commit 6cd0fe9138 upstream.
When binding the ConfigFS gadget to a UDC, the functions in each
configuration are added in list order. However, if usb_add_function()
fails, the failed function is put back on its configuration's
func_list and purge_configs_funcs() is called to further clean up.
purge_configs_funcs() iterates over the configurations and functions
in forward order, calling unbind() on each of the previously added
functions. But after doing so, each function gets moved to the
tail of the configuration's func_list. This results in reshuffling
the original order of the functions within a configuration such
that the failed function now appears first even though it may have
originally appeared in the middle or even end of the list. At this
point if the ConfigFS gadget is attempted to re-bind to the UDC,
the functions will be added in a different order than intended,
with the only recourse being to remove and relink the functions all
over again.
An example of this as follows:
ln -s functions/mass_storage.0 configs/c.1
ln -s functions/ncm.0 configs/c.1
ln -s functions/ffs.adb configs/c.1 # oops, forgot to start adbd
echo "<udc device>" > UDC # fails
start adbd
echo "<udc device>" > UDC # now succeeds, but...
# bind order is
# "ADB", mass_storage, ncm

Fix this by reversing the iteration order of the functions in
purge_config_funcs() when unbinding them, and adding them back to
the config's func_list at the head instead of the tail. This
ensures that we unbind and unwind back to the original list order.

There is a spinlock lockup as part of composite_disconnect

This is because the usb_gadget_deactivate is called from
usb_function_deactivate with the same spinlock held.
This would result in the below call stack and leads to stall.

Fix this by doing an unlock on cdev->lock before the usb_gadget_deactivate
call from usb_function_deactivate.
The same lockup can happen in the usb_gadget_activate path. Fix that path
as well.

Fix the MTU size issue with RX packet size as the host sends the packet
with extra bytes containing ethernet header. This causes failure when
user sets the MTU size to the maximum i.e. 15412. In this case the
ethernet packet received will be of length 15412 plus the ethernet header
length. This patch fixes the issue where there is a check that RX packet
length must not be more than max packet length.

commit a353397b0d upstream.
In many cases a function that supports SuperSpeed can very well
operate in SuperSpeedPlus, if a gadget controller supports it,
as the endpoint descriptors (and companion descriptors) are
generally identical and can be re-used. This is true for two
commonly used functions: Android's ADB and MTP. So we can simply
assign the usb_function's ssp_descriptors array to point to its
ss_descriptors, if available. Similarly, we need to allow an
epfile's ioctl for FUNCTIONFS_ENDPOINT_DESC to correctly
return the corresponding SuperSpeed endpoint descriptor in case
the connected speed is SuperSpeedPlus as well.
The only exception is if a function wants to implement an
Isochronous endpoint capable of transferring more than 48KB per
service interval when operating at greater than USB 3.1 Gen1
speed, in which case it would require an additional SuperSpeedPlus
Isochronous Endpoint Companion descriptor to be returned as part
of the Configuration Descriptor. Support for that would need
to be separately added to the userspace-facing FunctionFS API
which may not be a trivial task--likely a new descriptor format
(v3?) may need to be devised to allow for separate SS and SSP
descriptors to be supplied.

and ioremap(). goku_remove() gets a device from
pci_get_drvdata(pdev) and works with it without any checks, in
particular it dereferences a corresponding pointer. But
goku_probe() did not set this device yet. So, one can expect
various crashes. The patch moves setting the device just after
allocation of memory for it.

[ Upstream commit 7974ecd7d3 ]
Currently, enabling f_ncm at SuperSpeed Plus speeds results in an
oops in config_ep_by_speed because ncm_set_alt passes in NULL
ssp_descriptors. Fix this by re-using the SuperSpeed descriptors.
This is safe because usb_assign_descriptors calls
usb_copy_descriptors.
Tested: enabled f_ncm on a dwc3 gadget and 10Gbps link, ran iperf

[ Upstream commit 4eea21dc67 ]
The u_ether driver has a qmult setting that multiplies the
transmit queue length (which by default is 2).
The intent is that it should be enabled at high/super speed, but
because the code does not explicitly check for USB_SUPER_PLUS,
it is disabled at that speed.
Fix this by ensuring that the queue multiplier is enabled for any
wired link at high speed or above. Using >= for USB_SPEED_*
constants seems correct because it is what the gadget_is_xxxspeed
functions do.
The queue multiplier substantially helps performance at higher
speeds. On a direct SuperSpeed Plus link to a Linux laptop,
iperf3 single TCP stream:

[ Upstream commit 986499b156 ]
Currently, SuperSpeed NCM gadgets report a speed of 851 Mbps
in USB_CDC_NOTIFY_SPEED_CHANGE. But the calculation appears to
assume 16 packets per microframe, and USB 3 and above no longer
use microframes.
Maximum speed is actually much higher. On a direct connection,
theoretical throughput is at most 3.86 Gbps for gen1x1 and
9.36 Gbps for gen2x1, and I have seen gadget->host iperf
throughput of >2 Gbps for gen1x1 and >4 Gbps for gen2x1.
Unfortunately the ConnectionSpeedChange defined in the CDC spec
only uses 32-bit values, so we can't report accurate numbers for
10Gbps and above. So, report 3.75Gbps for SuperSpeed (which is
roughly maximum theoretical performance) and 4.25Gbps for
SuperSpeed Plus (which is close to the maximum that we can report
in a 32-bit unsigned integer).
This results in:

commit 2b405533c2 upstream.
commit 2b74b0a04d ("USB: gadget: f_ncm: add bounds checks to ncm_unwrap_ntb()")
adds important bounds checking however it unfortunately also introduces a
bug with respect to section 3.3.1 of the NCM specification.
wDatagramIndex[1] : "Byte index, in little endian, of the second datagram
described by this NDP16. If zero, then this marks the end of the sequence
of datagrams in this NDP16."
wDatagramLength[1]: "Byte length, in little endian, of the second datagram
described by this NDP16. If zero, then this marks the end of the sequence
of datagrams in this NDP16."
wDatagramIndex[1] and wDatagramLength[1] respectively then may be zero but
that does not mean we should throw away the data referenced by
wDatagramIndex[0] and wDatagramLength[0] as is currently the case.
Breaking the loop on (index2 == 0 || dg_len2 == 0) should come at the end
as was previously the case and checks for index2 and dg_len2 should be
removed since zero is valid.
I'm not sure how much testing the above patch received but for me right now
after enumeration ping doesn't work. Reverting the commit restores ping,
scp, etc.
The extra validation associated with wDatagramIndex[0] and
wDatagramLength[0] appears to be valid so, this change removes the incorrect
restriction on wDatagramIndex[1] and wDatagramLength[1] restoring data
processing between host and device.

To fix this, add a test for saturation before declaring variables and an

If the expression results in overflow, vla_group_size() will return SIZE_MAX.

This patch adds new config_ep_by_speed_and_alt function which
extends the config_ep_by_speed about alt parameter.
This additional parameter allows to find proper usb_ss_ep_comp_descriptor.
Problem has appeared during testing f_tcm (BOT/UAS) driver function.
f_tcm function for SS use array of headers for both BOT/UAS alternate
setting:
static struct usb_descriptor_header *uasp_ss_function_desc[] = {
(struct usb_descriptor_header *) &bot_intf_desc,
(struct usb_descriptor_header *) &uasp_ss_bi_desc,
(struct usb_descriptor_header *) &bot_bi_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_ss_bo_desc,
(struct usb_descriptor_header *) &bot_bo_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_intf_desc,
(struct usb_descriptor_header *) &uasp_ss_bi_desc,
(struct usb_descriptor_header *) &uasp_bi_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_bi_pipe_desc,
(struct usb_descriptor_header *) &uasp_ss_bo_desc,
(struct usb_descriptor_header *) &uasp_bo_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_bo_pipe_desc,
(struct usb_descriptor_header *) &uasp_ss_status_desc,
(struct usb_descriptor_header *) &uasp_status_in_ep_comp_desc,
(struct usb_descriptor_header *) &uasp_status_pipe_desc,
(struct usb_descriptor_header *) &uasp_ss_cmd_desc,
(struct usb_descriptor_header *) &uasp_cmd_comp_desc,
(struct usb_descriptor_header *) &uasp_cmd_pipe_desc,
NULL,
};
The first 5 descriptors are associated with BOT alternate setting,
and others are associated with UAS.
During handling UAS alternate setting f_tcm driver invokes
config_ep_by_speed and this function sets incorrect companion endpoint
descriptor in usb_ep object.
Instead setting ep->comp_desc to uasp_bi_ep_comp_desc function in this
case set ep->comp_desc to uasp_ss_bi_desc.
This is due to the fact that it searches endpoint based on endpoint
address:
for_each_ep_desc(speed_desc, d_spd) {
chosen_desc = (struct usb_endpoint_descriptor *)*d_spd;
if (chosen_desc->bEndpoitAddress == _ep->address)
goto ep_found;
}
And in result it uses the descriptor from BOT alternate setting
instead UAS.
Finally, it causes that controller driver during enabling endpoints
detect that just enabled endpoint for bot.

It is not wrong, queue is not a pointer so if ep is not NULL, the

[ Upstream commit 3c73bc5219 ]
The threaded interrupt handler may still be called after the
usb_gadget_disconnect is called, it causes the structures used
at interrupt handler was freed before it uses, eg the
usb_request. This issue usually occurs we remove the udc function
during the transfer. Below is the example when doing stress
test for android switch function, the EP0's request is freed
by .unbind (configfs_composite_unbind -> composite_dev_cleanup),
but the threaded handler accesses this request during handling
setup packet request.
In fact, there is no protection between unbind the udc
and udc interrupt handling, so we have to avoid the interrupt
handler is occurred or scheduled during the .unbind flow.
