selftests: net: use upstream mtools
Joachim kindly merged the IPv6 support in https://github.com/troglobit/mtools/pull/2, so we can just use his version now. A few more fixes subsequently came in for IPv6, so even better. Check that the deployed mtools version is 3.0 or above. Note that the version check breaks compatibility with my fork where I didn't bump the version, but I assume that won't be a problem.

inet: fix inet_fill_ifaddr() flags truncation
I missed that (struct ifaddrmsg)->ifa_flags was only 8bits,
while (struct in_ifaddr)->ifa_flags is 32bits.
Use a temporary 32bit variable as I did in set_ifa_lifetime()
and check_lifetime().

net: phy: air_en8811h: reset netdev rules when LED is set manually
Setting LED_OFF via brightness_set should deactivate hw control, so make
sure netdev trigger rules also get cleared in that case.
This fixes unwanted restoration of the default netdev trigger rules and
matches the behaviour when using the 'netdev' trigger without any
hardware offloading.

KEYS: asymmetric: Add missing dependencies of FIPS_SIGNATURE_SELFTEST
Since the signature self-test uses RSA and SHA-256, it must only be
enabled when those algorithms are enabled. Otherwise it fails and

MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the io_uring side did not. In local testing, the crossover point for send zerocopy being faster is now around 3000 byte packets, and it performs better than the sync syscall variants as well. This feature relies on a shared branch with net-next, which was pulled into both branches. - Unification of how async preparation is done across opcodes. Previously, opcodes that required extra memory for async retry would allocate that as needed, using on-stack state until that was the case. If async retry was needed, the on-stack state was adjusted appropriately for a retry and then copied to the allocated memory. This led to some fragile and ugly code, particularly for read/write handling, and made storage retries more difficult than they needed to be. Allocate the memory upfront, as it's cheap from our pools, and use that state consistently both initially and also from the retry side. - Move away from using remap_pfn_range() for mapping the rings. This is really not the right interface to use and can cause lifetime issues or leaks. Additionally, it means the ring sq/cq arrays need to be physically contigious, which can cause problems in production with larger rings when services are restarted, as memory can be very fragmented at that point. Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply the same treatment to mapped ring provided buffers. This also helps unify the code we have dealing with allocating and mapping memory. Hard to see in the diffstat as we're adding a few features as well, but this kills about ~400 lines of code from the codebase as well. - Add support for bundles for send/recv. When used with provided buffers, bundles support sending or receiving more than one buffer at the time, improving the efficiency by only needing to call into the networking stack once for multiple sends or receives. - Tweaks for our accept operations, supporting both a DONTWAIT flag for skipping poll arm and retry if we can, and a POLLFIRST flag that the application can use to skip the initial accept attempt and rely purely on poll for triggering the operation. Both of these have identical flags on the receive side already. - Make the task_work ctx locking unconditional. We had various code paths here that would do a mix of lock/trylock and set the task_work state to whether or not it was locked. All of that goes away, we lock it unconditionally and get rid of the state flag indicating whether it's locked or not. The state struct still exists as an empty type, can go away in the future. - Add support for specifying NOP completion values, allowing it to be used for error handling testing. - Use set/test bit for io-wq worker flags. Not strictly needed, but also doesn't hurt and helps silence a KCSAN warning. - Cleanups for io-wq locking and work assignments, closing a tiny race where cancelations would not be able to find the work item reliably. - Misc fixes, cleanups, and improvements * tag 'for-6.10/io_uring-20240511' of git://git.kernel.dk/linux: (97 commits) io_uring: support to inject result for NOP io_uring: fail NOP if non-zero op flags is passed in io_uring/net: add IORING_ACCEPT_POLL_FIRST flag io_uring/net: add IORING_ACCEPT_DONTWAIT flag io_uring/filetable: don't unnecessarily clear/reset bitmap io_uring/io-wq: Use set_bit() and test_bit() at worker->flags io_uring/msg_ring: cleanup posting to IOPOLL vs !IOPOLL ring io_uring: Require zeroed sqe->len on provided-buffers send io_uring/notif: disable LAZY_WAKE for linked notifs io_uring/net: fix sendzc lazy wake polling io_uring/msg_ring: reuse ctx->submitter_task read using READ_ONCE instead of re-reading it io_uring/rw: reinstate thread check for retries io_uring/notif: implement notification stacking io_uring/notif: simplify io_notif_flush() net: add callback for setting a ubuf_info to skb net: extend ubuf_info callback to ops structure io_uring/net: support bundles for recv io_uring/net: support bundles for send io_uring/kbuf: add helpers for getting/peeking multiple buffers io_uring/net: add provided buffer support for IORING_OP_SEND ... |

Merge tag 'vfs-6.10.netfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This reworks the netfslib writeback implementation so that pages read
from the cache are written to the cache through ->writepages(),
thereby allowing the fscache page flag to be retired.
The reworking also:
- builds on top of the new writeback_iter() infrastructure
- makes it possible to use vectored write RPCs as discontiguous
streams of pages can be accommodated
- makes it easier to do simultaneous content crypto and stream
division
- provides support for retrying writes and re-dividing a stream
- replaces the ->launder_folio() op, so that ->writepages() is used
instead
- uses mempools to allocate the netfs_io_request and
netfs_io_subrequest structs to avoid allocation failure in the
writeback path
Some code that uses the fscache page flag is retained for
compatibility purposes with nfs and ceph. The code is switched to
using the synonymous private_2 label instead and marked with
deprecation comments.
The merge commit contains additional details on the new algorithm that
I've left out of here as it would probably be excessively detailed.
On top of the netfslib infrastructure this contains the work to
convert cifs over to netfslib"

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice
Fixes:
- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation
- Fix overly long line in xfs file_operations (follow-up to FMODE_*
cleanup)
- Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up
to FMODE_* cleanup)
- Don't call xfs_file_open from xfs_dir_open (follow-up to FMODE_*
cleanup)
- Fix stable offset api to prevent endless loops
- Fix afs file server rotations
- Prevent xattr node from overflowing the eraseblock in jffs2
- Move fdinfo PTRACE_MODE_READ procfs check into the .permission()
operation instead of .open() operation since this caused userspace
regressions"

Merge tag 'slab-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
"This time it's mostly random cleanups and fixes, with two performance
fixes that might have significant impact, but limited to systems
experiencing particular bad corner case scenarios rather than general
performance improvements.
The memcg hook changes are going through the mm tree due to
dependencies.
- Prevent stalls when reading /proc/slabinfo (Jianfeng Wang)
This fixes the long-standing problem that can happen with workloads
that have alloc/free patterns resulting in many partially used
slabs (in e.g. dentry cache). Reading /proc/slabinfo will traverse
the long partial slab list under spinlock with disabled irqs and
thus can stall other processes or even trigger the lockup
detection. The traversal is only done to count free objects so that
<active_objs> column can be reported along with <num_objs>.
To avoid affecting fast paths with another shared counter
(attempted in the past) or complex partial list traversal schemes
that allow rescheduling, the chosen solution resorts to
approximation - when the partial list is over 10000 slabs long, we
will only traverse first 5000 slabs from head and tail each and use
the average of those to estimate the whole list. Both head and tail
are used as the slabs near head to tend to have more free objects
than the slabs towards the tail.
It is expected the approximation should not break existing
/proc/slabinfo consumers. The <num_objs> field is still accurate
and reflects the overall kmem_cache footprint. The <active_objs>
was already imprecise due to cpu and percpu-partial slabs, so can't
be relied upon to determine exact cache usage. The difference
between <active_objs> and <num_objs> is mainly useful to determine
the slab fragmentation, and that will be possible even with the
approximation in place.
- Prevent allocating many slabs when a NUMA node is full (Chen Jun)
Currently, on NUMA systems with a node under significantly bigger
pressure than other nodes, the fallback strategy may result in each
kmalloc_node() that can't be safisfied from the preferred node, to
allocate a new slab on a fallback node, and not reuse the slabs
already on that node's partial list.
This is now fixed and partial lists of fallback nodes are checked
even for kmalloc_node() allocations. It's still preferred to
allocate a new slab on the requested node before a fallback, but
only with a GFP_NOWAIT attempt, which will fail quickly when the
node is under a significant memory pressure.
- More SLAB removal related cleanups (Xiu Jianfeng, Hyunmin Lee)
- Fix slub_kunit self-test with hardened freelists (Guenter Roeck)
- Mark racy accesses for KCSAN (linke li)
- Misc cleanups (Xiongwei Song, Haifeng Xu, Sangyun Kim)"

kcsan: Introduce __data_racy type qualifier
This commit adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access. This allows pre-KCSAN code to be correctly (if approximately) instrumented withh very little effort, and also provides people reading the code a clear indication that the variable is in fact shared. In addition, it permits incremental transition to per-access KCSAN marking, so that (for example) a given subsystem can be transitioned one variable at a time, while avoiding large numbers of KCSAN warnings during this transition. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmY+i+cTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jJQ1D/9eOBNKefU7duZgAOzUizPdxRvxKzPx UENz6DU/xXB+jcaWiRvdWyFgIFnUS/TaZcwtthXh4bV1I754dRFy8X9+/uHd8AVY MUwRkhY3Nie/MgkvLrEmMsfWn9zSUp0Pwq4dwFdhvb0aosFSn7PgtSrE62+RafpZ k1abEUa62MfSLJjJ7C8ThYk9broAgz37drloAStAr4PvrCM4JaoeChkStaAK80z1 qq3EblLtXlzKcW1UNkvsbTxcnv+quLsI4EHKSnN3O8l47/F/k52ENz5Qp1pYTOLk kO3IZjqFqnIH6Re5eHPA05cwQssJFvsB8gfB+g+kc2uOK/z7wwg0/gqf9SZyaosw ABoaxflfNE/mTzKVgob3wqGyhlsAE/R2k02yoMad4X78ATOi9RpjdH6xC4OOXYfV 4P8g2hGAHNR8UgYosXFx+YCu2ktGYyfsqTicMaaaECUfxFeJjJ1QqgwHYHADDDv/ x8UxggAco1jul+6fikPGnjDgBN5IJOwS26NEUguqAFqYMTF8OO/x6ag6cqG5nk3a b41GF4HEfoQtJduuOv8jVntyTRU7zbpH+AVuinQ1V34kpYp5fE75p30P4UUjMegA JaAoOeD9aebEUHHlujomaV/QKSHobYLmYp/ARe2QZjp7aiELcjvV/ThOdwRxGEZg Zl4qRaGc9YO/Ag== =f1gr -----END PGP SIGNATURE----- Merge tag 'kcsan.2024.05.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull kcsan update from Paul McKenney: "Introduce __data_racy type qualifier This adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access.

sparc32,parisc,csky: Provide one-byte and two-byte cmpxchg() support
This series provides native one-byte and two-byte cmpxchg() support
for sparc32 and parisc, courtesy of Al Viro. This support is provided
by the same hashed-array-of-locks technique used for the other atomic
operations provided for these two platforms.
This series also provides emulated one-byte cmpxchg() support for csky
using a new cmpxchg_emu_u8() function that uses a four-byte cmpxchg()
to emulate the one-byte variant.
Similar patches for emulation of one-byte cmpxchg() for arc, sh, and
xtensa have not yet received maintainer acks, so they are slated for
the v6.11 merge window.

selftests/user_events: Add non-spacing separator check
The ABI documentation indicates that field separators do not need a space between them, only a ';'. When no spacing is used, the register must work. Any subsequent register, with or without spaces, must match and not return -EADDRINUSE. Add a non-spacing separator case to our self-test register case to ensure it works going forward.

tracing/user_events: Fix non-spaced field matching
When the ABI was updated to prevent same name w/different args, it
missed an important corner case when fields don't end with a space.
Typically, space is used for fields to help separate them, like
"u8 field1; u8 field2". If no spaces are used, like
"u8 field1;u8 field2", then the parsing works for the first time.
However, the match check fails on a subsequent register, leading to
confusion.
This is because the match check uses argv_split() and assumes that all
fields will be split upon the space. When spaces are used, we get back
{ "u8", "field1;" }, without spaces we get back { "u8", "field1;u8" }.
This causes a mismatch, and the user program gets back -EADDRINUSE.
Add a method to detect this case before calling argv_split(). If found
force a space after the field separator character ';'. This ensures all
cases work properly for matching.
With this fix, the following are all treated as matching:
u8 field1;u8 field2
u8 field1; u8 field2
u8 field1;\tu8 field2
u8 field1;\nu8 field2

alpha: cleanups and build fixes
I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family
in the kernel without native byte access and that Debian has already
dropped support for this generation last year [1] in order to
improve performance for the newer machines.
This topic came up again when Paul E. McKenney noticed that
parts of the RCU code already rely on byte access and do not
work on alpha EV5 reliably, so we decided on using my series to
avoid the problem entirely.
Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts and allow
backporting the fixes to stable kernels for the now removed hardware
support as well.

[ I dearly loved alpha back in the days, but the lack of byte and word
operations was a horrible mistake and made everything worse -
including very much the crazy IO contortions that resulted from it.
It certainly wasn't the only mistake in the architecture, but it's the
first-order issue.
So while it's a bit sad to see the support for my first alpha go away,
if you want to run museum hardware, maybe you should use museum
kernels.. - Linus ]

soc: drivers for 6.10
As usual, these are updates for drivers that are specific to certain
SoCs or firmware running on them. Notable updates include
- The new STMicroelectronics STM32 "firewall" bus driver that is
used to provide a barrier between different parts of an SoC
- Lots of updates for the Qualcomm platform drivers, in particular
SCM, which gets a rewrite of its initialization code
- Firmware driver updates for Arm FF-A notification interrupts
and indirect messaging, SCMI firmware support for pin control
and vendor specific interfaces, and TEE firmware interface
changes across multiple TEE drivers
- A larger cleanup of the Mediatek CMDQ driver and some related bits
- Kconfig changes for riscv drivers to prepare for adding Kanaan
k230 support
- Multiple minor updates for the TI sysc bus driver, memory controllers,
hisilicon hccs and more

soc: devicetree updates for 6.10, part 1
The updates this time are a bit smaller than most times, mainly because
it is not totally dominated by new Qualcomm hardware support. Instead,
we larger than average updates for Rockchips, NXP, Allwinner and TI.
The only two new SoCs this time are both from NXP and are minor variants
of already supported ones.
The updates for aspeed, amlogic and mediatek came a little late, so
I'm saving those for part 2 in a few days if everything turns out fine.
New machines this time contain:
- two Broadcom SoC based wireless routers from Asus
- Five allwinner based consumer devices for gaming, set-top-box and
eboot reader applications
- Three older phones based on Qualcomm chips, plus the more recent
Sony Xperia 1 V
- 14 industrial and embedded boards based on NXP i.MX6, i.MX8,
layerscape and s32g3 SoCs
- six rockchips boards including another handheld game console
and a few single-board computers
On top of these, we have the usual cleanups for dtc warnings and
updates to add more features to already merged machines.

This enables support of new CMG data formats in userspace without the need for kernel changes - Add a per-channel-path sysfs attribute "speed_bps" that provides the operating speed in bits per second or 0 if the operating speed is not available - The CIO tracepoint subchannel-type field "st" is incorrectly set to the value of subchannel-enabled SCHIB "ena" field. Fix that - Do not forcefully limit vmemmap starting address to MAX_PHYSMEM_BITS - Consider the maximum physical address available to a DCSS segment (512GB) when memory layout is set up - Simplify the virtual memory layout setup by reducing the size of identity mapping vs vmemmap overlap - Swap vmalloc and Lowcore/Real Memory Copy areas in virtual memory. This will allow to place the kernel image next to kernel modules - Move everyting KASLR related from <asm/setup.h> to <asm/page.h> - Put virtual memory layout information into a structure to improve code generation - Currently __kaslr_offset is the kernel offset in both physical and virtual memory spaces. Uncouple these offsets to allow uncoupling of the addresses spaces - Currently the identity mapping base address is implicit and is always set to zero.

It is read out by makedumpfile, crash and other tools - Store virtual memory layout in VMCORE_INFO. It is read out by crash and other tools when /proc/kcore device is used - Create additional PT_LOAD ELF program header that covers kernel image only, so that vmcore tools could locate kernel text and data when virtual and physical memory spaces are uncoupled - Uncouple physical and virtual address spaces - Map kernel at fixed location when KASLR mode is disabled. The location is defined by CONFIG_KERNEL_IMAGE_BASE kernel configuration value. - Rework deployment of kernel image for both compressed and uncompressed variants as defined by CONFIG_KERNEL_UNCOMPRESSED kernel configuration value - Move .vmlinux.relocs section in front of the compressed kernel. The interim section rescue step is avoided as result - Correct modules thunk offset calculation when branch target is more than 2GB away - Kernel modules contain their own set of expoline thunks. Now that the kernel modules area is less than 4GB away from kernel expoline thunks, make modules use kernel expolines. Also make EXPOLINE_EXTERN the default if the compiler supports it - userfaultfd can insert shared zeropages into processes running VMs, but that is not allowed for s390. Fallback to allocating a fresh zeroed anonymous folio and insert that instead - Re-enable shared zeropages for non-PV and non-skeys KVM guests - Rename hex2bitmap() to ap_hex2bitmap() and export it for external use - Add ap_config sysfs attribute to provide the means for setting or displaying adapters, domains and control domains assigned to a vfio-ap mediated device in a single operation - Make vfio_ap_mdev_link_queue() ignore duplicate link requests - Add write support to ap_config sysfs attribute to allow atomic update a vfio-ap mediated device state - Document ap_config sysfs attribute - Function os_info_old_init() is expected to be called only from a regular kdump kernel.

of: property: Add fw_devlink support for interrupt-map property
Some of the PCI host controllers (such as generic PCI host controller) use "interrupt-map" DT property to describe the mapping between PCI endpoints and PCI interrupt pins. This is the only case where the interrupts are not described in DT. Currently, there is no fw_devlink created based on "interrupt-map" DT property so interrupt controller is not guaranteed to be probed before the PCI host controller. This affects every platform where both PCI host controller and interrupt controllers are probed as regular platform devices. This creates fw_devlink between consumers (PCI host controller) and supplier (interrupt controller) based on "interrupt-map" DT property.

dt-bindings: display: panel: constrain 'reg' in DSI panels
DSI-attached devices could respond to more than one virtual channel number, thus their bindings are supposed to constrain the 'reg' property to match hardware. Add missing 'reg' constrain for DSI-attached display panels, based on DTS sources in Linux kernel (assume all devices take only one channel number).

dmaengine: idxd: add a write() method for applications to submit work
After the patch to restrict the use of mmap() to CAP_SYS_RAWIO for
the currently existing devices, most applications can no longer make
use of the accelerators as in production "you don't run things as root".
To keep the DSA and IAA accelerators usable, hook up a write() method
so that applications can still submit work. In the write method,
sufficient input validation is performed to avoid the security issue
that required the mmap CAP_SYS_RAWIO check.
One complication is that the DSA device allows for indirect ("batched")
descriptors. There is no reasonable way to do the input validation
on these indirect descriptors so the write() method will not allow these
to be submitted to the hardware on affected hardware, and the sysfs
enumeration of support for the opcode is also removed.
Early performance data shows that the performance delta for most common
cases is within the noise.

dmaengine: idxd: add a new security check to deal with a hardware erratum
On Sapphire Rapids and related platforms, the DSA and IAA devices have an erratum that causes direct access (for example, by using the ENQCMD or MOVDIR64 instructions) from untrusted applications to be a security problem. To solve this, add a flag to the PCI device enumeration and device structures to indicate the presence/absence of this security exposure. In the mmap() method of the device, this flag is then used to enforce that the user has the CAP_SYS_RAWIO capability. In a future patch, a write() based method will be added that allows untrusted applications submit work to the accelerator, where the kernel can do sanity checking on the user input to ensure secure operation of the accelerator.

VFIO: Add the SPR_DSA and SPR_IAX devices to the denylist
Due to an erratum with the SPR_DSA and SPR_IAX devices, it is not secure to assign these devices to virtual machines. Add the PCI IDs of these devices to the VFIO denylist to ensure that this is handled appropriately by the VFIO subsystem. The SPR_DSA and SPR_IAX devices are on-SOC devices for the Sapphire Rapids (and related) family of products that perform data movement and compression.
