00cafb2cc5 wiphy: Check early that a BSS supports compatible ciphers. 
In the D-bus .Connect call return an error immediately if we
find that there's no common cipher supported between iwd, the
network adapter and the AP.  This is to avoid asking the agent
for the passkey if we know the connection will fail.

An alternative would be to only show networks that we can connect
to in the scan results on D-bus but I suspect that would cause
more pain to users debugging their wifi setups on average.

For now, if a passphrase is needed we check once before querying
for passphrase and recheck afterwards when we're about to
associate.

should always be 0.  Thus it is safe to drop the !is_wpa condition.

handshake.

This patch saves off the PSK generated based on the passphrase provided

successful.

Subsequent connection attempts to the known AP use the PSK saved on the
filesystem (default /var/lib/iwd/<ssid>.psk).  If the connection fails,
the agent will again be asked for the passphrase on the next attempt.

We will ignore non-UTF8 based SSIDs.  Support for non-UTF8 SSIDs seems
to be of dubious value in the real world as the vast majority of
consumer devices would not even allow such SSIDs to be configured or
used.

There also seems to be no compelling argument to support such SSIDs, so
until that argument arrives, non-UTF8 SSIDs will be filtered out.  This
makes the D-Bus API and implementation much easier.

9c1780c0a1 wiphy: Use dbus object path as network key in hash 
Modifying a bit how networks are stored inside the hashtable:
1 - instead of the network id, the network's object path is used
2 - network holds the pointer of the object path
3 - the hashtable does not free the key (network_free() will)

This permits to optimize on:
1 - one memory allocation used for 2 distinct things
2 - remove the need to re-compute the object path (and the id) when it's
needed, it can use dircetly the one stored in the network structure.

Open networks do not contain a RSN element, so storing a 256 byte buffer

This patch also has the side-effect of fixing detection of Open
Networks.  Prior to this, if the scan results did not contain an RSN IE,
the 'rsne' variable would be set to all zeros.  scan_get_ssid_security
would then be called, but instead of a NULL struct ie_rsn_info, a
non-null, but zerod out ie_rsn_info would be passed in.  This caused the
code to work, but for the wrong reasons.

d0cb0aedc6 wiphy: Check return value when appending attributes 
Make sure to print some errors if attributes cannot be appended
to a message. It is dangerous to ignore the return code from
l_genl_msg_append_attr() because the kernel might act weirdly
if some attribute is missing.

fcda15c587 wiphy: Scheduled scan startup message was too short

672be730c3 wiphy: Add scheduled scan support 
Add rudimentary support for mac80211 scheduled scan feature.
This is done so that kernel support for task called "Bind
NL80211_CMD_START_SCHED_SCAN to netlink socket" from TODO
file can be tested. The current scan interval is set to 60
seconds which is probably too fast for the final version.

051f49ea85 wiphy: Tweak netdev structure creation order 
Because none of the attributes are assigned until after the DeviceAdded
signal is emitted, the signal appears with invalid properties.  For now,
move the netdev structure fill-out into the if statement.

If the netdev attributes can change, then these need to be handled
separately and appropriate signals to be sent.
