* RDMA/ocrdma: Fix several stack info leaksDan Carpenter2013-07-301-1/+4
| | | | | | | | | A grab bag of places which don't properly initialize stack data. I removed one place which cleared ".rsvd" because it's not needed now that I have added a memset() earlier in the function.

| | | | | | | | 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>

* RDMA/ocrdma: Fix build with IPV6=nRoland Dreier2012-05-082-9/+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).

* RDMA/ocrdma: Don't sleep in atomic notifier handlerSasha Levin2012-05-082-16/+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.

| | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | 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.
