net: bug fix for vlan + gro issue

2010-03-15T15:49:39Z

[ Upstream commit e76b69cc0133952c98aa1ad6330cacacd269fd64 ] Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

net: Fix userspace RTM_NEWLINK notifications.

2009-12-18T22:05:38Z

commit d90a909e1f3e006a1d57fe11fd417173b6494701 upstream. I received some bug reports about userspace programs having problems because after RTM_NEWLINK was received they could not immeidate access files under /proc/sys/net/ because they had not been registered yet. The problem was trivailly fixed by moving the userspace notification from rtnetlink_event to the end of register_netdevice. Signed-off-by: Eric W.

net: Fix the rollback test in dev_change_name()

2009-11-16T11:30:35Z

net: Fix the rollback test in dev_change_name() In dev_change_name() an err variable is used for storing the original call_netdevice_notifiers() errno (negative) and testing for a rollback error later, but the test for non-zero is wrong, because the err might have positive value as well - from dev_alloc_name(). It means the rollback for a netdevice with a number > 0 will never happen. (The err test is reordered btw. to make it more readable.)

net: restore tx timestamping for accelerated vlans

2009-09-30T23:42:42Z

Since commit 9b22ea560957de1484e6b3e8538f7eef202e3596 ( net: fix packet socket delivery in rx irq handler ) We lost rx timestamping of packets received on accelerated vlans. Effect is that tcpdump on real dev can show strange timings, since it gets rx timestamps too late (ie at skb dequeueing time, not at skb queueing time) 14:47:26.986871 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 1 14:47:26.986786 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 1 14:47:27.986888 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 2 14:47:27.986781 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 2 14:47:28.986896 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 3 14:47:28.986780 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 3 Signed-off-by: Eric Dumazet Signed-off-by: David S.

bonding: remap muticast addresses without using dev_close() and dev_open()

2009-09-15T09:37:40Z

This patch fixes commit e36b9d16c6a6d0f59803b3ef04ff3c22c3844c10. The approach there is to call dev_close()/dev_open() whenever the device type is changed in order to remap the device IP multicast addresses to HW multicast addresses. This approach suffers from 2 drawbacks: *. It assumes tha the device is UP when calling dev_close(), or otherwise dev_close() has no affect. It is worth to mention that initscripts (Redhat) and sysconfig (Suse) doesn't act the same in this matter. *. dev_close() has other side affects, like deleting entries from the routing table, which might be unnecessary. The fix here is to directly remap the IP multicast addresses to HW multicast addresses for a bonding device that changes its type, and nothing else.

Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use.

The only valid usage for the bridge frame hooks are by a GPL components (such as the bridge module). The kernel should not leave a crack in the door for proprietary networking stacks to slip in. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller
