Add some of the Device Discovery logic and the DBus API. Device
Discovery is documented as having three states: the Scan Phase, the Find
Phase and the Listen State.
This patch adds the Scan Phase and the next patch adds the Listen State,
which will happen sequentially in a loop until discovery is stopped.
The Find Phase, which is documented as happening at the beginning of the
Discovery Phase, is incorporated into the Scan Phases. The difference
between the two is that Find Phase scans all of the supported channels
while the Scan Phase only scans the three "social" channels. In
practical terms the Find Phase would discover existing groups, which may
operate on any channel, while the Scan Phase will only discover P2P
Devices -- peers that are not in a group yet. To cover existing groups,
we add a few "non-social" channels to each of our active scans
implementing the Scan Phases.
When a new wiphy is added query its regulatory domain and listen for
nl80211 regulatory notifications to be able to provide current
regulatory country code through the new wiphy_get_reg_domain_country().
Implement the Enabled property on device interface. The P2P device is
currently disabled on startup but automatically enabling the P2P device
can be considered.
With the previous commit, wscutil now depends on ie.h. Unfortunately,
wired also includes eap-wsc and wscutil in the build, but not ie, which
results in a link-time failure.
Fix this by droppig eap-wsc and wscutil from wired. There's no reason
that ethernet authentication would ever use the WiFi Protected Setup
authentication.
SOL_NETLINK is used since commit
87a198111a resulting in the following
build failure with glibc < 2.24:
src/frame-xchg.c: In function 'frame_watch_group_io_read':
src/frame-xchg.c:328:27: error: 'SOL_NETLINK' undeclared (first use in this function)
if (cmsg->cmsg_level != SOL_NETLINK)
^
This failure is due to glibc that doesn't support SOL_NETLINK before
version 2.24 and

'Connected' property of the network object is set before the connection
attempt is made and does not indicate a connection success. Therefore,
use device status property to identify the connection status of the device.
The display refresh is automatically enabled or disabled depending on
the width of the window. This allows to avoid the incorrect display on
refresh for the small windows.
Instead of calling display(""), explicitly use the sequence of
commands to force readline to properly update its internal state
and re-display the prompt.
For PSK networks we have netdev.c taking care of setting the linkmode &
operstate. For open adhoc networks, netdev.c was never involved which
resulted in linkmode & operstate never being set. Fix this by invoking
the necessary magic when a connection is established.
adhoc_reset() destroys ssid and sta_states but leaves the pointers
around, athough the adhoc_state structure is not always freed.
This causes a segfault when exiting iwd after a client has done
adhoc start and adhoc stop on a device since adhoc_reset() is called
from adhoc_sta_free although it was previously called from
adhoc_leave_cb().
The netdev_leave_adhoc() returns a negative errno on errors and zero
on success, but adhoc_dbus_stop() assumed the inverse when checking for
an error.
Also, the DBus message was not being referenced in adhoc->pending and
then adhoc_leave_cb() segfaulted attempting to dereference it.
Doing 'ad-hoc <wlan> start_open <"network name">' returned a
"No matching method found" error because start_open called
net.connman.iwd.AdHoc.Start instead of net.connman.iwd.AdHoc.StartOpen.
It seems some APs send the IGTK key in big endian format (it is a
uin16). The kernel rightly reports an -EINVAL error when iwd issues a
NEW_KEY with such a value, resulting in the connection being aborted.
Work around this by trying to detect big-endian key indexes and 'fixing'
them up.
When running test-runner as non-root the environment variables
SUDO_GID/SUDO_UID were unset, causing atoi to segfault. This replaces
atoi with strtol, and checks the existance of SUDO_GID/SUDO_UID
before trying to turn it into an integer. This patch also allows
the uid/gid to be read from the user if running as non-root.
Note: running as non-root does require the users permissions to be
setup properly. Directories and files are created when running with
logging, so if the user running test-runner does not have these
permissions the creation of these files will fail.
