Recent mount (since the switch to libmount in v2.22) drops the '=' in
mount options that are set to an empty value. For example, the command
line below will be affected:
# mount -o rw,myopt='' -t tmpfs tmpfs /mnt/tmp
Fix that by preserving an empty string in the options passed to the
mount(2) syscall when they are present on the command line.
Add test cases to ensure empty string handling is working as expected
and in order to prevent regressions in the future.
Also tested manually by stracing mount commands (on a kernel which
accepts a special extra option, for testing purposes.)
Before this commit:
# strace -e mount ./mount -t tmpfs -o rw,myopt='' tmpfs /mnt/tmp
mount("tmpfs", "/mnt/tmp", "tmpfs", MS_MGC_VAL, "myarg") = -1 EINVAL (Invalid argument)
After this commit:
# strace -e mount ./mount -t tmpfs -o rw,myopt='' tmpfs /mnt/tmp
mount("tmpfs", "/mnt/tmp", "tmpfs", MS_MGC_VAL, "myopt=") = 0
All test cases pass, including newly added test cases. Also checked
them with valgrind using:
$ tests/run.sh --memcheck libmount/optstr
Fixes #332.

Older Linux distributions came with differently incomplete
btrfs-tools 0.19+git versions (2009-2013). Old mkfs.btrfs
needs minimum device size 256M.
Note the most simple way to skip btrfs-tools < 3.14 would be
btrfs property --help 2>&1 || ts_skip "btrfs too old"
but I want to include 3.12 because of Ubuntu Trusty on travis.
This patch partly reverts/rewrites the following commits:
7e604f3c - tests: don't skip case "output undefined"
076153f8 - tests: don't compare btrfs mount options
370d31f7 - tests: skip btrfs tests if version too old

We don't control mount options in the mountinfo file and the options
depend on kernel version. It does not make sense to hardcode the
options in the expected outputs.
Note that libmount should be portable enough to be able to work with
all kernel versions. It seems better to check libmount functionality
than kernel mount options formatting.

Treat missing expected files as empty and let the test fail if
there is non-empty output.
Expected output may be missing in these cases:
1. forgot to commit the file after changing/adding a (sub)test
2. a bug in a test where we do tricks with TS_EXPECTED
3. and most notable if ts_die() is called before a subtest is
initialized, e.g. in ts_scsi_debug_init()
I always wondered why we don't treat this as FAILED. Now we do
so, ts_finalize and ts_gen_diff looks much cleaner now.
The change discovers that tests with subtest were ignoring the
"non-sub" expected files which had to be fixed. BTW we removed
any zero sized files.
Moreover now we respect diff's return value. In past all test
succeeded when diff was not able to write to diffdir, e.g. when
running tests as normal user after they run as root.

Very long mount lines from the kernel (either from escaping or from giant
option lists) could exceed BUFSIZ, leading to parsing failures. This
adds a test for the condition.

If the target directory (mountpoint) does not exist then mount(8) will create
it before mount.<type> is executed or mount(2) syscall is called.

The current way how add any comment or extra information to /etc/fstab
is to use comment="" mount option. This is not too elegant and readable
if you want to add more than one comment.
It seems better to add any generic prefix that will be used for all
3rd-party userspace mount options.
Expected syntax is:
x-<application>-<options>[=<data>]
For example:
x-systemd-bar=managed
All x-* options (as well as comment=) are ignored by libmount and not
stored to the mtab file.

The utab file is private libmount stuff. Anything about utab should
not be exported by library API.
