Subject: [PATCH v3 0/5] Enable -Warray-bounds and -Wzero-length-bounds
Date: Fri, 27 Aug 2021 09:30:10 -0700 [thread overview]
Message-ID: <20210827163015.3141722-1-keescook@chromium.org> (raw)
v3:
- fix typo in treewide conversion (u8 should have been __u8)
- improve changelog for DECLARE_FLEX_ARRAY patch
- add acks/reviews
v2: https://lore.kernel.org/lkml/20210826050458.1540622-1-keescook@chromium.org/
v1: https://lore.kernel.org/lkml/20210818081118.1667663-1-keescook@chromium.org/
Hi,
In support of the improved buffer overflow detection for memcpy(),
this enables -Warray-bounds and -Wzero-length-bounds globally. Mostly
it involves some struct member tricks with the new DECLARE_FLEX_ARRAY()
macro. Everything else is just replacing stacked 0-element arrays
with actual unions in two related treewide patches. There is one set of
special cases that were fixed separately[1] and are needed as well.
I'm expecting to carry this series with the memcpy() series in my
"overflow" tree. Reviews appreciated! :)
Thanks!
-Kees
