This change replaces traditional functions like 'open' with the POSIX.1-2008 functions like 'openat'. Mostly this is an internal refactoring change, in preparation for further changes to close some races. * gnulib.modules: Add faccessat, linkat, mkfifoat, renameat, symlinkat. Remove save-cwd. * src/Makefile.am (tar_LDADD): Add $(LIB_EACCESS). * tests/Makefile.am (LDADD): Likewise. * src/common.h (chdir_fd): New extern var. * src/compare.c (diff_file, diff_multivol): Use openat instead of open. * src/create.c (create_archive, restore_parent_fd): Likewise. * src/extract.c (create_placeholder_file): Likewise. * src/names.c (collect_and_sort_names): Likewise. * src/update.c (append_file): Likewise. * src/compare.c (diff_symlink): Use readlinkat instead of readlink. * src/compare.c (diff_file): Use chdir_fd instead of AT_FDCWD. * src/create.c (subfile_open, dump_file0): Likewise. * src/extract.c (fd_chmod, fd_chown, fd_stat, set_stat): (repair_delayed_set_stat, apply_nonancestor_delayed_set_stat): Likewise. * src/extract.c (mark_after_links, file_newer_p, extract_dir): (extract_link, apply_delayed_links): Use fstatat rather than stat or lstat. * src/misc.c (maybe_backup_file, deref_stat): Likewise. * src/extract.c (make_directories): Use mkdirat rather than mkdir. Use faccessat rather than access. This fixes a minor permissions bug when tar is running setuid (who would want to do that?!). (open_output_file): Use openat rather than open. In the process, this removes support for Masscomp's O_CTG files, which aren't compatible with openat's signature. Masscomp! Wow! That's a blast from the past. As far as I know, that operating system hasn't been supported for more than 20 years. (extract_link, apply_delayed_links): Use linkat rather than link. (extract_symlink, apply_delayed_links): Use symlinkat rather than symlink. (extract_node): Use mknodat rather than mknod. (extract_fifo): Use mkfifoat rather than mkfifo. (apply_delayed_links): Use unlinkat rather than unlink or rmdir. * src/misc.c (safer_rmdir, remove_any_file): Likewise. * src/unlink.c (flush_deferred_unlinks): Likewise. * src/extract.c (rename_directory): Use renameat rather than rename. * src/misc.c (maybe_backup_file, undo_last_backup): Likewise. * src/misc.c: Don't include <save-cwd.h>; no longer needed now that we're using openat etc. (struct wd): Add member fd. Remove members err and fd. All uses changed. (CHDIR_CACHE_SIZE): New constant. (wdcache, wdcache_count, chdir_fd): New vars. (chdir_do): Use openat rather than save_cwd. Keep the cache up to date. This code won't scale well, but is good enough for now. * src/update.c (update_archive): Use openat + fdopendir + streamsavedir rather than savedir. This file is a placeholder. It will be replaced with the actual ChangeLog by make dist. Run make ChangeLog if you wish to create it earlier.
