wifi: iwlwifi: mvm: implement PHC clock adjustments
Implement the following PHC operations:
1. adjtime - for adding an offset to the PHC clock time.
2. adjfine - for adjusting the PHC clock frequency.
3. gettime64 - for getting the PHC clock time. This function returns
the time as adjusted by adjtime and adjfine.
The adjusted time will also be used for time sync frames timestamping.

For TM/FTM frames, report the hardware timestamps reported by the

in a dedicated notification (and not as part of the RX/TX status),
hold the frame until the fw timestamps notification is received.
Timestamping is enabled when a station is connected and disabled

wifi: rtl8xxxu: Support new chip RTL8710BU aka RTL8188GU
This chip is found in cheap "free driver" USB adapters from Aliexpress.
Initially they pretend to be a CD-ROM containing the driver for Windows.
"Ejecting" switches the device to wifi mode.
Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.
This chip is more unique than other Realtek chips:
* The registers at addresses 0x0-0xff, which all the other chips use,
can't be used here. New registers at 0x8000-0x80ff must be used
instead. And it's not a simple matter of adding 0x8000: 0x2
(REG_SYS_FUNC) became 0x8004, 0x80 (REG_MCU_FW_DL) became 0x8090,
etc.
* Also there are a few new registers which must be accessed indirectly
because their addresses don't fit in 16 bits. No other chips seem to
have these.
* The vendor driver compiles to 8188gu.ko, but the code calls the chip
RTL8710B(U) pretty much everywhere, including messages visible to the
user.
Another difference compared to the other chips supported by rtl8xxxu is
that it has a new PHY status struct, or three of them actually, from
which we extract the RSSI, among other things. This is not unique,
though, just new. The chips supported by rtw88 also use it.

Always run the entire init sequence (rtl8xxxu_init_device()) for

This fixes a bug where the device is unable to connect after
rebooting:
wlp3s0f3u2: send auth to ... (try 1/3)
wlp3s0f3u2: send auth to ... (try 2/3)
wlp3s0f3u2: send auth to ... (try 3/3)

firmware is still running), but not really in a working state.

wifi: iwlwifi: mvm: avoid sta lookup in queue alloc
In FW restart scenarios, we allocate the queues from the
iwl_mvm_realloc_queues_after_restart() function, but that
is called before we insert the station ID into our map
(mvm->fw_id_to_mac_id).
However, in all cases where we're actually allocating a
queue for a "real" (not bcast, aux, ...) station we have
the sta pointer already, so just pass it along to use it
instead of looking it up.
This fixes an issue where after restart we only allocated
a queue of size 16 (due to the ordering issue described
above), and thus never got good throughput again since no
aggregates could be formed on transmit.

wifi: brcmfmac: slab-out-of-bounds read in brcmf_get_assoc_ies()
Fix a slab-out-of-bounds read that occurs in kmemdup() called from
brcmf_get_assoc_ies().
The bug could occur when assoc_info->req_len, data from a URB provided
by a USB device, is bigger than the size of buffer which is defined as
WL_EXTRA_BUF_MAX.
Add the size check for req_len/resp_len of assoc_info.

wifi: qtnfmac: use struct_size and size_sub for payload length
Replace the calculations for the payload length in
qtnf_cmd_band_fill_iftype with struct_size() and size_sub(). While
the payload length does not get directly passed to an allocation function,
the performed calculation is still calculating the size of a flexible array
structure (minus the size of a header structure).

wifi: ipw2x00: convert ipw_fw_error->elem to flexible array[]
The ipw_fw_error structure contains a payload[] flexible array as well as
two pointers to this array area, ->elem, and ->log. The total size of the
allocated structure is computed without use of the <linux/overflow.h>
macros.
There's no reason to keep both a payload[] and an extra pointer to both the
elem and log members. Convert the elem pointer member into the flexible
array member, removing payload.
Fix the allocation of the ipw_fw_error structure to use size_add(),
struct_size(), and array_size() to compute the allocation. This ensures
that any overflow saturates at SIZE_MAX rather than overflowing and
potentially allowing an undersized allocation.
Before the structure change, the layout of ipw_fw_error was:
struct ipw_fw_error {
long unsigned int jiffies; /* 0 8 */
u32 status; /* 8 4 */
u32 config; /* 12 4 */
u32 elem_len; /* 16 4 */
u32 log_len; /* 20 4 */
struct ipw_error_elem * elem; /* 24 8 */
struct ipw_event * log; /* 32 8 */
u8 payload[]; /* 40 0 */
/* size: 40, cachelines: 1, members: 8 */
/* last cacheline: 40 bytes */
};
After this change, the layout is now:
struct ipw_fw_error {
long unsigned int jiffies; /* 0 8 */
u32 status; /* 8 4 */
u32 config; /* 12 4 */
u32 elem_len; /* 16 4 */
u32 log_len; /* 20 4 */
struct ipw_event * log; /* 24 8 */
struct ipw_error_elem elem[]; /* 32 0 */
/* size: 32, cachelines: 1, members: 7 */
/* last cacheline: 32 bytes */
};
This saves a total of 8 bytes for every ipw_fw_error allocation, and
removes the risk of a potential overflow on the allocation.

Provide the Ingress Stage 1 (IS1) VCAP (Versatile Content-Aware
Processor) support for the Lan966x platform.
The IS1 VCAP has 3 lookups and they are accessible with a TC chain id:
- chain
1000000: IS1 Lookup 0
- chain
1100000: IS1 Lookup 1
- chain
1200000: IS1 Lookup 2
The IS1 is capable of different actions like rewrite VLAN tags, change
priority of the frames, police the traffic, etc. These features will be
added at a later point.
The IS1 currently implements the action that allows setting the value
of a PAG (Policy Association Group) key field in the frame metadata and
this can be used for matching in an IS2 VCAP rule. In this way a rule in
IS0 VCAP can be linked to rules in the IS2 VCAP. The linking is exposed
by using the TC "goto chain" action with an offset from the IS2 chain ids.
For example "goto chain
8000001" will use a PAG value of 1 to chain to a
rule in IS2 lookup 0.

As it says in rfc8260#section-3.6 about the weighted fair queueing
scheduler:
A Weighted Fair Queueing scheduler between the streams is used. The
weight is configurable per outgoing SCTP stream. This scheduler
considers the lengths of the messages of each stream and schedules
them in a specific way to use the capacity according to the given
weights. If the weight of stream S1 is n times the weight of stream
S2, the scheduler should assign to stream S1 n times the capacity it
assigns to stream S2. The details are implementation dependent.
Interleaving user messages allows for a better realization of the
capacity usage according to the given weights.
This patch adds Weighted Fair Queueing Scheduler actually based on
the code of Fair Capacity Scheduler by adding fc_weight into struct
sctp_stream_out_ext and taking it into account when sorting stream->
fc_list in sctp_sched_fc_sched() and sctp_sched_fc_dequeue_done().

This patch adds Fair Capacity Scheduler based on the foundations added
by commit
5bbbbe32a431 ("sctp: introduce stream scheduler foundations"):
A fc_list and a fc_length are added into struct sctp_stream_out_ext and
a fc_list is added into struct sctp_stream. In .enqueue, when there are
chunks enqueued into a stream, this stream will be linked into stream->
fc_list by its fc_list ordered by its fc_length. In .dequeue, it always
picks up the 1st skb from stream->fc_list. In .dequeue_done, fc_length
is increased by chunk's len and update its location in stream->fc_list
according to the its new fc_length.
Note that when the new fc_length overflows in .dequeue_done, instead of
resetting all fc_lengths to 0, we only reduced them by U32_MAX / 4 to
avoid a moment of imbalance in the scheduling, as Marcelo suggested.

====================
Various mtk_eth_soc cleanups
Here are a number of patches that do a bit of cleanup to mtk_eth_soc.
The first patch cleans up mtk_gmac0_rgmii_adjust(), which is the
troublesome function preventing the driver becoming a post-March2020
phylink driver. It doesn't solve that problem, merely makes the code
easier to follow by getting rid of repeated tenary operators.
The second patch moves the check for DDR2 memory to the initialisation
of phylink's supported_interfaces - if TRGMII is not possible for some
reason, we should not be erroring out in phylink MAC operations when
that can be determined prior to phylink creation.
The third patch removes checks from mtk_mac_config() that are done
when initialising supported_interfaces - phylink will not call
mtk_mac_config() with an interface that was not marked as supported,
so these checks are redundant.
The last patch removes the remaining vestiges of REVMII and RMII
support, which appears to be entirely unused.
These shouldn't conflict with Daniel's patch set, but if they do I
will rework as appropriate.

net: mtk_eth_soc: remove support for RMII and REVMII modes
Since the conversion of mtk_eth_soc to phylink's supported_interfaces
bitmap, these two modes have not been selectable. No one has raised
this as an issue. Checking the in-kernel DT files, none of them use
either of these modes with this hardware.
Daniel Golle concurs:
A quick grep through the device trees of the more than 650 ramips and
mediatek boards we support in OpenWrt has revealed that *none* of them
uses either reduced-MII or reverse-MII PHY modes. I could imaging that
some more specialized ramips boards may use the RMII 100M PHY mode to
connect with exotic PHYs for industrial or automotive applications
(think: for 100BASE-T1 PHY connected via RMII). I have never seen or
touched such boards, but there are hints that they do exist.
For reverse-MII there are cases in which the Ralink SoC (Rt305x, for
example) is used in iNIC mode, ie. connected as a PHY to another SoC,
and running only a minimal firmware rather than running Linux. Due to
the lack of external DRAM for the Ralink SoC on this kind of boards,
the Ralink SoC there will anyway never be able to boot Linux.
I've seen this e.g. in multimedia devices like early WiFi-connected
not-yet-so-smart TVs.
Consequently, the conclusion is that no one uses these modes with this
hardware, so we might as well drop support for them.

net: mtk_eth_soc: remove unnecessary checks in mtk_mac_config()
mtk_mac_config() checks that the interface mode is permitted for the
capabilities, but we already do these checks in mtk_add_mac() when
initialising phylink's supported_interfaces bitmap. Remove the
unnecessary tests.

net: mtk_eth_soc: move trgmii ddr2 check to probe function
If TRGMII mode is not permitted when using DDR2 mode, we should handle
that when setting up phylink's ->supported_interfaces so phylink knows
that this is not supported by the hardware. Move this check to
mtk_add_mac().
