91b14d6ff3 resolved: reference count the dns servers
We want to reference the servers from their active transactions, so make sure
they stay around as long as the transaction does.

f5f07dbf06 networkd: tap add support for vnet_hdr
This patch adds support to configure IFF_VNET_HDR flag
for a tap device. It allows whether sending and receiving
large pass larger (GSO) packets. This greatly increases the
achievable throughput.

818ef443f0 resolved: make LLMNR checks conditional
Make all LLMNR related packet inspections conditional to p->protocol.
Use switch-case statements while at it, which will make future additions
more readable.

8b757a3861 resolved: separate LLMNR specific header bits
The C and T bits in the DNS packet header definitions are specific to LLMNR.
In regular DNS, they are called AA and RD instead. Reflect that by calling
the macros accordingly, and alias LLMNR specific macros.

While at it, define RA, AD and CD getters as well.

e43a8393ea dhcp: add support for vendor specific DHCP option
This adds support for option 43 (Vendor Specific Information) to
libsystemd-network DHCP code. The option carries an opaque object of n
octets, interpreted by vendor-specific code on the clients and
servers.

30494563f2 basic: util - fix errorhandling in unhexmem()
We were ignoring failures from unhexchar, which meant that invalid
hex characters were being turned into garbage rather than the string
rejected.

Fix this by making unhexmem return an error code, also change the API
slightly, to return the size of the returned memory, reflecting the
fact that the memory is a binary blob,and not a string.

For convenience, still append a trailing NULL byte to the returned
memory (not included in the returned size), allowing callers to
treat it as a string without doing a second copy.

aa1169774b Use a top-to-bottom numbering scheme for generating ids of subheadings and terms.
This scheme fixes permalinks to distinguish between items that would previously have the same ID attribute.

Where possible the generated ID values are the same as those generated with the previous versions of the stylesheet
to retain backwards compatibility with published links.

As a side effect of the changes xsltproc should no longer complain about duplicate IDs during build.

a05185279b sd-dhcp-lease: fix handling of multiple routers
currently if a dhcp server sends more than one router, sd-dhcp-lease
does not copy the ip because it assumes it will only ever be 4 bytes. a
dhcp server could send more than one ip in the router list, so we should
copy the first one and ignore the rest of the bytes.

559b5cc273 logind: bring bus policy up-to-date
A while back we opened up all of logind's bus calls to unprivileged
users, via PK. However, the dbus1 policy wasn't updated accordingly.

With this change, the dbus1 policy is opened up for all bus calls that
should be available to unprivileged clients.

(also rearranges some calls in the vtable, to make more sense, and be in
line with the order in the bus policy file)

Fixes #471.

e6494a07cb logind: rename 'pos' to 'position'
Spell out the proper name. Use 'pos' over 'position', and also update the
logind state file to do the same. Note that this breaks live updates.
However, we only save 'POSITION' on non-seat0, so this shouldn't bother
anyone for real. If you run multi-seat setups, you better restart a
machine on updates, anyway.

cc85d56245 logind: allow greeters to take over VTs
Make sure a greeter can forcefully spawn a session on a VT that is
in-use. A recent patch prevented this (this used to be possible for all
session types) as it is highly fragile. However, as it turns out,
greeters seem to rely on that feature. Therefore, make sure we allow it
explicitly for greeters.

ac59f0c12c units: emergency.service: wait for plymouth to shut down
Merely calling "plymouth quit" isn't sufficient, as plymouth needs some time to
shut down. This needs plymouth --wait (which is a no-op when it's not running).

Fixes invisible emergency shell with plymouth running endlessly.

8b258a645a tmpfiles: don't recursively descend into journal directories in /var
Do so only in /run. We shouldn't alter ACLs for existing files in /var,
but only for new files. If the admin made changes to the ACLs they
shouls stay in place.

We should still do recursive ACL changes for files in /run, since those
are not persistent, and will hence lack ACLs on every boot.

Also, /var/log/journal might be quit large, /run/log/journal is usually
not, hence we should avoid the recursive descending on /var, but not on
/run.

c01ff965b4 nss-mymachines: map userns users of containers to real user names
Given a container "foo", that maps user id $UID to container user, using
user namespaces, this NSS module extenstion will now map the $UID to a
name "vu-foo-$TUID" for the translated UID $UID.

Similar, userns groups are mapped to "vg-foo-$TGID" for translated GIDs
of $GID.

This simple change should make userns users more discoverable. Also,
given that many tools like "adduser" check NSS before allocating a UID,
should lower the chance of UID range conflicts between tools.
