Read wiphy addresses from sysfs and perform the wiphy name to wiphy idx
mapping using sysfs. Do this directly on a new radio notification and
stop using new wiphy notifications except for updating the radio names.
Having the wiphy index available synchronously when parsing a new radio
event we store the wiphy index in the radio_info_rec struct directly and
drop struct wiphy_info_rec as there was a 1:1 mapping. With this, and
knowing that all radio_info data is available when new interface
notifications are received, the tracking is simplified because dbus
objects can be created and destroyed within the notification handlers.
We also now store both the wiphy hardware address data and separately
the interface MAC addresses and can use them more appropriately in the
medium implementation.
Add a daemon mode that is entered when no action was specified on the
command line. In this mode hwsim tracks information on radios through
the netlink events. The interface to make use of the information is
added in the next patch.
Otherwise the EAP-MD5 driver is not found and we get the following
output:
TEST: EAPoL/8021x EAP-TTLS+EAP-MD5 & 4-Way Handshake
Error initializing EAP for ifindex 1
Program received signal SIGSEGV, Segmentation fault.
struct handshake_state is an object that stores all the key data and other
authentication state and does the low level operations on the keys. Together
with the next patch this mostly just splits eapol.c into two layers
so that the key operations can also be used in Fast Transitions which don't
use eapol.
Add rfkill.c/rfkill.h to be used for watching per-wiphy RFkill state.
It uses both /dev/rfkill and /sys because /dev/rfkill is the recommended
way of interfacing with rfkill but at the same time it doesn't provide
the information on mapping to wiphy IDs.
knownnetworks.c/.h implements the KnownNetworks interface and loads the
known networks from storage on startup. The list of all the networks
including information on whether a network is known is managed in
network.c to avoid having two separate lists of network_info structures
and keeping them in sync. That turns out to be difficult because the
network.c list is sorted by connected_time and connected_time changes
can be triggered in both network.c or knownnetworks.c. Both can also
trigger a network_info to be removed completely.
Turn netdev watches into device watches. The intent is to refactor out
netdev specific details into its own class and move device specific
logic into device.c away from wiphy.c
