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
