Subject: [dpdk-stable] [PATCH v2 2/2] net/ice: fix leak on thread termination
Date: Tue, 11 May 2021 13:33:58 +0200
Message-ID: <20210511113358.2485-3-david.marchand@redhat.com> (raw)
In-Reply-To: <20210511113358.2485-1-david.marchand@redhat.com>

A terminated pthread should be joined or detached so that its associated
resources are released.

The "ice-reset-<vf_id>" threads are used to service some reset task in the
background, but they are never joined by the thread that created them.
The easiest solution is to detach new threads.

The Windows EAL did not provide a pthread_detach wrapper but there is no
resource to release for Windows threads, so add an empty wrapper.

Fixes: 3b3757bda3c3 ("net/ice: get VF hardware index in DCF")
