Update to 8.29 Upstream changes: 2017-12-27 Pádraig Brady version 8.29 * NEWS: Record release date. 2017-12-23 Pádraig Brady tests: avoid false failure on AIX 7.2 * tests/tail-2/pipe-f.sh: Close stdout in a subshell to ensure the current shell isn't impacted. Subsequent piped commands like `echo foo | blah` were seen to fail due to the previous closing of stdout. Reported by Assaf Gordon. doc: describe recent build checks for 32 bit time_t * README: Document the new handling of 32 bit time_t, with examples of how to build in 64 bit mode on AIX. Also mention that GNU make is desired on AIX due to its mishandling of the "[" target. Suggested by Assaf Gordon. 2017-12-21 Pádraig Brady tests: fix recent portability issues on solaris 10 * tests/misc/ptx.pl: Escape the '^' character which is otherwise considered as a line continuation character. * tests/misc/shred-remove.sh: sed doesn't support \n. maint: remove reference to excluded changelog item * build-aux/git-log-fix: Remove old entry. 2017-12-20 Pádraig Brady maint: add doc/coverage to .gitignore * .gitignore: Ignore the generated coverage report. doc: remove older ChangeLog items * Makefile.am: Update the oldest documented version to 8.20 which is now about 5 years old. 2017-12-18 Bernhard Voelker doc: mention which privileges are needed to chmod POSIX specification for chmod(1): https://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html * doc/coreutils.texi (chmod invocation): Add a sentence about who can change the file mode bits of a file - (almost) a copy from what POSIX requires. Fixes https://bugs.gnu.org/29207. 2017-12-16 Pádraig Brady tests: fix recent regressions with dash * tests/misc/timeout.sh: dash outputs the "Killed" message to stderr rather than the terminal. * tests/misc/usage_vs_getopt.sh: dash doesn't yet support the POSIX proposed $'...' shell quoting syntax. build: avoid a signed overflow warning in ptx * src/ptx.c (fix_output_parameters): GCC 6.3.1 with ./configure --enable-single-binary would give: error: assuming signed overflow does not occur when simplifying conditional to constant [-Werror=strict-overflow] if (file_index > 0) So change the type of file_index to signed (size_t). 2017-12-11 Bernhard Voelker maint: adjust for the renamed nstrfime gnulib module * bootstrap.conf: s/strftime/nstrfrime/. 2017-12-11 Pádraig Brady build: update gnulib submodule to latest * gnulib: Update with various build/test fixes. tests: fix false failure in new dd/nocache_eof test * test/dd/nocache_eof.sh: Also handle fadvise64_64 which is used on 32 bit x86. Note strace internally maps fadvise64_64 to {arm,xtensa}_fadvise64_64. tail: fix tailing non seekable files on certain systems * src/tail.c (tail_bytes): On systems were blksize_t is unsigned and the same size or wider than off_t (android for example), our initialized (off_t) -1 would be promoted to unsigned before comparison, and thus fail to follow the appropriate path. * tests/tail-2/tail-c.sh: Add a test case. * NEWS: Mention the fix. This issue was introduced in commit v8.23-47-g2662702 Reported at https://github.com/termux/termux-app/issues/233 build: avoid build failure without sys/mtio.h * m4/jm-macros.m4: Check for the header. * src/dd.c: Avoid the workaround where the header is not available (on non glibc systems). * src/shred.c: Likewise. doc: reorganize ls -k and --time-style help * src/ls.c (usage): Clarify -k only applies to -s usage and directory 'total' lines. Move the description of TIME_STYLE out of the option section as it was awkward to read and write there within 80 columns. 2017-12-10 Pádraig Brady doc: clarify numeric setuid handling in chmod man page * man/chmod.x: Update the information to state one can clear the setuid and setgid bits for directories numerically using an additional leading '0' or a leading '='. That has been supported since v8.15-64-g8931cdb. Fixes https://bugs.gnu.org/29390 doc: shred: change 'truncate' to the more descriptive 'deallocate' * doc/coreutils.texi (shred invocation): s/truncate/deallocate/. * src/shred.c (usage): Likewise. Fixes https://bugs.gnu.org/29317 doc: clarify that cp --force may recreate files * doc/coreutils.texi (cp invocation): The language used to describe recreating the file was a little confusing as it mentioned opening a removed file. Fixes https://bugs.gnu.org/29315 2017-12-04 Kamil Dudka doc: fix default QUOTING_STYLE for %N format of stat(1) * doc/coreutils.texi (stat invocation): The default value of QUOTING_STYLE for the %N format of 'stat --printf' is 'shell-escape-always'. Fixes https://bugs.gnu.org/29563 Reported by Christian Groessler at https://bugzilla.redhat.com/1520399#c3 2017-12-02 Jean Delvare tests: make ls/block-size more readable * tests/ls/block-size.sh: The output of the test was hard to read. Add comments saying what we are testing to make it easier to understand. 2017-11-29 Bernhard Voelker Pádraig Brady tests: verify usage vs. getopt Verify that all options mentioned in usage are actually recognized by the program. * tests/misc/usage_vs_getopt.sh: Add test. * tests/local.mk (all_tests): Reference it. 2017-11-29 Pádraig Brady readlink: remove superfluous comma from usage output * src/readlink.c (usage): Remove ',' after --quiet option. 2017-11-29 Bernhard Voelker all: use consistent diagnostics for unknown long options Previously, e.g. cksum failed to output the offending unknown long option: $ cksum --unknown-opt cksum: invalid option -- '-' Try 'cksum --help' for more information. i.e., it tried to diagnose '-' as short option. Instead, it should diagnose the unknown long option: $ cksum --unknown-opt cksum: unrecognized option '--unknown-opt' Try 'cksum --help' for more information. * src/cksum.c (long_options): Add struct with null entry only. (main): Use it in the getopt_long call. * src/dd.c: Likewise. * src/hostid.c: Likewise. * src/hostname.c: Likewise. * src/link.c: Likewise. * src/logname.c: Likewise. * src/nohup.c: Likewise. * src/sleep.c: Likewise. * src/tsort.c: Likewise. * src/unlink.c: Likewise. * src/uptime.c: Likewise. * src/users.c: Likewise. * src/whoami.c: Likewise. * src/yes.c: Likewise. * NEWS (Improvements): Mention the fix. 2017-11-29 Pádraig Brady test: fix issues with tests/cp/preserve-mode.sh * tests/cp/preserve-mode.sh: This was the only use of awk, which may not be available on the system resulting in an ineffective test. Also the permissions bits for directories were not being checked at all. build: update gnulib submodule to latest * gnulib: Update with various build/test fixes. 2017-11-28 Pádraig Brady build: update gnulib submodule to latest * gnulib: Update including various build fixes. 2017-11-27 Bernhard Voelker timeout: also support short -v option * src/timeout.c (main): Add short option character 'v' to getopt_long call. * tests/misc/timeout.sh: Run the test both for the long and the short option. 2017-11-25 Pádraig Brady dd: support iflag=direct with arbitrary sized files * src/dd.c (iread): Handle read error with a non-aligned file offset in the O_DIRECT case. This is not an issue on XFS at least, but on EXT4 the final read will return EINVAL rather than the expected 0 to indicate EOF. * tests/dd/direct.sh: Test the iflag=direct case also. * NEWS: Mention the improvement. 2017-11-24 Pádraig Brady timeout: add --verbose to diagnose timeouts This is useful as handling in shell is complicated with the varying exit status in the --kill-after case. * src/timeout.c (main): Handle '-v' and store COMMAND for the diagnostic. (cleanup): Diagnose the signal name before sending. (usage): Document -v, --verbose. * doc/coreutils.texi (timeout invocation): Likewise. * tests/misc/timeout.sh: Add a test case. * NEWS: Mention the new feature Fixes https://bugs.gnu.org/21760 2017-11-19 Pádraig Brady tail: seek to the end of block devices * src/tail.c (tail_bytes): Try lseek(..., SEEK_END) when we can't determine the file size. * tests/tail-2/end-of-device.sh: Add a new root only test. * tests/local.mk: Reference the new test. * NEWS: Mention the improvement. Paul Eggert suggested using lseek() (rather than ioctl(BLKGETSIZE64)). Fixes https://bugs.gnu.org/29259 2017-11-14 Bernhard Voelker maint: include the module year2038 from gnulib * bootstrap.conf (gnulib_modules): Add 'year2038' to ensure that time_t is 64-bit (and thus works after 2038). Suggested by Bruno Haible in https://lists.gnu.org/r/bug-gnulib/2017-11/msg00022.html 2017-11-14 Bernhard Voelker maint: update gnulib to latest * gnulib: Update - mainly for the recent year2038 changes. * tests/init.sh: Update from gnulib/tests/init.sh. 2017-11-09 Assaf Gordon doc: add github issue/pull-request templates These templates instruct contributors not to use github, and instead use the upstream GNU development resources. Discussed in http://lists.gnu.org/archive/html/coreutils/2017-11/msg00007.html . * .github/ISSUE_TEMPLATE.txt, .github/PULL_REQUEST_TEMPLATE.txt: New files. 2017-11-08 Jim Meyering maint: make hook script reject "/archive/html" in lists.gnu.org URLS * scripts/git-hooks/commit-msg: Require the abbreviated "/r/" form in any log message URL. maint: shorten https://lists.gnu.org/archive/html/... links Each /archive/html/ part can be replace with /r/. Run this to induce the change: git grep -l archive/html|xargs perl -pi -e 's,/archive/html/,/r/,g' * TODO: Perform that substitution. * bootstrap: Likewise. * src/sort.c (sequential_sort): Likewise. * src/tail.c (tail_file): Likewise. * tests/misc/sort-merge-fdlimit.sh: Likewise. * tests/misc/stty-row-col.sh: Likewise. * tests/misc/unexpand.pl: Likewise. * tests/rm/readdir-bug.sh: Likewise. * tests/tail-2/inotify-rotate.sh: Likewise. 2017-11-07 Thomas Deutschmann tests: avoid false failure with inaccessible mount points * tests/ls/readdir-mountpoint-inode.sh: Skip the test if any mount points are inaccessible by the current user. Fixes https://bugs.gnu.org/29167 Reported at: https://bugs.gentoo.org/353164 2017-11-06 Bernhard Voelker doc: fix "Up" field of realpath usage examples Older versions of 'makeinfo' choke on a missing reference: ./doc/coreutils.texi:14177: `Realpath usage examples' has no Up field\ (perhaps incorrect sectioning?). makeinfo: Removing output file `doc/coreutils.info' due to errors; \ use --force to preserve. * doc/coreutils.texi (realpath invocation): Add a menu referencing the usage examples - introduced in v8.27-91-g7449f0d. 2017-11-06 Pádraig Brady maint: ensure https:// URLs are used in --help and man pages * configure.ac(AC_INIT): Specify the URL explicitly, so we're not dependent on unreleased autoconf. 2017-10-31 Assaf Gordon stat: output default formats for --terse in usage Suggested by L A Walsh in https://bugs.gnu.org/28763 . * src/stat.c (fmt_terse_fs): Define format for --terse -f here. (fmt_terse_regular): Define format for --terse here. (fmt_terse_selinux): Likewise for when SELinux is enabled. (default_format): Use the above constants. (usage): Output the formats for the terse modes. 2017-10-30 Pádraig Brady df: fix hang with fifo argument * src/df.c (main): stat() before open(), and avoid the optional open when given a fifo argument. * tests/df/unreadable.sh: Add a test case. * NEWS: Mention the fix. Fixes https://bugs.gnu.org/29038 2017-10-28 Jim Meyering build: ls.c: apply _GL_ATTRIBUTE_PURE to more functions * src/ls.c (DEFINE_SORT_FUNCTIONS): Apply _GL_ATTRIBUTE_PURE to each strcmp-derived function definition, since GCC8 with -Wsuggest-attribute=pure now warns it is needed. 2017-10-26 Vincent Lefevre doc: reference statfs(2) in the stat(1) man page * man/stat.x (SEE ALSO): Mention statfs(2) in addition to stat(2). Note statfs() is generally used rather than statvfs(), so we'll defer that reference to the SEE ALSO section of statfs(2). Fixes https://bugs.gnu.org/28989 2017-10-25 Pádraig Brady tests: avoid false failure when O_DIRECT isn't supported * tests/dd/nocache_eof.sh: Only run the O_DIRECT tests when 512 byte alignment is supported. Otherwise with older XFS on systems with > 1MiB pages, or on file systems not supporting O_DIRECT, there would have been false failures. * tests/dd/direct.sh: Clarify the skip message. 2017-10-25 Pádraig Brady dd: fix nocache regions passed to posix_fadvise() Previously with oflag=direct the call to invalidate_cache() was not passed to the kernel, as it was less than a page size, and a subsequent call was not made to invalidate the pending space. Similarly with oflag=nocache the pending space at EOF was not invalidated. Even though these amount to only a single page in the page cache it can be significant. For example on XFS before kernel patch v4.9-rc1-4-g0ee7a3f, O_DIRECT files would have been read inefficiently if any pages were cached, even if they were already synced to storage. * src/dd.c (i_nocache_eof, o_nocache_eof): New bools used to control when we want invalidate_cache(,0) to clear to EOF. (cache_round): Use IO_BUFSIZE (currently 132KiB) to minimize calls to the relatively expensive advise function, rather than page_size. This also makes it clear that while the kernel function operates on pages, this size is chosen for performance reasons. (invalidate_cache): Refactor to share more code between input and output paths. Use i_nocache_eof and o_nocache_eof rather than proxying off max_records. Ensure we invalidate full pages when clearing to EOF as the kernel will ignore any non complete pages. Fix the offset used for the output path. (dd_copy): Invalidate the cache of the input after the offset is updated, for consistency and so we don't try to invalidate before the start of the file. When we read EOF on input, set flags so that we invalidate to EOF. (main): Invalidate to EOF in more cases, by depending on the i_nocache_eof and o_nocache_eof flags. * doc/coreutils.texi (dd invocation): Clarify the alignment and persisted caveats on the example applying "nocache" to part of a file. * tests/dd/nocache_eof.sh: A new test. * tests/local.mk: Reference the new test. * NEWS: Mention the bug fix. Issue reported by Eric Bergen. 2017-10-24 Michael Stone doc: mention QUOTING_STYLE env var in ls man page * src/ls.c (usage): Mention QUOTING_STYLE with the --quoting-style option, and indicate it has lower precedence than that option. 2017-10-24 Pádraig Brady maint: apply suggested cleanup to recent stty.c change This should have been part of commit v8.28-17-gf926f7c * src/stty.c (check_argument): Align line continuation chars, and ensure the function macro is immune to usage with if/else. Suggested by Jim Meyering and Paul Eggert. b2sum: fix crash with --check and truncated input * src/md5sum.c (split_3): Ensure we don't walk off the end of the string. * tests/misc/b2sum.sh: Add test cases. Fixes https://bugs.gnu.org/28860 2017-10-24 Pádraig Brady stty: fix processing of options when -F is specified This was a latent issue that became significant with the addition of the -F option in FILEUTILS-3_16n-56-ge46a424 * src/stty.c (apply_settings): Refactor argument checking to a function macro. Augment the argument check to ignore NULLed out arguments (already processed -F). * NEWS: Mention the fix. * tests/misc/stty-invalid.sh: Add a test case. Fixes https://bugs.gnu.org/28859 2017-10-24 Pádraig Brady timeout: fix a small race that would ignore command exit This fixes a regression from commit v8.26-39-g2f69dba * src/timeout.c (block_cleanup_and_chld): Rename from block_cleanup to indicate we also block SIGCHLD to avoid the race where SIGCHLD fires between waitpid() polling and sigsuspend() waiting for a signal. * NEWS: Mention the fix. 2017-10-24 Thomas Jarosch timeout: fix regression when invoked with blocked SIGCHLD We inherit the signal mask from our parent process, therefore ensure SIGCHLD is not blocked. If SIGCHLD is blocked, sigsuspend() won't be interrupted when the child process exits and we hang until the timeout (SIGALRM). This fixes a regression from commit v8.26-39-g2f69dba * src/timeout.c (install_sigchld): Ensure SIGCHLD is unblocked. * NEWS: Mention the issue. 2017-10-02 Pádraig Brady build: reinstate distribution of man pages man pages change little between systems, so falling back to distributed pages make sense when cross compiling or lacking perl. * man/local.mk: Add all man pages to EXTRA_DIST so that they're distributed in the generated tarball. Use the dummy-man page generator if cross compiling. Set TZ to avoid a distcheck failure where man pages used a diffent month than those rebuilt (with a .timestamp). * man/dummy-man: Only fall back to generating a stub if copying an existing man page fails. * man/help2man: Sync portable TZ=UTC0 specification from upstream help2man. * NEWS: Mention the build-related change. Fixes https://bugs.gnu.org/28574 2017-10-02 Pádraig Brady maint: remove a duplicate entry from THANKS * .mailmap: Prefer Colin Watson's last used email address. 2017-09-25 Paul Eggert copy: revert recent patch for vulnerable dirs I plan to propose a better patch to catch vulnerable parent directories. * NEWS, doc/coreutils.texi (Target directory): Document this. * src/cp.c, src/install.c, src/ln.c, src/mv.c: Do not include targetdir.h. (target_directory_operand): Remove test for vulnerable parents. * src/cp.c (stat_target_operand): Remove. All uses removed. * src/local.mk (noinst_HEADERS): Remove src/targetdir.h. (src_ginstall_SOURCES, src_cp_SOURCES, src_ln_SOURCES) (src_mv_SOURCES): Remove src/targetdir.c. * src/targetdir.c, src/targetdir.h: Remove. * tests/mv/vulnerable-target.sh: Remove. * tests/local.mk (all_root_tests): Remove it. 2017-09-24 Pádraig Brady tests: fix test hang on case insenitive file systems * tests/split/filter.sh: Due to an invalid 'FILE = zero.in' construct trying to initialize a FILE variable, it would instead try to run the FILE command which is present on macOS 10.13 with APFS. We also remove a redundant duplicate test clause introduced during a rebase, and simplify the piped timeout command, to avoid requiring a subshell and associated quoting. * THANKS.in: Add the reporter Jack Howarth. Fixes https://bugs.gnu.org/28506 2017-09-21 Pádraig Brady tests: avoid a false failure in expr test with UTF8 * tests/misc/expr.pl: Skip the quote varying tests in the multi-byte locales as these tests aren't that interesting in those locales. Also ERR_SUBST is already defined for some tests so awkward to redefine to munge UTF8 quotes to ASCII. 2017-09-20 Assaf Gordon expr: add detailed syntax error messages Show offending argument instead of a generic 'syntax error' message. Suggested by Bernhard Voelker in https://bugs.gnu.org/28461#13 . * src/expr.c (syntax_error): Remove. (required_more_args): New function. (eval7, main): Replace syntax_error call with detailed die message. * tests/misc/expr.pl: Add tests for new messages. 2017-09-20 Pádraig Brady maint: fix new syntax-check failures from HTTPS adjustments * cfg.mk [old_NEWS_hash]: update with `make update-NEWS-hash`. [sc_long_lines]: Avoid flagging (long) URLs in NEWS. * src/sort.c: Tweak to a shorter line. * src/tail.c: Likewise. Introduced in v8.28-4-gbe87d61 maint: fix new syntax check failures from copy restrictions * doc/coreutils.texi: Remove doubled word. * src/targetdir.c: Explicitly mark exported function. * tests/local.mk: This is not a root only test. * tests/mv/vulnerable-target.sh: Use returns_. Introduced in v8.28-3-g44ccd1c shred: reinstate --remove file name length obfuscation This was unintentionally removed in v8.27-60-g2ae1460 * src/shred.c (wipename): Interate through all name lengths. * tests/misc/shred-remove.sh: Add test cases. * NEWS: Mention the bug fix. Fixes https://bugs.gnu.org/28507 2017-09-19 Paul Eggert maint: copy bootstrap from Gnulib all: prefer HTTPS in URLs copy: check for vulnerable target dirs * NEWS, doc/coreutils.texi (Target directory): Document this. * src/cp.c, src/install.c, src/ln.c, src/mv.c: Include targetdir.h. (target_directory_operand): Use the new targetdir_operand_type function to check for vulnerable target directories. * src/cp.c (stat_target_operand): New function. (target_directory_operand, do_copy): Use it. * src/local.mk (noinst_HEADERS): Add src/targetdir.h. (src_ginstall_SOURCES, src_cp_SOURCES, src_ln_SOURCES) (src_mv_SOURCES): Add src/targetdir.c. * src/targetdir.c, src/targetdir.h: New files. * tests/mv/vulnerable-target.sh: New test. * tests/local.mk (all_root_tests): Add it. 2017-09-14 Bernhard Voelker ptx: avoid infloop due to zero-length matches with -S regex * src/ptx.c (find_occurs_in_text): Die with an appropriate error diagnostic when the given regular expression returns a match of length 0. * tests/misc/ptx.pl (S-infloop): Add a test. * NEWS (Bug fixes): Mention the fix. Fixes https://bugs.gnu.org/28417 which was detected using Symbolic Execution techniques developed in the course of the SYMBIOSYS research project at COMSYS, RWTH Aachen University. 2017-09-02 Pádraig Brady maint: post-release administrivia * NEWS: Add header line for next release. * .prev-version: Record previous version. * cfg.mk (old_NEWS_hash): Auto-update. version 8.28 * NEWS: Record release date. 2017-09-01 Pádraig Brady tests: fix false failure in recent ls --hyperlink test * tests/ls/hyperlink.sh: If the hostname or any part of the absolute path would be changed due to URL encoding, the test would fail. Therefore simplify to remove these components of the URL from consideration. maint: avoid a syntax-check failure * .gitignore: Remove lines indicated by sc_gitignore_redundant in a freshly checked out repo. 2017-08-31 Pádraig Brady tests: exclude the expensive gnulib fts-tests * gnulib: The only change in this gnulib update is the tagging of the fts-tests module as longrunning, which gnulib-tool currently implicitly excludes. This test was seen to take about 20s and 285MB. Reported by Assaf Gordon on space restricted VMs. tty: don't distinguish input errors * src/tty.c (main): Don't distinguish ENOTTY from other errors, because isatty() doesn't portably distinguish errors. Solaris returns ENOENT for all input errors for example. Musl also returns ENOENT, and ENODEV may be returned as disscussed at: http://openwall.com/lists/musl/2017/04/06/6 * tests/misc/tty.sh: Adjust accordingly. tests: avoid printf '0*d' construct unsupported by ash * tests/ln/sf-1.sh: Generate specific length with space padding which is supported. Reported by Assaf Gordon on Alpine Linux. 2017-08-31 Pádraig Brady tests: skip tests upon failure to set SELinux context On some setups the root:object_r:tmp_t context is invalid. This does indicate a limitation in the test framework, but for now we'll relax this to skipping the tests. The tests still run on a Fedora 25 system for example. * tests/cp/cp-a-selinux.sh: Upon chcon error, skip rather than ERROR. * tests/install/install-Z-selinux.sh: Likewise. * tests/misc/chcon.sh: Likewise. * tests/misc/runcon-no-reorder.sh: Likewise. * tests/misc/selinux.sh: Likewise. * tests/mkdir/restorecon.sh: Likewise. 2017-08-30 Kamil Dudka expr: fix a recently introduced memory leak * src/expr.c (eval6): Free memory allocated by mbs_logical_substr(). Introduced in v8.27-47-ga9f2be5. Detected by Coverity Analysis: Error: RESOURCE_LEAK: src/expr.c:851: leaked_storage: Variable "s" going out of scope leaks the storage it points to. 849| char *s = mbs_logical_substr (l->u.s, pos, len); 850| v = str_value (s); 851|-> } 852| freev (l); 853| freev (i1); 2017-08-30 Pádraig Brady build: fix build of renameat2 on Alpine Linux * gnulib: The only change included in this update it the added check for the presence of which is not present on Alpine Linux by default. tty: fix exit code with EINVAL * src/tty.c (main): All systems mention that isatty() man return EINVAL as well as (the POSIX compliant) ENOTTY. Also Centos 6 was seen to return EINVAL from ttyname(). * tests/misc/tty.sh: Fix a test issue where we assume standard input is always a valid tty. Reported by Assaf Gordon on OpenSolaris 5.10 and 5.11, and Centos 6.5 2017-08-30 Pádraig Brady runcon: revert "disable use of the TIOCSTI ioctl" This reverts commit v8.27-97-g8cb06d4 because the setsid() fallback was not implemented correctly and disabling the ioctl was not a complete solution to the security issue of the child being passed the tty of the parent. Given runcon is not really a sandbox command, the advice is to use `runcon ... setsid ...` to avoid this particular issue. 2017-08-30 Pádraig Brady stat: fix determination of max name length on BSD systems We only use one of statfs or statvfs for `stat -f` and on the BSDs we use statfs which doesn't have the f_namelen member. However on OpenBSD and later FreeBSD systems statfs does provide f_namemax, so use that. * NEWS: Mention the improvement for OpenBSD and FreeBSD. * m4/stat-prog.m4: Check for f_namemax in the statfs struct. * src/stat.c: Return '?' rather than '*' when we can't determine the max length of the file system. * tests/ln/sf-1.sh: This test was failing on all BSDs due to '*' being returned for the max length which caused the test to attempt to create 1Mi+1 names. The test now uses a short name when we can't determine the max name length to use. Reported by Assaf Gordon on various BSD based systems. 2017-08-29 Pádraig Brady stat,tail: support "AAFS" AppArmor file system * src/stat.c (human_fstype): This file system is used to manage AppArmor policy in the Linux kernel. all: update gnulib submodule to latest * bootstrap: Sync timestamp update. 2017-08-29 Pádraig Brady runcon: disable use of the TIOCSTI ioctl Similar to the issue with SELinux sandbox (CVE-2016-7545), children of runcon can inject arbitrary input to the terminal that would be run at the originating terminal privileges. The new libseccomp dependency is widely available and used on modern SELinux systems, but is not available by default on older systems like RHEL6 etc. * m4/jm-macros.m4: Check for libseccomp and warn if unavailable on selinux supporting systems. * src/local.mk: Link runcon with -lseccomp. * src/runcon.c (disable_tty_inject): A new function to disable use of the TIOCSTI using libseccomp, or with setsid() where libseccomp is unavailable. * tests/misc/runcon-no-inject.sh: A new test that uses python to make the TIOCSTI call, and ensure that doesn't succeed. * tests/local.mk: Reference the new test * NEWS: Mention the fix. Addresses http://bugs.gnu.org/24541 2017-08-29 Pádraig Brady ls: support --hyperlink to output file:// URIs Terminals such as iTerm2 and VTE based terminals (as of version 0.49.1), support hyperlinks when passed terminals codes as described at: https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda * src/ls.c (gobble_file): Allocate an absolute file name to output.

When the resource is used later on, then the wanted file system is mounted over that mount point on demand. 'df -l' triggered systemd to mount the file system because it called stat() on the mount point. Instead of single-casing "autofs" targets, we can avoid stat()ing all dummy file systems (which includes "autofs"), because those are skipped later on in get_dev() anyway. *src/df.c (filter_mount_list): Also skip dummy file systems unless the -a option or a specific target are given. * NEWS: Mention the fix.

Use xnmalloc to catch integer overflow. nohup: simplify by using fcntl * src/nohup.c: Do not include cloexec.h. (main): Use fcntl rather than dup + set_cloexec_flag. sort: use pthread_sigmask, not sigprocmask POSIX says sigprocmask has unspecified behavior in a multithreaded program like �<80><98>sort�<80><99>. * src/sort.c (pthread_sigmask) [GNULIB_defined_pthread_functions]: New macro, for use when �<80><98>sort�<80><99> is not multithreaded.

All callers changed. sort: minor cleanups * src/sort.c (move_fd): Rename from move_fd_or_die, since it no longer can die. sort: file descriptor discipline Use O_CLOEXEC when creating file descriptors, so that subsidiary processes do not inherit file descriptors that they do not need.

Addresses https://bugs.gnu.org/28054 seq: produce consistent error messages upon write error * src/seq.c (io_error): Use the same error message as would be generated at exit time when closing the stdout stream. The inconsistency was added with commit v8.25-26-gc92585b. This was noticed due to an inconsistency in the expected error message generated by seq on musl libc.

This is due to way that rule is careful to update the file, to avoid provoking a pointless rerunning of makeinfo. Note that this does not happen when one first runs "make distclean", as recommended in README-release. However, I sometimes run it as a more-rigorous "make check", and shouldn't have to manually run "make distclean" first, in that case. Before this change, one could reproduce the failure by running `touch -dyesterday doc/constants.texi && make distcheck`. It would fail with "makeinfo: could not open ../../doc/coreutils.info-t for writing: Permission denied" * Makefile.am (dist-hook): Touch the two generated files, so that they cannot be out of date wrt doc/coreutils.texi. 2017-06-17 Pádraig Brady maint: use C99 for loop initial declarations where possible This results in a net reduction of about 120 lines. tail: only use inotify with regular files * src/tail.c (any_non_regular): A new function to check passed files.
