2012-09-14RDMA/ocrdma: Fix CQE expansion of unsignaled WQEParav Pandit1-4/+4
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 Dreier1-8/+8
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 Dreier1-1/+3
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>

2012-07-07RDMA/ocrdma: Fix assignment of max_srq_sge in device queryRoland Dreier1-1/+1
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 Carpenter1-1/+1
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 GID table for vlan and eventsParav Pandit1-29/+34
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 Dreier2-9/+22
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: Tiny locking cleanupDan Carpenter1-5/+5
We only need to disable the IRQs one time. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> [ Rename "wq_flags" to more conventional "flags." - Roland ] Signed-off-by: Roland Dreier <roland@purestorage.com>
2012-05-08RDMA/ocrdma: Fix check for NULL instead of IS_ERRDan Carpenter1-2/+2
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 Levin2-16/+23
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 Dreier1-1/+3
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 Dreier2-3/+4
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.
