Commands with non-printable characters were misaligning the labels.
Now these characters are exclude from the labels, and texts are
displayed as a single line.
Under Wayland the GUI doesn't work entirely well (#733).
Setting QT_QPA_PLATFORM to 'xcb' solves some issues, like correctly
positioning popups, but users had to configure it manually.
Now it's possible to configure it from the Preferences dialog.
Setting it to "" will use the default option of the Desktop Environment.
There was a situation where if the ebpf modules path did not exist,
the fw rules were not added, causing the daemon to crash after
connecting to the GUI.
Up until now it when changing the node address, you changed the server
adress as well (i.e: the address where the GUI is listening for
connections).
This simplified configuration when you had 1 node and addresses were
changed at the same time. But in other situations, you were not able to
change the server (GUI) address from the Preferences dialog.
So now:
- the address of each node is changed from the Nodes tab.
- the address of the server (GUI) is changed from the UI tab.
When there were no nodes connected, we disabled the global fw button
that enables/disables the fw.
Unfortunately when a node connected to the GUI, this button was not
clickable anymore.
When disabling the fw, we change the default input and output policy to
Accept, not to block connections.
Due to a problem reloading the fw in the daemon, the policy was not
changed as expected.
This problem must be fixed in the daemon, but for the time being,
sending two configuration changes solves the issue (one for changing the
policy, and another one for disabling the fw).
Closes: #1225
When the Process Connector is used to intercept exec events, get and
build the process tree of a process.
PROCESS CONNECTOR feature was added here: 7a9bb17829
When a popup was displayed to the user, if they took more than 120s to
respond, the address of the node was lost.
This is because the daemon has hardcoded a max timeout of 120s. If it
fires, the call to AskRule is closed and the context is lost.
In this situation, save the address of the node at the start of AskRule,
so we can reuse it later.
Closes: #1219
Nfqueue bypass option skips the enqueue of packets to userspace
if no application is listening to the queue.

If this flag is not specified, and for example the daemon dies
unexpectedly, all the outbound traffic will be blocked.
Up until now we've been using this flag by default not to block network
traffic if the daemon dies or is killed for some reason. But some users
want to use precisely this behaviour (#884, #1183, #1201).
Now you can configure it, to block connections if the daemon
unexpectedly dies.
The option is on by default in the configuration (QueueBypass: true).
If this item is not present in the daemon config file, then it'll be
false.
- Calculate the ram usage of a process in the daemon, using the page
size of the system.
- Added new functions to read some details of a process, so we can use
them in other parts of the code.
Added new task to monitor the resources of remote nodes, like
ram, swap, number of processes or load average of the system.
The task is initiated when the user selects a node, and the data
received from the node is added to the right panel of the Nodes tab.
The task is stopped when changing to another tab, or when deselecting a
node.
Particularly useful for monitoring remote nodes.
