2024-04-30kunit/fortify: Add memcpy() testsKees Cook1-1/+5
Add fortify tests for memcpy() and memmove(). This can use a similar method to the fortify_panic() replacement, only we can do it for what was the WARN_ONCE(), which can be redefined. Since this is primarily testing the fortify behaviors of the memcpy() and memmove() defenses, the tests for memcpy() and memmove() are identical.

Adding support to attach bpf program for entry and return probe of the same function. This is common use case which at the moment requires to create two kprobe multi links. Adding new BPF_TRACE_KPROBE_SESSION attach type that instructs kernel to attach single link program to both entry and exit probe. It's possible to control execution of the bpf program on return probe simply by returning zero or non zero from the entry bpf program execution to execute or not the bpf program on return probe respectively.

2024-04-30ASoC: Intel: avs: PCM code cleanupMark Brown1-0/+4
Merge series from Cezary Rojewski <[email protected]>: A set of changes that aims to improve readability of cohesiveness of the pcm code for the avs-driver. Start off with a change that synchronizes DAI open/close - DAIs are started up in ascending order yet their shutdown does not follow the scheme - it is done in the ascending order too, rather than desceding one. This patch is a dependency for the next one in line. To align the HDAudio DAI startup/shutdown with the non-HDAudio equivalents, relocate the code from component to DAI. The reason above is a dependency stems from codec driver requirements - HDAudio code found in sound/pci/hda/ expects substream->runtime->private_data to point to a valid stream (HOST) pointer. With the hard part done, the follow up changes update the existing code to reduce it is complexity - removal of duplicates, renaming of ambiguous functions and adding new fields to DAI-data object so that the number of local variables and casts is reduced.

2024-04-30net/smc: add operations to merge sndbuf with peer DMBWen Gu1-0/+3
In some scenarios using Emulated-ISM device, sndbuf can share the same physical memory region with peer DMB to avoid data copy from one side to the other. In such case the sndbuf is only a descriptor that describes the shared memory and does not actually occupy memory, it's more like a ghost buffer. +----------+ +----------+ | socket A | | socket B | +----------+ +----------+ | | +--------+ +--------+ | sndbuf | | DMB | | desc | | desc | +--------+ +--------+ | | | +----v-----+ +--------------------------> memory | +----------+ So here introduces three new SMC-D device operations to check if this feature is supported by device, and to {attach|detach} ghost sndbuf to peer DMB.

https://anongit.freedesktop.org/git/drm/drm-intel into drm-next UAPI Changes: - drm/i915/guc: Use context hints for GT frequency Allow user to provide a low latency context hint. When set, KMD sends a hint to GuC which results in special handling for this context. SLPC will ramp the GT frequency aggressively every time it switches to this context. The down freq threshold will also be lower so GuC will ramp down the GT freq for this context more slowly. We also disable waitboost for this context as that will interfere with the strategy. We need to enable the use of SLPC Compute strategy during init, but it will apply only to contexts that set this bit during context creation. Userland can check whether this feature is supported using a new param- I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission enabled platforms as they use SLPC for frequency management. The Mesa usage model for this flag is here - https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint - drm/i915/gt: Enable only one CCS for compute workload Enable only one CCS engine by default with all the compute sices allocated to it. While generating the list of UABI engines to be exposed to the user, exclude any additional CCS engines beyond the first instance *** NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by default to mitigate a hardware bug. All the EUs will still remain usable, and all the userspace drivers have been confirmed to be able to dynamically detect the change in number of CCS engines and adjust. For the smaller percent of applications that get perf benefit from letting the userspace driver dispatch across all 4 CCS engines we will be introducing a sysfs control as a later patch to choose 4 CCS each with 25% EUs (or 50% if 2 CCS).

Inclusion of the header linux/btf_ids.h relies on indirect inclusion of the header linux/types.h. Including it directly on the top level helps to avoid potential problems if linux/types.h hasn't been included before. The main motivation to introduce this it is to avoid similar problems that have shown up in the bpftool where GNU libc indirectly pulls linux/types.h causing compile error of the form: error: unknown type name 'u32' u32 cnt; ^~~ The bpftool compile error was fixed in 62248b22d01e ("tools/resolve_btfids: fix build with musl libc").

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.10 1. Support for handling notification pending interrupt(NPI) The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: - A guest/VM running under a hypervisor(normal world usecase) - An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase) Also, when the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. These changes include skipping of creation of notification bitmaps, some refactoring around schedule receiver interrupt(SRI) handling and addition of support for NPI. 2. Support for FF-A indirect messaging The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint and inform the scheduler that the receiver endpoint must be run. Apart from these two main features, there is an optimisation to avoid queuing of a work when already running on the worker queue. * tag 'ffa-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Avoid queuing work when running on the worker queue firmware: arm_ffa: Fix memory corruption in ffa_msg_send2() firmware: arm_ffa: Add support for FFA_MSG_SEND2 firmware: arm_ffa: Stash the partition properties for query purposes firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPI firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support firmware: arm_ffa: Skip creation of the notification bitmaps Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister * tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: pinctrl: Implementation of the generic scmi-pinctrl driver firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor firmware: arm_scmi: Add support for multiple vendors custom protocols dt-bindings: firmware: arm,scmi: Update examples for protocol@13 firmware: arm_scmi: Avoid non-constant printk format strings firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Add helper to trace bad messages include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Log the perf domain names in the error paths Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.10 The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance. The handling of download mode bits is updated to not attempt QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is specified, and that path is changed to perform a read-modify-write to avoid updating unrelated bits. Error handling is corrected in the peripheral authentication service (PAS) functions, to release interconnect bandwidth votes in the case of an error. An unwanted error print on allocation error is also removed from this code path. The QSEECOM allow list is marked __maybe_unused to avoid build warnings when built with !OF. The error handling related to the interconnect API is cleaned up to avoid handling the impossible IS_ERR() condition. initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent drivers like regulators, interconnects and clocks are registered at this level. Another attempt is made to remove the strncpy() usage in cmd-db, this time with strtomem_pad() which has the correct characteristics. The bwmon regmap cache is changed to maple tree. After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers, the intention of not having them automatically load is documented. Operations on the pmic_glink client list is put under mutual exclusion, to avoid races when clients are being registered. pmic_glink client registered after the firmware notification arrived was not informed that the firmware was up, this is resolved. More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver. Checks for in-flight regulator requests in the RPMh RSC driver is improved to deal with the fact that these occupy multiple registers, so it's insufficient to just to direct address comparison. The socinfo drivers learns about X1 Elite and SMB2360 PMIC. The maintainers entry is split between the linux-arm-msm list and subset that is maintained in the qcom-soc tree, to avoid some confusion about maintainership. * tag 'qcom-drivers-for-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (21 commits) soc: qcom: cmd-db: replace deprecated strncpy with strtomem soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request firmware: qcom: scm: Modify only the download bits in TCSR register firmware: qcom: scm: Fix __scm and waitq completion variable initialization firmware: qcom: scm: Rework dload mode availability check firmware: qcom: scm: Remove redundant scm argument from qcom_scm_waitq_wakeup() firmware: qcom: scm: Remove log reporting memory allocation failure soc: qcom: pmic_glink: notify clients about the current state soc: qcom: pmic_glink: don't traverse clients list without a lock soc: qcom: mention intentionally broken module autoloading firmware: qcom: qcm: fix unused qcom_scm_qseecom_allowlist MAINTAINERS: Split Qualcomm SoC and linux-arm-msm entries soc: qcom: qcom_stats: Add DSPs and apss subsystem stats dt-bindings: soc: qcom: qcom,pmic-glink: document QCM6490 compatible soc: qcom: socinfo: Add SMB2360 PMIC soc: qcom: socinfo: Add X1E80100 SoC ID table entry dt-bindings: arm: qcom,ids: Add SoC ID for X1E80100 soc: qcom: Update init level to core_initcall() for cmd-db and rpmh-rsc soc: qcom: icc-bwmon: Convert to use maple tree register cache firmware: qcom_scm: remove IS_ERR() checks from qcom_scm_bw_{en,dis}able() ...

git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/drivers STM32 Firewall bus for v6.10, round 1 Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. * tag 'stm32-bus-firewall-for-v6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32: bus: stm32_firewall: fix off by one in stm32_firewall_get_firewall() bus: etzpc: introduce ETZPC firewall controller driver bus: rifsc: introduce RIFSC firewall controller driver of: property: fw_devlink: Add support for "access-controller" firewall: introduce stm32_firewall framework dt-bindings: bus: document ETZPC dt-bindings: bus: document RIFSC dt-bindings: treewide: add access-controllers description dt-bindings: document generic access controllers Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

2024-04-29iio: backend: add API for interface tuningNuno Sa1-0/+36
This is in preparation for supporting interface tuning in one for the devices using the axi-adc backend. The new added interfaces are all needed for that calibration: * iio_backend_test_pattern_set(); * iio_backend_chan_status(); * iio_backend_iodelay_set(); * iio_backend_data_sample_trigger(). Interface tuning is the process of going through a set of known points (typically by the frontend), change some clk or data delays (or both) and send/receive some known signal (so called test patterns in this change). The receiving end (either frontend or the backend) is responsible for validating the signal and see if it's good or not. The goal for all of this is to come up with ideal delays at the data interface level so we can have a proper, more reliable data transfer. Also note that for some devices we can change the sampling rate (which typically means changing some reference clock) and that can affect the data interface. In that case, it's import to run the tuning algorithm again as the values we had before may no longer be the best (or even valid) ones.

To new helper is a 1:1 copy of the kxcjk-1013.c version, the only change is the addition of a "char *acpi_method" parameter since some bmc150 dual-accel setups (360° hinges with 1 accel in kbd/base + 1 in display) declare both accels in a single ACPI device with 2 different method names for the 2 matrices. This new acpi_method parameter is not "const char *" because the pathname parameter to acpi_evaluate_object() is not const.

2024-04-29netfs: Replace PG_fscache by setting folio->private and marking dirtyDavid Howells3-12/+36
When dirty data is being written to the cache, setting/waiting on/clearing the fscache flag is always done in tandem with setting/waiting on/clearing the writeback flag. The netfslib buffered write routines wait on and set both flags and the write request cleanup clears both flags, so the fscache flag is almost superfluous. The reason it isn't superfluous is because the fscache flag is also used to indicate that data just read from the server is being written to the cache. The flag is used to prevent a race involving overlapping direct-I/O writes to the cache. Change this to indicate that a page is in need of being copied to the cache by placing a magic value in folio->private and marking the folios dirty. Then when the writeback code sees a folio marked in this way, it only writes it to the cache and not to the server. If a folio that has this magic value set is modified, the value is just replaced and the folio will then be uplodaded too. With this, PG_fscache is no longer required by the netfslib core, 9p and afs. Ceph and nfs, however, still need to use the old PG_fscache-based tracking. To deal with this, a flag, NETFS_ICTX_USE_PGPRIV2, now has to be set on the flags in the netfs_inode struct for those filesystems. This reenables the use of PG_fscache in that inode. 9p and afs use the netfslib write helpers so get switched over; cifs, for the moment, does page-by-page manual access to the cache, so doesn't use PG_fscache and is unaffected.
