Subject: [PATCH v2 0/5] Small, assorted "hardening" fixes
Date: Thu, 27 Jun 2024 22:46:36 +0200 [thread overview]
Message-ID: <20240627204641.4046184-1-sbrivio@redhat.com> (raw)
All harmless issues as far as I can tell, but nice to fix.
v2:
- in 3/5:
- keep 'skip' in write_remainder() unsigned, and check for
unsigned overflow instead
- refactor sadd_overflow() and ssub_overflow() to use built-ins
with automatic types, take ssize_t arguments, and deal with
different ssize_t type widths
- in 4/5:
- switch l2len in tap_handler_passt() to uint32_t, as it really
is unsigned and 32-bit wide
- return if the length descriptor mismatches, instead of trying
to proceed to the next frame
- add 5/5
Stefano Brivio (5):
conf: Copy up to MAXDNSRCH - 1 bytes, not MAXDNSRCH
tcp_splice: Check return value of setsockopt() for SO_RCVLOWAT
util, lineread, tap: Overflow checks on long signed sums and
subtractions
tap: Discard guest data on length descriptor mismatch
conf: Use the right maximum buffer size for c->sock_path
