A cross-partition move of a file in a sticky tmpdir and owned by
another user would evoke an invalid diagnostic after copying it:
mv: cannot remove `x': Operation not permitted
Either of the following (mv.c, remove.c) changes would fix the bug by
itself. I think it's slightly better to use both; the added cost is
minimal: mv: an extra lstat-per-mv-cmdline-arg-that-goes-cross-partition,
rm: an extra lstat-per-unlink-that-fails-w/EPERM.
* src/remove.c (remove_entry): Also lstat the file upon EPERM.
* src/mv.c (rm_option_init): Initialize root_dev_ino just as is done
in rm, so that a cross-partition invoked remove.c:rm call works the
same way as one invoked from the command-line use of "rm". That
setting of root_dev_ino makes rm() do the equivalent of an additional
lstat for each argument, which in turn gives rm enough information to
issue the right diagnostic.
* tests/mv/sticky-to-xpart (version): New file. Test for the above.
* tests/mv/Makefile.am (TESTS): Add sticky-to-xpart.
Arrange for "make check-root" to run the new root-only test.
* tests/Makefile.am (tb): New target, to run the new root-only test.
(all_t): Add tb.
* src/c99-to-c89.diff: Adjust offsets.
* tests/check.mk (TESTS_ENVIRONMENT): Add PACKAGE_VERSION here,
rather than in every Makefile.am that needs it.
* tests/rm/Makefile.am (TESTS_ENVIRONMENT): Remove PACKAGE_VERSION.
* tests/misc/Makefile.am (TESTS_ENVIRONMENT): Likewise.
* src/copy.c (copy_internal): When same-file detection requires
'stat'ing the destination file, also 'lstat' it and ensure that
it wasn't the destination of a preceding copy operation.
This bug was introduced on 2007-06-18.
* tests/cp/abuse: New test for the above.
* tests/cp/Makefile.am (TESTS): Add abuse.
* bootstrap.conf (gnulib_modules): Remove file-set, now that
it's in gnulib, and the canonicalize module requires it there.
* gl/lib/file-set.c, gl/lib/file-set.h, gl/modules/hash-triple: Remove.
* gl/lib/hash-triple.c, gl/lib/hash-triple.h, gl/modules/file-set: Remove.
* tests/misc/readlink-fp-loop: New file. Test for the readlink bug
fixed through today's change to Gnulib's canonicalize module.
* tests/misc/Makefile.am (TESTS): Add readlink-fp-loop.
Bug report and a test case from mpb.mail@gmail.com.
* doc/coreutils.texi (date invocation):
`man date` gives all options for the date command except
the description of the date input formats. Therefore it
should be easy to browse to this info using `info date`.

* gl/lib/hash-triple.c (triple_hash): Use XOR (^), not OR (|), to
combine the bits from hashing the name and those of the inode number.
Add a few comments and remove out-of-context ones.
On some systems (those with openat et al), when rm would fail to
remove a symlink, it would fail with the misleading diagnostic,
"Too many levels of symbolic links".
* NEWS: Mention the bug fix.
* src/remove.c (is_nondir_lstat): New function.
(remove_entry): Use it to catch failed-to-remove symlink (and any
other non-dir) here so that we don't fall through and try to treat
it as directory, which -- with a symlink -- would provoke the bogus
ELOOP failure.
* tests/rm/fail-eacces: Add a test for the above.
* src/c99-to-c89.diff: Adjust offsets.
Don't perform a "."-relative lstat, when the file in question
may well not be in ".". Although this is a bug, a few attempts
to exercise it on a linux-2.6.22 system failed. You probably need
a pre-openat system to trigger the failure. The consequence of this
bug would be a lower-quality diagnostic upon failed dir removal.
* src/remove.c (is_dir_lstat): Add a parameter, fd_cwd.
Use it instead of hard-coding AT_FDCWD.
(remove_entry): Call is_dir_lstat with fd_cwd.
