Subject: [dpdk-stable] [PATCH 2/2] net/ice: fix leak on thread termination
Date: Thu,  6 May 2021 11:44:52 +0200
Message-ID: <20210506094452.1689-3-david.marchand@redhat.com> (raw)
In-Reply-To: <20210506094452.1689-1-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.

Fixes: 3b3757bda3c3 ("net/ice: get VF hardware index in DCF")
Cc: stable@dpdk.org
