mac80211: ath11k: sync with ath-next

Browse Source 
Synchronize the ath11k backports with the current ath-next tree.

This replaces the 160MHz with the upstreamed one, fixes 6GHz only WIPHY
registration, allows SAR usage on WCN6750 and plenty of REO fixes.

Subject: [PATCH] wifi: ath11k: Remove redundant pci_clear_master
Remove pci_clear_master to simplify the code,
the bus-mastering is also cleared in do_pci_disable_device,
like this:
./drivers/pci/pci.c:2197
static void do_pci_disable_device(struct pci_dev *dev)
{
u16 pci_command;
pci_read_config_word(dev, PCI_COMMAND, &pci_command);
if (pci_command & PCI_COMMAND_MASTER) {
pci_command &= ~PCI_COMMAND_MASTER;
pci_write_config_word(dev, PCI_COMMAND, pci_command);
}
pcibios_disable_device(dev);
}.
And dev->is_busmaster is set to 0 in pci_disable_device.

Subject: [PATCH] wifi: ath11k: pci: Add more MODULE_FIRMWARE() entries
As there are a few more models supported by the driver, let's add the
missing MODULE_FIRMWARE() entries for them. The lack of them resulted
in the missing device enablement on some systems, such as the
installation image of openSUSE.
While we are at it, use the wildcard instead of listing each firmware
files individually for each.

Subject: [PATCH] wifi: ath11k: Ignore frags from uninitialized peer in dp.
When max virtual ap interfaces are configured in all the bands with
ACS and hostapd restart is done every 60s, a crash is observed at
random times.
In this certain scenario, a fragmented packet is received for
self peer, for which rx_tid and rx_frags are not initialized in
datapath. While handling this fragment, crash is observed as the
rx_frag list is uninitialised and when we walk in
ath11k_dp_rx_h_sort_frags, skb null leads to exception.
To address this, before processing received fragments we check
dp_setup_done flag is set to ensure that peer has completed its
dp peer setup for fragment queue, else ignore processing the
fragments.

Subject: [PATCH] wifi: ath11k: fix double free of peer rx_tid during reo cmd
failure
Peer rx_tid is locally copied thrice during peer_rx_tid_cleanup to
send REO_CMD_UPDATE_RX_QUEUE followed by REO_CMD_FLUSH_CACHE to flush
all aged REO descriptors from HW cache.
When sending REO_CMD_FLUSH_CACHE fails, we do dma unmap of already
mapped rx_tid->vaddr and free it. This is not checked during
reo_cmd_list_cleanup() and dp_reo_cmd_free() before trying to free and
unmap again.
Fix this by setting rx_tid->vaddr NULL in rx tid delete and also
wherever freeing it to check in reo_cmd_list_cleanup() and
reo_cmd_free() before trying to free again.

Subject: [PATCH] wifi: ath11k: Prevent REO cmd failures
Prevent REO cmd failures causing double free by increasing REO cmd
ring size and moving REO status ring mask to IRQ group 3 from group
0 to separate from tx completion ring on IRQ group 0 which may delay
reo status processing.

During reo command failure, the peer mac detail for which the reo
command was not successful is unknown. Hence, to improve the
debuggability, add the peer mac information in the failure cases
which would be useful during multi client cases.

Subject: [PATCH] wifi: ath11k: fix tx status reporting in encap offload mode
ieee80211_tx_status() treats packets in 802.11 frame format and
tries to extract sta address from packet header. When tx encap
offload is enabled, this becomes invalid operation. Hence, switch
to using ieee80211_tx_status_ext() after filling in station
address for handling both 802.11 and 802.3 frames.

Subject: [PATCH] wifi: ath11k: Fix SKB corruption in REO destination ring
While running traffics for a long time, randomly an RX descriptor
filled with value "0" from REO destination ring is received.
This descriptor which is invalid causes the wrong SKB (SKB stored in
the IDR lookup with buffer id "0") to be fetched which in turn
causes SKB memory corruption issue and the same leads to crash
after some time.
Changed the start id for idr allocation to "1" and the buffer id "0"
is reserved for error validation. Introduced Sanity check to validate
the descriptor, before processing the SKB.
Crash Signature :
Unable to handle kernel paging request at virtual address 3f004900
PC points to "b15_dma_inv_range+0x30/0x50"
LR points to "dma_cache_maint_page+0x8c/0x128".

capability flags and assign valid center frequency 2 similar to
VHT80_80.

Subject: [PATCH] wifi: ath11k: fix registration of 6Ghz-only phy without the
full channel range
Because of what seems to be a typo, a 6Ghz-only phy for which the BDF
does not allow the 7115Mhz channel will fail to register:

This is a regression fix for 80+80 and 160 MHz support bits being
cleared, therefore not adverised. Remove disable of 80+80 and 160 MHz
capability flags and assign valid center frequency 2 similar to
VHT80_80.
