[PATCH] readv/writev syscalls are not checked by lsm
it seems that readv(2)/writev(2) syscalls do not call
file_permission callback. Looks like this is overlook.
I have filled the issue into redhat bugzilla as
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169433
and got the recommendation to post this on lsm mailing list.
The following trivial patch solves the problem.

[PATCH] Keys: Add possessor permissions to keys [try #3]
The attached patch adds extra permission grants to keys for the possessor of a
key in addition to the owner, group and other permissions bits. This makes
SUID binaries easier to support without going as far as labelling keys and key
targets using the LSM facilities.
This patch adds a second "pointer type" to key structures (struct key_ref *)
that can have the bottom bit of the address set to indicate the possession of
a key. This is propagated through searches from the keyring to the discovered
key. It has been made a separate type so that the compiler can spot attempts
to dereference a potentially incorrect pointer.
The "possession" attribute can't be attached to a key structure directly as
it's not an intrinsic property of a key.
Pointers to keys have been replaced with struct key_ref *'s wherever
possession information needs to be passed through.
This does assume that the bottom bit of the pointer will always be zero on
return from kmem_cache_alloc().
The key reference type has been made into a typedef so that at least it can be
located in the sources, even though it's basically a pointer to an undefined
type. I've also renamed the accessor functions to be more useful, and all
reference variables should now end in "_ref".

While the queue_if_no_path variable is correctly set to 1, the

the option *always* gets turned off.

[APPLETALK]: Fix broadcast bug.
From: Oliver Dawid <oliver@helios.de>
we found a bug in net/appletalk/ddp.c concerning broadcast packets. In
kernel 2.4 it was working fine. The bug first occured 4 years ago when
switching to new SNAP layer handling. This bug can be splitted up into a
sending(1) and reception(2) problem:
Sending(1)
In kernel 2.4 broadcast packets were sent to a matching ethernet device
and atalk_rcv() was called to receive it as "loopback" (so loopback
packets were shortcutted and handled in DDP layer).
When switching to the new SNAP structure, this shortcut was removed and
the loopback packet was send to SNAP layer. The author forgot to replace
the remote device pointer by the loopback device pointer before sending
the packet to SNAP layer (by calling ddp_dl->request() ) therfor the
packet was not sent back by underlying layers to ddp's atalk_rcv().
Reception(2)
In atalk_rcv() a packet received by this loopback mechanism contains now
the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong)
remote ethernet device pointer) and therefor no matching socket will be
found to deliver this packet to. Because a broadcast packet should be
send to the first matching socket (as it is done in many other protocols
(?)), we removed the network comparison in broadcast case.
Below you will find a patch to correct this bug. Its diffed to kernel

[NET]: Fix module reference counts for loadable protocol modules
I have been experimenting with loadable protocol modules, and ran into
several issues with module reference counting.
The first issue was that __module_get failed at the BUG_ON check at
the top of the routine (checking that my module reference count was
not zero) when I created the first socket. When sk_alloc() is called,
my module reference count was still 0. When I looked at why sctp
didn't have this problem, I discovered that sctp creates a control
socket during module init (when the module ref count is not 0), which
keeps the reference count non-zero. This section has been updated to
address the point Stephen raised about checking the return value of
try_module_get().
The next problem arose when my socket init routine returned an error.
This resulted in my module reference count being decremented below 0.
My socket ops->release routine was also being called. The issue here
is that sock_release() calls the ops->release routine and decrements
the ref count if sock->ops is not NULL. Since the socket probably
didn't get correctly initialized, this should not be done, so we will
set sock->ops to NULL because we will not call try_module_get().
While searching for another bug, I also noticed that sys_accept() has
a possibility of doing a module_put() when it did not do an
__module_get so I re-ordered the call to security_socket_accept().

[IB] uverbs: Close some exploitable races
Al Viro pointed out that the current IB userspace verbs interface
allows userspace to cause mischief by closing file descriptors before
we're ready, or issuing the same command twice at the same time. This
patch closes those races, and fixes other obvious problems such as a
module reference leak.
Some other interface bogosities will require an ABI change to fix
properly, so I'm deferring those fixes until 2.6.15.

[ARM] 2936/1: ixp4xx default config fixes
Patch from Vincent Sanders
A recent patch which made IXP4xx mach_desc's depend on config options
had the effect of not building the kernel for several machines it
possibly could be, this patch updates the default config to ensure all
possible machines are built for by default.
