Let's add a way to get the type-specific D-Bus interface of a unit from
either its type or name to src/basic/unit-name.[ch]. That way we can
share it with the client side, where it is useful in tools like cgls or
machinectl.
Also ports over machinectl to make use of this.
It's really confusing if stdout goes to the pager, but stderr is written
directly to the screen. Hence, make sure both stdout and stderr are
passed to the pager when doing autopaging.
Apparently, sendfile() does not work between fifos and ttys, but
splice() does, hence let's optionally fall back to that. This is useful
to implement the fallback pager this way.
Querying low-level DNS RRs should be done via resolved now, not via
glibc's awful res_query() API anymore. Let's not introduce an async
wrapper for it hence.
When handing out DHCP leases, try to propagate DNS/NTP server
information from "uplink". The "uplink" is automatically determined as
the network interface with the highest priority default route on it.
We should not fall back to dbus-1 and connect to the proxy when kdbus
returns an error that indicates that kdbus is running but just does not
accept new connections because of quota limits or something similar.
Based on a patch by Kay.
This reverts commit d4d00020d6. The idea of
the commit is broken and needs to be reworked. We really cannot reduce
the bus-addresses to a single address. We always will have systemd with
native clients and legacy clients at the same time, so we also need both
addresses at the same time.
It is not acceptable to load unit files during enable/disable operations
just to figure out the selinux labels. systemd implements lazy loading
for units, so the selinux hooks need to follow it.
This drops the mac_selinux_unit_access_check_strv() helper which
implements a non-acceptable policy check. If anyone cares for that
functionality, you really should pass a callback+userdata to the helpers
in src/shared/install.c which does policy checks on each touched file.
See #1050 on github for more.
We use dashes in our bloom-tags. Make sure the newly introduced arg0has
tag uses the same style.
Note that the external dbus-tags don't use dashes, though. They are
defined in the spec and we need to keep compatibility there.
a) drop handling of obsolete or unused DHCP options time_offset,
mtu_aging_timeout, policy filter, mdr, ttl, ip forwarding settings.
Should this become useful one day we can readd support for this.
b) For subnet mask and broadcast it is not always clear whether 0 or
255.255.255.255 might be valid, hence maintain a boolean indicating
validity next to it.
c) serialize/deserialize broadcast address, lifetime, T1 and T2 together
with the rest of the fields in dhcp_lease_save() and
dhcp_lease_load().
d) consistently return ENODATA from getter functions for data that is
missing in the lease.
e) add missing getter calls for broadcast, lifetime, T1, T2.
f) when decoding DHCP options, generate debug messages on parse
failures, but try to proceed if possible.
g) Similar, when deserializing a lease in dhcp_lease_load(), make sure
we deal nicely with unparsable fields, to provide upgrade compat.
h) fix some memory allocations
refcnt.h only exists for cases where objects are simultaneously handled
by different threads. Otherwise it should not be used. The only case
where this applies is sd_bus, really, and pretty much none of our APIs,
since we do not claim thread-safety for them.
When we make sd-dhcp public one day we really should not make
sd_dhcp_lease_save() and sd_dhcp_lease_load() public, since it's pretty
much only useful as internal utility for networkd itself.
