Subject: [PATCH 0/6] pack-bitmap: miscellaneous mmap read hardening
Date: Mon, 20 Mar 2023 16:02:37 -0400 [thread overview]
Message-ID: <cover.1679342296.git.me@ttaylorr.com> (raw)
This short series has a few minor refactorings and hardenings I noticed
while reading the pack-bitmap.c code recently.
The series is structured as follows:
- The first three are cleanups to the read_be32() and read_u8()
functions that could be taken on their own.
- The last three replace manually reading from `bitmap_git->map` and
adjusting `bitmap_git->map_pos` accordingly with a new
`bitmap_index_seek()` wrapper that accomplishes the same with
additional bounds- and overflow-checking.
Thanks in advance for your review.
Taylor Blau (6):
pack-bitmap.c: hide bitmap internals in `read_u8()`
pack-bitmap.c: hide bitmap internals in `read_be32()`
pack-bitmap.c: drop unnecessary 'inline's
pack-bitmap.c: factor out manual `map_pos` manipulation
pack-bitmap.c: use `bitmap_index_seek()` where possible
pack-bitmap.c: factor out `bitmap_index_seek_commit()`
