Subject: [PATCH 00/23] misc: Remove variable-length arrays on the stack
Date: Wed, 5 May 2021 23:10:24 +0200 [thread overview]
Message-ID: <20210505211047.1496765-1-philmd@redhat.com> (raw)
Hi,
This series is inspired by Gerd Hoffmann and CVE-2021-3527.
It removes all uses of variable-length arrays in the repository,
then enable the '-Wvla' warning to avoid new code using vla
to be merged.
Mostly trivial patches using GLib autofree.
Please review,
Phil.
