Subject: [PATCH bpf v2 15/15] selftests/bpf: Don't override SIGSEGV handler with ASAN
Date: Tue, 17 Feb 2026 16:30:41 -0800 [thread overview]
Message-ID: <20260218003041.1156774-16-ihor.solodrai@linux.dev> (raw)
In-Reply-To: <20260218003041.1156774-1-ihor.solodrai@linux.dev>
test_progs has custom SIGSEGV handler, which interferes with the
address sanitizer [1]. Add an #ifndef to avoid this.
