Subject: [PATCH] networkd dhcpv4 logging endian fix
On a big-endian host, systemd-networkd prints out IPv4 network
addresses byte reversed:
Feb 10 16:43:32 hostname systemd-networkd[151]: eth0 : DHCPv4 address 158.1.24.10/16 via 1.1.24.10
The address obtained is 10.24.1.158/16 and the route is
10.24.0.0/16 dev eth0 src 10.24.1.187
The macro ADDRESS_FMT_VAL() unpacks a "struct in_addr" in a
little-endian specific manner.
This patch forces the passed address into host order, then unpacks it.
On an x86 later than i486, compiled with -O2, the only extra overhead
is a single bswap instruction.
Pass around Link objcets rather than FdbEntry objects. The link objects have an up-to-date
ifname we can use for logging. match_name sholud _never_ be used for anything except
matching. Firstly, it may be unset (usually is), and secondly it may not be up-to-date.
As a malloc0 could fail, doing a strncpy without checking could
cause issues. Adding an assert should be good enough and in line
with other similar routines in the code.

Leave it to the compiler to figure out whether it shall inline stuff or
not.
Only place where using static inline is OK to use is in in header
files, really.
For now we only support the hardcoded values RT_SCOPE_{UNIVERSE,LOCAL,HOST},
and not numerical values or values from /etc/iproute2/rt_scopes.
This addresses https://bugs.freedesktop.org/show_bug.cgi?id=88508.
This allows the admin to set the host-specific part of IPv6 addresses, but still
receive the prefix via SLAAC.
.network file snippet:
[Network]
IPv6Token=::12
gives:
$ ip token
token ::12 dev eth0
This closes https://bugs.freedesktop.org/show_bug.cgi?id=81177.
This allows both IPv4 and IPv6 link-local addresses to be enabled or disabled. By default
we still enable IPv6LL and disable IPv4LL. The old config option is kept for backwards
compatibility, but removed from the documentation.
Object path components must start with [A-Za-z_] (AFAIK).
Also the value of 'p' is undefined if asprintf fails.
Compare to user_bus_path() in src/login/logind-user-dbus.c:281.
not while applying the parsed sysctl values. Otherwise
info "Overwriting earlier assignment of %s in file %s" is
visible many times even though the given --prefix doesn't
try to set the overridden value.
This also optimizes the startup tiny bit since we have udev
rules running on network devices and setting sysctl through
the rules.
For the entries listed in the first column of language-fallback-map,
the entry from the second column will be used for LANGUAGE=, if
LANGUAGE= is not explicitly specified.

This map will be used to provide a fallback for translations.
For example, a Niederdeutsch (nds) speaker prefers to fall back to
German (de) translations rather then the English (C) ones.

We will be woken up on rtnl or dbus activity, so let's just quit if some time has passed and that is the only thing that can happen.
Note that we will always stay around if we expect network activity (e.g. DHCP is enabled), as we are not restarted on that.
Only the very basics, more to come.
For now:

If we get a NEWLINK + NEWADDR between enumerating the links and enumerating the addresses, we
would get a warning that the link corresponding to the address does not exist. This is a false
warning as both the NEWLINK and NEWADDR would be processed after enumerating completed, so drop
it.
- report actual load error for units which could not be loaded
- make unit_find_paths() report all kinds of errors it encounters
(for consistency)
- consistently handle not-found errors in cat() and edit()
