bridge: set priority of STP packets

2013-02-11T19:16:52Z

Spanning Tree Protocol packets should have always been marked as control packets, this causes them to get queued in the high prirority FIFO. As Radia Perlman mentioned in her LCA talk, STP dies if bridge gets overloaded and can't communicate. This is a long-standing bug back to the first versions of Linux bridge.

bridge: add empty br_mdb_init() and br_mdb_uninit() definitions.

2013-01-03T11:35:22Z

This patch adds empty br_mdb_init() and br_mdb_uninit() definitions in br_private.h to avoid build failure when CONFIG_BRIDGE_IGMP_SNOOPING is not set. These methods were moved from br_multicast.c to br_netlink.c by commit 3ec8e9f085bcaef0de1077f555c2c5102c223390 Signed-off-by: Rami Rosen Signed-off-by: David S. Miller

bridge: Correctly unregister MDB rtnetlink handlers

2013-01-03T09:56:11Z

Commit 63233159fd4e596568f5f168ecb0879b61631d47: bridge: Do not unregister all PF_BRIDGE rtnl operations introduced a bug where a removal of a single bridge from a multi-bridge system would remove MDB netlink handlers. The handlers should only be removed once all bridges are gone, but since we don't keep track of the number of bridge interfaces, it's simpler to do it when the bridge module is unloaded. To make it consistent, move the registration code into module initialization code path. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

bridge: call br_netpoll_disable in br_add_if

2012-12-21T21:17:07Z

When netdev_set_master faild in br_add_if, we should call br_netpoll_disable to do some cleanup jobs,such as free the memory of struct netpoll which allocated in br_netpoll_enable. Signed-off-by: Gao feng Acked-by: Cong Wang Signed-off-by: David S. Miller

bridge: Correctly encode addresses when dumping mdb entries

2012-12-19T20:50:06Z

When dumping mdb table, set the addresses the kernel returns based on the address protocol type. Signed-off-by: Vlad Yasevich Acked-by: Cong Wang Signed-off-by: David S. Miller

bridge: Do not unregister all PF_BRIDGE rtnl operations

2012-12-19T20:50:06Z

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.

bridge: add flags to distinguish permanent mdb entires

2012-12-16T01:14:39Z

This patch adds a flag to each mdb entry, so that we can distinguish permanent entries with temporary entries. Cc: Herbert Xu Cc: Stephen Hemminger Cc: "David S. Miller" Signed-off-by: Cong Wang Signed-off-by: David S. Miller

bridge: remove temporary variable for MLDv2 maximum response code computation

2012-12-14T18:14:06Z

As suggested by Stephen Hemminger, this remove the temporary variable introduced in commit eca2a43bb0d2c6ebd528be6acb30a88435abe307 ("bridge: fix icmpv6 endian bug and other sparse warnings") Signed-off-by: Ang Way Chuang Acked-by: Stephen Hemminger Signed-off-by: David S. Miller

bridge: fix icmpv6 endian bug and other sparse warnings

2012-12-13T17:58:11Z

Fix the warnings reported by sparse on recent bridge multicast changes. Mostly just rcu annotation issues but in this case sparse found a real bug! The ICMPv6 mld2 query mrc values is in network byte order. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

bridge: add support of adding and deleting mdb entries

2012-12-12T18:02:30Z

This patch implents adding/deleting mdb entries via netlink. Currently all entries are temp, we probably need a flag to distinguish permanent entries too. Cc: Herbert Xu Cc: Stephen Hemminger Cc: "David S. Miller" Cc: Thomas Graf Signed-off-by: Cong Wang Signed-off-by: David S. Miller
