optee: Fix a NULL vs IS_ERR() check
The tee_shm_get_va() function never returns NULL, it returns error
pointers. Update the check to match.

optee: add RPMB dependency
Prevent build error when CONFIG_RPMB=m and CONFIG_OPTEE=y by adding a
dependency to CONFIG_RPMB for CONFIG_OPTEE so the RPMB subsystem always
is reachable if configured. This means that CONFIG_OPTEE automatically
becomes compiled as a module if CONFIG_RPMB is compiled as a module. If
CONFIG_RPMB isn't configured or is configured as built-in, CONFIG_OPTEE
will remain unchanged.

optee: probe RPMB device using RPMB subsystem
Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and use an RPMB device via the RPMB subsystem instead of passing the RPMB frames via tee-supplicant in user space. A fallback mechanism is kept to route RPMB frames via tee-supplicant if the RPMB subsystem isn't available. The OP-TEE RPC ABI is extended to support iterating over all RPMB devices until one is found with the expected RPMB key already programmed.

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

soc: driver updates for 6.11
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are farily small maintenance changes, either addressing minor mistakes or enabling additional hardware. The qualcomm platform changes add a number of features and are larger than the other ones combined, introducing the use of linux/cleanup.h across several drivers, adding support for Snapdragon X1E and other SoCs in platform drivers, a new "protection domain mapper" driver, and a "shared memory bridge" driver. The cznic "turris omnia" router based on Marvell Armada gets a platform driver that talks to the board specific microcontroller. The reset and cache subsystems get a few minor updates to SoC specific drivers, while the ff-a, scmi and optee firmware drivers get some code refactoring and new features. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmaVTTUACgkQYKtH/8kJ UiegixAAqGfwUtwk2GGZJlEGjUjT4cqrwCTLhNlaNfgN/dZxjk1XBTKvtp2mVDi2 lJN8TNqa0Csw8XZYPgHi0s1ppmwQl07Unpbc9tUeS4tAeIuputDe+ia0UtQx3Mkd GTAKJO6VzLeCnDxB4757OURZO9wYlPdZycQbnSKDyfBIapFuZwozmbAc7BuFGvBv 2Zt5lca531EJuM5wg25f+F/8XSxZIqjMA6/PTGNCYig1bx5AM2tCWK2xN+BL+dxn YVLuRZT7lSgpwivg9OHzJ49g9WeJB7RArnSDg1Ac7sNfC8476UC17BAH4rF7QSTP q2GBP2VOdRJA9mJkavtLhE/1LPDJuYTM+nt1xq7jzG2MKN7yLjX0LMrMgKsk0pXZ T2qQh7+4MA9lwlpGEwDruMajTJahbMgiAUcSivLsr18LrifAnKVHBDTRmRwNiRX2 T3/zk90kenJX1NOkc4SrdLd5iCyq0oSN+fukdh3UMgJLnAzaWOe5mKAMF7eefeog rMH276W8JwbbmIC4R2aQm6TL7IWBtaCaHuLqYOiTjooir31OgwW4Mztd7okU4v4I rOGhV0zJTSVXT+a4O2jOooWppS9xE45/F2DSigSvZjEiahZ0L4feaOrHui5PVVlW wmFmobCq6Y0Mjspdk64O1tbUWJ17CmRK1WDrUUk0VgmLy9gn6A8= =ChcR -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are fairly small maintenance changes, either addressing minor mistakes or enabling additional hardware.

driver core: have match() callback in struct bus_type take a const *
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

TEE driver for Trusted Services
This introduces a TEE driver for Trusted Services [1]. Trusted Services is a TrustedFirmware.org project that provides a framework for developing and deploying device Root of Trust services in FF-A [2] Secure Partitions. The project hosts the reference implementation of Arm Platform Security Architecture [3] for Arm A-profile devices. The FF-A Secure Partitions are accessible through the FF-A driver in Linux. However, the FF-A driver doesn't have a user space interface so user space clients currently cannot access Trusted Services. The goal of this TEE driver is to bridge this gap and make Trusted Services functionality accessible from user space.

tee: tstee: Add Trusted Services TEE driver
The Trusted Services project provides a framework for developing and deploying device Root of Trust services in FF-A Secure Partitions. The FF-A SPs are accessible through the FF-A driver, but this doesn't provide a user space interface. The goal of this TEE driver is to make Trusted Services SPs accessible for user space clients. All TS SPs have the same FF-A UUID, it identifies the RPC protocol used by TS. A TS SP can host one or more services, a service is identified by its service UUID. The same type of service cannot be present twice in the same SP. During SP boot each service in an SP is assigned an interface ID, this is just a short ID to simplify message addressing. There is 1:1 mapping between TS SPs and TEE devices, i.e. a separate TEE device is registered for each TS SP. This is required since contrary to the generic TEE design where memory is shared with the whole TEE implementation, in case of FF-A, memory is shared with a specific SP. A user space client has to be able to separately share memory with each SP based on its endpoint ID.

tee: optee: Move pool_op helper functions
Move the pool alloc and free helper functions from the OP-TEE driver to the TEE subsystem, since these could be reused in other TEE drivers.

tee: optee: smc: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

ARM: SoC drivers for 6.9
This is the usual mix of updates for drivers that are used on (mostly
ARM) SoCs with no other top-level subsystem tree, including:
- The SCMI firmware subsystem gains support for version 3.2 of the
specification and updates to the notification code.
- Feature updates for Tegra and Qualcomm platforms for added
hardware support.
- A number of platforms get soc_device additions for identifying newly
added chips from Renesas, Qualcomm, Mediatek and Google.
- Trivial improvements for firmware and memory drivers amongst
others, in particular 'const' annotations throughout multiple
subsystems.

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to
access.
- Speaking of translations, more of those for Spanish and Chinese.
...plus the usual stream of documentation updates and typo fixes.

tee: Use iov_iter to better support shared buffer registration
Currently it's not possible to register kernel buffers with TEE which are allocated via vmalloc. Use iov_iter and associated helper functions to manage the page registration for all type of memories.

Documentation: Destage TEE subsystem documentation
Add a separate documentation directory for TEE subsystem since it is a standalone subsystem which already offers devices consumed by multiple different subsystem drivers. Split overall TEE subsystem documentation modularly where: - The userspace API has been moved to Documentation/userspace-api/tee.rst. - The driver API has been moved to Documentation/driver-api/tee.rst. - The first module covers the overview of TEE subsystem. - The further modules are dedicated to different TEE implementations like: - OP-TEE - AMD-TEE - and so on for future TEE implementation support.

optee: ffa_abi: add asynchronous notifications
Adds support for asynchronous notifications from OP-TEE in secure world when communicating via FF-A. In principle from OP-TEE and kernel driver point of view this works in the same way as for the SMC ABI based implementation. The OP-TEE FF-A ABI is expanded in OPTEE_FFA_EXCHANGE_CAPABILITIES with the capability OPTEE_FFA_SEC_CAP_ASYNC_NOTIF to indicate that OP-TEE supports asynchronous notifications. OPTEE_FFA_ENABLE_ASYNC_NOTIF is also added to tell that the driver has successfully initialized these notifications. Notification capability is negotiated while the driver is initialized. If both sides supports these notifications then they are enabled. The notification concept in this driver is merged with the FF-A concept, the lower 64 values are reserved for FF-A as asynchronous notifications while the synchronous notifications use the higher values. So a FF-A notification has to be allocated for each discrete asynchronous notification value needed. Only one asynchronous notification value is used at the moment, the "do bottom half" notification.

tee: optee: support tracking system threads
Adds support in the OP-TEE driver to keep track of reserved system threads. The logic allows one OP-TEE thread to be reserved to TEE system sessions. The optee_cq_*() functions are updated to handle this if enabled, that is when TEE describes how many thread context it supports and when at least 1 session has registered as a system session (using tee_client_system_session()). For sake of simplicity, initialization of call queue management is factorized into new helper function optee_cq_init(). The SMC ABI part of the driver enables this tracking, but the FF-A ABI part does not.

tee: system session
Adds kernel client API function tee_client_system_session() for a client to request a system service entry in TEE context. This feature is needed to prevent a system deadlock when several TEE client applications invoke TEE, consuming all TEE thread contexts available in the secure world. The deadlock can happen in the OP-TEE driver for example if all these TEE threads issue an RPC call from TEE to Linux OS to access an eMMC RPMB partition (TEE secure storage) which device clock or regulator controller is accessed through an OP-TEE SCMI services. In that case, Linux SCMI driver must reach OP-TEE SCMI service without waiting until one of the consumed TEE threads is freed.

tee: optee: Fix supplicant based device enumeration
Currently supplicant dependent optee device enumeration only registers
devices whenever tee-supplicant is invoked for the first time. But it
forgets to remove devices when tee-supplicant daemon stops running and
closes its context gracefully. This leads to following error for fTPM
driver during reboot/shutdown:
[ 73.466791] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024
Fix this by adding an attribute for supplicant dependent devices so that
the user-space service can detect and detach supplicant devices before
closing the supplicant:
$ for dev in /sys/bus/tee/devices/*; do if [[ -f "$dev/need_supplicant" && -f "$dev/driver/unbind" ]]; \
then echo $(basename "$dev") > $dev/driver/unbind; fi done

ARM: SoC fixes for 6.6, part 2
AngeloGioacchino Del Regno is stepping in as co-maintainer for the MediaTek SoC platform and starts by sending some dts fixes for the mt8195 platform that had been pending for a while. On the ixp4xx platform, Krzysztof Halasa steps down as co-maintainer, reflecting that Linus Walleij has been handling this on his own for the past few years. Generic RISC-V kernels are now marked as incompatible with the RZ/Five platform that requires custom hacks both for managing its DMA bounce buffers and for addressing low virtual memory. Finally, there is one bugfix for the AMDTEE firmware driver to prevent a use-after-free bug. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmUn5QgACgkQYKtH/8kJ UicWRw/+J+gYuPbjAO5A34KjcvE0/oHoX0CartiJLjGMSboXqjvlJOL2V37q9cTO kt/all/wWYnyvr3L09jPKZY8J9stw6wgMpkPZpcAORkF/Vc8KNEvBBVVnTIZSlie G6HSNW1S3qMPdt2mxjPWeO7aoKqq/lIuQoJDDAh3XQWYowy7++o6TreLs14UsGfv +PRNm5dR+SGe5QC/vIJIn0U7bTD7PRQ7xEdv2LC+ANto+mbtdyVOKh16kcTnzO+2 NUHmBQvHqGS0Q1uN1hiXQocL9WA7vreVLk7ARbq/SLr1ccOsxJrxKj9LYPhoLq68 8oJCHR8RBAXxYInhiw2xR62KczTEVickNWlHR7aiWlQ+Bxha/YhpmUAzh/hrlvWg edCBUSIxQW1CyLmbMxAqyHQn72F+sMM/LulhmftHuBcbF1YwNseAV67MKjoMSTr0 rjSiXpzdomCvgZxhJYujHLjugKh6jfLMRwPx+0P6qKebdm/y1a17kGtUf/NQ24bn nDAeOAKWRRdEu4CjcoYkzVLgE6MlXUiSbSmpsPpDevge1qbcrfHgIATHech4oyDd h2o8xIO37H4QB3s9w18g05OQRToRlBHPMxQhD+vlRy77Zd9BE7wZqKcwR9XjkyyX +qPcNHVN0khxf+/NYiIE/Wn5Z57PL2vvgYoSp2L2Wi+UiYEZ0Ek= =Ukoh -----END PGP SIGNATURE----- Merge tag 'soc-fixes-6.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "AngeloGioacchino Del Regno is stepping in as co-maintainer for the MediaTek SoC platform and starts by sending some dts fixes for the mt8195 platform that had been pending for a while.

tee: amdtee: fix use-after-free vulnerability in amdtee_close_session
There is a potential race condition in amdtee_close_session that may
cause use-after-free in amdtee_open_session. For instance, if a session
has refcount == 1, and one thread tries to free this session via:
kref_put(&sess->refcount, destroy_session);
the reference count will get decremented, and the next step would be to
call destroy_session(). However, if in another thread,
amdtee_open_session() is called before destroy_session() has completed
execution, alloc_session() may return 'sess' that will be freed up
later in destroy_session() leading to use-after-free in
amdtee_open_session.
To fix this issue, treat decrement of sess->refcount and removal of
'sess' from session list in destroy_session() as a critical section, so
that it is executed atomically.

tee: amdtee: Add return_origin to 'struct tee_cmd_load_ta'
After TEE has completed processing of TEE_CMD_ID_LOAD_TA, set proper
value in 'return_origin' argument passed by open_session() call. To do
so, add 'return_origin' field to the structure tee_cmd_load_ta. The
Trusted OS shall update return_origin as part of TEE processing.
This change to 'struct tee_cmd_load_ta' interface requires a similar update
in AMD-TEE Trusted OS's TEE_CMD_ID_LOAD_TA interface.
This patch has been verified on Phoenix Birman setup. On older APUs,
return_origin value will be 0.

Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems.

drivers get notable functionality updates.
Updates on other platforms include:
- Various updates to the Mediatek mutex and mmsys drivers, including
support for the Helio X10 SoC
- Support for unidirectional mailbox channels in Arm SCMI firmware
- Support for per cpu asynchronous notification in OP-TEE firmware
- Minor updates for memory controller drivers.
- Minor updates for Renesas, TI, Amlogic, Apple, Broadcom, Tegra,
Allwinner, Versatile Express, Canaan, Microchip, Mediatek and i.MX
SoC drivers, mainly updating the use of MODULE_LICENSE() macros and
obsolete DT driver interfaces.

optee: fix uninited async notif value
Fixes an uninitialized variable in irq_handler() that could lead to
unpredictable behavior in case OP-TEE fails to handle SMC function ID
OPTEE_SMC_GET_ASYNC_NOTIF_VALUE. This change ensures that in that case
get_async_notif_value() properly reports there are no notification
event.
