Carefully crafted invalid headers can cause buffer overrun.
Invalid header fields go undiagnosed.
Some valid time strings are ignored.
* NEWS: Better support for full-resolution time stamps.
The -v option now prints time stamps only to 1-minute resolution.
* gnulib.modules: Add utimens.
* lib/.cvsignore: Add imaxtostr.c, inttostr.c, inttostr.h,
offtostr.c, umaxtostr.c, utimens.c, utimens.h. Remove paxconvert.c.
* lib/Makefile.tmpl (libtar_a_SOURCES): Remove paxconvert.c.

lib/obstack.c.
* src/buffer.c (set_start_time, compute_duration, start_time):
Use gettime rather than rolling our own code.

(newer_ctime_option): Remove.
(timespec_lt): New function.
(OLDER_STAT_TIME): Use it.

(tartime): Time arg is now struct timespec. New bool arg.
All callers changed.
(code_ns_fraction): New decl.
(sys_stat_nanoseconds): Remove decl.
(get_stat_atime, get_stat_ctime, get_stat_mtime): New functions.
(set_stat_atime, set_stat_ctime, set_stat_mtime): New functions.

Prototype.

(diff_file): Support higher-resolution time stamps.
* src/create.c: Include utimens.h rather than rolling our own.
(MAX_OCTAL_VAL): New macro.
(tar_copy_str, string_to_chars): Don't bother to zero-fill;
the destination is already zeroed.
(string_to_chars): First arg is char const *.
(start_private_header): Use MINOR_TO_CHARS, not MAJOR_TO_CHARS,
for minor device number.
(write_header_name, dump_hard_link, dump_file0):
Simplify test for old GNU format.
(start_header): Put in placeholders for uid, etc., even when
using extended headers, for benefit of older "tar" implementations.
Don't assume uintmax_t is wider than 32 bits.
Output extended header for mtime if needed.

Do not include <xstrtol.h>.
(strtoimax) [!HAVE_DECL_STRTOIMAX && !defined strtoimax]: New decl.
(strtoumax) [!HAVE_DECL_STRTOUMAX && !defined strtoumax]: New decl.
(BILLION, LOG10_BILLION): New constants.
(to_decimal): Remove; superseded by inttostr. All callers changed
to use umaxtostr.
(xheader_format_name): Don't assume pids and uintmax_t values
fit in 63 bytes (!) when printed.
(decode_record): Don't bother to check for ERANGE; an out of range
value must be treater than len_max anyway.
If the length is out of range, output it in the diagnostic.
(format_uintmax): Remove; all callers changed to use umaxtostr.
(xheader_print): Don't assume sizes can be printed in 99 bytes (!).
(out_of_range_header): New function.
(decode_time): Use it.
(code_time): Accept struct timespec, not time_t and unsigned long.
All callers changed. Size sbuf properly, and remove unnecessary check.
Don't assume time stamps can fit in 199 bytes.
Handle negative time stamps. Handle fractional time stamps
more consistently. Don't output unnecessary trailing zeros.
(decode_time): Yield struct timespec, not time_t and unsigned long.
All callers changed.
Handle negative time stamps. Truncate towards minus infinity
consistently. Improve overflow checks, and output a better
diagnostic on overflow.
(code_num): Don't assume uintmax_t can be printed in 99 bytes (!).
(decode_num): New function, for better diagnostics.
(atime_coder, atime_decoder, gid_decoder, ctime_coder):
(ctime_decoder, mtime_coder, mtime_decoder, size_decoder):
(uid_decoder, sparse_size_decoder, sparse_numblocks_decoder):
(sparse_offset_decoder, sparse_numbytes_decoder):
Use decode_num, etc., instead of xstrtoumax, etc.
* src/xheader.c (sparse_numblocks_decoder): Remove unchecked use
of `calloc'. Use xcalloc instead.
(decode_time, gid_decoder, size_decoder, uid_decoder):
(sparse_size_decoder, sparse_offset_decoder, sparse_numblocks_decoder):
Ensure that the result of calling xstrtoumax is no larger than
the maximum value for the target type. Upon any failure, exit with
a diagnostic.
(sparse_numblocks_decoder): Avoid buffer overrun/heap corruption:
use x2nrealloc, rather than `n *= 2' and xrealloc(p, n,....
(decode_time): Rewrite to accept time strings like
1119018481.
000000000. Before, such strings were always ignored.
(dump_file0): Check for is_avoided_name() first. Fixes bug reported by Martin Lohmeier
(AC_STRUCT_ST_BLKSIZE,AC_STRUCT_ST_BLOCKS): Removed. Handled by system.m4.
(read_name_from_file,update_argv): Automatically detect nul-terminated list files.
Bugfixes.
* src/misc.c (remove_any_file): Fix typo in previous change.
(remove_any_file): Fix typo in previous change.
Port to Solaris 10's treatment of unlinking directories.

* src/extract.c (we_are_root): Now static.
* src/misc.c: Include <unlinkdir.h>.
(remove_any_file): Use cannot_unlink_dir () rather than we_are_root.
Update FSF postal mail address.
(dump_regular_file): Correctly pad archive members that shrunk during archiving. Repored by Frank Heckenbach.
Update copyright.
Update copyright.
* src/incremen.c (hash_directory): Likewise.
* src/names.c (hash_string_hasher): Likewise.
* src/tar.c (parse_opt): Set it, and adjust to new modechange API.
Tell awk to read from /dev/null.
Adjust to new hash API.
Adjust to recent gnulib changes.
(parse_opt): Adjust to new modechange API.
(start_ueader): Adjust to new modechange API.
(initial_umask): New var.
Add dup-safer.c, fd-safer.c, unistd-safer.h.
* src/buffer.c (reading_from_pipe): Remove. All uses removed.
(short_read): Don't warn about short reads; they're normal.
* tests/shortrec.at: New file.
* tests/testsuite.at: Include it.
Use UTF-8 uniformly, rather than UTF-8 sometimes and Latin-1 sometimes.
Test splittind directory members between the archive volumes.
Minor fixes to text messages. Proposed by Benno Schulenberg.
(extract_file): Assign orig_file_name
to save_name uniformly over the program. This fixes matching
directory names at the start of an archive volume.
Minor fixes to text messages. Proposed by Benno Schulenberg.
Sort and simplify.
Update copyright date.
Rename config/ to build-aux/.
Spelling fixes.
(struct zip_magic): Use char arrays, not pointers.
The unsigned char * pointer ran afoul of pedantic C compilers, and
we didn't need pointers anyway. Put the size field before the
data to avoid unnecessary padding. All uses changed.
(magic) Make it const, since it doesn't change. All uses changed.
Use `head -n 1'. Provide missing argument to ${MT_STATUS}. Fixed typo in MT_OFFLINE assignment. Proposed by Jan Merka.
Use `head -n 1'. Provide missing argument to ${MT_STATUS}. Proposed by Jan Merka.
(sparse_scan_file): Bugfix. offset had incorrect type.
(read_header): Removed assignment to oldgnu_header.isextended. It was breaking append mode.
Added Tim Adye. Fixed UTF.
