This reverts commit d4b604baea.
When realloc() is called, the extra memory between the originally
requested size and the end of malloc_usable_size() isn't copied. (at
least with the version of glibc that currently ships on Arch Linux)
As a result, some elements get lost and use uninitialized memory, most
commonly 0, and can lead to crashes.
fixes#12384
1. When the DHCPv4 lease expires kernel removes the route. So add it back
when we gain lease again.
Closes https://github.com/systemd/systemd/issues/12426
2. When UseRoutes=false do not remove router
Many Logitech keyboards have the following special functions on F9-F12:
F9: file-browser F10: document-browser F11: image-browser F12:
music-browser. These should be bound to:
#define KEY_FILE 144 /* AL Local Machine Browser */
#define KEY_DOCUMENTS 235
#define KEY_IMAGES 0x1ba /* AL Image Browser */
#define KEY_AUDIO 0x188 /* AL Audio Browser */
This commit fixes the wrong binding of F12 to KEY_SOUND (which
translates to XF86AudioPreset) and removes the ?? comments from
both F11 and F12.
Add support for various custom key-codes emitted by the Logitech MX5500
keyboard, both when attached through its Bluetooth-receiver in USB-HID
proxy mode; and when connected as a Bluetooth device.

The upcoming kernel enumerates Logitech 27 MHz wireless keyboards and
mice by there wireless-PID, rather then using the PID of the receiver
which is the same for all 27MHz Logitech devices.
This allows us to add per model keymappings for the special keys on these
keyboards. This commit adds such mappings for the S520 keyboard
(modelnumber Y-RBA97).

This commit adds a default / fallback mapping, assigning the most common
meaning of the custom Logitech c10XX keycodes.
There's no point in running these transformation for certain files,
mainly anything from src/boot/efi and src/shared/linux, as this code
doesn't have access to our internal utility functions
For example, following transformation:
- isempty(s) ? NULL : s
+ empty_to_null(s)
would get applied to the empty_to_null function itself as well,
causing an infinite recursion, like:

If a container manager does not set $container, we could end up
in a strange situation when detect-virt returns container-other when
run as non-pid-1 and none when run as pid-1.
For example, the following transformation:

itself, which generates following nonsensical patch:

The link may not have corresponding .network file.
Note that in that case, link_ipv4ll_enabled() and link_dhcp4_enabled()
returns false. So, it is safe to drop the assertion.
Fixes#12422.
The `coccinelle/take-fd.cocci` transformation file attempts to rewrite
r = fd;
fd = -1;
to
r = TAKE_FD(fd);
Unfortunately, using `identifier` or `idexpression` as a metavariable
type in this case wouldn't match more complex location descriptions,
like:
x->fd = fd
fd = -1;
Using 'expression' metavariable type generates false positives,
as you can't specify scope of such expression. The only real example
from the current codebase is the global 'errno' variable, which results
in following patch generated by `spatch`:
--- src/basic/errno-util.h

Let's explicitly state that the matched expression should not equal
'errno' to avoid this. It's not particularly nice, but it should be
enough, at least for now.
Coccinelle needs a custom isomorphism file with rules (isomorphisms) how
to correctly rewrite conditions with explicit NULL checks (i.e.
if (ptr == NULL)) to their shorter form (i.e. if (!ptr)). Coccinelle
already contains such isomorphisms in its default .iso file, however,
they're in the opposite direction, which results in useless output from
coccinelle/equals-null.cocci.
With this fix, `spatch` should no longer report patches like:

When booting with "udev.log-priority=debug" for example, the output might be
spammed with messages like this:

While the message itself is useful, printing it per batch of events should be
enough.
By default, the available completions are sorted alphabetically, which
is counterproductive in case of syslog priorities. Override the default
behavior using the `nosort` option
When systemd is started, it detects initrd by checking for that file
The usage of that file is not documented anywhere, so mention it early
in the most relevant man-page I could find.
When we determine that a calendar expression cannot elapse anymore,
print a warning but proceed regardless like we normally would.
Quite possibly a remote system has a different understanding of time
(timezone, system clock) than we have, hence we really shouldn't change
behaviour here client side, but log at best, and then leave the decision
what to do to the server side.
