Subject: [PATCH v2 02/12] arch/Kconfig: Drop always true condition from RANDOMIZE_KSTACK_OFFSET
Date: Thu, 21 Aug 2025 14:15:39 -0700 [thread overview]
Message-ID: <20250821-bump-min-llvm-ver-15-v2-2-635f3294e5f0@kernel.org> (raw)
In-Reply-To: <20250821-bump-min-llvm-ver-15-v2-0-635f3294e5f0@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
