> tree-wide: Use "unmet" for condition checks, not "failed"
Since I noticed when running `systemctl status` on a recent
systemd still seeing
`Condition: start condition failed`
To recap the original rationale here for "unmet" is that it's
normal for some units to be conditional, so the term "failure"
here is too strong.
Unlikely, but even if find_esp() or friends called with unnormalized or
relative 'root', let's make the result path normalized and absolute.
Note, before 63105f33ed, these functions
returned an absolute and normalized path. But the commit made the result
path simply concatenated with root.
Follow-up for 63105f33ed.
When extension is not specified, image class is not necessary to be
specified. Let's use _IMAGE_CLASS_INVALID as an indicator that no
extension is specified.
When path_find_first_component() returns the last component, the iterator
must be an empty string. The fact is heavily used in chaseat(). Let's
explicitly test it.
Previously, struct stat may not be correctly synced with the currently
opened fd, e.g. when a path contains symlink which points to an absolute
path.
This also rename variables for struct stat, to make them consistent with
the corresponding fd.
All tags are managed under /run/udev/tags, and the directories there are
named with tags. Hence, each tag must be a valid filename.
This also makes all validity check moved to sd-device side, and
makes failure caused by setting invalid tags non-critical.
With this change, an empty string cannot be assigned to TAG=, hence the
test cases are adjusted.
After manually editing /etc/locale.gen, calling localectl set-locale
sometimes fails. When it fails, the systemd journal shows:
systemd-localed: free() / invalid pointer.
It turned out that it only fails if some of the uncommented lines in
/etc/locale.gen have leading spaces, as in:
* C.UTF-8 <= OK
* en_US.UTF-8 <= OK
* fr_FR.UTF-8 <= NOK
After parsing a line from /etc/locale.gen, we use strstrip() to obtain
the "trimmed" line (without leading or trailing spaces).
However, we store the result of strstrip() in the original pointer
containing the untrimmed line. This pointer is later passed to free
(this is done automatically using _cleanup_free_).
This is a problem because if any leading space is present, the pointer
will essentially be shifted from its original value. This will result in
an invalid free upon cleanup.
The same issue is present in the locale_gen_locale_supported function.
Fixed by storing the result of strstrip() in a different pointer.
