      wcn36xx: Introduce mutual exclusion of fw configuration · 39efc7cc
      Bjorn Andersson authored 
      As the association status changes the driver needs to configure the
hardware. This is done based on information in the "sta" acquired by
ieee80211_find_sta(), which requires the caller to ensure that the "sta"
is valid while its being used; generally by entering an rcu read
section.

But the operations acting on the "sta" has to communicate with the
firmware and may therefor sleep, resulting in the following report:

In order to ensure that the "sta" remains alive (and consistent) for the
duration of bss_info_changed() mutual exclusion has to be ensured with
sta_remove().

This is done by introducing a mutex to cover firmware configuration
changes, which is made to also ensure mutual exclusion between other
operations changing the state or configuration of the firmware. With
this we can drop the rcu read lock.

      ath10k: fix memory leak in rx ring buffer allocation · f35a7f91
      Rakesh Pillai authored 
      The rx ring buffers are added to a hash table if
firmware support full rx reorder. If the full rx
reorder support flag is not set before allocating
the rx ring buffers, none of the buffers are added
to the hash table.

There is a race condition between rx ring refill and
rx buffer replenish from napi poll. The interrupts are
enabled in hif start, before the rx ring is refilled during init.
We replenish buffers from napi poll due to the interrupts which
get enabled after hif start. Hence before the entire rx ring is
refilled during the init, the napi poll replenishes a few buffers
in steps of 100 buffers per attempt. During this rx ring replenish
from napi poll, the rx reorder flag has not been set due to which
the replenished buffers are not added to the hash table

Set the rx full reorder support flag before we allocate
the rx ring buffer to avoid the memory leak.

      Commit a53e35db ("reset: Ensure drivers are explicit when requesting

to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.

      ath10k: push peer type to target for TDLS peers · be5b4f40
      Manikanta Pubbisetty authored 
      WMI interface for all the firmwares(except QCA6174) does not include the
type of peer(default/bss/tdls) requested during peer creation, therefore
target creates a default peer.

TDLS implementation on 10.4 firmware requires host to configure the
peer type(tdls) for TDLS peers. This patch adds peer type parameter to the
existing WMI interface for peer creation to accommodate this requirement.

Tested this change on QCA9888(10.4-3.5.1-00018) and QCA988x(10.2.4.70.9-2)
with ping tests for AP/STA modes.

      ath10k: extend wmi service map to accommodate new services · 810fe818
      Manikanta Pubbisetty authored 
      Though there is room to accommodate 512 services in wmi service
ready event, target uses only first 4-bits of each 32-bit word for
advertising wmi services thereby limiting max wmi services to 64.

TDLS implementation for 10.4 firmwares introduces new wmi services by
making use of remaining unused bits of each 32-bit word, therefore the
wmi service mapping in host needs to be extended.

This patch adds the logic to extend the wmi SVCMAP to accommodate new
wmi services.
