We also shorten the logic by getting rid of the validate_node()
function. An extra check is added to verify we're dealing with
a device before calling sd_device_new_from_devname() since that
will return -EINVAL if anything other than a device is passed.
Instead of retrieving the new sysfs path in device_process_new(),
let's pass the syspath we retrieved earlier to device_process_new()
similar to how we do for other functions in core/device.c.
In the documentation, using the term "managed" for both the RA flag and
the DHCPv6 mode is confusing because the mode is referred to as
"solicit" both in the official DHCPv6 documentation (see RFC 8415) and
in the WithoutRA option.
Furthermore, calling the other RA flag "other information" or "other
address configuration" is confusing because its official name is simply
"other configuration" (see RFC 4861 and RFC 5175) and it isn't used to
assign IP addresses.
Rewrite the documentation for DHCPv6Client and WithoutRA to make it
clear that getting the "managed" RA flag triggers the same kind of DHCP
request as WithoutRA=solicit, whereas getting the "other configuration"
RA flag triggers the same kind of DHCP request as
WithoutRA=information-request.
Plain strv_split() should not care if the strings contains backslashes
or quote characters. But extract_first_word() interprets backslashes
unless EXTRACT_RETAIN_ESCAPE is given.
I wonder how it's possible that nobody noticed this before. I think this
code was introduced in 0645b83a40.
Fixup for a5efbf468c: if $COLORTERM was set, we'd
unconditionally turn on colors, which is unexpected and wrong. It even breaks
our own tests when executed in gnome-terminal.
This reverts commit d6c9411072.
I still think this is something that needs to be done, but we're hitting some
unexplained failures, e.g. https://github.com/systemd/systemd/issues/22920.
So let's revert this for now, so -rc2 can be released, with a plan to return
to this after a release.
Closes#22920.
With a recent change paths leaving the statically known lookup paths would be
treated differently then those that remained within those. That was done
(AFAIK) to consistently handle alias names. Unfortunately that means that on
some distributions, especially those where /etc/ consists mostly of symlinks,
would trigger that new detection for every single unit in /etc/systemd/system.
The reason for that is that the units directory itself is already a symlink.

The LLDP spec (IEEE 802.1AB) requires the three mandatory TLVs (Chassis
ID, Port ID, and TTL) to be the first three TLVs in the packet, in that
specific order, whereas systemd put the TTL near the end of the packet.
This violation caused the ethernet switch in our office to discard these
packets as malformed, and Wireshark's packet parser also chokes on them.

No need to involve a trivial shell script for this.
We could call the compiler directly, but test() expects arguments
to be passed separately and cc.cmd_array() can contain arguments
itself. Using env is easier than manually slicing the array because
meson has no builtins for that.
This is a follow-up for f470cb6d13 which in
turn is a follow-up for a068aceafb.
The latter started to honour hidden files when deciding whether a
directory is empty. The former reverted to the old behaviour to fix
issue #23220.
It introduced a bug though: when a directory contains a larger number of
hidden entries the getdents64() buffer will not suffice to read them,
since we just allocate three entries for it (which is definitely enough
if we just ignore the . + .. entries, but not ig we ignore more).
I think it's a bit confusing that dir_is_empty() can return true even if
rmdir() on the dir would return ENOTEMPTY. Hence, let's rework the
function to make it optional whether hidden files are ignored or not.
After all, I looking at the users of this function I am pretty sure in
more cases we want to honour hidden files.
In sd_network_monitor_flush(), we shouldn't remove the inotify
watch for the current directory if the directory the network
monitor is waiting for wasn't created yet.
inotify_add_watch() returns the same unique watch descriptor if a
path is already being watched. Let's return the watch descriptor
from monitor_add_inotify_watch() so we can check if it's the same
as the watch descriptor of the inotify event. If they are equal,
we're still watching the same path and we don't need to remove the
inotify watch just yet.
