Support the driver incrementing MIC error and replay detected

instead of relying on mac80211 to do the checks.
These are then exposed to userspace, though currently only in some

The WLAN device may exist yet not be usable. This can happen
when the WLAN device is controllable by both the host and
some platform internal component.
We need some arbritration that is vendor specific, but when
the device is not available for the host, we need to reflect
this state towards the user space.
Add a reason field to the rfkill object (and event) so that
userspace can know why the device is in rfkill: because some
other platform component currently owns the device, or
because the actual hw rfkill signal is asserted.
Capable userspace can now determine the reason for the rfkill
and possibly do some negotiation on a side band channel using
a proprietary protocol to gain ownership on the device in case
the device is owned by some other component. When the host
gains ownership on the device, the kernel can remove the
RFKILL_HARD_BLOCK_NOT_OWNER reason and the hw rfkill state
will be off. Then, the userspace can bring the device up and
start normal operation.
The rfkill_event structure is enlarged to include the additional
byte, it is now 9 bytes long. Old user space will ask to read
only 8 bytes so that the kernel can know not to feed them with
more data. When the user space writes 8 bytes, new kernels will
just read what is present in the file descriptor. This new byte
is read only from the userspace standpoint anyway.
If a new user space uses an old kernel, it'll ask to read 9 bytes
but will get only 8, and it'll know that it didn't get the new
state. When it'll write 9 bytes, the kernel will again ignore
this new byte which is read only from the userspace standpoint.

====================
add ppp_generic ioctl(s) to bridge channels
Following on from my previous RFC[1], this series adds two ioctl calls
to the ppp code to implement "channel bridging".
When two ppp channels are bridged, frames presented to ppp_input() on
one channel are passed to the other channel's ->start_xmit function for
transmission.
The primary use-case for this functionality is in an L2TP Access
Concentrator where PPP frames are typically presented in a PPPoE session
(e.g. from a home broadband user) and are forwarded to the ISP network in
a PPPoL2TP session.
The two new ioctls, PPPIOCBRIDGECHAN and PPPIOCUNBRIDGECHAN form a
symmetric pair.
Userspace code testing and illustrating use of the ioctl calls is
available in the go-l2tp[2] and l2tp-ktest[3] repositories.
[1]. Previous RFC series:
https://lore.kernel.org/netdev/20201106181647.16358-1-tparkin@katalix.com/
[2]. go-l2tp: a Go library for building L2TP applications on Linux
systems. Support for the PPPIOCBRIDGECHAN ioctl is on a branch:
https://github.com/katalix/go-l2tp/tree/tp_002_pppoe_2
[3]. l2tp-ktest: a test suite for the Linux Kernel L2TP subsystem.
Support for the PPPIOCBRIDGECHAN ioctl is on a branch:
https://github.com/katalix/l2tp-ktest/tree/tp_ac_pppoe_tests_2
Changelog:
v4:
* Fix NULL-pointer access in PPPIOCBRIDGECHAN in the case that the
ID of the channel to be bridged wasn't found.
* Add comment in ppp_unbridge_channels to better document the
unbridge process.
v3:
* Use rcu_dereference_protected for accessing struct channel
'bridge' field during updates with lock 'upl' held.
* Avoid race in ppp_unbridge_channels by ensuring that each channel
in the bridge points to it's peer before decrementing refcounts.
v2:
* Add missing __rcu annotation to struct channel 'bridge' field in
order to squash a sparse warning from a C=1 build
* Integrate review comments from gnault@redhat.com
* Have ppp_unbridge_channels return -EINVAL if the channel isn't
part of a bridge: this better aligns with the return code from
ppp_disconnect_channel.
* Improve docs update by including information on ioctl arguments
and error return codes.

This new ioctl pair allows two ppp channels to be bridged together:
frames arriving in one channel are transmitted in the other channel
and vice versa.
The practical use for this is primarily to support the L2TP Access
Concentrator use-case. The end-user session is presented as a ppp
channel (typically PPPoE, although it could be e.g. PPPoA, or even PPP
over a serial link) and is switched into a PPPoL2TP session for
transmission to the LNS. At the LNS the PPP session is terminated in
the ISP's network.
When a PPP channel is bridged to another it takes a reference on the
other's struct ppp_file. This reference is dropped when the channels
are unbridged, which can occur either explicitly on userspace calling
the PPPIOCUNBRIDGECHAN ioctl, or implicitly when either channel in the
bridge is unregistered.
In order to implement the channel bridge, struct channel is extended
with a new field, 'bridge', which points to the other struct channel
making up the bridge.
This pointer is RCU protected to avoid adding another lock to the data
path.
To guard against concurrent writes to the pointer, the existing struct
channel lock 'upl' coverage is extended rather than adding a new lock.
The 'upl' lock is used to protect the existing unit pointer. Since the
bridge effectively replaces the unit (they're mutually exclusive for a
channel) it makes coding easier to use the same lock to cover them
both.

This reverts commit 0a4e9ce17ba77847e5a9f87eed3c0ba46e3f82eb.
The code was developed and tested on an MSC313E SoC, which seems to be
half-way between the AT91RM9200 and the AT91SAM9260 in that it supports
both the 2-descriptors mode and a Tx ring.
It turns out that after the code was merged I could notice that the
controller would sometimes lock up, and only when dealing with sustained
bidirectional transfers, in which case it would report a Tx overrun
condition right after having reported being ready, and will stop sending
even after the status is cleared (a down/up cycle fixes it though).
After adding lots of traces I couldn't spot a sequence pattern allowing
to predict that this situation would happen. The chip comes with no
documentation and other bits are often reported with no conclusive
pattern either.
It is possible that my change is wrong just like it is possible that
the controller on the chip is bogus or at least unpredictable based on
existing docs from other chips. I do not have an RM9200 at hand to test
at the moment and a few tests run on a more recent 9G20 indicate that
this code path cannot be used there to test the code on a 3rd platform.
Since the MSC313E works fine in the single-descriptor mode, and that
people using the old RM9200 very likely favor stability over performance,
better revert this patch until we can test it on the original platform
this part of the driver was written for. Note that the reverted patch
was actually tested on MSC313E.

Packets sent by rmnet to the real device have variable MAP header
lengths based on the data format configured. This patch adds checks
to ensure that the real device MTU is sufficient to transmit the MAP
packet comprising of the MAP header and the IP packet. This check
is enforced when rmnet devices are created and updated and during
MTU updates of both the rmnet and real device.
Additionally, rmnet devices now have a default MTU configured which
accounts for the real device MTU and the headroom based on the data
format.

(dis)connected
When the upper layer instruct us to connect (or disconnect), but we have
already connected (or disconnected), consider this operation successful
rather than failed.
This can help the upper layer to correct its record about whether we are
connected or not here in layer 2.
The upper layer may not have the correct information about whether we are
connected or not. This can happen if this driver has already been running
for some time when the "x25" module gets loaded.
Another X.25 driver (hdlc_x25) is already doing this, so we make this

Add support for M_CAN controller on Intel Elkhart Lake attached to the PCI bus.
It integrates the Bosch M_CAN controller with Message RAM and the wrapper IP
block with additional registers which all of them are within the same MMIO
range.
Currently only interrupt control register from wrapper IP is used and the MRAM
configuration is expected to come from the firmware via "bosch,mram-cfg" device
property and parsed by m_can.c core.
Initial implementation is done by Felipe Balbi while he was working at Intel
with later changes from Raymond Tan and me.

This is a preparatory patch for upcoming PCI based M_CAN devices. The current
PM implementation would cause PCI based drivers to enable PM twice, once when
the PCI device is added and a second time in m_can_class_register(). This will
cause 'Unbalanced pm_runtime_enable!' to be logged, and is a situation that
should be avoided.
Therefore, in anticipation of PCI devices, move PM enabling out from M_CAN
class registration to its only user, the m_can_platform driver.

When CAN_ISOTP_SF_BROADCAST is set in the CAN_ISOTP_OPTS flags the CAN_ISOTP
socket is switched into functional addressing mode, where only single frame
(SF) protocol data units can be send on the specified CAN interface and the
given tp.tx_id after bind().
In opposite to normal and extended addressing this socket does not register a
CAN-ID for reception which would be needed for a 1-to-1 ISOTP connection with a
segmented bi-directional data transfer.
Sending SFs on this socket is therefore a TX-only 'broadcast' operation.

Currently, the driver gets the max rss size from configuration
file when initialization. Both the PF and VF share the same
max rss size, and no more than 128.
For DEVICE_VERSION_V3, the max rss size for PF can be up to
512, so there is a new field in configuration file to store it,
the old filed is used for VF.
To be compatible with boards using old configure file, the PF
will use the old filed if the one is zero.
For the rss size may be larger than 256, so the type of
rss_indirection_tbl of struct hclge_vport should be changed to

Currently, the HNS3 driver only supports offload for tc number
and prio_tc. This patch adds support for other qopts, including
queues count and offset for each tc.
When enable tc mqprio offload, it's not allowed to change
queue numbers by ethtool. For hardware limitation, the queue
number of each tc should be power of 2.
For the queues is not assigned to each tc by average, so it's
should return vport->alloc_tqps for hclge_get_max_channels().

Currently, there are multiple members related to tc information
in struct hnae3_knic_private_info. Merge them into a new struct

====================
Add support for VSOL V2801F/CarlitoxxPro CPGOS03 GPON module
This patch set adds support for the V2801F / CarlitoxxPro module. This
requires two changes:
1) the module only supports single byte reads to the ID EEPROM,
while we need to still permit sequential reads to the diagnostics
EEPROM for atomicity reasons.
2) we need to relax the encoding check when we have no reported
capabilities to allow 1000base-X based on the module bitrate.
Thanks to Pali Rohár for responsive testing over the last two days.
(Resending, dropping the utf-8 characters in Pali's name so the patches
get through vger. Added Andrew's r-b tags.)

Do not check the encoding when deriving 1000BASE-X from the bitrate
when no other modes are discovered. Some GPON modules (VSOL V2801F
and CarlitoxxPro CPGOS03-0490 v2.0) indicate NRZ encoding with a
1200Mbaud bitrate, but should be driven with 1000BASE-X on the host
side.

Add a workaround for the detection of VSOL V2801F / CarlitoxxPro
CPGOS03-0490 v2.0 GPON module which CarlitoxxPro states needs single
byte I2C reads to the EEPROM.
Pali Rohár reports that he also has a CarlitoxxPro-based V2801F module,
which reports a manufacturer of "OEM". This manufacturer can't be
matched as it appears in many different modules, so also match the part
number too.

1. When the x25 module gets loaded, layer 2 may already be running and
connected. In this case, although we are in X25_LINK_STATE_0, we still
need to handle the Restart Request received, rather than ignore it.
2. When we are in X25_LINK_STATE_2, we have already sent a Restart Request
and is waiting for the Restart Confirmation with t20timer. t20timer will
restart itself repeatedly forever so it will always be there, as long as we
are in State 2. So we don't need to check x25_t20timer_pending again.

When the workqueue disposes of the msk, the subflows can still
receive some data from the peer after __mptcp_close_ssk()
completes.
The above could trigger a race between the msk receive path and the
msk destruction. Acquiring the mptcp_data_lock() in __mptcp_destroy_sock()
will not save the day: the rx path could be reached even after msk
destruction completes.
Instead use the subflow 'disposable' flag to prevent entering
the msk receive path after __mptcp_close_ssk().

When a MPTCP listener socket is closed with unaccepted
children pending, the ULP release callback will be invoked,
but nobody will call into __mptcp_close_ssk() on the
corresponding subflow.
As a consequence, at ULP release time, the 'disposable' flag
will be cleared and the subflow context memory will be leaked.
This change addresses the issue always freeing the context if
the subflow is still in the accept queue at ULP release time.
Additionally, this fixes an incorrect code reference in the
related comment.
Note: this fix leverages the changes introduced by the previous
commit.
