bridge: allow updating existing fdb entries

2011-10-03T16:17:33+00:00

Need to allow application to update existing fdb entries that already
exist. This makes bridge netlink neighbor API have same flags and
semantics as ip neighbor table.

bridge: allow creating/deleting fdb entries via netlink

2011-04-05T00:22:28+00:00

Use RTM_NEWNEIGH and RTM_DELNEIGH to allow updating of entries
in bridge forwarding table. This allows manipulating static entries
which is not possible with existing tools.

Example (using bridge extensions to iproute2)
   # br fdb add 00:02:03:04:05:06 dev eth0

bridge: add netlink notification on forward entry changes

2011-04-05T00:22:27+00:00

This allows applications to query and monitor bridge forwarding
table in the same method used for neighbor table. The forward table
entries are returned in same structure format as used by the ioctl.
If more information is desired in future, the netlink method is
extensible.

Example (using bridge extensions to iproute2)
  # br monitor

bridge: split rcu and no-rcu cases of fdb lookup

2011-04-05T00:22:26+00:00

In some cases, look up of forward database entry is done with RCU;
and for others no RCU is needed because of locking. Split the two
cases into two differnt loops (and take off inline).

bridge: change arguments to fdb_create

2011-04-05T00:22:25+00:00

Later patch provides ability to create non-local static entry.
To make this easier move the updating of the flag values to
after the code that creates entry.

bridge: Don't put partly initialized fdb into hash

2011-02-04T21:02:36+00:00

The fdb_create() puts a new fdb into hash with only addr set. This is
not good, since there are callers, that search the hash w/o the lock
and access all the other its fields.

Applies to current netdev tree.
