When we set up a TDLS station, we set sta->sta.bandwidth solely based

This leads to the unfortunate scenario that the sta->sta.bandwidth is
160 MHz if both stations support it, but we never actually configure
this bandwidth unless the AP is already using 160 MHz; even for wider
bandwidth support we only go up to 80 MHz (at least right now.)
For iwlwifi, this can also lead to firmware asserts, telling us that
we've configured the TX rates for a higher bandwidth than is actually
available due to the PHY configuration.
For non-TDLS, we check against the interface's requested bandwidth,
but we explicitly skip this check for TDLS to cope with the wider BW
case. Change this to
(a) still limit to the TDLS peer's own chandef, which gets factored
into the overall PHY configuration we request from the driver,

factored into the channel context in this case.

cfg80211: fix callback type mismatches in wext-compat
Instead of casting callback functions to type iw_handler, which trips
indirect call checking with Clang's Control-Flow Integrity (CFI), add
stub functions with the correct function type for the callbacks.
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

selftests/bpf: Silence ima_setup.sh when not running in verbose mode.
Currently, ima_setup.sh spews outputs from commands like mkfs and dd
on the terminal without taking into account the verbosity level of
the test framework. Update test_progs to set the environment variable
SELFTESTS_VERBOSE=1 when a verbose output is requested. This
environment variable is then used by ima_setup.sh (and can be used by
other similar scripts) to obey the verbosity level of the test harness
without needing to re-implement command line options for verbosity.
In "silent" mode, the script saves the output to a temporary file, the
contents of which are echoed back to stderr when the script encounters
an error.
LLC is meant for compiler development and debugging. Consequently, it
exposes many low level options about its backend. To avoid future bugs
introduced by using the raw LLC tool, use clang directly so that all
appropriate options are passed to the back end.
Additionally, simplify the Makefile by removing the
CLANG_NATIVE_BPF_BUILD_RULE as it is not being use, stop passing
dwarfris attr since elfutils/libdw now supports the bpf backend (which
should work with any recent pahole), and stop passing alu32 since
-mcpu=v3 implies alu32.
bpf_testmod.ko build rule declared dependency on VMLINUX_BTF, but the variable
itself was initialized after the rule was declared, which often caused
bpf_testmod.ko to not be re-compiled. Fix by moving VMLINUX_BTF determination
sooner.
Also enforce bpf_testmod.ko recompilation when we detect that vmlinux image
changed by removing bpf_testmod/bpf_testmod.ko. This is necessary to generate
correct module's split BTF. Without it, Kbuild's module build logic might
determine that nothing changed on the kernel side and thus bpf_testmod.ko
shouldn't be rebuilt, so won't re-generate module BTF, which often leads to
module's BTF with wrong string offsets against vmlinux BTF. Removing .ko file
forces Kbuild to re-build the module.

====================
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.
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 [email protected]
* 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.

ppp: add PPPIOCBRIDGECHAN and PPPIOCUNBRIDGECHAN ioctls
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.

NFS: Fix rpcrdma_inline_fixup() crash with new LISTXATTRS operation
By switching to an XFS-backed export, I am able to reproduce the
ibcomp worker crash on my client with xfstests generic/013.
For the failing LISTXATTRS operation, xdr_inline_pages() is called
with page_len=12 and buflen=128.
- When ->send_request() is called, rpcrdma_marshal_req() does not
set up a Reply chunk because buflen is smaller than the inline
threshold. Thus rpcrdma_convert_iovs() does not get invoked at
all and the transport's XDRBUF_SPARSE_PAGES logic is not invoked
on the receive buffer.
- During reply processing, rpcrdma_inline_fixup() tries to copy
received data into rq_rcv_buf->pages because page_len is positive.
But there are no receive pages because rpcrdma_marshal_req() never
allocated them.
The result is that the ibcomp worker faults and dies. Sometimes that
causes a visible crash, and sometimes it results in a transport hang
without other symptoms.
RPC/RDMA's XDRBUF_SPARSE_PAGES support is not entirely correct, and
should eventually be fixed or replaced. However, my preference is
that upper-layer operations should explicitly allocate their receive
buffers (using GFP_KERNEL) when possible, rather than relying on
XDRBUF_SPARSE_PAGES.
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.

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

After a 32-bit load followed by a branch, the verifier would reduce the
maximum bound of the register to 0x7fffffff, allowing a user to bypass
bound checks. Ensure such a program is rejected.
In the second test, the 64-bit compare should not sufficient to
determine whether the signed 32-bit lower bound is 0, so the verifier
should reject the second branch.
A prior patch increased the size of struct tcp_zerocopy_receive
but did not update do_tcp_getsockopt() handling to properly account
for this.
This patch simply reintroduces content erroneously cut from the

The 64-bit signed bounds should not affect 32-bit signed bounds unless the

register with smin_value==1 doesn't mean that s32_min_value is also equal to 1,
since smax_value could be larger than 32-bit subregister can hold.
The verifier refines the smax/s32_max return value from certain helpers in
do_refine_retval_range(). Teach the verifier to recognize that smin/s32_min
value is also bounded. When both smin and smax bounds fit into 32-bit
subregister the verifier can propagate those bounds.
