RDS on IB uses privdata to do protocol version negotiation. Apparently the IB stack will return a larger privdata buffer than the struct we were expecting. Just to be extra-sure, this patch adds some checks in this area. Signed-off-by: NAndy Grover <andy.grover@oracle.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This will be default cause IB connections to failover faster, but allow a longer retry count to be used if desired. Signed-off-by: NAndy Grover <andy.grover@oracle.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We have a 64bit value that needs to be set atomically. This is easy and quick on all 64bit archs, and can also be done on x86/32 with set_64bit() (uses cmpxchg8b). However other 32b archs don't have this. I actually changed this to the current state in preparation for mainline because the old way (using a spinlock on 32b) resulted in unsightly #ifdefs in the code. But obviously, being correct takes precedence. Signed-off-by: NAndy Grover <andy.grover@oracle.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This fixes a bug where a connection was unexpectedly not on *any* list while being destroyed. It also cleans up some code duplication and regularizes some function names. * Grab appropriate lock in conn_free() and explain in comment * Ensure via locking that a conn is never not on either a dev's list or the nodev list * Add rds_xx_remove_conn() to match rds_xx_add_conn() * Make rds_xx_add_conn() return void * Rename remove_{,nodev_}conns() to destroy_{,nodev_}conns() and unify their implementation in a helper function * Document lock ordering as nodev conn_lock before dev_conn_lock Reported-by: NYosef Etigin <yosefe@voltaire.com> Signed-off-by: NAndy Grover <andy.grover@oracle.com> Signed-off-by: NDavid S.

Registers as an RDS transport and an IB client, and uses IB CM API to allocate ids, queue pairs, and the rest of that fun stuff. Signed-off-by: NAndy Grover <andy.grover@oracle.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
