Subject: [PATCH RFC bpf-next 7/8] bpf, x86: enable KASAN for JITed programs on x86
Date: Mon, 13 Apr 2026 20:28:47 +0200 [thread overview]
Message-ID: <20260413-kasan-v1-7-1a5831230821@bootlin.com> (raw)
In-Reply-To: <20260413-kasan-v1-0-1a5831230821@bootlin.com>
Mark x86 as supporting KASAN checks in JITed programs so that the
corresponding JIT compiler inserts checks on the translated
instructions.
Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com>
