- RTA_OIF has no business in the routing-rule policy. It is numerical
identical to FRA_GOTO. Fix using the correct enum value. Note that
RTA_OIF/FRA_GOTO was not used by networkd, and the type was already
correct at uint32. So, there is no change in behavior.
- RTA_GATEWAY also does not belong to the routing-rules. It is numerical
identical to FRA_UNUSED2. Obviously, that value is unused as well,
so there is no actual change in behavior either. In particular
that is because:
- kernel would not send messages with FRA_UNUSED2 attribute.
- networkd would not try to parse/send RTA_GATEWAY/FRA_UNUSED2
attributes.

CID #139583: plen + 1 is evaluated as int, and could in principle overflow.
So cast to ssize_t and add an additional check that our overflow calculation
doesn't overflow itself.
This also set lower log level for the messages.
6e2efb6c73 introduces the log messages.
But udevd may be started with --resolve-names=never, and the behavior
is expected.
Fixes#11720.
Fix section header for stable branches and backports. All the other
headings end in a colon and have no blank lines between them and the
body of the section, so fix this one accordingly.
Some tests will create a subtree of /sys under build/test/sys and
depending on the local system that tree might end up having an infinite
chain of symlinks. For example:
$ ls build/test/sys/devices/pnp0/00:00/subsystem/devices/00:00/subsystem/devices/00:00/subsystem/devices/00:00/subsystem/devices/00:00/subsystem/devices/00:00/subsystem/
devices drivers drivers_autoprobe
Exuberant ctags will by default follow symlinks, so configure it not to
do so through a local .ctags file setting --links=no.
Tested that `ctags -R` doesn't get stuck with the dotfile present.
Linux can be run on a device meant to act as a USB peripheral. In order
for a machine to act as such a USB device it has to be equipped with
a UDC - USB Device Controller.
This patch adds a target reached when UDC becomes available. It can be used
for activating e.g. a service unit which composes a USB gadget with
configfs and activates it.
Fixes: #11422
Oneshots going to inactive directly without ever entering UNIT_ACTIVE is
considered success. This however means that if something both Requires=
and Requisites= a unit of such nature, the verify-active job getting
merged into the start job makes it lose this property of failing the
depending jobs, as there, the start job has the result JOB_DONE on
success, so we never walk over RequisiteOf units.
This change makes sure that such units always go down. It is also only
meaningful with After=, but so is Requisite= itself. Also, we also catch
cases like a oneshot having RemainAfterExit= true making us start up
properly in such a setting, but then removing it, reloading the unit,
and restarting it. In such a case, we go down due to restart propagation
before them, and our start job waits on theirs, properly failing with
the JOB_DEPENDENCY result.
This covers cases where ConditionXYZ= creates a similar situation as
well.
According to the specification[1] the 'capabilities' describe the physical
device as a whole and the 'device_caps' describe the current device node.
The existence of 'device_caps' is indicated by the V4L2_CAP_DEVICE_CAPS
capability flag.
Use the 'device_caps' if available to generate the correct
ID_V4L_CAPABILITIES for the current device node.
This is relevant for UVC devices with current kernels: Two /dev/videoX
devices exist for those. One for video and one for metadata. The
V4L2_CAP_VIDEO_CAPTURE flag is present in the 'capabilities' for both
device nodes but only in the 'device_caps' of the video device node.
Without this, the ID_V4L_CAPABILITIES of the metadata device node
incorrectly contains 'capture'.

The "chaddr" field is 16 bytes long, with "hlen" being the
length of the address.
https://tools.ietf.org/html/rfc2131#section-4.3.1 says:
The server MUST return to the client:
...
o Any parameters specific to this client (as identified by
the contents of 'chaddr' or 'client identifier' in the DHCPDISCOVER
or DHCPREQUEST message), e.g., as configured by the network
administrator,
It's not clear, whether only the first 'hlen' bytes of 'chaddr'
must correspond or all 16 bytes.
Note that https://tools.ietf.org/html/rfc4390#section-2.1 says for IPoIB
"chaddr" (client hardware address) field MUST be zeroed.
with having "hlen" zero. This indicates that at least in this case, the
bytes after "hlen" would matter.
As the DHCP client always sets the trailing bytes to zero, we would expect
that the server also replies as such and we could just compare all 16 bytes.
However, let's be liberal and accept any padding here.
This in practice only changes behavior for infiniband, where we
previously would enforce that the first ETH_ALEN bytes are zero.
That seems arbitrary for IPoIB. We should either check all bytes or
none of them. Let's do the latter and don't enforce RFC 4390 in this
regard.
Cloudflare public DNS service is currently the fastest one according to
https://www.dnsperf.com/#!dns-resolvers. Why not improve the experience for
systemd users using this as a default fallback nameserver?
