[Ksplice][Fedora-18-updates] New updates available via Ksplice (FEDORA-2013-13536)

[Phil Turnbull]

Synopsis: FEDORA-2013-13536 can now be patched using Ksplice

Systems running Fedora 18 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2013-13536.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 18 install
these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Deadlock in CIFS file reopening.

Incorrect locking in the CIFS filesystem can cause a deadlock when attempting to
repoen a file for reading or writing on a CIFS filesystem .


* Data corruption in ext4 filesystem online resizing.

For ext4 filesystems with block sizes equal to 1K, an invalid calculation when
backing up data during an online resize can cause file system corruption.


* NULL pointer dereference in XHCI container allocation.

A missing error check when allocating DMA memory for a XHCI container can cause
a NULL pointer dereference and kernel panic.


* Race condition in cgroup event removal.

Incorrect reference counting when removing a cgroup event while the cgroup is
being unmounting can trigger a BUG_ON and kernel panic.


* Use-after-free in cgroup memory error path.

A reference counting error when bringing a memory control group online can trigger
a use-after-free condition and cause a kernel panic.


* Kernel crash in OCFS inline extended attributes with reflinked files.

Incorrect allocation sizes for inline extended attributes during reflink
could result in a kernel BUG() and subsequent crash.
