028e7243ac wl18xx: move to new firmware (wl18xx-fw-3.bin)
Bump the min wl18xx fw version to 8.8.0.0.13

This fw is not backward compatible with older
firmware (due to api changes), so use bump
the firmware name as well.

Some modifications were done to the driver-fw api
in order to support multiple APs.

Additionally, some of the consts (such as max stations,
max links and max RX BA sessions) were changed.

abf0b24912 wlcore/wl12xx/wl18xx: configure iface_combinations per-hw
Each hw supports a different iface combinations.
Define the supported combinations in each driver,
and save it in wl->iface_combinations.

Since each driver defines its own combinations now,
it can also define its max supported channels, so
we no longer need to save and set it explicitly
in wlcore.

Update wl18xx interface combinations to allow
multiple APs.

da08fdfaf0 wlcore/wl12xx/wl18xx: configure num_links per-hw
Upcoming fw versions will have different max links support
(according to the hw). Get ready for it by configuring
wl->num_links per-hw, instead of using the const WL12XX_MAX_LINKS.

However, continue using WLCORE_MAX_LINKS in order to simplify
structs declarations (we use it in multiple bitmaps, and converting
them to dynamic arrays is just cumbersome).

75fb4df7f8 wlcore/wl12xx/wl18xx: simplify fw_status handling
Instead of splitting the fw_status into 2 and using some
complex calculations, read the fw status and let each low-level
driver (wl12xx/wl18xx) convert it into a common struct.

This is required for the upcoming fw api changes, which
break the current logic anyway.

7a536265b0 wlcore: AP: don't start mac80211 PS on non-peer HLIDs
It seems the wl18xx FW sometimes sends spurious changes on the PSM state
of the broadcast HLID. This causes us to search for a station on a
non-peer link and fail, causing warnings in our log.

Prevent the driver from considering PSM changes for any non-peer HLIDs.

9be86cf067 wlcore: cancel Tx watchdog on suspend and rearm on first Tx after
Sometimes a tx_flush during suspend fails, but the FW manages to flush
out the packets during the time when the host is supsended. Cancel
the Tx-watchdog on suspend to not cause a spurious recovery on resume
for that case. Set a flag to reinit the watchdog on the first Tx after
resume, so we'll still recover if the FW is not empty and there's
indeed a problem.

The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

64322e28d3 wl1251: fix scan behaviour while not associated
With a dissasociated card I often encoutered very long scan delays.

My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.

Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

Old userspace sending either flag will have it treated as

Newer userspace will have to be aware of older kernels.

1fb9026000 mac80211: move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into drivers
mac80211 currently sets WIPHY_FLAG_SUPPORTS_SCHED_SCAN based on whether
the start_sched_scan operation is supported or not, but that will not
be correct for all drivers, we're adding scheduled scan to the iwlmvm
driver but it depends on firmware support.

Therefore, move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into the drivers
so that they can control it regardless of implementing the operation.

This currently only affects the TI drivers since they're the only ones
implementing scheduled scan (in a mac80211 driver.)

496322bc91 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller:
 "This is a re-do of the net-next pull request for the current merge
  window.  The only difference from the one I made the other day is that
  this has Eliezer's interface renames and the timeout handling changes
  made based upon your feedback, as well as a few bug fixes that have
  trickeled in.

  Highlights:

   1) Low latency device polling, eliminating the cost of interrupt
      handling and context switches.  Allows direct polling of a network
      device from socket operations, such as recvmsg() and poll().

      Currently ixgbe, mlx4, and bnx2x support this feature.

      Full high level description, performance numbers, and design in
      commit 0a4db187a9 ("Merge branch 'll_poll'")

      From Eliezer Tamir.

   2) With the routing cache removed, ip_check_mc_rcu() gets exercised
      more than ever before in the case where we have lots of multicast
      addresses.  Use a hash table instead of a simple linked list, from
      Eric Dumazet.

   3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
      Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
      Marek Puzyniak, Michal Kazior, and Sujith Manoharan.

   4) Support reporting the TUN device persist flag to userspace, from
      Pavel Emelyanov.

   5) Allow controlling network device VF link state using netlink, from
      Rony Efraim.

   6) Support GRE tunneling in openvswitch, from Pravin B Shelar.

   7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
      Daniel Borkmann and Eric Dumazet.

   8) Allow controlling of TCP quickack behavior on a per-route basis,
      from Cong Wang.

   9) Several bug fixes and improvements to vxlan from Stephen
      Hemminger, Pravin B Shelar, and Mike Rapoport.  In particular,
      support receiving on multiple UDP ports.

  10) Major cleanups, particular in the area of debugging and cookie
      lifetime handline, to the SCTP protocol code.  From Daniel
      Borkmann.

  11) Allow packets to cross network namespaces when traversing tunnel
      devices.  From Nicolas Dichtel.

  12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
      manner akin to how we monitor real network traffic via ptype_all.
      From Daniel Borkmann.

  13) Several bug fixes and improvements for the new alx device driver,
      from Johannes Berg.

  14) Fix scalability issues in the netem packet scheduler's time queue,
      by using an rbtree.  From Eric Dumazet.

  15) Several bug fixes in TCP loss recovery handling, from Yuchung
      Cheng.

  16) Add support for GSO segmentation of MPLS packets, from Simon
      Horman.

  17) Make network notifiers have a real data type for the opaque
      pointer that's passed into them.  Use this to properly handle
      network device flag changes in arp_netdev_event().  From Jiri
      Pirko and Timo Teräs.

  18) Convert several drivers over to module_pci_driver(), from Peter
      Huewe.

  19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
      O(1) calculation instead.  From Eric Dumazet.

  20) Support setting of explicit tunnel peer addresses in ipv6, just
      like ipv4.  From Nicolas Dichtel.

  21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.

  22) Prevent a single high rate flow from overruning an individual cpu
      during RX packet processing via selective flow shedding.  From
      Willem de Bruijn.

  23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
      Dumazet.

  24) Don't just drop GSO packets which are above the TBF scheduler's
      burst limit, chop them up so they are in-bounds instead.  Also
      from Eric Dumazet.

  25) VLAN offloads are missed when configured on top of a bridge, fix
      from Vlad Yasevich.

  26) Support IPV6 in ping sockets.  From Lorenzo Colitti.

  27) Receive flow steering targets should be updated at poll() time
      too, from David Majnemer.

  28) Fix several corner case regressions in PMTU/redirect handling due
      to the routing cache removal, from Timo Teräs.

  29) We have to be mindful of ipv4 mapped ipv6 sockets in
      upd_v6_push_pending_frames().  From Hannes Frederic Sowa.

  30) Fix L2TP sequence number handling bugs, from James Chapman."

5cbba2d48a wlcore: fix occasional AP TX stop after recovery
The fw_status wasn't zeroed during allocation, resulting
in uninitialized var usage, and finally causing AP
traffic stop after recovery.

The wrong value in fw_status_2->counters.tx_lnk_free_pkts
led to a bad lnk->allocated_pkts calculation in
wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return
FALSE (lnk->allocated_pkts > thold).
This eventually blocked the link in wlcore_tx_work_locked(),
as wl1271_skb_dequeue() continuously returned NULL.

e3b8bbb9e8 wl18xx: FDSP Code RAM Corruption fix
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.

PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).

This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.

The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.

The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:

1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

For this to work it is also necessary to convert everything

the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware

93d5d10085 wlcore: consolidate tx_seq handling on recovery
Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.

This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.

A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.

When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.

This functionality is STA only currently.

e1a0c6b3a4 mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40
For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

18b559d5db mac80211: split TX aggregation stop action
When TX aggregation is stopped, there are a few
different cases:
 - connection with the peer was dropped
 - session stop was requested locally
 - session stop was requested by the peer
 - connection was dropped while a session is stopping

The behaviour in these cases should be different, if
the connection is dropped then the driver should drop
all frames, otherwise the frames may continue to be
transmitted, aggregated in the case of a locally
requested session stop or unaggregated in the case of
the peer requesting session stop.

Split these different cases so that the driver can
act accordingly; however, treat local and remote stop
the same way and ask the driver to not send frames as
aggregated packets any more.

In the case of connection drop, the stop callback the
driver is otherwise supposed to call is no longer
required.

1c33db782d wlcore: use separate HW queue for each AC in each vif
Start using the new hw_queue mechanism in mac80211 and give each AC in
each vif its own hw_queue number. This allows us to stop an AC in a vif
independently from other vifs.

Change the Tx watermark handling functions to count packets per AC in
vif. From now on fast links should not be able to hurt the throughput
of slow links on the same AC but on different vifs.

Change internal queue mgmt functions to operate per vif, to support the
new Tx watermark granularity. Make the global versions of the queue
stop/start functions to use the global mac80211 API for queue mgmt. This
helps in situations where the driver currently doesn't know all the vifs
that reside in mac80211. Recovery is a good example for such a case.

For 18xx the changes are:

- Active links now get their thresholds directly from FW
- There's a new "stop" threshold for active links, at which point a link
  stops receiving new packets.

0e81047996 wlcore: improved Tx scheduling algorithm
Prioritize EDCA by choosing the AC before anything else. Use the
fast/slow link bitmap in FW to improve the scheduling algorithm for
the multi-link scenario.

Set packet thresholds to determine if a given link is high or low
priority according to its speed. A slow link will be given high priority
if the amount of packets queued for it in the FW is lower than the
slow-threshold. Similarly, a fast link will be given high priority if
the number of its packets queued in FW is smaller than the high-threshold.

The improved algorithm:
1. Choose optimal AC according to FW utilization
2. Traversing the VIFs in a round-robin fashion, try to choose a high
   priority link. Links are traversed in a round-robin fashion inside a
   VIF.
3. If no high priority links are found, choose the first non-empty
   (low priority) link found in the round robin.

The firmwares version string contain 5 integers.  We used to consider
all the digits (except for the first one, which indicates the chip) as
linearly increasing version numbers.  This is not correct, because
some of the integers indicate type of firmware (eg. single-role
vs. multi-role) or the internal project it was created for.

Besides, this varies a bit from chip to chip, so we need to make the
firmware version checks more flexible (eg. allow the lower driver to
ignore some of the integers).  Additionally, we need to change the
code so that we only check for a linearly increasing number on the
fields where this actually makes sense.

c108c90535 wlcore: gather information about firmware stability
It's sometimes useful to gather information about the firmware
stability in long test runs, especially to see if problems are
recurring frequently or not.  With this commit we count the number of
times a hardware recovery was issued and print it out during recovery
and in the driver_state in debugfs.

6b70e7eb70 wlcore: add new reg-domain configuration command
In 18xx the calibration process of the PHY Cortex domain
requires to perform an active calibration of the channel
before it can be used for transmission. To fulfill world
wide regulatory restrictions, fw should be always
synchronized/updated with current CRDA configuration.
Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the
fw with current reg-domain, this command passes a bit map
of channels that are allowed to be used for transmission.

The driver shall update the fw during initialization and
after each change in the current reg-domain
configuration. The driver will save the channel number of
incoming beacons during the scan process, as they might
be a result of the passive scan on
"IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the
fw accordingly once the scan is finished, the purpose of
this is to be ready in case of the authentication request
on one of these disabled (uncalibrated) channels.

The new command requires to wait for the fw completion
event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT".

No scan commands (including the sched scan) can be
executed concurrently with the "CMD_DFS_CHANNEL_CONFIG",
wl->mutex ensures that.

Make it simpler by starting sta role on bssid change,

* Split wl1271_join() into wlcore_join (tuning on
  a channel/bssid) and wlcore_set_assoc (configure
  sta after association).
* Rename wl1271_unjoin() to wlcore_unset_assoc(), as
  it is no longer the inversion of wl1271_join()
  (now it's only used to disconnect associated sta /
  joined ibss, without stopping the role).
* Set ssid before starting station role (needed for
  start_role(sta)

While on it, split wl1271_bss_info_changed_sta() into

call in wl12xx_chip_wakeup, the containing function just returns, but on
the failure of the call in wl12xx_get_hw_info, the containing function
calls wl1271_power_off.  This does not seem necessary, because if
wl12xx_set_power_on has set the power on and then fails, it has already
turned the power off.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

8b2c98243e mac80211: clarify interface iteration and make it configurable
During hardware restart, all interfaces are iterated even
though they haven't been re-added to the driver, document
this behaviour. The same also happens during resume, which
is even more confusing since all of the interfaces were
previously removed from the driver. Make this optional so
drivers relying on the current behaviour can still use it,
but to let drivers that don't want this behaviour disable
it.

Also convert all API users, keeping the old semantics
except in hwsim, where the new normal ones are desired.

af390f4dd3 wlcore: protect wlcore_op_set_key with mutex
wlcore_op_set_key() calls wl18xx_set_key(),
which in turn executes some of his function
calls without acquiring wl->mutex and making
sure the fw is awake.

Adding mutex_lock()/ps_elp_wakeup() calls is
not enough, as wl18xx_set_key() calls
wl1271_tx_flush() which can't be called while
the mutex is taken.

Add the required calls to wlcore_op_set_key,
but limit the queues_stop and flushing
to the only encryption types in which
a spare block might be needed (GEM and TKIP).

ab2c4f37dc wlcore: decrease elp timeout
The current elp timeout (the same as the dynamic
ps timeout - 1500ms) is too high. Usually,
wl1271_ps_elp_sleep() get called right after tx/rx,
which is fine, but some command might get sent
even when there is no traffic (e.g. ht changes
triggered by beacon frames), and leaving the
device awake for 1500ms in this case is redundant.

Use a timeout of 30ms.
The fw won't enter elp anyway before the dynamic-ps
timeout was expired as well (and it entered ps
successfully).

Previously, invalidation of the keep-alive template was
done when going idle. However, while removing the
idle-handling we didn't move the keep-alive template
invalidation to another place.

This finally resulted in fw error when trying to use

(Note that we still have an error here - each role
should have its unique keep-alive template id, while
currently they all use CMD_TEMPL_KLV_IDX_NULL_DATA (0).
This only works now because we don't support concurrent
