Add a new flag to systemd-networkd-wait-online, --dns, to allow waiting
for DNS to be configured.
DNS is considered configured when at least one DNS server is accessible.
If a link has the property DefaultRoute=yes (either by explicit
configuration, or because there are no routing-only domains), or if the
search domain '.' is configured, wait for link-specific DNS to be
configured. Otherwise, global DNS servers may be considered.
Add a new method to io.systemd.Resolve.Monitor that allows subscribing
to changes in the systemd-resolved DNS configuration. The new method
emits the full DNS configuration (one entry for global configuration,
and one entry for each interface), any time the configuration is
updated.
The dbus property getter for DefaultRoute does not simply check
link->default_route. Instead, if l->default_route is not explicitly
configured, it checks dns_scope_is_default_route(l->unicast_scope).
Add a link_get_default_route() helper with this logic so that it can be
used for consistency.
We check this by opening a UDP socket and attempting to connect. We do
not send any traffic on it, but this will tell us if there are routes to
the DNS server.
This will be used in a later commit.
No functional change. Make it more clear that these varlink connections
are subscribed to query results. This prepares for adding SubscribeDNS
to the varlink API.
The varlink method io.systemd.Machine.Register() is in v256, hence type
of "leader" cannot be changed.
Let's revert the change by 755cb018c9, and
introduce another field "leaderProcessId", which takes detailed information
of the process.
Fixes a regression caused by 755cb018c9.
Fixes#36155.
tty_is_vc() is more often than not used for simple "categorization"
than validity check. E.g. in logind, we first recognize the tty
"looks like vc", and then use vtnr_from_tty() where range check
is performed and vtnr is extracted. In such cases, we want to reject
invalid vtnr from clients rather than silently carry on, hence
let's remove bound check in tty_is_vc().
Fixes#36166
Replaces #36167 and #36175
This introduces libmount_parse_mountinfo() and libmount_parse_with_utab().
The former one parses only mountinfo, but the latter one also parse
utab. Hopefully this avoids pitfalls like issue #35949.
Now that nspawn can run unprivileged off directory trees owned by
the new "foreign" UID range let's make sure homed actually allows
files owned by that range in the home directories.
This is not enough to make nspawn just work in homed home dirs
unfortunately though. that's because homed applies an idmapping, and
nspawn would need to then to take that idmapped mount and apply another
one, and the kernel simply doesn't support stacked idmapped mounts.
There's work ongoing to address that in the kernel.
However, this is a first step, and should be enough to make things just
work should the kernel eventually support stacked idmapped mounts.
An object json is a set of key and value pair, hence has its number of
element is multiple of two, and we know at least two elements there.
Follow-up for b6a2df6307.
Fixes CID#1590724
HACKING.md should first and foremost tell someone how to hack on
systemd, installing packages from OBS isn't the most likely section
a new contributor will be interested in, so let's move it further
down.
Then, we can avoid that files outside of sysfs are written by udev ATTR key.
This also makes
- logs failure in udev_resolve_subsys_kernel(),
- failure in sd_device_get_syspath() critical, as that should not happen,
- cache the value to be write when running on test mode, to make it
shown by OPTIONS="dump" or obtained by ATTR match token.
