Zbigniew Jędrzejewski-Szmek e0c17a7d1b bus-message: fix negative offset with ~empty message 
In the linked reproducer, m->fields_size == 0, and we calculate ri == -1, which
of course doesn't end well. Skip the whole calculation if m->fields_size == 0,
and also check that we don't go negative even if it is non-zero.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=19446 and #15583.

David Wood 7354900ddd network: Fix split in SendOption= on client and server 
When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to
set the value of that option within the DHCP request that is sent out.
This differs to setting `DHCPServer.SendOption=`, which will place all
the options together as suboptions into the vendor-specific information
(code 43) option.

This commit adds two new config options, `DHCPv4.SendVendorOption=` and
`DHCPServer.SendVendorOption=`. These both have the behaviour of the old
`DHCPServer.SendOption=` flag, and set the value of the suboption in the
vendor-specific information option.

The behaviour of `DHCPServer.SendOption=` is then changed to reflect
that of `DHCPv4.SendOption=`. It will set the value of the corresponding
option in the DHCP request.

Stochastic Fairness Queueing is a classless queueing discipline.

The goal is to ensure fairness so that each flow is able to send data in turn,
thus preventing any single flow from drowning out the rest.

Zbigniew Jędrzejewski-Szmek 864edb39cf network: rename SendOptions= to SendOption= 
The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.

(The field in the data structure remains plural, because it actually stores
multiple values.)

Add `RuntimeMaxSec=` support to scope units (time-limited login sessions)
 2019-10-28 14:57:00 +01:00
Philip Withnall 9ed7de605d scope: Support RuntimeMaxSec= directive in scope units 
Just as `RuntimeMaxSec=` is supported for service units, add support for
it to scope units. This will gracefully kill a scope after the timeout
expires from the moment the scope enters the running state.

This could be used for time-limited login sessions, for example.

Siddharth Chandrasekara afe42aef39 dhcp4: make IPServiceType configurable 
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.
