rxrpc: Tracing updates
Here are some patches that update tracing in AF_RXRPC and AFS:
(1) Add a tracepoint for tracking resend events.
(2) Use debug_ids in traces rather than pointers (as pointers are now hashed)
and allow use of the same debug_id in AFS calls as in the corresponding
AF_RXRPC calls. This makes filtering the trace output much easier.
(3) Add a tracepoint for tracking call completion.

In ca8210_test_int_user_write() a user can request the transfer of a
frame with a length field (command.length) that is longer than the
actual buffer provided (len). In this scenario the driver will copy
the buffer contents into the uninitialised command[] buffer, then
transfer <data.length> bytes over the SPI even though only <len> bytes
had been populated, potentially leaking sensitive kernel memory.
Also the first 6 bytes of the command buffer must be initialised in case
a malformed, short packet is written and the uninitialised bytes are
read in ca8210_test_check_upstream.

* enable chip temperature measurement for QCA6174/QCA9377
* add firmware memory dump for QCA9984
* enable buffer STA on TDLS link for QCA6174
* support different beacon internals in multiple interface scenario
for QCA988X/QCA99X0/QCA9984/QCA4019
This is the EAPoL over nl80211 patchset from Denis Kenzior, minus some
infrastructure patches I'd split out and applied earlier. Denis described
it as follows:
This patchset adds support for running 802.11 authentication mechanisms (e.g.
802.1X, 4-Way Handshake, etc) over NL80211 instead of putting them onto the
network device. This has the advantage of fixing several long-standing race
conditions that result from userspace operating on multiple transports in order
to manage a 802.11 connection (e.g. NL80211 and wireless netdev, wlan0, etc).
For example, userspace would sometimes see 4-Way handshake packets before
NL80211 signaled that the connection has been established. Leading to ugly
hacks or having the STA wait for retransmissions from the AP.
This also provides a way to mitigate a particularly nasty race condition where
the encryption key could be set prior to the 4-way handshake packet 4/4 being
sent. This would result in the packet being sent encrypted and discarded by
the peer. The mitigation strategy for this race is for userspace to explicitly
tell the kernel that a particular EAPoL packet should not be encrypted.
To make this possible this patchset introduces a new NL80211 command and several
new attributes. A userspace that is capable of processing EAPoL packets over
NL80211 includes a new NL80211_ATTR_CONTROL_PORT_OVER_NL80211 attribute in its
NL80211_CMD_ASSOCIATE or NL80211_CMD_CONNECT requests being sent to the kernel.
The previously added NL80211_ATTR_SOCKET_OWNER attribute must also be included.
The latter is used by the kernel to send NL80211_CMD_CONTROL_PORT_FRAME
notifications back to userspace via a netlink unicast. If the
NL80211_ATTR_CONTROL_PORT_OVER_NL80211 attribute is not specified, then legacy
behavior is kept and control port packets continue to flow over the network
interface.
If control port over nl80211 transport is requested, then control port packets
are intercepted just prior to being handed to the network device and sent over
netlink via the NL80211_CMD_CONTROL_PORT_FRAME notification.
NL80211_ATTR_CONTROL_PORT_ETHERTYPE and NL80211_ATTR_MAC are included to
specify the control port frame protocol and source address respectively. If
the control port frame was received unencrypted then
NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT flag is also included. NL80211_ATTR_FRAME
attribute contains the raw control port frame with all transport layer headers
stripped (e.g. this would be the raw EAPoL frame).
Userspace can reply to control port frames either via legacy methods (by sending
frames to the network device) or via NL80211_CMD_CONTROL_PORT_FRAME request.
Userspace would included NL80211_ATTR_FRAME with the raw control port frame as
well as NL80211_Attr_MAC and NL80211_ATTR_CONTROL_PORT_ETHERTYPE attributes to
specify the destination address and protocol respectively. This allows
Pre-Authentication (protocol 0x88c7) frames to be sent via this mechanism as
well. Finally, NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT flag can be included to
tell the driver to send the frame unencrypted, e.g. for 4-Way handshake 4/4
frames.
The proposed patchset has been tested in a mac80211_hwsim based environment with
hostapd and iwd.

This commit implements the TX side of NL80211_CMD_CONTROL_PORT_FRAME.
Userspace provides the raw EAPoL frame using NL80211_ATTR_FRAME.
Userspace should also provide the destination address and the protocol
type to use when sending the frame. This is used to implement TX of
Pre-authentication frames. If CONTROL_PORT_ETHERTYPE_NO_ENCRYPT is
specified, then the driver will be asked not to encrypt the outgoing
frame.
A new EXT_FEATURE flag is introduced so that nl80211 code can check
whether a given wiphy has capability to pass EAPoL frames over nl80211.

NL80211_CMD_ASSOCIATE, NL80211_CMD_START_AP or IBSS/mesh join.

In the current implementation, mac80211 advertises the support of
AP_VLANs based on the driver's support for AP mode; it also
blocks encrypted AP_VLAN operation on devices advertising
SW_CRYPTO_CONTROL.
The implementation seems weird in it's current form and could be
often confusing, this is because there can be drivers advertising
both SW_CRYPTO_CONTROL and AP mode support (ex: ath10k) in which case
AP_VLAN will still be supported but only in open BSS and not in
secured BSS.
When SW_CRYPTO_CONTROL is enabled, it makes more sense if the decision
to support AP_VLANs is left to the driver. Mac80211 can then allow
AP_VLAN operations depending on the driver support.

1. When using mac80211 default values;
2. When the userspace tries to configure its own values;
3. When associating to an AP which advertises WWM IE.
When associating to an AP, the client uses the values in the
advertised WMM IE. But the AP may not comply with the new ETSI
requirements, so the client needs to check the current regulatory
rules and use those limits accordingly.

wcn36xx_start_tx function retrieves the buffer descriptor from the
channel control queue to start filling tx buffer information. However,
nothing prevents this same buffer to be concurrently accessed in a
concurent tx call, leading to potential buffer coruption and firmware
crash (observed during iperf test). The channel control queue should
only be accessed and updated with the channel lock.
Fix this issue by using a local buffer descriptor which will be copied
in the thread-safe wcn36xx_dxe_tx_frame.
Note that buffer descriptor size is few bytes so the introduced copy
overhead is insignificant. Moreover, this allows to keep the locked

specific enum value(ieee80211_sta_rx_bw) and which is not
understand by userspace application. Map the mac80211 specific
value to nl80211_chan_width enum value to avoid using wrong value
in the userspace application. And used station's ht/vht capability
to map IEEE80211_STA_RX_BW_20 and IEEE80211_STA_RX_BW_160 with
proper nl80211 value.

SMPS_MODE change value notified via nl80211 contains mac80211
specific value(ieee80211_smps_mode) and user space application
will not know those values. This patch add support to map
the mac80211 enum value to nl80211_smps_mode which will be
understood by the userspace application.

Currently bw and smps_mode are u8 type value in sta_opmode_info
structure. This values filled in mac80211 from ieee80211_sta_rx_bandwidth
and ieee80211_smps_mode. These enum values are specific to mac80211 and
userspace/cfg80211 doesn't know about that. This will lead to incorrect
result/assumption by the user space application.
Change bw and smps_mode parameters to their respective enums in nl80211.
