Subject: [Patch 0/3] Hangs with IPoIB when doing PCI error injection
Date: Thu, 27 Mar 2014 09:28:13 -0500 [thread overview]
Message-ID: <20140327142813.535289178@linux.vnet.ibm.com> (raw)
This patch is to resolve some hangs we are seeing when doing PCI error injection
to Mellanox Infiniband cards. With this patch we make mlx4 driver send an IB_EVENT_DEVICE_FATAL
to the users and added this event to event handlers to avoid these hangs.
If IPoIB is in connected mode, then added to cm an event handler and tried to
make sure that when it sees the fatal event it does not try to send anymore packet because
it will not receive any more completions or interrupts.
