32e9947e66 ath11k: Use host CE parameters for CE interrupts configuration
[ Upstream commit b689f091aa ]

CE interrupt configuration uses host ce parameters to assign/free
interrupts. Use host ce parameters to enable/disable interrupts.
This patch fixes below BUG,

BUG: KASAN: global-out-of-bounds in 0xffffffbffdfb035c at addr
ffffffbffde6eeac
 Read of size 4 by task kworker/u8:2/132
 Address belongs to variable ath11k_core_qmi_firmware_ready+0x1b0/0x5bc [ath11k]

OOB is due to ath11k_ahb_ce_irqs_enable() iterates ce_count(which is 12)
times and accessing 12th element in target_ce_config
(which has only 11 elements) from ath11k_ahb_ce_irq_enable().

With this change host ce configs are used to enable/disable interrupts.

6a49acfaca crypto: qat - fix undetected PFVF timeout in ACK loop
[ Upstream commit 5002200b4f ]

If the remote function did not ACK the reception of a message, the
function __adf_iov_putmsg() could detect it as a collision.

This was due to the fact that the collision and the timeout checks after
the ACK loop were in the wrong order. The timeout must be checked at the
end of the loop, so fix by swapping the order of the two checks.

475ac5c565 crypto: qat - make pfvf send message direction agnostic
[ Upstream commit 6e680f94bc ]

The functions adf_iov_putmsg() and __adf_iov_putmsg() are shared by both
PF and VF. Any logging or documentation should not refer to any specific
direction.

Make comments and log messages direction agnostic by replacing PF2VF
with PFVF. Also fix the wording for some related comments.

ee1c74c3c9 crypto: qat - remove unnecessary collision prevention step in PFVF
[ Upstream commit e17f49bb24 ]

The initial version of the PFVF protocol included an initial "carrier
sensing" to get ownership of the channel.

Collisions can happen anyway, the extra wait and test does not prevent
collisions, it instead slows the communication down, so remove it.

The CAT875 sub board from Silicon Linux uses a Realtek PHY.

The phy driver commit bbc4d71d63 ("net: phy: realtek: fix

needs both rx/tx delays for the NFS mount to work.

This patch fixes the NFS mount failure issue by adding "rgmii-id" mode
to the avb device node.

This patch will surround the AF_INET6 case in sk_error_report() of dlm
with a #if IS_ENABLED(CONFIG_IPV6). The field sk->sk_v6_daddr is not
defined when CONFIG_IPV6 is disabled. If CONFIG_IPV6 is disabled, the
socket creation with AF_INET6 should already fail because a runtime
check if AF_INET6 is registered. However if there is the possibility
that AF_INET6 is set as sk_family the sk_error_report() callback will
print then an invalid family type error.

097e601eb8 ath11k: reset RSN/WPA present state for open BSS
[ Upstream commit 64bc3aa02a ]

The ath11k driver is caching the information about RSN/WPA IE in the
configured beacon template. The cached information is used during
associations to figure out whether 4-way PKT/2-way GTK peer flags need to
be set or not.

But the code never cleared the state when no such IE was found. This can
for example happen when moving from an WPA/RSN to an open setup. The
(seemingly connected) peer was then not able to communicate over the
link because the firmware assumed a different (encryption enabled) state
for the peer.

df94b37e90 ath11k: Fix ETSI regd with weather radar overlap
[ Upstream commit 086c921a35 ]

Some ETSI countries have a small overlap in the wireless-regdb with an ETSI
channel (5590-5650). A good example is Australia:

  country AU: DFS-ETSI
  	(2400 - 2483.5 @ 40), (36)
  	(5150 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW
  	(5250 - 5350 @ 80), (20), NO-OUTDOOR, AUTO-BW, DFS
  	(5470 - 5600 @ 80), (27), DFS
  	(5650 - 5730 @ 80), (27), DFS
  	(5730 - 5850 @ 80), (36)
  	(57000 - 66000 @ 2160), (43), NO-OUTDOOR

If the firmware (or the BDF) is shipped with these rules then there is only
a 10 MHz overlap with the weather radar:

* below: 5470 - 5590
* weather radar: 5590 - 5600
* above: (none for the rule "5470 - 5600 @ 80")

There are several wrong assumption in the ath11k code:

* there is always a valid range below the weather radar
  (actually: there could be no range below the weather radar range OR range
   could be smaller than 20 MHz)
* intersected range in the weather radar range is valid
  (actually: the range could be smaller than 20 MHz)
* range above weather radar is either empty or valid
  (actually: the range could be smaller than 20 MHz)

These wrong assumption will lead in this example to a rule

  (5590 - 5600 @ 20), (N/A, 27), (600000 ms), DFS, AUTO-BW

which is invalid according to is_valid_reg_rule() because the freq_diff is
only 10 MHz but the max_bandwidth is set to 20 MHz. Which results in a
rejection like:

  ath11k c000000.wifi: failed to perform regd update : -22
  Invalid regulatory domain detected

To avoid this, the algorithm has to be changed slightly. Instead of
splitting a rule which overlaps with the weather radar range into 3 pieces
and accepting the first two parts blindly, it must actually be checked for
each piece whether it is a valid range. And only if it is valid, add it to
the output array.

When these checks are in place, the processed rules for AU would end up as

  country AU: DFS-ETSI
          (2400 - 2483 @ 40), (N/A, 36), (N/A)
          (5150 - 5250 @ 80), (6, 23), (N/A), NO-OUTDOOR, AUTO-BW
          (5250 - 5350 @ 80), (6, 20), (0 ms), NO-OUTDOOR, DFS, AUTO-BW

ffc9019bd9 Bluetooth: stop proccessing malicious adv data
[ Upstream commit 3a56ef719f ]

Syzbot reported slab-out-of-bounds read in hci_le_adv_report_evt(). The
problem was in missing validaion check.

We should check if data is not malicious and we can read next data block.
If we won't check ptr validness, code can read a way beyond skb->end and
it can cause problems, of course.

55917db359 fs: dlm: don't call kernel_getpeername() in error_report()
[ Upstream commit 4c3d90570b ]

In some cases kernel_getpeername() will held the socket lock which is
already held when the socket layer calls error_report() callback. Since
commit 9dfc685e02 ("inet: remove races in inet{6}_getname()") this
problem becomes more likely because the socket lock will be held always.

It is and was always forbidden to call kernel_getpeername() in context
of error_report(). To get rid of the problem we access the destination

print out the destination port of the inet socket.

0b57480ed5 media: aspeed: Update signal status immediately to ensure sane hw state
[ Upstream commit af6d1bde39 ]

If res-chg, VE_INTERRUPT_MODE_DETECT_WD irq will be raised. But
v4l2_input_status won't be updated to no-signal immediately until
aspeed_video_get_resolution() in aspeed_video_resolution_work().

During the period of time, aspeed_video_start_frame() could be called
because it doesn't know signal becomes unstable now. If it goes with
aspeed_video_init_regs() of aspeed_video_irq_res_change()
simultaneously, it will mess up hw state.

To fix this problem, v4l2_input_status is updated to no-signal
immediately for VE_INTERRUPT_MODE_DETECT_WD irq.

22b0b68f7d media: atomisp: fix ifdefs in sh_css.c
[ Upstream commit 5a1b272555 ]

 ## `if (pipe->stream->config.mode == IA_CSS_INPUT_MODE_TPG) {` case

The intel-aero atomisp has `#if defined(IS_ISP_2400_SYSTEM)` [1]. It is
to be defined in the following two places [2]:

  - css/hive_isp_css_common/system_global.h
  - css/css_2401_csi2p_system/system_global.h

and the former file is to be included on ISP2400 devices, too. So, it
is to be defined for both ISP2400 and ISP2401 devices.

Because the upstreamed atomisp driver now supports only ISP2400 and
ISP2401, just remove the ISP version test again. This matches the other
upstream commits like 3c0538fbad ("media: atomisp: get rid of most
checks for ISP2401 version").

While here, moved the comment for define GP_ISEL_TPG_MODE to the
appropriate place.

[1] a1b673258f/drivers/media/pci/atomisp/css/sh_css.c (L552-L558)
[2] https://github.com/intel-aero/linux-kernel/search?q=IS_ISP_2400_SYSTEM

  ## `isys_stream_descr->polling_mode` case

This does not exist on the intel-aero atomisp. This is because it is
based on css version irci_stable_candrpv_0415_20150521_0458.

On the other hand, the upstreamed atomisp is based on the following css
version depending on the ISP version using ifdefs:

  - ISP2400: irci_stable_candrpv_0415_20150521_0458
  - ISP2401: irci_master_20150911_0724

The `isys_stream_descr->polling_mode` usage was added on updating css
version to irci_master_20150701_0213 [3].

So, it is not a ISP version specific thing, but css version specific
thing. Because the upstreamed atomisp driver uses irci_master_20150911_0724
for ISP2401, re-add the ISP version check for now.

I say "for now" because ISP2401 should eventually use the same css
version with ISP2400 (i.e., irci_stable_candrpv_0415_20150521_0458)

    ("atomisp2: css2401 and 2401_legacy-irci_master_20150701_0213")
    Link to Intel's Android kernel patch.

 ## `coord = &me->config.internal_frame_origin_bqs_on_sctbl;` case

it was added on commit 4f744a573d ("media: atomisp: make
sh_css_sp_init_pipeline() ISP version independent") for ISP2401. Because
the upstreamed atomisp for the ISP2401 part is based on
irci_master_20150911_0724, hence the difference.

Because the upstreamed atomisp driver uses irci_master_20150911_0724
for ISP2401, revert the test back to `if (IS_ISP2401)`.

3cb3e66f58 media: atomisp: do not use err var when checking port validity for ISP2400
[ Upstream commit 9f6b4fa2d2 ]

Currently, the `port >= N_CSI_PORTS || err` checks for ISP2400 are always
evaluated as true because the err variable is set to `-EINVAL` on
declaration but the variable is never used until the evaluation.

Looking at the diff of commit 3c0538fbad ("media: atomisp: get rid of
most checks for ISP2401 version"), the `port >= N_CSI_PORTS` check is
for ISP2400 and the err variable check is for ISP2401. Fix this issue
by adding ISP version test there accordingly.

fb370f6dc7 media: atomisp: fix punit_ddr_dvfs_enable() argument for mrfld_power up case
[ Upstream commit 5bfbf65fcc ]

When comparing with intel-aero atomisp [1], it looks like
punit_ddr_dvfs_enable() should take `false` as an argument on mrfld_power
up case.

Code from the intel-aero kernel [1]:

        int atomisp_mrfld_power_down(struct atomisp_device *isp)
        {
        [...]
		/*WA:Enable DVFS*/
		if (IS_CHT)
			punit_ddr_dvfs_enable(true);

        int atomisp_mrfld_power_up(struct atomisp_device *isp)
        {
        [...]
		/*WA for PUNIT, if DVFS enabled, ISP timeout observed*/
		if (IS_CHT)
			punit_ddr_dvfs_enable(false);

This patch fixes the inverted argument as per the intel-aero code, as
well as its comment. While here, fix space issues for comments in
atomisp_mrfld_power().

Note that it does not seem to be possible to unify the up/down cases for
punit_ddr_dvfs_enable(), i.e., we can't do something like the following:

        if (IS_CHT)
		punit_ddr_dvfs_enable(!enable);

because according to the intel-aero code [1], the DVFS is disabled
before "writing 0x0 to ISPSSPM0 bit[1:0]" and the DVFS is enabled after
"writing 0x3 to ISPSSPM0 bit[1:0]".

9bfed11dcf ath11k: Send PPDU_STATS_CFG with proper pdev mask to firmware
[ Upstream commit 16a2c3d540 ]

HTT_PPDU_STATS_CFG_PDEV_ID bit mask for target FW PPDU stats request message
was set as bit 8 to 15. Bit 8 is reserved for soc stats and pdev id starts from
bit 9. Hence change the bitmask as bit 9 to 15 and fill the proper pdev id in
the request message.

In commit 701e48a43e ("ath11k: add packet log support for QCA6390"), both
HTT_PPDU_STATS_CFG_PDEV_ID and pdev_mask were changed, but this pdev_mask
calculation is not valid for platforms which has multiple pdevs with 1 rxdma
per pdev, as this is writing same value(i.e. 2) for all pdevs.  Hence fixed it
to consider pdev_idx as well, to make it compatible for both single and multi
pd cases.

22406ed4e3 wcn36xx: populate band before determining rate on RX
[ Upstream commit c9c5608faf ]

status.band is used in determination of status.rate -- for 5GHz on legacy
rates there is a linear shift between the BD descriptor's rate field and
the wcn36xx driver's rate table (wcn_5ghz_rates).

We have a special clause to populate status.band for hardware scan offload
frames. However, this block occurs after status.rate is already populated.
Correctly handle this dependency by moving the band block before the rate
block.

This patch addresses kernel warnings & missing scan results for 5GHz APs
that send their beacons/probe responses at the higher four legacy rates
(24-54 Mbps), when using hardware scan offload:

fcb267bb95 wcn36xx: ensure pairing of init_scan/finish_scan and start_scan/end_scan
[ Upstream commit 8f1ba8b0ee ]

An SMD capture from the downstream prima driver on WCN3680B shows the
following command sequence for connected scans:

- init_scan_req
    - start_scan_req, channel 1
    - end_scan_req, channel 1
    - start_scan_req, channel 2
    - ...
    - end_scan_req, channel 3
- finish_scan_req
- init_scan_req
    - start_scan_req, channel 4
    - ...
    - end_scan_req, channel 6
- finish_scan_req
- ...
    - end_scan_req, channel 165
- finish_scan_req

Upstream currently never calls wcn36xx_smd_end_scan, and in some cases[1]
still sends finish_scan_req twice in a row or before init_scan_req. A
typical connected scan looks like this:

- init_scan_req
    - start_scan_req, channel 1
- finish_scan_req
- init_scan_req
    - start_scan_req, channel 2

- finish_scan_req
- finish_scan_req

This patch cleans up scanning so that init/finish and start/end are always
paired together and correctly nested.

- init_scan_req
    - start_scan_req, channel 1
    - end_scan_req, channel 1
- finish_scan_req
- init_scan_req
    - start_scan_req, channel 2
    - end_scan_req, channel 2
- ...
    - start_scan_req, channel 165
    - end_scan_req, channel 165
- finish_scan_req

Note that upstream will not do batching of 3 active-probe scans before
returning to the operating channel, and this patch does not change that.
To match downstream in this aspect, adjust IEEE80211_PROBE_DELAY and/or
the 125ms max off-channel time in ieee80211_scan_state_decision.

[1]: commit d195d7aac0 ("wcn36xx: Ensure finish scan is not requested
before start scan") addressed one case of finish_scan_req being sent
without a preceding init_scan_req (the case of the operating channel
coinciding with the first scan channel); two other cases are:
1) if SW scan is started and aborted immediately, without scanning any
   channels, we send a finish_scan_req without ever sending init_scan_req,
   and
2) as SW scan logic always returns us to the operating channel before
   calling wcn36xx_sw_scan_complete, finish_scan_req is always sent twice
   at the end of a SW scan

e53ff4dd70 drm/vc4: hdmi: Set a default HSM rate
[ Upstream commit 3e85b81591 ]

When the firmware doesn't setup the HSM rate (such as when booting
without an HDMI cable plugged in), its rate is 0 and thus any register
access results in a CPU stall, even though HSM is enabled.

Let's enforce a minimum rate at boot to avoid this issue.

b9c2343373 clk: bcm-2835: Remove rounding up the dividers
[ Upstream commit 8ca011ef4a ]

The driver, once it found a divider, tries to round it up by increasing
the least significant bit of the fractional part by one when the
round_up argument is set and there's a remainder.

However, since it increases the divider it will actually reduce the
clock rate below what we were asking for, leading to issues with
clk_set_min_rate() that will complain that our rounded clock rate is
below the minimum of the rate.

Since the dividers are fairly precise already, let's remove that part so
that we can have clk_set_min_rate() working.

This is effectively a revert of 9c95b32ca0 ("clk: bcm2835: add a round
up ability to the clock divisor").
