Pull block updates from Jens Axboe:
- Add a partscan attribute in sysfs, fixing an issue with systemd
relying on an internal interface that went away.
- Attempt #2 at making long running discards interruptible. The
previous attempt went into 6.9, but we ended up mostly reverting it
as it had issues.
- Remove old ida_simple API in bcache
- Support for zoned write plugging, greatly improving the performance
on zoned devices.
- Remove the old throttle low interface, which has been experimental
since 2017 and never made it beyond that and isn't being used.
- Remove page->index debugging checks in brd, as it hasn't caught
anything and prepares us for removing in struct page.
- MD pull request from Song
- Don't schedule block workers on isolated CPUs

Pull io_uring updates from Jens Axboe:
- Greatly improve send zerocopy performance, by enabling coalescing of
sent buffers.
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

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

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

- 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

- 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

Pull alpha updates from Arnd Bergmann:
"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 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 ]

Pull SoC devicetree updates from Arnd Bergmann:
"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

- Add a per-channel-path binary "ext_measurement" sysfs attribute that
provides access to extended channel-path measurement data
- Export measurement data for all channel-measurement-groups (CMG), not
only for a specific ones. 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. Make it explicit by putting into __identity_base
persistent boot variable and use it in proper context
- Introduce .amode31 section start and end macros AMODE31_START and
AMODE31_END
- Introduce OS_INFO entries that do not reference any data in memory,
but rather provide only values

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

regular kdump kernel. Enable it to be called from a stand-alone dump
kernel
- Address gcc -Warray-bounds warning and fix array size in struct
os_info
- s390 does not support SMBIOS, so drop unneeded CONFIG_DMI checks
- Use unwinder instead of __builtin_return_address() with ftrace to
prevent returning of undefined values
- Sections .hash and .gnu.hash are only created when CONFIG_PIE_BUILD
kernel is enabled. Drop these for the case CONFIG_PIE_BUILD is
disabled

Pull gpio fixes from Bartosz Golaszewski:
"Some last-minute fixes for this release from the GPIO subsystem.
The first two address a regression in performance reported to me after
the conversion to using SRCU in GPIOLIB that was merged during the
v6.9 merge window. The second patch is not technically a fix but since
after the first one we no longer need to use a per-descriptor SRCU
struct, I think it's worth to simplify the code before it gets
released on Sunday.
The next two commits fix two memory issues: one use-after-free bug and
one instance of possibly leaking kernel stack memory to user-space.
Summary:
- fix a performance regression in GPIO requesting and releasing after
the conversion to SRCU
- fix a use-after-free bug due to a race-condition
- fix leaking stack memory to user-space in a GPIO uABI corner case"

We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

If a line is requested with debounce, and that results in debouncing
in software, and the line is subsequently reconfigured to enable edge
detection then the allocation of the kfifo to contain edge events is
overlooked. This results in events being written to and read from an
uninitialised kfifo. Read events are returned to userspace.

This is the last component of encrypted tpm2 session handling that
allows us to verify from userspace that the key derived from the NULL
seed genuinely belongs to the TPM and has not been spoofed.
The procedure for doing this involves creating an attestation identity
key (which requires verification of the TPM EK certificate) and then
using that AIK to sign a certification of the Elliptic Curve key over
the NULL seed. Userspace must create this EC Key using the parameters
prescribed in TCG TPM v2.0 Provisioning Guidance for the SRK ECC; if
this is done correctly the names will match and the TPM can then run a
TPM2_Certify operation on this derived primary key using the newly
created AIK.

The final pieces of the HMAC API are for manipulating the session area
of the command. To add an authentication HMAC session
tpm_buf_append_hmac_session() is called where tpm2_append_auth() would
go. If a non empty password is passed in, this is correctly added to
the HMAC to prove knowledge of it without revealing it. Note that if
the session is only used to encrypt or decrypt parameters (no
authentication) then tpm_buf_append_hmac_session_opt() must be used
instead. This functions identically to tpm_buf_append_hmac_session()
when TPM_BUS_SECURITY is enabled, but differently when it isn't,
because effectively nothing is appended to the session area.
Next the parameters should be filled in for the command and finally
tpm_buf_fill_hmac_session() is called immediately prior to transmitting
the command which computes the correct HMAC and places it in the
command at the session location in the tpm buffer
Finally, after tpm_transmit_cmd() is called,
tpm_buf_check_hmac_response() is called to check that the returned
HMAC matched and collect the new state for the next use of the
session, if any.
The features of the session are controlled by the session attributes
set in tpm_buf_append_hmac_session(). If TPM2_SA_CONTINUE_SESSION is
not specified, the session will be flushed and the tpm2_auth structure
freed in tpm_buf_check_hmac_response(); otherwise the session may be
used again. Parameter encryption is specified by or'ing the flag
TPM2_SA_DECRYPT and response encryption by or'ing the flag
TPM2_SA_ENCRYPT. the various encryptions will be taken care of by
tpm_buf_fill_hmac_session() and tpm_buf_check_hmac_response()
respectively.

Add tpm2_append_name() for appending to the handle area of the TPM
command. When TPM_BUS_SECURITY is enabled and HMAC sessions are in
use this adds the standard u32 handle to the buffer but additionally
records the name of the object which must be used as part of the HMAC
computation. The name of certain object types (volatile and permanent
handles and NV indexes) is a hash of the public area of the object.
Since this hash is not known ahead of time, it must be requested from
the TPM using TPM2_ReadPublic() (which cannot be HMAC protected, but
if an interposer lies about it, the HMAC check will fail and the
problem will be detected).

Add session based HMAC authentication plus parameter decryption and
response encryption using AES. The basic design is to segregate all
the nasty crypto, hash and hmac code into tpm2-sessions.c and export a
usable API. The API first of all starts off by gaining a session with
tpm2_start_auth_session() which initiates a session with the TPM and
allocates an opaque tpm2_auth structure to handle the session
parameters. The design is that session use will be single threaded
from start to finish under the ops lock, so the tpm2_auth structure is
stored in struct tpm2_chip to simpify the externally visible API.
The session can be ended with tpm2_end_auth_session() which is
designed only to be used in error legs. Ordinarily the further
session API (future patches) will end or continue the session
appropriately without having to call this.

TPM2B buffers, or sized buffers, have a two byte header, which contains the
length of the payload as a 16-bit big-endian number, without counting in
the space taken by the header. This differs from encoding in the TPM header
where the length includes also the bytes taken by the header.
Unbound the length of a tpm_buf from the value stored to the TPM command

of code will grow from the current 70 lines in tpm.h to about 200
lines when the additions are done. 200 lines of inline functions is a
bit too much to keep in a header file.

The recent change to handle HAS_IOPORT removed the TPM_INF_IO_PORT
define for the HAS_IOPORT=n case despite the define being used in
sections of code not covered by the same ifdef check. This was missed
because at the moment TCG_INFINEON indirectly depends on HAS_IOPORT via
PNP which depends on ACPI || ISA. As TCG_INFINEON does in principle
support MMIO only use add it for COMPILE_TEST to cover the HAS_IOPORT=n
case.

Variable ret is being assigned and error code that is never read, it is
either being re-assigned in an error exit path or never referenced again
on the non-error path. The assignment is redundant and can be removed.

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add this dependency and ifdef sections of
code using inb()/outb() as alternative access methods.

Following the failure observed with a delay of 250us, experiments were
conducted with various delays. It was found that a delay of 350us
effectively mitigated the issue.
To provide a more optimal solution while still allowing a margin for
stability, the delay is being adjusted to 500us.

regulator_get() may sometimes be called more than once for the same
consumer device, something which before commit dbe954d8f163 ("regulator:
core: Avoid debugfs: Directory ... already present! error") resulted in
errors being logged.
A couple of recent commits broke the handling of such cases so that
attributes are now erroneously created in the debugfs root directory the
second time a regulator is requested and the log is filled with errors
like:
debugfs: File 'uA_load' in directory '/' already present!
debugfs: File 'min_uV' in directory '/' already present!
debugfs: File 'max_uV' in directory '/' already present!
debugfs: File 'constraint_flags' in directory '/' already present!
on any further calls.

DCP (Data Co-Processor) is able to derive private keys for a fused
random seed, which can be referenced by handle but not accessed by
the CPU. Similarly, DCP is able to store arbitrary keys in four
dedicated key slots located in its secure memory area (internal SRAM).
These keys can be used to perform AES encryption.
Expose these derived keys and key slots through the crypto API via their
handle. The main purpose is to add DCP-backed trusted keys. Other
use cases are possible too (see similar existing paes implementations),
but these should carefully be evaluated as e.g. enabling AF_ALG will
give userspace full access to use keys. In scenarios with untrustworthy
userspace, this will enable en-/decryption oracles.
