[ Upstream commit cb88d01b67383a095e3f7caeb4cdade5a6cf0417 ]
We can currently get a "command execute failure 19" error on beacon loss
if the signal is weak:
wlcore: Beacon loss detected. roles:0xff
wlcore: Connection loss work (role_id: 0).
...
wlcore: ERROR command execute failure 19
...
WARNING: CPU: 0 PID: 1552 at drivers/net/wireless/ti/wlcore/main.c:803
...
(wl12xx_queue_recovery_work.part.0 [wlcore])
(wl12xx_cmd_role_start_sta [wlcore])
(wl1271_op_bss_info_changed [wlcore])
(ieee80211_prep_connection [mac80211])
Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware,
and seems to mean that the firmware no longer wants to see the quirk
handling for WLCORE_QUIRK_START_STA_FAILS done.
This quirk got added with commit 18eab430700d ("wlcore: workaround
start_sta problem in wl12xx fw"), and it seems that this already got fixed
in the firmware long time ago back in 2012 as wl18xx never had this quirk
in place to start with.
As we no longer even support firmware that early, to me it seems that it's
safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks
like earlier firmware got disabled back in 2013 with commit 0e284c074ef9
("wl12xx: increase minimum singlerole firmware version required").
If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any
firmware that the driver works with, we can simply revert this patch and
add extra checks for firmware version used.
With this fix wlcore reconnects properly after a beacon loss.

[ Upstream commit b55379e343a3472c35f4a1245906db5158cab453 ]
Failed to transmit wmi management frames:
[84977.840894] ath10k_snoc a000000.wifi: wmi mgmt tx queue is full
[84977.840913] ath10k_snoc a000000.wifi: failed to transmit packet, dropping: -28
[84977.840924] ath10k_snoc a000000.wifi: failed to submit frame: -28
[84977.840932] ath10k_snoc a000000.wifi: failed to transmit frame: -28
This issue is caused by race condition between skb_dequeue and
__skb_queue_tail. The queue of ‘wmi_mgmt_tx_queue’ is protected by a
different lock: ar->data_lock vs list->lock, the result is no protection.
So when ath10k_mgmt_over_wmi_tx_work() and ath10k_mac_tx_wmi_mgmt()
running concurrently on different CPUs, there appear to be a rare corner
cases when the queue length is 1,
CPUx (skb_deuque) CPUy (__skb_queue_tail)
next=list
prev=list
struct sk_buff *skb = skb_peek(list); WRITE_ONCE(newsk->next, next);
WRITE_ONCE(list->qlen, list->qlen - 1);WRITE_ONCE(newsk->prev, prev);
next = skb->next; WRITE_ONCE(next->prev, newsk);
prev = skb->prev; WRITE_ONCE(prev->next, newsk);
skb->next = skb->prev = NULL; list->qlen++;
WRITE_ONCE(next->prev, prev);
WRITE_ONCE(prev->next, next);
If the instruction ‘next = skb->next’ is executed before
‘WRITE_ONCE(prev->next, newsk)’, newsk will be lost, as CPUx get the
old ‘next’ pointer, but the length is still added by one. The final
result is the length of the queue will reach the maximum value but
the queue is empty.
So remove ar->data_lock, and use 'skb_queue_tail' instead of
'__skb_queue_tail' to prevent the potential race condition. Also switch
to use skb_queue_len_lockless, in case we queue a few SKBs simultaneously.

[ Upstream commit af4b3a6f36d6c2fc5fca026bccf45e0fdcabddd9 ]
The Predia Basic tablet contains quite generic names in the sys_vendor and
product_name DMI strings, without this patch brcmfmac will try to load:
brcmfmac43340-sdio.Insyde-CherryTrail.txt as nvram file which is a bit
too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Predia Basic tablet.

[ Upstream commit a338c874d3d9d2463f031e89ae14942929b93db6 ]
The Voyo winpad A15 tablet contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt
as nvram file which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.
While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.

From: Vsevolod Kozlov <zaba@mm.st>
[ Upstream commit 6fe91b69ceceea832a73d35185df04b3e877f399 ]
ac_classify() expects a struct sk_buff* as its second argument, which is
a member of struct tx_complete_data. priv happens to be a pointer to
struct tx_complete_data, so passing it directly to ac_classify() leads
to wrong behaviour and occasional panics.
Since there is only one caller of wilc_wlan_txq_add_net_pkt and it
already knows the type behind this pointer, and the structure is already
in the header file, change the function signature to use the real type
instead of void* in order to prevent confusion.
