Problem scenario:
1) Host gets roam event from FW and RSO state is switched to
ROAM_IN_PROGRESS.
2) Host gets reassoc response followed by FW down indication.
3) Host processes reassoc response in HDD and sends disassoc to
FW as FW down indication received.
4) As a part of disassoc host tries to switch RSO state to STOP.
But as present RSO state is ROAM_IN_PROGRESS and FW is down,
host fails to send RSO stop command to FW and doesn't switch
RSO state to STOP.
5) Lim disassoc send fails due to FW is down and host proceeds
with lim_send_disassoc_cnf and lim_cleanup_rx_path.
6) In lim_cleanup_rx_path() host checks for present RSO state is
ROAM_IN_PROGRESS and returns without calling lim_del_sta();
7) Thus peer delete and vdev delete is not send to FW and host
vdev State machine stuck at SP-SUSPEND_DOWN which leads to
peer and vdev reference leaks.
Fix:
Allow switch to RSO stop state while present RSO state is
ROAM_IN_PROGRESS.

A race condition can happen when roaming state machine
transition takes place in the following sequence:
1) FW indicates 'roam_synch' event to driver, and driver in
turn, advances its roaming state machine to
'WLAN_ROAM_SYNCH_IN_PROG', in wlan scheduler context;
2) HDD layer starts to do 'disconnect'(could be due to NUD
failure), and thus needs to stop roaming scan offload in
the following sequence:
2.1) Post a RSO stop cmd to FW, via the scheduler thread;
2.2) Advance the roaming state machine to a new state of
'WLAN_ROAM_RSO_STOPPED';
2.3) Check if:
>> the roaming state machine is still in a state of
'WLAN_ROAM_SYNCH_IN_PROG'
>> the neighbor roaming state is in any of the states
below:
eCSR_NEIGHBOR_ROAM_STATE_REASSOCIATING;
eCSR_NEIGHBOR_ROAM_STATE_PREAUTHENTICATING;
eCSR_NEIGHBOR_ROAM_STATE_PREAUTH_DONE;
Here, if any of the conditions becomes true, then
HDD will wait for 4 sec to let the roam_synch handler
finish its job, otherwise the wait will not happen.
2.4) Disconnect the current vdev and advance the roaming
state machine to 'WLAN_ROAM_DEINIT';
In a corner case, race condition can happen in the following
sequence:
>> thread 1), which executes in wlan scheduler context, starts
to run first, and thus roaming state machine advances to
'WLAN_ROAM_SYNCH_IN_PROG', but then gets preempted before
starting to parse the assoc resp frame attached in the
roam_synch event;
>> thread 2) starts to run and posts RSO stop cmd, but the req
msg cannot be handled right away due to scheduler thread
is actively running with other tasks, so it gets queued at
step 2.1);
>> thread 2) continues to run, and simply advances the roaming
state machine to 'WLAN_ROAM_RSO_STOPPED' at 2.2), and then
it will find out none of the conditions listed in 2.3) is
true, so it choses NOT to wait for 'roam_synch' handler to
finish;
>> thread 2) reaches to step 2.4) without waiting at 2.3), and
roaming state machine advances to 'WLAN_ROAM_DEINIT';
>> thread 1) continues to run and starts to parse the assoc
resp frame indicated by FW, and finds that the roaming state
machine NOT in 'WLAN_ROAM_SYNCH_IN_PROG', and thus goes to
the wrong way to treat the buffer in a different manner,
causing a invalid pointer access here.
Fix the racing condition by checking if the roaming state machine
is in 'WLAN_ROAM_SYNCH_IN_PROG' before advancing the same to
'WLAN_ROAM_RSO_STOPPED' in function wlan_hdd_wait_for_roaming().
