Subject: [PATCH bpf-next v2 0/3] bpf/verifier: Use kmalloc_size_roundup() to match ksize() usage
Date: Fri, 28 Oct 2022 19:54:29 -0700 [thread overview]
Message-ID: <20221029024444.gonna.633-kees@kernel.org> (raw)
v2:
- split up patch into logical changes
- simplify copy_array, which can use ksize() directly
v1: https://lore.kernel.org/all/20221018090550.never.834-kees@kernel.org/
Hi,
Here's the next version of removing the BPF verifier's dependency on the
side-effects of ksize(), so we can remove the special handling needed
for KASAN, UBSAN_BOUNDS, nor FORTIFY_SOURCE in ksize().
Thanks,
-Kees
