597da51bae tree-wide: make parse_ifindex simply return the index
We don't need a seperate output parameter that is of type int.  glibc() says
that the type is "unsigned", but the kernel thinks it's "int".  And the
"alternative names" interface also uses ints. So let's standarize on ints,
since it's clearly not realisitic to have interface numbers in the upper half
of unsigned int range.

0c020321c8 test-network: simplify wait_online() by calling wait_operstate()
The wait_operstate() function now rechecks the condition for a timeout,
so the wait_online() function can simply call it to check for the
setup_state.

a4632dc7d1 test-network: convert wait_operstate() to recheck condition for timeout seconds
Failing after a single check leads to extra sleeps scattered through
test cases, and can also lead to false failures.  Instead perform a
recheck for a number of seconds until the state matches, and fail only
if the timeout is exceeded.

This allows removing all the manual sleeps in the testcases.

4c64965257 network: drop foreign config after addr_gen_mode has been set
Interfaces may come up at any time, even during our initialization of
them, for various reasons; e.g. the kernel will raise VLAN when its
parent is raised; or we will raise an interface if configured with
BindCarrier and its associated interfaces come up.

When LinkLocalAddressing has been disabled for ipv6, we disable
addr_gen_mode in the kernel, so it will not automatically create a
ipv6ll address when the interface is raised.  However, we currently
drop all foreign addresses before disabling addr_gen_mode.

If the link has been up for a long time, then its kernel-created ipv6ll
address will be correctly dropped.  If the link is down, and stays
down until we raise it after finishing configuration, the addr_gen_mode
setting will be disabled when the interface is raised and the kernel
will not create any ipv6ll address.

However, if the interface is raised after dropping foreign config,
but before we have disabled addr_gen_mode, the kernel will create a
ipv6ll tentative address that will eventually finish DAD and become a
working ipv6ll address, even though we have been configured to disable
ipv6ll.

Moving our call to drop foreign addresses to after we have successfully
set addr_gen_mode closes this window; after we disable addr_gen_mode,
we can safely remove foreign ipv6ll addresses (including tentative ones)
and be sure that the kernel will not create any more.

Fixes: #13882.

0917a27178 network: if ipv6ll is disabled, enumerate tentative ipv6 addrs before dropping foreign addrs
The kernel will create an ipv6ll tentative address immediately when an
interface is raised if addr_gen_mode is not disabled; and, the kernel does
not notify netlink listeners about any tentative addresses.  So it's
possible for an interface to contain tentative ipv6 link-local address(es)
that networkd doesn't know about when all foreign addresses are dropped.

In this case, networkd is later notified about the new ipv6ll address(es)
after they finish DAD and are no longer tentative; but since that's after
networkd has already dropped foreign addresses, they are incorrectly left
on the interface.

9524014ee6 network: add link->setting_genmode flag
Similar to the link->setting_mtu flag, this delays continued configuration
until after the genmode has been successfully set; this is important
because we do not want networkd to raise the interface before the genmode
has been set, as if we're disabling the genmode, raising the interface
before we have successfully disabled the genmode will result in the kernel
creating a ipv6ll address, even though we don't want that.

3a390124b7 network: rename linux_configure_after_setting_mtu() to linux_configure_continue()

b63c88b627 man: describe "symlink" and "systemctl link" explicitly in UNIT FILE LOAD PATH
There are sometimes users who put unit files in a location that is inaccessible
when systemd starts although they are not found and thus not started because
the corresponding mount units have not activated yet.

There is already a warning for such issue in man 8 systemctl:

     link PATH...
         ...<snip>...
         The file system where
         the linked unit files are located must be accessible
         when systemd is started (e.g. anything underneath /home
         or /var is not allowed, unless those directories are
         located on the root file system).

However, it looks that it's difficult to find the warning because introductory
users typically doesn't know systemctl link.

Although there is a description in UNIT FILE LOAD PATH pointing to systemctl
link, symlink is now not explicitly mentioned there and thus users doesn't
easily get aware of they should read it.

To deal with this, let's describe "symlink" and "systemctl link" more
explicitly in UNIT FILE LOAD PATH.

4c2ef32767 core: propagate service state to socket in more load states
It makes sense to filter state changes for some load states that
shouldn't happen, but the common cases should be accepted, because they
might happen during runtime when "systemctl daemon-reload" is issued and
unit files changed state in between. Otherwise we lose events.

19212f2781 udev: don't import parent ID_FS_ data on partitions
When probing partitions, we inherit important information from the parent
disk device such as ID_MODEL, and usage of such properties is seen to
be acceptable and well established.

However, we need to exclude filesystem information from the properties
that get inherited. Information about the device content should not be
passed on in this way.

For example, Linux distro install media commonly uses an ISO filesystem
plus a partition table. The ISO filesystem is detected on the main disk
device, but we should not pass down those details to the partitions,
some or all of which may be pointing at storage areas completely distinct
from the ISO filesystem.

This is particularly problematic when adding new partitions on media
set up in this way (since the new partitions are then reported to contain
the parent device's ISO filesystem), or when dealing with more unusual
hybrid ISO layouts. The inaccuracy of information here inversely affects
users of blkid and udev's persistent storage symlinks.

Exclude ID_FS_* properties from the inheritance chain to avoid these
problems.
