Subject: [PATCH v3 0/4] net/axgbe: fix resource leaks and OOB access
Date: Thu, 18 Jun 2026 10:21:55 -0700	[thread overview]
Message-ID: <20260618172544.338758-1-stephen@networkplumber.org> (raw)
In-Reply-To: <20260218164324.915065-1-stephen@networkplumber.org>

A code review of the axgbe PMD turned up several correctness bugs,
most of them in resource management on the device initialization
error paths, plus an out-of-bounds descriptor ring access.

v3:
  - Patch 1: consolidate the error-path cleanup 
  - Patch 2: split Rx buffer setup into two passes

Stephen Hemminger (4):
  net/axgbe: fix resource leaks in device init error paths
  net/axgbe: fix Rx queue leak on descriptor init failure
  net/axgbe: destroy mutexes on device close
  net/axgbe: fix descriptor status out-of-bounds access
