Hello: This patch was applied to netdev/net.git (main) by Jakub Kicinski [off-list ref]: On Thu, 4 Jun 2026 14:19:46 +0200 you wrote:
After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovs_mutex. However, error cleanups still follow the classical reversed order, assuming "reply" is allocated before locking: it is freed after unlocking. If "reply" allocation happens after locking the mutex and it fails, "reply" is left with an ERR_PTR, and execution jumps to the correspondent cleanup stage which will try to free an invalid pointer. [...]
