From 9ab20f76ae9fad55ebaf36bdff04aea1c2552374 Mon Sep 17 00:00:00 2001 From: Saravanan Vajravel Date: Wed, 18 Sep 2024 20:05:57 -0700 Subject: [PATCH] RDMA/bnxt_re: Fix incorrect AVID type in WQE structure Driver uses internal data structure to construct WQE frame. It used avid type as u16 which can accommodate up to 64K AVs. When outstanding AVID crosses 64K, driver truncates AVID and hence it uses incorrect AVID to WR. This leads to WR failure due to invalid AV ID and QP is moved to error state with reason set to 19 (INVALID AVID). When RDMA CM path is used, this issue hits QP1 and it is moved to error state Fixes: 1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver") Link: https://patch.msgid.link/r/1726715161-18941-3-git-send-email-selvin.xavier@broadcom.com Reviewed-by: Selvin Xavier Reviewed-by: Chandramohan Akula Signed-off-by: Saravanan Vajravel Signed-off-by: Kalesh AP Signed-off-by: Selvin Xavier Signed-off-by: Jason Gunthorpe Signed-off-by: Leon Romanovsky --- drivers/infiniband/hw/bnxt_re/qplib_fp.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/infiniband/hw/bnxt_re/qplib_fp.h b/drivers/infiniband/hw/bnxt_re/qplib_fp.h index b62df8701950..820611a23943 100644 --- a/drivers/infiniband/hw/bnxt_re/qplib_fp.h +++ b/drivers/infiniband/hw/bnxt_re/qplib_fp.h @@ -170,7 +170,7 @@ struct bnxt_qplib_swqe { }; u32 q_key; u32 dst_qp; - u16 avid; + u32 avid; } send; /* Send Raw Ethernet and QP1 */
