Subject: [PATCH bpf-next v8 01/22] bpf: Fix early return in map_check_btf
Date: Thu, 17 Nov 2022 21:54:09 +0530 [thread overview]
Message-ID: <20221117162430.1213770-2-memxor@gmail.com> (raw)
In-Reply-To: <20221117162430.1213770-1-memxor@gmail.com>
Instead of returning directly with -EOPNOTSUPP for the timer case, we
need to free the btf_record before returning to userspace.
Fixes: db559117828d ("bpf: Consolidate spin_lock, timer management into btf_record")
Reported-by: Dan Carpenter <error27@gmail.com>
