2024-01-09of: Fix double free in of_parse_phandle_with_args_mapChristian A. Ehrhardt
In of_parse_phandle_with_args_map() the inner loop that iterates through the map entries calls of_node_put(new) to free the reference acquired by the previous iteration of the inner loop. This assumes that the value of "new" is NULL on the first iteration of the inner loop. Make sure that this is true in all iterations of the outer loop by setting "new" to NULL after its value is assigned to "cur". Extend the unittest to detect the double free and add an additional test case that actually triggers this path.

2024-01-09Merge tag 'slab-for-6.8' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab Pull slab updates from Vlastimil Babka: - SLUB: delayed freezing of CPU partial slabs (Chengming Zhou) Freezing is an operation involving double_cmpxchg() that makes a slab exclusive for a particular CPU. Chengming noticed that we use it also in situations where we are not yet installing the slab as the CPU slab, because freezing also indicates that the slab is not on the shared list. This results in redundant freeze/unfreeze operation and can be avoided by marking separately the shared list presence by reusing the PG_workingset flag. This approach neatly avoids the issues described in 9b1ea29bc0d7 ("Revert "mm, slub: consider rest of partial list if acquire_slab() fails"") as we can now grab a slab from the shared list in a quick and guaranteed way without the cmpxchg_double() operation that amplifies the lock contention and can fail. As a result, lkp has reported 34.2% improvement of stress-ng.rawudp.ops_per_sec - SLAB removal and SLUB cleanups (Vlastimil Babka) The SLAB allocator has been deprecated since 6.5 and nobody has objected so far. We agreed at LSF/MM to wait until the next LTS, which is 6.6, so we should be good to go now. This doesn't yet erase all traces of SLAB outside of mm/ so some dead code, comments or documentation remain, and will be cleaned up gradually (some series are already in the works). Removing the choice of allocators has already allowed to simplify and optimize the code wiring up the kmalloc APIs to the SLUB implementation. * tag 'slab-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: (34 commits) mm/slub: free KFENCE objects in slab_free_hook() mm/slub: handle bulk and single object freeing separately mm/slub: introduce __kmem_cache_free_bulk() without free hooks mm/slub: fix bulk alloc and free stats mm/slub: optimize free fast path code layout mm/slub: optimize alloc fastpath code layout mm/slub: remove slab_alloc() and __kmem_cache_alloc_lru() wrappers mm/slab: move kmalloc() functions from slab_common.c to slub.c mm/slab: move kmalloc_slab() to mm/slab.h mm/slab: move kfree() from slab_common.c to slub.c mm/slab: move struct kmem_cache_node from slab.h to slub.c mm/slab: move memcg related functions from slab.h to slub.c mm/slab: move pre/post-alloc hooks from slab.h to slub.c mm/slab: consolidate includes in the internal mm/slab.h mm/slab: move the rest of slub_def.h to mm/slab.h mm/slab: move struct kmem_cache_cpu declaration to slub.c mm/slab: remove mm/slab.c and slab_def.h mm/mempool/dmapool: remove CONFIG_DEBUG_SLAB ifdefs mm/slab: remove CONFIG_SLAB code from slab common code cpu/hotplug: remove CPUHP_SLAB_PREPARE hooks ...

2024-01-09dt-bindings: ignore paths outside kernel for DT_SCHEMA_FILESAndré Draszik
If the location of the kernel sources contains the string that we're filtering for using DT_SCHEMA_FILES, then all schemas will currently be matched, returned and checked, not just the ones we actually expected. As an example, if the kernel sources happen to be below a directory 'google', and DT_SCHEMA_FILES=google, everything is checked. More common examples might be having the sources below people's home directories that contain the string st or arm and then searching for those. The list is endless. Fix this by only matching for schemas below the kernel source's bindings directory. Note that I opted for the implementation here so as to not having to deal with escaping DT_SCHEMA_FILES, which would have been the alternative if the grep match itself had been updated.

2024-01-09dt-bindings: tpm: Convert Google Cr50 bindings to DT schemaLukas Wunner
Convert the devicetree bindings for the Google Security Chip H1 running Cr50 firmware to DT schema. The chip can be attached to SPI or I²C. Existing devicetrees use the same "google,cr50" compatible string for both cases without additionally specifying a generic "tcg,tpm_tis-spi" or "tcg,tpm-tis-i2c" compatible. The chip therefore cannot be documented in the tcg,tpm_tis-spi.yaml and tcg,tpm-tis-i2c.yaml schemas: The validator would select both of them and complain about SPI properties when the chip is an I²C peripheral. So document the chip in a schema of its own which includes both, SPI and I²C properties by reference.

2024-01-09dt-bindings: tpm: Consolidate TCG TIS bindingsLukas Wunner
A significant number of Trusted Platform Modules conform to the "TIS" specification published by the Trusted Computing Group ("TCG PC Client Specific TPM Interface Specification"). These chips typically use an SPI, I²C or LPC bus as transport (via MMIO in the latter case). Some of them even support multiple of those buses (selectable through a config strap) or the same chip is available in multiple SKUs, each with a different bus interface. The devicetree bindings for these TPMs have not been converted to DT schema yet and are spread out across 3 generic files and 2 chip-specific files. A few TPM compatible strings were added to trivial-devices.yaml even though additional properties are documented in the plaintext bindings. Consolidate the devicetree bindings into 3 yaml files, one per bus. Move common properties to a separate tpm-common.yaml. Document compatible strings which are supported by the TPM TIS driver but were neglected to be added to the devicetree bindings.

2024-01-09ACPI: resource: Add DMI quirks for ASUS Vivobook E1504GA and E1504GABBen Mayo
Asus Vivobook E1504GA and E1504GAB notebooks are affected by bug #216158 (DSDT specifies the kbd IRQ as level active-low and using the override changes this to rising edge, stopping the keyboard from working). Users of these notebooks do not have a working keyboard unless they add their DMI information to the struct irq1_level_low_skip_override array and compile a custom kernel. Add support for these computers to the Linux kernel without requiring the end-user to recompile the kernel.

There are several rountines in the thermal netlink API that take a thermal zone ID or a thermal zone type as their arguments, but from their callers perspective it would be more convenient to pass a thermal zone pointer to them and let them extract the necessary data from the given thermal zone object by themselves.

While cgroup1 is mostly in maintenance mode, this addition is very small while having an outsized usefulness for users who are still on cgroup1. Yafang also optimized root cgroup list access by making it RCU protected in the process. - Waiman Long optimized rstat operation leading to substantially lower and more consistent lock hold time while flushing the hierarchical statistics. As the lock can be acquired briefly in various hot paths, this reduction has cascading benefits. - Waiman also improved the quality of isolation for cpuset's isolated partitions. CPUs which are allocated to isolated partitions are now excluded from running unbound work items and cpu_is_isolated() test which is used by vmstat and memcg to reduce interference now includes cpuset isolated CPUs. While it isn't there yet, the hope is eventually reaching parity with the isolation level provided by the `isolcpus` boot param but in a dynamic manner. * tag 'cgroup-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: Move rcu_head up near the top of cgroup_root cgroup/cpuset: Include isolated cpuset CPUs in cpu_is_isolated() check cgroup: Avoid false cacheline sharing of read mostly rstat_cpu cgroup/rstat: Optimize cgroup_rstat_updated_list() cgroup: Fix documentation for cpu.idle cgroup/cpuset: Expose cpuset.cpus.isolated workqueue: Move workqueue_set_unbound_cpumask() and its helpers inside CONFIG_SYSFS cgroup/rstat: Reduce cpu_lock hold time in cgroup_rstat_flush_locked() cgroup/cpuset: Take isolated CPUs out of workqueue unbound cpumask cgroup/cpuset: Keep track of CPUs in isolated partitions selftests/cgroup: Minor code cleanup and reorganization of test_cpuset_prs.sh workqueue: Add workqueue_unbound_exclude_cpumask() to exclude CPUs from wq_unbound_cpumask selftests: cgroup: Fixes a typo in a comment cgroup: Add a new helper for cgroup1 hierarchy cgroup: Add annotation for holding namespace_sem in current_cgns_cgroup_from_root() cgroup: Eliminate the need for cgroup_mutex in proc_cgroup_show() cgroup: Make operations on the cgroup root_list RCU safe cgroup: Remove unnecessary list_empty()
