Revision 8fe8bacb92f249c91a1407b48aa1cb98067fe19d authored by Majd Dibbiny on 30 May 2017, 06:58:06 UTC, committed by Doug Ledford on 18 July 2017, 01:21:25 UTC
Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs according to the netdev events. The ib_wq isn't an ordered workqueue and thus two work elements can be executed concurrently which will result in unexpected behavior and inconsistency of the GIDs cache content. Example: ifconfig eth1 11.11.11.11/16 up This command will invoke the following netdev events in the following order: 1. NETDEV_UP 2. NETDEV_DOWN 3. NETDEV_UP If (2) and (3) will be executed concurrently or in reverse order, instead of having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.
