net/netrom: Fix socket locking

2009-04-27T17:36:57+00:00

upstream commit: cc29c70dd581f85ee7a3e7980fb031f90b90a2ab

Patch "af_rose/x25: Sanity check the maximum user frame size"
(commit 83e0bbcbe2145f160fbaa109b0439dae7f4a38a9) from Alan Cox got
locking wrong. If we bail out due to user frame size being too large,
we must unlock the socket beforehand.

upstream commit: 83e0bbcbe2145f160fbaa109b0439dae7f4a38a9

CVE-2009-0795.

Otherwise we can wrap the sizes and end up sending garbage.

Closes #10423

Fixed trivial IPv4/6 address printing conflicts in fs/cifs/connect.c due
to the conversion to %pI (in this networking merge) and the addition of
doing IPv6 addresses (from the earlier merge of CIFS).

CRED: Wrap task credential accesses in the netrom protocol

2008-11-13T23:39:08+00:00

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.

Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

Change some task->e?[ug]id to task_e?[ug]id().  In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.

net: '&' redux

2008-11-04T02:21:05+00:00

I want to compile out proc_* and sysctl_* handlers totally and
stub them to NULL depending on config options, however usage of &
will prevent this, since taking adress of NULL pointer will break
compilation.

So, drop & in front of every ->proc_handler and every ->strategy
handler, it was never needed in fact.

netrom: Fix sock_orphan() use in nr_release

2008-10-06T19:54:57+00:00

While debugging another bug it was found that NetRom socks
are sometimes seen unorphaned in sk_free(). This patch moves
sock_orphan() in nr_release() to the beginning (like in ax25,
or rose).

netdev: Handle ->addr_list_lock just like ->_xmit_lock for lockdep.

2008-07-22T21:16:42+00:00

The new address list lock needs to handle the same device layering
issues that the _xmit_lock one does.

This integrates work done by Patrick McHardy.

netns: Use net_eq() to compare net-namespaces for optimization.

2008-07-20T05:34:43+00:00

Without CONFIG_NET_NS, namespace is always &init_net.
Compiler will be able to omit namespace comparisons with this patch.

netdev: Allocate multiple queues for TX.

2008-07-18T02:21:00+00:00

alloc_netdev_mq() now allocates an array of netdev_queue
structures for TX, based upon the queue_count argument.

Furthermore, all accesses to the TX queues are now vectored
through the netdev_get_tx_queue() and netdev_for_each_tx_queue()
interfaces.  This makes it easy to grep the tree for all
things that want to get to a TX queue of a net device.

Problem spots which are not really multiqueue aware yet, and
only work with one queue, can easily be spotted by grepping
for all netdev_get_tx_queue() calls that pass in a zero index.

netdev: Move _xmit_lock and xmit_lock_owner into netdev_queue.

2008-07-09T06:13:53+00:00

Accesses are mostly structured such that when there are multiple TX
queues the code transformations will be a little bit simpler.
