* IPoIB: Retry failed send-only multicast group joinsEli Cohen2006-09-141-0/+1
| | | | | | | | | | When a send-only multicast group join fails, mcast->query must be set to NULL. Otherwise, IPoIB will never retry the join and the multicast group will never be reachable.

* IB/srp: Don't schedule reconnect from srpIshai Rabinovitz2006-09-141-14/+0
| | | | | | | | | | | | | | | | If there is a problem in the connection, the SCSI mid-layer will eventually call srp_reset_host(), which will call srp_reconnect(), so we do not need to schedule a call to srp_reconnect_work() from srp_completion(). Removing this prevents srp_reset_host() from failing if a reconnect scheduled from srp_completion() is already in progress, which in turn was causing crashes as both SCSI midlayer and srp_reconnect() were cancelling commands.

* IB/mthca: Use IRQ safe locks to protect allocation bitmapsRoland Dreier2006-08-311-4/+11
| | | | | | | | | | | It is supposed to be OK to call mthca_create_ah() and mthca_destroy_ah() from any context. However, for mem-full HCAs, these functions use the mthca_alloc() and mthca_free() bitmap helpers, and those helpers use non-IRQ-safe spin_lock() internally. Lockdep correctly warns that this could lead to a deadlock. Fix this by changing mthca_alloc() and mthca_free() to use spin_lock_irqsave(). Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * | [SCSI] iscsi bugfixes: fix oops when iser is flushing ioMike Christie2006-07-281-20/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we enter recovery and flush the running commands we cannot freee the connection before flushing the commands. Some commands may have a reference to the connection that needs to be released before. iscsi_stop was forcing the term and suspend too early and was causing a oops in iser, so this patch removes those callbacks all together and allows the LLD to handle that detail.

* | | IB/mthca: No userspace SRQs if HCA doesn't have SRQ supportRoland Dreier2006-08-181-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Leave all SRQ methods out of the device's uverbs_cmd_mask if the device doesn't have SRQ support (because of ancient firmware) so that we don't allow userspace to call the driver's create_srq method. This fixes a userspace-triggerable oops caused by ib_uverbs_create_srq() following the device's ->create_srq function pointer, which will be NULL if the device doesn't support SRQs.

* | | IB/core: Fix SM LID/LID change with client reregister setJack Morgenstein2006-08-162-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5, when SM LID change or LID change MAD also has a client reregistration bit set, only CLIENT_REREGISTER event is generated. As a result, the sa_query module and the cache module don't update the port information, and ULPs (e.g. IPoIB) stop working. This is the regression we observe as compared to 2.6.17. Rather than generate multiple events (which would have negative performance impact), let us simply let cache and SA query respond to reregister event in the same way as to LID and SM change events.

* | | IB/mthca: Fix potential AB-BA deadlock with CQ locksRoland Dreier2006-08-112-14/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When destroying a QP, mthca locks both the QP's send CQ and receive CQ. However, the following scenario is perfectly valid: QP_a: send_cq == CQ_x, recv_cq == CQ_y QP_b: send_cq == CQ_y, recv_cq == CQ_x The old mthca code simply locked send_cq and then recv_cq, which in this case could lead to an AB-BA deadlock if QP_a and QP_b were destroyed simultaneously. We can fix this by changing the locking code to lock the CQ with the lower CQ number first, which will create a consistent lock ordering. Also, the second CQ is locked with spin_lock_nested() to tell lockdep that we know what we're doing with the lock nesting. This bug was found by lockdep.

This prevents a crash caused by referring to stale data structures.

This is backwards compatible with previous versions of software and hardware. That is, older software will see a plausible serial number and correct GUID when used with a new board, while newer software will correctly handle an older board.

* | [PATCH] IB/ipath: purge sps_lid and sps_mlid arraysBryan O'Sullivan2006-07-016-36/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The two arrays only had space for 4 units. Also changed from ipath_set_sps_lid() to ipath_set_lid(); the sps was leftover.

* | [PATCH] IB/ipath: rC receive interrupt performance changesBryan O'Sullivan2006-07-016-269/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch separates QP state used for sending and receiving RC packets so the processing in the receive interrupt handler can be done mostly without locks being held. ACK packets are now sent without requiring synchronization with the send tasklet.
