Pull devicetree updates from Rob Herring: "DT core: - Add support for generating DT nodes for PCI devices. This is the groundwork for applying overlays to PCI devices containing non-discoverable downstream devices. - DT unittest additions to check reverted changesets, to test for refcount issues, and to test unresolved symbols. Also, various clean-ups of the unittest along the way. - Refactor node and property manipulation functions to better share code with old API and changeset API - Refactor changeset print functions to a common implementation - Move some platform_device specific functions into of_platform.c Bindings: - Treewide fixing of typos - Treewide clean-up of SPDX tags to use 'OR' consistently - Last chunk of dropping unnecessary quotes.

Pull ARM SoC driver updates from Arnd Bergmann: "The main change this time was the introduction of the drivers/genpd subsystem that gets split out from drivers/soc to keep common functionality together. The SCMI driver subsystem gets an update to version 3.2 of the specification. There are also updates to memory, reset and other firmware drivers. On the soc driver side, the updates are mostly cleanups across a number of Arm platforms.

Intel CPUs ship with ERMS for over a decade, but this is not true for AMD. In particular one reasonably recent uarch (EPYC 7R13) does not have it (or at least the bit is inactive when running on the Amazon EC2 cloud -- I found rather conflicting information about AMD CPUs vs the extension). Hand-rolled mov loops executing in this case are quite pessimal compared to rep movsq for bigger sizes. While the upper limit depends on uarch, everyone is well south of 1KB AFAICS and sizes bigger than that are common. While technically ancient CPUs may be suffering from rep usage, gcc has been emitting it for years all over kernel code, so I don't think this is a legitimate concern. Sample result from read1_processes from will-it-scale (4KB reads/s): before: 1507021 after: 1721828 (+14%) Note that the cutoff point for rep usage is set to 64 bytes, which is way too conservative but I'm sticking to what was done in 47ee3f1d ("x86: re-introduce support for ERMS copies for user space accesses"). That is to say *some* copies will now go slower, which is fixable but beyond the scope of this patch.

Pull LSM updates from Paul Moore: - Add proper multi-LSM support for xattrs in the security_inode_init_security() hook Historically the LSM layer has only allowed a single LSM to add an xattr to an inode, with IMA/EVM measuring that and adding its own as well. As we work towards promoting IMA/EVM to a "proper LSM" instead of the special case that it is now, we need to better support the case of multiple LSMs each adding xattrs to an inode and after several attempts we now appear to have something that is working well. It is worth noting that in the process of making this change we uncovered a problem with Smack's SMACK64TRANSMUTE xattr which is also fixed in this pull request. - Additional LSM hook constification Two patches to constify parameters to security_capget() and security_binder_transfer_file(). While I generally don't make a special note of who submitted these patches, these were the work of an Outreachy intern, Khadija Kamran, and that makes me happy; hopefully it does the same for all of you reading this. - LSM hook comment header fixes One patch to add a missing hook comment header, one to fix a minor typo. - Remove an old, unused credential function declaration It wasn't clear to me who should pick this up, but it was trivial, obviously correct, and arguably the LSM layer has a vested interest in credentials so I merged it.

Pull selinux updates from Paul Moore: "Thirty three SELinux patches, which is a pretty big number for us, but there isn't really anything scary in here; in fact we actually manage to remove 10 lines of code with this :) - Promote the SELinux DEBUG_HASHES macro to CONFIG_SECURITY_SELINUX_DEBUG The DEBUG_HASHES macro was a buried SELinux specific preprocessor debug macro that was a problem waiting to happen. Promoting the debug macro to a proper Kconfig setting should help both improve the visibility of the feature as well enable improved test coverage. We've moved some additional debug functions under the CONFIG_SECURITY_SELINUX_DEBUG flag and we may see more work in the future. - Emit a pr_notice() message if virtual memory is executable by default As this impacts the SELinux access control policy enforcement, if the system's configuration is such that virtual memory is executable by default we print a single line notice to the console. - Drop avtab_search() in favor of avtab_search_node() Both functions are nearly identical so we removed avtab_search() and converted the callers to avtab_search_node(). - Add some SELinux network auditing helpers The helpers not only reduce a small amount of code duplication, but they provide an opportunity to improve UDP flood performance slightly by delaying initialization of the audit data in some cases. - Convert GFP_ATOMIC allocators to GFP_KERNEL when reading SELinux policy There were two SELinux policy load helper functions that were allocating memory using GFP_ATOMIC, they have been converted to GFP_KERNEL. - Quiet a KMSAN warning in selinux_inet_conn_request() A one-line error path (re)set patch that resolves a KMSAN warning. It is important to note that this doesn't represent a real bug in the current code, but it quiets KMSAN and arguably hardens the code against future changes. - Cleanup the policy capability accessor functions This is a follow-up to the patch which reverted SELinux to using a global selinux_state pointer. This patch cleans up some artifacts of that change and turns each accessor into a one-line READ_ONCE() call into the policy capabilities array. - A number of patches from Christian Göttsche Christian submitted almost two-thirds of the patches in this pull request as he worked to harden the SELinux code against type differences, variable overflows, etc. - Support for separating early userspace from the kernel in policy, with a later revert We did have a patch that added a new userspace initial SID which would allow SELinux to distinguish between early user processes created before the initial policy load and the kernel itself. Unfortunately additional post-merge testing revealed a problematic interaction with an old SELinux userspace on an old version of Ubuntu so we've reverted the patch until we can resolve the compatibility issue. - Remove some outdated comments dealing with LSM hook registration When we removed the runtime disable functionality we forgot to remove some old comments discussing the importance of LSM hook registration ordering. - Minor administrative changes Stephen Smalley updated his email address and "debranded" SELinux from "NSA SELinux" to simply "SELinux".

Pull audit updates from Paul Moore: "Six audit patches, the highlights are: - Add an explicit cond_resched() call when generating PATH records Certain tracefs/debugfs operations can generate a *lot* of audit PATH entries and if one has an aggressive system configuration (not the default) this can cause a soft lockup in the audit code as it works to process all of these new entries. This is in sharp contrast to the common case where only one or two PATH entries are logged. In order to fix this corner case without excessively impacting the common case we're adding a single cond_rescued() call between two of the most intensive loops in the __audit_inode_child() function. - Various minor cleanups We removed a conditional header file as the included header already had the necessary logic in place, fixed a dummy function's return value, and the usual collection of checkpatch.pl noise (whitespace, brace, and trailing statement tweaks)" * tag 'audit-pr-20230829' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: move trailing statements to next line audit: cleanup function braces and assignment-in-if-condition audit: add space before parenthesis and around '=', "==", and '<' audit: fix possible soft lockup in __audit_inode_child() audit: correct audit_filter_inodes() definition audit: include security.h unconditionally

Pull sysctl updates from Luis Chamberlain: "Long ago we set out to remove the kitchen sink on kernel/sysctl.c arrays and placings sysctls to their own sybsystem or file to help avoid merge conflicts. Matthew Wilcox pointed out though that if we're going to do that we might as well also *save* space while at it and try to remove the extra last sysctl entry added at the end of each array, a sentintel, instead of bloating the kernel by adding a new sentinel with each array moved. Doing that was not so trivial, and has required slowing down the moves of kernel/sysctl.c arrays and measuring the impact on size by each new move. The complex part of the effort to help reduce the size of each sysctl is being done by the patient work of el señor Don Joel Granados. A lot of this is truly painful code refactoring and testing and then trying to measure the savings of each move and removing the sentinels. Although Joel already has code which does most of this work, experience with sysctl moves in the past shows is we need to be careful due to the slew of odd build failures that are possible due to the amount of random Kconfig options sysctls use. To that end Joel's work is split by first addressing the major housekeeping needed to remove the sentinels, which is part of this merge request. The rest of the work to actually remove the sentinels will be done later in future kernel releases. The preliminary math is showing this will all help reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array where we are able to remove each sentinel in the future. That also means there is no more bloating the kernel with the extra ~64 bytes per array moved as no new sentinels are created" * tag 'sysctl-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: sysctl: Use ctl_table_size as stopping criteria for list macro sysctl: SIZE_MAX->ARRAY_SIZE in register_net_sysctl vrf: Update to register_net_sysctl_sz networking: Update to register_net_sysctl_sz netfilter: Update to register_net_sysctl_sz ax.25: Update to register_net_sysctl_sz sysctl: Add size to register_net_sysctl function sysctl: Add size arg to __register_sysctl_init sysctl: Add size to register_sysctl sysctl: Add a size arg to __register_sysctl_table sysctl: Add size argument to init_header sysctl: Add ctl_table_size to ctl_table_header sysctl: Use ctl_table_header in list_for_each_table_entry sysctl: Prefer ctl_table_header in proc_sysctl

Pull modules updates from Luis Chamberlain: "Summary of the changes worth highlighting from most interesting to boring below: - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the protection he put in place in year 2020 to prevent proprietary modules from using GPL only symbols, and also ensuring proprietary modules which export symbols grandfather their taint. That was done through year 2020 commit 262e6ae7 ("modules: inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by clarifing __symbol_get() was only ever intended to prevent module reference loops by Linux kernel modules and so making it only find symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic used by Nvidia was to use symbol_get() to purposely swift through proprietary module symbols and completely bypass our traditional EXPORT_SYMBOL*() annotations and community agreed upon restrictions. A small set of preamble patches fix up a few symbols which just needed adjusting for this on two modules, the rtc ds1685 and the networking enetc module. Two other modules just needed some build fixing and removal of use of __symbol_get() as they can't ever be modular, as was done by Arnd on the ARM pxa module and Christoph did on the mmc au1xmmc driver. This is a good reminder to us that symbol_get() is just a hack to address things which should be fixed through Kconfig at build time as was done in the later patches, and so ultimately it should just go. - Extremely late minor fix for old module layout 055f23b7 ("module: check for exit sections in layout_sections() instead of module_init_section()") by James Morse for arm64. Note that this layout thing is old, it is *not* Song Liu's commit ac3b4328 ("module: replace module_layout with module_memory"). The issue however is very odd to run into and so there was no hurry to get this in fast. - Although the fix did not go through the modules tree I'd like to highlight the fix by Peter Zijlstra in commit 54097309 ("x86/static_call: Fix __static_call_fixup()") now merged in your tree which came out of what was originally suspected to be a fallout of the the newer module layout changes by Song Liu commit ac3b4328 ("module: replace module_layout with module_memory") instead of module_init_section()"). Thanks to the report by Christian Bricart and the debugging by Song Liu & Peter that turned to be noted as a kernel regression in place since v5.19 through commit ee88d363 ("x86,static_call: Use alternative RET encoding"). I highlight this to reflect and clarify that we haven't seen more fallout from ac3b4328 ("module: replace module_layout with module_memory"). - RISC-V toolchain got mapping symbol support which prefix symbols with "$" to help with alignment considerations for disassembly. This is used to differentiate between incompatible instruction encodings when disassembling. RISC-V just matches what ARM/AARCH64 did for alignment considerations and Palmer Dabbelt extended is_mapping_symbol() to accept these symbols for RISC-V. We already had support for this for all architectures but it also checked for the second character, the RISC-V check Dabbelt added was just for the "$". After a bit of testing and fallout on linux-next and based on feedback from Masahiro Yamada it was decided to simplify the check and treat the first char "$" as unique for all architectures, and so we no make is_mapping_symbol() for all archs if the symbol starts with "$". The most relevant commit for this for RISC-V on binutils was: https://sourceware.org/pipermail/binutils/2021-July/117350.html - A late fix by Andrea Righi (today) to make module zstd decompression use vmalloc() instead of kmalloc() to account for large compressed modules. I suspect we'll see similar things for other decompression algorithms soon. - samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and Chen Jiahao" * tag 'modules-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module/decompress: use vmalloc() for zstd decompression workspace kallsyms: Add more debug output for selftest ARM: module: Use module_init_layout_section() to spot init sections arm64: module: Use module_init_layout_section() to spot init sections module: Expose module_init_layout_section() modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules rtc: ds1685: use EXPORT_SYMBOL_GPL for ds1685_rtc_poweroff net: enetc: use EXPORT_SYMBOL_GPL for enetc_phc_index mmc: au1xmmc: force non-modular build and remove symbol_get usage ARM: pxa: remove use of symbol_get() samples/hw_breakpoint: mark sample_hbp as static samples/hw_breakpoint: fix building without module unloading samples/hw_breakpoint: Fix kernel BUG 'invalid opcode: 0000' modpost, kallsyms: Treat add '$'-prefixed symbols as mapping symbols kernel: params: Remove unnecessary ‘0’ values from err module: Ignore RISC-V mapping symbols too

Pull slab updates from Vlastimil Babka: "This happens to be a small one (due to summer I guess), and all hardening related: - Randomized kmalloc caches, by GONG, Ruiqi. A new opt-in hardening feature to make heap spraying harder. It creates multiple (16) copies of kmalloc caches, reducing the chance of an attacker-controllable allocation site to land in the same slab as e.g. an allocation site with use-after-free vulnerability. The selection of the copy is derived from the allocation site address, including a per-boot random seed. - Stronger typing for hardened freelists in SLUB, by Jann Horn Introduces a custom type for hardened freelist entries instead of "void *" as those are not directly dereferencable. While reviewing this, I've noticed opportunities for further cleanups in that code and added those on top" * tag 'slab-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: Randomized slab caches for kmalloc() mm/slub: remove freelist_dereference() mm/slub: remove redundant kasan_reset_tag() from freelist_ptr calculations mm/slub: refactor freelist to use custom type

Since commit 3d5089c4 ("of/address: Add support for 3 address cell bus"), the DT address functions can handle translating buses with 3 address cells. Replace the custom code with the for_each_of_range() iterator. The original code had fallbacks to get "#address-cells"/"#size-cells" from the bus parent node if they are missing. This is non-standard behavior, and AFAICT the upstream .dts files never relied on that.
