The branch main has been updated by kib: URL: https://cgit.FreeBSD.org/src/commit/?id=428da7d65b1c41c81a8786f66c1ce2f4242ac8bb commit 428da7d65b1c41c81a8786f66c1ce2f4242ac8bb Author: Konstantin Belousov <kib@FreeBSD.org> AuthorDate: 2026-04-20 20:02:13 +0000 Commit: Konstantin Belousov <kib@FreeBSD.org> CommitDate: 2026-05-10 14:53:20 +0000 Add O_SYMLINK emulation for MacOSX partial compatibility, defined as O_PATH | O_NOFOLLOW. fstat(2) and freadlink(3) works on the resulting file descriptors, but reads on the regular file do not. More complete but more hackish version was developed but deemed too hackish.
