* NEWS: Note the change. Mention dirfd and fdopendir. * gnulib.modules: Add dirfd and fdopendir. The code was already using fdopendir; dirfd is a new need. * src/common.h (open_searchdir_flags, get_directory_entries): (subfile_open, restore_parent_fd, tar_stat_close): New decls. (check_exclusion_tags): Adjust signature to match code change. * src/create.c (IMPOSTOR_ERRNO): New constant. (check_exclusion_tags): First arg is now a struct tar_stat_info const *, not an fd. All callers changed. (dump_regular_file, dump_file0): A zero fd represents an unused slot, so play it safe if the fd member is zero here. A negative fd represents the negation of an errno value, so play it safe and do not assign -1 to fd merely because an open fails. (open_failure_recover, get_directory_entries, restore_parent_fd): (subfile_open): New functions. These help to recover from file descriptor exhaustion. (dump_dir, dump_file0): Use them. (dump_file0): Use tar_stat_close instead of rolling our own close. * src/incremen.c (scan_directory): Use get_directory_entries, subfile_open, etc., to recover from file descriptor exhaustion. * src/names.c (add_hierarchy_to_namelist): Likewise. (collect_and_sort_names): A negative fd represents the negation of an errno value, so play it safe and do not assign -1 to fd. * src/tar.c (decode_options): Set open_searchdir_flags. Add O_CLOEXEC to all the open flags. (tar_stat_close): New function, which knows how to deal with new convention for directory streams and file descriptors. Diagnose 'close' failures. (tar_stat_destroy): Use it. * src/tar.h (struct tar_stat_info): New member dirstream. fd now has the negative of an errno value, not merely -1, if the file could not be opened, so that failures to reopen directories are better-diagnosed later. * tests/Makefile.am (TESTSUITE_AT): Add extrac11.at. * tests/testsuite.at: Likewise. * tests/extrac11.at: New file.
