97be0e87c3 scan: Fix crash 
Sometimes the periodic scan is started and stopped before the timeout
was created.  If periodic_scan_stop was called before, the timeout
object was not reset to NULL, which can lead to a crash.

692bfa23fe wiphy: Sanity check before netdev_disassociated 
The lost beacon event can be received when iwd thinks netdev is
diconnected if it was connected before iwd started, and then
netdev_disassociated will segfault.

a64030069e dbus: Drop unused linux/kdbus.h src/kdbus.c 
Drop the functions that duplicated ell functionality and the now
unneeded kdbus.h copy.
 2016-04-04 14:27:26 -05:00
Andrew Zaborowski
79839dbfd6 dbus: Use native ell kdbus calls 
It seems until now dbus.c would always connect to dbus-1 (unless
DBUS_SESSION_BUS_ADDRESS pointed at kdbus) and passing -K only made
iwd create a kdbus bus and not use it.  Now use ell to actually use
kdbus instead of dbus-1 with -K.  Don't use the src/kdbus.c functions
that duplicate ell functionality.  As a side effect the connection
description and the bloom sizes are now the ell defaults.

14020b2aa6 eapol: Handle EAPoL-EAP packets 2015-11-02 21:45:43 -06:00
Andrew Zaborowski
2bccb7e7dc eapol: Remove user_data from __eapol_rx_packet args 
Instead of passing the user_data parameter in every __eapol_rx_packet
call to be used by EAPOL in all tx_packet calls, add
eapol_sm_set_tx_user_data function that sets the value of user_data for
all subsequent tx_packet calls.  This way tx_packet can be called from
places that are not necessarily inside an __eapol_rx_packet call.

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.

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
was too expensive.

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.
