net/netrom: Fix socket locking

2009-05-02T17:24:05+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.

af_rose/x25: Sanity check the maximum user frame size

2009-05-02T17:24:04+00:00

upstream commit: 83e0bbcbe2145f160fbaa109b0439dae7f4a38a9

CVE-2009-0795.

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

Closes #10423

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.

netrom: Kill spurious NULL'ing of sk->sk_socket.

2008-06-17T10:19:58+00:00

In nr_release(), one code path calls sock_orphan() which
will NULL out sk->sk_socket already.

In the other case, handling states other than NR_STATE_{0,1,2,3},
seems to not be possible other than due to bugs.  Even for an
uninitialized nr->state value, that would be zero or NR_STATE_0.
It might be wise to stick a WARN_ON() here.

netrom: Use sock_graft() and remove bogus sk_socket and sk_sleep init.

[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.

2008-03-25T19:39:55+00:00

Introduce per-sock inlines: sock_net(), sock_net_set()
and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.
