The security hooks to check permissions to remove an xfrm_policy were
actually done after the policy was removed. Since the unlinking and
deletion are done in xfrm_policy_by* functions this moves the hooks
inside those 2 functions. There we have all the information needed to
do the security check and it can be done before the deletion. Since
auditing requires the result of that security check err has to be passed
back and forth from the xfrm_policy_by* functions.
This patch also fixes a bug where a deletion that failed the security
check could cause improper accounting on the xfrm_policy
(xfrm_get_policy didn't have a put on the exit path for the hold taken
by xfrm_policy_by*)
It also fixes the return code when no policy is found in
xfrm_add_pol_expire. In old code (at least back in the 2.6.18 days) err
wasn't used before the return when no policy is found and so the
initialization would cause err to be ENOENT. But since err has since
been used above when we don't get a policy back from the xfrm_policy_by*
function we would always return 0 instead of the intended ENOENT. Also
fixed some white space damage in the same area.

[GFS2] fix hangup when multiple processes are trying to write to the same file
This fixes a problem I encountered while running bonnie++. When you have one
thread that opens a file and starts to write to it, and then another thread that
tries to open and write to the same file, the second thread will loop forever
trying to grab the inode lock for that inode. Basically we come in through
generic_buffered_file_write, which calls gfs2_prepare_write, which then attempts
to grab the glock. Because we don't own the lock, gfs2_prepare_write gets
GLR_TRYFAILED, which returns AOP_TRUNCATED_PAGE to generic_buffered_file_write.
At this point generic_buffered_file_write loops around again and immediately
retries the prepare_write. This means that the second process never gets off of
the processor in order to allow the process that holds the lock to finish its
work and let go of the lock. This patch makes gfs2_glock_nq schedule() if it
gets back a GLR_TRYFAILED, which resolves this problem.

[PATCH] Fix buffer overflow in Omnikey CardMan 4040 driver (CVE-2007-0005)
Based on a patch from Don Howard <dhoward@redhat.com>
When calling write() with a buffer larger than 512 bytes, the
driver's write buffer overflows, allowing to overwrite the EIP and
execute arbitrary code with kernel privileges.
In read(), there exists a similar problem, but coming from the device.
A malicous or buggy device sending more than 512 bytes can overflow
of the driver's read buffer, with the same effects as above.
sysfs_write_file downs buffer->sem while calling flush_write_buffer, and
flushing that particular write buffer entails downing buffer->sem in
orphan_all_buffers, resulting in the obvious self-deadlock.

[IA64] kexec: Use EFI_LOADER_DATA for ELF core header
The address where the ELF core header is stored is passed to the secondary
kernel as a kernel command line option. The memory area for this header is
also marked as a separate EFI memory descriptor on ia64.
The separate EFI memory descriptor is at the moment of the type
EFI_UNUSABLE_MEMORY. With such a type the secondary kernel skips over the
entire memory granule (config option, 16M or 64M) when detecting memory.
If we are lucky we will just lose some memory, but if we happen to have
data in the same granule (such as an initramfs image), then this data will
never get mapped and the kernel bombs out when trying to access it.
So this is an attempt to fix this by changing the EFI memory descriptor
type into EFI_LOADER_DATA. This type is the same type used for the kernel
data and for initramfs. In the secondary kernel we then handle the ELF
core header data the same way as we handle the initramfs image.
This patch contains the kernel changes to make this happen. Pretty
straightforward, we reserve the area in reserve_memory(). The address for
the area comes from the kernel command line and the size comes from the
specialized EFI parsing function vmcore_find_descriptor_size().
The kexec-tools-testing code for this can be found here:

[DCCP]: Correctly split CCID half connections
This fixes a bug caused by a previous patch, which causes DCCP servers in
LISTEN state to not receive packets.
This patch changes the logic so that
* servers in either LISTEN or OPEN state get the RX half connection packets
* clients in OPEN state get the TX half connection packets

A backlog value of N really does mean allow "N + 1" connections
to queue to a listening socket. This allows one to specify
"0" as the backlog and still get 1 connection.

[PATCH] knfsd: provide sunrpc pool_mode module option
Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to
choose the mode for mapping NFS thread service pools to CPUs. Values are:
auto choose a mapping mode heuristically
global (default, same as the pre-2.6.19 code) a single global pool
percpu one pool per CPU
pernode one pool per NUMA node
Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch
makes the default "global".
The pool mode can be changed after boot/modprobe using /sys, if the NFS and
lockd services have been shut down. A useful side effect of this change is to
fix a small memory leak when unloading the module.

[PATCH] knfsd: fix recently introduced problem with shutting down a busy NFS server
When the last thread of nfsd exits, it shuts down all related sockets. It
currently uses svc_close_socket to do this, but that only is immediately
effective if the socket is not SK_BUSY.
If the socket is busy - i.e. if a request has arrived that has not yet been
processes - svc_close_socket is not effective and the shutdown process spins.
So create a new svc_force_close_socket which removes the SK_BUSY flag is set
and then calls svc_close_socket.
Also change some open-codes loops in svc_destroy to use
list_for_each_entry_safe.

[PATCH] knfsd: use recv_msg to get peer address for NFSD instead of code-copying
The sunrpc server code needs to know the source and destination address for
UDP packets so it can reply properly. It currently copies code out of the
network stack to pick the pieces out of the skb. This is ugly and causes
compile problems with the IPv6 stuff.
So, rip that out and use recv_msg instead. This is a much cleaner interface,
but has a slight cost in that the checksum is now checked before the copy, so
we don't benefit from doing both at the same time. This can probably be
fixed.
