From: "Jason A. Donenfeld" <Jason@zx2c4.com> stable inclusion from stable-v5.10.84 commit 4caf965f6cbecb73e8394ab59310309667e3e8ec bugzilla: 186030 https://gitee.com/openeuler/kernel/issues/I4QV2F Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 03ff1b1def73f817e196bf96ab36ac259490bd7c upstream. 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.
