Currently, direct wqe is not supported for wr-list. RoCE driver excludes direct wqe for wr-list by judging whether the number of wr is 1. For a wr-list where the second wr is a length-error atomic wr, the post-send driver handles the first wr and adds 1 to the wr number counter firstly. While handling the second wr, the driver finds out a length error and terminates the wr handle process, remaining the counter at 1. This causes the driver mistakenly judges there is only 1 wr and thus enters the direct wqe process, carrying the current length-error atomic wqe. This patch fixes the error by adding a judgement whether the current wr is a bad wr. If so, use the normal doorbell process but not direct wqe despite the wr number is 1.

bnxt_qplib_rcfw_alloc_sbuf allocates 24 bytes and it is better to fit on stack variables. This way we can avoid unwanted kmalloc call. Call dma_alloc_coherent directly instead of wrapper bnxt_qplib_rcfw_alloc_sbuf. Also, FW expects the side buffer needs to be aligned to BNXT_QPLIB_CMDQE_UNITS(16B). So align the size to have the extra padding bytes. Signed-off-by:

One-element and zero-length arrays are deprecated. So, replace one-element array in struct irdma_qvlist_info with flexible-array member. A patch for this was sent a while ago[1]. However, it seems that, at the time, the changes were partially folded[2][3], and the actual flexible-array transformation was omitted. This patch fixes that. The only binary difference seen before/after changes is shown below: | drivers/infiniband/hw/irdma/hw.o | @@ -868,7 +868,7 @@ | drivers/infiniband/hw/irdma/hw.c:484 (discriminator 2) | size += struct_size(iw_qvlist, qv_info, rf->msix_count); | 55b: imul $0x45c,%rdi,%rdi |- 562: add $0x10,%rdi |+ 562: add $0x4,%rdi which is, of course, expected as it reflects the mistake made while folding the patch I've mentioned above. Worth mentioning is the fact that with this change we save 12 bytes of memory, as can be inferred from the diff snapshot above. Notice that: $ pahole -C rdma_qv_info idrivers/infiniband/hw/irdma/hw.o struct irdma_qv_info { u32 v_idx; /* 0 4 */ u16 ceq_idx; /* 4 2 */ u16 aeq_idx; /* 6 2 */ u8 itr_idx; /* 8 1 */ /* size: 12, cachelines: 1, members: 4 */ /* padding: 3 */ /* last cacheline: 12 bytes */ }; Link: https://lore.kernel.org/linux-hardening/20210525230038.GA175516@embeddedor/ [1] Link: https://lore.kernel.org/linux-hardening/bf46b428deef4e9e89b0ea1704b1f0e5@intel.com/ [2] Link: https://lore.kernel.org/linux-rdma/20210520143809.819-1-shiraz.saleem@intel.com/T/#u [3] Fixes: 44d9e529 ("RDMA/irdma: Implement device initialization definitions") Signed-off-by:Gustavo A.

If a send packet is dropped by the IP layer in rxe_requester() the call to rxe_xmit_packet() can fail with err == -EAGAIN. To recover, the state of the wqe is restored to the state before the packet was sent so it can be resent. However, the routines that save and restore the state miss a significnt part of the variable state in the wqe, the dma struct which is used to process through the sge table. And, the state is not saved before the packet is built which modifies the dma struct. Under heavy stress testing with many QPs on a fast node sending large messages to a slow node dropped packets are observed and the resent packets are corrupted because the dma struct was not restored. This patch fixes this behavior and allows the test cases to succeed.

Currently the attribute cap.max_send_wr and cap.max_recv_wr sent from user-space during create QP are the provider computed SQ/RQ depth as opposed to raw values passed from application. This inhibits computation of an accurate value for max_send_wr and max_recv_wr for this QP in the kernel which matches the value returned in user create QP. Also these capabilities needs to be reported from the driver in query QP. Add support by extending the ABI to allow the raw cap.max_send_wr and cap.max_recv_wr to be passed from user-space, while keeping compatibility for the older scheme. The internal HW depth and shift needed for the WQs needs to be computed now for both kernel and user-mode QPs. Add new helpers to assist with this: irdma_uk_calc_depth_shift_sq, irdma_uk_calc_depth_shift_rq and irdma_uk_calc_depth_shift_wq. Consolidate all the user mode QP setup into a new function irdma_setup_umode_qp which keeps it with its counterpart irdma_setup_kmode_qp. Signed-off-by:

Previously, there was no way to query the number of lanes for a network card, so the same netdev_speed would result in a fixed pair of width and speed. As network card specifications become more diverse, such fixed mode is no longer suitable, so a method is needed to obtain the correct width and speed based on the number of lanes. This patch retrieves netdev lanes and speed from net_device and translates them to IB width and speed. Signed-off-by:
