- #286: --numeric-ids is a mapping modifier only; it no longer activates
chown by itself (identity_active_enabled/owner/group predicates), and
--fake-super stores the resolved mapping instead of real-chowning.
- #286: apply owner/group to directories via the deferred directory
metadata path; capture+transmit+apply directory xattrs/ACLs (-aX/-aA),
including default ACLs, in STATUS_MKDIR/STATUS_DIR_TIMES.
- #294: --usermap/--groupmap support inclusive ranges, '*', empty FROM
(unnamed ids), and receiver-side TO name resolution; --chown mixing with
a same-side map is rejected like rsync.
- Protocol 2.22.0 -> 2.23.0 (map wire entry gains from_hi + to_name;
dir frames gain a bounded xattr block).
Add two libFuzzer harnesses (GLOBbed from tests/fuzz/*.c) and deterministic
P8 config-frame receive tests:
- fuzz_config_receive.c drives config_receive() from arbitrary bytes. It
captures one canonical valid frame with the production sender and feeds the
receiver four shapes: raw bytes, valid-version-prefix + fuzz bytes, valid
frame minus the P8 tail (super_mode + copy-as) + fuzz bytes, and valid frame
minus the usermap count + fuzz bytes. This reaches the --super/--copy-as and
huge/negative map-count paths that random bytes cannot get through the
preceding wire-bool gate.
- fuzz_identity_parse.c fuzzes identity_parse_copy_as/map/chown plus the
identity_wire_valid/identity_ownership_requested predicates on a fresh
config per input.
- test_fuzz_smoke.c gains deterministic malformed-frame cases: out-of-range
super_mode, negative/extreme copy-as ids, non-bool copy-as presence, tail
truncation, huge/negative usermap counts, version mismatch and a
wrong-order field after the version gate.
Unit build (STRICT_WARNINGS) and the fuzz build are clean; both targets run
3000+ iterations with no crash. No production code changed.
Capture+transmit source atime (pre-read stat; O_NOATIME sender guard) and birth
time (statx STATX_BTIME); receiver restores atime with mtime (crtime not settable
portably -> transmitted, explicitly not applied). --open-noatime is client-only.
-O/-J documented as accepted no-ops (FastSync never preserves dir/symlink times).
Wire: metadata frame gains atime/crtime val+sec+nsec; PROTOCOL_VERSION
2.11.0->2.12.0. Review fixes: gate atime capture to Linux (no epoch clobber on
non-Linux), close fd on fdopen failure, honest -O/-J status (Compat no-op).
