* IB/mthca: Free correct MPT on error exit from mthca_fmr_alloc()Roland Dreier2008-02-19
| | | | | | | | | When mthca_fmr_alloc() returns an error, it should free the MPT at the index key, not mr->ibmr.lkey, since the lkey has been mangled by hw_index_to_key() and no longer is the real index. This bug causes corruption of the MPT table free bitmap when mthca_fmr_alloc() fails. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IPoIB/cm: Fix ipoib_cm_dev_stop() cleanup when drain times outPradeep Satyanarayana2008-02-19
| | | | | | | | | | | | | | | | Commit efcd9971 ("IPoIB/cm: Factor out ipoib_cm_free_rx_reap_list()") introduced a bug in ipoib_cm_dev_stop() when the receive drain times out. In that case, the function moves all the pending rx stuff into a private list but then calls ipoib_cm_free_rx_reap_list(), which handles a different list. Fix this by moving everything to the rx_reap_list that will actually get freed up. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=906>.

* RDMA/nes: Fix possible array overrunRoland Dreier2008-02-18
| | | | | | | | | | | | | | | | | | | | | | | | In nes_create_qp(), the test if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) { is used to error out if the db_index is too large; however, if the test doesn't trigger, then the index is used as nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp; and mmap_nesqp is declared as struct nes_qp *mmap_nesqp[NES_MAX_USER_WQ_REGIONS]; which leads to an array overrun if the index is exactly equal to NES_MAX_USER_WQ_REGIONS. Fix this by bailing out if the index is greater than or equal to NES_MAX_USER_WQ_REGIONS. This was spotted by the Coverity checker (CID 2162).

* RDMA/cma: Do not issue MRA if user rejects connection requestSean Hefty2008-02-14
| | | | | | | | | | | | | | | | | | | | | | There's an undesirable interaction with issuing MRA requests to increase connection timeouts and the listen backlog. When the rdma_cm receives a connection request, it queues an MRA with the ib_cm. (The ib_cm will send an MRA if it receives a duplicate REQ.) The rdma_cm will then create a new rdma_cm_id and give that to the user, which in this case is the rdma_user_cm. If the listen backlog maintained in the rdma_user_cm is full, it destroys the rdma_cm_id, which in turns destroys the ib_cm_id. The ib_cm_id generates a REJ because the state of the ib_cm_id has changed to MRA sent, versus REQ received. When the backlog is full, we just want to drop the REQ so that it is retried later. Fix this by deferring queuing the MRA until after the user of the rdma_cm has examined the connection request.

* IPoIB: On P_Key change event, reset state properlyJack Morgenstein2008-02-14
| | | | | | | | | | | | | | | | | In P_Key event handling, if the old P_Key is no longer available, the driver must call ipoib_ib_dev_stop() -- just as it does when the P_Key is still available (see procedure __ipoib_ib_dev_flush()). When a P_Key becomes available, the driver will perform ipoib_open(), which assumes that the QP is in RESET, the cm_id has been destroyed/deleted, etc. If ipoib_ib_dev_stop() is not called as described above, then these assumptions will be false, and the attempt to bring the interface up will fail.

| | | | | | | | | | | | | | Commit 9af57b7a ("IB/cm: Add basic performance counters") introduced a bug in how the reference count for cm_class.subsys.kobj was handled: the path that released a device did a kobject_put() on that kobject, but there was no kobject_get() in the path the handles adding a device. So the reference count ended up too low, which leads to bad things. Fix up and simplify the reference counting to avoid this.

* IB/mlx4: Use multiple WQ blocks to post smaller send WQEsJack Morgenstein2008-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | ConnectX HCA supports shrinking WQEs, so that a single work request can be made of multiple units of wqe_shift. This way, WRs can differ in size, and do not have to be a power of 2 in size, saving memory and speeding up send WR posting. Unfortunately, if we do this then the wqe_index field in CQEs can't be used to look up the WR ID anymore, so our implementation does this only if selective signaling is off. Further, on 32-bit platforms, we can't use vmap() to make the QP buffer virtually contigious. Thus we have to use constant-sized WRs to make sure a WR is always fully within a single page-sized chunk. Finally, we use WRs with the NOP opcode to avoid wrapping around the queue buffer in the middle of posting a WR, and we set the NoErrorCompletion bit to avoid getting completions with error for NOP WRs. However, NEC is only supported starting with firmware 2.2.232, so we use constant-sized WRs for older firmware. And, since MLX QPs only support SEND, we use constant-sized WRs in this case. When stamping during NOP posting, do stamping following setting of the NOP WQE valid bit. Signed-off-by: Michael S.

* IB/mthca: Fix and simplify page size calculation in mthca_reg_phys_mr()Roland Dreier2008-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In mthca_reg_phys_mr(), we calculate the page size for the HCA hardware to use to map the buffer list passed in by the consumer. For example, if the consumer passes in [0] addr 0x1000, size 0x1000 [1] addr 0x2000, size 0x1000 then the algorithm would come up with a page size of 0x2000 and a list of two pages, at 0x0000 and 0x2000. Usually, this would work fine since the memory region would start at an offset of 0x1000 and have a length of 0x2000. However, the old code did not take into account the alignment of the IO virtual address passed in. For example, if the consumer passed in a virtual address of 0x6000 for the above, then the offset of 0x1000 would not be used correctly because the page mask of 0x1fff would result in an offset of 0. We can fix this quite neatly by making sure that the page shift we use is no bigger than the first bit where the start of the first buffer and the IO virtual address differ. Also, we can further simplify the code by removing the special case for a single buffer by noticing that it doesn't matter if we use a page size that is too big. This allows the loop to compute the page shift to be replaced with __ffs().

At this time iscsid cannot be running, so the target will drop the session and the boot or shutdown will hang. To handle this and allow us to better control when to check the network this patch moves the nop handling to the kernel.

| * [SCSI] libiscsi: do not block session during logoutMike Christie2008-01-11
| | | | | | | | | | | | | | | | | | There is not need to block the session during logout. Since we are going to fail the commands that were blocked just fail them immediately instead.

| * [SCSI] libiscsi,iser: patch for AHS supportBoaz Harrosh2008-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - The default initialization of hdr_max is the minimum - sizeof(struct iscsi_cmd) - Once this patch goes into iser the default initialization at libiscsi can be removed. - This is not yet full support for AHSs at iser end. But it should be easy. Just allocate more space at iser_desc right after iscsi_hdr. Than at transmission time use ctask->hdr_len to retrieve the total size of all iscsi pdu headers.

| * [SCSI] libiscsi, iscsi_tcp: add device supportMike Christie2008-01-11
| | | | | | | | | | | | | | | | | | | | | | This patch adds logical unit reset support. This should work for ib_iser, but I have not finished testing that driver so it is not hooked in yet. This patch also temporarily reverts the iscsi_tcp r2t write out patch. That code is completely rewritten in this patchset.
