Problem reported by Jim Meyering (Bug#50611).
* src/digest.c (digest_check): When stripping trailing \r,
avoid subscript error before start of line.
|
|
* bootstrap.conf (gnulib_modules): Add rawmemchr.
* src/csplit.c: Include idx.h.
* src/csplit.c (record_line_starts):
* src/head.c (elide_tail_lines_pipe):
* src/shuf.c (next_line):
* src/split.c (lines_split):
* src/tail.c (pipe_lines):
* src/wc.c (wc_lines):
Prefer rawmemchr to memchr when rawmemchr is easy.
* src/csplit.c (load_buffer):
* src/head.c (struct linebuffer):
Make room for a 1-byte sentinel.
|
|
* src/split.c (lines_chunk_split): Don’t add to a null pointer.
It’s undefined behavior, and it’s unnecessarily confusing
regardless.
|
|
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.
|
|
* src/digest.c (usage): Indent multi-line descriptions for clarity.
|
|
This only practically matters on windows.
But given there are separate text handling options in cygwin,
keep the interface simple, and avoid exposing the
confusing binary/text difference here.
* doc/coreutils.texi (md5sum invocation): Mention that
--binary and --text are not supported by the cksum command.
* src/digest.c: Set flag to use binary mode by default.
(output_file): Don't distinguish text and binary modes with
' ' and '*', and just use ' ' always.
|
|
This format is a better default, since it results in simpler usage,
as you don't need to specify --tag on generation or -a on
checking invocations. Also it's a more general format supporting
mixed and length adjusted digests.
* doc/coreutils.texi (cksum invocation): Document a new --untagged
option, to use the older coreutils format.
(md5sum invocation): Mention that cksum doesn't support --tag.
* src/digest.c: Adjust cksum(1) to default to --tag,
and accept the new --untagged option.
* tests/misc/b2sum.sh: Adjust accordingly.
* tests/misc/cksum-a.sh: Likewise.
* tests/misc/cksum-c.sh: Likewise.
|
|
* src/cksum.h: Thread DELIM through the output functions.
* src/digest.c: Likewise.
* src/sum.c: Likewise.
* src/sum.h: Likewise.
* src/cksum.c: Likewise. Also adjust check to allow -z
with traditional output modes. Also ajust the global variable
name to avoid shadowing warnings.
* tests/misc/cksum-a.sh: Adjust accordingly.
|
|
This will be generally useful going forward, for sha3-256 etc.
* src/digest.c: Rename b2_length to digest_length, and
adjust/simplify the code to operate on this for both
b2sum and cksum -a blake2b.
|
|
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.
|
|
Any further variants will use the cksum -a table driven mechanism.
* src/digest.c: Remove BLAKE2 specific table driven code.
|
|
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 <tianjia.zhang@linux.alibaba.com>
|
|
* 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.
|
|
* cfg.mk: Adjust cksum.c to not require config.h
and support a main (for crctab) without calling bindtextdomain().
* po/POTFILES.in: Remove cksum_pclmul.c since it no longer
concerns itself with diagnostics.
* src/cksum.c: Refactor to just providing stream digest,
and digest printing functionality.
* src/cksum.h: Adjust to the new interface.
* src/cksum_pclmul.c: Remove diagnostics, and determine errors
internally.
* src/crctab.c: Separate from cksum.h since that's now included
multiple times.
* src/digest.c: Provide cksum(1) functionality if -DHASH_ALGO_CKSUM
* src/local.mk: Adjust to new crctab.c and HASH_ALGO_CKSUM define.
|
|
This should have been part of commit v8.32-113-gb73b9fcb1
* doc/coreutils.texi (cksum invocation): Add the --debug description.
* src/cksum.c (usage): Likewise.
(main): Also give explicit indication when using generic hardware.
|
|
* src/sum.c (bsd_sum_stream): Detect overflow when updating length.
(sysv_sum_stream): Likewise.
|
|
Since digest will be providing all digest functionality,
refactor sum.c into it.
* po/POTFILES.in: sum.c no longer has translatable strings so remove.
* src/digest.c: Call out to new stream interfaces in sum.c
* src/local.mk: Adjust sources for the sum binary.
* src/sum.c: Provide a stream interface for BSD and SYSV digests.
* src/sum.h: A new file to declare the exported functions in sum.c
|
|
* src/digest.c (digest_file): Add a LENGTH param,
to support cksum(1), and sum(1) which output the
length as part of their output.
|
|
md5sum.c will be the base for all digest functions,
so rename accordingly.
* src/md5sum.c: Rename to ...
* src/digest.c: ... renamed from md5sum.c
* scripts/git-hooks/commit-msg: Allow digest: commit prefix.
* po.POTFILES.in: Adjust to new name.
* src/local.mk: Likewise.
|
|
* doc/coreutils.texi (whoami invocation): Clarify it prints names,
not numeric IDs.
* man/whoami.x: Likewise.
* man/logname.x: Reference getlogin(3).
* src/logname.c: Clarify that it prints the login name,
rather than the name of the effective user ID.

Search for "direct color" at:
https://invisible-island.net/xterm/terminfo.html
* src/dircolors.hin: Add *direct* to match terminals that
support direct colors (24-bit color / TrueColor).
The trailing * will match entries like xterm-direct2.
Addresses https://bugs.gnu.org/39827
|
|
* src/sum.c (usage): Indicate that -r (BSD algorithm) is the default.
|
|
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.

Emil Lundberg <lundberg.emil@gmail.com> 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.
|
|
This patch modifies basenc to prefer signed integers to
unsigned, as signed are less error-prone.
This patch also updates Gnulib to to latest, which updates Gnulib’s
base32 and base64 modules to prefer signed to unsigned integers.
* src/basenc.c: Include idx.h.
(struct base2_decode_context): Use unsigned char, not unsigned
for an octet that must fit in an unsigned char.
(base_encode, struct base_decode_context)
(base64_decode_ctx_wrapper, prepare_inbuf, base64url_encode)
(base64url_decode_ctx_wrapper, base32_decode_ctx_wrapper)
(base32hex_encode, base32hex_decode_ctx_wrapper, base16_encode)
(base16_decode_ctx, z85_encode, Z85_HI_CTX_TO_32BIT_VAL)
(z85_decoding, z85_decode_ctx, base2msbf_encode)
(base2lsbf_encode, base2lsbf_decode_ctx, base2msbf_decode_ctx)
(wrap_write, do_encode, do_decode, main):
Prefer signed integers to unsigned.
(main): Treat extremely large wrap columns as if they were
infinite; that’s good enough. Since we’re now using xstrtoimax,
this allows ‘-w -0’ (same as ‘-w 0’).
* tests/misc/base64.pl (gen_tests): -w-0 is no longer an error.
|
|
Problem found with latest Gnulib and GCC 11.2.1.
* src/find-mount-point.h (find_mount_point):
Add _GL_ATTRIBUTE_MALLOC and _GL_ATTRIBUTE_DEALLOC_FREE.
|

This is so that commands like ‘fmt - -’ read from stdin
both times, even when it is a tty. Fix some other minor
issues that are related.
* src/blake2/b2sum.c (main):
* src/cksum.c (cksum):
* src/cut.c (cut_file):
* src/expand-common.c (next_file):
* src/fmt.c (fmt):
* src/fold.c (fold_file):
* src/md5sum.c (digest_file, digest_check):
* src/nl.c (nl_file):
* src/od.c (check_and_close):
* src/paste.c (paste_parallel, paste_serial):
* src/pr.c (close_file):
* src/sum.c (bsd_sum_file):
Use clearerr on stdin so that stdin can be read multiple times
even if it is a tty. Do not assume that ferror preserves errno as
POSIX does not guarantee this. Coalesce duplicate diagnostic
calls.
* src/blake2/b2sum.c (main):
* src/fmt.c (main, fmt):
Report read error, even if it's merely fclose failure.
* src/fmt.c: Include die.h.
(fmt): New arg FILE. Close input (reporting error) if not stdin.
All callers changed.
* src/ptx.c (swallow_file_in_memory): Clear stdin's EOF flag.
* src/sort.c (xfclose): Remove unnecessary feof call.

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.
|
|
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.
|
|
We must delay handling when \r is the last character
of the buffer being processed, as the next character
may or may not be \n.
* src/cat.c (pending_cr): A new global to record whether
the last character processed (in -E mode) is '\r'.
(cat): Honor pending_cr when processing the start of the buffer.
(main): Honor pending_cr if no more files to process.
* tests/misc/cat-E.sh: Add test cases.

Pacify GCC 11.1 -fanalyzer.
* src/uniq.c (check_file): Use simpler test to check whether this
is the first time through the loop. Although the old test was
correct, the new one is easier to understand and perhaps a tiny
bit more efficient.
|
|
Caught by GCC 11.1 -fanalyzer.
* src/numfmt.c (simple_strtod_int): Remove unnecessary test of
*endptr vs NULL. Presumably this was a typo and **endptr was
intended instead of *endptr, but an **endptr test is also
unnecessary since c_isdigit (0) returns false.
|
|
* src/ls.c: Fix ifdef indenting and long line.
|
|
In documentation and comments, don’t assume that secondary storage
devices are disk devices. Similarly, don’t assume that main memory
uses magnetic cores, which became obsolete in the 1970s.
* src/du.c (usage):
* src/ls.c (usage):
* src/shred.c (usage): Reword to avoid “disk” in usage messages.
|
|
* doc/coreutils.texi (ls invocation): Document implementation more
closely. Be more consistent about style. Omit some needless words.
* src/ls.c (usage): Don’t overdocument -f, as the details were wrong.
Omit -1 advice as it’s a bit obsolete now that we have --zero and
is a bit much for --usage output anyway.
|
|
* NEWS, doc/coreutils.texi (General output formatting):
* src/ls.c (usage):
Document this.
* src/ls.c (ZERO_OPTION): Rename from NULL_OPTION.
All uses changed.
(long_options): Rename --null to --zero.
(dired_dump_obstack, main, print_dir): Use '\n' instead of
eolbyte where eolbyte must equal '\n'.
(decode_switches): Decode --zero instead of --null.
--zero also implies -1, -N, --color=none, --show-control-chars.
Use easier-to-decipher code to set ‘format’ and ‘dired’.
Reject attempts to combine --dired and --zero.
* tests/local.mk: Adjust to test script renaming.
* tests/ls/zero-option.sh: Rename from tests/ls/null-option.sh,
and test --zero instead of --null.
|
|
* src/ls.c (enum time_type, enum sort_type, enum indicator_style)
(enum Dereference_symlink, ignore_mode):
Put ‘= 0’ after default values, since the code relies
on static storage defaulting to zero.
(enum sort_type): Reorder so that -1 can be used to represent unset.
(main): Test print_with_color after parse_ls_color may have reset it.
(decode_line_length): Return the line length instead of setting
static storage. All uses changed. Treat line lengths exceeding
PTRDIFF_MAX as infinite, to avoid pointer-subtraction glitches.
(stdout_isatty): New function, to avoid calling isatty twice.
(decode_switches): Calculate defaults more lazily, to avoid using
syscalls or getenv during startup unless the results are more
likely to be needed. Use -1 to indicate options that haven’t been
set on the command line yet. Move print_with_color test from
here to ‘main’. Suppress bogus GCC warning.
(getenv_quoting_style): Return the quoting style instead of
setting static storage.
(init_column_info): New arg MAX_COLS, to avoid recalculating it.
Caller changed.
|
|
* .gitignore: Cater for recently added poll module.
* src/stdbuf.c: Avoid false positive from sc_prohibit_readlink.
|
|
* NEWS, doc/coreutils.texi (General output formatting):
* src/ls.c (usage): Document this.
* src/ls.c (NULL_OPTION): New constant.
(long_options): Add --null.
(eolbyte): New static var.
(dired_dump_obstack, main, print_dir, print_current_files)
(print_many_per_line, print_horizontal, print_with_separator):
Output eolbyte instead of '\n'.
(decode_switches): Decode --null.
* tests/ls/null-option.sh: New file.
* tests/local.mk (all_tests): Add it.
|
|
* src/ls.c (dired_pos): Now off_t, not size_t, since it counts
output file offsets.
(dired_dump_obstack): This obstack's file offsets are now
off_t, not size_t.
(format_user_or_group, format_user_or_group_width):
ID arg is now uintmax_t, not unsigned long, since uid_t and
gid_t values might exceed ULONG_MAX.
(format_user_or_group_width): Use snprintf with NULL instead of
sprintf with a discarded buffer. This avoids a stack buffer,
and so should be safer.
|
|
Prefer functions or constants to macros where either will do.
That’s cleaner, and nowadays there’s no performance reason to
prefer macros. All uses changed.
* src/ls.c (INITIAL_TABLE_SIZE, MIN_COLUMN_WIDTH):
Now constants instead of macros.
(file_or_link_mode): New function, replacing the old macro
FILE_OR_LINK_MODE.
(dired_outbyte): New function, replacing the old macro DIRED_PUTCHAR.
(dired_outbuf): New function, replacing the old macro DIRED_FPUTS.
(dired_outstring): New function, replacing the old macro
DIRED_FPUTS_LITERAL.
(dired_indent): New function, replacing the old macro DIRED_INDENT.
(push_current_dired_pos): New function, replacing the old macro
PUSH_CURRENT_DIRED_POS.
(assert_matching_dev_ino): New function, replacing the old macro
ASSERT_MATCHING_DEV_INO.
(do_stat, do_lstat, stat_for_mode, stat_for_ino, fstat_for_ino)
(signal_init, signal_restore, cmp_ctime, cmp_mtime, cmp_atime)
(cmp_btime, cmp_size, cmp_name, cmp_extension)
(fileinfo_name_width, cmp_width, cmp_version):
No longer inline; compilers can deduce this well enough nowadays.
(main): Protect unused assert with ‘if (false)’ rather than
commenting it out, so that the compiler checks the code.
(print_dir): Output the space and newline in the same buffer
as the human-readable number they surround.
(dirfirst_check): New function, replacing the old macro
DIRFIRST_CHECK. Simplify by using subtraction.
(off_cmp): New function, replacing the old macro longdiff.
(print_long_format): No need to null-terminate the string now.
(format_user_or_group): Let printf count the bytes.
|
|
* src/ls.c (format_user_or_group_width, print_long_format):
Use return value from sprintf instead of calling strlen on
the resulting buffer, or inferring the length some other way.
|
|
|
|
* src/env.c (usage): Fix pluralization typo.
|
|
As originally reported in <https://bugzilla.redhat.com/1962515>,
df invoked without -a printed duplicated entries for NFS mounts
of bind mounts. This is a regression from commit v8.25-54-g1c17f61ef99,
which introduced the use of a hash table.
The proposed patch makes sure that the devlist entry seen the last time
is used for comparison when eliminating duplicated mount entries. This
way it worked before introducing the hash table.
Patch co-authored by Roberto Bergantinos.
* src/ls.c (struct devlist): Introduce the seen_last pointer.
(devlist_for_dev): Return the devlist entry seen the last time if found.
(filter_mount_list): Remember the devlist entry seen the last time for
each hashed item.
* NEWS: Mention the bug fix.

This fixes an unlikely stack out-of-bounds write reported by
Stepan Broz via Kamil Dudka (Bug#49209).
* bootstrap.conf (gnulib_modules): Replace select with poll.
* src/tail.c: Do not include <sys/select.h>.
[!_AIX]: Include poll.h.
(check_output_alive) [!_AIX]: Use poll instead of select.
(tail_forever_inotify): Likewise. Simplify logic, as there is no
need for a ‘while (len <= evbuf_off)’ loop.
|
|
|
|
* src/tail.c: remove redundant size checks before calls to
`xwrite_stdout`
|
|
* src/stat.c (default_format): Use decomposed decimal
representation (major,minor) in the default format.
This is least ambiguous for human interpretation,
and more consistent with ls for example.
Fixes https://bugs.gnu.org/48960
|
|
In preparation for changing the default device number
representation (to decomposed decimal), provide more
formatting options for device numbers.
These new (FreeBSD compat) formatting options are added:
%Hd major device number in decimal (st_dev)
%Ld minor device number in decimal (st_dev)
%Hr major device type in decimal (st_rdev)
%Lr minor device type in decimal (st_rdev)
%r (composed) device type in decimal (st_rdev)
%R (composed) device type in hex (st_rdev)
* doc/coreutils.texi (stat invocation): Document new formats.
* src/stat.c (print_it): Handle the new %H and %L modifiers.
(print_statfs): Adjust to passing the format as two chars
rather than an int. Using an int was introduced in commit db42ae78,
but using separate chars is cleaner and more extensible.
(print_stat): Likewise. Handle any modifiers and the new 'r' format.
(usage): Document the new formats.
* tests/misc/stat-fmt.sh: Add a test case for new modifiers.
