We set up the ring buffer\nduring reboot, but not the offset into it. On older kernels, this\nwould cause a storm of thousands of spurious interrupts after a\nkexec, which would most of the time get dropped silently.\n\nWith the new code, we time out on each interrupt, waiting for\nit to become valid. If more interrupts come in that we time\nout on, this goes on indefinitely, which eventually leads to\na hard crash.\n\nThe solution in this commit is to read the current offset from\nthe MSIC when reinitializing it.

Since the poll_list isn\u0027t surrounded by any other\nstructure, the returned data from that list_entry call in this situation is\ngarbage, and any number of crashes can result based on what exactly that garbage\nis.\n\nGiven that its not fasible for performance reasons to place exclusive locks\narround each cpus poll list to provide that mutal exclusion, I think the best\nsolution is modify the netpoll path in such a way that we continue to guarantee\nthat the poll_list for a cpu is in fact exclusive to that cpu. To do this I\u0027ve\nimplemented the patch below. It adds an additional bit to the state field in\nthe napi_struct. When executing napi-\u003epoll from the netpoll_path, this bit will\nbe set. When a driver calls netif_rx_complete, if that bit is set, it will not\nremove the napi_struct from the poll_list. That work will be saved for the next\niteration of net_rx_action.\n\nI\u0027ve tested this and it seems to work well. About the biggest drawback I can\nsee to it is the fact that it might result in an extra loop through\nnet_rx_action in the event that the device is actually contended for (i.e. the\nnetpoll path actually preforms all the needed work no the device, and the call\nto net_rx_action winds up doing nothing, except removing the napi_struct from\nthe poll_list. However I think this is probably a small price to pay, given\nthat the alternative is a crash.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: David S.
