And then we are stuck in the subsequent 'while' loop. We need an explicit cast.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you are using a 64-bit kernel with 32-bit userland, then scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc with -mcmodel=kernel, which produces: <stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode and trips the "broken compiler" test at arch/x86/Makefile:120.

This, unfortunately has the side effect of changing the args->valuelen parameter in cases where it shouldn't. That is, when we replace a remote attribute, the incoming replacement stores the value and length in args->value and args->valuelen, but then the lookup which finds the existing remote attribute overwrites args->valuelen with the length of the remote attribute being replaced. Hence when we go to create the new attribute, we create it of the size of the existing remote attribute, not the size it is supposed to be. When the new attribute is much smaller than the old attribute, this results in a transaction overrun and an ASSERT() failure on a debug kernel: XFS: Assertion failed: tp->t_blk_res_used <= tp->t_blk_res, file: fs/xfs/xfs_trans.c, line: 331 Fix this by keeping the remote attribute value length separate to the attribute value length in the xfs_da_args structure. The enables us to pass the length of the remote attribute to be removed without overwriting the new attribute's length. Also, ensure that when we save remote block contexts for a later rename we zero the original state variables so that we don't confuse the state of the attribute to be removes with the state of the new attribute that we just added.

Doing so within xfs_vn_tmpfile() makes it roughly equivalent to xfs_vn_mknod(), which is already used as a common create handler. xfs_vn_mknod() does not currently have a mechanism to determine whether to link the file into the namespace. Therefore, further abstract xfs_vn_mknod() into a new xfs_generic_create() handler with a tmpfile parameter. This new handler calls xfs_create_tmpfile() and d_tmpfile() on the dentry when called via ->tmpfile().

The first is a long standing bug that causes bogus data to show up in the refcnt field of the module_refcnt tracepoint. It was introduced by a merge conflict resolution back in 2.6.35-rc days. The result should be 'refcnt = incs - decs', but instead it did 'refcnt = incs + decs'. The second fix is to a bug that was introduced in this merge window that allowed for a tracepoint funcs pointer to be used after it was freed. Moving the location of where the probes are released solved the problem" * tag 'trace-fixes-v3.15-rc4-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracepoint: Fix use of tracepoint funcs after rcu free trace: module: Maintain a valid user count

There is a race window where tracepoints (RCU readers) can perform a "use-after-grace-period-after-free", which shows up as a GPF in stress-tests.

Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.

We've been unable to find a way to identify touchpads where setting the bit will fail, so this patch uses a dmi based blacklist for this. https://bugzilla.kernel.org/show_bug.cgi?id=61151 Cc: stable@vger.kernel.org Reported-by: Philipp Wolfer <ph.wolfer@gmail.com> Tested-by: Philipp Wolfer <ph.wolfer@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

This is because setting the count was moved after the CA value is determined, which is only after the monitor_present check in hdmi_setup_audio_infoframe(). Unfortunately, in some cases, such as with a non-spec-compliant codec or with a problematic video driver, monitor_present is always 0. As a specific example, this seems to happen with gen1 ATV (SiI1390 codec), causing left-channel-only stereo playback (multi-channel playback has apparently never worked with this codec despite it reporting 8 channels, reason unknown). Simply setting converter channel count without setting the pin infoframe and channel mapping as well does not theoretically make much sense as this will just mean they are out-of-sync and multichannel playback will have a wrong channel mapping. However, adding back just setting the converter channel count even in no-monitor case is the safest change which at least fixes the stereo playback regression on SiI1390 codec. Do that.
