chcon: exit immediately if SELinux is disabled

2009-10-06T08:10:51Z

This change happens to avoid an abort in chcon when SELinux is disabled while operating on a file with an "unlabeled" context from back in 2006. However, that same abort can still be triggered by the same file when running chcon with SELinux enabled. This bug in chcon will be fixed in a subsequent commit via a getfilecon wrapper. See http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/18378/focus=18384 for how to correct your disk attributes to avoid triggering this bug. * src/chcon.c (main): Exit immediately if SELinux is disabled. Reported in http://bugzilla.redhat.com/527142 by Yanko Kaneti. * src/runcon.c (main): Do not hardcode program name in error message. * THANKS: Update.

dircolors: highlight .cgm and .emf as images

2009-10-02T16:58:05Z

* src/dircolors.hin: Add .cgm, .emf. * THANKS: Update.

tail: avoid a race where we could miss new data with --pid

2009-10-02T13:00:06Z

* src/tail.c (tail_forever, tail_forever_inotify): Close a race in tail_forever_inotify where new data written after the file check by a now dead process, but before the pid check, is not output. We use the POSIX guarantee that read() and write() are serialized wrt each other even in separate processes, to assume full file consistency after exit() and so poll for new data _after_ the writer has exited. This also allows us to not redundantly _wait_ for new data if the process is dead. * tests/tail-2/pid: Remove the now partially invalid sub second sleep check as we now don't unconditionally wait, and replace it with a check for the redundant sleep. Also clarify some of the existing comments. * NEWS: Mention the fix.

ls: always print "?" for allocated size of a dereferenced dangling symlink

2009-09-30T14:42:35Z

Previously for `ls -Ls` (but not `ls -Lsl`), we referenced the st_blocks returned from the previous failed stat() call. This undefined value was seen to be 0 for dangling symlinks at least. * src/ls.c (print_file_name_and_frills, length_of_file_name_and_frills): Don't use st_blocks if the previous stat() failed * tests/ls/dangle: Add a test case * NEWS: Mention the fix, and roll up related items into a single entry.

stat: interpret "-" as standard input

2009-09-29T14:04:12Z

* src/stat.c (do_stat): Interpret a command line argument of "-" to mean "standard input", like many other tools do. (do_statfs): Fail upon any attempt to use "-". * NEWS (Changes in behavior): Mention it. * tests/misc/stat-hyphen: New test, to exercise the above. * tests/Makefile.am (TESTS): Add misc/stat-hyphen.

ls: don't use an undefined struct stat after failed stat/lstat

2009-09-29T12:12:30Z

* src/ls.c (format_inode): Access f->stat only if f->stat_ok is set. * NEWS (Bug fixes): Mention it. Improved-by: Pádraig Brady

ls: print "?", not "0" as inode of dereferenced dangling symlink

2009-09-29T09:42:45Z

ls prints inode numbers two ways: for long (-l) listings, and for short ones, e.g., ls -li and ls -i. The code to print long listings properly printed "?" when the inode was unknown, but the code for handling short listings would print 0 instead. Factor out the formatting code into a new function so ls prints the right string ("?") from both places: * NEWS (Bug fixes): Mention it. * src/ls.c (format_inode): New function. (print_long_format): Use it here. (print_file_name_and_frills): Use it here, too. * tests/ls/dangle: Exercise this fix. Reported by Yang Ren in http://bugzilla.redhat.com/525400

ls: with -LR, exit with status 2 upon detecting a cycle

2009-09-29T05:28:39Z

* src/ls.c (print_dir): Diagnosing the cycle is not enough. Also set exit status to 2. This is what Solaris' /bin/ls does, too. * tests/ls/infloop: Rework test: match both expected stdout and stderr. Require an exit status of 2 in this case. * doc/coreutils.texi (ls invocation): Mention that a loop provokes in an exit status of 2. * NEWS (Bug fixes): Mention it. Reported by Yang Ren in http://bugzilla.redhat.com/525402. * THANKS: Correct ordering of Yang Ren's names.

cp, mv: use linkat to guarantee semantics

2009-09-25T13:03:36Z

* src/copy.c (copy_internal): Use linkat, not link.

ln: add -L/-P options

2009-09-25T13:03:03Z

* src/ln.c (STAT_LIKE_LINK): Delete. (logical): New flag. (long_options): Add -L, -P. (usage): Mention them. (main): Choose between them. (do_link): Perform correct action. * tests/ln/misc: Move hard-to-sym portion of test... * tests/ln/hard-to-sym: ...into new test, and add more. * tests/Makefile.am (TESTS): Run new test. * NEWS: Document this. * doc/coreutils.texi (link invocation, ln invocation): Likewise. * bootstrap.conf (gnulib_modules): Add linkat.
