commit 7bab01ecc6c43da882333c6db39741cb43677004 upstream.
The device exposes AT, NMEA and DIAG ports in both USB configurations.
The patch explicitly ignores interfaces 0 and 1, as they're bound to
other drivers already; and also interface 6, which is a GNSS interface
for which we don't have a driver yet.

[ Upstream commit 5d111f5190848d6fb1c414dc57797efea3526a2f ]
wait_for_connected() wait till a port change status to
USB_PORT_STAT_CONNECTION, but this is not possible if
the port is unpowered. The loop will only exit at timeout.
Such case take place if an over-current incident happen
while system is in S3. Then during resume wait_for_connected()
will wait 2s, which may be noticeable by the user.

commit 4d644abf25698362bd33d17c9ddc8f7122c30f17 upstream.
Commit 1b9ba000 ("Allow function drivers to pause control
transfers") states that USB_GADGET_DELAYED_STATUS is only
supported if data phase is 0 bytes.
It seems that when the length is not 0 bytes, there is no
need to explicitly delay the data stage since the transfer
is not completed until the user responds. However, when the
length is 0, there is no data stage and the transfer is
finished once setup() returns, hence there is a need to
explicitly delay completion.
This manifests as the following bugs:
Prior to 946ef68ad4e4 ('Let setup() return
USB_GADGET_DELAYED_STATUS'), when setup is 0 bytes, ffs
would require user to queue a 0 byte request in order to
clear setup state. However, that 0 byte request was actually
not needed and would hang and cause errors in other setup
requests.
After the above commit, 0 byte setups work since the gadget
now accepts empty queues to ep0 to clear the delay, but all
other setups hang.

commit 50b9773c13bffbef32060e67c4483ea7b2eca7b5 upstream.
The current code is broken as it re-defines "req" inside the
if block, then goto out of it. Thus the request that ends
up being sent is not the one that was populated by the
code in question.
This fixes RNDIS driver autodetect by Windows 10 for me.
The bug was introduced by Chris rework to remove the local
queuing inside the if { } block of the redefined request.

commit 56406e017a883b54b339207b230f85599f4d70ae upstream.
The commit 3bc04e28a030 ("usb: dwc2: host: Get aligned DMA in a more
supported way") introduced a common way to align DMA allocations.
The code in the commit aligns the struct dma_aligned_buffer but the
actual DMA address pointed by data[0] gets aligned to an offset from
the allocated boundary by the kmalloc_ptr and the old_xfer_buffer
pointers.
This is against the recommendation in Documentation/DMA-API.txt which
states:
Therefore, it is recommended that driver writers who don't take
special care to determine the cache line size at run time only map
virtual regions that begin and end on page boundaries (which are
guaranteed also to be cache line boundaries).
The effect of this is that architectures with non-coherent DMA caches
may run into memory corruption or kernel crashes with Unhandled
kernel unaligned accesses exceptions.
Fix the alignment by positioning the DMA area in front of the allocation
and use memory at the end of the area for storing the orginal
transfer_buffer pointer. This may have the added benefit of increased
performance as the DMA area is now fully aligned on all architectures.
Tested with Lantiq xRX200 (MIPS) and RPi Model B Rev 2 (ARM).

commit 249a32b7eeb3edb6897dd38f89651a62163ac4ed upstream.
Based on USB2.0 Spec Section 11.12.5,
"If a hub has per-port power switching and per-port current limiting,
an over-current on one port may still cause the power on another port
to fall below specific minimums. In this case, the affected port is
placed in the Power-Off state and C_PORT_OVER_CURRENT is set for the
port, but PORT_OVER_CURRENT is not set."
so let's check C_PORT_OVER_CURRENT too for over current condition.

commit 229bc19fd7aca4f37964af06e3583c1c8f36b5d6 upstream.
Don't rely on event interrupt (EINT) bit alone to detect pending port
change in resume. If no change event is detected the host may be suspended
again, oterwise roothubs are resumed.
There is a lag in xHC setting EINT. If we don't notice the pending change
in resume, and the controller is runtime suspeded again, it causes the
event handler to assume host is dead as it will fail to read xHC registers
once PCI puts the controller to D3 state.

The EINT lag is described in a additional note in xhci specs 4.19.2:
"Due to internal xHC scheduling and system delays, there will be a lag
between a change bit being set and the Port Status Change Event that it
generated being written to the Event Ring. If SW reads the PORTSC and
sees a change bit set, there is no guarantee that the corresponding Port
Status Change Event has already been written into the Event Ring."

commit f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 upstream.
In general, accessing userspace memory beyond the length of the supplied
buffer in VFS read/write handlers can lead to both kernel memory corruption
(via kernel_read()/kernel_write(), which can e.g. be triggered via
sys_splice()) and privilege escalation inside userspace.
Fix it by using simple_read_from_buffer() instead of custom logic.

commit d850c1658328e757635a46763783c6fd56390dcb upstream.
commit 44a182b9d177 ("xhci: Fix use-after-free in xhci_free_virt_device")
set dev->udev pointer to NULL in xhci_free_dev(), it will cause kernel
panic in trace_xhci_free_virt_device. This patch reimplement the trace
function trace_xhci_free_virt_device, remove dev->udev dereference and
added more useful parameters to show in the trace function,it also makes
sure dev->udev is not NULL before calling trace_xhci_free_virt_device.
This issue happened when xhci-hcd trace is enabled and USB devices hot
plug test. Original use-after-free patch went to stable so this needs so
be applied there as well.

commit 68816e16b4789f2d05e77b6dcb77564cf5d6a8d8 upstream.
According to UCSI Specification, Connector Change Event only
means a change in the Connector Status and Operation Mode
fields of the STATUS data structure. So any other change
should create another event.
Unfortunately on some platforms the firmware acting as PPM
(platform policy manager - usually embedded controller
firmware) still does not report any other status changes if
there is a connector change event. So if the connector power
or data role was changed when a device was plugged to the
connector, the driver does not get any indication about
that. The port will show wrong roles if that happens.
To fix the issue, always checking the data and power role
together with a connector change event.

commit 1f9f9d168ce619608572b01771c47a41b15429e6 upstream.
This fixes an issue where the driver fails with an error:
ioremap error for 0x3f799000-0x3f79a000, requested 0x2, got 0x0
On some platforms the UCSI ACPI mailbox SystemMemory
Operation Region may be setup before the driver has been
loaded. That will lead into the driver failing to map the
mailbox region, as it has been already marked as write-back
memory. acpi_os_ioremap() for x86 uses ioremap_cache()
unconditionally.
When the issue happens, the embedded controller has a
pending query event for the UCSI notification right after
boot-up which causes the operation region to be setup before
UCSI driver has been loaded.
The fix is to notify acpi core that the driver is about to
access memory region which potentially overlaps with an
operation region right before mapping it.
acpi_release_memory() will check if the memory has already
been setup (mapped) by acpi core, and deactivate it (unmap)
if it has. The driver is then able to map the memory with
ioremap_nocache() and set the memtype to uncached for the
region.

commit 8760675932ddb614e83702117d36ea644050c609 upstream.
The dwc2_get_ls_map() use ttport to reference into the
bitmap if we're on a multi_tt hub. But the bitmaps index
from 0 to (hub->maxchild - 1), while the ttport index from
1 to hub->maxchild. This will cause invalid memory access
when the number of ttport is hub->maxchild.
Without this patch, I can easily meet a Kernel panic issue
if connect a low-speed USB mouse with the max port of FE2.1
multi-tt hub (1a40:0201) on rk3288 platform.

commit 2f839823382748664b643daa73f41ee0cc01ced6 upstream.
Silicon Labs defines alternative VID/PID pairs for some chips that when
used will automatically install drivers for Windows users without manual
intervention. Unfortunately, these IDs are not recognized by the Linux
module, so using these IDs improves user experience on one platform but
degrades it on Linux. This patch addresses this problem.

A couple of bugs in the driver are preventing SETUP packets
with an OUT data phase from working properly.
Interestingly those are incredibly rare (RNDIS typically
uses them and thus is broken without this fix).
The main problem was an incorrect register offset being
applied for arming RX on EP0. The other problem relates
to stalling such a packet before the data phase, in which
case we don't get an ACK cycle, and get the next SETUP
packet directly, so we shouldn't reject it.

The Aspeed BMC SoCs support a "virtual hub" function. It provides some
HW support for a top-level USB2 hub behind which sit 5 gadget "ports".
This driver adds support for the full functionality, emulating the
hub standard requests and exposing 5 UDC gadget drivers corresponding
to the ports.
The hub itself has HW provided dedicated EP0 and EP1 (the latter for
hub interrupts). It also has dedicated EP0s for each function. For
other endpoints, there's a pool of 15 "generic" endpoints that are
shared among the ports.
The driver relies on my previous patch adding a "dispose" EP op to
handle EP allocation between ports. EPs are allocated from the shared
pool in the UDC "match_ep" callback and assigned to the UDC instance
(added to the gadget ep_list).
When the composite driver gets unbound, the new hook will allow the UDC
to clean things up and return those EPs to the shared pool.

Some low-speed and full-speed devices (for example, bluetooth)
do not have time to initialize. For them, ETIMEDOUT is a valid error.
We need to give them another try. Otherwise, they will
never be initialized correctly and in dmesg will be messages
"Bluetooth: hci0 command 0x1002 tx timeout" or similars.

commit 4a014a7339f441b0851ce012f469c0fadac61c81 upstream.
When printer_write() calls usb_ep_queue(), a udc driver (e.g.
renesas_usbhs driver) may call usb_gadget_giveback_request() in
the udc .queue ops immediately. Then, printer_write() calls
list_add(&req->list, &dev->tx_reqs_active) wrongly. After that,
if we do unbind the printer driver, WARN_ON() happens in
printer_func_unbind() because the list entry is not removed.
So, this patch moves list_add(&req->list, &dev->tx_reqs_active)
calling before usb_ep_queue().

The USB Type-C PHY in Intel WhiskeyCove PMIC has build-in
USB Type-C state machine which we were relying on to

dependency and configures the CC line according to commands

This fixes an issue where USB devices attached to the USB
Type-C port do not get enumerated. When acting as
source/host, the HW FSM sometimes fails to configure the PHY
correctly.

The proposed patch adds compatibility quirks. Because the drive requires two
quirks (one to work with UAS, and another to work with usb-storage), adding this
under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS
receive the quirk. With the patch, the drive works reliably on UAS and usb-
storage.

commit a0d6ec88090d7b1b008429c44532a388e29bb1bd upstream.
pdev_nr and rhport can be controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/usb/usbip/vhci_sysfs.c:238 detach_store() warn: potential spectre issue 'vhcis'
drivers/usb/usbip/vhci_sysfs.c:328 attach_store() warn: potential spectre issue 'vhcis'
drivers/usb/usbip/vhci_sysfs.c:338 attach_store() warn: potential spectre issue 'vhci->vhci_hcd_ss->vdev'
drivers/usb/usbip/vhci_sysfs.c:340 attach_store() warn: potential spectre issue 'vhci->vhci_hcd_hs->vdev'
Fix this by sanitizing pdev_nr and rhport before using them to index
vhcis and vhci->vhci_hcd_ss->vdev respectively.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

stub_probe() calls put_busid_priv() in an error path when device isn't
found in the busid_table. Fix it by making put_busid_priv() safe to be
called with null struct bus_id_priv pointer.
This problem happens when "usbip bind" is run without loading usbip_host
driver and then running modprobe. The first failed bind attempt unbinds
the device from the original driver and when usbip_host is modprobed,
stub_probe() runs and doesn't find the device in its busid table and calls
put_busid_priv(0 with null bus_id_priv pointer.

usbip_host updates device status without holding lock from stub probe,
disconnect and rebind code paths. When multiple requests to import a
device are received, these unprotected code paths step all over each
other and drive fails with NULL-ptr deref and use-after-free errors.
The driver uses a table lock to protect the busid array for adding and
deleting busids to the table. However, the probe, disconnect and rebind
paths get the busid table entry and update the status without holding
the busid table lock. Add a new finer grain lock to protect the busid
entry. This new lock will be held to search and update the busid entry
fields from get_busid_idx(), add_match_busid() and del_match_busid().
match_busid_show() does the same to access the busid entry fields.
get_busid_priv() changed to return the pointer to the busid entry holding
the busid lock. stub_probe(), stub_disconnect() and stub_device_rebind()
call put_busid_priv() to release the busid lock before returning. This
changes fixes the unprotected code paths eliminating the race conditions
in updating the busid entries.
