bridge: use br_port_get_rtnl within rtnl lock

2013-09-16T02:03:33+00:00

current br_port_get_rcu is problematic in bridging path
(NULL deref). Change these calls in netlink path first.

bridge: Use the correct bit length for bitmap functions in the VLAN code

2013-08-21T06:35:57+00:00

The VLAN code needs to know the length of the per-port VLAN bitmap to
perform its most basic operations (retrieving VLAN informations, removing
VLANs, forwarding database manipulation, etc). Unfortunately, in the
current implementation we are using a macro that indicates the bitmap
size in longs in places where the size in bits is expected, which in
some cases can cause what appear to be random failures.
Use the correct macro.

bridge: Add a flag to control unicast packet flood.

2013-06-11T09:04:32+00:00

Add a flag to control flood of unicast traffic.  By default, flood is
on and the bridge will flood unicast traffic if it doesn't know
the destination.  When the flag is turned off, unicast traffic
without an FDB will not be forwarded to the specified port.

bridge: Add flag to control mac learning.

2013-06-11T09:04:32+00:00

Allow user to control whether mac learning is enabled on the port.
By default, mac learning is enabled.  Disabling mac learning will
cause new dynamic FDB entries to not be created for a particular port.

bridge: avoid br_ifinfo_notify when nothing changed

2013-03-24T21:16:30+00:00

When neither IFF_BRIDGE nor IFF_BRIDGE_PORT is set,
and afspec == NULL but  protinfo != NULL, we run into
"if (err == 0) br_ifinfo_notify(RTM_NEWLINK, p);" with
random value in ret.

Thanks to Sergei for pointing out the error in commit comments.

bridge: Add support for setting BR_ROOT_BLOCK flag.

2013-03-17T16:41:29+00:00

Most of the support was already there.  The only thing that was missing
was the call to set the flag.  Add this call.

bridge: reserve space for IFLA_BRPORT_FAST_LEAVE

2013-03-12T09:38:29+00:00

The bridge multicast fast leave feature was added sufficient space
was not reserved in the netlink message. This means the flag may be
lost in netlink events and results of queries.

Found by observation while looking up some netlink stuff for discussion with Vlad.
