  • The pointers to user buffers are currently unsigned char *, which requires
    a lot of casting in the caller for any non-char typed buffers. Use void *
    instead.

  • EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4)
    Kernel panic - not syncing: EDAC MC0: Uncorrected Error (XEN) Domain 0 crashed: 'noreboot' set - not rebooting.

    This happens because FERR_NF_FBD bit 28 is not updated on i5000. Due to
    that, both bits 28 and 29 may be equal to one, returning channel = 3. As
    this value is invalid, EDAC core generates the panic.

  • The m68knommu coldfire pit clocksource looks like it was incorrectly
    marked as a continuous clocksource. Running with it marked as a
    continuous clocksource could cause hangs when the system switches to
    highres mode or enables nohz.

    This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
    clocksource. This will disallow systems using this clocksource from
    entering oneshot mode (disabling highres timers and nohz).

  • When I try to use markup_oops.pl in x86, I always get:

    cat 1 | perl markup_oops.pl ./vmlinux
    objdump: --start-address: bad number: NaN
    No matching code found

    This is because in line:
    if ($line =~ /EIP is at ([a-zA-Z0-9\_]+)\+0x([0-9a-f]+)\/[a-f0-9]/) {
    $function = $1;
    $func_offset = $2;
    }

    $func_offset will get a number like "0x2"

    But in follow code:

    my $decodestart = Math::BigInt->from_hex("0x$target") -
    Math::BigInt->from_hex("0x$func_offset");

    It add other ox to ox2. Then this value will be set to NaN.

    So I made a small patch to fix it.

  • inotify will WARN() if it finds that the idr and the fsnotify internals

  • Since commit 7e790dd5fc937bc8d2400c30a05e32a9e9eef276 ("inotify: fix
    error paths in inotify_update_watch") inotify changed the manor in which
    it gave watch descriptors back to userspace. Previous to this commit
    inotify acted like the following:

    inotify_add_watch(X, Y, Z) = 1
    inotify_rm_watch(X, 1);
    inotify_add_watch(X, Y, Z) = 2

    but after this patch inotify would return watch descriptors like so:

    inotify_add_watch(X, Y, Z) = 1
    inotify_rm_watch(X, 1);
    inotify_add_watch(X, Y, Z) = 1

    which I saw as equivalent to opening an fd where

    open(file) = 1;
    close(1);
    open(file) = 1;

    seemed perfectly reasonable. The issue is that quite a bit of userspace
    apparently relies on the behavior in which watch descriptors will not be
    quickly reused. KDE relies on it, I know some selinux packages rely on
    it, and I have heard complaints from other random sources such as debian
    bug 558981.

    Although the man page implies what we do is ok, we broke userspace so
    this patch almost reverts us to the old behavior. It is still slightly
    racey and I have patches that would fix that, but they are rather large
    and this will fix it for all real world cases. The race is as follows:

    - task1 creates a watch and blocks in idr_new_watch() before it updates
    the hint.
    - task2 creates a watch and updates the hint.
    - task1 updates the hint with it's older wd
    - task removes the watch created by task2
    - task adds a new watch and will reuse the wd originally given to task2

    it requires moving some locking around the hint (last_wd) but this should
    solve it for the real world and be -stable safe.

    As a side effect this patch papers over a bug in the lib/idr code which
    is causing a large number WARN's to pop on people's system and many
    reports in kerneloops.org. I'm working on the root cause of that idr
    bug seperately but this should make inotify immune to that issue.

    which made one 1600x900 eDP panel's mode check invalid because of overclock,
    but actually this 6bpc panel does can work with x1 lane at 2.7G. This one
    trys to take bpp value properly both in mode validation and mode setting.

  • Many platform support this feature, and it can provide significant
    power savings when the reduced refresh rate is low. However, on some
    platforms a secondary (reduced) timing is provided but not actually
    supported by the hardware. This results in undesirable flicker at
    runtime.

    So disable the feature by default, but allow users to opt-in to the
    reduced clock behavior with a new module parameter, lvds_downclock,
    that can be set to 1 to enable the feature.

  • This fixes CERT-FI FICORA #341748

    Discovered by Olli Jarva and Tuomo Untinen from the CROSS
    project at Codenomicon Ltd.

    Just like in CVE-2007-4567, we can't rely upon skb_dst() being
    non-NULL at this point. We fixed that in commit
    e76b2b2567b83448c2ee85a896433b96150c92e6 ("[IPV6]: Do no rely on
    skb->dst before it is assigned.")

    However commit 483a47d2fe794328d29950fe00ce26dd405d9437 ("ipv6: added
    net argument to IP6_INC_STATS_BH") put a new version of the same bug
    into this function.

    Complicating analysis further, this bug can only trigger when network
    namespaces are enabled in the build. When namespaces are turned off,
    the dev_net() does not evaluate it's argument, so the dereference
    would not occur.

    So, for a long time, namespaces couldn't be turned on unless SYSFS was
    disabled. Therefore, this code has largely been disabled except by
    people turning it on explicitly for namespace development.
