We have not tested if the settings actually filter DHCP servers.
Let's add a test case for the settings.
Note, the .network file used here has been unused since
0730e3767d. So, we can freely reuse it
without changing other test cases.
Closes#30107.
This reverts commits 89e73ce86f and
543d2a4d45.
The commit assign "custom" to fixed DUID type 5. When making DUID fully
configurable, the type number should be also configurable. Also, the
fully custom DUID should be acceptable for DHCPv4.
- rename TCPRetransmissionTimeOutSec= -> TCPRetransmissionTimeoutSec,
- refuse infinity,
- fix the input value verifier (USEC_PER_SEC -> USEC_PER_MSEC),
- use DIV_ROUND_UP() when assigning the value.
Follow-ups for 1412d4a4fe.
Closes#28898.

Now, gateway for routes to DNS or NTP servers should be correctly picked,
hence it is not necessary to adjust the gateway address in
dhcp4_request_route_auto() again.
Also, similar for classless static routes, let's always honor
gateway address specified in (non-classless) static routes.
And if not found, refuse to configure the route.
If a DHCP server provides classless static or static routes, then we
should use the gateway for accessing a node in the range specified in
the route. E.g. if a DHCP server provides the default gateway is
192.168.0.1, and classless static route for 8.0.0.0/8 with gateway
192.168.0.2, then we should access 8.8.8.8 through 192.168.0.2 rather
than 192.168.0.1, but should use 192.168.0.1 for 9.9.9.9.
Fixes#28358.
This fixes regression introduced in 5a0c810462 with which all requests
for link properties ended up with EINVAL as we kept hitting
the signature_is_single() assert in sd_bus_get_property().
We create the udevadm -> systemd-udevd symlink during the install phase,
so it doesn't exist in the just compiled tree. This worked in CI since
the symlink is manually created there post-build.
From `ip-link(8)`:
> [no]ignore-df - enables/disables IPv4 DF
suppression on this tunnel. Normally datagrams
that exceed the MTU will be fragmented; the
presence of the DF flag inhibits this, resulting
instead in an ICMP Unreachable (Fragmentation
Required) message. Enabling this attribute causes
the DF flag to be ignored.
If this option is enabled for a GRE/GRETAP tunnel, the `DF` flag in the outer IP header
will not inherit the inner IP header's `DF` flag.
This is useful to transfer packets that exceed the MTU of the underlay
network.
This makes a bond or bridge interface in the degraded-carrier state but has a routable address
handled as routable operational state.
If the carrier is degraded but the address state is routable then the operational state should be
seen as routable and not degraded because that may be the case for bonds if some of the links are down,
but when that happens the bond as whole is still routable.
This also makes operational state to degraded if address state is degraded even if the link state is
degraded-carrier.
Fixes#22713.
Fixes a regression caused by ab3aed4a03.
I thought the commit does not cause any severe regression. However,
drivers for network interfaces may be loaded later. So, we should wait
if no network interface is found.
Fixes#27822.
The setting IPv6AcceptRA= is defaults to yes, hence, even if a .network
file for an interface has static IP address configuration, it may takes
few seconds for the interface being configured state, as NDisc for the
interface needs to be finished. That makes wait-online.service
needlessly slow. Typically, such delay is not necessary for statically
configured networks.
Let's make the required condition slightly relaxed; if a .network file
has static IP address configurations, then let's make the matching
interface enter the 'configured' state soon after the static addresses
configured on the interface.
Note, this does not change the default for IPv6AcceptRA=, hence, NDisc
still runs on interfaces by default. So, addresses, routes, DNS servers,
and so on based on RA will be assigned on interfaces later.
Strictly speaking, this breaks backward compatibility, but the previous
behavior is not clearly documented. If a user requested both static
IPv4 address and IPv6 SLAAC address configured before an interface being
entered to the 'configured' state, then '--ipv6' for wait-online can be
used. So, the behavior change should not cause severe regression.
Closes#27779.
The commit 0f707207b9 enables strong
warning about missing prefix length in Address= setting.
The change was done in v241, and was about 4 years ago.
Let's drop the legacy assumption and make the parser consistent with
'ip address' command.
C.f. #11307.
Closes#26102.
If another bound interface (dummy98) will be removed before that dummy99
is processed by udevd, then removing dummy98 in the next step makes the
target interface (test1) bring down.

The outstanding kernel panic should be already fixed in recent enough
kernels by [0]. To make the test safe to run anywhere, let's implement
a simple kernel version check and run the test only if we're running
with at least kernel 6.x. The patch might be in some 5.x kernels as
well, but let's be on the safe side and use 6.x as a baseline here
(which is currently the case for Arch and Fedora Rawhide anyway).

(s) is just ugly with a vibe of DOS. In most cases just using the normal plural
form is more natural and gramatically correct.
There are some log_debug() statements left, and texts in foreign licenses or
headers. Those are not touched on purpose.
That's not necessary. Moreover, if the socket units are stopped in
`setUpModule()`, then there exists a short timespan that we cannot call
`udevadm control`, as the control socket may not be opened yet.
If we run whole tests, then the first test is
NetworkctlTests.test_altname, and it calls `udevadm control` in `setUp()`.
Hence, the test may fail.

Several DHCP client tests change the system timezone.
Let's save the current timezone at the beginning, and restore it with
the saved value at the end.
- introduce several helper functions
- do not list unit files, but remove the runtime unit directory in
tearDown().
- do not list used interfaces, but remove all interfaces previously not
exists in tearDown().
- save routes and routing policy rules before running tests, and flush
unnecessary routes and rules in each tearDown() calls.
- drop many time.sleep() calls.
- call tearDown() after each sub tests.
- shorten code.
- several coding style fixes.
- etc, etc...
Hopefully, this improves performance of the test.
