asm-generic updates for v6.7
The ia64 architecture gets its well-earned retirement as planned, now that there is one last (mostly) working release that will be maintained as an LTS kernel. The architecture specific system call tables are updated for the added map_shadow_stack() syscall and to remove references to the long-gone sys_lookup_dcookie() syscall. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmVC40IACgkQYKtH/8kJ Uidhmw/9EX+aWSXGoObJ3fngaNSMw+PmrEuP8qEKBHxfKHcCdX3hc451Oh4GlhaQ tru91pPwgNvN2/rfoKusxT+V4PemGIzfNni/04rp+P0kvmdw5otQ2yNhsQNsfVmq XGWvkxF4P2GO6bkjjfR/1dDq7GtlyXtwwPDKeLbYb6TnJOZjtx+EAN27kkfSn1Ms R4Sa3zJ+DfHUmHL5S9g+7UD/CZ5GfKNmIskI4Mz5GsfoUz/0iiU+Bge/9sdcdSJQ kmbLy5YnVzfooLZ3TQmBFsO3iAMWb0s/mDdtyhqhTVmTUshLolkPYyKnPFvdupyv shXcpEST2XJNeaDRnL2K4zSCdxdbnCZHDpjfl9wfioBg7I8NfhXKpf1jYZHH1de4 LXq8ndEFEOVQw/zSpYWfQq1sux8Jiqr+UK/ukbVeFWiGGIUs91gEWtPAf8T0AZo9 ujkJvaWGl98O1g5wmBu0/dAR6QcFJMDfVwbmlIFpU8O+MEaz6X8mM+O5/T0IyTcD eMbAUjj4uYcU7ihKzHEv/0SS9Of38kzff67CLN5k8wOP/9NlaGZ78o1bVle9b52A BdhrsAefFiWHp1jT6Y9Rg4HOO/TguQ9e6EWSKOYFulsiLH9LEFaB9RwZLeLytV0W vlAgY9rUW77g1OJcb7DoNv33nRFuxsKqsnz3DEIXtgozo9CzbYI= =H1vH -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull ia64 removal and asm-generic updates from Arnd Bergmann: - The ia64 architecture gets its well-earned retirement as planned, now that there is one last (mostly) working release that will be maintained as an LTS kernel. - The architecture specific system call tables are updated for the added map_shadow_stack() syscall and to remove references to the long-gone sys_lookup_dcookie() syscall. * tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: hexagon: Remove unusable symbols from the ptrace.h uapi asm-generic: Fix spelling of architecture arch: Reserve map_shadow_stack() syscall number for all architectures syscalls: Cleanup references to sys_lookup_dcookie() Documentation: Drop or replace remaining mentions of IA64 lib/raid6: Drop IA64 support Documentation: Drop IA64 from feature descriptions kernel: Drop IA64 support from sig_fault handlers arch: Remove Itanium (IA-64) architecture |

bcachefs: Enumerate fsck errors
This patch adds a superblock error counter for every distinct fsck error; this means that when analyzing filesystems out in the wild we'll be able to see what sorts of inconsistencies are being found and repair, and hence what bugs to look for. Errors validating bkeys are not yet considered distinct fsck errors, but this patch adds a new helper, bkey_fsck_err(), in order to add distinct error types for them as well.

bcachefs: Fix a kasan splat in bch2_dev_add()
This fixes a use after free - mi is dangling after the resize call. Additionally, resizing the device's member info section was useless - we were attempting to preallocate the space required before adding it to the filesystem superblock, but there's other sections that we should have been preallocating as well for that to work.

bcachefs: rebalance_work
This adds a new btree, rebalance_work, to eliminate scanning required for finding extents that need work done on them in the background - i.e. for the background_target and background_compression options. rebalance_work is a bitset btree, where a KEY_TYPE_set corresponds to an extent in the extents or reflink btree at the same pos. A new extent field is added, bch_extent_rebalance, which indicates that this extent has work that needs to be done in the background - and which options to use. This allows per-inode options to be propagated to indirect extents - at least in some circumstances. In this patch, changing IO options on a file will not propagate the new options to indirect extents pointed to by that file. Updating (setting/clearing) the rebalance_work btree is done by the extent trigger, which looks at the bch_extent_rebalance field. Scanning is still requrired after changing IO path options - either just for a given inode, or for the whole filesystem. We indicate that scanning is required by adding a KEY_TYPE_cookie key to the rebalance_work btree: the cookie counter is so that we can detect that scanning is still required when an option has been flipped mid-way through an existing scan. Future possible work: - Propagate options to indirect extents when being changed - Add other IO path options - nr_replicas, ec, to rebalance_work so they can be applied in the background when they change - Add a counter, for bcachefs fs usage output, showing the pending amount of rebalance work: we'll probably want to do this after the disk space accounting rewrite (moving it to a new btree) Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> |

SoC driver updates for 6.7
The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware drivers.
- Arm FF-A firmware support gains support for v1.1 specification features,
in particular notification and memory transaction descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper.

SoC DT updates for v6.7
There are a couple new SoCs that are supported for the first time:
- AMD Pensando Elba is a data processing unit based on Cortex-A72
CPU cores
- Sophgo makes RISC-V based chips, and we now support the CV1800B
chip used in the milkv-duo board and the massive sg2042 chip in the
milkv-pioneer, a 64-core developer workstation.
- Qualcomm Snapdragon 720G (sm7125) is a close relative of
Snapdragon 7c and gets added with some Xiaomi phones
- Renesas gains support for the R8A779F4 (R-Car S4-8) automotive
SoC and the RZ/G3S (R9A08G045) embedded SoC.
There are also a bunch of newly supported machines that use
already supported chips. On the 32-bit side, we have:
- USRobotics USR8200 is a NAS/Firewall/router based on the ancient
Intel IXP4xx platform
- A couple of machines based on the NXP i.MX5 and i.MX6 platforms
- One machine each for Allwinner V3s, Aspeed AST2600, Microchip
sama5d29 and ST STM32mp157
The other ones all use arm64 cores on chips from allwinner,
amlogic, freescale, mediatek, qualcomm and rockchip.

Pull SoC DT updates from Arnd Bergmann:
"There are a couple new SoCs that are supported for the first time:
- AMD Pensando Elba is a data processing unit based on Cortex-A72 CPU
cores
- Sophgo makes RISC-V based chips, and we now support the CV1800B
chip used in the milkv-duo board and the massive sg2042 chip in the
milkv-pioneer, a 64-core developer workstation.
- Qualcomm Snapdragon 720G (sm7125) is a close relative of Snapdragon
7c and gets added with some Xiaomi phones
- Renesas gains support for the R8A779F4 (R-Car S4-8) automotive SoC
and the RZ/G3S (R9A08G045) embedded SoC.
There are also a bunch of newly supported machines that use already
supported chips. On the 32-bit side, we have:
- USRobotics USR8200 is a NAS/Firewall/router based on the ancient
Intel IXP4xx platform
- A couple of machines based on the NXP i.MX5 and i.MX6 platforms
- One machine each for Allwinner V3s, Aspeed AST2600, Microchip
sama5d29 and ST STM32mp157
The other ones all use arm64 cores on chips from allwinner, amlogic,
freescale, mediatek, qualcomm and rockchip"

VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
which allows both larger device image sizes for migration, beyond
the previous 4GB limit, and also read-ahead support for improved
migration performance. (Yishai Hadas)
- A new bus master control interface for the CDX bus driver where
there is no in-band mechanism to toggle device DMA as there is
through config space on PCI devices. (Nipun Gupta)
- Add explicit alignment directives to vfio data structures to
reduce the chance of breaking 32-bit userspace. In most cases
this is transparent and the remaining cases where data structures
are padded work within the existing rules for extending data
structures within vfio. (Stefan Hajnoczi)
- Resolve a bug in the cdx bus driver noted when compiled with clang
where missing parenthesis result in the wrong operation.
(Nathan Chancellor)
- Resolve errors reported by smatch for a function when dealing
with invalid inputs. (Alex Williamson)
- Add migration support to the mtty vfio/mdev sample driver for
testing and integration purposes, allowing CI of migration without
specific hardware requirements. Also resolve many of the short-
comings of this driver relative to implementation of the vfio
interrupt ioctl along the way. (Alex Williamson)

Merge tag 'io_uring-futex-2023-10-30' of git://git.kernel.dk/linux
Pull io_uring futex support from Jens Axboe:
"This adds support for using futexes through io_uring - first futex
wake and wait, and then the vectored variant of waiting, futex waitv.
For both wait/wake/waitv, we support the bitset variant, as the
'normal' variants can be easily implemented on top of that.
PI and requeue are not supported through io_uring, just the above
mentioned parts. This may change in the future, but in the spirit of
keeping this small (and based on what people have been asking for),
this is what we currently have.
Wake support is pretty straight forward, most of the thought has gone
into the wait side to avoid needing to offload wait operations to a
blocking context. Instead, we rely on the usual callbacks to retry and
post a completion event, when appropriate.
As far as I can recall, the first request for futex support with
io_uring came from Andres Freund, working on postgres. His aio rework
of postgres was one of the early adopters of io_uring, and futex
support was a natural extension for that. This is relevant from both a
usability point of view, as well as for effiency and performance. In
Andres's words, for the former:
Futex wait support in io_uring makes it a lot easier to avoid
deadlocks in concurrent programs that have their own buffer pool:
Obviously pages in the application buffer pool have to be locked
during IO. If the initiator of IO A needs to wait for a held lock
B, the holder of lock B might wait for the IO A to complete. The
ability to wait for a lock and IO completions at the same time
provides an efficient way to avoid such deadlocks
and in terms of effiency, even without unlocking the full potential
yet, Andres says:
Futex wake support in io_uring is useful because it allows for more
efficient directed wakeups. For some "locks" postgres has queues
implemented in userspace, with wakeup logic that cannot easily be
implemented with FUTEX_WAKE_BITSET on a single "futex word"
(imagine waiting for journal flushes to have completed up to a
certain point).
Thus a "lock release" sometimes need to wake up many processes in a
row. A quick-and-dirty conversion to doing these wakeups via
io_uring lead to a 3% throughput increase, with 12% fewer context
switches, albeit in a fairly extreme workload"

regmap: prevent noinc writes from clobbering cache
Currently, noinc writes are cached as if they were standard incrementing
writes, overwriting unrelated register values in the cache. Instead, we
want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

module: Annotate struct module_notes_attrs with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct module_notes_attrs.

scripts/gdb/vmalloc: disable on no-MMU
vmap_area does not exist on no-MMU, therefore the GDB scripts fail to
load:
Traceback (most recent call last):
File "<...>/vmlinux-gdb.py", line 51, in <module>
import linux.vmalloc
File "<...>/scripts/gdb/linux/vmalloc.py", line 14, in <module>
vmap_area_ptr_type = vmap_area_type.get_type().pointer()
^^^^^^^^^^^^^^^^^^^^^^^^^
File "<...>/scripts/gdb/linux/utils.py", line 28, in get_type
self._type = gdb.lookup_type(self._name)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
gdb.error: No struct type named vmap_area.
To fix this, disable the command and add an informative error message if
CONFIG_MMU is not defined, following the example of lx-slabinfo.

On Ubuntu and probably other distros, ptrace permissions are tightend a bit by default; i.e., /proc/sys/kernel/yama/ptrace_score is set to 1. This cases memfd_secret's ptrace attach test fails with a permission error. Set it to 0 piror to running the program.

scripts/gdb: add lx_current support for riscv
csr_sscratch CSR holds current task_struct address when hart is in user
space. Trap handler on entry spills csr_sscratch into "tp" (x2) register
and zeroes out csr_sscratch CSR. Trap handler on exit reloads "tp" with
expected user mode value and place current task_struct address again in
csr_sscratch CSR.
This patch assumes "tp" is pointing to task_struct. If value in
csr_sscratch is numerically greater than "tp" then it assumes csr_sscratch
is correct address of current task_struct. This logic holds when
- hart is in user space, "tp" will be less than csr_sscratch.
- hart is in kernel space but not in trap handler, "tp" will be more
than csr_sscratch (csr_sscratch being equal to 0).
- hart is executing trap handler
- "tp" is still pointing to user mode but csr_sscratch contains
ptr to task_struct. Thus numerically higher.
- "tp" is pointing to task_struct but csr_sscratch now contains
either 0 or numerically smaller value (transiently holds
user mode tp)
