2006-11-29IB/cm: Fix automatic path migration supportSean Hefty
The ib_cm_establish() function is replaced with a more generic ib_cm_notify(). This routine is used to notify the CM that failover has occurred, so that future CM messages (LAP, DREQ) reach the remote CM. (Currently, we continue to use the original path) This bumps the userspace CM ABI. New alternate path information is captured when a LAP message is sent or received. This allows QP attributes to be initialized for the user when a new path is loaded after failover occurs.

2006-11-29IPoIB: Fix skb leak when freeing neighbourMichael S. Tsirkin
ipoib_neigh_free() is sometimes called while neighbour is still alive, so it might still have queued skbs. Fix skb leak in this case. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-11-29IB/srp: Fix memory leak on reconnectVu Pham
SRP reallocates the IU buffers for tx_ring and rx_ring without freeing the old buffers when it reconnects to a target. Fix this by keeping the old IU buffers around. Signed-off-by: Vu Pham <vu@mellanox.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-11-29RDMA/addr: Fix some cancellation problems in process_req()Krishna Kumar
Fix following problems in process_req() relating to cancellation: - Function is wrongly doing another addr_remote() when cancelled, which is not required. - Make failure reporting immediate by using time_after_eq(). - On cancellation, -ETIMEDOUT was returned to the callback routine instead of the more appropriate -ECANCELLED (users getting notified may want to print/return this status, eg ucma_event_handler).

2006-11-29RDMA/amso1100: Prevent deadlock in destroy QPKrishna Kumar
It is possible to swap the CQs used for send_cq and recv_cq when creating two different QPs. If these two QPs are then destroyed at the same time, an AB-BA deadlock can occur because the CQ locks are taken our of order. Fix this by always taking CQ locks in a fixed order.

2006-11-29IB/mthca: Fix initial SRQ logsize for mem-free HCAsJack Morgenstein
When initializing an mthca SRQ, the log_srq_size field should be the log of the number of SRQ WQEs, not the log of the number of bytes in the SRQ. This affects only mthca drivers for memfree HCAs which set the initial srq wqe counter (in the SW2HW transition) to a non-zero value.

2006-11-29IB/ehca: Use WQE offset instead of WQE addr for pending work reqsHoang-Nam Nguyen
This is a patch for ehca to fix a bug in prepare_sqe_to_rts(), which used WQE address to iterate pending work requests. This might cause an access violation since the queue pages can not be assumed to follow each other consecutively. Thus, this patch introduces a few queue functions to determine WQE offset based on its address and uses WQE offset to iterate the pending work requests.

2006-11-29RDMA/iwcm: Fix comment for iwcm_deref_id() to match codeKrishna Kumar
In iwcm_deref_id(), the comment says : "If the last reference is being removed and iw_destroy_cm_id is waiting, wake up the waiting thread". The second part of the comment, "and iw_destroy_cm_id is waiting," is wrong, since this function either wakes the waiter already waiting in iwcm_deref_id, or enables it (so that when wait_for_completion() is performed later, it will immediately return).

2006-11-29RDMA/iwcm: Fix memory leakKrishna Kumar
If we get IW_CM_EVENT_CONNECT_REQUEST message and encounter an error (not in the LISTEN state, cannot create an id, cannot alloc work_entry, etc), then the memory allocated by cm_event_handler() in the event->private_data gets leaked. Since cm_work_handler has already put the event on the work_free_list, this allocated memory is leaked. High backlog value can allow DoS attacks.

2006-11-29RDMA/iwcm: Fix memory corruption bug in cm_work_handler()Krishna Kumar
Possible memory corruption scenario: after putting the work entry back on the work_free_list, we call process_event() which dereferences work->event, which could have been modified to another value meanwhile.

2006-11-29IB/mthca: Fix section mismatchesRoland Dreier
Commit b3b30f5e ("IB/mthca: Recover from catastrophic errors") introduced some section mismatch breakage, because the error recovery code tears down and reinitializes the device, which calls into lots of code originally marked __devinit and __devexit from regular .text.

2006-11-29RDMA/addr: Use time_after_eq() instead of time_after() in queue_req()Krishna Kumar
In queue_req(), use time_after_eq() instead of time_after() for following reasons : - Improves insert time if multiple entries with same time are present. - set_timeout need not be called if entry with same time is added to the list (and that happens to be the entry with the smallest time), saving atomic/locking operations. - Earlier entries with same time are deleted first (fifo).

2006-11-28[NET]: Fix MAX_HEADER setting.David S. Miller
MAX_HEADER is either set to LL_MAX_HEADER or LL_MAX_HEADER + 48, and this is controlled by a set of CONFIG_* ifdef tests. It is trying to use LL_MAX_HEADER + 48 when any of the tunnels are enabled which set hard_header_len like this: dev->hard_header_len = LL_MAX_HEADER + sizeof(struct xxx); The correct set of tunnel drivers which do this are: ipip ip_gre ip6_tunnel sit so make the ifdef test match.
