Subject: [PATCH rdma-next 00/10] RDMA: Stability and race condition fixes
Date: Wed, 25 Mar 2026 21:00:00 +0200 [thread overview]
Message-ID: <20260325-security-bug-fixes-v1-0-c8332981ad26@nvidia.com> (raw)
This series addresses several stability issues in RDMA core and the
mlx5 driver, mainly around use-after-free conditions in resource
destruction paths and race windows in concurrent create/destroy flows.
Patches 1-5 fix a restrack race window affecting QP, CQ and SRQ
resources in destroy flows.
The core problem is that rdma_restrack_del() was being
called at the end of the destroy routines, leaving a window where the
resource could still be looked up via netlink after vendor-specific
resources were already freed. Two preparatory patches lay the groundwork
followed by three fixes.
Patches 6-7 fix xarray race conditions in the mlx5 SRQ and DCT destroy
paths where a concurrent create can reuse the same firmware object
number right after firmware releases it, causing the destroy path to
incorrectly erase the newly created entry.
The remaining patches are independent fixes.
