* libertas: fix buffer overrunJohannes Berg2008-10-29
| | | | | | | | | | If somebody sends an invalid beacon/probe response, that can trash the whole BSS descriptor. The descriptor is, luckily, large enough so that it cannot scribble past the end of it; it's well above 400 bytes long.

* | libertas: Reduce the WPA key installation time.Javier Cardona2008-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WPA requires that the PTK is installed immediately after the 4-way handshake in order to properly decrypt the subsequent incoming EAPOL-GTK frame. If the PTK is not enabled by the time the EAPOL-GTK frame arrives, the frame is dropped and the supplicant does not receive the group key. This will happen with fast Access Points that send the EAPOL-GTK frame before the suplicant has successfully installed and enabled the PTK. To mitigate this situation, this patch simplifies and accelerates the SIOCSIWENCODEEXT execution.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes an issus that made "iwconfig eth1 power on" non-working. When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().
