db3d4222e9 varlink: add debug logging 
When something fails, we need some logs to figure out what happened.
This is primarily relevant for connection errors, but in general we
want to log about all errors, even if they are relatively unlikely.

We want one log on failure, and generally no logs on success.
The general idea is to not log in static functions, and to log in the
non-static functions. Non-static functions which call other functions
may thus log or not log as appropriate to have just one log entry in the
end.

`TAGS=="*:tag:*"`. So, the property must be always prefixed and suffixed

258190a0d5 mmap-cache: drop ret_size from mmap_cache_get() 
The ret_size result is a bit of an awkward optimization that in a
sense enables bypassing the mmap-cache API, while encouraging
duplication of logic it already implements.

It's only utilized in one place; journal_file_move_to_object(),
apparently to avoid the overhead of remapping the whole object
again once its header, and thus its actual size, is known.

With mmap-cache's context cache, the overhead of simply
re-getting the object with the now known size should already be
negligible.  So it's not clear what benefit this brings, unless
avoiding some function calls that do very little in the hot
context-cache hit case is of such a priority.

There's value in having all object-sized gets pass through
mmap_cache_get(), as it provides a single entrypoint for
instrumentation in profiling/statistics gathering.  When
journal_file_move_to_object() bypasses getting the full object
size, you don't capture the full picture on the mmap-cache side
in terms of object sizes explicitly loaded from a journal file.

I'd like to see additional accounting in mmap_cache_get() in a
future commit, taking advantage of this change.

4eb105fa4a pid1: stop making /dev noexec 
Quoting Andy Lutomirski:
> The upcoming Linux SGX driver has a device node /dev/sgx.  User code opens
> it, does various setup things, mmaps it, and needs to be able to create
> PROT_EXEC mappings.  This gets quite awkward if /dev is mounted noexec.

We already didn't use noexec in spawn, and this extends this behaviour to other
systems.

Afaik, the kernel would refuse execve() on a character or block device
anyway. Thus noexec on /dev matters only for actual binaries copied to /dev,
which requires root privileges in the first place.

We don't do noexec on either /tmp or /dev/shm (because that causes immediate
problems with stuff like Java and cffi). And if you have those two at your
disposal anyway, having noexec on /dev doesn't seem important. So the 'noexec'
attribute on /dev doesn't really mean much, since there are multiple other
similar directories which don't require root privileges to write to.

8bceafa777 network: do not reconfigure interface when the link gains carrier but udev not initialized it yet 
When an interface gains carrier but udev have not initialized the
interface or link_initialized_handler() has not been called yet,
then link_configure will be called twice. Thus LLDP client will be
configured twice, and triggers assertion.

55679e291c nss-resolve: initialize logging, log json errors 
When the .so module is loaded, it gets a separate copy of stuff in src/basic,
including the log level variables. So any logging settings are unaffected by
the loading program calling log_parse_environment() or such. Let's also parse
the environment here so that we can have nice logging.

Initialization is done from each exported function, and pthread_once_t is used
to avoid duplicate initialization. I didn't merge PROTECT_ERRNO into
NSS_ENTRYPOINT_BEGIN because UNPROTECT_ERRNO is called in a bunch of places
and it would feel strange to have PROTECT_ERRNO hidden, but not UNPROTECT_ERRNO.

The most interesting stuff in this module is the varlink messages, and any
potential errors in json. So let's enable json logging when debug messages are
enabled.

With those changes, figuring out the issue in
https://github.com/systemd/systemd/pull/17823 is trivial:

239952e890 cryptsetup: Fix crypto device missing issue after bootup 
Normally, the udev rules operate on "change" events. But when
coldplugging, there's an "add" event present. The udev rules have to
recognize this and do some actions in this particular situation, too.
Also, we don't want the nodes to be created prematurely on "add"
events while not coldplugging. The udev rules will check
DM_UDEV_PRIMARY_SOURCE_FLAG to see if the device was activated
correctly before and if not, it ignore the "add" event totally.
This way the udev rules can support udev triggers generating "add"
events (e.g. "udevadm trigger --action=add" or
"echo add > /sys/block/<dm_device>/uevent").

In this case, the udevd service is started after
systemd-cryptsetup@config.service, is started, which will cause udevd
service to miss the "change" uevent with DM_UDEV_PRIMARY_SOURCE_FLAG
flag generated by systemd-cryptsetup@config.service. To solve this
issue, we let the cryptsetup service be started after the udevd
service.

104fc4be11 mmap-cache: bind prot(ection) to MMapFileDescriptor 
There are no mmap_cache_get() users that actually deviate prot
from the JournalFile's f->prot.

So there's no point in making this a separate parameter to
mmap_cache_get(), nor is there any need to store it in
JournalFile's f->prot.

Instead just pass it to mmap_cache_add_fd() at MMapFileDescriptor
creation, storing it in there for the mmap() callers, which
already receive MMapFileDescriptor *.

For functions receiving both an MMapFileDescriptor * and prot,
the prot argument has been simply removed and call sites updated.

Formalizing this fd:prot binding at the public API also enables
discarding the prot check in window_matches(), which is a hot
function on long window lists, so a minor CPU efficiency gain
should be had there as seen with the past removal of the fd
check.  Unnoticable for uncached journals, but maybe a little
runtime improvement when cached in specific circumstances.

window_matches_fd() has also been simplified to treat the
MMapFileDescrptor * as equivalent to its fd and prot.
