ipv6 mcast: use in6_dev_put in timer handlers instead of __in6_dev_put

2014-05-19T05:53:38Z

[ Upstream commit 9260d3e1013701aa814d10c8fc6a9f92bd17d643 ] It is possible for the timer handlers to run after the call to ipv6_mc_down so use in6_dev_put instead of __in6_dev_put in the handler function in order to do proper cleanup when the refcnt reaches 0. Otherwise, the refcnt can reach zero without the inet6_dev being destroyed and we end up leaking a reference to the net_device and see messages like the following, unregister_netdevice: waiting for eth0 to become free. Usage count = 1 Tested on linux-3.4.43. Signed-off-by: Salam Noureddine Signed-off-by: David S. Miller Signed-off-by: Willy Tarreau

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.

mcastv6: Local variable shadows function argument

2009-07-21T18:13:25Z

The local variable 'idev' shadows the function argument 'idev' to ip6_mc_add_src(). Fixed by removing the local declaration, as pmc->idev should be identical with 'idev' passed as argument. Signed-off-by: Gerrit Renker Acked-by: David L Stevens Signed-off-by: David S. Miller

snmp: add missing counters for RFC 4293

2009-04-27T09:45:02Z

The IP MIB (RFC 4293) defines stats for InOctets, OutOctets, InMcastOctets and OutMcastOctets: http://tools.ietf.org/html/rfc4293 But it seems we don't track those in any way that easy to separate from other protocols. This patch adds those missing counters to the stats file. Tested successfully by me With help from Eric Dumazet. Signed-off-by: Neil Horman Signed-off-by: David S. Miller
