"left from <something>" is not correct. "left <something>" would be the
usual form, but "left master interface" is not clear at all. So reword
those messages totally.
Follow-up for 3881fd406b.
Even if we use meson >= 0.55, using path() does not produce any error or
warning if the required version is below 0.55.
Let's convert path() with full_path() when we requires meson >= 0.55.
Setting with number is deprecated:
```
meson.build:1008: DEPRECATION: configuration_data.set10 with number. the `set10` method should only be used with booleans
```
Passing potentially arbitrary data into a shellscript is potentially
very broken if you do not correctly quote it for use. This quoting must
be done as part of the interpretation of the data itself, e.g. python's
shlex.quote; simply formatting it into a string with double quotes is
NOT sufficient.
An alternative is to communicate the data reliably via argv to the shell
process, and allow the shell to internally handle it via `"$1"`, which
is quote-safe and will expand the data from argv as a single tokenized
word.
This fixes a minor bug introduced by 10af8bb24b.
Before the commit, the interface group was set only when Group= is explicitly
specified, otherwise the interface group was kept. However, after the commit,
we need to specify Group= with an empty string to keep the current interface
group.
This way we can connect correctly to any AF_UNIX socket in the file
system, and even save some code. Yay!
This also adds some test code for this, that ensures read_file_full()
works correctly for AF_UNIX sockets that violate the 108 char limit.
Supporting sockets like this kinda matters I think, for the simple
reason that apps want to build socket paths via XDG_RUNTIME_DIR and
suchlike, and we should be able to connect to them, even via
non-normalized paths.
This is a short helper for connecting to AF_UNIX sockets in the file
system. It works around the 108ch limit of sockaddr_un, and supports
"at" style fds.
This doesn't come with a test of its own, but the next patch will add
that.
let's not make up new errors in these checks that validate if connect()
work at all. After all, we don't really know if the ENXIO we saw earlier
actually is really caused by the inode being an AF_UNIX socket, we just
have the suspicion...
This way we can implement nice fallbacks later on.
While we are at it, provide a test for this (one that is a bit over the
top, but then again, we can never have enough tests).
The issue #12953 is caused by the following:
On switching root,
- deserialized_found == DEVICE_FOUND_UDEV | DEVICE_FOUND_MOUNT,
- deserialized_state == DEVICE_PLUGGED,
- enumerated_found == DEVICE_FOUND_MOUNT,
On switching root, most devices are not found by the enumeration process.
Hence, the device state is set to plugged by device_coldplug(), and then
changed to the dead state in device_catchup(). So the corresponding
mount point is unmounted. Later when the device is processed by udevd, it
will be changed to plugged state again.
The issue #23208 is caused by the fact that generated udev database in
initramfs and the main system are often different.
So, the two issues have the same root; we should not honor
DEVICE_FOUND_UDEV bit in the deserialized_found on switching root.
This partially reverts c6e892bc0e.
Fixes#12953 and #23208.
Replaces #23215.
