Subject: [PATCH 02/10] arch/Kconfig: Drop always true condition from RANDOMIZE_KSTACK_OFFSET
Date: Mon, 18 Aug 2025 11:57:18 -0700 [thread overview]
Message-ID: <20250818-bump-min-llvm-ver-15-v1-2-c8b1d0f955e0@kernel.org> (raw)
In-Reply-To: <20250818-bump-min-llvm-ver-15-v1-0-c8b1d0f955e0@kernel.org>
Now that the minimum supported version of LLVM for building the kernel
has been bumped to 15.0.0, the second depends line in
RANDOMIZE_KSTACK_OFFSET is always true, so it can be removed.

The kernel stack offset can be randomized (after pt_regs) by
roughly 5 bits of entropy, frustrating memory corruption
