* netns bridge: allow bridges in netns!Alexey Dobriyan2008-09-081-3/+0
| | | | | | | | | | | | | | Bridge as netdevice doesn't cross netns boundaries. Bridge ports and bridge itself live in same netns. Notifiers are fixed. netns propagated from userspace socket for setup and teardown.

* netns: Use net_eq() to compare net-namespaces for optimization.YOSHIFUJI Hideaki2008-07-191-1/+1
| | | | | | | | Without CONFIG_NET_NS, namespace is always &init_net. Compiler will be able to omit namespace comparisons with this patch. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* bridge: Use STP demuxPatrick McHardy2008-07-051-9/+3
| | | | | | | | 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>

* [NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.YOSHIFUJI Hideaki2008-03-261-1/+1
| | | | | | | | Introduce per-net_device inlines: dev_net(), dev_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
* [NET]: Make packet reception network namespace safeEric W. Biederman2007-10-101-0/+4
| | | | | | | | | | | | | | This patch modifies every packet receive function registered with dev_add_pack() to drop packets if they are not from the initial network namespace. This should ensure that the various network stacks do not receive packets in a anything but the initial network namespace until the code has been converted and is ready for them.

* [NET]: DIV_ROUND_UP cleanup (part two)Ilpo Järvinen2007-10-101-1/+1
| | | | | | | | | | | Hopefully captured all single statement cases under net/. I'm not too sure if there is some policy about #includes that are "guaranteed" (ie., in the current tree) to be available through some other #included header, so I just added linux/kernel.h to each changed file that didn't #include it previously.

* bridge: add support for user mode STPStephen Hemminger2007-04-251-6/+13
| | | | | | | | | | This patchset based on work by Aji_Srinivas@emc.com provides allows spanning tree to be controled from userspace. Like hotplug, it uses call_usermodehelper when spanning tree is enabled so there is no visible API change. If call to start usermode STP fails it falls back to existing kernel STP.

* [BRIDGE]: random extra bytes on STP TCN packetStephen Hemminger2006-09-171-1/+1
| | | | | | | | We seem to send 3 extra bytes in a TCN, which will be whatever happens to be on the stack. Thanks to Aji_Srinivas@emc.com for seeing. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BRIDGE]: Unaligned accesses in the ethernet bridgePeter Chubb2006-03-241-2/+3
| | | | | | | | | | | | | | I see lots of kernel unaligned access to 0xa0000001009dbb6f, ip=0xa000000100811591 kernel unaligned access to 0xa0000001009dbb6b, ip=0xa0000001008115c1 kernel unaligned access to 0xa0000001009dbb6d, ip=0xa0000001008115f1 messages in my logs on IA64 when using the ethernet bridge with 2.6.16. Appended is a patch to fix them. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BRIDGE]: use LLC to send STPStephen Hemminger2006-03-201-69/+59
| | | | | | | | The bridge code can use existing LLC output code when building spanning tree protocol packets. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BRIDGE]: allow show/store of group multicast addressStephen Hemminger2006-03-201-2/+2
| | | | | | | | | | | | | | Bridge's communicate with each other using Spanning Tree Protocol over a standard multicast address. There are times when testing or layering bridges over existing topologies or tunnels, when it is useful to use alternative multicast addresses for STP packets. The 802.1d standard has some unused addresses, that can be used for this. This patch is restrictive in that it only allows one of the possible addresses in the standard.

* [BRIDGE]: use llc for receiving STP packetsStephen Hemminger2006-03-201-18/+33
| | | | | | | | | | | | | | | 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.

* [BRIDGE]: stp timer to jiffies cleanupStephen Hemminger2006-03-201-9/+8
| | | | | | | | Cleanup the get/set of bridge timer value in the packets. It is clearer not to bury the conversion in macro. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [BRIDGE]: fix for RCU and deadlock on device removalStephen Hemminger2006-02-091-12/+18
| | | | | | | | | Change Bridge receive path to correctly handle RCU removal of device from bridge. Also fixes deadlock between carrier_check and del_nbp. This replaces the previous deleted flag fix.

* [BRIDGE]: prevent bad forwarding table updatesStephen Hemminger2005-05-291-0/+3
| | | | | | | | | | Avoid poisoning of the bridge forwarding table by frames that have been dropped by filtering. This prevents spoofed source addresses on hostile side of bridge from causing packet leakage, a small but possible security risk.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+205
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!
