2023-08-20RDMA/mlx5: Handles RoCE MACsec steering rules addition and deletionPatrisious Haddad
Add RoCE MACsec rules when a gid is added for the MACsec netdevice and handle their cleanup when the gid is removed or the MACsec SA is deleted. Also support alias IP for the MACsec device, as long as we don't have more ips than what the gid table can hold. In addition handle the case where a gid is added but there are still no SAs added for the MACsec device, so the rules are added later on when the SAs are added.

2023-08-20RDMA/mlx5: Implement MACsec gid addition and deletionPatrisious Haddad
Handle MACsec IP ambiguity issue, since mlx5 hw can't support programming both the MACsec and the physical gid when they have the same IP address, because it wouldn't know to whom to steer the traffic. Hence in such case we delete the physical gid from the hw gid table, which would then cause all traffic sent over it to fail, and we'll only be able to send traffic over the MACsec gid.

2023-08-19RDMA/irdma: Prevent zero-length STAG registrationChristopher Bednarz
Currently irdma allows zero-length STAGs to be programmed in HW during the kernel mode fast register flow. Zero-length MR or STAG registration disable HW memory length checks. Improve gaps in bounds checking in irdma by preventing zero-length STAG or MR registrations except if the IB_PD_UNSAFE_GLOBAL_RKEY is set. This addresses the disclosure CVE-2023-25775.

2023-08-07net/mlx5: Allocate completion EQs dynamicallyMaher Sanalla
This commit enables the dynamic allocation of EQs at runtime, allowing for more flexibility in managing completion EQs and reducing the memory overhead of driver load. Whenever a CQ is created for a given vector index, the driver will lookup to see if there is an already mapped completion EQ for that vector, if so, utilize it. Otherwise, allocate a new EQ on demand and then utilize it for the CQ completion events. Add a protection lock to the EQ table to protect from concurrent EQ creation attempts. While at it, replace mlx5_vector2irqn()/mlx5_vector2eqn() with mlx5_comp_eqn_get() and mlx5_comp_irqn_get() which will allocate an EQ on demand if no EQ is found for the given vector.

2023-08-07RDMA/hns: Fix incorrect post-send with direct wqe of wr-listJunxian Huang
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.

2023-08-03RDMA/irdma: Replace one-element array with flexible-array memberGustavo A. R. Silva
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.

2023-07-30RDMA/irdma: Allow accurate reporting on QP max send/recv WRSindhu Devale
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.
