Subject: [PATCH rdma-next v2 02/11] RDMA/mlx5: Remove raw RSS QP restrack tracking
Date: Mon, 6 Apr 2026 12:11:13 +0300 [thread overview]
Message-ID: <20260406-security-bug-fixes-v2-2-ee8815fa81b7@nvidia.com> (raw)
In-Reply-To: <20260406-security-bug-fixes-v2-0-ee8815fa81b7@nvidia.com>
From: Patrisious Haddad <phaddad@nvidia.com>
Raw RSS QP restrack tracking wasn't working to begin with as it was
only tracking the first raw RSS QP which was added, since at creation
the raw RSS QP number is reserved so the QP number for this qp type
was always zero.
The following raw RSS QP additions were always failing silently.
Hence remove the tracking for the raw RSS QP, support can be added
later for it if needed by using the tirn for tracking.
Fixes: 968f0b6f9c01 ("RDMA/mlx5: Consolidate into special function all create QP calls")
