* bridge: change console message interfacestephen hemminger2010-05-151-1/+1
| | | | | | | | | | Use one set of macro's for all bridge messages. Note: can't use netdev_XXX macro's because bridge is purely virtual and has no device parent. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bridge: Use rcu_barrier() instead of syncronize_net() on unload.Jesper Dangaard Brouer2009-06-261-1/+1
| | | | | | | | | | When unloading modules that uses call_rcu() callbacks, then we must use rcu_barrier(). This module uses syncronize_net() which is not enough to be sure that all callback has been completed. Acked-by: Paul E.

* bridge: Simplify interface for ATM LANEMichał Mirosław2009-06-111-4/+6
| | | | | | | | | | | | | | | This patch changes FDB entry check for ATM LANE bridge integration. There's no point in holding a FDB entry around SKB building. br_fdb_get()/br_fdb_put() pair are changed into single br_fdb_test_addr() hook that checks if the addr has FDB entry pointing to other port to the one the request arrived on. FDB entry refcounting is removed as it's not used anywhere else. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

* bridge: kernel panic when unloading bridge moduleBodo Stroesser2008-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | There is a race condition when unloading bridge and netfilter. The problem happens if __fake_rtable is in use by a skb coming in, while someone starts to unload bridge.ko. br_netfilter_fini() is called at the beginning of unload in br_deinit() while skbs still are being forwarded and transferred to local ip stack. Thus there is a possibility of the __fake_rtable pointer not being removed in a skb that goes up to ip stack. This results in a kernel panic, as ip_rcv() calls the input-function of __fake_rtable, which is NULL. Moving the call of br_netfilter_fini() to the end of br_deinit() solves the problem.

* [BRIDGE]: Lost call to br_fdb_fini() in br_init() error pathPavel Emelyanov2007-11-291-1/+3
| | | | | | | | | In case the br_netfilter_init() (or any subsequent call) fails, the br_fdb_fini() must be called to free the allocated in br_fdb_init() br_fdb_cache kmem cache. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [BRIDGE]: netlink interface for link managementStephen Hemminger2006-06-171-0/+2
| | | | | | | | | | | | | | | | Add basic netlink support to the Ethernet bridge. Including: * dump interfaces in bridges * monitor link status changes * change state of bridge port For some demo programs see: http://developer.osdl.org/shemminger/prototypes/brnl.tar.gz These are to allow building a daemon that does alternative implementations of Spanning Tree Protocol.

* [BRIDGE]: need to ref count the LLC sapStephen Hemminger2006-05-231-1/+2
| | | | | | | | | | | | Bridge will OOPS on removal if other application has the SAP open. The bridge SAP might be shared with other usages, so need to do reference counting on module removal rather than explicit close/delete. Since packet might arrive after or during removal, need to clear the receive function handle, so LLC only hands it to user (if any).

* [BRIDGE]: use llc for receiving STP packetsStephen Hemminger2006-03-201-0/+12
| | | | | | | | | | | | | | | Use LLC for the receive path of Spanning Tree Protocol packets. This allows link local multicast packets to be received by other protocols (if they care), and uses the existing LLC code to get STP packets back into bridge code. The bridge multicast address is also checked, so bridges using other link local multicast addresses are ignored. This allows for use of different multicast addresses to define separate STP domains.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+69
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
