explicit pskb_may_pull() is required.

    dlm: fix plock lookup when using multiple lockspaces
    
    commit 7c53e847ff5e97f033fdd31f71949807633d506b upstream.
    
    All posix lock ops, for all lockspaces (gfs2 file systems) are
    sent to userspace (dlm_controld) through a single misc device.
    The dlm_controld daemon reads the ops from the misc device
    and sends them to other cluster nodes using separate, per-lockspace
    cluster api communication channels.  The ops for a single lockspace
    are ordered at this level, so that the results are received in
    the same sequence that the requests were sent.  When the results
    are sent back to the kernel via the misc device, they are again
    funneled through the single misc device for all lockspaces.  When
    the dlm code in the kernel processes the results from the misc
    device, these results will be returned in the same sequence that
    the requests were sent, on a per-lockspace basis.  A recent change
    in this request/reply matching code missed the "per-lockspace"
    check (fsid comparison) when matching request and reply, so replies
    could be incorrectly matched to requests from other lockspaces.

    [ Upstream commit 50c5e6f41d5ad7c731c31135a30d0e4f0e4fea26 ]
    
    Kernel PASID and user PASID are separately enabled. User needs to know the
    user PASID enabling status to decide how to use IDXD device in user space.
    This is done via the attribute /sys/bus/dsa/devices/dsa0/pasid_enabled.
    It's unnecessary for user to know the kernel PASID enabling status because
    user won't use the kernel PASID. But instead of showing the user PASID
    enabling status, the attribute shows the kernel PASID enabling status. Fix
    the issue by showing the user PASID enabling status in the attribute.

drivers: base: Free devm resources when unregistering a device [+ + +]

    drivers: base: Free devm resources when unregistering a device
    
    [ Upstream commit 699fb50d99039a50e7494de644f96c889279aca3 ]
    
    In the current code, devres_release_all() only gets called if the device
    has a bus and has been probed.
    
    This leads to issues when using bus-less or driver-less devices where
    the device might never get freed if a managed resource holds a reference
    to the device. This is happening in the DRM framework for example.
    
    We should thus call devres_release_all() in the device_del() function to
    make sure that the device-managed actions are properly executed when the
    device is unregistered, even if it has neither a bus nor a driver.
    
    This is effectively the same change than commit 2f8d16a996da ("devres:
    release resources on device_del()") that got reverted by commit
    a525a3ddeaca ("driver core: free devres in device_release") over
    memory leaks concerns.
    
    This patch effectively combines the two commits mentioned above to
    release the resources both on device_del() and device_release() and get
    the best of both worlds.

Drivers: hv: vmbus: Don't dereference ACPI root object handle [+ + +]
Author: Maciej S. Szmigiero <[email protected]>
Date:   Wed Aug 9 20:40:18 2023 +0200

    Drivers: hv: vmbus: Don't dereference ACPI root object handle
    
    [ Upstream commit 78e04bbff849b51b56f5925b1945db2c6e128b61 ]
    
    Since the commit referenced in the Fixes: tag below the VMBus client driver
    is walking the ACPI namespace up from the VMBus ACPI device to the ACPI
    namespace root object trying to find Hyper-V MMIO ranges.
    
    However, if it is not able to find them it ends trying to walk resources of
    the ACPI namespace root object itself.
    This object has all-ones handle, which causes a NULL pointer dereference
    in the ACPI code (from dereferencing this pointer with an offset).
    
    This in turn causes an oops on boot with VMBus host implementations that do
    not provide Hyper-V MMIO ranges in their VMBus ACPI device or its
    ancestors.
    The QEMU VMBus implementation is an example of such implementation.
    
    I guess providing these ranges is optional, since all tested Windows
    versions seem to be able to use VMBus devices without them.
    
    Fix this by explicitly terminating the lookup at the ACPI namespace root
    object.
    
    Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interface
    by default - they only do so if the KVM PV interface is missing or
    disabled.

    async flipping isn't supported if a plane's framebuffer changes memory
    domains during an atomic commit. So, move the check from
    dm_crtc_helper_atomic_check() to amdgpu_dm_atomic_check() and check if
    the memory domain has changed in amdgpu_dm_atomic_check().

    drm/amdgpu: avoid integer overflow warning in amdgpu_device_resize_fb_bar()
    
    [ Upstream commit 822130b5e8834ab30ad410cf19a582e5014b9a85 ]
    
    On 32-bit architectures comparing a resource against a value larger than
    U32_MAX can cause a warning:
    
    drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1344:18: error: result of comparison of constant 4294967296 with expression of type 'resource_size_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]

                        ~~~~~~~~~~ ^ ~~~~~~~~~~~~~~
    
    As gcc does not warn about this in dead code, add an IS_ENABLED() check at
    the start of the function. This will always return success but not actually resize
    the BAR on 32-bit architectures without high memory, which is exactly what
    we want here, as the driver can fall back to bank switching the VRAM
    access.

    drm/amdgpu: Match against exact bootloader status
    
    [ Upstream commit d3de41ee5febe5c2d9989fe9810bce2bb54a3a8e ]
    
    On PSP v13.x ASICs, boot loader will set only the MSB to 1 and clear the
    least significant bits for any command submission. Hence match against
    the exact register value, otherwise a register value of all 0xFFs also
    could falsely indicate that boot loader is ready. Also, from PSP v13.0.6
    and newer, bits[7:0] will be used to indicate command error status.

    [ Upstream commit ce7d88110b9ed5f33fe79ea6d4ed049fb0e57bce ]
    
    Don't assume that only the driver would be accessing LNKCTL. ASPM policy
    changes can trigger write to LNKCTL outside of driver's control.  And in
    the case of upstream bridge, the driver does not even own the device it's
    changing the registers for.
    
    Use RMW capability accessors which do proper locking to avoid losing
    concurrent updates to the register value.

drm/radeon: Use RMW accessors for changing LNKCTL [+ + +]

    drm/radeon: Use RMW accessors for changing LNKCTL
    
    [ Upstream commit 7189576e8a829130192b33c5b64e8a475369c776 ]
    
    Don't assume that only the driver would be accessing LNKCTL. ASPM policy
    changes can trigger write to LNKCTL outside of driver's control.  And in
    the case of upstream bridge, the driver does not even own the device it's
    changing the registers for.
    
    Use RMW capability accessors which do proper locking to avoid losing
    concurrent updates to the register value.

    [ Upstream commit ce53ad81ed36c24aff075f94474adecfabfcf239 ]
    
    Current igen6_edac checks for pending errors before the registration
    of the error handler. However, there is a possibility that the error
    occurs during the registration process, leading to unhandled pending

    repeatedly injecting errors during the loading of the igen6_edac.
    
    Fix this issue by moving the pending error handler after the registration
    of the error handler, ensuring that no pending errors are left unhandled.

eventfd: prevent underflow for eventfd semaphores [+ + +]

    eventfd: prevent underflow for eventfd semaphores
    
    [ Upstream commit 758b492047816a3158d027e9fca660bc5bcf20bf ]
    
    For eventfd with flag EFD_SEMAPHORE, when its ctx->count is 0, calling
    eventfd_ctx_do_read will cause ctx->count to overflow to ULLONG_MAX.
    
    An underflow can happen with EFD_SEMAPHORE eventfds in at least the
    following three subsystems:
    
    (1) virt/kvm/eventfd.c
    (2) drivers/vfio/virqfd.c
    (3) drivers/virt/acrn/irqfd.c
    
    where (2) and (3) are just modeled after (1). An eventfd must be
    specified for use with the KVM_IRQFD ioctl(). This can also be an
    EFD_SEMAPHORE eventfd. When the eventfd count is zero or has been
    decremented to zero an underflow can be triggered when the irqfd is shut
    down by raising the KVM_IRQFD_FLAG_DEASSIGN flag in the KVM_IRQFD
    ioctl():
    
            // ctx->count == 0
            kvm_vm_ioctl()
            -> kvm_irqfd()
               -> kvm_irqfd_deassign()
                  -> irqfd_deactivate()
                     -> irqfd_shutdown()
                        -> eventfd_ctx_remove_wait_queue(&cnt)
                           -> eventfd_ctx_do_read(&cnt)
    
    Userspace polling on the eventfd wouldn't notice the underflow because 1
    is always returned as the value from eventfd_read() while ctx->count
    would've underflowed. It's not a huge deal because this should only be
    happening when the irqfd is shutdown but we should still fix it and
    avoid the spurious wakeup.

ext4: fix unttached inode after power cut with orphan file feature enabled [+ + +]

Date:   Wed Jun 28 21:20:11 2023 +0800

    ext4: fix unttached inode after power cut with orphan file feature enabled
    
    [ Upstream commit 1524773425ae8113b0b782886366e68656b34e53 ]
    
    Running generic/475(filesystem consistent tests after power cut) could
    easily trigger unattached inode error while doing fsck:
      Unattached zero-length inode 39405.  Clear? no
    
      Unattached inode 39405
      Connect to /lost+found? no
    
    Above inconsistence is caused by following process:
           P1                       P2
    ext4_create
     inode = ext4_new_inode_start_handle  // itable records nlink=1
     ext4_add_nondir
       err = ext4_add_entry  // ENOSPC
        ext4_append
         ext4_bread
          ext4_getblk
           ext4_map_blocks // returns ENOSPC
       drop_nlink(inode) // won't be updated into disk inode
       ext4_orphan_add(handle, inode)
        ext4_orphan_file_add
     ext4_journal_stop(handle)
                          jbd2_journal_commit_transaction // commit success
                  >> power cut <<
    ext4_fill_super
     ext4_load_and_init_journal   // itable records nlink=1
     ext4_orphan_cleanup
      ext4_process_orphan
       if (inode->i_nlink)        // true, inode won't be deleted
    
    Then, allocated inode will be reserved on disk and corresponds to no
    dentries, so e2fsck reports 'unattached inode' problem.
    
    The problem won't happen if orphan file feature is disabled, because
    ext4_orphan_add() will update disk inode in orphan list mode. There
    are several places not updating disk inode while putting inode into
    orphan area, such as ext4_add_nondir(), ext4_symlink() and whiteout
    in ext4_rename(). Fix it by updating inode into disk in all error
    branches of these places.

    and is simpler since the option is normally enabled anyway.

    firmware: cs_dsp: Fix new control name check
    
    [ Upstream commit 7ac1102b227b36550452b663fd39ab1c09378a95 ]
    
    Before adding a new FW control, its name is checked against
    existing controls list. But the string length in strncmp used
    to compare controls names is taken from the list, so if beginnings
    of the controls are matching,  then the new control is not created.
    For example, if CAL_R control already exists, CAL_R_SELECTED
    is not created.
    The fix is to compare string lengths as well.

    If an fsverity builtin signature is given for a file but the

    HID: input: Support devices sending Eraser without Invert
    
    [ Upstream commit 276e14e6c3993317257e1787e93b7166fbc30905 ]
    
    Some digitizers (notably XP-Pen Artist 24) do not report the Invert
    usage when erasing.  This causes the device to be permanently stuck with
    the BTN_TOOL_RUBBER tool after sending Eraser, as Invert is the only
    usage that can release the tool.  In this state, Touch and Inrange are
    no longer reported to userspace, rendering the pen unusable.
    
    Prior to commit 87562fcd1342 ("HID: input: remove the need for
    HID_QUIRK_INVERT"), BTN_TOOL_RUBBER was never set and Eraser events were
    simply translated into BTN_TOUCH without causing an inconsistent state.
    
    Introduce HID_QUIRK_NOINVERT for such digitizers and detect them during
    hidinput_configure_usage().  This quirk causes the tool to be released
    as soon as Eraser is reported as not set.  Set BTN_TOOL_RUBBER in
    input->keybit when mapping Eraser.

    [ Upstream commit 039980de89dc9dd757418d6f296e4126cc3f86c3 ]
    
    The nomadik driver uses devres to register itself with the hwrng core,
    the driver will be unregistered from hwrng when its device goes out of
    scope. This happens after the driver's remove function is called.
    
    However, nomadik's clock is disabled in the remove function. There's a
    short timeframe where nomadik is still registered with the hwrng core
    although its clock is disabled. I suppose the clock must be active to
    access the hardware and serve requests from the hwrng core.
    
    Switch to devm_clk_get_enabled and let devres disable the clock and
    unregister the hwrng. This avoids the race condition.

    i3c: master: svc: fix probe failure when no i3c device exist
    
    commit 6e13d6528be2f7e801af63c8153b87293f25d736 upstream.
    
    I3C masters are expected to support hot-join. This means at initialization
    time we might not yet discover any device and this should not be treated
    as a fatal error.
    
    During the DAA procedure which happens at probe time, if no device has
    joined, all CCC will be NACKed (from a bus perspective). This leads to an
    early return with an error code which fails the probe of the master.
    
    Let's avoid this by just telling the core through an I3C_ERROR_M2
    return command code that no device was discovered, which is a valid
    situation. This way the master will no longer bail out and fail to probe
    for a wrong reason.

    When issuing a sync via ice_ptp_exec_tmr_cmd(), the hardware will
    simultaneously apply the commands programmed for the main timer and each
    PHY port. Neither the main timer command register, nor the PHY port command
    registers auto clear on command execution.
    
    During the execution of a timer command intended for a single port on E822
    devices, such as those used to configure a PHY during link up, the driver
    is not correctly clearing the previous commands.
    
    This results in unintentionally executing the last programmed command on
    the main timer and other PHY ports whenever performing reconfiguration on
    E822 ports after link up. This results in unintended side effects on other
    timers, depending on what command was previously programmed.
    
    To fix this, the driver must ensure that the main timer and all other PHY
    ports are properly initialized to perform no action.
    
    The enumeration for timer commands does not include an enumeration value
    for doing nothing. Introduce ICE_PTP_NOP for this purpose. When writing a
    timer command to hardware, leave the command bits set to zero which
    indicates that no operation should be performed on that port.
    
    Modify ice_ptp_one_port_cmd() to always initialize all ports. For all ports
    other than the one being configured, write their timer command register to
    ICE_PTP_NOP. This ensures that no side effect happens on the timer command.
    
    To fix this for the PHY ports, modify ice_ptp_one_port_cmd() to always
    initialize all other ports to ICE_PTP_NOP. This ensures that no side
    effects happen on the other ports.
    
    Call ice_ptp_src_cmd() with a command value if ICE_PTP_NOP in
    ice_sync_phy_timer_e822() and ice_start_phy_timer_e822().
    
    With both of these changes, the driver should no longer execute a stale
    command on the main timer or another PHY port when reconfiguring one of the
    PHY ports after link up.

    On s390 systems (aka mainframes), it has classic channel devices for
    networking and permanent storage that are currently even more common
    than PCI devices. Hence it could have a fully functional s390 kernel

    [including ioremap(), devm_ioremap(), etc.] are not available.
    
    Here let FSL_EDMA and INTEL_IDMA64 depend on HAS_IOMEM so that it
    won't be built to cause below compiling error if PCI is unset.

    Input: i8042 - add quirk for TUXEDO Gemini 17 Gen1/Clevo PD70PN
    
    commit eb09074bdb05ffd6bfe77f8b4a41b76ef78c997b upstream.
    
    The touchpad of this device is both connected via PS/2 and i2c. This causes
    strange behavior when both driver fight for control. The easy fix is to
    prevent the PS/2 driver from accessing the mouse port as the full feature
    set of the touchpad is only supported in the i2c interface anyway.
    
    The strange behavior in this case is, that when an external screen is
    connected and the notebook is closed, the pointer on the external screen is
    moving to the lower right corner. When the notebook is opened again, this
    movement stops, but the touchpad clicks are unresponsive afterwards until
    reboot.

    [ Upstream commit 534103bcd52ca9c1fecbc70e717b4a538dc4ded8 ]
    
    When unbinding pasid - a race condition exists vs outstanding page faults.
    
    To prevent this, the pasid_state object contains a refcount.
        * set to 1 on pasid bind
        * incremented on each ppr notification start
        * decremented on each ppr notification done
        * decremented on pasid unbind
    
    Since refcount_dec assumes that refcount will never reach 0:
      the current implementation causes the following to be invoked on
      pasid unbind:
            REFCOUNT_WARN("decrement hit 0; leaking memory")
    
    Fix this issue by changing refcount_dec to refcount_dec_and_test
    to explicitly handle refcount=1.

    Prepare for mt8188 to fix a two IOMMU HWs share pagetable issue.
    
    We have two MM IOMMU HWs in mt8188, one is VPP-IOMMU, the other is
    VDO-IOMMU. The 2 MM IOMMU HWs share pagetable don't work in this case:
     a) VPP-IOMMU probe firstly.
     b) VDO-IOMMU probe.
     c) The master for VDO-IOMMU probe (means frstdata is vpp-iommu).
     d) The master in another domain probe. No matter it is vdo or vpp.
    Then it still create a new pagetable in step d). The problem is
    "frstdata->bank[0]->m4u_dom" was not initialized. Then when d) enter, it
    still create a new one.
    
    In this patch, we create a new variable "share_dom" for this share
    pgtable case, it should be helpful for readable. and put all the share
    pgtable logic in the mtk_iommu_domain_finalise.
    
    In mt8195, the master of VPP-IOMMU probes before than VDO-IOMMU
    from its dtsi node sequence, we don't see this issue in it. Prepare for

    Even the PCI devices don't support pasid capability, PASID table is
    mandatory for a PCI device in scalable mode. However flushing cache
    of pasid directory table for these devices are not taken after pasid
    table is allocated as the "size" of table is zero. Fix it by
    calculating the size by page order.
    
    Found this when reading the code, no real problem encountered for now.

    iommu: rockchip: Fix directory table address encoding
    
    [ Upstream commit 6df63b7ebdaf5fcd75dceedf6967d0761e56eca1 ]
    
    The physical address to the directory table is currently encoded using
    the following bit layout for IOMMU v2.
    
     31:12 - Address bit 31:0
     11: 4 - Address bit 39:32
    
    This is also the bit layout used by the vendor kernel.
    
    However, testing has shown that addresses to the directory/page tables
    and memory pages are all encoded using the same bit layout.
    
    IOMMU v1:
     31:12 - Address bit 31:0
    
    IOMMU v2:
     31:12 - Address bit 31:0
     11: 8 - Address bit 35:32
      7: 4 - Address bit 39:36
    
    Change to use the mk_dtentries ops to encode the directory table address
    correctly. The value written to DTE_ADDR may include the valid bit set,
    a bit that is ignored and DTE_ADDR reg read it back as 0.
    
    This also update the bit layout comment for the page address and the
    number of nybbles that are read back for DTE_ADDR comment.
    
    These changes render the dte_addr_phys and dma_addr_dte ops unused and
    is removed.

kbuild: rust_is_available: add check for `bindgen` invocation [+ + +]
Author: Miguel Ojeda <[email protected]>
Date:   Fri Jun 16 02:16:25 2023 +0200

    kbuild: rust_is_available: add check for `bindgen` invocation
    
    [ Upstream commit 52cae7f28ed6c3992489f16bb355f5b623f0912e ]
    
    `scripts/rust_is_available.sh` calls `bindgen` with a special
    header in order to check whether the `libclang` version in use
    is suitable.
    
    However, the invocation itself may fail if, for instance, `bindgen`
    cannot locate `libclang`. This is fine for Kconfig (since the
    script will still fail and therefore disable Rust as it should),
    but it is pretty confusing for users of the `rustavailable` target
    given the error will be unrelated:
    
        ./scripts/rust_is_available.sh: 21: arithmetic expression: expecting primary: "100000 *  + 100 *  + "
        make: *** [Makefile:1816: rustavailable] Error 2
    
    Instead, run the `bindgen` invocation independently in a previous
    step, saving its output and return code. If it fails, then show
    the user a proper error message. Otherwise, continue as usual
    with the saved output.
    
    Since the previous patch we show a reference to the docs, and
    the docs now explain how `bindgen` looks for `libclang`,
    thus the error message can leverage the documentation, avoiding
    duplication here (and making users aware of the setup guide in
    the documentation).

    [ Upstream commit 9eb7e20e0c5cd069457845f965b3e8a7d736ecb7 ]
    
    `bindgen`'s output for `libclang`'s version check contains paths, which
    in turn may contain strings that look like version numbers [1][2]:
    
        .../6.1.0-dev/.../rust_is_available_bindgen_libclang.h:2:9: warning: clang version 11.1.0  [-W#pragma-messages], err: false
    
    which the script will pick up as the version instead of the latter.
    
    It is also the case that versions may appear after the actual version
    (e.g. distribution's version text), which was the reason behind `head` [3]:
    
        .../rust-is-available-bindgen-libclang.h:2:9: warning: clang version 13.0.0 (Fedora 13.0.0-3.fc35) [-W#pragma-messages], err: false
    
    Thus instead ask for a match after the `clang version` string.

    kbuild: rust_is_available: fix version check when CC has multiple arguments
    
    [ Upstream commit dee3a6b819c96fc8b1907577f585fd66f5c0fefe ]
    
    rust_is_available.sh uses cc-version.sh to identify which C compiler is
    in use, as scripts/Kconfig.include does.  cc-version.sh isn't designed to
    be able to handle multiple arguments in one variable, i.e. "ccache clang".
    Its invocation in rust_is_available.sh quotes "$CC", which makes
    $1 == "ccache clang" instead of the intended $1 == ccache & $2 == clang.
    
    cc-version.sh could also be changed to handle having "ccache clang" as one
    argument, but it only has the one consumer upstream, making it simpler to
    fix the caller here.

    ksmbd doesn't support compound read. If client send read-read in
    compound to ksmbd, there can be memory leak from read buffer.
    Windows and linux clients doesn't send it to server yet. For now,
    No response from compound read. compound read will be supported soon.

    `smb2_get_msg()` in smb2_get_ksmbd_tcon() and smb2_check_user_session()
    will always return the first request smb2 header in a compound request.
    if `SMB2_TREE_CONNECT_HE` is the first command in compound request, will

kvm/vfio: ensure kvg instance stays around in kvm_vfio_group_add() [+ + +]

    kvm/vfio: ensure kvg instance stays around in kvm_vfio_group_add()
    
    [ Upstream commit 9e0f4f2918c2ff145d3dedee862d9919a6ed5812 ]
    
    kvm_vfio_group_add() creates kvg instance, links it to kv->group_list,
    and calls kvm_vfio_file_set_kvm() with kvg->file as an argument after
    dropping kv->lock. If we race group addition and deletion calls, kvg
    instance may get freed by the time we get around to calling
    kvm_vfio_file_set_kvm().
    
    Previous iterations of the code did not reference kvg->file outside of
    the critical section, but used a temporary variable. Still, they had
    similar problem of the file reference being owned by kvg structure and
    potential for kvm_vfio_group_del() dropping it before
    kvm_vfio_group_add() had a chance to complete.
    
    Fix this by moving call to kvm_vfio_file_set_kvm() under the protection
    of kv->lock. We already call it while holding the same lock when vfio
    group is being deleted, so it should be safe here as well.

KVM: x86/mmu: Add "never" option to allow sticky disabling of nx_huge_pages [+ + +]

    KVM: x86/mmu: Add "never" option to allow sticky disabling of nx_huge_pages
    
    commit 0b210faf337314e4bc88e796218bc70c72a51209 upstream.
    
    Add a "never" option to the nx_huge_pages module param to allow userspace
    to do a one-way hard disabling of the mitigation, and don't create the
    per-VM recovery threads when the mitigation is hard disabled.  Letting
    userspace pinky swear that userspace doesn't want to enable NX mitigation
    (without reloading KVM) allows certain use cases to avoid the latency
    problems associated with spawning a kthread for each VM.
    
    E.g. in FaaS use cases, the guest kernel is trusted and the host may
    create 100+ VMs per logical CPU, which can result in 100ms+ latencies when
    a burst of VMs is created.

    leds: multicolor: Use rounded division when calculating color components
    
    [ Upstream commit 065d099f1be58187e6629273c50b948a02b7e1bf ]
    
    Given channel intensity, LED brightness and max LED brightness, the
    multicolor LED framework helper led_mc_calc_color_components() computes
    the color channel brightness as
    
        chan_brightness = brightness * chan_intensity / max_brightness
    
    Consider the situation when (brightness, intensity, max_brightness) is
    for example (16, 15, 255), then chan_brightness is computed to 0
    although the fractional divison would give 0.94, which should be rounded
    to 1.
    
    Use DIV_ROUND_CLOSEST here for the division to give more realistic
    component computation:
    
        chan_brightness = DIV_ROUND_CLOSEST(brightness * chan_intensity,
                                            max_brightness)

    leds: trigger: tty: Do not use LED_ON/OFF constants, use led_blink_set_oneshot instead
    
    [ Upstream commit 730094577e0c37e1bc40be37cbd41f71b0a8a2a4 ]
    
    The tty LED trigger uses the obsolete LED_ON & LED_OFF constants when
    setting LED brightness. This is bad because the LED_ON constant is equal
    to 1, and so when activating the tty LED trigger on a LED class device
    with max_brightness greater than 1, the LED is dimmer than it can be
    (when max_brightness is 255, the LED is very dimm indeed; some devices
    translate 1/255 to 0, so the LED is OFF all the time).
    
    Instead of directly setting brightness to a specific value, use the
    led_blink_set_oneshot() function from LED core to configure the blink.
    This function takes the current configured brightness as blink
    brightness if not zero, and max brightness otherwise.
    
    This also changes the behavior of the TTY LED trigger. Previously if
    rx/tx stats kept changing, the LED was ON all the time they kept
    changing. With this patch the LED will blink on TTY activity.

    libbpf: Fix realloc API handling in zero-sized edge cases
    
    [ Upstream commit 8a0260dbf6553c969248b6530cafadac46562f47 ]
    
    realloc() and reallocarray() can either return NULL or a special
    non-NULL pointer, if their size argument is zero. This requires a bit
    more care to handle NULL-as-valid-result situation differently from
    NULL-as-error case. This has caused real issues before ([0]), and just
    recently bit again in production when performing bpf_program__attach_usdt().
    
    This patch fixes 4 places that do or potentially could suffer from this
    mishandling of NULL, including the reported USDT-related one.
    
    There are many other places where realloc()/reallocarray() is used and
    NULL is always treated as an error value, but all those have guarantees
    that their size is always non-zero, so those spot don't need any extra
    handling.

    [ Upstream commit a171fbec88a2c730b108c7147ac5e7b2f5a02b47 ]
    
    LWTUNNEL_XMIT_CONTINUE is implicitly assumed in ip(6)_finish_output2,
    such that any positive return value from a xmit hook could cause
    unexpected continue behavior, despite that related skb may have been
    freed. This could be error-prone for future xmit hook ops. One of the
    possible errors is to return statuses of dst_output directly.
    
    To make the code safer, redefine LWTUNNEL_XMIT_CONTINUE value to
    distinguish from dst_output statuses and check the continue
    condition explicitly.

    [ Upstream commit 29b22badb7a84b783e3a4fffca16f7768fb31205 ]
    
    BPF encap ops can return different types of positive values, such like
    NET_RX_DROP, NET_XMIT_CN, NETDEV_TX_BUSY, and so on, from function
    skb_do_redirect and bpf_lwt_xmit_reroute. At the xmit hook, such return
    values would be treated implicitly as LWTUNNEL_XMIT_CONTINUE in
    ip(6)_finish_output2. When this happens, skbs that have been freed would
    continue to the neighbor subsystem, causing use-after-free bug and
    kernel crashes.
    
    To fix the incorrect behavior, skb_do_redirect return values can be
    simply discarded, the same as tc-egress behavior. On the other hand,
    bpf_lwt_xmit_reroute returns useful errors to local senders, e.g. PMTU
    information. Thus convert its return values to avoid the conflict with
    LWTUNNEL_XMIT_CONTINUE.

    [ Upstream commit a7a2ef0c4b3efbd7d6f3fabd87dbbc0b3f2de5af ]
    
    While looking at a bug, I got rather confused by the layout of the
    'status' field in ieee80211_tx_info. Apparently, the intention is that
    status_driver_data[] is used for driver specific data, and fills up the
    size of the union to 40 bytes, just like the other ones.
    
    This is indeed what actually happens, but only because of the
    combination of two mistakes:
    
     - "void *status_driver_data[18 / sizeof(void *)];" is intended
       to be 18 bytes long but is actually two bytes shorter because of
       rounding-down in the division, to a multiple of the pointer
       size (4 bytes or 8 bytes).
    
     - The other fields combined are intended to be 22 bytes long, but
       are actually 24 bytes because of padding in front of the
       unaligned tx_time member, and in front of the pointer array.
    
    The two mistakes cancel out. so the size ends up fine, but it seems
    more helpful to make this explicit, by having a multiple of 8 bytes
    in the size calculation and explicitly describing the padding.

    md/md-bitmap: hold 'reconfig_mutex' in backlog_store()
    
    [ Upstream commit 44abfa6a95df425c0660d56043020b67e6d93ab8 ]
    
    Several reasons why 'reconfig_mutex' should be held:
    
    1) rdev_for_each() is not safe to be called without the lock, because
       rdev can be removed concurrently.
    2) mddev_destroy_serial_pool() and mddev_create_serial_pool() should not
       be called concurrently.
    3) mddev_suspend() from mddev_destroy/create_serial_pool() should be
       protected by the lock.

    md/raid0: Fix performance regression for large sequential writes
    
    [ Upstream commit 319ff40a542736d67e5bce18635de35d0e7a0bff ]
    
    Commit f00d7c85be9e ("md/raid0: fix up bio splitting.") among other
    things changed how bio that needs to be split is submitted. Before this
    commit, we have split the bio, mapped and submitted each part. After
    this commit, we map only the first part of the split bio and submit the
    second part unmapped. Due to bio sorting in __submit_bio_noacct() this
    results in the following request ordering:
    
      9,0   18     1181     0.525037895 15995  Q  WS 1479315464 + 63392
    
      Split off chunk-sized (1024 sectors) request:
    
      9,0   18     1182     0.629019647 15995  X  WS 1479315464 / 1479316488
    
      Request is unaligned to the chunk so it's split in
      raid0_make_request().  This is the first part mapped and punted to
      bio_list:
    
      8,0   18     7053     0.629020455 15995  A  WS 739921928 + 1016 <- (9,0) 1479315464
    
      Now raid0_make_request() returns, second part is postponed on
      bio_list. __submit_bio_noacct() resorts the bio_list, mapped request
      is submitted to the underlying device:
    
      8,0   18     7054     0.629022782 15995  G  WS 739921928 + 1016
    
      Now we take another request from the bio_list which is the remainder
      of the original huge request. Split off another chunk-sized bit from
      it and the situation repeats:
    
      9,0   18     1183     0.629024499 15995  X  WS 1479316488 / 1479317512
      8,16  18     6998     0.629025110 15995  A  WS 739921928 + 1016 <- (9,0) 1479316488
      8,16  18     6999     0.629026728 15995  G  WS 739921928 + 1016
      ...
      9,0   18     1184     0.629032940 15995  X  WS 1479317512 / 1479318536 [libnetacq-write]
      8,0   18     7059     0.629033294 15995  A  WS 739922952 + 1016 <- (9,0) 1479317512
      8,0   18     7060     0.629033902 15995  G  WS 739922952 + 1016
      ...
    
      This repeats until we consume the whole original huge request. Now we
      finally get to processing the second parts of the split off requests
      (in reverse order):
    
      8,16  18     7181     0.629161384 15995  A  WS 739952640 + 8 <- (9,0) 1479377920
      8,0   18     7239     0.629162140 15995  A  WS 739952640 + 8 <- (9,0) 1479376896
      8,16  18     7186     0.629163881 15995  A  WS 739951616 + 8 <- (9,0) 1479375872
      8,0   18     7242     0.629164421 15995  A  WS 739951616 + 8 <- (9,0) 1479374848
      ...
    
    I guess it is obvious that this IO pattern is extremely inefficient way
    to perform sequential IO. It also makes bio_list to grow to rather long
    lengths.
    
    Change raid0_make_request() to map both parts of the split bio. Since we
    know we are provided with at most chunk-sized bios, we will always need
    to split the incoming bio at most once.

    After the commit 9631abdbf406c("md: Set MD_BROKEN for RAID1 and RAID10")
    MD_BROKEN must be set if array is failed because state_store() checks it.
    If it is set then -EBUSY is returned to userspace.
    
    For raid0 and linear MD_BROKEN is not set by error_handler(). As a result
    mdadm is unable to trigger clean-up actions. It is a regression.
    
    This patch adds appropriate error_handler for raid0 and linear. The
    error handler sets MD_BROKEN for this device.

    md: Change active_io to percpu
    
    [ Upstream commit 72adae23a72cb12e2ef0dcd7c0aa042867f27998 ]
    
    Now the type of active_io is atomic. It's used to count how many ios are
    in the submitting process and it's added and decreased very time. But it
    only needs to check if it's zero when suspending the raid. So we can
    switch atomic to percpu to improve the performance.
    
    After switching active_io to percpu type, we use the state of active_io
    to judge if the raid device is suspended. And we don't need to wake up
    ->sb_wait in md_handle_request anymore. It's done in the callback function
    which is registered when initing active_io. The argument mddev->suspended
    is only used to count how many users are trying to set raid to suspend
    state.

    null-ptr-deference for 'active_io' by moving percpu_ref_exit() to

    percpu_ref_exit

    Before the commit, 'writes_pending' is exited when mddev is freed, and
    it's safe to restart raid because mddev_init_writes_pending() already make
    sure that 'writes_pending' will only be initialized once.
    
    Fix the prblem by moving 'writes_pending' back, it's a litter hard to find
    the relationship between alloc memory and free memory, however, code
    changes is much less and we lived with this for a long time already.

    md: Free resources in __md_stop
    
    commit 3e453522593d74a87cf68a38e14aa36ebca1dbcd upstream.
    
    If md_run() fails after ->active_io is initialized, then percpu_ref_exit
    is called in error path. However, later md_free_disk will call
    percpu_ref_exit again which leads to a panic because of null pointer
    dereference. It can also trigger this bug when resources are initialized
    but are freed in error path, then will be freed again in md_free_disk.

md: raid0: account for split bio in iostat accounting [+ + +]

    md: raid0: account for split bio in iostat accounting
    
    [ Upstream commit cc22b5407e9ca76adb7efeed843146510b1b72a5 ]
    
    When a bio is split by md raid0, the newly created bio will not be tracked
    by md for I/O accounting. Only the portion of I/O still assigned to the
    original bio which was reduced by the split will be accounted for. This
    results in md iostat data sometimes showing I/O values far below the actual
    amount of data being sent through md.
    
    md_account_bio() needs to be called for all bio generated by the bio split.
    
    A simple example of the issue was generated using a raid0 device on partitions
    to the same device. Since all raid0 I/O then goes to one device, it makes it
    easy to see a gap between the md device and its sd storage. Reading an lvm
    device on top of the md device, the iostat output (some 0 columns and extra
    devices removed to make the data more compact) was:

    I/O was generated doing large direct I/O reads (12M) with dd to a linear
    lvm volume on top of the 4 leg raid0 device.
    
    The md2 reads were showing as roughly 2/3 of the reads to the sde device
    containing all of md2's raid partitions. The sum of reads to sde was
    1826816 kB, which was the expected amount as it was the amount read by
    dd. With the patch, the total reads from md will match the reads from
    sde and be consistent with the amount of I/O generated.

    memalloc_noio_save() is called for the first mddev_suspend(), and
    repeated mddev_suspend() only increase 'suspended'. However,
    memalloc_noio_restore() is also called for the first mddev_resume(),
    which means that memory reclaim will be enabled before the last

    [ Upstream commit f126ff7e4024f6704e6ec0d4137037568708a3c7 ]
    
    The supported ad5820 and ad5821 VCMs both use a single 16 bit register
    which is written by sending 2 bytes with the data directly after sending
    the i2c-client address.
    
    The ad5823 OTOH has a more typical i2c / smbus device setup with multiple
    8 bit registers where the first byte send after the i2c-client address is
    the register address and the actual data only starts from the second byte
    after the i2c-client address.
    
    The ad5823 i2c_ and of_device_id-s was added at the same time as
    the ad5821 ids with as rationale:
    
    """
    Some camera modules also refer that AD5823 is a replacement of AD5820:
    https://download.kamami.com/p564094-OV8865_DS.pdf
    """
    
    The AD5823 may be an electrical and functional replacement of the AD5820,
    but from a software pov it is not compatible at all and it is going to
    need its own driver, drop its id from the ad5820 driver.

    media: cec: core: add adap_nb_transmit_canceled() callback
    
    [ Upstream commit da53c36ddd3f118a525a04faa8c47ca471e6c467 ]
    
    A potential deadlock was found by Zheng Zhang with a local syzkaller
    instance.
    
    The problem is that when a non-blocking CEC transmit is canceled by calling
    cec_data_cancel, that in turn can call the high-level received() driver
    callback, which can call cec_transmit_msg() to transmit a new message.
    
    The cec_data_cancel() function is called with the adap->lock mutex held,
    and cec_transmit_msg() tries to take that same lock.
    
    The root cause is that the received() callback can either be used to pass
    on a received message (and then adap->lock is not held), or to report a
    canceled transmit (and then adap->lock is held).
    
    This is confusing, so create a new low-level adap_nb_transmit_canceled
    callback that reports back that a non-blocking transmit was canceled.
    
    And the received() callback is only called when a message is received,
    as was the case before commit f9d0ecbf56f4 ("media: cec: correctly pass
    on reply results") complicated matters.

    [ Upstream commit 948a77aaecf202f722cf2264025f9987e5bd5c26 ]
    
    The adap_configured() callback was called with the adap->lock mutex
    held if the 'configured' argument was false, and without the adap->lock
    mutex held if that argument was true.
    
    That was very confusing, and so split this up in a adap_unconfigured()
    callback and a high-level configured() callback.
    
    This also makes it easier to understand when the mutex is held: all
    low-level adap_* callbacks are called with the mutex held. All other
    callbacks are called without that mutex held.

    commit 86495af1171e1feec79faa9b64c05c89f46e41d1 upstream.
    
    In commit 9011e49d54dc ("modules: only allow symbol_get of
    EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted
    to GPL-only marked symbols.  This interacts oddly with the DVB logic

    The if statement that compares msgs[i].len != 3 is always false because
    it is in a code block where msg[i].len is equal to 3. The check is
    redundant and can be removed.

    media: i2c: Add a camera sensor top level menu
    
    commit 7d3c7d2a2914e10bec3b9cdacdadb8e1f65f715a upstream.
    
    Select V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API for all sensor drivers. This
    also adds the options to drivers that don't specifically need them, these
    are still seldom used drivers using old APIs. The upside is that these
    should now all compile --- many drivers have had missing dependencies.
    
    The "menu" is replaced by selectable "menuconfig" to select the needed
    V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API options.
    
    Also select MEDIA_CONTROLLER which VIDEO_V4L2_SUBDEV_API effectively
    depends on, and add the I2C dependency to the menu.

    media: mediatek: vcodec: fix potential double free
    
    [ Upstream commit be40f524b6edac4fb9a98ef79620fd9b9497a998 ]
    
    The "lat_buf->private_data" needs to be set to NULL to prevent a
    double free.  How this would happen is if vdec_msg_queue_init() failed
    twice in a row and on the second time it failed earlier than on the
    first time.
    
    The vdec_msg_queue_init() function has a loop which does:
            for (i = 0; i < NUM_BUFFER_COUNT; i++) {
    
    Each iteration initializes one element in the msg_queue->lat_buf[] array
    and then the clean up function vdec_msg_queue_deinit() frees each
    element of the msg_queue->lat_buf[] array.  This clean up code relies
    on the assumption that every element is either initialized or zeroed.
    Leaving a freed pointer which is non-zero breaks the assumption.

    If we encounter any error in the vdec_msg_queue_init() then we need
    to set "msg_queue->wdma_addr.size = 0;".  Normally, this is done
    inside the vdec_msg_queue_deinit() function.  However, if the
    first call to allocate &msg_queue->wdma_addr fails, then the
    vdec_msg_queue_deinit() function is a no-op.  For that situation, just
    set the size to zero explicitly and return.
    
    There were two other error paths which did not clean up before returning.
    Change those error paths to goto mem_alloc_err.

    a v4l2_mbus_framefmt struct needs to be filled in so that the driver always

    This is a preparation patch for fixing ov2680_set_fmt()
    which == V4L2_SUBDEV_FORMAT_TRY calls not properly filling in
    the passed in v4l2_mbus_framefmt struct.
    
    Note that for ov2680_init_cfg() this now simply always fills
    the try_fmt struct of the passed in sd_state. This is correct because
    ov2680_init_cfg() is never called with a NULL sd_state so the old
    sd_state check is not necessary.

    [ Upstream commit 50a7bad4e0a37d7018ab6fe843dd84bc6b2ecf72 ]
    
    The index into ov2680_hv_flip_bayer_order[] should be 0-3, but
    ov2680_bayer_order() was using 0 + BIT(2) + (BIT(2) << 1) as
    max index, while the intention was to use: 0 + 1 + 2 as max index.
    
    Fix the index calculation in ov2680_bayer_order(), while at it
    also just use the ctrl values rather then reading them back using
    a slow i2c-read transaction.
    
    This also allows making the function void, since there now are
    no more i2c-reads to error check.
    
    Note the check for the ctrls being NULL is there to allow
    adding an ov2680_fill_format() helper later, which will call
    ov2680_set_bayer_order() during probe() before the ctrls are created.

    media: ov2680: Fix ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY not working
    
    [ Upstream commit c0e97a4b4f20639f74cd5809b42ba6cbf9736a7d ]
    
    ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY was getting
    the try_fmt v4l2_mbus_framefmt struct from the passed in sd_state
    and then storing the contents of that into the return by reference
    format->format struct.
    
    While the right thing to do would be filling format->format based on
    the just looked up mode and then store the results of that in
    sd_state->pads[0].try_fmt .
    
    Before the previous change introducing ov2680_fill_format() this
    resulted in ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY always
    returning the zero-ed out sd_state->pads[0].try_fmt in format->format
    breaking callers using this.
    
    After the introduction of ov2680_fill_format() which at least
    initializes sd_state->pads[0].try_fmt properly, format->format
    is now always being filled with the default 800x600 mode set by
    ov2680_init_cfg() independent of the actual requested mode.
    
    Move the filling of format->format with ov2680_fill_format() to
    before the if (which == V4L2_SUBDEV_FORMAT_TRY) and then store
    the filled in format->format in sd_state->pads[0].try_fmt to
    fix this.
    
    Note this removes the fmt local variable because IMHO having a local
    variable which points to a sub-struct of one of the function arguments
    just leads to confusion when reading the code.

    auto-exposure and auto-gain do not work.
    
    Note that the code setting the auto-exposure flag was broken, callers
    of ov2680_exposure_set() were directly passing !!ctrls->auto_exp->val as
    "bool auto_exp" value, but ctrls->auto_exp is a menu control with:
    
    enum  v4l2_exposure_auto_type {
            V4L2_EXPOSURE_AUTO = 0,
            V4L2_EXPOSURE_MANUAL = 1,
            ...
    
    So instead of passing !!ctrls->auto_exp->val they should have been passing
    ctrls->auto_exp->val == V4L2_EXPOSURE_AUTO, iow the passed value was
    inverted of what it should have been.
    
    Also remove ov2680_g_volatile_ctrl() since without auto support the gain
    and exposure controls are not volatile.
    
    This also fixes the control values not being properly applied in
    ov2680_mode_set(). The 800x600 mode register-list also sets gain,
    exposure and vflip overriding the last set ctrl values.
    
    ov2680_mode_set() does call ov2680_gain_set() and ov2680_exposure_set()
    but did this before writing the mode register-list, so these values
    would still be overridden by the mode register-list.
    
    Add a v4l2_ctrl_handler_setup() call after writing the mode register-list
    to restore all ctrl values. Also remove the ctrls->gain->is_new check from
    ov2680_gain_set() so that the gain always gets restored properly.
    
    Last since ov2680_mode_set() now calls v4l2_ctrl_handler_setup(), remove
    the v4l2_ctrl_handler_setup() call after ov2680_mode_restore() since
    ov2680_mode_restore() calls ov2680_mode_set().

    Set OV5640_REG_IO_MIPI_CTRL00 bit 2 to 1 instead of 0, since 1 means
    MIPI CSI2 interface, while 0 means CPI parallel interface.
    
    In the ov5640_set_power_mipi() the interface should obviously be set
    to MIPI CSI2 since this functions is used to power up the sensor when
    operated in MIPI CSI2 mode. The sensor should not be in CPI mode in
    that case.
    
    This fixes a corner case where capturing the first frame on i.MX8MN
    with CSI/ISI resulted in corrupted frame.

    The initial state of RESETB input signal of OV5640 should be
    asserted, i.e. the sensor should be in reset. This is not the
    case, make it so.
    
    Since the subsequent assertion of RESETB signal is no longer
    necessary and the timing of the power sequencing could be
    slightly adjusted, add annotations to the delays which match
    OV5640 datasheet rev. 2.03, both:
      figure 2-3 power up timing with internal DVDD
      figure 2-4 power up timing with external DVDD source
    
    The 5..10ms delay between PWDN assertion and RESETB assertion
    is not even documented in the power sequencing diagram, and
    with this reset fix, it is no longer even necessary.

    media: ov5640: fix low resolution image abnormal issue
    
    [ Upstream commit a828002f38c5ee49d3f0c0e64c0f0caa1aec8dc2 ]
    
    OV5640 will output abnormal image data when work at low resolution
    (320x240, 176x144 and 160x120) after switching from high resolution,
    such as 1080P, the time interval between high and low switching must
    be less than 1000ms in order to OV5640 don't enter suspend state during
    the time.
    
    The reason is by 0x3824 value don't restore to initialize value when
    do resolution switching. In high resolution setting array, 0x3824 is
    set to 0x04, but low resolution setting array remove 0x3824 in commit
    db15c1957a2d ("media: ov5640: Remove duplicated mode settings"). So
    when do resolution switching from high to low, such as 1080P to 320x240,
    and the time interval is less than auto suspend delay time which means
    global initialize setting array will not be loaded, the output image
    data are abnormal. Hence move 0x3824 from ov5640_init_setting[] table
    to ov5640_setting_low_res[] table and also move 0x4407 0x460b, 0x460c
    to avoid same issue.

    mtd: rawnand: brcmnand: Fix mtd oobsize
    
    [ Upstream commit 60177390fa061c62d156f4a546e3efd90df3c183 ]
    
    brcmnand controller can only access the flash spare area up to certain
    bytes based on the ECC level. It can be less than the actual flash spare
    area size. For example, for many NAND chip supporting ECC BCH-8, it has
    226 bytes spare area. But controller can only uses 218 bytes. So brcmand
    driver overrides the mtd oobsize with the controller's accessible spare

    resets the oobsize back to the actual flash spare aprea size from

    net-memcg: Fix scope of sockmem pressure indicators
    
    [ Upstream commit ac8a52962164a50e693fa021d3564d7745b83a7f ]
    
    Now there are two indicators of socket memory pressure sit inside
    struct mem_cgroup, socket_pressure and tcpmem_pressure, indicating
    memory reclaim pressure in memcg->memory and ->tcpmem respectively.
    
    When in legacy mode (cgroupv1), the socket memory is charged into
    ->tcpmem which is independent of ->memory, so socket_pressure has
    nothing to do with socket's pressure at all. Things could be worse
    by taking socket_pressure into consideration in legacy mode, as a
    pressure in ->memory can lead to premature reclamation/throttling
    in socket.
    
    While for the default mode (cgroupv2), the socket memory is charged
    into ->memory, and ->tcpmem/->tcpmem_pressure are simply not used.
    
    So {socket,tcpmem}_pressure are only used in default/legacy mode
    respectively for indicating socket memory pressure. This patch fixes
    the pieces of code that make mixed use of both.

net: Avoid address overwrite in kernel_connect [+ + +]
Author: Jordan Rife <[email protected]>
Date:   Mon Aug 21 16:45:23 2023 -0500

    net: Avoid address overwrite in kernel_connect
    
    commit 0bdf399342c5acbd817c9098b6c7ed21f1974312 upstream.
    
    BPF programs that run on connect can rewrite the connect address. For
    the connect system call this isn't a problem, because a copy of the address
    is made when it is moved into kernel space. However, kernel_connect
    simply passes through the address it is given, so the caller may observe
    its address value unexpectedly change.
    
    A practical example where this is problematic is where NFS is combined
    with a system such as Cilium which implements BPF-based load balancing.
    A common pattern in software-defined storage systems is to have an NFS
    mount that connects to a persistent virtual IP which in turn maps to an
    ephemeral server IP. This is usually done to achieve high availability:
    if your server goes down you can quickly spin up a replacement and remap
    the virtual IP to that endpoint. With BPF-based load balancing, mounts
    will forget the virtual IP address when the address rewrite occurs
    because a pointer to the only copy of that address is passed down the
    stack. Server failover then breaks, because clients have forgotten the
    virtual IP address. Reconnects fail and mounts remain broken. This patch
    was tested by setting up a scenario like this and ensuring that NFS
    reconnects worked after applying the patch.

    net: dsa: microchip: KSZ9477 register regmap alignment to 32 bit boundaries
    
    [ Upstream commit 8d7ae22ae9f8c8a4407f8e993df64440bdbd0cee ]
    
    The commit (SHA1: 5c844d57aa7894154e49cf2fc648bfe2f1aefc1c) provided code
    to apply "Module 6: Certain PHY registers must be written as pairs instead
    of singly" errata for KSZ9477 as this chip for certain PHY registers
    (0xN120 to 0xN13F, N=1,2,3,4,5) must be accesses as 32 bit words instead
    of 16 or 8 bit access.
    Otherwise, adjacent registers (no matter if reserved or not) are
    overwritten with 0x0.
    
    Without this patch some registers (e.g. 0x113c or 0x1134) required for 32
    bit access are out of valid regmap ranges.
    
    As a result, following error is observed and KSZ9477 is not properly
    configured:
    
    ksz-switch spi1.0: can't rmw 32bit reg 0x113c: -EIO
    ksz-switch spi1.0: can't rmw 32bit reg 0x1134: -EIO
    ksz-switch spi1.0 lan1 (uninitialized): failed to connect to PHY: -EIO
    ksz-switch spi1.0 lan1 (uninitialized): error -5 setting up PHY for tree 0, switch 0, port 0
    
    The solution is to modify regmap_reg_range to allow accesses with 4 bytes
    boundaries.

    [ Upstream commit db1a6ad77c180efc7242d7204b9a0c72c8a5a1bb ]
    
    Handle extended compliance code 0x1 (SFF8024_ECC_100G_25GAUI_C2M_AOC)
    for active optical cables supporting 25G and 100G speeds.
    
    Since the specification makes no statement about transmitter range, and
    as the specific sfp module that had been tested features only 2m fiber -
    short-range (SR) modes are selected.
    
    The 100G speed is irrelevant because it would require multiple fibers /
    multiple SFP28 modules combined under one netdev.
    sfp-bus.c only handles a single module per netdev, so only 25Gbps modes
    are selected.
    
    sfp_parse_support already handles SFF8024_ECC_100GBASE_SR4_25GBASE_SR
    with compatible properties, however that entry is a contradiction in
    itself since with SFP(28) 100GBASE_SR4 is impossible - that would likely
    be a mode for qsfp modules only.
    
    Add a case for SFF8024_ECC_100G_25GAUI_C2M_AOC selecting 25gbase-r
    interface mode and 25000baseSR link mode.
    Also enforce SFP28 bitrate limits on the values read from sfp eeprom as
    requested by Russell King.

    net: tcp: fix unexcepted socket die when snd_wnd is 0
    
    [ Upstream commit e89688e3e97868451a5d05b38a9d2633d6785cd4 ]
    
    In tcp_retransmit_timer(), a window shrunk connection will be regarded
    as timeout if 'tcp_jiffies32 - tp->rcv_tstamp > TCP_RTO_MAX'. This is not
    right all the time.
    
    The retransmits will become zero-window probes in tcp_retransmit_timer()
    if the 'snd_wnd==0'. Therefore, the icsk->icsk_rto will come up to
    TCP_RTO_MAX sooner or later.
    
    However, the timer can be delayed and be triggered after 122877ms, not
    TCP_RTO_MAX, as I tested.
    
    Therefore, 'tcp_jiffies32 - tp->rcv_tstamp > TCP_RTO_MAX' is always true
    once the RTO come up to TCP_RTO_MAX, and the socket will die.
    
    Fix this by replacing the 'tcp_jiffies32' with '(u32)icsk->icsk_timeout',
    which is exact the timestamp of the timeout.
    
    However, "tp->rcv_tstamp" can restart from idle, then tp->rcv_tstamp
    could already be a long time (minutes or hours) in the past even on the
    first RTO. So we double check the timeout with the duration of the
    retransmission.
    
    Meanwhile, making "2 * TCP_RTO_MAX" as the timeout to avoid the socket
    dying too soon.

    commit 050d91c03b28ca479df13dfb02bcd2c60dd6a878 upstream.
    
    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can
    lead to the use of wrong `CIDR_POS(c)` for calculating array offsets,
    which can lead to integer underflow. As a result, it leads to slab
    out-of-bound access.
    This patch adds back the IP_SET_HASH_WITH_NET0 macro to
    ip_set_hash_netportnet to address the issue.

    netfilter: nft_exthdr: Fix non-linear header modification
    
    commit 28427f368f0e08d504ed06e74bc7cc79d6d06511 upstream.
    
    Fix skb_ensure_writable() size. Don't use nft_tcp_header_pointer() to
    make it explicit that pointers point to the packet (not local buffer).

    sctp_mt_check doesn't validate the flag_count field. An attacker can
    take advantage of that to trigger a OOB read and leak memory
    information.
    
    Add the field validation in the checkentry function.

    The xt_u32 module doesn't validate the fields in the xt_u32 structure.

netrom: Deny concurrent connect(). [+ + +]
Author: Kuniyuki Iwashima <[email protected]>
Date:   Thu Aug 24 09:50:59 2023 -0700

    netrom: Deny concurrent connect().
    
    [ Upstream commit c2f8fd7949603efb03908e05abbf7726748c8de3 ]
    
    syzkaller reported null-ptr-deref [0] related to AF_NETROM.
    This is another self-accept issue from the strace log. [1]
    
    syz-executor creates an AF_NETROM socket and calls connect(), which
    is blocked at that time.  Then, sk->sk_state is TCP_SYN_SENT and
    sock->state is SS_CONNECTING.
    
      [pid  5059] socket(AF_NETROM, SOCK_SEQPACKET, 0) = 4
      [pid  5059] connect(4, {sa_family=AF_NETROM, sa_data="..." <unfinished ...>
    
    Another thread calls connect() concurrently, which finally fails
    with -EINVAL.  However, the problem here is the socket state is
    reset even while the first connect() is blocked.
    
      [pid  5060] connect(4, NULL, 0 <unfinished ...>
      [pid  5060] <... connect resumed>)      = -1 EINVAL (Invalid argument)
    
    As sk->state is TCP_CLOSE and sock->state is SS_UNCONNECTED, the
    following listen() succeeds.  Then, the first connect() looks up
    itself as a listener and puts skb into the queue with skb->sk itself.
    As a result, the next accept() gets another FD of itself as 3, and
    the first connect() finishes.
    
      [pid  5060] listen(4, 0 <unfinished ...>
      [pid  5060] <... listen resumed>)       = 0
      [pid  5060] accept(4, NULL, NULL <unfinished ...>
      [pid  5060] <... accept resumed>)       = 3
      [pid  5059] <... connect resumed>)      = 0
    
    Then, accept4() is called but blocked, which causes the general protection
    fault later.
    
      [pid  5059] accept4(4, NULL, 0x20000400, SOCK_NONBLOCK <unfinished ...>
    
    After that, another self-accept occurs by accept() and writev().
    
      [pid  5060] accept(4, NULL, NULL <unfinished ...>
      [pid  5061] writev(3, [{iov_base=...}] <unfinished ...>
      [pid  5061] <... writev resumed>)       = 99
      [pid  5060] <... accept resumed>)       = 6
    
    Finally, the leader thread close()s all FDs.  Since the three FDs
    reference the same socket, nr_release() does the cleanup for it
    three times, and the remaining accept4() causes the following fault.
    
      [pid  5058] close(3)                    = 0
      [pid  5058] close(4)                    = 0
      [pid  5058] close(5)                    = -1 EBADF (Bad file descriptor)
      [pid  5058] close(6)                    = 0
      [pid  5058] <... exit_group resumed>)   = ?

    To avoid the issue, we need to return an error for connect() if
    another connect() is in progress, as done in __inet_stream_connect().

    [ Upstream commit f67b55b6588bcf9316a1e6e8d529100a5aa3ebe6 ]
    
    Commit 64cfca85bacd asserts the only valid return values for
    nfs2/3_decode_dirent should not include -ENAMETOOLONG, but for a server
    that sends a filename3 which exceeds MAXNAMELEN in a READDIR response the
    client's behavior will be to endlessly retry the operation.
    
    We could map -ENAMETOOLONG into -EBADCOOKIE, but that would produce
    truncated listings without any error.  The client should return an error
    for this case to clearly assert that the server implementation must be
    corrected.

NFSD: da_addr_body field missing in some GETDEVICEINFO replies [+ + +]

Date:   Wed Aug 16 10:20:52 2023 -0400

    NFSD: da_addr_body field missing in some GETDEVICEINFO replies
    
    [ Upstream commit 6372e2ee629894433fe6107d7048536a3280a284 ]
    
    The XDR specification in RFC 8881 looks like this:
    
    struct device_addr4 {
            layouttype4     da_layout_type;
            opaque          da_addr_body<>;
    };
    
    struct GETDEVICEINFO4resok {
            device_addr4    gdir_device_addr;
            bitmap4         gdir_notification;
    };
    
    union GETDEVICEINFO4res switch (nfsstat4 gdir_status) {
    case NFS4_OK:
            GETDEVICEINFO4resok gdir_resok4;
    case NFS4ERR_TOOSMALL:
            count4          gdir_mincount;
    default:
            void;
    };
    
    Looking at nfsd4_encode_getdeviceinfo() ....
    
    When the client provides a zero gd_maxcount, then the Linux NFS
    server implementation encodes the da_layout_type field and then
    skips the da_addr_body field completely, proceeding directly to
    encode gdir_notification field.
    
    There does not appear to be an option in the specification to skip
    encoding da_addr_body. Moreover, Section 18.40.3 says:
    
    > If the client wants to just update or turn off notifications, it
    > MAY send a GETDEVICEINFO operation with gdia_maxcount set to zero.
    > In that event, if the device ID is valid, the reply's da_addr_body
    > field of the gdir_device_addr field will be of zero length.
    
    Since the layout drivers are responsible for encoding the
    da_addr_body field, put this fix inside the ->encode_getdeviceinfo
    methods.

    NFSv4.2: Rework scratch handling for READ_PLUS
    
    [ Upstream commit fbd2a05f29a95d5b42b294bf47e55a711424965b ]
    
    Instead of using a tiny, static scratch buffer, we should use a kmalloc()-ed
    buffer that is allocated when checking for read plus usage. This lets us
    use the buffer before decoding any part of the READ_PLUS operation
    instead of setting it right before segment decoding, meaning it should
    be a little more robust.

    NFSv4.2: Rework scratch handling for READ_PLUS (again)
    
    commit 303a78052091c81e9003915c521fdca1c7e117af upstream.
    
    I found that the read code might send multiple requests using the same
    nfs_pgio_header, but nfs4_proc_read_setup() is only called once. This is
    how we ended up occasionally double-freeing the scratch buffer, but also
    means we set a NULL pointer but non-zero length to the xdr scratch
    buffer. This results in an oops the first time decoding needs to copy
    something to scratch, which frequently happens when decoding READ_PLUS
    hole segments.
    
    I fix this by moving scratch handling into the pageio read code. I
    provide a function to allocate scratch space for decoding read replies,
    and free the scratch buffer when the nfs_pgio_header is freed.

    ntb: Clean up tx tail index on link down
    
    commit cc79bd2738c2d40aba58b2be6ce47dc0e471df0e upstream.
    
    The tx tail index is not reset when the link goes down. This causes the
    tail index to go out of sync when the link goes down and comes back up.
    Refactor the ntb_qp_link_down_reset() and reset the tail index as well.

    ntb: Drop packets when qp link is down
    
    commit f195a1a6fe416882984f8bd6c61afc1383171860 upstream.
    
    Currently when the transport receive packets after netdev has closed the
    transport returns error and triggers tx errors to be incremented and
    carrier to be stopped. There is no reason to return error if the device is
    already closed. Drop the packet and return 0.

    [ Upstream commit 6b4b2ded9c4282deea421eef144ab0ced954721c ]
    
    1. Upon txschq free request, the transmit schedular config in hardware
    is not getting reset. This patch adds necessary changes to do the same.
    
    2. Current implementation calls txschq alloc during interface
    initialization and in response handler updates the default txschq array.
    This creates a problem for htb offload where txsch alloc will be called
    for every tc class. This patch addresses the issue by reading txschq
    response in mbox caller function instead in the response handler.
    
    3. Current otx2_txschq_stop routine tries to free all txschq nodes
    allocated to the interface. This creates a problem for htb offload.
    This patch introduces the otx2_txschq_free_one to free txschq in a
    given level.

    of: overlay: Call of_changeset_init() early
    
    [ Upstream commit a9515ff4fb142b690a0d2b58782b15903b990dba ]
    
    When of_overlay_fdt_apply() fails, the changeset may be partially
    applied, and the caller is still expected to call of_overlay_remove() to
    clean up this partial state.
    
    However, of_overlay_apply() calls of_resolve_phandles() before
    init_overlay_changeset().  Hence if the overlay fails to apply due to an
    unresolved symbol, the overlay_changeset.cset.entries list is still
    uninitialized, and cleanup will crash with a NULL-pointer dereference in
    overlay_removal_is_ok().
    
    Fix this by moving the call to of_changeset_init() from
    init_overlay_changeset() to of_overlay_fdt_apply(), where all other
    early initialization is done.

    commit 4a032827daa89350365166b19d14d82fe8219128 upstream.
    
    The driver core now:
    - Has the parent device of a supplier pick up the consumers if the
      supplier never has a device created for it.
    - Ignores a supplier if the supplier has no parent device and will never
      be probed by a driver
    
    And already prevents creating a device link with the consumer as a
    supplier of a parent.
    
    So, we no longer need to find the "compatible" node of the supplier or
    do any other checks in of_link_to_phandle(). We simply need to make sure
    that the supplier is available in DT.

    [ Upstream commit e09060b3b6b4661278ff8e1b7b81a37d5ea86eae ]
    
    Don't assume that the device is fully under the control of ASPM and use RMW
    capability accessors which do proper locking to avoid losing concurrent
    updates to the register values.
    
    If configuration fails in pcie_aspm_configure_common_clock(), the
    function attempts to restore the old PCI_EXP_LNKCTL_CCC settings. Store
    only the old PCI_EXP_LNKCTL_CCC bit for the relevant devices rather
    than the content of the whole LNKCTL registers. It aligns better with
    how pcie_lnkctl_clear_and_set() expects its parameter and makes the
    code more obvious to understand.

PCI/PM: Only read PCI_PM_CTRL register when available [+ + +]

Date:   Thu Aug 24 09:37:38 2023 +0800

    PCI/PM: Only read PCI_PM_CTRL register when available
    
    commit 5694ba13b004eea683c6d4faeb6d6e7a9636bda0 upstream.
    
    For a device with no Power Management Capability, pci_power_up() previously
    returned 0 (success) if the platform was able to put the device in D0,
    which led to pci_set_full_power_state() trying to read PCI_PM_CTRL, even
    though it doesn't exist.
    
    Since dev->pm_cap == 0 in this case, pci_set_full_power_state() actually
    read the wrong register, interpreted it as PCI_PM_CTRL, and corrupted
    dev->current_state.  This led to messages like this in some cases:
    
      pci 0000:01:00.0: Refused to change power state from D3hot to D0
    
    To prevent this, make pci_power_up() always return a negative failure code
    if the device lacks a Power Management Capability, even if non-PCI platform
    power management has been able to put the device in D0.  The failure will
    prevent pci_set_full_power_state() from trying to access PCI_PM_CTRL.

PCI: Add locking to RMW PCI Express Capability Register accessors [+ + +]

    PCI: Add locking to RMW PCI Express Capability Register accessors
    
    [ Upstream commit 5e70d0acf0825f439079736080350371f8d6699a ]
    
    Many places in the kernel write the Link Control and Root Control PCI
    Express Capability Registers without proper concurrency control and this
    could result in losing the changes one of the writers intended to make.
    
    Add pcie_cap_lock spinlock into the struct pci_dev and use it to protect
    bit changes made in the RMW capability accessors. Protect only a selected
    set of registers by differentiating the RMW accessor internally to
    locked/unlocked variants using a wrapper which has the same signature as
    pcie_capability_clear_and_set_word(). As the Capability Register (pos)
    given to the wrapper is always a constant, the compiler should be able to
    simplify all the dead-code away.
    
    So far only the Link Control Register (ASPM, hotplug, link retraining,
    various drivers) and the Root Control Register (AER & PME) seem to
    require RMW locking.

PCI: Allow drivers to request exclusive config regions [+ + +]
Author: Ira Weiny <[email protected]>

    PCI: Allow drivers to request exclusive config regions
    
    [ Upstream commit 278294798ac9118412c9624a801d3f20f2279363 ]
    
    PCI config space access from user space has traditionally been
    unrestricted with writes being an understood risk for device operation.
    
    Unfortunately, device breakage or odd behavior from config writes lacks
    indicators that can leave driver writers confused when evaluating
    failures.  This is especially true with the new PCIe Data Object
    Exchange (DOE) mailbox protocol where backdoor shenanigans from user
    space through things such as vendor defined protocols may affect device
    operation without complete breakage.
    
    A prior proposal restricted read and writes completely.[1]  Greg and
    Bjorn pointed out that proposal is flawed for a couple of reasons.
    First, lspci should always be allowed and should not interfere with any
    device operation.  Second, setpci is a valuable tool that is sometimes
    necessary and it should not be completely restricted.[2]  Finally
    methods exist for full lock of device access if required.
    
    Even though access should not be restricted it would be nice for driver
    writers to be able to flag critical parts of the config space such that
    interference from user space can be detected.
    
    Introduce pci_request_config_region_exclusive() to mark exclusive config
    regions.  Such regions trigger a warning and kernel taint if accessed
    via user space.
    
    Create pci_warn_once() to restrict the user from spamming the log.

PCI: apple: Initialize pcie->nvecs before use [+ + +]

    PCI: apple: Initialize pcie->nvecs before use
    
    [ Upstream commit d8650c0c2aa2e413594e4cb0faafa9958c1d7782 ]
    
    The apple_pcie_setup_port() function computes ilog2(pcie->nvecs) to set
    up the number of MSIs available for each port. However, it's called
    before apple_msi_init(), which initializes pcie->nvecs.
    
    Luckily, pcie->nvecs is part of kzalloc()-ed structure and, as such,
    initialized as zero. ilog2(0) happens to be 0xffffffff which then simply
    configures more MSIs in hardware than we have. This doesn't break
    anything because we never hand out those vectors.
    
    Thus, swap the order of the two calls so that the correctly initialized
    value is then used.

    called the discovery method. The existing value of the type->num_boxes
    is from the discovery table.
    
    On some SPR variants, there is a firmware bug that makes the value from the
    discovery table incorrect. We use the value from the

    XCC (Always returns 0), but the above firmware bug doesn't impact the
    EMR XCC.
    
    Don't let the value from the MSR replace the existing value from the

    in the pre pll config table when the fractal divider is used.
    This can prevent proper power_on because a tmdsclock for the new rate
    is not found in the pre pll config table.
    
    Fix this by saving and returning a rounded pixel rate that exist
    in the pre pll config table.

    platform/x86/intel/hid: Add HP Dragonfly G2 to VGBS DMI quirks
    
    [ Upstream commit 7783e97f8558ad7a4d1748922461bc88483fbcdf ]
    
    HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS
    method. If VGBS is not called on boot, the firmware sends an initial
    0xcd event shortly after calling the BTNL method, but only if the device
    is booted in the laptop mode. However, if the device is booted in the
    tablet mode and VGBS is not called, there is no initial 0xcc event, and
    the input device for SW_TABLET_MODE is not registered up until the user
    turns the device into the laptop mode.
    
    Call VGBS on boot on this device to get the initial state of
    SW_TABLET_MODE in a reliable way.
    
    Tested with BIOS 1.13.1.

    On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE
    are only send after the BTNL ACPI method has been called.
    
    Likely more devices need this, so make the BTNL ACPI method unconditional
    instead of only doing it on devices with a 5 button array.
    
    Note this also makes the intel_button_array_enable() call in probe()
    unconditional, that function does its own priv->array check. This makes
    the intel_button_array_enable() call in probe() consistent with the calls
    done on suspend/resume which also rely on the priv->array check inside
    the function.

    [ Upstream commit 2b694fc96fe33a7c042e3a142d27d945c8c668b0 ]
    
    When building the boot wrapper assembly files with clang after
    commit 648a1783fe25 ("powerpc/boot: Fix boot wrapper code generation
    with CONFIG_POWER10_CPU"), the following warnings appear for each file
    built:
    
      '-prefixed' is not a recognized feature for this target (ignoring feature)
      '-pcrel' is not a recognized feature for this target (ignoring feature)
    
    While it is questionable whether or not LLVM should be emitting a
    warning when passed negative versions of code generation flags when
    building assembly files (since it does not emit a warning for the
    altivec and vsx flags), it is easy enough to work around this by just
    moving the disabled flags to BOOTCFLAGS after the assignment of
    BOOTAFLAGS, so that they are not added when building assembly files.
    Do so to silence the warnings.

    powerpc/iommu: Fix notifiers being shared by PCI and VIO buses
    
    [ Upstream commit c37b6908f7b2bd24dcaaf14a180e28c9132b9c58 ]
    
    fail_iommu_setup() registers the fail_iommu_bus_notifier struct to both
    PCI and VIO buses.  struct notifier_block is a linked list node, so this
    causes any notifiers later registered to either bus type to also be
    registered to the other since they share the same node.
    
    This causes issues in (at least) the vgaarb code, which registers a
    notifier for PCI buses.  pci_notify() ends up being called on a vio
    device, converted with to_pci_dev() even though it's not a PCI device,
    and finally makes a bad access in vga_arbiter_add_pci_device() as
    discovered with KASAN:

    In mpc5xxx_fwnode_get_bus_frequency(), we should add
    fwnode_handle_put() when break out of the iteration
    fwnode_for_each_parent_node() as it will automatically
    increase and decrease the refcounter.

    powerpc/perf: Convert fsl_emb notifier to state machine callbacks

    Looks like fsl_emb was completely missed by commit 3f6da3905398 ("perf:

    So, apply same changes as commit 3f6da3905398 ("perf: Rework and fix
    the arch CPU-hotplug hooks") then commit 57ecde42cc74 ("powerpc/perf:

powerpc/powermac: Use early_* IO variants in via_calibrate_decr() [+ + +]

    powerpc/powermac: Use early_* IO variants in via_calibrate_decr()
    
    [ Upstream commit 86582e6189dd8f9f52c25d46c70fe5d111da6345 ]
    
    On a powermac platform, via the call path:
    
      start_kernel()
        time_init()
          ppc_md.calibrate_decr() (pmac_calibrate_decr)
            via_calibrate_decr()
    
    ioremap() and iounmap() are called. The unmap can enable interrupts
    unexpectedly (cond_resched() in vunmap_pmd_range()), which causes a
    warning later in the boot sequence in start_kernel().
    
    Use the early_* variants of these IO functions to prevent this.
    
    The issue is pre-existing, but is surfaced by commit 721255b9826b
    ("genirq: Use a maple tree for interrupt descriptor management").

powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPT [+ + +]

Date:   Wed Aug 23 15:53:17 2023 +1000

    powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPT
    
    [ Upstream commit eac030b22ea12cdfcbb2e941c21c03964403c63f ]
    
    lppaca_shared_proc() takes a pointer to the lppaca which is typically
    accessed through get_lppaca().  With DEBUG_PREEMPT enabled, this leads
    to checking if preemption is enabled, for example:
    
      BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693
      caller is lparcfg_data+0x408/0x19a0
      CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2
      Call Trace:
        dump_stack_lvl+0x154/0x200 (unreliable)
        check_preemption_disabled+0x214/0x220
        lparcfg_data+0x408/0x19a0
        ...
    
    This isn't actually a problem however, as it does not matter which
    lppaca is accessed, the shared proc state will be the same.
    vcpudispatch_stats_procfs_init() already works around this by disabling
    preemption, but the lparcfg code does not, erroring any time
    /proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled.
    
    Instead of disabling preemption on the caller side, rework
    lppaca_shared_proc() to not take a pointer and instead directly access
    the lppaca, bypassing any potential preemption checks.

    printk: ringbuffer: Fix truncating buffer size min_t cast
    
    commit 53e9e33ede37a247d926db5e4a9e56b55204e66c upstream.
    
    If an output buffer size exceeded U16_MAX, the min_t(u16, ...) cast in
    copy_data() was causing writes to truncate. This manifested as output
    bytes being skipped, seen as %NUL bytes in pstore dumps when the available
    record size was larger than 65536. Fix the cast to no longer truncate
    the calculation.

    procfs: block chmod on /proc/thread-self/comm
    
    commit ccf61486fe1e1a48e18c638d1813cda77b3c0737 upstream.
    
    Due to an oversight in commit 1b3044e39a89 ("procfs: fix pthread
    cross-thread naming if !PR_DUMPABLE") in switching from REG to NOD,
    chmod operations on /proc/thread-self/comm were no longer blocked as
    they are on almost all other procfs files.
    
    A very similar situation with /proc/self/environ was used to as a root
    exploit a long time ago, but procfs has SB_I_NOEXEC so this is simply a
    correctness issue.

    pstore/ram: Check start of empty przs during init
    
    commit fe8c3623ab06603eb760444a032d426542212021 upstream.
    
    After commit 30696378f68a ("pstore/ram: Do not treat empty buffers as
    valid"), initialization would assume a prz was valid after seeing that
    the buffer_size is zero (regardless of the buffer start position). This
    unchecked start value means it could be outside the bounds of the buffer,
    leading to future access panics when written to:
    
     sysdump_panic_event+0x3b4/0x5b8
     atomic_notifier_call_chain+0x54/0x90
     panic+0x1c8/0x42c
     die+0x29c/0x2a8
     die_kernel_fault+0x68/0x78
     __do_kernel_fault+0x1c4/0x1e0
     do_bad_area+0x40/0x100
     do_translation_fault+0x68/0x80
     do_mem_abort+0x68/0xf8
     el1_da+0x1c/0xc0

     ramoops_pstore_write+0x198/0x1e8
     pstore_console_write+0x94/0xe0
     ...
    
    To avoid this, also check if the prz start is 0 during the initialization
    phase. If not, the next prz sanity check case will discover it (start >
    size) and zap the buffer back to a sane state.

    quota: fix dqput() to follow the guarantees dquot_srcu should provide
    
    [ Upstream commit dabc8b20756601b9e1cc85a81d47d3f98ed4d13a ]
    
    The dquot_mark_dquot_dirty() using dquot references from the inode
    should be protected by dquot_srcu. quota_off code takes care to call
    synchronize_srcu(&dquot_srcu) to not drop dquot references while they
    are used by other users. But dquot_transfer() breaks this assumption.
    We call dquot_transfer() to drop the last reference of dquot and add
    it to free_dquots, but there may still be other users using the dquot
    at this time, as shown in the function graph below:
    
           cpu1              cpu2
    _________________|_________________
    wb_do_writeback         CHOWN(1)

        ...
         dquot_mark_dquot_dirty // try to dirty old quota
          test_bit(DQ_ACTIVE_B, &dquot->dq_flags) // still ACTIVE
          if (test_bit(DQ_MOD_B, &dquot->dq_flags))
          // test no dirty, wait dq_list_lock
                        ...
                         dquot_transfer
                          __dquot_transfer
                          dqput_all(transfer_from) // rls old dquot
                           dqput // last dqput
                            dquot_release
                             clear_bit(DQ_ACTIVE_B, &dquot->dq_flags)
                            atomic_dec(&dquot->dq_count)
                            put_dquot_last(dquot)
                             list_add_tail(&dquot->dq_free, &free_dquots)
                             // add the dquot to free_dquots
          if (!test_and_set_bit(DQ_MOD_B, &dquot->dq_flags))
            add dqi_dirty_list // add released dquot to dirty_list
    
    This can cause various issues, such as dquot being destroyed by
    dqcache_shrink_scan() after being added to free_dquots, which can trigger
    a UAF in dquot_mark_dquot_dirty(); or after dquot is added to free_dquots
    and then to dirty_list, it is added to free_dquots again after
    dquot_writeback_dquots() is executed, which causes the free_dquots list to
    be corrupted and triggers a UAF when dqcache_shrink_scan() is called for
    freeing dquot twice.
    
    As Honza said, we need to fix dquot_transfer() to follow the guarantees
    dquot_srcu should provide. But calling synchronize_srcu() directly from
    dquot_transfer() is too expensive (and mostly unnecessary). So we add
    dquot whose last reference should be dropped to the new global dquot
    list releasing_dquots, and then queue work item which would call
    synchronize_srcu() and after that perform the final cleanup of all the
    dquots on releasing_dquots.

    Now we have a helper function dquot_dirty() to determine if dquot has

rcu: dump vmalloc memory info safely [+ + +]

    rcu: dump vmalloc memory info safely
    
    commit c83ad36a18c02c0f51280b50272327807916987f upstream.
    
    Currently, for double invoke call_rcu(), will dump rcu_head objects memory
    info, if the objects is not allocated from the slab allocator, the
    vmalloc_dump_obj() will be invoke and the vmap_area_lock spinlock need to
    be held, since the call_rcu() can be invoked in interrupt context,
    therefore, there is a possibility of spinlock deadlock scenarios.
    
    And in Preempt-RT kernel, the rcutorture test also trigger the following
    lockdep warning:

    RDMA/efa: Fix wrong resources deallocation order
    
    [ Upstream commit dc202c57e9a1423aed528e4b8dc949509cd32191 ]
    
    When trying to destroy QP or CQ, we first decrease the refcount and
    potentially free memory regions allocated for the object and then
    request the device to destroy the object. If the device fails, the
    object isn't fully destroyed so the user/IB core can try to destroy the
    object again which will lead to underflow when trying to decrease an
    already zeroed refcount.
    
    Deallocate resources in reverse order of allocating them to safely free
    them.

RDMA/hns: Fix incorrect post-send with direct wqe of wr-list [+ + +]

    RDMA/hns: Fix incorrect post-send with direct wqe of wr-list
    
    [ Upstream commit 706efac4477cdb8be857f6322457de524acc02ff ]
    
    Currently, direct wqe is not supported for wr-list. RoCE driver excludes
    direct wqe for wr-list by judging whether the number of wr is 1.
    
    For a wr-list where the second wr is a length-error atomic wr, the
    post-send driver handles the first wr and adds 1 to the wr number counter
    firstly. While handling the second wr, the driver finds out a length error
    and terminates the wr handle process, remaining the counter at 1. This
    causes the driver mistakenly judges there is only 1 wr and thus enters
    the direct wqe process, carrying the current length-error atomic wqe.
    
    This patch fixes the error by adding a judgement whether the current wr
    is a bad wr. If so, use the normal doorbell process but not direct wqe
    despite the wr number is 1.

RDMA/irdma: Replace one-element array with flexible-array member [+ + +]
Author: Gustavo A. R. Silva <[email protected]>
Date:   Wed Aug 2 08:46:26 2023 -0600

    RDMA/irdma: Replace one-element array with flexible-array member
    
    [ Upstream commit 38313c6d2a02c28162e06753b01bd885caf9386d ]
    
    One-element and zero-length arrays are deprecated. So, replace
    one-element array in struct irdma_qvlist_info with flexible-array
    member.
    
    A patch for this was sent a while ago[1]. However, it seems that, at
    the time, the changes were partially folded[2][3], and the actual
    flexible-array transformation was omitted. This patch fixes that.
    
    The only binary difference seen before/after changes is shown below:
    
    |  drivers/infiniband/hw/irdma/hw.o
    | @@ -868,7 +868,7 @@
    | drivers/infiniband/hw/irdma/hw.c:484 (discriminator 2)

    |      55b:      imul   $0x45c,%rdi,%rdi

    |+     562:      add    $0x4,%rdi
    
    which is, of course, expected as it reflects the mistake made
    while folding the patch I've mentioned above.
    
    Worth mentioning is the fact that with this change we save 12 bytes
    of memory, as can be inferred from the diff snapshot above. Notice
    that:
    
    $ pahole -C rdma_qv_info idrivers/infiniband/hw/irdma/hw.o

    RDMA/rxe: Fix incomplete state save in rxe_requester
    
    [ Upstream commit 5d122db2ff80cd2aed4dcd630befb56b51ddf947 ]
    
    If a send packet is dropped by the IP layer in rxe_requester()
    the call to rxe_xmit_packet() can fail with err == -EAGAIN.
    To recover, the state of the wqe is restored to the state before
    the packet was sent so it can be resent. However, the routines
    that save and restore the state miss a significnt part of the
    variable state in the wqe, the dma struct which is used to process
    through the sge table. And, the state is not saved before the packet
    is built which modifies the dma struct.
    
    Under heavy stress testing with many QPs on a fast node sending
    large messages to a slow node dropped packets are observed and
    the resent packets are corrupted because the dma struct was not
    restored. This patch fixes this behavior and allows the test cases
    to succeed.

    [ Upstream commit b056327bee09e6b86683d3f709a438ccd6031d72 ]
    
    The siw_connect can go to err in below after cep is allocated successfully:
    
    1. If siw_cm_alloc_work returns failure. In this case socket is not
    assoicated with cep so siw_cep_put can't be called by siw_socket_disassoc.
    We need to call siw_cep_put twice since cep->kref is increased once after
    it was initialized.
    
    2. If siw_cm_queue_work can't find a work, which means siw_cep_get is not
    called in siw_cm_queue_work, so cep->kref is increased twice by siw_cep_get
    and when associate socket with cep after it was initialized. So we need to
    call siw_cep_put three times (one in siw_socket_disassoc).
    
    3. siw_send_mpareqrep returns error, this scenario is similar as 2.
    
    So we need to remove one siw_cep_put in the error path.

    RDMA/siw: Fabricate a GID on tun and loopback devices
    
    [ Upstream commit bad5b6e34ffbaacc77ad28a0f482e33b3929e635 ]
    
    LOOPBACK and NONE (tunnel) devices have all-zero MAC addresses.
    Currently, siw_device_create() falls back to copying the IB device's
    name in those cases, because an all-zero MAC address breaks the RDMA
    core address resolution mechanism.
    
    However, at the point when siw_device_create() constructs a GID, the
    ib_device::name field is uninitialized, leaving the MAC address to
    remain in an all-zero state.
    
    Fabricate a random artificial GID for such devices, and ensure this
    artificial GID is returned for all device query operations.

refscale: Fix uninitalized use of wait_queue_head_t [+ + +]

    refscale: Fix uninitalized use of wait_queue_head_t
    
    [ Upstream commit f5063e8948dad7f31adb007284a5d5038ae31bb8 ]
    
    Running the refscale test occasionally crashes the kernel with the
    following error:
    
    [ 8569.952896] BUG: unable to handle page fault for address: ffffffffffffffe8
    [ 8569.952900] #PF: supervisor read access in kernel mode

    [ 8569.952973]  </TASK>
    
    The likely cause is that init_waitqueue_head() is called after the call to
    the torture_create_kthread() function that creates the ref_scale_reader
    kthread.  Although this init_waitqueue_head() call will very likely
    complete before this kthread is created and starts running, it is
    possible that the calling kthread will be delayed between the calls to
    torture_create_kthread() and init_waitqueue_head().  In this case, the
    new kthread will use the waitqueue head before it is properly initialized,
    which is not good for the kernel's health and well-being.
    
    The above crash happened here:
    
            static inline void __add_wait_queue(...)
            {
                    :
                    if (!(wq->flags & WQ_FLAG_PRIORITY)) <=== Crash here
    
    The offset of flags from list_head entry in wait_queue_entry is
    -0x18. If reader_tasks[i].wq.head.next is NULL as allocated reader_task
    structure is zero initialized, the instruction will try to access address
    0xffffffffffffffe8, which is exactly the fault address listed above.
    
    This commit therefore invokes init_waitqueue_head() before creating
    the kthread.

    Revert "net: macsec: preserve ingress frame ordering"
    
    commit d3287e4038ca4f81e02067ab72d087af7224c68b upstream.
    
    This reverts commit ab046a5d4be4c90a3952a0eae75617b49c0cb01b.
    
    It was trying to work around an issue at the crypto layer by excluding
    ASYNC implementations of gcm(aes), because a bug in the AESNI version
    caused reordering when some requests bypassed the cryptd queue while
    older requests were still pending on the queue.
    
    This was fixed by commit 38b2f68b4264 ("crypto: aesni - Fix cryptd
    reordering problem on gcm"), which pre-dates ab046a5d4be4.
    
    Herbert Xu confirmed that all ASYNC implementations are expected to
    maintain the ordering of completions wrt requests, so we can use them
    in MACsec.
    
    On my test machine, this restores the performance of a single netperf
    instance, from 1.4Gbps to 4.4Gbps.

Revert "PCI: Mark NVIDIA T4 GPUs to avoid bus reset" [+ + +]
Author: Bjorn Helgaas <[email protected]>
Date:   Fri Sep 8 14:55:30 2023 -0500

    Revert "PCI: Mark NVIDIA T4 GPUs to avoid bus reset"
    
    commit 5260bd6d36c83c5b269c33baaaf8c78e520908b0 upstream.
    
    This reverts commit d5af729dc2071273f14cbb94abbc60608142fd83.
    
    d5af729dc207 ("PCI: Mark NVIDIA T4 GPUs to avoid bus reset") avoided
    Secondary Bus Reset on the T4 because the reset seemed to not work when the
    T4 was directly attached to a Root Port.
    
    But NVIDIA thinks the issue is probably related to some issue with the Root
    Port, not with the T4.  The T4 provides neither PM nor FLR reset, so
    masking bus reset compromises this device for assignment scenarios.
    
    Revert d5af729dc207 as requested by Wu Zongyong.  This will leave SBR
    broken in the specific configuration Wu tested, as it was in v6.5, so Wu
    will debug that further.

Revert "PCI: tegra194: Enable support for 256 Byte payload" [+ + +]
Author: Vidya Sagar <[email protected]>
Date:   Mon Jun 19 15:56:04 2023 +0530

    Revert "PCI: tegra194: Enable support for 256 Byte payload"
    
    commit ebfde1584d9f037b6309fc682c96e22dac7bcb7a upstream.
    
    After commit 4fb8e46c1bc4 ("PCI: tegra194: Enable support for 256 Byte
    payload"), we initialize MPS=256 for tegra194 Root Ports before enumerating
    the hierarchy.
    
    Consider an Endpoint that supports only MPS=128.  In the default situation
    (CONFIG_PCIE_BUS_DEFAULT set and no "pci=pcie_bus_*" parameter), Linux
    tries to configure the MPS of every device to match the upstream bridge.
    If the Endpoint is directly below the Root Port, Linux can reduce the Root
    Port MPS to 128 to match the Endpoint.  But if there's a switch in the
    middle, Linux doesn't reduce the Root Port MPS because other devices below
    the switch may already be configured with MPS larger than 128.
    
    This scenario results in uncorrectable Malformed TLP errors if the Root
    Port sends TLPs with payloads larger than 128 bytes.  These errors can
    be avoided by using the "pci=pcie_bus_safe" parameter, but it doesn't
    seem to be a good idea to always have this parameter even for basic
    functionality to work.
    
    Revert commit 4fb8e46c1bc4 ("PCI: tegra194: Enable support for 256 Byte
    payload") so the Root Ports default to MPS=128, which all devices
    support.
    
    If peer-to-peer DMA is not required, one can use "pci=pcie_bus_perf" to
    get the benefit of larger MPS settings.
