Some interfaces require that the DHCPOFFER message is sent via broadcast
if they can't receive unicast messages before they've been configured
with an IP address.
E.g., s390 ccwgroup network interfaces operating in layer3 mode face
this limitation. This can prevent the interfaces from receiving an
IP address via DHCP, if the have been configured for layer3.
To allow DHCP over such interfaces, we're introducing a new device
property ID_NET_DHCP_BROADCAST which can be set for those.
The networkd DHCP client will check whether this property is set
for an interface, and if so will set the broadcast flag, unless
the network configuration for the interface has an explicit
RequestBroadcast setting.
Besides that, we're adding a udev rule to set this device property
for ccwgroup devices operating in layer3 mode, which is the case
if the ID_NET_DRIVER property is qeth_l3.
Supercedes #18829
The test appears to be occasionally failing. It uses systemd-run to echo
'hello world' into a namespaced journal and then uses journalctl to look for it,
but it doesn't wait.
In the failed runs it can't find it, but the automated journal dump shows
the message at the end.
Use --wait to avoid races.
With some versions of the compiler, the _cleanup_ attr makes it think
the variable might be freed/closed when uninitialized, even though it
cannot happen. The added cost is small enough to be worth the benefit,
and optimized builds will help reduce it even further.
We intentionally do not inline initializations with definitions for
a bunch of _cleanup_ variables in tests, to ensure valgrind is triggered.
This triggers a lot of maybe-uninitialized false positives when -O2 and
-flto are used. Suppress them.
The commit 0b81225e57 makes that networkd
remove all foreign rules except those with "proto kernel".
But, in some situation, people may want to manage routing policy rules
with other tools, e.g. 'ip' command. To support such the situation,
this introduce ManageForeignRoutingPolicyRules= boolean setting.
Closes#19106.
Otherwise rebase-helper thinks we're are a dist-git repository,
replacing the generated git archive with PR changes with the tarball
found in the 'sources' file.
There are two ambiguity in the original description:
1. It will delay all RUN instructions, include builtin.
2. It will delay before running RUN, not each of RUN{program} instructions.
The test occasionally fails as the umount is not yet completed when
cryptsetup close is invoked.
Both cryptsetup and losetup have supported deferred cleanup for some
time now, so use it instead to avoid races.
