2017-01-12RDMA/i40iw: use designated initializersKees Cook1-17/+17
Prepare to mark sensitive kernel structures for randomization by making sure they're using designated initializers. These were identified during allyesconfig builds of x86, arm, and arm64, with most initializer fixes extracted from grsecurity.

2016-12-22i40iw: Set 128B as the only supported RQ WQE sizeChien Tin Tung1-5/+12
RQ WQE size other than 128B is not supported. Correct RQ size calculation to use 128B only. Since this breaks ABI, add additional code to provide compatibility with v4 user provider, libi40iw.

2016-12-05i40iw: Fix incorrect assignment of SQ headHenry Orosco1-6/+4
The SQ head is incorrectly incremented when the number of WQEs required is greater than the number available. The fix is to use the I40IW_RING_MOV_HEAD_BY_COUNT macro. This checks for the SQ full condition first and only if SQ has room for the request, then we move the head appropriately.

2016-12-05i40iw: Remove checks for more than 48 bytes inline dataHenry Orosco1-5/+1
Remove dead code, which isn't executed because we return error if the data size is greater than 48 bytes. Inline data size greater than 48 bytes isn't supported and the maximum WQE size is 64 bytes.

2016-12-05i40iw: Optimize inline data copyHenry Orosco1-14/+10
Use memcpy for inline data copy in sends and writes instead of byte by byte copy. Signed-off-by: Mustafa Ismail <mustafa.ismail@intel.com> Signed-off-by: Henry Orosco <henry.orosco@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2016-08-02i40iw: Remove unnecessary check for moving CQ headMustafa Ismail1-5/+1
In i40iw_cq_poll_completion, we always move the tail. So there is no reason to check for overflow everytime we move the head. Signed-off-by: Mustafa Ismail <mustafa.ismail@intel.com> Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-08-02i40iw: Remove unnecessary parameter to i40iw_cq_poll_completionMustafa Ismail1-7/+4
Post_cq parameter passed to i40iw_cq_poll_completion is always true; so remove. Signed-off-by: Mustafa Ismail <mustafa.ismail@intel.com> Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2016-04-28RDMA/i40iw: Fix for checking if the QP is destroyedTatyana Nikolova1-0/+5
Fix for checking if the QP associated with a completion has been destroyed while processing CQ elements. If that is the case, move the CQ head to the next element and continue completion processing.

2016-04-28RDMA/i40iw: Fixes for WQE alignmentShiraz Saleem1-2/+16
Invalidation after every WQE write is changed to invalidate only if required. NOPs are padded so that WQE writes are aligned to 64B boundary.

2016-04-28RDMA/i40iw: Correct QP size calculationIsmail, Mustafa1-49/+31
Include inline data size as part of SQ size calculation. RQ size calculation uses only number of SGEs and does not support 96 byte WQE size. Signed-off-by: Mustafa Ismail <mustafa.ismail@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
