14 years agofutex: futex_find_get_task remove credentails check
Michal Hocko [Wed, 30 Jun 2010 07:51:19 +0000 (09:51 +0200)]
futex: futex_find_get_task remove credentails check

futex_find_get_task is currently used (through lookup_pi_state) from two
contexts, futex_requeue and futex_lock_pi_atomic.  None of the paths
looks it needs the credentials check, though.  Different (e)uids
shouldn't matter at all because the only thing that is important for
shared futex is the accessibility of the shared memory.

The credentail check results in glibc assert failure or process hang (if
glibc is compiled without assert support) for shared robust pthread
mutex with priority inheritance if a process tries to lock already held
lock owned by a process with a different euid:

pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed.

The problem is that futex_lock_pi_atomic which is called when we try to
lock already held lock checks the current holder (tid is stored in the
futex value) to get the PI state.  It uses lookup_pi_state which in turn
gets task struct from futex_find_get_task.  ESRCH is returned either
when the task is not found or if credentials check fails.

futex_lock_pi_atomic simply returns if it gets ESRCH.  glibc code,
however, doesn't expect that robust lock returns with ESRCH because it
should get either success or owner died.

USB: gadget: f_mass_storage: stale common->fsg value bug fix

On fsg_unbind the common->fsg pointer was not NULLed if the
unbound fsg_dev instance was the current one.  As an effect,
the incorrect pointer was preserved in all further operations
which caused do_set_interface to reference an invalid region.

This commit fixes this by raising an exception in fsg_bind
which will change the common->fsg pointer.  This also requires
an wait queue so that the thread in fsg_bind can wait till the

This commit removes also a config and new_config fields of
fsg_common as they are no longer needed since fsg can be
used to determine whether function is active or not.

Moreover, this commit removes possible race condition where
the fsg field was modified in both the worker thread and
form various other contexts.  This is fixed by replacing
prev_fsg with new_fsg.  At this point, fsg is assigned only

USB: obey the sysfs power/wakeup setting

This patch (as1403) is a partial reversion of an earlier change
(commit 5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep").  After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.

Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button.  Such a
device should be allowed to do its job.

The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline).  The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default.  Hence this reversion will not
re-introduce any old problems.

Sarah Sharp [Thu, 10 Jun 2010 19:25:28 +0000 (12:25 -0700)]
USB: xHCI: Fix bug in link TRB activation change.

Commit 6c12db90f19727c76990e7f4801c67a148b30111 introduced a bug for
control transfers.  The patch was supposed to change when the link TRBs at
the end of each ring segment were given to the hardware.  If a transfer
descriptor (TD) ended just before the link TRB, the code wouldn't give
back the link TRB to the hardware; instead it would be given back in
prepare_ring() just before the next TD was enqueued at the top of the
ring.

Unfortunately, the code relied on checking the chain bit of the TRB to
determine whether the TD ended just before the link TRB.  It assumed that
the ring enqueuing code would call prepare_ring() before enqueuing the
next TD.  However, control transfers are made of multiple TDs, and
prepare_ring() is only called once before enqueuing two or three TDs.

If the first or second TD of the control transfer ended just before the
link TRB, then the code in inc_enq() would not move the enqueue pointer
past the link TRB, and the link TRB would get overwritten.  This would
cause the xHCI driver to start writing to memory past the ring segment,
and eventually the system would crash or hang.

The fix is to add a flag to inc_enq() that says whether the caller will
enqueue more TDs before calling prepare_ring().  If the chain bit is
cleared (meaning this is the last TRB in a TD), and the caller will not
enqueue more TDs, then we defer giving back the link TRB.

14 years agoipmi: make sure drivers were registered before unregistering them

ipmi: make sure drivers were registered before unregistering them

The ipmi code will never register a PCI or Open Firmware driver if a
hardcoded device is provided by the user by providing device addresses via
the module parameters.  This can cause us to attempt to unregister a
driver that was never registered, resulting in an oops.  Keep track of
registration in order to avoid this.

Fixes a post-2.6.34 regression.

14 years agokexec: fix Oops in crash_shrink_memory()
Pavan Naregundi [Tue, 29 Jun 2010 22:05:28 +0000 (15:05 -0700)]
kexec: fix Oops in crash_shrink_memory()

When crashkernel is not enabled, "echo 0 > /sys/kernel/kexec_crash_size"
OOPSes the kernel in crash_shrink_memory.  This happens when
crash_shrink_memory tries to release the 'crashk_res' resource which are
not reserved.  Also value of "/sys/kernel/kexec_crash_size" shows as 1,
which should be 0.

This patch fixes the OOPS in crash_shrink_memory and shows
"/sys/kernel/kexec_crash_size" as 0 when crash kernel memory is not
reserved.
