The limitations of readline required that the autocompletion choose
a 'default' device. With multiple phys this doesn't work. Now the
readline limitation has been worked around and station can look up
the device for the command completion.
There is a limitation of libreadline where no context/userdata
can be passed to completion functions. Thi affects iwctl since
the entity value isn't known to completion functions.
Workarounds such as getting the default device are employed but
its not a great solution.
Instead hack around this limitation by parsing the prompt to
extract the entity (second arg). Then use a generic match function
given to readline which can call the actual match function and
include the entity.
The table header needs to be adjusted to include spaces between
columns.
The 'adapter list' command was also updated to shorted a few
columns which were quite long for the data that is actually displayed.
The existing color code escape sequences required the user to set the
color, write the string, then unset with COLOR_OFF. Instead the macros
can be made to take the string itself and automatically terminate the
color with COLOR_OFF. This makes for much more concise strings.
ad-hoc, ap, and wsc all had descriptions longer than the max width but
this is now taken care of automatically. Remove the tab and newline's
from the description.
The WSC pin command description was also changed to be more accurate
since the pin does not need to be 8 digits.
There was no easy to use API for printing the contents of a table, and
was left up to the caller to handle manually. This adds display_table_row
which makes displaying tables much easier, including automatic support
for line truncation and continuation on the next line.
Lines which are too long will be truncated and displayed on the next
line while also taking into account any colored output. This works with any
number of columns.
This removes the need for the module to play games with encoding newlines
and tabs to make the output look nice.
As a start, this functionality was added to the command display.
The generic proxy property display was limited to a width for names/value
which makes the output look nice and uniform, but will cut off any values
which are longer than this limit.
This patch adds some logic to detect this, and continue displaying the
value on the next line.
The width arguments were also updated to be unsigned, which allows checking
the length without a cast.
The dbus proxy code assumes that every interface has a set of
properties registered in a 'proxy_interface_property' structure,
assuming the interface has any properties at all. If the interface
is assumed to have no properties (and no property table) but
actually does, the property table lookup fails but is assumed to
have succeeded and causes a crash.
This caused iwctl to crash after some properties were added to DPP
since the DPP interface previously had no properties.
Now, check that the property table was valid before accessing it. This
should allow properties to be added to new interfaces without crashing
older versions of iwctl.
\e[1;30m is bold black, often, but not always displayed bright black or
bold bright black. In case it is displayed as real black it is
invisible. \e[1;90m is explicit bold bright black.
\e[37m is white, therefore it is not suitable to be labeled as GREY,
which is \e[90m
Two commands were added:
dpp <iface> start-enrollee
dpp <iface> start-configurator
dpp <iface> stop
In addition there is support for using the qrencode utility for displaying
the QR code after DPP is started (enrollee or configurator. If qrencode is
found on the system the QR code will be displayed. Otherwise only the URI
will be printed to the console.
LLD 13 and GNU ld 2.37 support -z start-stop-gc which allows garbage
collection of C identifier name sections despite the __start_/__stop_
references. GNU ld before 2015-10 had the behavior as well. Simply set
the retain attribute so that GCC 11 (if configure-time binutils is 2.36
or newer)/Clang 13 will set the SHF_GNU_RETAIN section attribute to
prevent garbage collection.
Without the patch, there are linker errors with -z start-stop-gc
(LLD default) when -Wl,--gc-sections is used:
```
ld.lld: error: undefined symbol: __start___eap
>>> referenced by eap.c
>>> src/eap.o:(eap_init)
```
The remain attribute will not be needed if the metadata sections are
referenced by code directly.
In non-interactive mode, when a dbus method call returns the process
exits. This is true for all methods except agent requests since e.g.
Connect() call automatically requests credentials and the client must
wait for that to return before exiting. The new daemon interface must
also be treated in the same way and not exit.
When station 'show' is invoked, parse and print any IP addresses
associated with the interface.
If iwd network configuration is disabled and no IP addresses were
configured, print a hint to the user that a DHCP client might need to be
configured.
WEP networks are not supported by iwd. However, the only indication is the
message "Operation not supported" while trying to connect. It is not clear
enough that this is due to intentional lack of support (as opposed to some
kind of misconfiguration). This patch explicitly lists WEP networks shown
with get-networks as unsupported. Hopefully this will make it clearer for
those of us not as familiar with iwd.
This fixes up a previous commit which breaks iwctl. The
check was added to satisfy static analysis but it ended
up preventing iwctl from starting. In this case mkdir
can fail (e.g. if the directory already exists) and only
if it fails should the history be read. Otherwise a
successful mkdir return indicates the history folder is
new and there is no reason to try reading it.
The diagnostic interface will now only come up when station is
connected. This avoids the need for display station to return
a 'connected' out parameter. We can instead just see that
the diagnostic interface doesn't exist.
This will show some basic AP information like Started and
network Name. Some cleanup was done to make the AP interface
and client table columns line up.
StartProfile was added to the AP interface but the required
command was never added to iwctl. This command requires a
profile exists in <configuration dir>/ap/. The syntax is as
follows:
ap <wlanX> start-profile <profile_name>
This command uses GetDiagnostics to show a list of connected
clients and some information about them. The information
contained for each connected station nearly maps 1:1 with the
station diagnostics information shown in "station <wlan> show"
apart from "ConnectedBss" which is now "Address".
For now this module serves as a helper for printing diagnostic
dictionary values. The new API (diagnostic_display) takes a
Dbus iterator which has been entered into a dictionary and
prints out each key and value. A mapping struct was defined
which maps keys to types and units. For simple cases the mapping
will consist of a dbus type character and a units string,
e.g. dBm, Kbit/s etc. For more complex printing which requires
processing the value the 'units' void* cant be set to a
function which can be custom written to handle the value.
