Subject: [PATCH] RDMA/ocrdma: Fix potential EQ table leak
Date: Thu, 12 Nov 2026 21:59:12 +0800 [thread overview]
Message-ID: <20261112-88a3a7ff32-rdma-ocrdma@mail.sdu.edu.cn> (raw)
EQ teardown destroys the individual queues but leaves their dynamically
allocated table behind. Free the table after all EQs have been destroyed
and reset its pointer and count.
This issue was found by our static analysis tool under development.
Fixes: fe2caefcdf58 ("RDMA/ocrdma: Add driver for Emulex OneConnect IBoE RDMA adapter")
