--- Exception: c01 (System Call) at 00000080da560cfc

The root cause was an EEH error, which sent us down the offload_close path in
the cxgb3 driver, which in turn sets cdev->l2opt to NULL, without regard for
upper layer driver (like the cxgbi drivers) which might have execution contexts
in the middle of its use. The result is the oops above, when t3_l2t_get attempts
to dereference L2DATA(cdev)->nentries in arp_hash right after the EEH error handler sets it to NULL.

The fix is to prevent the setting of the NULL pointer until after there are no
further users of it.  The t3cdev->l2opt pointer is now converted to be an rcu
pointer and the L2DATA macro is now called under the protection of the
rcu_read_lock().  When the EEH error path:
t3_adapter_error->offload_close->cxgb3_offload_deactivate
Is exectured, setting of that l2opt pointer to NULL, is now gated on an rcu
quiescence point, preventing, allowing L2DATA callers to safely check for a NULL
pointer without concern that the underlying data will be freeded before the
pointer is dereferenced.

This has been tested by the reporter and shown to fix the reproted oops

Note: I had attempted to post a fix for this bug previously.  While it solved
the issue, James B. pointed out that it really didn't make much sense, and on
closer inspection I agree. Some internal structures to this affected pointer are
already refcounted and so all we should need to do is prevent the race that
arises between the reading of the affected pointer and its setting to NULL.

13 years ago[SCSI] libsas: fix failure to revalidate domain for anything but the first expander...
Mark Salyzyn [Thu, 1 Sep 2011 13:11:17 +0000 (06:11 -0700)]
[SCSI] libsas: fix failure to revalidate domain for anything but the first expander child.

In an enclosure model where there are chaining expanders to a large body
of storage, it was discovered that libsas, responding to a broadcast
event change, would only revalidate the domain of first child expander
in the list.

The issue is that the pointer value to the discovered source device was
used to break out of the loop, rather than the content of the pointer.

This still remains non-compliant as the revalidate domain code is
supposed to loop through all child expanders, and not stop at the first
one it finds that reports a change count. However, the design of this
routine does not allow multiple device discoveries and that would be a
more complicated set of patches reserved for another day. We are fixing
the glaring bug rather than refactoring the code.

XZ: Fix incorrect XZ_BUF_ERROR

xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the
following was true:

 - The caller knows how many bytes of output to expect and only provides
   that much output space.

 - When the last output bytes are decoded, the caller-provided input
   buffer ends right before the LZMA2 end of payload marker.  So LZMA2
   won't provide more output anymore, but it won't know it yet and thus
   won't return XZ_STREAM_END yet.

 - A BCJ filter is in use and it hasn't left any unfiltered bytes in the
   temp buffer.  This can happen with any BCJ filter, but in practice
   it's more likely with filters other than the x86 BCJ.

This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where
Squashfs thinks that a valid file system is corrupt.

This also fixes a similar bug in single-call mode where the uncompressed
size of a block using BCJ + LZMA2 was 0 bytes and caller provided no
output space.  Many empty .xz files don't contain any blocks and thus
don't trigger this bug.

This also tweaks a closely related detail: xz_dec_bcj_run() could call
xz_dec_lzma2_run() to decode into temp buffer when it was known to be
useless.  This was harmless although it wasted a minuscule number of CPU
cycles.

    interruptible waits to wait for synchronous
    commands and firmware loading.

    This leads to "interesting" bugs, because it
    can't actually handle the interruptions; for
    example when a command sending is interrupted
    it will assume the command completed fully,
    and then leave it pending, which leads to all
    kinds of trouble when the command finishes
    later.

    Since there's no easy way to gracefully deal
    with interruptions, fix the driver to not use
    interruptible waits.

    This at least fixes the error

MIPS: PM: Use struct syscore_ops instead of sysdevs for PM (v2)

Convert some MIPS architecture's code to using struct syscore_ops
objects for power management instead of sysdev classes and sysdevs.

This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.
