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.

When connect to an AP with WPA mode, ath10k need to set need_ptk_4_way to
firmware in WMI_PEER_ASSOC_CMD, then the data path is disallow in
firmware, it will be allowed untill firmware finish the 4 way handshake.
It failed with a test case with below steps:
1. configure AP with WPA mode with ssid1 SimpleConnect_a_orbvt_ch1,
bssid1 and channel 1.
2. connect to ssid1 and ping success.
3. wait 10 seconds which is less than
IEEE80211_SCAN_RESULT_EXPIRE(30 seconds).
4. configure AP with OPEN mode with ssid2 SimpleConnect_b_z3a00_ch1,
but use same bssid1 and channel 1 of step 1.
5. disconnect ssid1.
6. connect to ssid2 and ping fail.
Fail reason:
When run step 6, ath10k_peer_assoc_h_crypto() called cfg80211_get_bss()
with bssid and chan info, but ssid1 and ssid2 have the same bssid and
channel, then there have 2 entry for ssid1 and ssid2 in cfg80211. The
ssid1's order is before ssid2 in bss_list, and ssid1's age is less than
the expire time which is IEEE80211_SCAN_RESULT_EXPIRE(30 seconds). Then
ssid1's entry is selected and ath10k_peer_assoc_h_crypto() parsed it and
get the rsnie and then need_ptk_4_way is set to firmware, so data path
is disallowed and it will not receive 4 way handshake for OPEN mode,
so ping fail in step 6.
This patch is to pass the ssid info to cfg80211_get_bss() as same as
cfg80211_mlme_assoc() and cfg80211_mlme_auth(), then it will find the
correct bss entry in above test case, then case success.
For AP mode, the ssid info is filled in ieee80211_start_ap(), for STATION
mode, it is filled in ieee80211_mgd_assoc(). Tested for both AP/STATION
mode with QCA6174 hw3.2 PCI, it is success start/connect/ping for
WPA/OPEN mode.

ath10k assigns ath10k_mac_set_sar_specs to ath10k_ops, and
this function is called when user space application calls
NL80211_CMD_SET_SAR_SPECS. ath10k also registers SAR type,
and supported frequency ranges to wiphy so user space can
query SAR capabilities.
This SAR power limitation is compared to regulatory txpower
and selects the minimal one to set when station is connected.
Otherwise, it delays until the station is connected. If the
station is disconnected, it returns to regulatory txpower.
This feature is controlled by hw parameter: dynamic_sar_support.

Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.
For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.
This patch now increases the maxmimum frame size from 1528 to 1656
bytes.
Tested with two ath10k devices in 802.11s mode, as well as with
batman-adv on top of 802.11s with forwarding disabled.

MPTCP: Add MP_PRIO support and rework local address IDs
Patches 1 and 2 rework the assignment of local address IDs to allow them
to be assigned by a userspace path manager, and add corresponding self
tests.
Patches 2-8 add the ability to change subflow priority after a subflow
has been established. Each subflow in a MPTCP connection has a priority
level: "regular" or "backup". Data should only be sent on backup
subflows if no regular subflows are available. The priority level can be
set when the subflow connection is established (as was already
implemented), or during the life of the connection by sending MP_PRIO in
the TCP options (as added here). Self tests are included.

solve the rtnl lock issue. Majority of the code in do_change_param_reset
duplicates do_reset. Also, we can handle the rtnl lock issue in do_reset
itself. Hence merge do_change_param_reset back into do_reset to clean up
the code.

sparse complains about some harmless endianness issues:

Here 'ack' is assigned a value in network-order, and then also the
byte-swapped value in host-order. Clean this up by doing the byte-swap
as part of the assignment.

Here we use the wrong flavour of byte-swap. Use ntohs(), which of course
gives the same result.

iptunnel_pmtud_build_icmp() uses the wrong flavour of byte-order conversion
when storing the MTU into the ICMPv4 packet. Use htons(), just like
iptunnel_pmtud_build_icmpv6() does.

eth_header() wants the Ethertype in host-order, use the correct flavour of
byte-order conversion.

The TUNNEL_* types are big-endian, so adjust the type of the local
variable in ip_tun_parse_opts().

UniMAC is integrated into multiple Broadcom's Ethernet controllers so
use a shared header file for it and avoid some code duplication.
