| * [PATCH] IB: fix CM use-after-freeRoland Dreier2005-09-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | If the CM REQ handling function gets to error2, then it frees cm_id_priv->timewait_info. But the next line goes through ib_destroy_cm_id() -> ib_send_cm_rej() -> cm_reset_to_idle(), which ends up calling cm_cleanup_timewait(), which dereferences the pointer we just freed. Make sure we clear cm_id_priv->timewait_info after freeing it, so that doesn't happen. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * Make sure that userspace does not retrieve stale asynchronous orRoland Dreier2005-09-093-88/+191
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | completion events after destroying a CQ, QP or SRQ. We do this by sweeping the event lists before returning from a destroy calls, and then return the number of events already reported before the destroy call. This allows userspace wait until it has processed all events for an object returned from the kernel before it frees its context for the object. The ABI of the destroy CQ, destroy QP and destroy SRQ commands has to change to return the event count, so bump the ABI version from 1 to 2. The userspace libibverbs library has already been updated to handle both the old and new ABI versions. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * [PATCH] IB: RMPP fixesHal Rosenstock2005-09-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Fix payload length of middle RMPP sent segments. Middle payload lengths should be 0 on the send side. (This is perhaps a compliance and should not be an interop issue as middle payload lengths are supposed to be ignored on receive). - Fix length in first segment of multipacket sends (This is a compliance issue but does not affect at least OpenIB to OpenIB RMPP transfers).

Users will not retrieve any events associated with the context after destroying the corresponding cm_id. - Provide the ib_cm_init_qp_attr() call to userspace clients of the CM. This call may be used to set QP attributes properly before modifying the QP. - Fixes some error handling synchonization and cleanup issues. - Performs some minor code cleanup.

* [PATCH] IB: userspace SRQ supportRoland Dreier2005-08-263-3/+204
| | | | | | | | | | | | | | | | | | | | Add SRQ support to userspace verbs module. This adds several commands and associated structures, but it's OK to do this without bumping the ABI version because the commands are added at the end of the list so they don't change the existing numbering. There are two cases to worry about: 1. New kernel, old userspace. This is OK because old userspace simply won't try to use the new SRQ commands. None of the old commands are changed. 2. Old kernel, new userspace. This works perfectly as long as userspace doesn't try to use SRQ commands. If userspace tries to use SRQ commands, it will get EINVAL, which is perfectly reasonable: the kernel doesn't support SRQs, so we couldn't do any better.
