2012-12-15bridge: add flags to distinguish permanent mdb entiresAmerigo Wang
This patch adds a flag to each mdb entry, so that we can distinguish permanent entries with temporary entries.

2012-12-12bridge: add support of adding and deleting mdb entriesCong Wang
This patch implents adding/deleting mdb entries via netlink. Currently all entries are temp, we probably need a flag to distinguish permanent entries too.

2012-12-12bridge: notify mdb changes via netlinkCong Wang
As Stephen mentioned, we need to monitor the mdb changes in user-space, so add notifications via netlink too.

2012-12-11bridge: fix seq check in br_mdb_dump()Cong Wang
In case of rehashing, introduce a global variable 'br_mdb_rehash_seq' which gets increased every time when rehashing, and assign net->dev_base_seq + br_mdb_rehash_seq to cb->seq. In theory cb->seq could be wrapped to zero, but this is not easy to fix, as net->dev_base_seq is not visible inside br_mdb_rehash(). In practice, this is rare.

2012-12-07bridge: export multicast database via netlinkCong Wang
V5: fix two bugs pointed out by Thomas remove seq check for now, mark it as TODO V4: remove some useless #include some coding style fix V3: drop debugging printk's update selinux perm table as well V2: drop patch 1/2, export ifindex directly Redesign netlink attributes Improve netlink seq check Handle IPv6 addr as well This patch exports bridge multicast database via netlink message type RTM_GETMDB. Similar to fdb, but currently bridge-specific. We may need to support modify multicast database too (RTM_{ADD,DEL}MDB). (Thanks to Thomas for patient reviews) Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Stephen Hemminger <shemminger@vyatta.com> Cc: "David S.
