From: Thomas Graf <tgraf@xxxxxxxxxxxxx> Date: Tue, 21 Jun 2011 09:11:20 -0400 > This patch adds a change sequence counter to each net namespace > which is bumped whenever a netdevice is added or removed from > the list. If such a change occurred while a link dump took place, > the dump will have the NLM_F_DUMP_INTR flag set in the first > message which has been interrupted and in all subsequent messages > of the same dump. > > Note that links may still be modified or renamed while a dump is > taking place but we can guarantee for userspace to receive a > complete list of links and not miss any. > > Testing: > I have added 500 VLAN netdevices to make sure the dump is split > over multiple messages. Then while continuously dumping links in > one process I also continuously deleted and re-added a dummy > netdevice in another process. Multiple dumps per seconds have > had the NLM_F_DUMP_INTR flag set. > > I guess we can wait for Johannes patch to hit net-next via the > wireless tree. I just wanted to give this some testing right away. > > Signed-off-by: Thomas Graf <tgraf@xxxxxxxxxxxxx> Applied. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
