The canonical DNS name ordering considers the rightmost label the most significant,
we were considering it the least significant. This is important when implementing
NSEC, which relies on the correct order.
|
|
Intended to be called repeatedly, and returns then successive unescaped labels
from the most to the least significant (left to right).
This is slightly inefficient as it scans the string three times (two would be
sufficient): once to find the end of the string, once to find the beginning
of each label and lastly once to do the actual unescaping. The latter two
could be done in one go, but that seemed unnecessarily convoluted.

networkd: capitalize VNetHeader= as VnetHeader=
|
|
|
|
This is handled by the kernel now that the socket is connect()ed.
|
|
This was a bug.
|
|
As we have connect()ed to the desired DNS server, we no longer need to pass
control messages manually when sending packets. Simplify the logic accordingly.
|
|
This function emits the UDP packet via the scope, but first it will
determine the current server (and connect to it) and store the
server in the transaction.
This should not change the behavior, but simplifies the code.
|
|
Even when we use shortened, combined words, we still should uppercase
where a new word starts. I couldn't find a canonically capitalized
version of this term, hence I think we should follow our naming rules
here.
|
|
No functional change, but makes follow-up patch clearer.
|
|
With access to the server when creating the socket, we can connect()
to the server and hence simplify message sending and receiving in
follow-up patches.
|
|
Close the socket when changing the server in a transaction, in
order for it to be reopened with the right server when we send
the next packet.
This fixes a regression where we could get stuck with a failing
server.
|
|
This was only ever used by LLMNR, so don't request this for unicast DNS packets.
|
|
A transaction can only have one socket at a time, so no need to distinguish these.

Each signal of the ObjectManager interface carries the path of the object
in question as an argument. Therefore, a caller will deduce the object
this signal is generated for, by parsing the _argument_. A caller will
*not* use the object-path of the message itself (i.e., message->path).
This is done on purpose, so the caller can rely on message->path to be
the path of the actual object-manager that generated this signal, instead
of the path of the object that triggered this signal.
This commit fixes all InterfacesAdded/Removed signals to use the path of
the closest object-manager as message->path. 'closest' in this case means
closest parent with at least one object-manager registered.
This fix raises the question what happens if we stack object-managers in
a hierarchy. Two implementations are possible: First, we report each
object only on the nearest object-manager. Second, we report it on each
parent object-manager. This patch chooses the former. This is compatible
with other existing ObjectManager implementations, which are required to
call GetManagedObjects() recursively on each object they find, which
implements the ObjectManager interface.

Add the PID we are proxying for, as well as the message's sender and
destination string, to the debug message that is printed when the proxy
drops unmatched broadcasts.
|
|
-i (aka --interface) takes an argument. Tell getopt_long() that, so that optarg
isn't NULL.

sd-boot: Show stub cmdline when edit (v2)

Justification is similar to BPDUGuard rename. "Positive" values
are easier. This is a rather uncommon option, so using a slightly
longer name should not be a problem, and may in fact may make it
easier to guess what the option does without reading the
documentation.

Looking at the kernel commit, "on" seems to be the default value:

bridge: Add a flag to control unicast packet flood.
Add a flag to control flood of unicast traffic. By default, flood is
on and the bridge will flood unicast traffic if it doesn't know
the destination. When the flag is turned off, unicast traffic
without an FDB will not be forwarded to the specified port.
... and it seems to be the reasonable thing to do by default.

Rename to follow the follow the style of other options.
In general "positive" options are preferred to "negative" ones,
because they are easier to describe and easier for humans to
parse (c.f. the shortening on the man page entry).
|
|
Old name was slightly misleading, because this flag does not determine
whether DSCP is used overall, but only if it is copied to the
decapsulated packet. Rename to better reflect that.
"Copy" does not imply direction. This is on purpose, because we might
later on enhance the setting to allow/disallow copying in the other
direction, to the encapsulated packet. If that is implemented,
CopyDSCP could understand additional values. This is nicer than
having two separate settings and follows the example of DHCP=.
Also, we try to avoid abbreviations, but we allow acronyms
like MTU, in DiscoverPathMTU=.
This setting was recently added, so it's fine to rename it without
backwards compat.

The expire timeout must be started/stopped if the corresponding mount unit
changes its state, e.g. it is started via local-fs.target or stopped by a
manual umount.
|
|
Return the token immediately instead. Otherwise the token is never returned
to the kernel, because the umount job is a noop and will not trigger a
state change.
|
|
Assigning a TPYE enum value to a class variable is certainly wrong.
However, they both have the same value, so the result was correct
nevertheless.

unquote_first_word: parse ` '' ` as an empty argument instead of no arg
|
|
automount: do not start expiration timer for TimeoutIdleSec=0
|
|
The timer value for automount unit specified with TimeoutIdleSec= is rounded
up to one second if that directive is set to 0.
Fix this by bailing early in automount_enter_runnning() in case no timeout is
requested.

Defaults to zero, which retains the current behaviour.

free() cannot be used with const pointers. However, our _cleanup_free_
handler features cast logic that hides that qualifier, so we don't get a
warning.
|
|
In bus_kernel_translate_message(), we print a DEBUG message on unknown
items. But right now, we also print this message for KDBUS_ITEM_TIMESTAMP
despite parsing it properly. Fix this!

This should make issues like #609 easier to debug.
|
|
The autofs kernel idle logic requires us to poll the kernel for
idleness. This is of course suboptimal, but cannot be fixed without
kernel change.
Currently the polling frequency is set to 1/10 of the idle timeout. This
is quite high, as seen in #571. Let's lower this to 1/3.
