Vamsi Krishna b4a41abad4 nl80211: Do not ignore disconnection event after a connection event 
After a disconnect command is issued, wpa_supplicant generates a
disconnection event to self and ignores the next disconnection event
coming from the driver.  In a race condition in which the driver
generates a connected event due to roaming just before receiving the
disconnect command from userspace, wpa_supplicant processes the
connected event after processing the self-generated disconnection event
and enters WPA_COMPLETED state. The driver sends a disconnection event
after processing the disconnect command sent by wpa_supplicant but the
disconnection event is ignored by wpa_supplicant as the disconnection
event is considered to be a result of locally generated disconnect
command. Thus, wpa_supplicant continues to be in the connected
(WPA_COMPLETED) state though the driver is in disconnected state.

Fix this out-of-sync behavior between the driver and wpa_supplicant by
not ignoring the disconnection event from the driver because of the
locally generated disconnect command sent to the driver if there is a
connection event received after issuing the disconnect command to the
driver.

file for more instructions.


This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.

Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
