This will help to get rid of magic number use throughout the project.
The definitions should be limited to global magic numbers that are used
throughout the project, for example SSID length, MAC address length,
etc.
Due to an unnoticed bug after adding the BasicServiceSet object into
network, it became clear that since station already owns the scan_bss
objects it makes sense for it to manage the associated DBus objects
as well. This way network doesn't have to jump through hoops to
determine if the scan_bss object was remove, added, or updated. It
can just manage its list as it did prior.
From the station side this makes things very easy. When scan results
come in we either update or add a new DBus object. And any time a
scan_bss is freed we remove the DBus object.
To reduce code duplication and prepare for moving the BSS interface
to station, add a new API so station can create a BSS path without
a network object directly.
src/eapol.c:1041:9: error: ‘buf’ may be used uninitialized [-Werror=maybe-uninitialized]
1041 | l_put_be16(0, &frame->header.packet_len);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This warning is bogus since the buffer is initialized through use of
eapol_frame members. EAPoL-Start is a very simple frame.
This was seemingly trivial at face value but doing so ended up
pointing out a bug with how group_retry is set when forcing
the default group. Since group_retry is initialized to -1 the
increment in the force_default_group block results in it being
set to zero, which is actually group 20, not 19. This did not
matter for hunt and peck, but H2E actually uses the retry value
to index its pre-generated points which then breaks SAE if
forcing the default group with H2E.
To handle H2E and force_default_group, the group selection
logic will always begin iterating the group array regardless of
SAE type.
The property itself is an array of paths, but this is difficult
to fit nicely within a terminal. Instead just display the count
of BSS's. Displaying a detailed list of BSS's will be done via
a separate command.
There are certain cases where we may not want to display the entire
header for a given set of properties. For example displaying a list
of proxy interfaces. Add finer control by separating out the header
and the prop/value display into two functions.
This will tell network the BSS list is being updated and it can
act accordingly as far as the BSS DBus registrations/unregistration.
In addition any scan_bss object needing to be freed has to wait
until after network_bss_stop_update() because network has to be able
to iterate its old list and unregister any BSS's that were not seen
in the scan results. This is done by pushing each BSS needing to be
freed into a queue, then destroying them after the BSS's are all
added.
This adds a new DBus object/interface for tracking BSS's for
a given network. Since scanning replaces scan_bss objects some
new APIs were added to avoid tearing down the associated DBus
object for each BSS.
network_bss_start_update() should be called before any new BSS's
are added to the network object. This will keep track of the old
list and create a new network->bss_list where more entries can
be added. This is effectively replacing network_bss_list_clear,
except it keeps the old list around until...
network_bss_stop_update() is called when all BSS's have been
added to the network object. This will then iterate the old list
and lookup if any BSS DBus objects need to be destroyed. Once
completed the old list is destroyed.
iwd supports FILS only on softmac drivers. Ensure the capability check
is consistent between wiphy and netdev, both the softmac and the
relevant EXT_FEATURE bit must be checked.
CMD_EXTERNAL_AUTH could potentially be used for FILS for FullMAC cards,
but no hardware supporting this has been identified yet.
Somehow this ability was lost in the refactoring. OWE was intended to
be used on fullmac cards, but the state machine is only actually created
if the connection type ends up being softmac.
Fixes: 8b6ad5d3b9 ("owe: netdev: refactor to remove OWE as an auth-proto")
Certain flags (for example, NLA_F_NESTED) are ORed with the netlink
attribute type identifier prior to being sent on the wire. Such flags
need to be masked off and not taken into consideration when attribute
type is being compared against known values.
The workaround for Cisco APs reporting an operating class of zero
is still a bug that remains in Cisco equipment. This is made even
worse with the introduction of 6GHz where the channel numbers
overlap with both 2.4 and 5GHz bands. This makes it impossible to
definitively choose a frequency given only a channel number.
To improve this workaround and cover the 6GHz band we can calculate
a frequency for each band and see what is successful. Then append
each frequency we get to the list. This will result in more
frequencies scanned, but this tradeoff is better than potentially
avoiding a roam to 6GHz or high order 5ghz channel numbers.

QEMU now seems to complain that 'no-hpet' and 'no-acpi' command line
arguments are unrecognized.
l_genl class has nice ways of discovering and requesting families. The
genl functionality has been added after the iwmon skeleton was created,
but it is now time to migrate to using these APIs.
This attribute is actually an array of signed 32 bit integers and it
was being treated as a single integer. This would work until more
than one threshold was set, then it would fail to parse it.
After the station state changes in DPP setting autoconnect=True was
causing DPP to stop prior to being able to scan for the network.
Instead we can start autoconnect earlier so we aren't toggling the
property while DPP is running.
