08aa80777b wifi: rtw89: correct BA CAM allocation
BA CAM entries are global resource of hardware, so move the bitmap and
instances to rtw89_cam_info, and then use link list from rtw89_sta to
these instances.

To check the allocation, add ba_cam to debugfs:

  map:
  	mac_id:    01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

deebea35d6 wifi: rtw89: early recognize FW feature to decide if chanctx
In current flow, FW is asynchronously loaded after alloc_hw(). It defers
the decision on FW feature map. It makes things difficult for us to decide
whether to hook chanctx ops, which should be decided while alloc_hw() is
calling. Still, asynchronous gets its advantages. So, we want to resolve
this without dropping them.

Based on multi-FW flag, RTW89_MFW_SIG, we can determine runtime FW is
multi-FW (MFW) or single FW (SFW). Both of them have a quite small chunk
for header at the head. The difference is that MFW doesn't describe version
code in its header while SFW does. So, we plan to extend MFW header for
version code. After that, in both cases, we can determine FW feature map by
just FW header. And, according to the map, we can decide chanctx.

So, we call request_partial_firmware_into_buf() to request a quite small
chunk before alloc_hw() to get a early FW feature map without affecting
things much and only use early map to decide whether to hook chanctx ops.

It means that if non-extended MFW is used at runtime, driver just acts
without chanctx as before. If extended MFW or SFW, which supports required
FW features, is used at runtime, driver can hook chanctx ops to mac80211 if
chip has configured support_chanctx_num > 0.

Besides, key point for now to support single one chanctx is whether HW scan
is supported at runtime. So, we configure all chip's support_chanctx_num to
1, and check if HW scan is supported at runtime via early FW feature map.

7fc06a071c wifi: rtw89: declare support for mac80211 chanctx ops by chip
Some HW features are required if we hook chanctx ops to mac80211. With it,
mac80211 would expect the HW-supported variant ops exists on some behavior,
e.g. HW scan. But, HW features may depend on chip's FW or its development.
Besides, how many chanctx can be supported also depends on chip design.
We can neither decide whether to generally support chanctx ops nor how many
chanctx can be supported.

So, support_chanctx_num is added under chip info to deal with this by chip.
For now, all chip configure support_chanctx_num as 0. We haven't really
hook chanctx ops yet. So, chip can run without mac80211 chanctx as before.

For now, we support single one channel and use only first HW entry,
i.e. RTW89_SUB_ENTITY_0, RTW89_MAC_0, RTW89_PHY_0. Without something
unexpected, the entity mode should always be RTW89_ENT_MODE_SCC after

a88b6cc483 wifi: rtw89: initialize entity and configure default chandef
While idle, we need a default chandef to set channel for things,
such as scan. Before support of mac80211 chanctx, mac80211 would
configure a default one on ieee80211_hw::conf::chandef. And we
just queried it whenever we did set channel. However, after support
of mac80211 chanctx, the flow won't work like before.

Besides, we don't now query chandef from ieee80211_hw::conf::chandef
either. So, similar to mac80211 without using chanctx, we configure
the default chandef with ieee80211_channel of index 0 in 2GHz.

Although we have not added the support of mac80211 chanctx here,
this configuration should be compatible before that. So, we commit
this ahead.

Originally, we didn't support mac80211 chanctx, so it's expected that

However, we are planing to support mac80211 chanctx. After that, the
above assumption would be broken. So, we adjust a bit ahead to reduce
future works about mac80211 chanctx.

After this, we don't query ieee80211_hw::conf::chandef directly, and
we add a map, entity_map, to HAL to indicate which chandef came from
stack. And it will later be used to recalcate entity mode.

Besides, fix rtw8852a_set_txpwr_offset() from rtw8852a_set_txpwr_ctrl()

e.g. during HW scan, we adjust it to align FW process through C2H.
However, we don't have full parameters to fill entire rtw89_chan.
And it will breakage if we update only part of current rtw89_chan.
That is what we don't want to see because most flows throughout
driver treat rtw89_chan as a whole.

So, we divide struct rtw89_chan to basic part and derived part. The
basic part contains the parameters which we are always able to know.
And the derived part will be calculated by the basic part. Then, a
central function, rtw89_chan_create(), is added to deal with this.

cbb145b98b wifi: rtw89: re-arrange channel related stuffs under HAL
We are planning to support mac80211 chanctx. To reduce future works,
the driver architecture is adjusted first to isolate related things.

According to chip, our HW may have multiple sub-entities to support
multiple mac80211 chanctx. Struct rtw89_chan has been introduced for
things about channel/band/subband/... Now introduce struct rtw89_chan_rcd
to record difference after assigning new one of struct rtw89_chan.

We will implement and support chanctx with single channel first, i.e.
only use entry in RTW89_SUB_ENTITY_0, before handling dual channels.

Our hierarchy in planning will become as the following.
DEV
-> HAL
---> entity (manage status across sub-entities)
-----> sub-entity[*] (support mac80211 chanctx)
where each sub-entity contains one struct rtw89_chan.

3e5831cac1 wifi: rtw89: introduce rtw89_chan for channel stuffs
Introduce struct rtw89_chan ahead to encapsulate stuffs from struct
rtw89_channel_params. These stuffs have a clone in HAL and are used
throughout driver. After multiple channels support, it's expected that
each channel instance has a configuration of them. So, we refine them
with struct rtw89_chan by precise type first, and will re-arrange HAL
by struct rtw89_chan in the following as well.

(No logic has changed.)

967439c7a2 wifi: rtw89: rewrite decision on channel by entity state
We need to invoke the callback of the changed band at the first
set_channel() after every power-off. Originally, we forced the
channel to be 0 when doing power-off, and then determined things
by comparing channel with 0.

However, deciding on such things by channel might be confusing.
It's also confusing to use this kind of decision when we consider
multiple channels in the follow-up patches. So, another flag,
entity_active, is added ahead to HAL to deal with this.

Besides, we also need to check if entity is active when we set
TX power.

b383e8abed wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg()
syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for
ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with
pkt_len = 0 but ath9k_hif_usb_rx_stream() uses
__dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that
pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb
with uninitialized memory and ath9k_htc_rx_msg() is reading from
uninitialized memory.

Since bytes accessed by ath9k_htc_rx_msg() is not known until
ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid
pkt_len at "if (pkt_len > 2 * MAX_RX_BUF_SIZE) {" line in
ath9k_hif_usb_rx_stream().

We have two choices. One is to workaround by adding __GFP_ZERO so that
ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to let
ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose
the latter.

Note that I'm not sure threshold condition is correct, for I can't find
details on possible packet length used by this protocol.

Also, systems compatible with this dock provide a BIOS option to enable
MAC address passthrough (as per Lenovo document "ThinkPad Docking
Solutions 2017"). Add the custom PID to the MAC passthrough list too.

Tested on a ThinkPad 13 1st gen with the expected results:

44af95718f net: prestera: manage matchall and flower priorities
matchall rules can be added only to chain 0 and their priorities have
limitations:
 - new matchall ingress rule's priority must be higher (lower value)
   than any existing flower rule;
 - new matchall egress rule's priority must be lower (higher value)
   than any existing flower rule.

The opposite works for flower rule adding:
 - new flower ingress rule's priority must be lower (higher value)
   than any existing matchall rule;
 - new flower egress rule's priority must be higher (lower value)
   than any existing matchall rule.

This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.

To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.
