Some distributions still use glibc's libcrypt. In that case, libcrypt.pc
does not exist and dependency() will fail.
Also, even if libxcrypt is used, there may not be a symlink
from libcrypt.pc to libxcrypt.pc. So, let's add a secondary name.
Follow-up for d625f717db.
Fixes#28289.
When a static null address is requested, e.g. Address=0.0.0.0/24,
then the corresponding Address object owned by Network object has
null address, and previously it did not match any addresses already
assigne to the interface.
Let's search matching Address object when originally it is requested as
the null address.
Then, the address configured with requested as a null address will be
kept on reconfigure.
Fixes#26113.
Request may refer Address object owned by Link, but its broadcast
address or label may be updated by address_equalify(), hence these
fields cannot be used in the hash and compare functions.
Before this patch, if a network has multiple routers and one of them
provides a captive portal, then the portal was overwritten or cleared
when another RA from another router is received.
This makes captive portals managed in the similar way as DNS servers or
DNS domains. So now captive portal can safely handled even if a network
has multiple routers.
The change is intended to reproduce the issue #27983, though the
original issue is highly racy, and the test does not reproduce it
reliably. But, anyway, it is better to change the partition label to
test the devlink removal.
Follow-up for 381f6d4ba5.
When the function is called, the device may be already removed, and
another device has the same syspath. Such situation can occur when a
partition removed and another is created. In that case, the sysfs paths
of the removed and newly created partitions can be same, but their
devnums are different, and thus the database files corresponding to the
devices are also different.
Fixes#27981.
Follow-up for 123c0e24dd.
Note, the entry was originally added for IdeaPad Flex 5 in
21b589a155.
Then, a bug introduced by 19db450f3a.
But, when it was fixed by 738a195bd5,
the glob becomes too stricter, and another variant was added by
123c0e24dd.
When we request an address that already exists and is under removing,
we need to wait for the address being removed. Otherwise, configuration
of a route whose preferred source is the address will fail.
Fixes#28009.
Replaces #28088.

- add reference to initrd-battery-check.service in man page, and move
its section from 1 to 8,
- add link to man page in help message,
- introduce ERRNO_IS_NO_PLYMOUTH(),
- propagate error in battery_check_send_plymouth_message(),
- rename battery_check_send_plymouth_message() -> plymouth_send_message(),
- return earlier when the first battery level check passed to reduce
indentation,
- fix potential use of invalid fd on battery restored,
- do not use emoji for /dev/console,
- add simple test (mostly for coverity),
etc, etc...
This also drops the fallback for libacl, libcap, libcrypt, and libgcrypt,
as recent Ubuntu (at least, 20.04 LTS and newer) and Debian (at least, buster
and newer) have relevant .pc files.
Fixes#28161.
This also merges two arrays units and in_units, and uses dictionary
for declaring units.
This also fixes the condition handling, that previously only two
conditions were handled and rests were ignored.
We use usec_t for storing time value, which is 64bit.
However, usleep() takes useconds_t that is (typically?) 32bit.
Also, usleep() may only support the range [0, 1000000].
This introduce usleep_safe() which takes usec_t.
From changelog of dnsmasq v2.87:
====
Note in manpage the change in behaviour of -address. This behaviour
actually changed in v2.86, but was undocumented there. From 2.86 on,
(eg) --address=/example.com/1.2.3.4 ONLY applies to A queries. All other
types of query will be sent upstream. Pre 2.86, that would catch the
whole example.com domain and queries for other types would get
a local NODATA answer. The pre-2.86 behaviour is still available,
by configuring --address=/example.com/1.2.3.4 --local=/example.com/
====
We do not provide any way to override /etc/machine-info.
As the file is deprecated in kernel-install, let's skip to read it when
we test kernel-install.
Fixes#28011.
If multiple devices requested the same device node symlink with the same
priority, then previously we read O(N^2) of files saved in
/run/udev/links.
This makes if the requested symlink already exists with equal or higher
priority, then the symlink is kept, and skip to read all existing files,
except for one related to the current device node, in /run/udev/links.
Hence, the total amount of file read becomes O(N).
This improves performance of testcase_simultaneous_events_2 added by the
previous commit about 30%.
