commit b65ba0c362be665192381cc59e3ac3ef6f0dd1e1 upstream.
In commit 92af4fc6ec33 ("usb: musb: Fix suspend with devices
connected for a64"), the logic to support the
MUSB_QUIRK_B_DISCONNECT_99 quirk was modified to only conditionally
schedule the musb->irq_work delayed work.
This commit badly breaks ECM Gadget on AM335X. Indeed, with this
commit, one can observe massive packet loss:
$ ping 192.168.0.100
...
15 packets transmitted, 3 received, 80% packet loss, time 14316ms
Reverting this commit brings back a properly functioning ECM
Gadget. An analysis of the commit seems to indicate that a mistake was
made: the previous code was not falling through into the
MUSB_QUIRK_B_INVALID_VBUS_91, but now it is, unless the condition is
taken.
Changing the logic to be as it was before the problematic commit *and*
only conditionally scheduling musb->irq_work resolves the regression:
$ ping 192.168.0.100
...
64 packets transmitted, 64 received, 0% packet loss, time 64475ms

commit d00889080ab60051627dab1d85831cd9db750e2a upstream.
There is no validation of the index from dwc3_wIndex_to_dep() and we might
be referring a non-existing ep and trigger a NULL pointer exception. In
certain configurations we might use fewer eps and the index might wrongly
indicate a larger ep index than existing.
By adding this validation from the patch we can actually report a wrong
index back to the caller.
In our usecase we are using a composite device on an older kernel, but
upstream might use this fix also. Unfortunately, I cannot describe the
hardware for others to reproduce the issue as it is a proprietary
implementation.

commit 03715ea2e3dbbc56947137ce3b4ac18a726b2f87 upstream.
There exists a possible scenario in which dwc3_gadget_init() can fail:
during during host -> peripheral mode switch in dwc3_set_mode(), and
a pending gadget driver fails to bind. Then, if the DRD undergoes
another mode switch from peripheral->host the resulting
dwc3_gadget_exit() will attempt to reference an invalid and dangling
dwc->gadget pointer as well as call dma_free_coherent() on unmapped
DMA pointers.
The exact scenario can be reproduced as follows:
- Start DWC3 in peripheral mode
- Configure ConfigFS gadget with FunctionFS instance (or use g_ffs)
- Run FunctionFS userspace application (open EPs, write descriptors, etc)
- Bind gadget driver to DWC3's UDC
- Switch DWC3 to host mode
=> dwc3_gadget_exit() is called. usb_del_gadget() will put the
ConfigFS driver instance on the gadget_driver_pending_list
- Stop FunctionFS application (closes the ep files)
- Switch DWC3 to peripheral mode
=> dwc3_gadget_init() fails as usb_add_gadget() calls
check_pending_gadget_drivers() and attempts to rebind the UDC
to the ConfigFS gadget but fails with -19 (-ENODEV) because the
FFS instance is not in FFS_ACTIVE state (userspace has not
re-opened and written the descriptors yet, i.e. desc_ready!=0).
- Switch DWC3 back to host mode
=> dwc3_gadget_exit() is called again, but this time dwc->gadget
is invalid.
Although it can be argued that userspace should take responsibility
for ensuring that the FunctionFS application be ready prior to
allowing the composite driver bind to the UDC, failure to do so
should not result in a panic from the kernel driver.
Fix this by setting dwc->gadget to NULL in the failure path of
dwc3_gadget_init() and add a check to dwc3_gadget_exit() to bail out
unless the gadget pointer is valid.

the probe
commit 1d0d3d818eafe1963ec1eaf302175cd14938188e upstream.
If an error occurs after a successful 'regulator_enable()' call,
'regulator_disable()' must be called.
Fix the error handling path of the probe accordingly.
The remove function doesn't need to be fixed, because the
'regulator_disable()' call is already hidden in 'dwc3_meson_g12a_suspend()'
which is called via 'pm_runtime_set_suspended()' in the remove function.

commit 1958ff5ad2d4908b44a72bcf564dfe67c981e7fe upstream.
The reasoning for this change is that if we already had
a packet pending, then we also already had a pending timer,
and as such there is no need to reschedule it.
This also prevents packets getting delayed 60 ms worst case
under a tiny packet every 290us transmit load, by keeping the
timeout always relative to the first queued up packet.
(300us delay * 16KB max aggregation / 80 byte packet =~ 60 ms)
As such the first packet is now at most delayed by 300us.
Under low transmit load, this will simply result in us sending
a shorter aggregate, as originally intended.
This patch has the benefit of greatly reducing (by ~10 factor
with 1500 byte frames aggregated into 16 kiB) the number of
(potentially pretty costly) updates to the hrtimer.

commit acf5631c239dfc53489f739c4ad47f490c5181ff upstream.
In typec_mux_match() "nval" is assigned the number of elements in the
"svid" fwnode property, then the variable is used to store the success
of the read and finally attempts to loop between 0 and "success" - i.e.
not at all - and the code returns indicating that no match was found.
Fix this by using a separate variable to track the success of the read,
to allow the loop to get a change to find a match.

commit e752dbc59e1241b13b8c4f7b6eb582862e7668fe upstream.
The usb3_start_pipen() is called by renesas_usb3_ep_queue() and
usb3_request_done_pipen() so that usb3_start_pipen() is possible
to cause a race when getting usb3_first_req like below:

usb3_first_req = usb3_get_request()
...
(the req is possible to be finished in the interrupt)
The usb3_first_req [1] above may have been finished after the interrupt
ended so that this driver caused to start a transfer wrongly. To fix this
issue, getting/checking the usb3_first_req are under spin_lock_irqsave()

commit 25dda9fc56bd90d45f9a4516bcfa5211e61b4290 upstream.
The driver incorrectly uses req->num_pending_sgs to track both the
number of pending and queued SG entries. It only prepares the next

until there is TRB completion interrupt. This may starve the controller
of more TRBs until the num_pending_sgs is decremented.
Fix this by decrementing the num_pending_sgs after they are queued and
properly track both num_mapped_sgs and num_queued_sgs.

commit 4f2629ea67e7225c3fd292c7fe4f5b3c9d6392de upstream.
Syzbot found that the kernel generates a WARNing if the user tries to
submit a bulk transfer through usbfs with a buffer that is way too
large. This isn't a bug in the kernel; it's merely an invalid request
from the user and the usbfs code does handle it correctly.
In theory the same thing can happen with async transfers, or with the
packet descriptor table for isochronous transfers.
To prevent the MM subsystem from complaining about these bad
allocation requests, add the __GFP_NOWARN flag to the kmalloc calls
for these buffers.

'xhci_urb_enqueue()', uses GFP_KERNEL.

commit 1f4642b72be79757f050924a9b9673b6a02034bc upstream.
commit 4dbc6a4ef06d ("usb: typec: ucsi: save power data objects
in PD mode") introduced retrieval of the PDOs when connected to a
PD-capable source. But only the first 4 PDOs are received since
that is the maximum number that can be fetched at a time given the
MESSAGE_IN length limitation (16 bytes). However, as per the PD spec
a connected source may advertise up to a maximum of 7 PDOs.
If such a source is connected it's possible the PPM could have
negotiated a power contract with one of the PDOs at index greater
than 4, and would be reflected in the request data object's (RDO)
object position field. This would result in an out-of-bounds access
when the rdo_index() is used to index into the src_pdos array in
ucsi_psy_get_voltage_now().
With the help of the UBSAN -fsanitize=array-bounds checker enabled
this exact issue is revealed when connecting to a PD source adapter
that advertise 5 PDOs and the PPM enters a contract having selected
the 5th one.

commit 75a41ce46bae6cbe7d3bb2584eb844291d642874 upstream.
The dwc2 gadget support maps and unmaps DMA buffers as necessary. When
mapping and unmapping it uses the direction of the endpoint to select
the direction of the DMA transfer, but this fails for Control OUT
transfers because the unmap occurs after the endpoint direction has
been reversed for the status phase.
A possible solution would be to unmap the buffer before the direction
is changed, but a safer, less invasive fix is to remember the buffer
direction independently of the endpoint direction.

commit e17b02d4970913233d543c79c9c66e72cac05bdd upstream.
When extcon is used in combination with dwc3, it is assumed that the dwc3
registers are untouched and as such are only configured if VBUS is valid
or ID is tied to ground.
In case VBUS is not valid or ID is floating, the registers are not
configured as such during driver initialization, causing a wrong
default state during boot.
If the registers are not in a default state, because they are for
instance touched by a boot loader, this can cause for a kernel error.

[ Upstream commit bb9c74a5bd1462499fe5ccb1e3c5ac40dcfa9139 ]
As part of commit e81a7018d93a ("usb: dwc3: allocate gadget structure
dynamically") the dwc3_gadget_release() was added which will free
the dwc->gadget structure upon the device's removal when
usb_del_gadget_udc() is called in dwc3_gadget_exit().
However, simply freeing the gadget results a dangling pointer
situation: the endpoints created in dwc3_gadget_init_endpoints()
have their dep->endpoint.ep_list members chained off the list_head
anchored at dwc->gadget->ep_list. Thus when dwc->gadget is freed,
the first dwc3_ep in the list now has a dangling prev pointer and
likewise for the next pointer of the dwc3_ep at the tail of the list.
The dwc3_gadget_free_endpoints() that follows will result in a
use-after-free when it calls list_del().
This was caught by enabling KASAN and performing a driver unbind.
The recent commit 568262bf5492 ("usb: dwc3: core: Add shutdown
callback for dwc3") also exposes this as a panic during shutdown.
There are a few possibilities to fix this. One could be to perform
a list_del() of the gadget->ep_list itself which removes it from
the rest of the dwc3_ep chain.
Another approach is what this patch does, by splitting up the
usb_del_gadget_udc() call into its separate "del" and "put"
components. This allows dwc3_gadget_free_endpoints() to be
called before the gadget is finally freed with usb_put_gadget().

[ Upstream commit 24d209dba5a3959b2ebde7cf3ad40c8015e814cf ]
When core is in hibernation in host mode and a device cable
was connected then driver exited from device hibernation.
However, registers saved for host mode and when exited from
device hibernation register restore would be done for device
register which was wrong because there was no device registers
stored to restore.
- Added dwc_handle_gpwrdn_disc_det() function which handles
gpwrdn disconnect detect flow and exits hibernation
without restoring the registers.
- Updated exiting from hibernation in GPWRDN_STS_CHGINT with
calling dwc_handle_gpwrdn_disc_det() function. Here no register
is restored which is the solution described above.
Fixes: 65c9c4c6b01f ("usb: dwc2: Add dwc2_handle_gpwrdn_intr() handler")
