| * KEYS: add SP800-56A KDF support for DHStephan Mueller2017-04-041-8/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SP800-56A defines the use of DH with key derivation function based on a counter. The input to the KDF is defined as (DH shared secret || other information). The value for the "other information" is to be provided by the caller. The KDF is implemented using the hash support from the kernel crypto API. The implementation uses the symmetric hash support as the input to the hash operation is usually very small. The caller is allowed to specify the hash name that he wants to use to derive the key material allowing the use of all supported hashes provided with the kernel crypto API. As the KDF implements the proper truncation of the DH shared secret to the requested size, this patch fills the caller buffer up to its size. The patch is tested with a new test added to the keyutils user space code which uses a CAVS test vector testing the compliance with SP800-56A.

| * KEYS: Keyring asymmetric key restrict method with chainingMat Martineau2017-04-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a restrict_link_by_key_or_keyring_chain link restriction that searches for signing keys in the destination keyring in addition to the signing key or keyring designated when the destination keyring was created. Userspace enables this behavior by including the "chain" option in the keyring restriction: keyctl(KEYCTL_RESTRICT_KEYRING, keyring, "asymmetric", "key_or_keyring:<signing key>:chain"); Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>

| * KEYS: Add KEYCTL_RESTRICT_KEYRINGMat Martineau2017-04-041-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keyrings recently gained restrict_link capabilities that allow individual keys to be validated prior to linking. This functionality was only available using internal kernel APIs. With the KEYCTL_RESTRICT_KEYRING command existing keyrings can be configured to check the content of keys before they are linked, and then allow or disallow linkage of that key to the keyring. To restrict a keyring, call: keyctl(KEYCTL_RESTRICT_KEYRING, key_serial_t keyring, const char *type, const char *restriction) where 'type' is the name of a registered key type and 'restriction' is a string describing how key linkage is to be restricted. The restriction option syntax is specific to each key type. Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
| * KEYS: Add an optional lookup_restriction hook to key_typeMat Martineau2017-04-041-0/+9
| | | | | | | | | | | | | | | | | | | | The restrict_link functions used to validate keys as they are linked to a keyring can be associated with specific key types. Each key type may be loaded (or not) at runtime, so lookup of restrict_link functions needs to be part of the key type implementation to ensure that the requested keys can be examined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace struct key's restrict_link function pointer with a pointer to the new struct key_restriction. The structure contains pointers to the restriction function as well as relevant data for evaluating the restriction. The garbage collector checks restrict_link->keytype when key types are unregistered. Restrictions involving a removed key type are converted to use restrict_link_reject so that restrictions cannot be removed by unregistering key types.

| * KEYS: Split role of the keyring pointer for keyring restrict functionsMat Martineau2017-04-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The first argument to the restrict_link_func_t functions was a keyring pointer. These functions are called by the key subsystem with this argument set to the destination keyring, but restrict_link_by_signature expects a pointer to the relevant trusted keyring. Restrict functions may need something other than a single struct key pointer to allow or reject key linkage, so the data used to make that decision (such as the trust keyring) is moved to a new, fourth argument. The first argument is now always the destination keyring. Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
| * KEYS: Use a typedef for restrict_link function pointersMat Martineau2017-04-031-4/+1

This extends the nature of the types of patches that can be applied by live patching infrastructure. The code stems from the design proposal made [1] back in November 2014. It's a hybrid of SUSE's kGraft and RH's kpatch, combining advantages of both: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible.

| * | | livepatch: allow removal of a disabled patchJosh Poimboeuf2017-03-081-19/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we do not allow patch module to unload since there is no method to determine if a task is still running in the patched code. The consistency model gives us the way because when the unpatching finishes we know that all tasks were marked as safe to call an original function. Thus every new call to the function calls the original code and at the same time no task can be somewhere in the patched code, because it had to leave that code to be marked as safe. We can safely let the patch module go after that. Completion is used for synchronization between module removal and sysfs infrastructure in a similar way to commit 942e443127e9 ("module: Fix mod->mkobj.kobj potentially freed too early"). Note that we still do not allow the removal for immediate model, that is no consistency model. The module refcount may increase in this case if somebody disables and enables the patch several times. This should not cause any harm. With this change a call to try_module_get() is moved to __klp_enable_patch from klp_register_patch to make module reference counting symmetric (module_put() is in a patch disable path) and to allow to take a new reference to a disabled module when being enabled. Finally, we need to be very careful about possible races between klp_unregister_patch(), kobject_put() functions and operations on the related sysfs files. kobject_put(&patch->kobj) must be called without klp_mutex. Otherwise, it might be blocked by enabled_store() that needs the mutex as well. In addition, enabled_store() must check if the patch was not unregisted in the meantime. There is no need to do the same for other kobject_put() callsites at the moment. Their sysfs operations neither take the lock nor they access any data that might be freed in the meantime. There was an attempt to use kobjects the right way and prevent these races by design. But it made the patch definition more complicated and opened another can of worms.

This is the foundation which will eventually enable us to patch those ~10% of security patches which change function or data semantics. This is the biggest remaining piece needed to make livepatch more generally useful. This code stems from the design proposal made by Vojtech [1] in November 2014. It's a hybrid of kGraft and kpatch: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible. Patches are applied on a per-task basis, when the task is deemed safe to switch over. When a patch is enabled, livepatch enters into a transition state where tasks are converging to the patched state. Usually this transition state can complete in a few seconds. The same sequence occurs when a patch is disabled, except the tasks converge from the patched state to the unpatched state. An interrupt handler inherits the patched state of the task it interrupts. The same is true for forked tasks: the child inherits the patched state of the parent. Livepatch uses several complementary approaches to determine when it's safe to patch tasks: 1. The first and most effective approach is stack checking of sleeping tasks. If no affected functions are on the stack of a given task, the task is patched. In most cases this will patch most or all of the tasks on the first try. Otherwise it'll keep trying periodically. This option is only available if the architecture has reliable stacks (HAVE_RELIABLE_STACKTRACE). 2. The second approach, if needed, is kernel exit switching. A task is switched when it returns to user space from a system call, a user space IRQ, or a signal. It's useful in the following cases: a) Patching I/O-bound user tasks which are sleeping on an affected function. In this case you have to send SIGSTOP and SIGCONT to force it to exit the kernel and be patched. b) Patching CPU-bound user tasks. If the task is highly CPU-bound then it will get patched the next time it gets interrupted by an IRQ. c) In the future it could be useful for applying patches for architectures which don't yet have HAVE_RELIABLE_STACKTRACE. In this case you would have to signal most of the tasks on the system. However this isn't supported yet because there's currently no way to patch kthreads without HAVE_RELIABLE_STACKTRACE. 3. For idle "swapper" tasks, since they don't ever exit the kernel, they instead have a klp_update_patch_state() call in the idle loop which allows them to be patched before the CPU enters the idle state. (Note there's not yet such an approach for kthreads.) All the above approaches may be skipped by setting the 'immediate' flag in the 'klp_patch' struct, which will disable per-task consistency and patch all tasks immediately. This can be useful if the patch doesn't change any function or data semantics. Note that, even with this flag set, it's possible that some tasks may still be running with an old version of the function, until that function returns. There's also an 'immediate' flag in the 'klp_func' struct which allows you to specify that certain functions in the patch can be applied without per-task consistency. This might be useful if you want to patch a common function like schedule(), and the function change doesn't need consistency but the rest of the patch does. For architectures which don't have HAVE_RELIABLE_STACKTRACE, the user must set patch->immediate which causes all tasks to be patched immediately. This option should be used with care, only when the patch doesn't change any function or data semantics. In the future, architectures which don't have HAVE_RELIABLE_STACKTRACE may be allowed to use per-task consistency if we can come up with another way to patch kthreads. The /sys/kernel/livepatch/<patch>/transition file shows whether a patch is in transition. Only a single patch (the topmost patch on the stack) can be in transition at a given time. A patch can remain in transition indefinitely, if any of the tasks are stuck in the initial patch state. A transition can be reversed and effectively canceled by writing the opposite value to the /sys/kernel/livepatch/<patch>/enabled file while the transition is in progress. Then all the tasks will attempt to converge back to the original patch state.

For a part the mapping by hid-core is accomplished by a fixup in hid-sony as the motion axes actually use vendor specific usage pages. This patch makes the DS4 use a separate input device for the motion sensors and reports acceleration data through ABS_X-ABS_Z and gyroscope data through ABS_RX-ABS_RZ. In addition it extends the event spec to allow gyroscope data through ABS_RX-ABS_RZ when INPUT_PROP_ACCELEROMETER is set. This change was suggested by Peter Hutterer during a discussion on linux-input.

The extra week before the merge window actually resulted in some of the type of fixes that usually arrive after the merge window already starting to trickle in from eager developers using -next, I'm impressed. I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal with the onset of Samsung patches. It works great. Apart from that it is a boring round, just incremental updates and fixes all over the place, no serious core changes or anything exciting like that. The most pleasing to see is Julia Cartwrights work to audit the irqchip-providing drivers for realtime locking compliance. It's one of those "I should really get around to looking into that" things that have been on my TODO list since forever. Summary: Core changes: - add bi-directional and output-enable pin configurations to the generic bindings and generic pin controlling core. New drivers or subdrivers: - Armada 37xx SoC pin controller and GPIO support. - Axis ARTPEC-6 SoC pin controller support. - AllWinner A64 R_PIO controller support, and opening up the AllWinner sunxi driver for ARM64 use. - Rockchip RK3328 support. - Renesas R-Car H3 ES2.0 support. - STM32F469 support in the STM32 driver. - Aspeed G4 and G5 pin controller support. Improvements: - a whole slew of realtime improvements to drivers implementing irqchips: BCM, AMD, SiRF, sunxi, rockchip. - switch meson driver to get the GPIO ranges from the device tree. - input schmitt trigger support on the Rockchip driver. - enable the sunxi (AllWinner) driver to also be used on ARM64 silicon. - name the Qualcomm QDF2xxx GPIO lines. - support GMMR GPIO regions on the Intel Cherryview. This fixes a serialization problem on these platforms. - pad retention support for the Samsung Exynos 5433. - handle suspend-to-ram in the AT91-pio4 driver. - pin configuration support in the Aspeed driver. Cleanups: - the final name of Rockchip RK1108 was RV1108 so rename the driver and variables to stay consistent" * tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (80 commits) pinctrl: mediatek: Add missing pinctrl bindings for mt7623 pinctrl: artpec6: Fix return value check in artpec6_pmx_probe() pinctrl: artpec6: Remove .owner field for driver pinctrl: tegra: xusb: Silence sparse warnings ARM: at91/at91-pinctrl documentation: fix spelling mistake: "contoller" -> "controller" pinctrl: make artpec6 explicitly non-modular pinctrl: aspeed: g5: Add pinconf support pinctrl: aspeed: g4: Add pinconf support pinctrl: aspeed: Add core pinconf support pinctrl: aspeed: Document pinconf in devicetree bindings pinctrl: Add st,stm32f469-pinctrl compatible to stm32-pinctrl pinctrl: stm32: Add STM32F469 MCU support Documentation: dt: Remove ngpios from stm32-pinctrl binding pinctrl: stm32: replace device_initcall() with arch_initcall() pinctrl: stm32: add possibility to use gpio-ranges to declare bank range pinctrl: armada-37xx: Add gpio support pinctrl: armada-37xx: Add pin controller support for Armada 37xx pinctrl: dt-bindings: Add documentation for Armada 37xx pin controllers pinctrl: core: Make pinctrl_init_controller() static pinctrl: generic: Add bi-directional and output-enable ...

Reformat it into a list to make it more easily extensible. While at it, also remove the "plus one of the above" clause because it isn't actually valid.

If we have one reset line per PHY present on the MDIO bus, these automatically become properties of the child PHY nodes. Finally, indicate how the RESET pulse width must be defined, which is the maximum value of all individual PHYs RESET pulse widths determined by reading their datasheets.
