2062ada74c selinux: let's fully (and statically) initialize log callback union (#8512) 
We can make this const and static, and initialize this ahead of time and
fully, hence let's do that.

12c2c56dcb nss-systemd: make dynamic users enumerable by getent 
This adds `setpwent()`, `getpwent_r()`, `endpwent()`, `setgrent()`,
`getgrent_r()`, and `endgrent()` interfaces to nss-systemd library.
Thus, dynamic users can be enumerated by e.g. `getent passwd` command.

e3c3d6761b core/load-fragment: reject overly long paths early 
No need to go through the specifier_printf() if the path is already too long in
the unexpanded form (since specifiers increase the length of the string in all
practical cases).

In the oss-fuzz test case, valgrind reports:
  total heap usage: 179,044 allocs, 179,044 frees, 72,687,755,703 bytes allocated
and the original config file is ~500kb. This isn't really a security issue,
since the config file has to be trusted any way, but just a matter of
preventing accidental resource exhaustion.

https://oss-fuzz.com/v2/issue/4651449704251392/6977

While at it, fix order of arguments in the neighbouring log_syntax() call.

e71d1f6c78 journal: don't insist that the journal file header's boot ID matches the last entry 
We update the boot ID whenever the file is opened for writing (i.e. set
to ONLINE stat), even if we never write a single entry to it. Hence,
don't insist that the last entry's boot ID matches the file header.

57850536d5 journal: provide compress_threshold_bytes parameter 
Previously the compression threshold was hardcoded to 512, which meant that
smaller values wouldn't be compressed. This left some storage savings on the
table, so instead, we make that number tunable.

3ceae1bc14 basic/fs-util: skip fsync_directory_of_file() if /proc/self/fd/ is not available (#8386) 
When systemd is running under lorax (in Fedora compose process), it'd think that
it failed to write /etc/machine-id, even though the write succeeded, because
fsync_directory_of_file() would fail, because /proc/self/fd/ is not available.
fsync_directory_of_file() is mostly an additional safety net, so I think it's best
to just silently ignore the error.

0441378080 nspawn: move network namespace creation to a separate step (#8430) 
Fixes #8427.

Unsharing the namespace in a separate step changes the ownership of
/proc/net/ip_tables_names (and related files) from nobody:nobody to
root:root. See [1] and [2] for all the details.

b454cfb05c mkosi: set file permissions in copy of source tree (#8370) 
Meson keeps permissions around during the build, so details of how umask
was set when cloning the original git tree will leak all the way to the
installed files in the mkosi image.

So reset the permissions of the files in the copy of the tree before
starting the build.

Also set the umask explicitly.

Tested by creating a mkosi image and booting it on a tree that was
cloned with a umask of 027, confirmed that the *.target files were not
created as world-unreadable anymore.
