Subject: [PATCH] net/mlx5: destroy DR domains after ASO close
Date: Wed, 11 Nov 2026 15:34:52 +0200	[thread overview]
Message-ID: <20261111133456.49554-1-bingz@nvidia.com> (raw)

ASO age, meter and connection tracking actions are created in the
shared DR domains and released only when the ASO management is
closed. That close runs in mlx5_free_shared_dev_ctx(), while the
domains are destroyed earlier in mlx5_os_free_shared_dr(). Freeing
a domain-bound action after the domain is gone crashes on close.

The domains belong to the shared context, as the ASO managers do.
Destroy them in mlx5_free_shared_dev_ctx() after the ASO managers.
One port close then cannot drop them while another port still uses
the shared context.

Fixes: f935ed4b645a ("net/mlx5: support flow hit action for aging")
Fixes: c99b4f8bc2f1 ("net/mlx5: support ASO meter action")
Fixes: ce12974cce72 ("net/mlx5: fix ASO CT object release")
