Save the value of the watchlist pointer at the beginning of the
WATCHLIST_NOTIFY_* macros as if it was a function. This will fix a
frame-xchg.c scenario in which one of the watch callback removes the
frame watch group and the memory where the watchlist pointer was
becomes unallocated but the macro still needs to access it ones or
twice while it destroys the watchlist. Another option would be for
the pointer to be copied in frame-xchg.c itself.
Use netconfig.c functions to unconditionally run DHCP negotiation,
fail the connection setup if DHCP fails. Only report connection success
after netconfig returns.
Add the final two steps of the connection setup, and corresponding
disconnect logic:
* the WSC connection to the GO to do the client provisioning,
* the netdev_connect call to use the provisioned credentials for the
final WPA2 connection.
Once we've found the provisioning BSS create the P2P-Client interface
that we're going to use for the actual provisioning and the final P2P
connection.
Some devices (a Wi-Fi Display dongle in my case) will send us Probe
Requests and wait for a response before they send us the GO
Negotiation Request that we're waiting for after the peer initially
replied with "Fail: Information Not Available" to our GO Negotiation
attempt. Curiously this specific device I tested would even accept
a Probe Response with a mangled body such that the IE sequence couldn't
be parsed.
Handle the scenario where the peer's P2P state machine doesn't know
whether a connection has been authorized by the user and needs some time
to ask the user or a higher software layer whether to accept a
connection. In that case their GO Negotiation Response to our GO
Negotiation Request will have the status code "Fail: Information Not
Available" and we need to give the peer 120s to start a new GO
Negotiation with us. In this patch we handle the GO Negotiation
responder side where we parse the Request frame, build and send the
Response and finally parse the Confirmation. The existing code so far
only did the initiator side.
Parse the GO Negotiation Response frame and if no errors found send the
GO Negotiation Confirmation. If that gets ACKed wait for the GO to set
up the group.
Add net.connman.iwd.SimpleConfiguration interfaces to peer objects on
DBus and handle method calls. Building and transmitting the actual
action frames to start the connection sequence is done in the following
commits.
For wired authentication the protocol version used in the EAPOL
packets sent by ead is fixed to 802.1X-2004 (2) but some switches
implementing only 802.1X-2001 erroneously ignore these packets.
As ead only sends EAPOL-Start and EAP-Packet packets and these have
not changed between 802.1X-2001 and 802.1X-2004 there should be
no reason to use 802.1X-2004. Hence, this changes ead to always use
802.1X-2001 (1) instead.
Switches implementing newer versions of 802.1X should not have
problems responding to packets using the original version.
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.
