Take a closer look here: >> - if (!dounpriv & >> - (gid != (gid_t)-1 && gid != to_sb.st_gid) || >> - (uid != (uid_t)-1 && uid != to_sb.st_uid)) >> + if (!dounpriv && ((gid != (gid_t)-1 && gid != to_sb.st_gid) || >> + (uid != (uid_t)-1 && uid != to_sb.st_uid))) { The intended logic is: if not unpriv and (need to set gid or need to set uid) The actual logic is: if (not unpriv and need to set gid) or need to set uid Luckily it had no practical effect because uid and gid are always -1 when dounpriv is non-zero. I pulled the gid line up to match the formatting of the previous conditional, ten or so lines back. DES -- Dag-Erling Smørgrav - des@FreeBSD.org
