It would then unconditionally try return a flush completion via qib_send_complete() for an invalid wqe, or worse a valid one that is not queued. The panic results when the completion code tries to maintain an MR reference count for a NULL MR. This fix modifies logic to only send one completion per qib_make_rc_req() call and changing the completion status from IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress. The outer loop will call as many times as necessary to flush the queue.

2011-11-04IB/iser: DMA unmap TX bufs used for iSCSI/iSER headersOr Gerlitz
The current driver never does DMA unmapping on these buffers. Fix that by adding DMA unmapping to the task cleanup callback, and DMA mapping to the task init function (drop the headers_initialized micro-optimization).

2011-11-04IB/iser: Use separate buffers for the login request/responseOr Gerlitz
The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each.

2011-11-03IB/mthca: Fix buddy->num_free allocation sizeRoland Dreier
The num_free field of mthca_buddy has a type of array of unsigned int while it was allocated as an array of pointers. On 64-bit platforms this allocates twice more than required. Fix this by allocating the correct size for the type. This is the same bug just fixed in mlx4 by Eli Cohen <eli@mellanox.co.il>. Signed-off-by: Roland Dreier <roland@purestorage.com>

2011-11-03net: Add back alignment for size for __alloc_skbTony Lindgren
Commit 87fb4b7b533073eeeaed0b6bf7c2328995f6c075 (net: more accurate skb truesize) changed the alignment of size.

Simon Kirby reported lockdep warnings and following messages : [104661.897577] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? [104661.923653] huh, entered softirq 3 NET_RX ffffffff81613740 preempt_count 00000101, exited with 00000102? Problem comes from commit 0e734419 (ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.) If inet_csk_route_child_sock() returns NULL, we should release socket lock before freeing it. Another lock imbalance exists if __inet_inherit_port() returns an error since commit 093d282321da ( tproxy: fix hash locking issue when using port redirection in __inet_inherit_port()) a backport is also needed for >= 2.6.37 kernels.

Misha Labjuk reported panics occurring in l2tp_recv_dequeue() If we release reorder_q.lock, we must not keep a dangling pointer (tmp), since another thread could manipulate reorder_q. Instead we must restart the scan at beginning of list.
