From cf1e18aa7a357185c0a1abd56963c777f716d306 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Mon, 29 Nov 2021 10:39:21 -0500 Subject: [PATCH] UPSTREAM: wireguard: selftests: increase default dmesg log size The selftests currently parse the kernel log at the end to track potential memory leaks. With these tests now reading off the end of the buffer, due to recent optimizations, some creation messages were lost, making the tests think that there was a free without an alloc. Fix this by increasing the kernel log size. Fixes: 24b70eeeb4f4 ("wireguard: use synchronize_net rather than synchronize_rcu") Signed-off-by: Jason A.
