udev: net_id: Improve predictable names for SR-IOV virtual devices
With PCI SR-IOV, a number of virtual network devices can be enabled,
all of which share the same physical network device. Currently,
udev generates names for SR-IOV virtual functions as if they were
independent network devices.
With this change, the predictable network device naming code will
check if a network device is an SR-IOV virtual device, and will
generate a name based on the physical PCI device plus a "v%u"
suffix. This should improve readability and predictability of
device names.
Here is an example of how this change would affect naming:
before patch | after patch
-----------------------------
eno1 | eno1 onboard NIC, physical function
enp101s0f0 | eno1v0 onboard NIC, SR-IOV virtual func 0
enp101s0f1 | eno1v1 onboard NIC, SR-IOV virtual func 1

udev: net_id: search parent devices for PCI slot number
To generate predictable network device names, the code in
udev-builting-net_id.c tries to match the PCI device address
of the network device to the entries in /sys/bus/pci/slots.
However, sometimes the slot number is not associated the
network controller PCI device itself, but rather with one of
its parents.
This change will try to find a match in /sys/bus/pci/slots for
the parents of the PCI network device, if it doesn't find a
match for the device itself.

Partially revert "seccomp: add mmap and address family restrictions for MIPS" (#8563)
This reverts the mmap parts of
f5aeac1439d64905c7b1b57042c39589dd31e3a6,
but keeps the part which restricts address families which works
correctly.
Unfortunately the MIPS toolchains still do not implement PT_GNU_STACK.
This means that while the commit to restrict mmap on MIPS was "correct",
it had the side effect of causing pthread_create to fail because glibc tries
to allocate an executable stack for new threads in the absense of
PT_GNU_STACK. We should wait until PT_GNU_STACK is implemented in all
the relevant parts of the toolchain (at least gcc and glibc) before
enabling this again.

core: delay adding target dependencies until all units are loaded and aliases resolved (#8381)
Currently we add target dependencies while we are loading units. This
can create ordering loops even if configuration doesn't contain any
loop. Take for example following configuration,
$ systemctl get-default
multi-user.target
$ cat /etc/systemd/system/test.service
[Unit]
After=default.target
[Service]
ExecStart=/bin/true
[Install]
WantedBy=multi-user.target
If we encounter such unit file early during manager start-up (e.g. load
queue is dispatched while enumerating devices due to SYSTEMD_WANTS in
udev rules) we would add stub unit default.target and we order it Before
test.service. At the same time we add implicit Before to
multi-user.target. Later we merge two units and we create ordering cycle
in the process.
To fix the issue we will now never add any target dependencies until we
loaded all the unit files and resolved all the aliases.

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.

Previously the compression threshold was hardcoded to 512, which meant that
smaller values wouldn't be compressed. This left some storage savings on the

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.

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.
