2013-03-10	bridge: fix mdb info leaks	Mathias Krause
	The bridging code discloses heap and stack bytes via the RTM_GETMDB netlink interface and via the notify messages send to group RTNLGRP_MDB afer a successful add/del. Fix both cases by initializing all unset members/padding bytes with memset(0).

2013-02-28	hlist: drop the node parameter from iterators	Sasha Levin
	I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S \| hlist_for_each_entry_continue(a, - b, c) S \| hlist_for_each_entry_from(a, - b, c) S \| hlist_for_each_entry_rcu(a, - b, c, d) S \| hlist_for_each_entry_rcu_bh(a, - b, c, d) S \| hlist_for_each_entry_continue_rcu_bh(a, - b, c) S \| for_each_busy_worker(a, c, - b, d) S \| ax25_uid_for_each(a, - b, c) S \| ax25_for_each(a, - b, c) S \| inet_bind_bucket_for_each(a, - b, c) S \| sctp_for_each_hentry(a, - b, c) S \| sk_for_each(a, - b, c) S \| sk_for_each_rcu(a, - b, c) S \| sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S \| sk_for_each_safe(a, - b, c, d) S \| sk_for_each_bound(a, - b, c) S \| hlist_for_each_entry_safe(a, - b, c, d, e) S \| hlist_for_each_entry_continue_rcu(a, - b, c) S \| nr_neigh_for_each(a, - b, c) S \| nr_neigh_for_each_safe(a, - b, c, d) S \| nr_node_for_each(a, - b, c) S \| nr_node_for_each_safe(a, - b, c, d) S \| - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S \| - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S \| for_each_host(a, - b, c) S \| for_each_host_safe(a, - b, c, d) S \| for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

2013-02-04	netns: bridge: allow unprivileged users add/delete mdb entry	Gao feng
	since the mdb table is belong to bridge device,and the bridge device can only be seen in one netns. So it's safe to allow unprivileged user which is the creator of userns and netns to modify the mdb table. Signed-off-by: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by: David S.

2012-12-19	bridge: Do not unregister all PF_BRIDGE rtnl operations	Vlad Yasevich
	Bridge fdb and link rtnl operations are registered in core/rtnetlink. Bridge mdb operations are registred in bridge/mdb. When removing bridge module, do not unregister ALL PF_BRIDGE ops since that would remove the ops from rtnetlink as well. Do remove mdb ops when bridge is destroyed.

2012-12-16	bridge: add flags to distinguish permanent mdb entires	Amerigo Wang

2012-12-12	bridge: add support of adding and deleting mdb entries	Cong 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.

2012-12-11	bridge: 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.

2012-12-07	bridge: export multicast database via netlink	Cong 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).
