64a70e8c02 qcacld-3.0: Check privilege permission for SET_VAR_INTS_GETNONE
qcacld-2.0 to qcacld-3.0 propagation

Kernel assumes all SET IOCTL commands are assigned with even
numbers. But in our WLAN driver, some SET IOCTLS are assigned with
odd numbers. This leads kernel fail to check, for some SET IOCTLs,
whether user has the right permission to do SET operation.
Hence, in driver, before processing SET_VAR_INTS_GETNONE, making
sure user task has right permission to process the command.

b315218e7a qcacld-3.0: Handle excessive logging during hostap select queue
qcacld-2.0 to qcacld-3.0 propagation

As a part of unload hdd is stopping the netdev queue.
But still N/W layer 3 is calling the select queue netdev
ops, where error print for sap context is Null appears
excessively.
As a part of this fix hostap select queue need to validate
Hdd context to take care of SSR and load / unload cases.

10a00267d0 qcacld-3.0:IBSS:Update HT secondary channel offset from beacon in pStaDs
qcacld-2.0 to qcacld-3.0 propagation

While adding pStaDs for IBSS when peer beacon is received, HT
secondary channel offset is not copied from beacon. This leads to
false change capability indication while processing the same beacon
and thus update cb mode is sent with staid 255(default),
leading to crash.

Update HT secondary channel offset from beacon and add a check in
cbmode update to ignore update if staid is 255.

b0319c4725 qcacld-3.0: synchronize concurrent access of shared variable
qcacld-2.0 to qcacld-3.0 propagation

Currently DFS variables are accessed in different context without
protection leading to NULL pointer dereferences.

Ensure lock is taken before accessing the DFS shared variable.

e3eaebe339 qcacld-3.0: Do not update WLAN status to LPASS when disconnect during unload
qcacld-2.0 to qcacld-3.0 propagation

Host driver updates WLAN status to LPASS with connected false and WLAN on
when disconnection happens. Host driver also updates WLAN status right
after driver unload is triggered with connected false and WLAN off. There
is a scenario that disconnection callback comes during driver unloading
which causes LPASS misbehavior. Fix this by only updating disconnection
status to LAPSS when driver is not unloading.

4ea4f05710 qcacld-3.0: Increase SSR timeout to 30 seconds
qcacld-2.0 to qcacld-3.0 propagation

Increase SSR timeout from 15 seconds to 30 seconds in order to handle
some corner cases which may cause SSR to take longer time. E.g. CPU is
busy/stuck with other tasks.

recovery during suspend.

If self-recovery is enabled in ini file, recover if host driver fails to
receive HTC ACK from FW for PDEV suspend, otherwise do VOS_BUG.

cd9614433f qcacld-3.0: Fix several SSR related issues
qcacld-2.0 to qcacld-3.0 propagation

- Kill wlan_tasklet before freeing TLshim free queue. This can avoid
  race condition between SSR and wlan_tasklet which is still processing
  Rx packets in the case of self-recovery when FW doesn't really crash.

- In additional to connected state, add disconnected/disconnecting states
  to send notification to supplicant for re-issuing connect after SSR.
  This is to avoid corner cases that while FW crashes, disconnection is
  happening or disconnection fails because of FW crash, the HDD state is
  changed from connected to disconnecting/disconnected.
