2008-02-26RDMA/nes: Fix use-after-free in nes_create_cq()Glenn Streiff
Just delete the debugging statement so we don't use cqp_request after freeing it. Adrian Bunk flagged this use-after-free issue spotted by the Coverity checker. Signed-off-by: Glenn Streiff <gstreiff@neteffect.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2008-02-25RDMA/nes: Resurrect error path dead codeChien Tung
Adrian Bunk pointed out that a Coverity scan found some apparently dead code in nes_verbs.c that really shouldn't have been dead. The function nes_create_cq() was missing the assignment err = 1; just prior to an iteration that conditionally set err = 0 if a PBL was found for a given virtual CQ. I also noticed we should have been returning -EFAULT on a couple related error paths.

2008-02-18RDMA/nes: Fix possible array overrunRoland Dreier
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).
