Hi,
Just updates and fixes, no major changes. I might send a PR during the release cycle addressing a performance issue in the bus encryption: 1. https://bugzilla.kernel.org/show_bug.cgi?id=219229 2. https://lore.kernel.org/linux-integrity/20240917154444.702370-1-jarkko@kernel.org/ The first version of the patch set cut out already five seconds and I expect similar figures from the current version but I really need some more feedback. However, this week is not exactly optimal for getting it, given the Vienna conference.

But as we started to work on this, we found lots of interesting issues in the shared code and infrastructure, the fixes for which the various archs needed to base their work. So in the end, this turned into a nice collaborative effort fixing up issues and porting to 5 new architectures -- arm64, powerpc64, powerpc32, s390x, and loongarch64 -- with everybody pitching in and commenting on each other's code. It was a fun development cycle. This contains: - Numerous fixups to the vDSO selftest infrastructure, getting it running successfully on more platforms, and fixing bugs in it. - Additions to the vDSO getrandom & chacha selftests. Basically every time manual review unearthed a bug in a revision of an arch patch, or an ambiguity, the tests were augmented. By the time the last arch was submitted for review, s390x, v1 of the series was essentially fine right out of the gate. - Fixes to the the generic C implementation of vDSO getrandom, to build and run successfully on all archs, decoupling it from assumptions we had (unintentionally) made on x86_64 that didn't carry through to the other architectures. - Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by Huacai Chen. - Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked by Will Deacon. - Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit varieties, from Christophe Leroy and acked by Michael Ellerman. - Port of vDSO getrandom to S390X from Heiko Carstens, the arch maintainer. While it'd be natural for there to be things to fix up over the course of the development cycle, these patches got a decent amount of review from a fairly diverse crew of folks on the mailing lists, and, for the most part, they've been cooking in linux-next, which has been helpful for ironing out build issues. In terms of architectures, I think that mostly takes care of the important 64-bit archs with hardware still being produced and running production loads in settings where vDSO getrandom is likely to help. Arguably there's still RISC-V left, and we'll see for 6.13 whether they find it useful and submit a port" * tag 'random-6.12-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (47 commits) selftests: vDSO: check cpu caps before running chacha test s390/vdso: Wire up getrandom() vdso implementation s390/vdso: Move vdso symbol handling to separate header file s390/vdso: Allow alternatives in vdso code s390/module: Provide find_section() helper s390/facility: Let test_facility() generate static branch if possible s390/alternatives: Remove ALT_FACILITY_EARLY s390/facility: Disable compile time optimization for decompressor code selftests: vDSO: fix vdso_config for s390 selftests: vDSO: fix ELF hash table entry size for s390x powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO64 powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO32 powerpc/vdso: Refactor CFLAGS for CVDSO build powerpc/vdso32: Add crtsavres mm: Define VM_DROPPABLE for powerpc/32 powerpc/vdso: Fix VDSO data access when running in a non-root time namespace selftests: vDSO: don't include generated headers for chacha test arm64: vDSO: Wire up getrandom() vDSO implementation arm64: alternative: make alternative_has_cap_likely() VDSO compatible selftests: vDSO: also test counter in vdso_test_chacha ... |

Performance events changes for v6.12:
- Implement per-PMU context rescheduling to significantly improve single-PMU performance, and related cleanups/fixes. (by Peter Zijlstra and Namhyung Kim) - Fix ancient bug resulting in a lot of events being dropped erroneously at higher sampling frequencies. (by Luo Gengkun) - uprobes enhancements: - Implement RCU-protected hot path optimizations for better performance: "For baseline vs SRCU, peak througput increased from 3.7 M/s (million uprobe triggerings per second) up to about 8 M/s. For uretprobes it's a bit more modest with bump from 2.4 M/s to 5 M/s. For SRCU vs RCU Tasks Trace, peak throughput for uprobes increases further from 8 M/s to 10.3 M/s (+28%!), and for uretprobes from 5.3 M/s to 5.8 M/s (+11%), as we have more work to do on uretprobes side. Even single-thread (no contention) performance is slightly better: 3.276 M/s to 3.396 M/s (+3.5%) for uprobes, and 2.055 M/s to 2.174 M/s (+5.8%) for uretprobes." (by Andrii Nakryiko et al) - Document mmap_lock, don't abuse get_user_pages_remote(). (by Oleg Nesterov) - Cleanups & fixes to prepare for future work: - Remove uprobe_register_refctr() - Simplify error handling for alloc_uprobe() - Make uprobe_register() return struct uprobe * - Fold __uprobe_unregister() into uprobe_unregister() - Shift put_uprobe() from delete_uprobe() to uprobe_unregister() - BPF: Fix use-after-free in bpf_uprobe_multi_link_attach() (by Oleg Nesterov) - New feature & ABI extension: allow events to use PERF_SAMPLE READ with inheritance, enabling sample based profiling of a group of counters over a hierarchy of processes or threads.

lkmm: Add documentation and mailing list
This pull request contains documentation updates from Andrea Parri and Akira Yokosawa. Also, there is now an lkmm@lists.linux.dev, and Boqun Feng's update adds this to the LKMM MAINTAINERS entry. Not included in this pull request are a couple of more commits from Puranjay Mohan adding more atomic operations to LKMM, but these await a herdtools7 release that includes tool-side support for this functionality.

sound updates for 6.12-rc1
A fairly big update at this time, both in core and driver sides. The core received rewrites in PCM buffer allocation handling and locking optimizations, PCM rate updates followed by lots of cleanups. In ASoC side, the legacy Intel drivers have been deprecated by AVS drivers which leaded to the significant amount of code reduction.

Updates for x86 memory management:
- Make LAM enablement safe vs. kernel threads using a process mm temporarily as switching back to the process would not update CR3 and therefore not enable LAM causing faults in user space when using tagged pointers. Cure it by synchronizing LAM enablement via IPIs to all CPUs which use the related mm. - Cure a LAM harmless inconsistency between CR3 and the state during context switch. It's both confusing and prone to lead to real bugs - Handle alt stack handling for threads which run with a non-zero protection key. The non-zero key prevents the kernel to access the alternate stack. Cure it by temporarily enabling all protection keys for the alternate stack setup/restore operations. - Provide a EFI config table identity mapping for kexec kernel to prevent kexec fails because the new kernel cannot access the config table array - Use GB pages only when a full GB is mapped in the identity map as otherwise the CPU can speculate into reserved areas after the end of memory which causes malfunction on UV systems. - Remove the noisy and pointless SRAT table dump during boot - Use is_ioremap_addr() for iounmap() address range checks instead of high_memory. is_ioremap_addr() is more precise. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmbpPpYTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoYddD/9HeH5/rpWS3JU4ZVC+huY28uJuwAFW ER48zniRbmuz8y+dZZ6K8uvqoWB+ro+yNjA9Jhm9nHUzhs7kE5O8+bmkUi6HXViW 6zS6PW95+u80dmSGy1Gna0SU3158OyBf2X61SySJABLLek7WwrR7jakkgrDBVtL5 ILKS/dUwIrUPoVlszCh9uE0Kj6gdFquooE06sif5EIibnhSgSXfr2EbGj0Qq/YYf FYfpggSSVpTXFSkZSB2VCEqK66jaGUfKzZ6v1DkSioChUCsky2OO6zD9pk0dMixO a/0XvRUo3OhiXZbj1tPUtxaEBgJdigpsxke7xQSVxSl+DNNuapiybpgAzFM5Xh+m yFcP66nIpJcHE10vjVR3jSUlTSb2zk+v9d1Ujj10G1h8RHLTfsTCRHgzs7P0/nkE NJleWstYVRV5rFpPLoY0ryQmjW/PzYokkaqWKI12Lhxg4ojijZso3pS8WfOsk1/B 081tOZERWeGnJEOOJwwYE1wt0Qq8th4S9b2/fz3vk2fsEHIf42s4fKQwy1CxKopb PyIrgnZyWx6ueX9QaIGIzGV1GsY4FKMgFJVOyVb0D0stMnr1ty2m3993eNs/nCXy +rHPMwFteLcwiWp/C3hq5IQd7uEvmRt/mYJ5hdvCj5wCIkXI3JtgsXfLSVs3Ln4f R6HvZehYmbJoNQ== =VZcR -----END PGP SIGNATURE----- Merge tag 'x86-mm-2024-09-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 memory management updates from Thomas Gleixner: - Make LAM enablement safe vs. kernel threads using a process mm temporarily as switching back to the process would not update CR3 and therefore not enable LAM causing faults in user space when using tagged pointers.

spi: Updates for v6.12
This is quite a quiet release for sPI. The one new core feature here is support for configuring the state of the MOSI pin when the bus is idle, there are some devices which are very fragile in this regard even when the chip select signal is not asserted. Otherwise we have some new driver support, a bunch of small fixes and some general cleanup work. - Support for configuring the state of the MOSI pin when the the bus is idle. - Add the Elgin JG0309-01 in spidev. - Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX, NXP i.MX8ULP, and Rockchip RK3576 controllers.

Those callbacks which haven't been converted were left as-is due to the general ugliness of the changes required to support the static call conversion; we can revisit those callbacks at a future date. - Add the Integrity Policy Enforcement (IPE) LSM This adds a new LSM, Integrity Policy Enforcement (IPE). There is plenty of documentation about IPE in this patches, so I'll refrain from going into too much detail here, but the basic motivation behind IPE is to provide a mechanism such that administrators can restrict execution to only those binaries which come from integrity protected storage, e.g. a dm-verity protected filesystem. You will notice that IPE requires additional LSM hooks in the initramfs, dm-verity, and fs-verity code, with the associated patches carrying ACK/review tags from the associated maintainers. We couldn't find an obvious maintainer for the initramfs code, but the IPE patchset has been widely posted over several years. Both Deven Bowers and Fan Wu have contributed to IPE's development over the past several years, with Fan Wu agreeing to serve as the IPE maintainer moving forward. Once IPE is accepted into your tree, I'll start working with Fan to ensure he has the necessary accounts, keys, etc. so that he can start submitting IPE pull requests to you directly during the next merge window. - Move the lifecycle management of the LSM blobs to the LSM framework Management of the LSM blobs (the LSM state buffers attached to various kernel structs, typically via a void pointer named "security" or similar) has been mixed, some blobs were allocated/managed by individual LSMs, others were managed by the LSM framework itself. Starting with this pull we move management of all the LSM blobs, minus the XFRM blob, into the framework itself, improving consistency across LSMs, and reducing the amount of duplicated code across LSMs. Due to some additional work required to migrate the XFRM blob, it has been left as a todo item for a later date; from a practical standpoint this omission should have little impact as only SELinux provides a XFRM LSM implementation. - Fix problems with the LSM's handling of F_SETOWN The LSM hook for the fcntl(F_SETOWN) operation had a couple of problems: it was racy with itself, and it was disconnected from the associated DAC related logic in such a way that the LSM state could be updated in cases where the DAC state would not. We fix both of these problems by moving the security_file_set_fowner() hook into the same section of code where the DAC attributes are updated. Not only does this resolve the DAC/LSM synchronization issue, but as that code block is protected by a lock, it also resolve the race condition. - Fix potential problems with the security_inode_free() LSM hook Due to use of RCU to protect inodes and the placement of the LSM hook associated with freeing the inode, there is a bit of a challenge when it comes to managing any LSM state associated with an inode. The VFS folks are not open to relocating the LSM hook so we have to get creative when it comes to releasing an inode's LSM state. Traditionally we have used a single LSM callback within the hook that is triggered when the inode is "marked for death", but not actually released due to RCU. Unfortunately, this causes problems for LSMs which want to take an action when the inode's associated LSM state is actually released; so we add an additional LSM callback, inode_free_security_rcu(), that is called when the inode's LSM state is released in the RCU free callback. - Refactor two LSM hooks to better fit the LSM return value patterns The vast majority of the LSM hooks follow the "return 0 on success, negative values on failure" pattern, however, there are a small handful that have unique return value behaviors which has caused confusion in the past and makes it difficult for the BPF verifier to properly vet BPF LSM programs. This includes patches to convert two of these"special" LSM hooks to the common 0/-ERRNO pattern. - Various cleanups and improvements A handful of patches to remove redundant code, better leverage the IS_ERR_OR_NULL() helper, add missing "static" markings, and do some minor style fixups. * tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (40 commits) security: Update file_set_fowner documentation fs: Fix file_set_fowner LSM hook inconsistencies lsm: Use IS_ERR_OR_NULL() helper function lsm: remove LSM_COUNT and LSM_CONFIG_COUNT ipe: Remove duplicated include in ipe.c lsm: replace indirect LSM hook calls with static calls lsm: count the LSMs enabled at compile time kernel: Add helper macros for loop unrolling init/main.c: Initialize early LSMs after arch code, static keys and calls.

selftests: vDSO: check cpu caps before running chacha test
Some archs -- arm64 and s390x -- implemented chacha using instructions that are available most places, but aren't always available. The kernel handles this just fine, but the selftest does not. Check the hwcaps before running, and skip the test if the cpu doesn't support it. As well, on s390x, always emit the fallback instructions of an alternative block, to ensure maximum compatibility.

Often userspace wants to know whether an O_CREATE request did actually create a file without using O_EXCL. The current logic is that to first attempts to open the file without O_CREAT | O_EXCL and if ENOENT is returned userspace tries again with both flags. If that succeeds all is well. If it now reports EEXIST it retries. That works fairly well but some corner cases make this more involved. If this operates on a dangling symlink the first openat() without O_CREAT | O_EXCL will return ENOENT but the second openat() with O_CREAT | O_EXCL will fail with EEXIST. The reason is that openat() without O_CREAT | O_EXCL follows the symlink while O_CREAT | O_EXCL doesn't for security reasons. So it's not something we can really change unless we add an explicit opt-in via O_FOLLOW which seems really ugly. All available workarounds are really nasty (fanotify, bpf lsm etc) so add a simple fcntl(). - Try an opportunistic lookup for O_CREAT. Today, when opening a file we'll typically do a fast lookup, but if O_CREAT is set, the kernel always takes the exclusive inode lock. This was likely done with the expectation that O_CREAT means that we always expect to do the create, but that's often not the case. Many programs set O_CREAT even in scenarios where the file already exists (see related F_CREATED_QUERY patch motivation above). The series contained in the pr rearranges the pathwalk-for-open code to also attempt a fast_lookup in certain O_CREAT cases. If a positive dentry is found, the inode_lock can be avoided altogether and it can stay in rcuwalk mode for the last step_into. - Expose the 64 bit mount id via name_to_handle_at() Now that we provide a unique 64-bit mount ID interface in statx(2), we can now provide a race-free way for name_to_handle_at(2) to provide a file handle and corresponding mount without needing to worry about racing with /proc/mountinfo parsing or having to open a file just to do statx(2). While this is not necessary if you are using AT_EMPTY_PATH and don't care about an extra statx(2) call, users that pass full paths into name_to_handle_at(2) need to know which mount the file handle comes from (to make sure they don't try to open_by_handle_at a file handle from a different filesystem) and switching to AT_EMPTY_PATH would require allocating a file for every name_to_handle_at(2) call - Add a per dentry expire timeout to autofs There are two fairly well known automounter map formats, the autofs format and the amd format (more or less System V and Berkley). Some time ago Linux autofs added an amd map format parser that implemented a fair amount of the amd functionality. This was done within the autofs infrastructure and some functionality wasn't implemented because it either didn't make sense or required extra kernel changes. The idea was to restrict changes to be within the existing autofs functionality as much as possible and leave changes with a wider scope to be considered later. One of these changes is implementing the amd options: 1) "unmount", expire this mount according to a timeout (same as the current autofs default). 2) "nounmount", don't expire this mount (same as setting the autofs timeout to 0 except only for this specific mount) . 3) "utimeout=<seconds>", expire this mount using the specified timeout (again same as setting the autofs timeout but only for this mount) To implement these options per-dentry expire timeouts need to be implemented for autofs indirect mounts. This is because all map keys (mounts) for autofs indirect mounts use an expire timeout stored in the autofs mount super block info. structure and all indirect mounts use the same expire timeout. Fixes: - Fix missing fput for FSCONFIG_SET_FD in autofs - Use param->file for FSCONFIG_SET_FD in coda - Delete the 'fs/netfs' proc subtreee when netfs module exits - Make sure that struct uid_gid_map fits into a single cacheline - Don't flush in-flight wb switches for superblocks without cgroup writeback - Correcting the idmapping mount example in the idmapping documentation - Fix a race between evice_inodes() and find_inode() and iput() - Refine the show_inode_state() macro definition in writeback code - Prevent dump_mapping() from accessing invalid dentry.d_name.name - Show actual source for debugfs in /proc/mounts - Annotate data-race of busy_poll_usecs in eventpoll - Don't WARN for racy path_noexec check in exec code - Handle OOM on mnt_warn_timestamp_expiry() - Fix some spelling in the iomap design documentation - Fix typo in procfs comment - Fix typo in fs/namespace.c comment Cleanups: - Add the VFS git tree to the MAINTAINERS file - Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode bit in struct file bringing us to 5 free f_mode bits - Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify the wait mechanism - Remove the unused path_put_init() helper - Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi specific - Replace the unsigned long i_state member with a u32 i_state member in struct inode freeing up 4 bytes in struct inode.

Apart from the above, there is a usual collection of assorted fixes and code cleanups in many places and there are tooling updates. Specifics: - Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef) - Add support for Granite Rapids and Sierra Forest in OOB mode to the intel_pstate cpufreq driver (Srinivas Pandruvada) - Add basic support for CPU capacity scaling on x86 and make the intel_pstate driver set asymmetric CPU capacity on hybrid systems without SMT (Rafael Wysocki) - Add missing MODULE_DESCRIPTION() macros to the powerpc cpufreq driver (Jeff Johnson) - Several OF related cleanups in cpufreq drivers (Rob Herring) - Enable COMPILE_TEST for ARM drivers (Rob Herrring) - Introduce quirks for syscon failures and use socinfo to get revision for TI cpufreq driver (Dhruva Gole, Nishanth Menon) - Minor cleanups in amd-pstate driver (Anastasia Belova, Dhananjay Ugwekar) - Minor cleanups for loongson, cpufreq-dt and powernv cpufreq drivers (Danila Tikhonov, Huacai Chen, and Liu Jing) - Make amd-pstate validate return of any attempt to update EPP limits, which fixes the masking hardware problems (Mario Limonciello) - Move the calculation of the AMD boost numerator outside of amd-pstate, correcting acpi-cpufreq on systems with preferred cores (Mario Limonciello) - Harden preferred core detection in amd-pstate to avoid potential false positives (Mario Limonciello) - Add extra unit test coverage for mode state machine (Mario Limonciello) - Fix an "Uninitialized variables" issue in amd-pstste (Qianqiang Liu) - Add Granite Rapids Xeon support to intel_idle (Artem Bityutskiy) - Disable promotion to C1E on Jasper Lake and Elkhart Lake in intel_idle (Kai-Heng Feng) - Use scoped device node handling to fix missing of_node_put() and simplify walking OF children in the riscv-sbi cpuidle driver (Krzysztof Kozlowski) - Remove dead code from cpuidle_enter_state() (Dhruva Gole) - Change an error pointer to NULL to fix error handling in the intel_rapl power capping driver (Dan Carpenter) - Fix off by one in get_rpi() in the intel_rapl power capping driver (Dan Carpenter) - Add support for ArrowLake-U to the intel_rapl power capping driver (Sumeet Pawnikar) - Fix the energy-pkg event for AMD CPUs in the intel_rapl power capping driver (Dhananjay Ugwekar) - Add support for AMD family 1Ah processors to the intel_rapl power capping driver (Dhananjay Ugwekar) - Remove unused stub for saveable_highmem_page() and remove deprecated macros from power management documentation (Andy Shevchenko) - Use ysfs_emit() and sysfs_emit_at() in "show" functions in the PM sysfs interface (Xueqin Luo) - Update the maintainers information for the operating-points-v2-ti-cpu DT binding (Dhruva Gole) - Drop unnecessary of_match_ptr() from ti-opp-supply (Rob Herring) - Add missing MODULE_DESCRIPTION() macros to devfreq governors (Jeff Johnson) - Use devm_clk_get_enabled() in the exynos-bus devfreq driver (Anand Moon) - Use of_property_present() instead of of_get_property() in the imx-bus devfreq driver (Rob Herring) - Update directory handling and installation process in the pm-graph Makefile and add .gitignore to ignore sleepgraph.py artifacts to pm-graph (Amit Vadhavana, Yo-Jung Lin) - Make cpupower display residency value in idle-info (Aboorva Devarajan) - Add missing powercap_set_enabled() stub function to cpupower (John B.

ASoC: Updates for v6.12
This is a very large set of changes, almost all in drivers rather than the core. Even with the addition of several quite large drivers the overall diffstat is negative thanks to the removal of some old Intel board support which has been obsoleted by the AVS driver, helped a bit by some factoring out into helpers (especially around the Soundwire machine drivers for x86). Highlights include: - More simplifications and cleanups throughout the subsystem from Morimoto-san. - Extensive cleanups and refactoring of the Soundwire drivers to make better use of helpers. - Removal of Intel machine support obsoleted by the AVS driver. - Lots of DT schema conversions. - Machine support for many AMD and Intel x86 platforms. - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320 SoundWire and rev C, and Texas Instruments TAS2563 -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmbko34ACgkQJNaLcl1U h9CQiwf9HseC6VkNQ0ISVZ2UsSf8K/HsHsdBGl7/CRr0SEvS3pszYMkKPbhRggsF aQ4nfitXeN7Vo6S0tNXx63wzjpMPkjrHdV0XY+WJxfuCaeb3DHFEJ4uvlgv53aoh M+wz1aldvKWjDPwhkzcJEaneQ36U7OlUSBsbFHR82dBDguEm+h29tAxTuLlwL5Zb M8NuSfbh0cfY9Kk1cPGsqaHD8wjUeg6/Q5qnbDg2kAm0aF1fAxfyFKRX6Z5s9ekd LeU3EIdRbI8UlHv7Afl0UKDYtYqL1ubwmjDb45HnsE4FmNEmDEbf8c1adRumZAjm Js9yzswiaaHAvotCaEstFC6HYUL+oQ== =jugn -----END PGP SIGNATURE----- Merge tag 'asoc-v6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v6.12 This is a very large set of changes, almost all in drivers rather than the core.

tools/memory-model: Document herd7 (abstract) representation
The Linux-kernel memory model (LKMM) source code and the herd7 tool are closely linked in that the latter is responsible for (pre)processing each C-like macro of a litmus test, and for providing the LKMM with a set of events, or "representation", corresponding to the given macro. This commit therefore provides herd-representation.txt to document the representations of the concurrency macros, following their "classification" in Documentation/atomic_t.txt.

s390/vdso: Wire up getrandom() vdso implementation
Provide the s390 specific vdso getrandom() architecture backend. _vdso_rng_data required data is placed within the _vdso_data vvar page, by using a hardcoded offset larger than vdso_data. As required the chacha20 implementation does not write to the stack. The implementation follows more or less the arm64 implementations and makes use of vector instructions. It has a fallback to the getrandom() system call for machines where the vector facility is not installed. The check if the vector facility is installed, as well as an optimization for machines with the vector-enhancements facility 2, is implemented with alternatives, avoiding runtime checks. Note that __kernel_getrandom() is implemented without the vdso user wrapper which would setup a stack frame for odd cases (aka very old glibc variants) where the caller has not done that. All callers of __kernel_getrandom() are required to setup a stack frame, like the C ABI requires it. The vdso testcases vdso_test_getrandom and vdso_test_chacha pass.

selftests: vDSO: fix vdso_config for s390
Running vdso_test_correctness on s390x (aka s390 64 bit) emits a warning:
Warning: failed to find clock_gettime64 in vDSO
This is caused by the "#elif defined (__s390__)" check in vdso_config.h
which the defines VDSO_32BIT.
If __s390x__ is defined also __s390__ is defined. Therefore the correct
check must make sure that only __s390__ is defined.
Therefore add the missing !defined(__s390x__). Also use common
__s390x__ define instead of __s390X__.

powerpc/vdso: Wire up getrandom() vDSO implementation on VDSO32
To be consistent with other VDSO functions, the function is called __kernel_getrandom() __arch_chacha20_blocks_nostack() fonction is implemented basically with 32 bits operations. It performs 4 QUARTERROUND operations in parallele. There are enough registers to avoid using the stack: On input: r3: output bytes r4: 32-byte key input r5: 8-byte counter input/output r6: number of 64-byte blocks to write to output During operation: stack: pointer to counter (r5) and non-volatile registers (r14-131) r0: counter of blocks (initialised with r6) r4: Value '4' after key has been read, used for indexing r5-r12: key r14-r15: block counter r16-r31: chacha state At the end: r0, r6-r12: Zeroised r5, r14-r31: Restored Performance on powerpc 885 (using kernel selftest): ~# ./vdso_test_getrandom bench-single vdso: 25000000 times in 62.938002291 seconds libc: 25000000 times in 535.581916866 seconds syscall: 25000000 times in 531.525042806 seconds Performance on powerpc 8321 (using kernel selftest): ~# ./vdso_test_getrandom bench-single vdso: 25000000 times in 16.899318858 seconds libc: 25000000 times in 131.050596522 seconds syscall: 25000000 times in 129.794790389 seconds This first patch adds support for VDSO32. As selftests cannot easily be generated only for VDSO32, and because the following patch brings support for VDSO64 anyway, this patch opts out all code in __arch_chacha20_blocks_nostack() so that vdso_test_chacha will not fail to compile and will not crash on PPC64/PPC64LE, allthough the selftest itself will fail.

selftests: vDSO: don't include generated headers for chacha test
It's not correct to use $(top_srcdir) for generated header files, for builds that are done out of tree via O=, and $(objtree) isn't valid in the selftests context. Instead, just obviate the need for these generated header files by defining empty stubs in tools/include, which is the same thing that's done for rwlock.h.

arm64: vDSO: Wire up getrandom() vDSO implementation
Hook up the generic vDSO implementation to the aarch64 vDSO data page. The _vdso_rng_data required data is placed within the _vdso_data vvar page, by using a offset larger than the vdso_data. The vDSO function requires a ChaCha20 implementation that does not write to the stack, and that can do an entire ChaCha20 permutation. The one provided uses NEON on the permute operation, with a fallback to the syscall for chips that do not support AdvSIMD. This also passes the vdso_test_chacha test along with vdso_test_getrandom. The vdso_test_getrandom bench-single result on Neoverse-N1 shows: vdso: 25000000 times in 0.783884250 seconds libc: 25000000 times in 8.780275399 seconds syscall: 25000000 times in 8.786581518 seconds A small fixup to arch/arm64/include/asm/mman.h was required to avoid pulling kernel code into the vDSO, similar to what's already done in arch/arm64/include/asm/rwonce.h.

selftests: vDSO: also test counter in vdso_test_chacha
The chacha vDSO selftest doesn't check the way the counter is handled by __arch_chacha20_blocks_nostack(). It indirectly checks that the counter is writen on exit and read back on new entry, but it doesn't check that the format is correct. When implementing this function on powerpc, I missed a case where the counter was writen and read in wrong byte order. Also, the counter uses two words, but the tests with a zero counter and uses a small amount of blocks, so at the end the upper part of the counter is always 0, so it is not checked. Add a verification of counter's content in addition to the verification of the output. Also add two tests where the counter crosses the u32 upper limit. The first test verifies that the function properly writes back the upper word, the second test verifies that the function properly reads back the upper word.

selftests: vDSO: fix cross build for getrandom and chacha tests
Unlike the check for the standalone x86 test, the check for building the vDSO getrandom and chacaha tests looks at the architecture for the host rather than the architecture for the target when deciding if they should be built. Since the chacha test includes some assembler code this means that cross building with x86 as either the target or host is broken. There's also some additional complications, where ARCH can legitimately be either x86_64 or x86, but the source code we need to compile lives in a directory path containing arch/x86. The standard SRCARCH variable handles that. And actually, all these variables and proper substitutions are already described in tools/scripts/Makefile.arch, so just include that to handle it. Similarly, ARCH=x86 can actually describe ARCH=x86_64, just with CONFIG_64BIT, so we can't rely on ARCH for selecting non-32-bit tests. For that, check against $(ARCH)$(CONFIG_X86_32). This won't help for people manually running this inside the vDSO selftest directory (which isn't really supported anyway and has problems on various archs), but it should work for builds of the kselftests, where the CONFIG_* variables are defined. On x86_64 machines, $(ARCH)$(CONFIG_X86_32) will evaluate to x86. On arm64 machines, it will evaluate to arm64. On 32-bit x86 machines, it will evaluate to x86y, which won't match the filter list.

selftests: vDSO: open code basic chacha instead of linking to libsodium
Linking to libsodium makes building this test annoying in cross compilation environments and is just way too much. Since this is just a basic correctness test, simply open code a simple, unoptimized, dumb chacha, rather than linking to libsodium. This also fixes a correctness issue on big endian systems. The kernel's random.c doesn't bother doing a le32_to_cpu operation on the random bytes that are passed as the key, and consequently neither does vgetrandom-chacha.S. However, libsodium's chacha _does_ do this, since it takes the key as an array of bytes. This meant that the test was broken on big endian systems, which this commit rectifies.

random: vDSO: move prototype of arch chacha function to vdso/getrandom.h
Having the prototype for __arch_chacha20_blocks_nostack in arch/x86/include/asm/vdso/getrandom.h meant that the prototype and large doc comment were cloned by every architecture, which has been causing unnecessary churn. Instead move it into include/vdso/getrandom.h, where it can be shared by all archs implementing it. As a side bonus, this then lets us use that prototype in the vdso_test_chacha self test, to ensure that it matches the source, and indeed doing so turned up some inconsistencies, which are rectified here.

selftests: vDSO: ensure vgetrandom works in a time namespace
After verifying that vDSO getrandom does work, which ensures that the RNG is initialized, test to see if it also works inside of a time namespace. This is important to test, because the vvar pages get swizzled around there. If the arch code isn't careful, the RNG will appear uninitialized inside of a time namespace. Because broken code makes the RNG appear uninitialized, test that everything works by issuing a call to vgetrandom from a fork in a time namespace, and use ptrace to ensure that the actual syscall getrandom doesn't get called. If it doesn't get called, then the test succeeds. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |
