2012-09-14RDMA/ocrdma: Fix CQE expansion of unsignaled WQEParav Pandit
Fix CQE expansion of unsignaled WQE -- don't expand the CQE when the WQE index of the completed CQE matches with last pending WQE (tail) in the queue. Signed-off-by: Parav Pandit <parav.pandit@emulex.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-08-10RDMA/ocrdma: Don't call vlan_dev_real_dev() for non-VLAN netdevsRoland Dreier
If CONFIG_VLAN_8021Q is not set, then vlan_dev_real_dev() just goes BUG(), so we shouldn't call it unless we're actually dealing with a VLAN netdev. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-07-27RDMA/ocrdma: Fix check of GSI CQsRoland Dreier
It looks like one check was accidentally duplicated, and the other 3 checks were left out. This was detected by scripts/coccinelle/tests/doubletest.cocci: drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:895:6-54: duplicated argument to && or || Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

Instead of testing defined(CONFIG_IPV6) || defined(CONFIG_IPV6_MODULE) Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-07-07RDMA/ocrdma: Fix assignment of max_srq_sge in device queryRoland Dreier
We want to set attr->max_srq_sge to dev->attr.max_srq_sge, not to itself. This was detected by Coverity (CID 709210). Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-06-14RDMA/ocrdma: Fix off by one in ocrdma_query_gid()Dan Carpenter
The dev->sgid_tbl[] array is allocated in ocrdma_alloc_resources(). It has OCRDMA_MAX_SGID elements so the test here is off by one. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-06-11RDMA/ocrdma: Fixed RQ error CQE pollingParav Pandit

2012-06-11RDMA/ocrdma: Fixed GID table for vlan and eventsParav Pandit
1. Fix reporting GID table addition events. 2. Enable vlan based GID entries only when VLAN is enabled at compile time (test CONFIG_VLAN_8021Q / CONFIG_VLAN_8021Q_MODULE). Signed-off-by: Parav Pandit <parav.pandit@emulex.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

2012-05-08RDMA/ocrdma: Fix build with IPV6=nRoland Dreier
When IPV6 is not enabled: ERROR: "register_inet6addr_notifier" [drivers/infiniband/hw/ocrdma/ocrdma.ko] undefined! ERROR: "unregister_inet6addr_notifier" [drivers/infiniband/hw/ocrdma/ocrdma.ko] undefined! Fix this by wrapping the inet6 calls in #ifdef IPV6. Also make the ocrdma module depend on (IPV6 || IPV6=n) to forbid the case of modular ipv6 but built-in ocrdma (which can't work, because ocrdma calls ipv6 functions).

2012-05-08RDMA/ocrdma: Fix check for NULL instead of IS_ERRDan Carpenter
The ocrdma_alloc_lkey() function never returns NULL pointers -- it returns ERR_PTRs. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-05-08RDMA/ocrdma: Don't sleep in atomic notifier handlerSasha Levin
Events sent to ocrdma_inet6addr_event() are sent from an atomic context, therefore we can't try to lock a mutex within the notifier callback. We could just switch the mutex to a spinlock since all it does it protect a list, but I've gone ahead and switched the list to use RCU instead. I couldn't fully test it since I don't have IB hardware, so if it doesn't fully work for some reason let me know and I'll switch it back to using a spinlock.

2012-05-08RDMA/ocrdma: Set event's device member in ocrdma_dispatch_ibevent()Roland Dreier
We need to set ib_evt.device, or else ib_dispatch_event() will crash when we call it for unaffiliated events (and consumers may get confused in their QP/CQ/SRQ event handler for affiliated events). Also fix sparse warning: drivers/infiniband/hw/ocrdma/ocrdma_hw.c:678:36: warning: Using plain integer as NULL pointer There's no need to clear ib_evt, since every member is initialized.

2012-05-08RDMA/ocrdma: Fix warnings about uninitialized variablesRoland Dreier
First, fix drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function 'ocrdma_alloc_pd': drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:371:17: warning: 'dpp_page_addr' may be used uninitialized in this function [-Wuninitialized] drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:337:6: note: 'dpp_page_addr' was declared here which seems that it may border on a bug (the call to ocrdma_del_mmap() might conceivably do bad things if pd->dpp_enabled is not set and dpp_page_addr ends up with just the wrong value). Also take care of: drivers/infiniband/hw/ocrdma/ocrdma_hw.c: In function 'ocrdma_init_hw': drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2587:5: warning: 'status' may be used uninitialized in this function [-Wuninitialized] drivers/infiniband/hw/ocrdma/ocrdma_hw.c:2549:17: note: 'status' was declared here which is only real if num_eq == 0, which should be impossible.
