How can this be right? Did you enable the selftest?
Why not? Self tests are passed for this case.
As per the equation given in GCM spec[1], we can see that
if assoclen and cryptlen is 0, then output of GCM is just E(K, Y0)
where Y0 = IV||(0^31)1
I have E(K, Y0) calculated in previous step. And copying it
to destination if assoclen and cryptlen is 0.
Correct me if I am wrong.
It should be E(K, Y0) ^ GHASH(0). So unless GHASH(0) == 0, your
code doesn't work.
OK, GHASH(0) is indeed zero so I guess your code does work after
all.
Sorry. I did not see this message and replied on the other thread.
Thanks and regards,
Lokesh

[PATCH 37/37] usb: gadget: epautoconf: add endpoint capabilities flags verification
Introduce endpoint matching mechanism basing on endpoint capabilities
flags. We check if endpoint supports transfer type and direction requested
in ep descriptor. Since we have this new endpoint matching mechanism
there is no need to have old code guessing endpoint capabilities basing
on its name, so we are getting rid of it.

[PATCH 01/37] usb: gadget: encapsulate endpoint claiming mechanism
So far it was necessary for usb functions to set ep-driver_data in
endpoint obtained from autoconfig to non-null value, to indicate that
endpoint is claimed by function (in autoconfig it was checked if endpoint
has set this field to non-null value, and if it has, it was assumed that
it is claimed). It could cause bugs becouse if some function doesn't
set this field autoconfig could return the same endpoint more than one
time.
To help to avoid such bugs this patch adds claimed flag to struct usb_ep,
and encapsulates endpoint claiming mechanism inside usb_ep_autoconfig_ss()
and usb_ep_autoconfig_reset(), so now usb functions doesn't need to perform
any additional actions to mark endpoint obtained from autoconfig as claimed.

[PATCH 00/37] usb: gadget: rework ep matching and claiming mechanism
Hello, This patch series reworks endpoint matching and claiming mechanism in epautoconf. The patch (1) introduces new safer endpoint claiming method, basing on new 'claimed' flag. It was discussed here [1]. I proposed this solution over year ago and it was accepted, but apparently I forgot to send the final version of patch. Patches (2-3) add the 'capabilities flags' structure and helper macros. This solution is inspired by the 'feature flags' originally proposed by Felipe Balbi in 2013 [2], but unfortunately implementation of this feature has never been completed. Patches (4-36) add' capabilites flags' support to all UDC drivers present in the kernel tree. It's needed to be done before replacing old endpoint matching mechanism, otherwise UDC drivers which doesn't set 'capabilities flags' won't work with new autoconfig. Patch (37) finally replaces old endpoint matching method with the new one basing on capabilities flags. These changes aims to get rid of code, which guesses endpoint capabilities basing on it's name, and introduce new better replacement. In result we have better way to describe types and directions supported by each endpoint. For example the old name-based method didn't allow to have endpoint supporing two types of transfers - there were only ability to support one or all endpoint types. The 'capabilities flags' feature supply precise, flexible and extendible mechanism of description of endpoint hardware limitations, which is desired for proper endpoint matching.

[PATCH v2 1/2] net: can: c_can: Fix default pinmux glitch at init
From: J.D. Schroeder jay.schroe...@garmin.com
The previous change 3973c526ae9c (net: can: c_can: Disable pins when CAN
interface
is down) causes a slight glitch on the pinctrl settings when used. Since
commit ab78029 (drivers/pinctrl: grab default handles from device core),
the device core will automatically set the default pins. This causes
the pins to be momentarily set to the default and then to the sleep
state in register_c_can_dev(). By adding an optional enable state,
boards can set the default pin state to be disabled and avoid the
glitch when the switch from default to sleep first occurs. If the
enable state is not available c_can_pinctrl_select_state() falls
back to using the default pinctrl state.
[Roger Q] - Forward port to v4.2 and use pinctrl_get_select().

How can this be right? Did you enable the selftest?
Why not? Self tests are passed for this case.
As per the equation given in GCM spec[1], we can see that
if assoclen and cryptlen is 0, then output of GCM is just E(K, Y0)
where Y0 = IV||(0^31)1
I have E(K, Y0) calculated in previous step. And copying it
to destination if assoclen and cryptlen is 0.
Correct me if I am wrong.
It should be E(K, Y0) ^ GHASH(0). So unless GHASH(0) == 0, your
code doesn't work.
OK, GHASH(0) is indeed zero so I guess your code does work after
all.
Cheers,

From: J.D. Schroeder jay.schroe...@garmin.com
The previous change 3973c526ae9c (net: can: c_can: Disable pins when
CAN interface
is down) causes a slight glitch on the pinctrl settings when used.
Since
commit ab78029 (drivers/pinctrl: grab default handles from device
core),
the device core will automatically set the default pins. This causes
the pins to be momentarily set to the default and then to the sleep
state in register_c_can_dev(). By adding an optional enable state,
boards can set the default pin state to be disabled and avoid the
glitch when the switch from default to sleep first occurs. If the
enable state is not available c_can_pinctrl_select_state() falls
back to using the default pinctrl state.

Please remove the ifdef, AFAICS there are static inline noop functions
if CONFIG_PINCTRL switched off.
yes, you are right.
On second thoughts
device-pins are not defined if CONFIG_PINCTRL is not set.
so we can't remove the #ifdef.
May be you can use [devm_]pinctrl_get?
Why should we do that? The device core has already done the
pinctrl_get() and it is available in device-pins-p.
True. But It seems, you are going to be only one direct user of pin-p in whole
kernel (outside of pictrl core) !? ;)
pinctrl_get() will just return a pointer on pinctrl associated with dev
if called not the first time and increment kbobj use-counter.
Also, there is nice API pinctrl_get_select() and example in kernel 2c7c2c1d.
So, according to the documentation and pinctrl code, below sequence should work:
struct pinctrl *p;
p = pinctrl_get_select(priv-device, active);
if (!IS_ERR(p))
pinctrl_put(p);
else
pinctrl_pm_select_default_state(priv-device);

[PATCH v3 06/11] usb: gadget.h: Add OTG to gadget interface
The OTG core will use struct otg_gadget_ops to
start/stop the gadget controller.
The main purpose of this interface is to avoid directly
calling usb_gadget_start/stop() from the OTG core as they
wouldn't be defined in the built-in symbol table if
CONFIG_USB_GADGET is m.

[PATCH v3 8/9] usb: dwc3: core: Prevent otg events from disabling themselves
There is a race happening during dwc3_drd_init() that causes
otg events to get disabled. This is what happens.
dwc3_otg_irq() happens immediately when PRTCAP is set to OTG,
even though OEVTEN is 0. This is because BIT 31 IRQ of
OEVT can't be disabled by OEVTEN.
We configure OEVTEN in dwc3_otg_init() but dwc3_otg_irq() has
already saved OEVTEN as 0 into dwc-oevten. So finally when
dwc3_irq_thread_irq() is called we save 0 into OEVTEN
thus disabling OTG irqs forever.
We fix this by disabling IRQs when configuring OEVTEN in
dwc3_otg_init().

[PATCH v3 9/9] usb: dwc3: core: don't break during suspend/resume while we're dual-role
We can't rely just on dr_mode to decide if we're in host or gadget
mode when we're configured as otg/dual-role. So while dr_mode is
OTG, we find out from the otg state machine if we're in host
or gadget mode and take the necessary actions during suspend/resume.
Also make sure that we disable OTG irq and events during system suspend
so that we don't lockup the system during system suspend/resume.

Re: [PATCH] thermal: consistently use int for temperatures
Sascha Hauer writes: The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

How can this be right? Did you enable the selftest?
Why not? Self tests are passed for this case.
As per the equation given in GCM spec[1], we can see that
if assoclen and cryptlen is 0, then output of GCM is just E(K, Y0)
where Y0 = IV||(0^31)1
I have E(K, Y0) calculated in previous step. And copying it
to destination if assoclen and cryptlen is 0.
Correct me if I am wrong.
It should be E(K, Y0) ^ GHASH(0). So unless GHASH(0) == 0, your
code doesn't work.
Yes, thats right. I have considered that.
So, we need GHASH(H, {}, {}).
As per the spec,
GHASH(H, A, C) = X(m + n + 1).
m = n = 0 in our case.
X0 = 0
X1 = (X(m + n) ^ (len(A) || len(C)) . H
X1 = 0 . H (GF(128) Multiplication)
X1 = 0
The same thing is given in the Test case 1 of the spec. GHASH(H, {}, {}) = 0
Thanks and regards,
Lokesh

[PATCH v3 10/11] usb: otg: Add dual-role device (DRD) support
DRD mode is a reduced functionality OTG mode. In this mode
we don't support SRP, HNP and dynamic role-swap.
In DRD operation, the controller mode (Host or Peripheral)
is decided based on the ID pin status. Once a cable plug (Type-A
or Type-B) is attached the controller selects the state
and doesn't change till the cable in unplugged and a different
cable type is inserted.
As we don't need most of the complex OTG states and OTG timers
we implement a lean DRD state machine in usb-otg.c.
The DRD state machine is only interested in 2 hardware inputs
'id' and 'vbus; that are still passed via the origintal struct otg_fsm.
Most of the usb-otg.c functionality remains the same except
adding a new parameter to usb_otg_register() to indicate that
the OTG controller needs to operate in DRD mode.

[PATCH v3 07/11] usb: otg: add OTG core
The OTG core instantiates the OTG Finite State Machine
per OTG controller and manages starting/stopping the
host and gadget controllers based on the bus state.
It provides APIs for the following tasks
- Registering an OTG capable controller
- Registering Host and Gadget controllers to OTG core
- Providing inputs to and kicking the OTG state machine

[PATCH v3 11/11] usb: otg: hub: Notify OTG fsm when A device sets b_hnp_enable
This is the a_set_b_hnp_enable flag in the OTG state machine
diagram and must be set when the A-Host has successfully set
the b_hnp_enable feature of the OTG-B-Peripheral attached to it.
When this bit changes we kick our OTG FSM to make note of the
change and act accordingly.

[PATCH v3 09/11] usb: gadget: udc: adapt to OTG core
The OTG state machine needs a mechanism to start and
stop the gadget controller. Add usb_gadget_start()
and usb_gadget_stop().
Register with OTG core when gadget function driver
is available and unregister when function driver is unbound.
We need to unlock the usb_lock mutexbefore calling
usb_otg_register_gadget() in udc_bind_to_driver() and
usb_gadget_remove_driver() else it will cause a circular
locking dependency.
Ignore softconnect sysfs control when we're in OTG
mode as OTG FSM takes care of gadget softconnect using
the b_bus_req mechanism.

The existing usb_add/remove_hcd() functionality
remains unchanged for non-OTG devices. For OTG
devices they only register the HCD with the OTG core.
Introduce usb_otg_add/remove_hcd() for use by OTG core.
These functions actually add/remove the HCD.

commit ab78029 (drivers/pinctrl: grab default handles from device
core),
the device core will automatically set the default pins. This causes
the pins to be momentarily set to the default and then to the sleep
state in register_c_can_dev(). By adding an optional enable state,
boards can set the default pin state to be disabled and avoid the
glitch when the switch from default to sleep first occurs. If the
enable state is not available c_can_pinctrl_select_state() falls
back to using the default pinctrl state.

yes, you are right.
On second thoughts
device-pins are not defined if CONFIG_PINCTRL is not set.
so we can't remove the #ifdef.
May be you can use [devm_]pinctrl_get?
Why should we do that? The device core has already done the
pinctrl_get() and it is available in device-pins-p.
True. But It seems, you are going to be only one direct user of pin-p in
whole
kernel (outside of pictrl core) !? ;)
good point :).
pinctrl_get() will just return a pointer on pinctrl associated with dev
if called not the first time and increment kbobj use-counter.
Also, there is nice API pinctrl_get_select() and example in kernel 2c7c2c1d.
So, according to the documentation and pinctrl code, below sequence should
work:
struct pinctrl *p;
p = pinctrl_get_select(priv-device, active);
if (!IS_ERR(p))
pinctrl_put(p);
else
pinctrl_pm_select_default_state(priv-device);
This is much neater. I will give that a try. Thanks.

[PATCH v3 00/11] USB: OTG/DRD Core functionality
Hi, This series centralizes OTG/Dual-role functionality in the kernel. As of now I've got Dual-role functionality working pretty reliably on dra7-evm and am437x-gp-evm. xhci side of things for OTG/DRD use are already in v4.2 http://thread.gmane.org/gmane.linux.kernel/1923161 DWC3 controller and platform related patches are sent separately. Changelog: - v3: - all otg related definations now in otg.h - single kernel config USB_OTG to enable OTG core and FSM. - resolved symbol dependency issues. - use dev_vdbg instead of VDBG() in usb-otg-fsm.c - rebased on v4.2-rc1 v2: - Use add/remove_hcd() instead of start/stop_hcd() to enable/disable the host controller - added dual-role-device (DRD) state machine which is a much simpler mode of operation when compared to OTG. Here we don't support fancy OTG features like HNP, SRP, on the fly role-swap. The mode of operation is determined based on ID pin (cable type) and the role doesn't change till the cable type changes. Why?: Most of the OTG drivers have been dealing with the OTG state machine themselves and there is a scope for code re-use. This has been partly addressed by the usb/common/usb-otg-fsm.c but it still leaves the instantiation of the state machine and OTG timers to the controller drivers. We re-use usb-otg-fsm.c but go one step further by instantiating the state machine and timers thus making it easier for drivers to implement OTG functionality. Newer OTG cores support standard host interface (e.g. xHCI?) so host and gadget functionality are no longer closely knit like older cores. There needs to be a way to co-ordinate the operation of the host and gadget in OTG mode. i.e. to stop and start them from a central location. This central location should be the USB OTG core. Host and gadget controllers might be sharing resources and can't be always running. One has to be stopped for the other to run. This can't be done as of now and can be done from the OTG core. What?: - The OTG core instantiates the OTG/DRD Finite State Machine per OTG controller and manages starting/stopping the host and gadget controllers based on the bus state. It provides APIs for the following - Registering an OTG capable controller struct otg_fsm *usb_otg_register(struct device *parent_dev, struct otg_fsm_ops *fsm_ops, bool drd_only); int usb_otg_unregister(struct device *parent_dev); - Registering Host controllers to OTG core (used by hcd-core) int usb_otg_register_hcd(struct usb_hcd *hcd, unsigned int irqnum, unsigned long irqflags, struct otg_hcd_ops *ops); int usb_otg_unregister_hcd(struct usb_hcd *hcd); - Registering Gadget controllers to OTG core (used by udc-core) int usb_otg_register_gadget(struct usb_gadget *gadget, struct otg_gadget_ops *ops); int usb_otg_unregister_gadget(struct usb_gadget *gadget); - Providing inputs to and kicking the OTG state machine void usb_otg_sync_inputs(struct otg_fsm *fsm); int usb_otg_kick_fsm(struct device *hcd_gcd_device); - Getting controller device structure from OTG state machine instance struct device *usb_otg_fsm_to_dev(struct otg_fsm *fsm); 'struct otg_fsm' is the interface to the OTG state machine. It contains inputs to the fsm, status of the fsm and operations for the OTG controller driver. Usage model: --- - The OTG controller device is assumed to be the parent of the host and gadget controller. It must call usb_otg_register() before populating the host and gadget devices so that the OTG core is aware that it is an OTG device before the host gadget register. The OTG controller must provide struct otg_fsm_ops * which will be called by the OTG core depending on OTG bus state. - The host/gadget core stacks are modified to inform the OTG core whenever a new host/gadget device is added. The OTG core then checks if the host/gadget is part of the OTG controller and if yes then prevents the host/gadget from starting till both host and gadget are registered, OTG state machine is running and the USB bus state is appropriate to start host/gadget. For this APIs have been added to host/gadget stacks to start/stop the controllers from the OTG core. - No modification is needed for the host/gadget controller drivers. They must ensure that their start/stop methods can be called repeatedly and any shared resources between host gadget are properly managed. The OTG core ensures that both are not started simultaneously. - The OTG core instantiates one OTG state machine per OTG controller and the necessary OTG timers to manage OTG state timeouts. If drd_only parameter is set during usb_otg_register() then it instanciates a DRD (dual-role device) state machine instead. The state machine is started when both host gadget register and stopped when either of them unregisters. The controllers are started and stopped depending on bus state. - During the lifetime of the OTG state

Re: [PATCH RESEND 1/7] tty: serial: 8250: omap: fix kernel crash in suspend-to-ram
Hi Sekhar,

omap_device infrastructure has a suspend_noirq hook which
runtime suspends all devices late in the suspend cycle (see
_od_suspend_noirq() in arch/arm/mach-omap2/omap_device.c)
Why is omap2 the only arch/SoC that does this; ie., call the runtime
callbacks after the system pm callbacks?
Whatever positive it brings, it's a mess at the driver level.
For example, this driver has to hook prepare()/complete() so it can
set local state so that it can detect when the runtime suspend
is being called during system suspend.
Regards,
Peter Hurley
This leads to a NULL pointer exception in 8250_omap driver
since by the time omap8250_runtime_suspend() is called, 8250_dma
driver has already set rxchan to NULL via serial8250_release_dma().
Make an explicit check to see if rxchan is NULL in
runtime_{suspend|resume} hooks to fix this.

[PATCH 00/10] i2c/drm: fix i2c adapter device driver user counter
The 01/10 change adds and exports new of_get_i2c_adapter_by_node() interface of i2c core, the rest of patches fix current users of of_find_i2c_adapter_by_node() interface. of_find_i2c_adapter_by_node() call requires quite often missing put_device(), and i2c_put_adapter() releases a device locked by i2c_get_adapter() only. In general module_put(adapter-owner) and put_device(dev) are not interchangeable.

[PATCH] i2c: core: only use set_scl for bus recovery after calling prepare_recovery
Using set_scl may be ineffective before calling the driver specific

instead of setting SCL in i2c_generic_scl_recovery, move it to
i2c_generic_recovery (after the optional prepare_recovery).

[PATCH] i2c: omap: fix bus recovery setup
At least on the AM335x, enabling OMAP_I2C_SYSTEST_ST_EN is not enough to allow direct access to the SCL and SDA pins. In addition to ST_EN, we need to set the TMODE to 0b11 (Loop back SDA/SCL IO mode select). Also, as the reset values of SCL_O and SDA_O are 0 (which means drive low level), we need to set them to 1 (which means high-impedance) to avoid unwanted changes on the pins. As a precaution, reset all these bits to their default values after recovery is complete.

How can this be right? Did you enable the selftest?
Why not? Self tests are passed for this case.
As per the equation given in GCM spec[1], we can see that
if assoclen and cryptlen is 0, then output of GCM is just E(K, Y0)
where Y0 = IV||(0^31)1
I have E(K, Y0) calculated in previous step. And copying it
to destination if assoclen and cryptlen is 0.
Correct me if I am wrong.
It should be E(K, Y0) ^ GHASH(0). So unless GHASH(0) == 0, your
code doesn't work.

Since
commit ab78029 (drivers/pinctrl: grab default handles from device

the device core will automatically set the default pins. This causes
the pins to be momentarily set to the default and then to the sleep
state in register_c_can_dev(). By adding an optional enable state,
boards can set the default pin state to be disabled and avoid the
glitch when the switch from default to sleep first occurs. If the
enable state is not available c_can_pinctrl_select_state() falls
back to using the default pinctrl state.

Change -determine_rate() prototype to return 0 or an error code, and pass
a pointer to a clk_rate_request structure containing the expected target

The clk_rate_request structure might be extended in the future to contain
other kind of constraints like the rounding policy, the maximum clock
inaccuracy or other things that are not yet supported by the CCF

Shouldn't this return an error now? And then assigning req-rate
wouldn't be necessary. Sorry I must have missed this last round.
Actually I wanted to keep the existing behavior: return a 0 rate (not
an error) when there is no mux or rate ops.
That's something we can change afterwards, but it might reveals
new bugs if some users are checking for a 0 rate to detect errors.

Shouldn't this return an error now? And then assigning req-rate
wouldn't be necessary. Sorry I must have missed this last round.
Actually I wanted to keep the existing behavior: return a 0 rate (not
an error) when there is no mux or rate ops.
That's something we can change afterwards, but it might reveals
new bugs if some users are checking for a 0 rate to detect errors.
Ok. Care to send the patch now to do that while we're thinking about it?
We can test it out for a month or two.

Ugh, you cannot allocate crypto transforms in the data path. You
should allocate it in init instead. Also using ctr(aes) is overkill.
Just use aes and do the xor by hand.
Ill take care of this.

The ctx is shared memory and you must not write to it as multiple

The IV is only 12 bytes long so you're corrupting memory here.
You should use rctx here too.

How can this be right? Did you enable the selftest?
Why not? Self tests are passed for this case.
As per the equation given in GCM spec[1], we can see that
if assoclen and cryptlen is 0, then output of GCM is just E(K, Y0)
where Y0 = IV||(0^31)1
I have E(K, Y0) calculated in previous step. And copying it
to destination if assoclen and cryptlen is 0.
Correct me if I am wrong.
Thanks and regards,
Lokesh
