2014-05-29df: use the last device name provided by the systemPádraig Brady
The device name reported for a particular mount entry may no longer be valid if the mount point was subsequently mounted on a different device. Therefore honor the order of the mount list returned by the system and use the last reported device name. * src/df.c (filter_mount_list): When discarding the current mount entry, ensure that a new device name is not also discarded. * tests/df/skip-duplicates.sh: Add a test case. Also fix a false failure in the edge case of a system with only a single file system. * NEWS: Mention the fix.
2014-05-21tests: use chroot --user rather than internal setuidgid toolPádraig Brady
* init.cfg (require_root_): Adjust to use chroot, and make `require_built_ chroot` implicit when chroot used in the test. * po/POTFILES.in: Remove reference to setuidgid tool. * src/.gitignore: Likewise. * src/local.mk: Likewise. * src/setuidgid.c: Remove. * tests/cp/preserve-gid.sh: s/setuidgid/chroot --user/. * tests/cp/special-bits.sh: Likewise. * tests/id/setgid.sh: Likewise. * tests/misc/truncate-owned-by-other.sh * tests/mv/sticky-to-xpart.sh: Likewise. * tests/rm/fail-2eperm.sh: Likewise. * tests/rm/no-give-up.sh: Likewise. * tests/touch/now-owned-by-other.sh: Likewise. * tests/misc/chroot-fail.sh: Skip if chroot not built.
2014-05-21chroot: make changing root check more robustPádraig Brady
* src/chroot.c (is_root): A new helper function to determine if the passed argument is the root directory based on inode comparison. (main): Use the new helper rather than comparing strings. * tests/misc/chroot-fail.sh: Add cases for alternative root paths.
2014-05-21chroot: with --userspec clear root's supplemental groupsPádraig Brady
It's dangerous and confusing to leave root's supplemental groups in place when specifying other users with --userspec. In the edge case that that is desired one can explicitly specify --groups. Also we implicitly set the system defined supplemental groups for a user. The existing mechanism where supplemental groups needed to be explicitly specified is confusing and not general when the lookup needs to be done within the chroot. Also we extend the --groups syntax slightly to allow clearing the set of supplementary groups using --groups=''. * src/chroot.c (setgroups): On systems without supplemental groups, clearing then is a noop and so should return success. (main): Lookup the primary GID with getpwuid() when just a numeric uid is specified, and also infer the USERNAME from this call, needed when we're later looking up the supplemental groups for a user. Support clearing supplemental groups, either implicitly for unknown users, or explicitly when --groups='' is specified. * tests/misc/chroot-credentials.sh: Various new test cases * doc/coreutils.texi (chroot invocation): Adjust for the new behavior. * NEWS: Mention the change in behavior.
2014-05-16chroot: don't chdir() if not changing rootPádraig Brady
This allows chroot to be used as a light weight tool to change user identification for a command, while not changing the current working directory. It also makes `chroot / true` consistently succeed on all platforms for non root users. * src/chroot.c (main): If the same root is specified. i.e. '/' then don't change the current working directory, and avoid the overhead of the other redundant calls. * tests/misc/chroot-fail.sh: Remove failure guard previously needed on some systems. Also add an explicit case to ensure we don't change directory. * NEWS: Mention the change in behavior.
2014-05-13df: ignore non file system entries in /proc/mountsPádraig Brady
Linux with network namespaces contains entries in /proc/mounts like: proc net:[4026532464] proc rw,nosuid,nodev,noexec,relatime 0 0 resulting in a failure to stat 'net:[...]', inducing a warning and an exit with failure status. * src/df.c (get_dev): Ignore all relative mount points. * tests/df/skip-duplicates.sh: Add an entry to test relative dirs.
2014-05-13df: fix handling of symlinks in mount listPádraig Brady
The symlink handling in commit v8.21-172-g33660b4 was incomplete in the case where there were symlinks in the mount list itself. For example, in the case where /dev/mapper/fedora-home was in the mount list and that in turn was a symlink to /dev/dm-2, we have: before> df --out=source /dev/mapper/fedora-home devtmpfs after > df --out=source /dev/mapper/fedora-home /dev/mapper/fedora-home * src/df.c (get_disk): Compare canonicalized device names from the mount list. Note we still display the non canonicalized name, even if longer, as we assume that is the most representative. * tests/df/df-symlink.sh: This could theoretically fail on some systems depending on the content of the mount list, but adjust to fail on any system where symlinks are present in the mount list for the current dir.
2014-05-13df: also deduplicate virtual file systemsPádraig Brady
* src/df.c (filter_mountlist): Remove the constraint that a '/' needs to be in the device name for a mount entry to be considered for deduplication. Virtual file systems also have storage associated with them (like tmpfs for example), and thus need to be deduplicated since they will be shown in the default df output and subject to --total processing also. * test/df/skip-duplicates.sh: Add a test to ensure we deduplicate all entries, even for virtual file systems. Also avoid possible length operations on many remote file systems in the initial check of df operation. Also avoid the assumption that "/root" is on the same file system as "/". * NEWS: Mention the change in behavior.
2014-05-13tests: fix spurious failure with leading spaces in file namesPádraig Brady
* tests/ls/stat-vs-dirent.sh: This test lists all parent directories, and would spuriously fail if any of those had a file name with a leading space as the first entry. There is only ever a single space between the right aligned inode number and the file name, so process accordingly.
2014-05-10shred: don't infloop upon negative sizeJim Meyering
* src/shred.c (main): With the preceding change, shred -s-2 FILE would write 64KB blocks forever -- or until disk full. This change makes shred reject a negative size. * tests/misc/shred-negative.sh: New file. * tests/local.mk (all_tests): Add it.
2014-05-07tests: improve new ascii test of ddBernhard Voelker
* tests/dd/ascii.sh: Avoid unnecessary subshells. Catch dd's exit code. Remove testing artifact. In the case of a comparison failure, show the differences in octal format in addition to "binary files differ". Simplify the creation of the 'in' file.
2014-05-06dd: fix conv=ascii, conv=ebcdic, conv=ibm to match POSIXPaul Eggert
Problem reported by Don Baggett in <http:/bugs.gnu.org/17422>. * NEWS: * doc/coreutils.texi (dd invocation): Document this. * src/dd.c (conversions): conv=ascii implies conv=unblock. conv=ebcdic and conv=ibm imply conv=block. (ascii_to_ebcdic, ebcdic_to_ascii): Correct to match POSIX 1003.1-2013. * tests/dd/ascii.sh: New file. * tests/local.mk (all_tests): Add it.
2014-05-07tests: improve diagnostics when asserting empty filesPádraig Brady
* tests/chmod/c-option.sh: Use `compare /dev/null ... || fail=1` rather than `test -s ... && fail=1`, so that the file contents are output, thus improving diagnostics for failing tests. * tests/cp/acl.sh: Likewise. * tests/cp/cp-a-selinux.sh: Likewise. * tests/cp/cp-mv-enotsup-xattr.sh: Likewise. * tests/cp/reflink-perm.sh: Likewise. * tests/dd/misc.sh: Likewise. * tests/misc/env-null.sh: Likewise. * tests/misc/env.sh: Likewise. * tests/misc/nice.sh: Likewise. * tests/misc/nohup.sh: Likewise. * tests/misc/printenv.sh: Likewise. * tests/misc/xattr.sh: Likewise. * tests/mv/update.sh: Likewise. * tests/rm/deep-2.sh: Likewise. * tests/rm/read-only.sh: Likewise. * tests/split/r-chunk.sh: Likewise. * tests/tail-2/follow-stdin.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/touch/no-dereference.sh: Likewise. * cfg.mk (sc_prohibit_test_empty:): New syntax-check. * tests/cp/proc-zero-len.sh: Adjust to avoid false syntax-check failure. * tests/cp/proc-zero-len.sh: Likewise. * tests/mv/part-symlink.sh: Likewise. * tests/tail-2/infloop-1.sh: Likewise.
2014-05-06mv,cp: preserve symlink xattrs when copying across file systemsPádraig Brady
* src/copy.c (copy_internal): Include the copy_attr() call for symlinks. This should not dereference symlinks, since llistxattr() is used in attr_copy_file() in libattr, and so should copy all but the filtered extended attributes. Note we don't just move the copy_attr() call before the set_owner() call, as that would break capabilities for non symlinks. * tests/cp/cp-mv-enotsup-xattr.sh: Add a test case. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/16131
2014-05-05tests: initial SMACK testsJarkko Sakkinen
* init.cfg (require_smack_): New function. * local.mk: Referenced new tests. * tests/id/smack.sh: SMACK tests (new file). * tests/mkdir/smack-no-root.sh: SMACK tests (new file). * tests/mkdir/smack-root.sh: SMACK tests (new file).
2014-05-02numfmt: support zero padding using --format="%010f"Pádraig Brady
* src/numfmt.c (setup_padding_buffer): Simplify the code by not explicitly dealing with heap exhaustion. (parse_format_string): Likewise. Handle multiple grouping modifiers as does the standard printf. Handle the new leading zero --format modifier. (double_to_human): Use more defensive coding against overwriting stack buffers. Honor the leading zeros width. (usage): Mention the leading zero --format modifier. (main): Allow --padding in combo with a --format (width), as the number of leading zeros are useful independent of the main field width. * doc/coreutils.texi (numfmt invocation): Likewise. * tests/misc/numfmt.pl: Add new test cases. * NEWS: Mention the improvement.
2014-04-29ptx: fix whitespace trimming with multiple filesPádraig Brady
This issue was identified by running the test suite with http://code.google.com/p/address-sanitizer/ which is included in GCC 4.8 and enabled with -fsanitize=address This was checked on Fedora 20 with GCC 4.8 as follows: $ yum install libasan # http://bugzilla.redhat.com/991003 $ rm -f src/ptx.o $ make check AM_CFLAGS='-fsanitize=address' SUBDIRS=.

"The underlying problem is that swallow_file_in_memory() is setting the contents of the global text_buffer for the first file, then updating it (clobbering old value) for the second file. Yet, some pointers to the initial buffer have been squirreled away and later, one of them (keyafter) is presumed to point into the new "text_buffer", which it does not. The subsequent SKIP_WHITE_BACKWARDS use backs up "cursor" and goes out of bounds." * src/ptx.c (text_buffers): Maintain references for the limits of each buffer corresponding to each file, rather than just the last processed. (struct OCCURS): Add a member to map back to the corresponding file. Note normally this could be computed from the "reference" member rather than needing the extra storage, however this is not possible when in --references mode. (find_occurs_in_text): Reference the array rather than a single entry. (define_all_fields): Likewise. Also avoid computing the file index since this is now stored directly. (main): Update text_buffers[] array rather than a single text_buffer. * tests/misc/ptx-overrun.sh: Even though this issue is already triggered with AddressSanitizer, add a new case to demonstrate the whitespace trimming issue, and to trigger without AddressSanitizer. Fixes https://bugs.gnu.org/16171
2014-04-18tests: make ls tests independent of COLORTERM envPádraig Brady
Since the recent commit v8.22-68-g08783f1, ls coloring is now dependent on the COLORTERM environment variable. * tests/envvar-check: Unset COLORTERM from test environment. * tests/ls/color-dtype-dir.sh: Ensure coloring is used. * tests/misc/ls-misc.pl: Likewise. Prompted by the continuous integration build failure at: http://hydra.nixos.org/build/10397646
2014-04-17ls: don't output colors with unknown TERM env variableGuilherme de Almeida Suckevicz
--colors controls whether to output colors depending on whether we're connected to a terminal or not, while this change gives control over which terminals we output colors to. * NEWS: Mention the change in behavior. * src/ls.c (known_term_type): A new function to search the static list from dircolors.h (parse_ls_colors): Honor the TERM when both LS_COLORS and COLORTERM are non empty. * tests/ls/color-term.sh: A new test. * tests/local.mk: Reference the new test. Fixes http://bugs.gnu.org/15992
2014-04-11tests: fix false dd conv=sparse failure on newer XFSPádraig Brady
* tests/dd/sparse.sh: When testing that a hole is created, use an existing sparse destination file, so that we're not write extending the file size, and thus avoiding speculative preallocation which can result in smaller holes than requested. Workaround suggested by Brian Foster
2014-04-05maint: various cleanupsPádraig Brady
* tests/misc/numfmt.pl: Fix comment misspelling. * src/cut.c: Likewise. * src/tsort.c (detect_loop): Replace an fprintf() with error().
2014-04-05shred: overwrite inode storage used by some file systemsPádraig Brady
* doc/coreutils.texi (shred invocation): Mention some reasons why clearing slack space might be useful. * src/shred.c (do_wipefd): Add initial writes for each pass for small regular files in case the storage for those is in the inode, and thus a larger write up to a block size would bypass that. Move the direct I/O control to... (dopass): ... here so we can avoid enabling it for these small initial writes. It's better to retry direct I/O for each pass anyway to handle the case where direct I/O is disabled for only the last portion of a file when the size is not a multiple of the block size. Note we don't avoid the sync for the initial write as it will be small but more importantly could be on a different part of the disk and so worth doing independently to ensure the write is not discarded. * tests/misc/shred-exact.sh: Check some more direct I/O cases. * NEWS: Mention the improvements. The inode storage issue was mentioned by Paul Eggert.
2014-04-04shred: avoid a data pass on empty filesPádraig Brady
* src/shred.c (do_wipefd): Don't increase the size written for an empty file up to a full block. Also increase the size to OFF_T_MAX in the edge case where we do overflow. * NEWS: Mention the shred improvements from recent changes. * tests/misc/shred-passes.sh: Adjust as we no longer write a BLKSIZE of data for empty files.
2014-03-31head: fix bug with head -c-N when stdin is not at startPaul Eggert
* src/head.c (elide_tail_bytes_file): Fix typo in lseek invocation. * tests/misc/head-c.sh: Add test for this bug. * NEWS: Document this.
2014-03-26mv: fix issues with previous prompt adjustmentsPádraig Brady
* src/copy.c (overwrite_ok): Fix the gettext calls so that the second string is tagged for translation. Display the correct "replace ..." prompt when in move_mode. * tests/mv/i-3.sh: Display the output on failure to ease debugging.
2014-03-26ptx: avoid --format long option falling through into --helpBernhard Voelker
* src/ptx.c (main): Add a 'break' after the --format handling case. Otherwise it would fall through into the usage case. * tests/misc/ptx.pl: Add test cases for --format=tex and --format=roff. * NEWS (Bug fixes): Mention the fix. Bug introduced in 1999-04-04 commit, SH-UTILS-1_16f-269-gd815c15. Spotted by coverity (MISSING_BREAK).
2014-03-24cp: improve quality of overwrite promptPaul Eggert
* src/copy.c (overwrite_prompt): New arg X. All callers changed. Use X to improve the quality of the prompt (Bug#17087). * tests/mv/i-2.sh, tests/mv/i-3.sh: Change test to match new prompt.
2014-03-19chmod: fix erroneous warnings with -R --changesDylan Simon
For files with "special" bits set, we would stat the relative file name in the wrong directory, giving an erroneous ENOENT diagnostic. This issue was introduced with commit v5.92-653-gc1994c1 which changed fts to not change directory on traversal. * src/chmod.c (mode_changed): Use fts->fts_cwd_fd with fstatat rather than stat. All callers changed. * tests/chmod/c-option.sh: Add a test case. * NEWS: Mention the fix. Fixes http://bugs.gnu.org/17035
2014-03-13ln: with -sr, don't segfault for a TARGET of ''Jim Meyering
Prior to this change, "ln -sr '' F" would segfault, attempting to read path2[1] in relpath.c's path_common_prefix function. This problem arises whenever canonicalize_filename_mode returns NULL. * src/ln.c (convert_abs_rel): Call relpath only when both canonicalize_filename_mode calls return non-NULL. * tests/ln/relative.sh: Add a test to trigger this failure. * THANKS.in: List reporter's name/address. * NEWS (Bug fixes): Mention it. Reported by Erik Bernstein in 739752@bugs.debian.org. Fixes http://bugs.gnu.org/17010.
2014-03-13chroot: improve --userspec and --groups look-upPádraig Brady
- Support arbitrary numbers in --groups, consistent with what is already done for --userspec - Avoid look-ups entirely for --groups items with a leading '+' - Support names that are actually numbers in --groups - Ignore an empty --groups="" option for consistency with --userspec - Look up both inside and outside the chroot with inside taking precedence. The look-up outside may load required libraries to complete the look-up inside the chroot. This can happen for example with a 32 bit chroot on a 64 bit system, where the 32 bit NSS plugins within the chroot fail to load. * src/chroot.c (parse_additional_groups): A new function refactored from set_addition_groups(), to just do the parsing. The actual setgroups() call is separated out for calling from the chroot later. (main): Call parse_user_spec() and parse_additional_groups() both outside and inside the chroot for the reasons outlined above. * tests/misc/chroot-credentials.sh: Ensure arbitrary numeric IDs can be specified without causing look-up errors. * NEWS: Mention the improvements. * THANKS.in: Add Norihiro Kamae who initially reported the issue with a proposed patch. Also thanks to Dmitry V. Levin for his diagnosis and sample patch.
2014-03-05tests: avoid the :> construct which can hide errorsPádraig Brady
On most shells `:>file || framework_failure_` will not evaluate the framework_failure_ even if there was an error writing the file. shells which do evaluate the failure are ksh 93u+ and bash 4.2, while shells wich don't include bash 4.3, solaris, freebsd, dash. Furthermore this construct is problematic on Solaris 10 sh, which will try to optimize away a `:' command in a loop after the first iteration, even if it is redirected. * tests/cp/link-deref.sh: Remove the leading colon on redirections. * tests/cp/reflink-perm.sh: Likewise. * tests/id/zero.sh: Likewise. * tests/install/install-C.sh: Likewise. * tests/misc/env.sh: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/runcon-no-reorder.sh: Likewise. * tests/mv/partition-perm.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/tail-2/inotify-rotate.sh: Likewise. * tests/tail-2/retry.sh: Likewise. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/touch/read-only.sh: Likewise. + cfg.mk (sc_prohibit_colon_redirection): A new syntax check to avoid further instances of this creeping in.
2014-03-05tests: fix false failure in nohup.sh in non tty buildsPádraig Brady
* tests/misc/nohup.sh: When running tests without a controlling tty, an exec failure is triggered in a subshell, which causes POSIX shells to immediately exit the subshell. This was brought to notice by the newly conforming bash 4.3. Fixes http:/bugs.gnu.org/16940
2014-02-27date: fix crash or infinite loop when parsing a malformed TZ=""Pádraig Brady
* NEWS: Mention the fix. * gnulib: Update to incorporate the fix. This is the only change in this gnulib update. * tests/misc/date.pl: Add a test for this case. Fixes http://bugs.gnu.org/16872
2014-02-23shuf: with -r, don't dump core if the input is emptyPaul Eggert
Problem reported by valiant xiao in <http://bugs.gnu.org/16855>. * NEWS: Document this. * src/shuf.c (main): With -r, report an error if the input is empty. * tests/misc/shuf.sh: Test for the bug.
2014-02-10cp: with --link always use linkat() if availablePádraig Brady
* src/copy.c (copy_reg): If linkat() is available it doesn't matter about the gnulib emulation provided, and thus the LINK_FOLLOWS_SYMLINKS should not have significance here. This was noticed on FreeBSD and the consequence is that cp --link will create hardlinks to symlinks there, rather than emulating with symlinks to symlinks. * tests/cp/link-deref.sh: Adjust the checks to cater for all cases where hardlinks to symlinks are supported.
2014-02-09head,tail: consistently diagnose write errorsPádraig Brady
If we can't output more data, we should immediately diagnose the issue and exit rather than consuming all of input (in some cases). * src/tail.c (xwrite_stdout): Also diagnose the case where only some data is written. Also clearerr() to avoid the redundant less specific error from atexit (close_stdout); * src/head.c (xwrite_stdout): Copy this new function from tail, and use it to write all output. * tests/misc/head-write-error.sh: A new test to ensure we exit immediately on write error. * tests/local.mk: Reference the new test.
2014-02-09head: fix --lines=-0 outputting nothing if no newline at EOFАлексей Шилин
* src/head.c (elide_tail_lines_pipe): Just output all input in this case to avoid the issue and also avoid redundant '\n' processing. (elide_tail_lines_seekable): Likewise. * tests/misc/head-elide-tail.pl: Add tests for no '\n' at EOF. * NEWS: Mention the fix. Fixes http://bugs.gnu.org/16329
2014-02-09od: add an --endian option to control byte swappingNiels Möller
* src/od.c (main): Handle the new --endian option, taking "little" and "big" as parameters. (usage): Describe the new option. (PRINT_FIELDS): Adjust to swap bytes if required. * tests/misc/od-endian.sh: A new test to verify the byte swapping operations for hex (ints) and floats for all sizes between 1 and 16 inclusive. * test/local.mk: Reference the new test. * doc/coreutils.texi (od invocation): Describe the new option. * NEWS: Mention the new feature.
2014-01-24tests: skip chown/separator with conflicting group IDsAssaf Gordon
* tests/chown/separator.sh: skip test if the user's group has multiple entries. Fixes http://bugs.gnu.org/16532
2014-01-17ln: fix replacing symbolic links whose targets can't existPádraig Brady
* src/ln.c (errno_nonexisting): A new function to determine if the errno implies that a file doesn't or can't (currently) exist. (target_directory_operand): Use the new function to expand the set of errors we handle. * tests/ln/sf-1.sh: Add test cases for the newly handled errors. * THANKS.in: Mention the reporter. * NEWS: Mention the bug fix.
2014-01-14tests: restrict a recent SELinux test to SELinux systemsPádraig Brady
* tests/cp/no-ctx.sh: Since the test diagnoses whether the intercepted lgetfilecon() calls are actually called or not, restrict the test to systems where that occurs. The test cases are minimal on non SELinux systems and should be well covered by other tests. Reported-by: Bernhard Voelker
2014-01-13copy: fix a segfault in SELinux context copying codeNicolas Iooss
* src/selinux.c (restorecon_private): On ArchLinux the `fakeroot cp -a file1 file2` command segfaulted due to getfscreatecon() returning a NULL context. So map this to the sometimes ignored ENODATA error, rather than crashing. * tests/cp/no-ctx.sh: Add a new test case. * tests/local.mk: Reference the new test. * NEWS: Mention the fix. Fixes http://bugs.gnu.org/16335
2014-01-13maint: tests: refactor gcc commands for building shared libPádraig Brady
* init.cfg (gcc_shared_): A new function refactored from tests. (require_gcc_shared_): Adjust to call gcc_shared_() to build the test library, and remove that library before the function returns. * tests/cp/nfs-removal-race.sh: Call the new gcc_shared_(). * tests/df/no-mtab-status.sh: Likewise. * tests/df/skip-duplicates.sh: Likewise. * tests/ls/getxattr-speedup.sh: Likewise. * tests/rm/r-root.sh: Likewise.
2014-01-13copy: fix SELinux context preservation for existing directoriesPádraig Brady
* src/copy.c (copy_internal): Use the global process context to set the context of existing directories before they're populated. This is more consistent with the new directory case, and fixes a bug for existing directories where we erroneously set the context to the last copied descendent, rather than to that of the source directory itself. * tests/cp/cp-a-selinux.sh: Add a test for this case. * NEWS: Mention the fix. * THANKS.in: Add reporter Michal Trunecka.
2014-01-09tests: avoid FP failure when cp fails for /proc/cpuinfoBernhard Voelker
On emulated aarch64 systems like in the qemu-based OpenBuildService of openSUSE, cp fails to copy /proc/cpuinfo because the inode number changes between the initial stat() call and copying the file: $ cp /proc/cpuinfo exp cp: skipping file '/proc/cpuinfo', as it was \ replaced while being copied * tests/cp/proc-zero-len.sh: When cp fails, check on the above error message to skip the test.
2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2014-01-02build: update gnulib submodule, bootstrap and tests/init.sh to latestBernhard Voelker
* gnulib: Update to latest. * bootstrap: Update from gnulib. * tests/init.sh: Likewise.
2013-12-13tests: avoid unlikely deadlock in dd/no-allocate on some shellsPádraig Brady
* test/dd/no-allocate.sh: Use 'wait' to ensure we don't have multiple writers to the fifo, which was seen to trigger a very hard to reproduce deadlock with make -j20 on solaris. Also avoid writing to the fifo with the shell; instead using dd. (check_dd_seek_alloc): A new function refactored from the various cases, which are now constructed from function parameters.
2013-12-13tests: restrict cp --link inode comparisons to compatible systemsPádraig Brady
* tests/cp/link-deref.sh: On systems were cp can't determine if gnulib linkat() emulation might create a symlink instead of a hardlink to a symlink, copy.c will create a symlink to the symlink so that it has more control over its metadata. Also even if the system supports this operation, the particular file system under test may not. So avoid the hardlinked symlink verification in these cases. This fixes a false failure on aix, solaris and freebsd.
2013-12-11tests: df/total-unprocessed: fix false failure with lofsPádraig Brady
* tests/df/total-unprocessed.sh: Skip the test when we can't determine the file system type as the exclusion filter is not applied in that case. "lofs" being ignored is effectively an unknown file system type.
