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.

[NET]: Simple ctl_table to ctl_path conversions.

2008-01-28T23:01:07+00:00

This patch includes many places, that only required
replacing the ctl_table-s with appropriate ctl_paths
and call register_sysctl_paths().

Nothing special was done with them.
