more s390 updates for 6.14 merge window
- The rework that uncoupled physical and virtual address spaces inadvertently prevented KASAN shadow mappings from using large pages. Restore large page mappings for KASAN shadows - Add decompressor routine physmem_alloc() that may fail, unlike physmem_alloc_or_die(). This allows callers to implement fallback paths - Allow falling back from large pages to smaller pages (1MB or 4KB) if the allocation of 2GB pages in the decompressor can not be fulfilled - Add to the decompressor boot print support of "%%" format string, width and padding hadnling, length modifiers and decimal conversion specifiers - Add to the decompressor message severity levels similar to kernel ones. Support command-line options that control console output verbosity - Replaces boot_printk() calls with appropriate loglevel- specific helpers such as boot_emerg(), boot_warn(), and boot_debug(). - Collect all boot messages into a ring buffer independent of the current log level. This is particularly useful for early crash analysis - If 'earlyprintk' command line parameter is not specified, store decompressor boot messages in a ring buffer to be printed later by the kernel, once the console driver is registered - Add 'bootdebug' command line parameter to enable printing of decompressor debug messages when needed. That parameters allows message supressing and filtering - Dump boot messages on a decompressor crash, but only if 'bootdebug' command line parameter is enabled - When CONFIG_PRINTK_TIME is enabled, add timestamps to boot messages in the same format as regular printk() - Dump physical memory tracking information on boot: online ranges, reserved areas and vmem allocations - Dump virtual memory layout and randomization details - Improve decompression error reporting and dump the message ring buffer in case the boot failed and system halted - Add an exception handler which handles exceptions when FPU control register is attempted to be set to an invalid value. Remove '.fixup' section as result of this change - Use 'A', 'O', and 'R' inline assembly format flags, which allows recent Clang compilers to generate better FPU code - Rework uaccess code so it reads better and generates more efficient code - Cleanup futex inline assembly code - Disable KMSAN instrumention for futex inline assemblies, which contain dereferenced user pointers. Otherwise, shadows for the user pointers would be accessed - PFs which are not initially configured but in standby create only a single-function PCI domain. If they are configured later on, sibling PFs and their child VFs will not be added to their PCI domain breaking SR-IOV expectations. Fix that by allowing initially configured but in standby PFs create multi-function PCI domains - Add '-std=gnu11' to decompressor and purgatory CFLAGS to avoid compile errors caused by kernel's own definitions of 'bool', 'false', and 'true' conflicting with the C23 reserved keywords - Fix sclp subsystem failure when a sclp console is not present - Fix misuse of non-NULL terminated strings in vmlogrdr driver - Various other small improvements, cleanups and fixes -----BEGIN PGP SIGNATURE----- iI0EABYKADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZ5t0jhccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8A4wAP91BcHtV4OTmoMsG4JTwiy9wTzI zro9IrBSCLPLED7kfQEAzjEspd5gWMFDnIM/KxXmCNHA/nBTXVh/1F+b1F0z+Q8= =JfEG -----END PGP SIGNATURE----- Merge tag 's390-6.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Alexander Gordeev: - The rework that uncoupled physical and virtual address spaces inadvertently prevented KASAN shadow mappings from using large pages.

Provide stable parent and name to ->d_revalidate() instances
Most of the filesystem methods where we care about dentry name
and parent have their stability guaranteed by the callers;
->d_revalidate() is the major exception.
It's easy enough for callers to supply stable values for
expected name and expected parent of the dentry being
validated. That kills quite a bit of boilerplate in
->d_revalidate() instances, along with a bunch of races
where they used to access ->d_name without sufficient
precautions.

bcachefs fixes for 6.14-rc1
- second half of a fix for a bug that'd been causing oopses on
filesystems using snapshots with memory pressure (key cache fills for
snaphots btrees are tricky)
- build fix for strange compiler configurations that double stack frame
size
- "journal stuck timeout" now takes into account device latency: this
fixes some spurious warnings, and the main remaining source of SRCU
lock hold time warnings (I'm no longer seeing this in my CI, so any
users still seeing this should definitely ping me)
- fix for slow/hanging unmounts (" Improve journal pin flushing")
- some more tracepoint fixes/improvements, to chase down the "rebalance
isn't making progress" issues

lib/crc: simplify the kconfig options for CRC implementations
Make the following simplifications to the kconfig options for choosing CRC implementations for CRC32 and CRC_T10DIF: 1. Make the option to disable the arch-optimized code be visible only when CONFIG_EXPERT=y. 2. Make a single option control the inclusion of the arch-optimized code for all enabled CRC variants. 3. Make CRC32_SARWATE (a.k.a. slice-by-1 or byte-by-byte) be the only generic CRC32 implementation. The result is there is now just one option, CRC_OPTIMIZATIONS, which is default y and can be disabled only when CONFIG_EXPERT=y. Rationale: 1. Enabling the arch-optimized code is nearly always the right choice. However, people trying to build the tiniest kernel possible would find some use in disabling it. Anything we add to CRC32 is de facto unconditional, given that CRC32 gets selected by something in nearly all kernels. And unfortunately enabling the arch CRC code does not eliminate the need to build the generic CRC code into the kernel too, due to CPU feature dependencies. The size of the arch CRC code will also increase slightly over time as more CRC variants get added and more implementations targeting different instruction set extensions get added. Thus, it seems worthwhile to still provide an option to disable it, but it should be considered an expert-level tweak. 2. Considering the use case described in (1), there doesn't seem to be sufficient value in making the arch-optimized CRC code be independently configurable for different CRC variants. Note also that multiple variants were already grouped together, e.g. CONFIG_CRC32 actually enables three different variants of CRC32. 3. The bit-by-bit implementation is uselessly slow, whereas slice-by-n for n=4 and n=8 use tables that are inconveniently large: 4096 bytes and 8192 bytes respectively, compared to 1024 bytes for n=1. Higher n gives higher instruction-level parallelism, so higher n easily wins on traditional microbenchmarks on most CPUs. However, the larger tables, which are accessed randomly, can be harmful in real-world situations where the dcache may be cold or useful data may need be evicted from the dcache. Meanwhile, today most architectures have much faster CRC32 implementations using dedicated CRC32 instructions or carryless multiplication instructions anyway, which make the generic code obsolete in most cases especially on long messages. Another reason for going with n=1 is that this is already what is used by all the other CRC variants in the kernel. CRC32 was unique in having support for larger tables. But as per the above this can be considered an outdated optimization. The standardization on slice-by-1 a.k.a. CRC32_SARWATE makes much of the code in lib/crc32.c unused. A later patch will clean that up. Link: https://lore.kernel.org/r/20250123212904.118683-2-ebiggers@kernel.org Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Martin K.

VFIO updates for v6.14-rc1
- Extend vfio-pci 8-byte read/write support to include archs defining
CONFIG_GENERIC_IOMAP, such as x86, and remove now extraneous #ifdefs
around 64-bit accessors. (Ramesh Thomas)
- Update vfio-pci shadow ROM handling and allow cached ROM from setup
data to be exposed as a functional ROM BAR region when available.
(Yunxiang Li)
- Update nvgrace-gpu vfio-pci variant driver for new Grace Blackwell
hardware, conditionalizing the uncached BAR workaround for previous
generation hardware based on the presence of a flag in a new DVSEC
capability, and include a delay during probe for link training to
complete, a new requirement for GB devices. (Ankit Agrawal)

x86/sev: Disable jump tables in SEV startup code
When retpolines and IBT are both disabled, the compiler is free to use
jump tables to optimize switch instructions. However, these are emitted
by Clang as absolute references into .rodata:
jmp *-0x7dfffe90(,%r9,8)
R_X86_64_32S .rodata+0x170
Given that this code will execute before that address in .rodata has even
been mapped, it is guaranteed to crash a SEV-SNP guest in a way that is
difficult to diagnose.
So disable jump tables when building this code. It would be better if we
could attach this annotation to the __head macro but this appears to be
impossible.

Driver core and debugfs updates
Here is the big set of driver core and debugfs updates for 6.14-rc1.
It's coming late in the merge cycle as there are a number of merge
conflicts with your tree now, and I wanted to make sure they were
working properly. To resolve them, look in linux-next, and I will send
the "fixup" patch as a response to the pull request.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at least
one user that does have a regression with these, but Al is working on
tracking down the fix for it. In my use (and everyone else's linux-next
use), it does not seem like a big issue at the moment.
Here's a short list of the things in here:
- driver core bindings for PCI, platform, OF, and some i/o functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing things
in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon".

KVM/arm64 updates for 6.14
* New features:
- Support for non-protected guest in protected mode, achieving near
feature parity with the non-protected mode
- Support for the EL2 timers as part of the ongoing NV support
- Allow control of hardware tracing for nVHE/hVHE
* Improvements, fixes and cleanups:
- Massive cleanup of the debug infrastructure, making it a bit less
awkward and definitely easier to maintain. This should pave the
way for further optimisations
- Complete rewrite of pKVM's fixed-feature infrastructure, aligning
it with the rest of KVM and making the code easier to follow
- Large simplification of pKVM's memory protection infrastructure
- Better handling of RES0/RES1 fields for memory-backed system
registers
- Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer
from a pretty nasty timer bug
- Small collection of cleanups and low-impact fixes

s390/sclp: Initialize sclp subsystem via arch_cpu_finalize_init()
With the switch to GENERIC_CPU_DEVICES an early call to the sclp subsystem
was added to smp_prepare_cpus(). This will usually succeed since the sclp
subsystem is implicitly initialized early enough if an sclp based console
is present.
If no such console is present the initialization happens with an
arch_initcall(); in such cases calls to the sclp subsystem will fail.
For CPU detection this means that the fallback sigp loop will be used
permanently to detect CPUs instead of the preferred READ_CPU_INFO sclp
request.
Fix this by adding an explicit early sclp_init() call via
arch_cpu_finalize_init().

s390/tools: Use array instead of string initializer
The in-kernel disassembler intentionally uses nun-null terminated
strings in order to keep the arrays which contain mnemonics as small
as possible. GCC 15 however warns about this:
./arch/s390/include/generated/asm/dis-defs.h:1662:71: error: initializer-string
for array of ‘char’ is too long [-Werror=unterminated-string-initialization]
1662 | [1261] = { .opfrag = 0xea, .format = INSTR_SS_L0RDRD, .name = "unpka" }, \
Get rid of this warning by using array initializers.

treewide: const qualify ctl_tables where applicable
Add the const qualifier to all the ctl_tables in the tree except for
watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,
loadpin_sysctl_table and the ones calling register_net_sysctl (./net,
drivers/inifiniband dirs). These are special cases as they use a
registration function with a non-const qualified ctl_table argument or
modify the arrays before passing them on to the registration function.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit

s390: Add '-std=gnu11' to decompressor and purgatory CFLAGS
GCC changed the default C standard dialect from gnu17 to gnu23,
which should not have impacted the kernel because it explicitly requests
the gnu11 standard in the main Makefile. However, there are certain
places in the s390 code that use their own CFLAGS without a '-std='
value, which break with this dialect change because of the kernel's own
definitions of bool, false, and true conflicting with the C23 reserved
keywords.
include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant
11 | false = 0,
| ^~~~~
include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards

| ^~~~
include/linux/types.h:35:33: note: 'bool' is a keyword with '-std=c23' onwards
Add '-std=gnu11' to the decompressor and purgatory CFLAGS to eliminate
these errors and make the C standard version of these areas match the
rest of the kernel.

NFSD 6.14 Release Notes
Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11. An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower. Neil Brown contributed dynamic NFSv4.1 session slot table resizing. This facility enables NFSD to increase or decrease the number of slots per NFS session depending on server memory availability. More session slots means greater parallelism. Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND encoding screws up when crossing a page boundary in the encoding buffer. This is a zero-day bug, but hitting it is rare and depends on the NFS client implementation. The Linux NFS client does not happen to trigger this issue. A variety of bug fixes and other incremental improvements fill out the list of commits in this release. Great thanks to all contributors, reviewers, testers, and bug reporters who participated during this development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmeVPBUACgkQM2qzM29m f5dClxAAmW4O2bOJaR8neJ54fzeFYXtFYEXRF/XbIh2KdnCy2LoywT9ux8ndzE0k 1tsjtv0g4y84IcYfrxXPRTuhh2GO2pHw5L1kGVRezJg2ODSFbpdzGtcVK7SIrs2S eijTViqdi9xRgfj1jPqRrvxC99RL3/fmCztqorAPLDFsqYAd/6ZRxZ7+IcZ2h4+J cJ0Z6Wx6eh10roacZPXweH13XJ7xWO/ublYZvQFQpK2BAKyO98aXGgLDraNt8k60 X3DZLSKkGB/eBlNeAlTtcrXec/ot6XGJPKr3b/7zhwfMi8B13RGdSmCR8SxMdRQM vCQO4G2YadU4YFS6FFIw9Wc1XDYUuYh2YgcveafjzjXbgi7NnY7rYOxtnTgBi0Xv XGjtGqpvD676gPm+8b3DcwqmWI3c/WUdtQIZ1uYRCFZdFqkVP91bySPT2aHtx2GO 4j3uEyTlypC00kyvu1oL3+tVUG/EFlJCpYvIbOwqDG2m7KWPStzpfJTD5Q9cdlEl fdgs6l82EVqe1YyjLTqajDuOcRrLYK2hlR/5STc03hQV+GpKSo5UypRejzE9WtRV zT/tyelqhj4+0EZJz4ay/8q9s2Jp+5JGVxoVvjujSuH7+Ulb3T+IDkldtMamO8Fm www2y0/fLfU2xIapMJdCoJ+ZKgel2i8RZMPIc0cIfO5ITXm+dOs= =hwXx -----END PGP SIGNATURE----- Merge tag 'nfsd-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11.

Char/Misc/IIO driver updates for 6.14-rc1
Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

USB / Thunderbolt driver updates for 6.14-rc1
Here is the USB and Thunderbolt driver updates for 6.14-rc1. Nothing
huge in here, just lots of new hardware support and updates for existing
drivers. Changes here are:
- big gadget f_tcm driver update
- other gadget driver updates and fixes
- thunderbolt driver updates for new hardware and capabilities and
lots more debugging functionality to handle it when things aren't
working well.
- xhci driver updates
- new USB-serial device updates
- typec driver updates, including a chrome platform driver (acked by
the subsystem maintainers)
- other small driver updates
All of these have been in linux-next for a while with no reported

9p: fix ->rename_sem exclusion
9p wants to be able to build a path from given dentry to fs root and keep it valid over a blocking operation. ->s_vfs_rename_mutex would be a natural candidate, but there are places where we need that and where we have no way to tell if ->s_vfs_rename_mutex is already held deeper in callchain. Moreover, it's only held for cross-directory renames; name changes within the same directory happen without it. Solution: * have d_move() done in ->rename() rather than in its caller * maintain a 9p-private rwsem (per-filesystem) * hold it exclusive over the relevant part of ->rename() * hold it shared over the places where we want the path. That almost works. FS_RENAME_DOES_D_MOVE is enough to put all d_move() and d_exchange() calls under filesystem's control. However, there's also __d_unalias(), which isn't covered by any of that. If ->lookup() hits a directory inode with preexisting dentry elsewhere (due to e.g. rename done on server behind our back), d_splice_alias() called by ->lookup() will move/rename that alias. Add a couple of optional methods, so that __d_unalias() would do if alias->d_op->d_unalias_trylock != NULL if (!alias->d_op->d_unalias_trylock(alias)) fail (resulting in -ESTALE from lookup) __d_move(...) if alias->d_op->d_unalias_unlock != NULL alias->d_unalias_unlock(alias) where it currently does __d_move(). 9p instances do down_write_trylock() and up_write() of ->rename_mutex.

nfs: fix ->d_revalidate() UAF on ->d_name accesses
Pass the stable name all the way down to ->rpc_ops->lookup() instances. Note that passing &dentry->d_name is safe in e.g. nfs_lookup() - it *is* stable there, as it is in ->create() et.al. dget_parent() in nfs_instantiate() should be redundant - it'd better be stable there; if it's not, we have more trouble, since ->d_name would also be unsafe in such case. nfs_submount() and nfs4_submount() may or may not require fixes - if they ever get moved on server with fhandle preserved, we are in trouble there... UAF window is fairly narrow here and exfiltration requires the ability to watch the traffic. Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |
