When resetting a device the number of active TTs may need to be
corrected by xhci_update_tt_active_eps, but the number of old active
endpoints supplied to it was always zero, so the number of TTs and the
bandwidth reserved for them was not updated, and could rise
unnecessarily.
This affected systems using Intel's Patherpoint chipset, which rely on
software bandwidth checking. For example, a Lenovo X230 would lose the
ability to use ports on the docking station after enough suspend/resume
cycles because the bandwidth calculated would rise with every cycle when
a suitable device is attached.
The correct number of active endpoints is calculated in the same way as
in xhci_reserve_bandwidth.

virt_dev->num_cached_rings counts on freed ring and is not updated
correctly. In xhci_free_or_cache_endpoint_ring() function, the free ring
is added into cache and then num_rings_cache is incremented as below:
virt_dev->ring_cache[rings_cached] =
virt_dev->eps[ep_index].ring;
virt_dev->num_rings_cached++;
here, free ring pointer is added to a current index and then
index is incremented.
So current index always points to empty location in the ring cache.
For getting available free ring, current index should be decremented
first and then corresponding ring buffer value should be taken from ring
cache.
But In function xhci_endpoint_init(), the num_rings_cached index is
accessed before decrement.
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;
virt_dev->num_rings_cached--;
This is bug in manipulating the index of ring cache.
And it should be as below:
virt_dev->num_rings_cached--;
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;

The xHCI in Intel CherryView / Braswell Platform requires
a driver workaround to get xHCI D3 working. Without this
workaround, xHCI might not enter D3.
Workaround is to configure SSIC PORT as "unused" before D3
entry and "used" after D3 exit. This is done through a
vendor specific register (PORT2_SSIC_CONFIG_REG2 at offset
0x883c), in xhci suspend / resume callbacks.
Verified xHCI D3 works fine in CherryView / Braswell platform.

Intel xhci hw that require XHCI_PME_STUCK quirk have as default disabled
xhci from going to D3 state in runtime suspend. Driver needs to verify
it can deal with the hw by calling an ACPI _DSM method to get D3 enabled.

This fixes an issue introduced in commit b23c843992b6 (usb: dwc3:
gadget: fix DEPSTARTCFG for non-EP0 EPs) that made sure we would
only use DEPSTARTCFG once per SetConfig.
The trick is that we should use one DEPSTARTCFG per SetConfig *OR*
SetInterface. SetInterface was completely missed from the original
patch.
This problem became aparent after commit 76e838c9f776 (usb: dwc3:
gadget: return error if command sent to DEPCMD register fails)
added checking of the return status of device endpoint commands.
'Set Endpoint Transfer Resource' command was caught failing
occasionally. This is because the Transfer Resource
Index was not getting reset during a SET_INTERFACE request.
Finally, to fix the issue, was we have to do is make sure that
our start_config_issued flag gets reset whenever we receive a
SetInterface request.
To verify the problem (and its fix), all we have to do is run
test 9 from testusb with 'testusb -t 9 -s 2048 -a -c 5000'.

The ehci_init_driver is used to initialize hcd APIs for each
ehci controller driver, it is designed to be called only one time
and before driver register is called. The current design will
cause ehci_init_driver is called multiple times at probe process,
it will cause hc_driver's initialization affect current running hcd.
We run out NULL pointer dereference problem when one hcd is started
by module_init, and the other is started by otg thread at SMP platform.
The reason for this problem is ehci_init_driver will do memory copy
for current uniform hc_driver, and this memory copy will do memset (as 0)
first, so when the first hcd is running usb_add_hcd, and the second
hcd may clear the uniform hc_driver's space (at ehci_init_driver),
then the first hcd will meet NULL pointer at the same time.
See below two logs:

Phy drivers and the ulpi interface providers depend on the
registration of the ulpi bus. Ulpi registers the bus in
module_init(). This could cause unnecessary bus users'
probe delays. i.e. unnecessary -EPROBE_DEFER happening on
ulpi_drivers in case they're registered before ulpi bus
itself.

Tests with a Sierra Wireless MC7355 have shown that 1199:9041 devices
also require the option_send_setup() code to be used on the USB
interface for the AT port to make unsolicited response codes work
correctly. Move these devices from the qcserial driver to the option
driver like it has been done for the 1199:68c0 devices in commit
d80c0d14183516f184a5ac88e11008ee4c7d2a2e ("USB: qcserial/option: make

Some modules call config_item_init_type_name() and config_group_init_type_name()
with parameter "name" directly controlled by userspace. These two
functions call config_item_set_name() with this name used as a format
string, which can be used to leak information such as content of the
stack to userspace.
For example, make_netconsole_target() in netconsole module calls
config_item_init_type_name() with the name of a newly-created directory.
This means that the following commands give some unexpected output, with
configfs mounted in /sys/kernel/config/ and on a system with a
configured eth0 ethernet interface:
# modprobe netconsole
# mkdir /sys/kernel/config/netconsole/target_%lx
# echo eth0 > /sys/kernel/config/netconsole/target_%lx/dev_name
# echo 1 > /sys/kernel/config/netconsole/target_%lx/enabled
# echo eth0 > /sys/kernel/config/netconsole/target_%lx/dev_name
# dmesg |tail -n1
[ 142.697668] netconsole: target (target_ffffffffc0ae8080) is
enabled, disable to update parameters
The directory name is correct but %lx has been interpreted in the
internal item name, displayed here in the error message used by
store_dev_name() in drivers/net/netconsole.c.
To fix this, update every caller of config_item_set_name to use "%s"
when operating on untrusted input.
This issue was found using -Wformat-security gcc flag, once a __printf
attribute has been added to config_item_set_name().

issues after suspend/resume cycles with AM335x.

current mode is Host and ignore the fact that we have or
not a gadget driver loaded.

Pull SCSI target updates from Nicholas Bellinger:
"It's been a busy development cycle for target-core in a number of
different areas.
The fabric API usage for se_node_acl allocation is now within
target-core code, dropping the external API callers for all fabric
drivers tree-wide.
There is a new conversion to RCU hlists for se_node_acl and
se_portal_group LUN mappings, that turns fast-past LUN lookup into a
completely lockless code-path. It also removes the original
hard-coded limitation of 256 LUNs per fabric endpoint.
The configfs attributes for backends can now be shared between core
and driver code, allowing existing drivers to use common code while
still allowing flexibility for new backend provided attributes.
The highlights include:
- Merge sbc_verify_dif_* into common code (sagi)
- Remove iscsi-target support for obsolete IFMarker/OFMarker
(Christophe Vu-Brugier)
- Add bidi support in target/user backend (ilias + vangelis + agover)
- Move se_node_acl allocation into target-core code (hch)
- Add crc_t10dif_update common helper (akinobu + mkp)
- Handle target-core odd SGL mapping for data transfer memory
(akinobu)
- Move transport ID handling into target-core (hch)
- Move task tag into struct se_cmd + support 64-bit tags (bart)
- Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
paulmck)
- Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch +
paulmck)
- Simplify target backend driver registration (hch)
- Consolidate + simplify target backend attribute implementations
(hch + nab)
- Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch)
- Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab)
- Drop unnecessary core_tpg_register TFO parameter (nab)
- Use 64-bit LUNs tree-wide (hannes)

Add a "param_lock" mutex to each module, and update params.c to use
the correct built-in or module mutex while locking kernel params.
Remove the kparam_block_sysfs_r/w() macros, replace them with direct
calls to kernel_param_[un]lock(module).
The kernel param code currently uses a single mutex to protect
modification of any and all kernel params. While this generally works,
there is one specific problem with it; a module callback function
cannot safely load another module, i.e. with request_module() or even
with indirect calls such as crypto_has_alg(). If the module to be
loaded has any of its params configured (e.g. with a /etc/modprobe.d/*
config file), then the attempt will result in a deadlock between the
first module param callback waiting for modprobe, and modprobe trying to
lock the single kernel param mutex to set the new module's param.
This fixes that by using per-module mutexes, so that each individual module
is protected against concurrent changes in its own kernel params, but is
not blocked by changes to other module params. All built-in modules
continue to use the built-in mutex, since they will always be loaded at
runtime and references (e.g. request_module(), crypto_has_alg()) to them
will never cause load-time param changing.
This also simplifies the interface used by modules to block sysfs access
to their params; while there are currently functions to block and unblock
sysfs param access which are split up by read and write and expect a single
kernel param to be passed, their actual operation is identical and applies
to all params, not just the one passed to them; they simply lock and unlock
the global param mutex. They are replaced with direct calls to
kernel_param_[un]lock(THIS_MODULE), which locks THIS_MODULE's param_lock, or
if the module is built-in, it locks the built-in mutex.

The Octeon OHCI is now supported by the ohci-platform driver, and
USB_OCTEON_OHCI is marked as deprecated. However, it is currently
still necessary to enable it in order to select
USB_OHCI_BIG_ENDIAN_MMIO. Make CPU_CAVIUM_OCTEON select that as well,
so that USB_OCTEON_OHCI is really obsolete.
The old ohci-octeon and ehci-octeon drivers also only enabled big-endian
MMIO in case the CPU was big-endian. Make the selections of
USB_EHCI_BIG_ENDIAN_MMIO and USB_OHCI_BIG_ENDIAN_MMIO conditional, to
match this.

This patch drops unnecessary target_core_fabric_ops parameter usage
for core_tpg_register() during fabric driver TFO->fabric_make_tpg()
se_portal_group creation callback execution.
Instead, use the existing se_wwn->wwn_tf->tf_ops pointer to ensure
fabric driver is really using the same TFO provided at module_init
time.
Also go ahead and drop the forward TFO declarations tree-wide, and
handling the special case for iscsi-target discovery TPG.

'enum extcon' type
This patch just redefine the unique id of supported external connectors without
'enum extcon' type. Because unique id would be used on devictree file(*.dts) to
indicate the specific external connectors like key number of input framework.
So, I have the plan to move this definitions to following header file which
includes the unique id of supported external connectors.
- include/dt-bindings/extcon/extcon.h

The Marvell 28nm HSIC PHY requires the port to be forced to HS mode after
the port power is applied. This is done using the test mode in the PORTSC
register.
As HSIC is always HS, this work-around should be safe to do with all HSIC
PHYs and has been tested on i.MX6S.

Currently, ci_default_pdata is common to all instances of the driver and
gets modified by the core driver code. This is bad if there are multiple
instances of the device with different settings such as the phy type. Fix
this by making a copy of the default platform_data.
