network: fix race between RTM_NEWLINK and NL82011_CMD_NEW_INTERFACE
When a new wireless network interface is created by the kernel, it emits
both RTM_NEWLINK and NL80211_CMD_NEW_INTERFACE. These events can arrive
in either order and networkd must behave correctly in both cases.
The typical case is that RTM_NEWLINK is handled first, in which case
networkd creates a Link object and starts tracking it. When the
NL80211_CMD_NEW_INTERFACE message is handled, networkd then populates
the Link object with relevant wireless properties such as wireless
interface type (managed, AP, etc.).
In the event that the order is reversed however, networkd will fail to
populate these wireless properties because at the time of processing the
nl80211 message, the link is considered unknown. In that case, a debug
message is emitted:
systemd-networkd[467]: nl80211: received new_interface(7) message for link '109' we don't know about, ignoring.
This is problematic because after the subsequent RTM_NEWLINK message,
networkd will have an incomplete view of the link. In particular, if a
.network configuration matches on some of the missing wireless
properties, such as WLANInterfaceType=, then it will never match.
The above race can be reproduced by using the mac80211_hwsim driver.
Suppose that there exists a .network configuration:
[Match]
WLANInterfaceType=ap
...
Now loop the creation/destruction of such an AP interface:
while true
do
iw dev wlan0 interface add uap0 type __ap
iw dev uap0 del
done
The above debug message from networkd will then be observed very
quickly. And in that event, the .network file will fail to match.
To address the above race, have the nl80211 message handler store the
interface index in a set in case a Link object is not found on
NL80211_CMD_NEW_INTERFACE. The handler for RTM_NEWLINK can then query
this set, and explicitly request the wireless properties from nl80211
upon the creation of the Link object.
systemctl is called many times by dnf or so, and missing /proc/ is not
a user's fault, but package manager's issue.

necessary.

journal: give the ability to enable/disable systemd-journald-audit.socket
Before this patch the only way to prevent journald from reading the audit
messages was to mask systemd-journald-audit.socket. However this had main
drawback that downstream couldn't ship the socket disabled by default (beside
the fact that masking units is not supposed to be the usual way to disable
them).
Originally, people used "extend a PCR with a measurement" or
"measure some blob into the PCR". In our docs those uses got merged
into "extend a string into a PCR". The meaning is clear to developers, but
it's a very jargony syntax that wouldn't make any sense to somebody who encounters
it the first time. Let's return to the more natural original phrasing.
Also, change various "this is supposed to act as" to "this acts as". If it
doesn't work, we have a bug to fix. This indirection is not useful.
Also, "boot path" → "phase path" and other smaller cleanups.

tree-wide: fix return value handling of base64mem()
This returns an ssize_t, not an int. On populare archs that's the
difference between 64bit and 32bit. hence, let's be more careful here,
and not silently drop half the bits on the ground by assigning the
return value to "int".
These wrap RELOADING=1 and STOPPING=1 messages. The former is
particularly useful, since we want to insert the MONOTONIC_USEC= field
into the message automatically, which is easy from C but harder from
shell.
udevd: implement the full Type=notify-reload protocol
We are basically already there, just need to add MONOTONIC_USEC= to the
RELOADING=1 message, and make sure the message is generated in really
all cases.
pid1: make sure we send our calling service manager RELOADING=1 when reloading
And send READY=1 again when we are done with it.
We do this not only for "daemon-reload" but also for "daemon-reexec" and
"switch-root", since from the perspective of an encapsulating service
manager these three operations are not that different.
We converted to not using #ifdef for most of our defines because the syntax is
nicer and we are protected against typos and can set -Werror=undef. Let's do
the same for SD_BOOT. The define is nicely hidden in build.h for normal builds,
and for EFI builds we were already setting SD_BOOT on the commandline.
Our HAVE_* variables are defined to 0 or 1, so '#if defined(HAVE_*)' is always true.
The variable is not defined when compiling for EFI though, so we need the
additional guard.
(I don't want to do something like add -DHAVE_EXPLICIT_BZERO=0 to the commandline
in src/efi/boot/meson.build, because this quite verbose. Our compilation commandlines
are very long already. Let's instead keep this localized in this one spot in the
source file.)x

journal: enforce strict consistency for realtime timestamps on write
Ensure all realtime timestamps in a journal file are strictly
ordered on write as a defense-in-depth measure. All known callers of
journal_file_append_entry and journal_file_copy_entry, which call this
function, should be able to handle the error by rotating the journal.
This is especially helpful for systems with RTC local time enabled,
where all log entries from initramfs might be recorded as several hours
later than it actually is, which won't get caught by journald during log
flushing. In those cases, the resulting inconsistency can cause libsystemd
to loop infinitely through journal files as observed in
`abrt-dump-journal-oops`.
