| | | | | | | | | | | | | | | | | | | | | | | | | | | ib_create_ah_from_wc() doesn't create the correct return address (AH) when there is a GRH present (source & dest GIDs need to be swapped).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ib_uverbs_create_cq() should release the completion channel event file if an error occurs after it looks it up. Also, if userspace asks for a completion channel and we don't find it, an error should be returned instead of silently creating a CQ without a completion channel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multicast group management fixes: . Fix leak of mailbox memory in error handling on multicast group operations. . Free AMGM indices at detach and in attach error handling. . Fix amount to shift for aligning next_gid_index in mailbox: it starts at bit 6, not bit 5. . Allocate AMGM index after end of MGM table, in the range num_mgms to multicast table size - 1. Add some BUG_ON checks to catch cases where the index falls in the MGM hash area. . Initialize the list of QPs in a newly-allocated group from AMGM to 0 This is necessary since when a group is moved from AMGM to MGM (in the case where the MGM entry has been emptied of QPs), the AMGM entry is not reset to 0 (and we don't want an extra command to do that).

| | * IB/mthca: Fix IB_QP_ACCESS_FLAGS handling.Jack Morgenstein2005-12-151-50/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects some corner cases in managing the RAE/RRE bits in the mthca qp context. These bits need to be zero if the user requests max_dest_rd_atomic of zero. The bits need to be restored to the value implied by the qp access flags attribute in a previous (or the current) modify-qp command if the dest_rd_atomic variable is changed to non-zero. In the current implementation, the following scenario will not work: RESET-to-INIT set QP access flags to all disabled (zeroes) INIT-to-RTR set max_dest_rd_atomic=10, AND set qp_access_flags = IB_ACCESS_REMOTE_READ | IB_ACCESS_REMOTE_ATOMIC The current code will incorrectly take the access-flags value set in the RESET-to-INIT transition. We can simplify, and correct, this IB_QP_ACCESS_FLAGS handling: it is always safe to set qp access flags in the firmware command if either of IB_QP_MAX_DEST_RD_ATOMIC or IB_QP_ACCESS_FLAGS is set, so let's just set it to the correct value, always.

| * | [PATCH] fix workqueue oops during cpu offlineNathan Lynch2006-01-081-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use first_cpu(cpu_possible_map) for the single-thread workqueue case. We used to hardcode 0, but that broke on systems where !cpu_possible(0) when workqueue_struct->cpu_workqueue_struct was changed from a static array to alloc_percpu. Commit id bce61dd49d6ba7799be2de17c772e4c701558f14 ("Fix hardcoded cpu=0 in workqueue for per_cpu_ptr() calls") fixed that for Ben's funky sparc64 system, but it regressed my Power5. Offlining cpu 0 oopses upon the next call to queue_work for a single-thread workqueue, because now we try to manipulate per_cpu_ptr(wq->cpu_wq, 1), which is uninitialized. So we need to establish an unchanging "slot" for single-thread workqueues which will have a valid percpu allocation. Since alloc_percpu keys off of cpu_possible_map, which must not change after initialization, make this slot == first_cpu(cpu_possible_map).
