version 9.0

* NEWS: Record release date.

stat,tail: add support for the secretmem file system

2021-09-16T14:21:05Z

* src/stat.c (human_fstype): Add case for the 'secretmem' file system type. * NEWS: Mention the Improvement.

digest: support windows format checksum files

2021-09-15T19:44:18Z

Support checksum files with CRLF line endings, which is a common gotcha for using --check on windows, or with checksum files generated on windows. Note we escape \r here to support the original coreutils format (with file name at EOL), and file names with literal \r characters as the last character of their name. * src/digest.c (filename_unescape): Convert \\r -> \r. (print_filename): Escape \r -> \\r. (output_file): Detect \r chars in file names. (digest_check): Ignore literal \r char at EOL. * tests/misc/md5sum.pl: Add a test case. * tests/misc/sha1sum.pl: Likewise. * NEWS: Mention the improvement.

cksum: support digest detection for tagged format

2021-09-15T19:44:18Z

Support `cksum --check FILE` without having to specify a digest algorithm, allowing for more generic file check instructions. This also supports mixed digest checksum files, supporting more robust multi digest checks. * src/digest.c (algorithm_from_tag): A new function to identify the digest algorithm from a tagged format line. (split3): Set the algorithm depending on tag, and update the expected digest length accordingly. * tests/misc/cksum-c.sh: Add a new test. * tests/local.mk: Reference the new test. * tests/misc/md5sum.pl: Adjust to more generic error. * tests/misc/sha1sum.pl: Likewise. * doc/coreutils.texi (md5sum invocation): Mention the new -c feature. * NEWS: Mention the new feature.

digest: add support for sm3

2021-09-15T19:44:18Z

Add message digest sm3, which uses the OSCCA SM3 secure hash (OSCCA GM/T 0004-2012 SM3) generic hash transformation. * bootstrap.conf: Add the sm3 module. * doc/coreutils.texi: Mention the cksum -a option. * src/digest.c: Provide support for --algorithm='sm3'. * tests/misc/sm3sum.pl: Add a new test (from Tianjia Zhang) * tests/local.mk: Reference the new test. * NEWS: Mention the new feature. Tested-by: Tianjia Zhang

cksum: add --algorithm option to select digest mode

2021-09-15T19:44:16Z

* src/digest.c: Organize HASH_ALGO_CKSUM to be table driven, and amalgamate all digest algorithms. (main): Parse all options if HASH_ALGO_CKSUM, and disallow --tag, --zero, and --check with the traditional bsd, sysv, and crc checksums for now. * src/local.mk: Reorganize to include all digest modules in cksum. * tests/misc/cksum-a.sh: Add a new test. * tests/misc/b2sum.sh: Update to default to checking with cksum, as b2sum's implementation diverges a bit from the others. * tests/local.mk: Reference the new test. * doc/coreutils.texi (cksum invocation): Adjust the summary to identify the new mode, and document the new --algorithm option. * man/cksum.x: Adjust description to be more general. * man/*sum.x: Add [See Also] section referencing cksum(1). * NEWS: Mention the new feature.

sum: always output a file name if one passed

2021-08-31T10:33:26Z

Adjust to output the file name if any name parameter is passed. This is consistent with sum -s, cksum, and sum implementations on other platforms. This should not cause significant compat issues, as multiple fields are already output, and so already need to be parsed. * src/sum.c (bsd_sum_file): Output the file name if any name parameter is passed. * tests/misc/sum.pl: Adjust accordingly. * doc/coreutils.texi (sum invocation): Likewise. * NEWS: Mention the change in behavior.

basenc: fix bug49741: using wrong decoding buffer length

2021-08-30T04:06:32Z

Emil Lundberg reports in https://bugs.gnu.org/49741 about a 'basenc --base64 -d' decoding bug. The input buffer length was not divisible by 3, resulting in decoding errors. * NEWS: Mention fix. * src/basenc.c (DEC_BLOCKSIZE): Change from 1024*5 to 4200 (35*3*5*8) which is divisible by 3,4,5,8 - satisfying both base32 and base64; Use compile-time verify() macro to enforce the above. * tests/misc/basenc.pl: Add test.

chmod: fix use of uninitialized var if -v

2021-08-16T04:32:09Z

Problem reported by Michael Debertol (Bug#50070). * NEWS: Mention the fix. * src/chmod.c (struct change_status): New struct, replacing the old enum Change_status. All uses changed. (describe_change): Distinguish between cases depending on whether 'stat' or its equivalent succeeded. Report a line of output even if 'stat' failed, as that matches the documentation. Rework to avoid casts. (process_file): Do not output nonsense modes computed from uninitialized storage, removing a couple of IF_LINTs. Simplify by defaulting to CH_NO_STAT.

df: fix bug with automounted

2021-08-11T18:22:40Z

If the command-line argument is automounted, df would use stat info that became wrong after the following open. * NEWS: Mention the fix (bug#50012). * src/df.c (automount_stat_err): New function. This fixes the hang on fifos in a better way, by using O_NONBLOCK. (main): Use it.
