Systems running Ubuntu 12.10 Quantal can now use Ksplice to patch
against the latest Ubuntu kernel update, 3.5.0-17.29.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 12.10 Quantal
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

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Deadlock in VFS file renaming.

A deadlock can be triggered in the VFS subsystem when multiple processes
attempt to rename the same file.


* Integer overflow in Verity block driver.

A malformed Verity volume can trigger an integer overflow when
being mounted.


* Deadlock in TTY driver.

Invalid locking in the kernel can cause a deadlock when a process attempts
to query the state of the keyboard LEDs.


* Kernel panic in TTY driver.

An invalid assumption in the TTY driver can lead to a kernel
panic (BUG_ON) when reading data from a TTY using the normal
line discipline.


* Kernel panic in Broadcom 43xx wireless driver.

A kernel panic can be triggered when unloading the legacy
Broadcom wireless driver when no firmware is present.


* Kernel panic in coredumping.

An unprivileged user can cause a double-free when constructing a
coredump under low-memory conditions.


* Use-after-free in IP over Infiniband.

A use-after-condition condition can be triggered when processing
multicast IP packets over an Infiniband device.


* Use-after-free in Infiniband RDMA driver.

A use-after-free condition triggered in the Infiniband RDMA driver
when resetting an Infiniband device.


* Deadlock in page unmapping.

Invalid locking in the memory management subsystem can cause a deadlock
and kernel hang when unmapping pages from a process' address space.


* Use-after-free in DRM CRTC.
