Commit 48b32a3553a54740d236b79a90f20147a25875e3 ("reiserfs: use generic
xattr handlers") introduced a problem that causes corruption when extended
attributes are replaced with a smaller value.The issue is that the reiserfs_setattr to shrink the xattr file was moved
from before the write to after the write.The root issue has always been in the reiserfs xattr code, but was papered
over by the fact that in the shrink case, the file would just be expanded
again while the xattr was written.The end result is that the last 8 bytes of xattr data are lost.
This patch fixes it to use new_size.

Commit 677c9b2e393a0cd203bd54e9c18b012b2c73305a ("reiserfs: remove
privroot hiding in lookup") removed the magic from the lookup code to hide
the .reiserfs_priv directory since it was getting loaded at mount-time
instead. The intent was that the entry would be hidden from the user via
a poisoned d_compare, but this was faulty.This introduced a security issue where unprivileged users could access and
modify extended attributes or ACLs belonging to other users, including
root.This patch resolves the issue by properly hiding .reiserfs_priv. This was
the intent of the xattr poisoning code, but it appears to have never
worked as expected. This is fixed by using d_revalidate instead of
d_compare.This patch makes -oexpose_privroot a no-op. I'm fine leaving it this way.
The effort involved in working out the corner cases wrt permissions and
caching outweigh the benefit of the feature.Signed-off-by: Jeff Mahoney

My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was
testing a whole set of patches together and missed a conversion to the
new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake
965 class chips. Fortunately, the fix is trivial and has been tested.Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or
we'll end up reading the wrong graphics memory, likely causing hangs,
crashes, or worse.Reported-by: Zdenek Kabelac

This patch (as1370) fixes a bug in the USB runtime power management
code. When a driver claims an interface, it doesn't expect to need to
call usb_autopm_get_interface() or usb_autopm_put_interface() for
runtime PM to work. Runtime PM can be controlled by the driver's
primary interface; the additional interfaces it claims shouldn't
interfere. As things stand, the claimed interfaces will prevent the
device from autosuspending.To fix this problem, the patch sets interfaces to the suspended state
when they are claimed.Also, although in theory this shouldn't matter, the patch changes the
suspend code so that interfaces are suspended in reverse order from
detection and resuming. This is how the PM core works, and we ought
to use the same approach.Signed-off-by: Alan Stern

This patch (as1369) fixes a problem in ehci-hcd. Some controllers

reclamation: Completed siTDs are stored on a list and not reused until
at least one frame has passed.Signed-off-by: Alan Stern

This patch (as1363) changes the way USB remote wakeup is handled
during system sleeps. It won't be enabled unless an interface driver
specifically needs it. Also, it won't be enabled during the FREEZE or
QUIESCE phases of hibernation, when the system doesn't respond to
wakeup events anyway. Finally, if the device is already
runtime-suspended with remote wakeup enabled, but wakeup is supposed
to be disabled for the system sleep, the device gets woken up so that
it can be suspended again with the proper wakeup setting.This will fix problems people have reported with certain USB webcams
that generate wakeup requests when they shouldn't, and as a result
cause system suspends to fail. Seehttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/515109
