USB: Add NO_LPM quirk for Kingston flash drive
commit afaa2e745a246c5ab95103a65b1ed00101e1bc63 upstream. In Bugzilla #208257, Julien Humbert reports that a 32-GB Kingston flash drive spontaneously disconnects and reconnects, over and over. Testing revealed that disabling Link Power Management for the drive fixed the problem. This patch adds a quirk entry for that drive to turn off LPM permanently.

USB: serial: cyberjack: fix write-URB completion race
commit 985616f0457d9f555fff417d0da56174f70cc14f upstream.
The write-URB busy flag was being cleared before the completion handler
was done with the URB, something which could lead to corrupt transfers
due to a racing write request if the URB is resubmitted.

usb: typec: tcpm: reset hard_reset_count for any disconnect
commit 2d9c6442a9c81f4f8dee678d0b3c183173ab1e2d upstream.
Current tcpm_detach() only reset hard_reset_count if port->attached
is true, this may cause this counter clear is missed if the CC
disconnect event is generated after tcpm_port_reset() is done
by other events, e.g. VBUS off comes first before CC disconect for
a power sink, in that case the first tcpm_detach() will only clear
port->attached flag but leave hard_reset_count there because
tcpm_port_is_disconnected() is still false, then later tcpm_detach()
by CC disconnect will directly return due to port->attached is cleared,
finally this will result tcpm will not try hard reset or error recovery
for later attach.
ChiYuan reported this issue on his platform with below tcpm trace:
After power sink session setup after hard reset 2 times, detach
from the power source and then attach:

usb: cdc-acm: fix cooldown mechanism
commit 38203b8385bf6283537162bde7d499f830964711 upstream.
Commit a4e7279cd1d1 ("cdc-acm: introduce a cool down") is causing
regression if there is some USB error, such as -EPROTO.
This has been reported on some samples of the Odroid-N2 using the Combee II
Zibgee USB dongle.
> struct acm *acm = container_of(work, struct acm, work)
is incorrect in case of a delayed work and causes warnings, usually from
the workqueue:
> WARNING: CPU: 0 PID: 0 at kernel/workqueue.c:1474 __queue_work+0x480/0x528.
When this happens, USB eventually stops working completely after a while.
Also the ACM_ERROR_DELAY bit is never set, so the cooldown mechanism
previously introduced cannot be triggered and acm_submit_read_urb() is
never called.
This changes makes the cdc-acm driver use a single delayed work, fixing the
pointer arithmetic in acm_softint() and set the ACM_ERROR_DELAY when the
cooldown mechanism appear to be needed.

usb: dwc3: ep0: Fix ZLP for OUT ep0 requests
commit 66706077dc89c66a4777a4c6298273816afb848c upstream. The current ZLP handling for ep0 requests is only for control IN requests. For OUT direction, DWC3 needs to check and setup for MPS alignment. Usually, control OUT requests can indicate its transfer size via the wLength field of the control message. So usb_request->zero is usually not needed for OUT direction. To handle ZLP OUT for control endpoint, make sure the TRB is MPS size. Cc: stable@vger.kernel.org Fixes: |

usb: xhci: omit duplicate actions when suspending a runtime suspended host.
[ Upstream commit 18a367e8947d72dd91b6fc401e88a2952c6363f7 ] If the xhci-plat.c is the platform driver, after the runtime pm is enabled, the xhci_suspend is called if nothing is connected on the port. When the system goes to suspend, it will call xhci_suspend again if USB wakeup is enabled. Since the runtime suspend wakeup setting is not always the same as system suspend wakeup setting, eg, at runtime suspend we always need wakeup if the controller is in low power mode; but at system suspend, we may not need wakeup. So, we move the judgement after changing wakeup setting.

usb: typec: tcpm: During PR_SWAP, source caps should be sent only after tSwapSourceStart
[ Upstream commit 6bbe2a90a0bb4af8dd99c3565e907fe9b5e7fd88 ] The patch addresses the compliance test failures while running TD.PD.CP.E3, TD.PD.CP.E4, TD.PD.CP.E5 of the "Deterministic PD Compliance MOI" test plan published in https://www.usb.org/usbc. For a product to be Type-C compliant, it's expected that these tests are run on usb.org certified Type-C compliance tester as mentioned in https://www.usb.org/usbc. The purpose of the tests TD.PD.CP.E3, TD.PD.CP.E4, TD.PD.CP.E5 is to verify the PR_SWAP response of the device. While doing so, the test asserts that Source Capabilities message is NOT received from the test device within tSwapSourceStart min (20 ms) from the time the last bit of GoodCRC corresponding to the RS_RDY message sent by the UUT was sent. If it does then the test fails. This is in line with the requirements from the USB Power Delivery Specification Revision 3.0, Version 1.2: "6.6.8.1 SwapSourceStartTimer The SwapSourceStartTimer Shall be used by the new Source, after a Power Role Swap or Fast Role Swap, to ensure that it does not send Source_Capabilities Message before the new Sink is ready to receive the Source_Capabilities Message. The new Source Shall Not send the Source_Capabilities Message earlier than tSwapSourceStart after the last bit of the EOP of GoodCRC Message sent in response to the PS_RDY Message sent by the new Source indicating that its power supply is ready." The patch makes sure that TCPM does not send the Source_Capabilities Message within tSwapSourceStart(20ms) by transitioning into SRC_STARTUP only after tSwapSourceStart(20ms).

[ Upstream commit 7974ecd7d3c0f42a98566f281e44ea8573a2ad88 ] 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.

USB: cdc-wdm: Make wdm_flush() interruptible and add wdm_fsync().
commit 37d2a36394d954413a495da61da1b2a51ecd28ab upstream. syzbot is reporting hung task at wdm_flush() [1], for there is a circular dependency that wdm_flush() from flip_close() for /dev/cdc-wdm0 forever waits for /dev/raw-gadget to be closed while close() for /dev/raw-gadget cannot be called unless close() for /dev/cdc-wdm0 completes. Tetsuo Handa considered that such circular dependency is an usage error [2] which corresponds to an unresponding broken hardware [3]. But Alan Stern responded that we should be prepared for such hardware [4]. Therefore, this patch changes wdm_flush() to use wait_event_interruptible_timeout() which gives up after 30 seconds, for hardware that remains silent must be ignored. The 30 seconds are coming out of thin air. Changing wait_event() to wait_event_interruptible_timeout() makes error reporting from close() syscall less reliable. To compensate it, this patch also implements wdm_fsync() which does not use timeout. Those who want to be very sure that data has gone out to the device are now advised to call fsync(), with a caveat that fsync() can return -EINVAL when running on older kernels which do not implement wdm_fsync(). This patch also fixes three more problems (listed below) found during exhaustive discussion and testing. Since multiple threads can concurrently call wdm_write()/wdm_flush(), we need to use wake_up_all() whenever clearing WDM_IN_USE in order to make sure that all waiters are woken up. Also, error reporting needs to use fetch-and-clear approach in order not to report same error for multiple times. Since wdm_flush() checks WDM_DISCONNECTING, wdm_write() should as well check WDM_DISCONNECTING. In wdm_flush(), since locks are not held, it is not safe to dereference desc->intf after checking that WDM_DISCONNECTING is not set [5]. Thus, remove dev_err() from wdm_flush().

usb: cdc-acm: add quirk to blacklist ETAS ES58X devices
commit a4f88430af896bf34ec25a7a5f0e053fb3d928e0 upstream.
The ES58X devices has a CDC ACM interface (used for debug
purpose). During probing, the device is thus recognized as USB Modem
(CDC ACM), preventing the etas-es58x module to load:
usbcore: registered new interface driver etas_es58x
usb 1-1.1: new full-speed USB device number 14 using xhci_hcd
usb 1-1.1: New USB device found, idVendor=108c, idProduct=0159, bcdDevice= 1.00
usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.1: Product: ES581.4
usb 1-1.1: Manufacturer: ETAS GmbH
usb 1-1.1: SerialNumber: 2204355
cdc_acm 1-1.1:1.0: No union descriptor, testing for castrated device
cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device
Thus, these have been added to the ignore list in
drivers/usb/class/cdc-acm.c
N.B. Future firmware release of the ES58X will remove the CDC-ACM
interface.

usb: core: Solve race condition in anchor cleanup functions
[ Upstream commit fbc299437c06648afcc7891e6e2e6638dd48d4df ]
usb_kill_anchored_urbs() is commonly used to cancel all URBs on an
anchor just before releasing resources which the URBs rely on. By doing
so, users of this function rely on that no completer callbacks will take
place from any URB on the anchor after it returns.
However if this function is called in parallel with __usb_hcd_giveback_urb
processing a URB on the anchor, the latter may call the completer
callback after usb_kill_anchored_urbs() returns. This can lead to a
kernel panic due to use after release of memory in interrupt context.
The race condition is that __usb_hcd_giveback_urb() first unanchors the URB
and then makes the completer callback. Such URB is hence invisible to
usb_kill_anchored_urbs(), allowing it to return before the completer has
been called, since the anchor's urb_list is empty.
Even worse, if the racing completer callback resubmits the URB, it may
remain in the system long after usb_kill_anchored_urbs() returns.
Hence list_empty(&anchor->urb_list), which is used in the existing
while-loop, doesn't reliably ensure that all URBs of the anchor are gone.
A similar problem exists with usb_poison_anchored_urbs() and
usb_scuttle_anchored_urbs().
This patch adds an external do-while loop, which ensures that all URBs
are indeed handled before these three functions return. This change has
no effect at all unless the race condition occurs, in which case the
loop will busy-wait until the racing completer callback has finished.
This is a rare condition, so the CPU waste of this spinning is
negligible.
The additional do-while loop relies on usb_anchor_check_wakeup(), which
returns true iff the anchor list is empty, and there is no
__usb_hcd_giveback_urb() in the system that is in the middle of the
unanchor-before-complete phase. The @suspend_wakeups member of
struct usb_anchor is used for this purpose, which was introduced to solve
another problem which the same race condition causes, in commit

usb: ohci: Default to per-port over-current protection
[ Upstream commit b77d2a0a223bc139ee8904991b2922d215d02636 ] Some integrated OHCI controller hubs do not expose all ports of the hub to pins on the SoC. In some cases the unconnected ports generate spurious over-current events. For example the Broadcom 56060/Ranger 2 SoC contains a nominally 3 port hub but only the first port is wired. Default behaviour for ohci-platform driver is to use global over-current protection mode (AKA "ganged"). This leads to the spurious over-current events affecting all ports in the hub. We now alter the default to use per-port over-current protection. This patch results in the following configuration changes depending on quirks: - For quirk OHCI_QUIRK_SUPERIO no changes. These systems remain set up for ganged power switching and no over-current protection. - For quirk OHCI_QUIRK_AMD756 or OHCI_QUIRK_HUB_POWER power switching remains at none, while over-current protection is now guaranteed to be set to per-port rather than the previous behaviour where it was either none or global over-current protection depending on the value at function entry.

usb: dwc2: Fix INTR OUT transfers in DDMA mode.
[ Upstream commit b2c586eb07efab982419f32b7c3bd96829bc8bcd ] In DDMA mode if INTR OUT transfers mps not multiple of 4 then single packet corresponds to single descriptor. Descriptor limit set to mps and desc chain limit set to mps * MAX_DMA_DESC_NUM_GENERIC. On that descriptors complete, to calculate transfer size should be considered correction value for each descriptor. In start request function, if "continue" is true then dma buffer address should be incremmented by offset for all type of transfers, not only for Control DATA_OUT transfers. Fixes: |

usb: gadget: u_ether: enable qmult on SuperSpeed Plus as well
[ Upstream commit 4eea21dc67b0c6ba15ae41b1defa113a680a858e ]
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:
Before (qmult=1): 1.3 Gbps
After (qmult=5): 3.2 Gbps

usb: gadget: f_ncm: fix ncm_bitrate for SuperSpeed and above.
[ Upstream commit 986499b1569af980a819817f17238015b27793f6 ]
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:

is the target, which has a parameter of type 'struct dwc2_hsotg *',
but it is being implicitly cast to have a parameter of type 'void *'
because that is the set_params function pointer prototype. Make the
function pointer protoype match the definitions so that there is no
more violation.

USB: serial: ftdi_sio: add support for FreeCalypso JTAG+UART adapters
commit 6cf87e5edd9944e1d3b6efd966ea401effc304ee upstream. There exist many FT2232-based JTAG+UART adapter designs in which FT2232 Channel A is used for JTAG and Channel B is used for UART. The best way to handle them in Linux is to have the ftdi_sio driver create a ttyUSB device only for Channel B and not for Channel A: a ttyUSB device for Channel A would be bogus and will disappear as soon as the user runs OpenOCD or other applications that access Channel A for JTAG from userspace, causing undesirable noise for users. The ftdi_sio driver already has a dedicated quirk for such JTAG+UART FT2232 adapters, and it requires assigning custom USB IDs to such adapters and adding these IDs to the driver with the ftdi_jtag_quirk applied. Boutique hardware manufacturer Falconia Partners LLC has created a couple of JTAG+UART adapter designs (one buffered, one unbuffered) as part of FreeCalypso project, and this hardware is specifically made to be used with Linux hosts, with the intent that Channel A will be accessed only from userspace via appropriate applications, and that Channel B will be supported by the ftdi_sio kernel driver, presenting a standard ttyUSB device to userspace. Toward this end the hardware manufacturer will be programming FT2232 EEPROMs with custom USB IDs, specifically with the intent that these IDs will be recognized by the ftdi_sio driver with the ftdi_jtag_quirk applied.

USB: gadget: f_ncm: Fix NDP16 datagram validation
commit 2b405533c2560d7878199c57d95a39151351df72 upstream.
commit 2b74b0a04d3e ("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.

USB: EHCI: ehci-mv: fix less than zero comparison of an unsigned int
[ Upstream commit a7f40c233a6b0540d28743267560df9cfb571ca9 ]
The comparison of hcd->irq to less than zero for an error check will
never be true because hcd->irq is an unsigned int. Fix this by
assigning the int retval to the return of platform_get_irq and checking

USB: EHCI: ehci-mv: fix error handling in mv_ehci_probe()
[ Upstream commit c856b4b0fdb5044bca4c0acf9a66f3b5cc01a37a ] If the function platform_get_irq() failed, the negative value returned will not be detected here. So fix error handling in mv_ehci_probe(). And when get irq failed, the function platform_get_irq() logs an error message, so remove redundant message here.

ehci-hcd: Move include to keep CRC stable
commit 29231826f3bd65500118c473fccf31c0cf14dbc0 upstream.
The CRC calculation done by genksyms is triggered when the parser hits
EXPORT_SYMBOL*() macros. At this point, genksyms recursively expands the
types of the function parameters, and uses that as the input for the CRC
calculation. In the case of forward-declared structs, the type expands
to 'UNKNOWN'. Following this, it appears that the result of the
expansion of each type is cached somewhere, and seems to be re-used
when/if the same type is seen again for another exported symbol in the
same C file.
Unfortunately, this can cause CRC 'stability' issues when a struct
definition becomes visible in the middle of a C file. For example, let's
assume code with the following pattern:
struct foo;
int bar(struct foo *arg)
{
/* Do work ... */
}
EXPORT_SYMBOL_GPL(bar);
/* This contains struct foo's definition */
#include "foo.h"
int baz(struct foo *arg)
{
/* Do more work ... */
}
EXPORT_SYMBOL_GPL(baz);
Here, baz's CRC will be computed using the expansion of struct foo that
was cached after bar's CRC calculation ('UNKOWN' here). But if
EXPORT_SYMBOL_GPL(bar) is removed from the file (because of e.g. symbol
trimming using CONFIG_TRIM_UNUSED_KSYMS), struct foo will be expanded
late, during baz's CRC calculation, which now has visibility over the
full struct definition, hence resulting in a different CRC for baz.
The proper fix for this certainly is in genksyms, but that will take me
some time to get right. In the meantime, we have seen one occurrence of
this in the ehci-hcd code which hits this problem because of the way it
includes C files halfway through the code together with an unlucky mix
of symbol trimming.
In order to workaround this, move the include done in ehci-hub.c early
in ehci-hcd.c, hence making sure the struct definitions are visible to
the entire file. This improves CRC stability of the ehci-hcd exports
even when symbol trimming is enabled.

usblp: fix race between disconnect() and read()

USB: UAS: fix disconnect by unplugging a hub
commit 325b008723b2dd31de020e85ab9d2e9aa4637d35 upstream.
The SCSI layer can go into an ugly loop if you ignore that a device is
gone. You need to report an error in the command rather than in the
return value of the queue method.
We need to specifically check for ENODEV. The issue goes back to the
introduction of the driver.
