Move the initialization of ipoib_neigh's skb_queue into ipoib_neigh_alloc(), since commit 2745b5b7 ("IPoIB: Fix skb leak when freeing neighbour") will make iterate over the skb_queue to free any packets left over when freeing the ipoib_neigh structure. This fixes a crash when freeing ipoib_neigh structures allocated in ipoib_mcast_send(), which otherwise don't have their skb_queue initialized. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

During connection establishment, the passive side of a connection can receive messages from the active side before the connection event has been delivered to the user. Allow the passive side to send messages in response to received data before the event is delivered. To handle the case where the connection messages are lost, a new rdma_notify() function is added that users may invoke to force a connection into the established state.

Commit 51f65ebc ("IB/ipath - program intconfig register using new HT irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI Express HCAs, because for those HCAs, the driver uses the value of pdev->irq before pci_enable_msi() and ends up getting a totally bogus IRQ number. Fix this by using the value of pdev->irq after pci_enable_msi(). Signed-off-by: NRoland Dreier <rolandd@cisco.com>

ib_flush_fmr_pool() stashes away the request generation number properly, but then goes ahead and rereads it every time it tests whether the flush generation number has caught up. This means that there is a theoretical possibility of livelock, if the request generation number keeps getting bumped and the flush generation number never catches up. The fix is simple: use the request generation number read at the beginning of the function. Also, atomic_inc() followed by atomic_read() can be replaced with atomic_int_return(). There's no real requirement for atomicity here but we might as well shrink the code. This bug was discovered using David Binderman's list of "set but never used" warnings from icc.

This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

ib_ucm_cleanup_events() holds file_mutex while calling ib_destroy_cm_id(). This can deadlock since ib_destroy_cm_id() flushes event handlers, and ib_ucm_event_handler() needs file_mutex, too. Therefore, drop the file_mutex during the call to ib_destroy_cm_id(). Signed-off-by: NMichael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

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.

It is possible to swap the CQs used for send_cq and recv_cq when creating two different QPs.

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.

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).

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.
