2024-07-09misc: keba: Fix missing AUXILIARY_BUS dependencyGerhard Engleder
The cp500 driver creates auxiliary devices. Kernel configs without CONFIG_AUXILIARY_BUS lead to warnings like this: cp500.c: undefined reference to `auxiliary_device_init' cp500.c: undefined reference to `__auxiliary_device_add' Add missing dependency to AUXILIARY_BUS to KEBA_CP500 Kconfig.

2024-07-09iommufd/selftest: Add coverage for IOPF testLu Baolu
Extend the selftest tool to add coverage of testing IOPF handling. This would include the following tests: - Allocating and destroying an iommufd fault object. - Allocating and destroying an IOPF-capable HWPT. - Attaching/detaching/replacing an IOPF-capable HWPT on a device. - Triggering an IOPF on the mock device. - Retrieving and responding to the IOPF through the file interface.

2024-07-09iommufd: Associate fault object with iommufd_hw_pgtableLu Baolu
When allocating a user iommufd_hw_pagetable, the user space is allowed to associate a fault object with the hw_pagetable by specifying the fault object ID in the page table allocation data and setting the IOMMU_HWPT_FAULT_ID_VALID flag bit. On a successful return of hwpt allocation, the user can retrieve and respond to page faults by reading and writing the file interface of the fault object. Once a fault object has been associated with a hwpt, the hwpt is iopf-capable, indicated by hwpt->fault is non NULL. Attaching, detaching, or replacing an iopf-capable hwpt to an RID or PASID will differ from those that are not iopf-capable.

2024-07-09iommufd: Fault-capable hwpt attach/detach/replaceLu Baolu
Add iopf-capable hw page table attach/detach/replace helpers. The pointer to iommufd_device is stored in the domain attachment handle, so that it can be echo'ed back in the iopf_group. The iopf-capable hw page tables can only be attached to devices that support the IOMMU_DEV_FEAT_IOPF feature. On the first attachment of an iopf-capable hw_pagetable to the device, the IOPF feature is enabled on the device. Similarly, after the last iopf-capable hwpt is detached from the device, the IOPF feature is disabled on the device. The current implementation allows a replacement between iopf-capable and non-iopf-capable hw page tables. This matches the nested translation use case, where a parent domain is attached by default and can then be replaced with a nested user domain with iopf support.

2024-07-09iommufd: Add iommufd fault objectLu Baolu
An iommufd fault object provides an interface for delivering I/O page faults to user space. These objects are created and destroyed by user space, and they can be associated with or dissociated from hardware page table objects during page table allocation or destruction. User space interacts with the fault object through a file interface. This interface offers a straightforward and efficient way for user space to handle page faults. It allows user space to read fault messages sequentially and respond to them by writing to the same file. The file interface supports reading messages in poll mode, so it's recommended that user space applications use io_uring to enhance read and write efficiency. A fault object can be associated with any iopf-capable iommufd_hw_pgtable during the pgtable's allocation. All I/O page faults triggered by devices when accessing the I/O addresses of an iommufd_hw_pgtable are routed through the fault object to user space. Similarly, user space's responses to these page faults are routed back to the iommu device driver through the same fault object.

2024-07-09iommufd: Add fault and response message definitionsLu Baolu
iommu_hwpt_pgfaults represent fault messages that the userspace can retrieve. Multiple iommu_hwpt_pgfaults might be put in an iopf group, with the IOMMU_PGFAULT_FLAGS_LAST_PAGE flag set only for the last iommu_hwpt_pgfault. An iommu_hwpt_page_response is a response message that the userspace should send to the kernel after finishing handling a group of fault messages. The @dev_id, @pasid, and @grpid fields in the message identify an outstanding iopf group for a device. The @cookie field, which matches the cookie field of the last fault in the group, will be used by the kernel to look up the pending message.

2024-07-09spi: mux: set ctlr->bits_per_word_maskDavid Lechner
Like other SPI controller flags, bits_per_word_mask may be used by a peripheral driver, so it needs to reflect the capabilities of the underlying controller.

2024-07-09spi: add defer_optimize_message controller flagDavid Lechner
Adding spi_optimize_message() broke the spi-mux driver because it calls spi_async() from it's transfer_one_message() callback. This resulted in passing an incorrectly optimized message to the controller. For example, if the underlying controller has an optimize_message() callback, this would have not been called and can cause a crash when the underlying controller driver tries to transfer the message. Also, since the spi-mux driver swaps out the controller pointer by replacing msg->spi, __spi_unoptimize_message() was being called with a different controller than the one used in __spi_optimize_message(). This could cause a crash when attempting to free the message resources when __spi_unoptimize_message() is called in spi_finalize_current_message() since it is being called with a controller that did not allocate the resources. This is fixed by adding a defer_optimize_message flag for controllers. This flag causes all of the spi_[maybe_][un]optimize_message() calls to be a no-op (other than attaching a pointer to the spi device to the message). This allows the spi-mux driver to pass an unmodified message to spi_async() in spi_mux_transfer_one_message() after the spi device has been swapped out. This causes __spi_optimize_message() and __spi_unoptimize_message() to be called only once per message and with the correct/same controller in each case.

2024-07-09spi: don't unoptimize message in spi_async()David Lechner

This can corrupt the message while it is being used by the controller driver. spi_maybe_unoptimize_message() is already called in the correct place in spi_finalize_current_message() to balance the call to spi_maybe_optimize_message() in spi_async().

2024-07-09thermal: intel: hfi: Give HFI instances package scopeZhang Rui
The Intel Software Developer's Manual defines the scope of HFI (registers and memory buffer) as a package. Use package scope(*) in the software representation of an HFI instance. Using die scope in HFI instances has the effect of creating multiple conflicting instances for the same package: each instance allocates its own memory buffer and configures the same package-level registers. Specifically, only one of the allocated memory buffers can be set in the MSR_IA32_HW_FEEDBACK_PTR register. CPUs get incorrect HFI data from the table. The problem does not affect current HFI-capable platforms because they all have single-die processors. (*) We used die scope for HFI instances because there had been processors with packages enumerated as dies. None of those systems supported HFI, though. If such a system emerged, it would need to be quirked.

2024-07-09USB: serial: mos7840: fix crash on resumeDmitry Smirnov
Since commit c49cfa917025 ("USB: serial: use generic method if no alternative is provided in usb serial layer"), USB serial core calls the generic resume implementation when the driver has not provided one. This can trigger a crash on resume with mos7840 since support for multiple read URBs was added back in 2011. Specifically, both port read URBs are now submitted on resume for open ports, but the context pointer of the second URB is left set to the core rather than mos7840 port structure. Fix this by implementing dedicated suspend and resume functions for mos7840. Tested with Delock 87414 USB 2.0 to 4x serial adapter.

The main changes are: 1) Support resilient split BTF which cuts down on duplication and makes BTF as compact as possible wrt BTF from modules, from Alan Maguire & Eduard Zingerman. 2) Add support for dumping kfunc prototypes from BTF which enables both detecting as well as dumping compilable prototypes for kfuncs, from Daniel Xu. 3) Batch of s390x BPF JIT improvements to add support for BPF arena and to implement support for BPF exceptions, from Ilya Leoshkevich. 4) Batch of riscv64 BPF JIT improvements in particular to add 12-argument support for BPF trampolines and to utilize bpf_prog_pack for the latter, from Pu Lehui. 5) Extend BPF test infrastructure to add a CHECKSUM_COMPLETE validation option for skbs and add coverage along with it, from Vadim Fedorenko. 6) Inline bpf_get_current_task/_btf() helpers in the arm64 BPF JIT which gives a small 1% performance improvement in micro-benchmarks, from Puranjay Mohan. 7) Extend the BPF verifier to track the delta between linked registers in order to better deal with recent LLVM code optimizations, from Alexei Starovoitov. 8) Fix bpf_wq_set_callback_impl() kfunc signature where the third argument should have been a pointer to the map value, from Benjamin Tissoires. 9) Extend BPF selftests to add regular expression support for test output matching and adjust some of the selftest when compiled under gcc, from Cupertino Miranda. 10) Simplify task_file_seq_get_next() and remove an unnecessary loop which always iterates exactly once anyway, from Dan Carpenter. 11) Add the capability to offload the netfilter flowtable in XDP layer through kfuncs, from Florian Westphal & Lorenzo Bianconi. 12) Various cleanups in networking helpers in BPF selftests to shave off a few lines of open-coded functions on client/server handling, from Geliang Tang. 13) Properly propagate prog->aux->tail_call_reachable out of BPF verifier, so that x86 JIT does not need to implement detection, from Leon Hwang. 14) Fix BPF verifier to add a missing check_func_arg_reg_off() to prevent an out-of-bounds memory access for dynpointers, from Matt Bobrowski. 15) Fix bpf_session_cookie() kfunc to return __u64 instead of long pointer as it might lead to problems on 32-bit archs, from Jiri Olsa. 16) Enhance traffic validation and dynamic batch size support in xsk selftests, from Tushar Vyavahare. bpf-next-for-netdev * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (102 commits) selftests/bpf: DENYLIST.aarch64: Remove fexit_sleep selftests/bpf: amend for wrong bpf_wq_set_callback_impl signature bpf: helpers: fix bpf_wq_set_callback_impl signature libbpf: Add NULL checks to bpf_object__{prev_map,next_map} selftests/bpf: Remove exceptions tests from DENYLIST.s390x s390/bpf: Implement exceptions s390/bpf: Change seen_reg to a mask bpf: Remove unnecessary loop in task_file_seq_get_next() riscv, bpf: Optimize stack usage of trampoline bpf, devmap: Add .map_alloc_check selftests/bpf: Remove arena tests from DENYLIST.s390x selftests/bpf: Add UAF tests for arena atomics selftests/bpf: Introduce __arena_global s390/bpf: Support arena atomics s390/bpf: Enable arena s390/bpf: Support address space cast instruction s390/bpf: Support BPF_PROBE_MEM32 s390/bpf: Land on the next JITed instruction after exception s390/bpf: Introduce pre- and post- probe functions s390/bpf: Get rid of get_probe_mem_regno() ... ==================== Link: https://patch.msgid.link/20240708221438.10974-1-daniel@iogearbox.net Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-07-09s390/mm: Add NULL pointer check to crst_table_free() base_crst_free()Heiko Carstens
crst_table_free() used to work with NULL pointers before the conversion to ptdescs. Since crst_table_free() can be called with a NULL pointer (error handling in crst_table_upgrade() add an explicit check. Also add the same check to base_crst_free() for consistency reasons. In real life this should not happen, since order two GFP_KERNEL allocations will not fail, unless FAIL_PAGE_ALLOC is enabled and used.
