  • 524e525fa   staging: greybus: audio: fix uninitialized value issue ... Browse Code »

    commit 1dffeb8b8b4c261c45416d53c75ea51e6ece1770 upstream.

    The current implementation for gbcodec_mixer_dapm_ctl_put() uses
    uninitialized gbvalue for comparison with updated value. This was found
    using static analysis with coverity.

    Uninitialized scalar variable (UNINIT)
    11. uninit_use: Using uninitialized value
    gbvalue.value.integer_value[0].
    460 if (gbvalue.value.integer_value[0] != val) {

    This patch fixes the issue with fetching the gbvalue before using it for
    comparision.

    commit fea22e159d51c766ba70473f473a0ec914cc7e92 upstream.

    let's use usb_find_common_endpoints() to discover endpoints, it does all
    necessary checks for type and xfer direction

    remove memset() in hfa384x_create(), because we now assign endpoints in
    prism2sta_probe_usb() and because create_wlan() uses kzalloc() to
    allocate hfa384x struct before calling hfa384x_create()

    Fix pyeiq can't detect camera device when build imx8-media-dev.c as
    modules. Video device will be registered before entities link setup
    and it will send an event to userspace once video device created.
    Userspace will try to open the video device but entities links are
    still not established due to driver need to wait all subdev register,
    so driver will return -ENODEV, it leads to pyeiq fail. The patch add
    checking for entities link when userspace try to open video device and
    will return directly when links are not ready.

  • 2698fab03   staging: rtl8192u: fix a dubious looking mask before a shift ... Browse Code »

    [ Upstream commit c4283950a9a4d3bf4a3f362e406c80ab14f10714 ]

    Currently the masking of ret with 0xff and followed by a right shift
    of 8 bits always leaves a zero result. It appears the mask of 0xff
    is incorrect and should be 0xff00, but I don't have the hardware to
    test this. Fix this to mask the upper 8 bits before shifting.

    commit 11536442a3b4e1de6890ea5e805908debb74f94a upstream.

    The variable authmode can be uninitialized. The danger would be if
    it equals to _WPA_IE_ID_ (0xdd) or _WPA2_IE_ID_ (0x33). We can avoid
    this by setting it to zero instead. This is the approach that was
    used in the rtl8723bs driver.

  • 6a7626c47   staging: android: ashmem: Fix lockdep warning for write operation ... Browse Code »

    commit 3e338d3c95c735dc3265a86016bb4c022ec7cadc upstream.

    syzbot report [1] describes a deadlock when write operation against an
    ashmem fd executed at the time when ashmem is shrinking its cache results
    in the following lock sequence:

    Possible unsafe locking scenario:

    CPU0 CPU1
    ---- ----
    lock(fs_reclaim);
    lock(&sb->s_type->i_mutex_key#13);
    lock(fs_reclaim);
    lock(&sb->s_type->i_mutex_key#13);

    kswapd takes fs_reclaim and then inode_lock while generic_perform_write
    takes inode_lock and then fs_reclaim. However ashmem does not support
    writing into backing shmem with a write syscall. The only way to change
    its content is to mmap it and operate on mapped memory. Therefore the race
    that lockdep is warning about is not valid. Resolve this by introducing a
    separate lockdep class for the backing shmem inodes.
