pKVM modules may need to enable fine grain traps. To allow this
use-case, expose a function allowing to manipulate HFGWTR_EL2 on the
current CPU. This configuration will be persistent across power
management cycles and such as it is propagated all the way to the

Add support to use a random local address in authentication and
deauthentication frames sent to unassociated peer when the driver
supports.
The driver needs to configure receive behavior to accept frames with
random transmit address specified in TX path authentication frames
during the time of the frame exchange is pending and such frames need to
be acknowledged similarly to frames sent to the local permanent address
when this random address functionality is used.
This capability allows use of randomized transmit address for PASN
authentication frames to improve privacy of WLAN clients.

The pKVM hypervisor uses the module_ops struct as a way to expose
services to loadable modules. It doesn't however allow fine-grained
definition of the license for each export, and doesn't have a way to
check the license of the loaded module (yet). As such, the assumption
is that said module is proprietary, and must NOT be allowed to use GPL
symbols.
Even though symbols such as __pkvm_load_el2_module are currently
exported as GPL, these exports only apply to the kernel part of the
module, which is usually only a proxy to load the hyp module, which
may be built separately.
Given the lack of license enforcement at load time, let's seek GPL
compliance by preventing the accidental export of GPL symbols to hyp
modules via pKVM's module_ops struct. To do so, add a build time check
for the absence of such symbols from the KVM nvhe code entirely.
In the future (Android 15+ and upstream), we should consider expanding
the pKVM module loader to allow finer grained licensing of exports.
This would allow exposing internal pKVM functions as GPL only for e.g.
selftests and such w/o risking exports to proprietary modules.

In one of the SMMU faults (NULL Pointer derefernce) the following

The events happened in order are as follows:
We got a setup packet for ffs interface and was passed to android
setup callback from ep0.c. As part of the delegate request, the
dwc->lock is released.
At this instant a composition switch occurred and as per traces
and crash dumps:
1. UDC Stop was done successfully. So run stop is set to '0'
2. Composite disconnect was done and ep disable for all ep's is done
gadget->connected = FALSE
3. Async callbacks disabled
dwc->aysnc_callbacks = FALSE
4. composite unbind is going on and the ffs interface in question is
unbinded
udc->driver != NULL
(as per crash dump indicating that unbind is in progress)
5. Purge configs was ongoing because as per crash dumps:
otg_desc[0] = NULL;
cdev->os_desc_req->buf is not NULL
(configfs_composite_unbind is going on, but composite_dev_cleanup
not yet done)
As per the traces:
23.794712: dwc3_event event=49216 ep0state=1 str=
23.794909: dwc3_ctrl_req bRequestType=161 bRequest=1 wValue=0
wIndex=2 wLength=4096
23.799740: usb_gadget_disconnect speed=5 max_speed=6 state=7
mA=0 deactivated=0 connected=0 ret=0
This indicated that android setup came first followed by composite
disconnect. Since the dwc->lock was released by delegate_request,
soft disconnect gets unblocked and runs parallel to composite setup.
After this, there is no check in path of composite setup
indicating unbind happened and bail out is necessary instead of
executing any function ops.
Protect composite_setup (as part of android_setup) in a spinlock
to block composite_disconnect/unbind running in parallel.
Moreover, in the configfs counterpart of android_setup (configfs_
composite_stetup), the composite_setup call is done with spinlock
held.
It is only the android_setup missing this lock.
