linux-toradex.git/drivers/infiniband/core, branch v3.6.1 Linux kernel for Apalis and Colibri modules RDMA/ucma.c: Fix for events with wrong context on iWARP 2012-08-13T20:08:35+00:00 Tatyana Nikolova Tatyana.E.Nikolova@intel.com 2012-08-03T23:59:41+00:00 418edaaba96e58112b15c82b4907084e2a9caf42 It is possible for asynchronous RDMA_CM_EVENT_ESTABLISHED events to be generated with ctx->uid == 0, because ucma_set_event_context() copies ctx->uid to the event structure outside of ctx->file->mut. This leads to a crash in the userspace library, since it gets a bogus event. Fix this by taking the mutex a bit earlier in ucma_event_handler.

Provide an option for the user to specify that listens should only
accept connections where the incoming address family matches that of
the locally bound address.  This is used to support the equivalent of
IPV6_V6ONLY socket option, which allows an app to only accept
connection requests directed to IPv6 addresses.
