Håkon Bugge c764f2d899 RDMA/cma: Protect RMW with qp_mutex 
[ Upstream commit ca0c448d2b9f43e3175835d536853854ef544e22 ]

The struct rdma_id_private contains three bit-fields, tos_set,
timeout_set, and min_rnr_timer_set. These are set by accessor functions
without any synchronization. If two or all accessor functions are invoked
in close proximity in time, there will be Read-Modify-Write from several
contexts to the same variable, and the result will be intermittent.

Fixed by protecting the bit-fields by the qp_mutex in the accessor
functions.

The consumer of timeout_set and min_rnr_timer_set is in
rdma_init_qp_attr(), which is called with qp_mutex held for connected
QPs. Explicit locking is added for the consumers of tos and tos_set.

This commit depends on ("RDMA/cma: Remove unnecessary INIT->INIT
transition"), since the call to rdma_init_qp_attr() from
cma_init_conn_qp() does not hold the qp_mutex.

Fixes: 2c1619edef ("IB/cma: Define option to set ack timeout and pack tos_set")
Fixes: 3aeffc46afde ("IB/cma: Introduce rdma_set_min_rnr_timer()")
