2008-07-06bridge: Use STP demuxPatrick McHardy1-7/+9
Use the STP demux layer for receiving STP PDUs instead of directly registering with LLC. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-29bridge: kernel panic when unloading bridge moduleBodo Stroesser1-1/+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.

2007-11-29[BRIDGE]: Lost call to br_fdb_fini() in br_init() error pathPavel Emelyanov1-1/+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>
2007-10-15[NETFILTER]: Replace sk_buff ** with sk_buff *Herbert Xu1-1/+1
With all the users of the double pointers removed, this patch mops up by finally replacing all occurances of sk_buff ** in the netfilter API by sk_buff *. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-06-18[BRIDGE]: netlink interface for link managementStephen Hemminger1-0/+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.

2006-06-18[BRIDGE]: fix module startup error handlingStephen Hemminger1-9/+17
Return address in use, if some other kernel code has the SAP. Propogate out error codes from netfilter registration and unwind. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-05-24[BRIDGE]: need to ref count the LLC sapStephen Hemminger1-1/+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).

2006-03-21[BRIDGE]: use llc for receiving STP packetsStephen Hemminger1-0/+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.

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!
