Let's optimize things a bit and properly compare DNS question arrays,
instead of checking if they are mutual supersets. This also makes ANY
query handling more accurate.
It seems that systemd still uses legacy -n option. The option has been
originally designed to avoid write to /etc/mtab during boot when root
FS is not ready or read-only.
This is not necessary for long time, because /etc/mtab is not a real
file (it's symlink) and write to the file is impossible. All utils
should be able to detect the symlink and ignore mtab. This concept is
supported for very long time before systemd.
The userspase mount options are currently maintained by libmount
(mount(8) and mount.nfs) in /run/mount) which is tmpfs initialized
during early boot.
Start-up timestamp of a user instance (userspace_time in struct boot_times)
actually may be arbitrarily big. This, because all timestamps are offset by
that value, leads to creation of arbitrarily wide SVGs which almost completely
consist of blank space.
Fix this by inverse-offsetting all timestamps by that value if user instance
operation is requested.
Fixes#740.
Given three DNS names this function indicates if the second argument lies
strictly between the first and the third according to the canonical DNS
name order. Note that the order is circular, so the last name is
considered to be before the first.
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.
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.
This drops the libsystemd-terminal and systemd-consoled code for various
reasons:
* It's been sitting there unfinished for over a year now and won't get
finished any time soon.
* Since its initial creation, several parts need significant rework: The
input handling should be replaced with the now commonly used libinput,
the drm accessors should coordinate the handling of mode-object
hotplugging (including split connectors) with other DRM users, and the
internal library users should be converted to sd-device and friends.
* There is still significant kernel work required before sd-console is
really useful. This includes, but is not limited to, simpledrm and
drmlog.
* The authority daemon is needed before all this code can be used for
real. And this will definitely take a lot more time to get done as
no-one else is currently working on this, but me.
* kdbus maintenance has taken up way more time than I thought and it has
much higher priority. I don't see me spending much time on the
terminal code in the near future.
If anyone intends to hack on this, please feel free to contact me. I'll
gladly help you out with any issues. Once kdbus and authorityd are
finished (whenever that will be..) I'll definitely pick this up again. But
until then, lets reduce compile times and maintenance efforts on this code
and drop it for now.
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.
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.
