2013-08-20vxlan: using kfree_rcu() to simplify the codeWei Yongjun1-7/+1

2013-08-09vxlan: fix a soft lockup in vxlan module removalCong Wang1-2/+0
This is a regression introduced by: commit fe5c3561e6f0ac7c9546209f01351113c1b77ec8 Author: stephen hemminger <stephen@networkplumber.org> Date: Sat Jul 13 10:18:18 2013 -0700 vxlan: add necessary locking on device removal The problem is that vxlan_dellink(), which is called with RTNL lock held, tries to flush the workqueue synchronously, but apparently igmp_join and igmp_leave work need to hold RTNL lock too, therefore we have a soft lockup! As suggested by Stephen, probably the flush_workqueue can just be removed and let the normal refcounting work. The workqueue has a reference to device and socket, therefore the cleanups should work correctly.

2013-07-23vxlan fdb replace an existing entryThomas Richter1-0/+38
Add support to replace an existing entry found in the vxlan fdb database. The entry in question is identified by its unicast mac address and the destination information is changed. If the entry is not found, it is added in the forwarding database. This is similar to changing an entry in the neighbour table. Multicast mac addresses can not be changed with the replace option. This is useful for virtual machine migration when the destination of a target virtual machine changes. The replace feature can be used instead of delete followed by add.

2013-07-19vxlan: fix igmp racesstephen hemminger1-15/+38
There are two race conditions in existing code for doing IGMP management in workqueue in vxlan. First, the vxlan_group_used function checks the list of vxlan's without any protection, and it is possible for open followed by close to occur before the igmp work queue runs. To solve these move the check into vxlan_open/stop so it is protected by RTNL. And split into two work structures so that there is no racy reference to underlying device state.

The socket management is now done in workqueue (outside of RTNL) and protected by vn->sock_lock.

2013-07-11vxlan: Fix kernel crash on rmmod.Pravin B Shelar1-1/+1
vxlan exit module unregisters vxlan net and then it unregisters rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links(). vxlan_dellink() deletes vxlan-dev from vxlan_list which has list-head in vxlan-net-struct but that is already gone due to net-unregister. That is how we are getting following crash. Following commit fixes the crash by fixing module exit path.

2013-06-24vxlan: fix race caused by dropping rtnl_unlockStephen Hemminger1-27/+84
It is possible for two cpu's to race creating vxlan device. For most cases this is harmless, but the ability to assign "next avaliable vxlan device" relies on rtnl lock being held across the whole operation. Therfore two instances of calling: ip li add vxlan%d vxlan ... could collide and create two devices with same name. To fix this defer creation of socket to a work queue, and handle possible races there. Introduce a lock to ensure that changes to vxlan socket hash list is SMP safe.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>
