- --chmod no longer implies --preserve-perms; repeated --chmod options accumulate, and D/F/X selectors plus s/t special bits are supported with rsync's exact parse_chmod/tweak_mode semantics. - Stop masking group/other write and setuid/setgid/sticky: -p copies the source mode exactly, no-p new entries use source&~umask, directories keep setgid/sticky, and special nodes follow the same rules. - Apply ownership before mode on the fd path so a chown cannot clear the setuid/setgid bits -p just restored (rsync order). - Update unit and integration tests, including differential checks against rsync 3.4.1.
