bridge: Forward reserved group addresses if !STP

2010-10-21T11:25:48+00:00

Make all frames sent to reserved group MAC addresses (01:80:c2:00:00:00 to
01:80:c2:00:00:0f) be forwarded if STP is disabled. This enables
forwarding EAPOL frames, among other things.

bridge: Add support for TX vlan offload.

2010-10-21T08:26:54+00:00

If some of the underlying devices support it, enable vlan offload on
transmit for bridge devices.  This allows senders to take advantage of the
hardware support, similar to other forms of acceleration.

vlan: Rename VLAN_GROUP_ARRAY_LEN to VLAN_N_VID.

2010-10-21T08:26:50+00:00

VLAN_GROUP_ARRAY_LEN is simply the number of possible vlan VIDs.
Since vlan groups will soon be more of an implementation detail
for vlan devices, rename the constant to be descriptive of its
actual purpose.

ebtables: Allow filtering of hardware accelerated vlan frames.

2010-10-21T08:26:49+00:00

An upcoming commit will allow packets with hardware vlan acceleration
information to be passed though more parts of the network stack, including
packets trunked through the bridge.  This adds support for matching and
filtering those packets through ebtables.

net dst: use a percpu_counter to track entries

2010-10-11T20:06:53+00:00

struct dst_ops tracks number of allocated dst in an atomic_t field,
subject to high cache line contention in stress workload.

Switch to a percpu_counter, to reduce number of time we need to dirty a
central location. Place it on a separate cache line to avoid dirtying
read only fields.

Stress test :

(Sending 160.000.000 UDP frames,
IP route cache disabled, dual E5540 @2.53GHz,
32bit kernel, FIB_TRIE, SLUB/NUMA)

Before:

real    0m51.179s
user    0m15.329s
sys     10m15.942s

After:

real	0m45.570s
user	0m15.525s
sys	9m56.669s

With a small reordering of struct neighbour fields, subject of a
following patch, (to separate refcnt from other read mostly fields)

real	0m41.841s
user	0m15.261s
sys	8m45.949s

bridge : Sanitize skb before it enters the IP stack

2010-09-19T19:42:34+00:00

Related dicussion here : http://lkml.org/lkml/2010/9/3/16

Introduce a function br_parse_ip_options that will audit the
skb and possibly refill IP options before a packet enters the
IP stack. If no options are present, the function will zero out
the skb cb area so that it is not misinterpreted as options by some
unsuspecting IP layer routine. If packet consistency fails, drop it.

bridge: Clear INET control block of SKBs passed into ip_fragment().

2010-09-02T02:17:34+00:00

In a similar vain to commit 17762060c25590bfddd68cc1131f28ec720f405f
("bridge: Clear IPCB before possible entry into IP stack")

Any time we call into the IP stack we have to make sure the state
there is as expected by the ipv4 code.

With help from Eric Dumazet and Herbert Xu.
