Pull misc vfs updates from Christian Brauner:
"This contains the usual pile of misc updates:
Features:
- Add F_CREATED_QUERY fcntl() that allows userspace to query whether
a file was actually created. 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. Instead of
using the bit based wait apis we're now using the var event apis
and using the individual bytes of the i_state member to wait on
state changes
- Explain how per-syscall AT_* flags should be allocated
- Use in_group_or_capable() helper to simplify the posix acl mode
update code
- Switch to LIST_HEAD() in fsync_buffers_list() to simplify the code
- Removed comment about d_rcu_to_refcount() as that function doesn't
exist anymore
- Add kernel documentation for lookup_fast()
- Don't re-zero evenpoll fields
- Remove outdated comment after close_fd()
- Fix imprecise wording in comment about the pipe filesystem
- Drop GFP_NOFAIL mode from alloc_page_buffers
- Missing blank line warnings and struct declaration improved in
file_table
- Annotate struct poll_list with __counted_by()
- Remove the unused read parameter in percpu-rwsem
- Remove linux/prefetch.h include from direct-io code
- Use kmemdup_array instead of kmemdup for multiple allocation in
mnt_idmapping code
- Remove unused mnt_cursor_del() declaration
Performance tweaks:
- Dodge smp_mb in break_lease and break_deleg in the common case
- Only read fops once in fops_{get,put}()
- Use RCU in ilookup()
- Elide smp_mb in iversion handling in the common case
- Drop one lock trip in evict()"

Pull power management updates from Rafael Wysocki:
"By the number of new lines of code, the most visible change here is
the addition of hybrid CPU capacity scaling support to the
intel_pstate driver. Next are the amd-pstate driver changes related to
the calculation of the AMD boost numerator and preferred core
detection.
As far as new hardware support is concerned, the intel_idle driver
will now handle Granite Rapids Xeon processors natively, the
intel_rapl power capping driver will recognize family 1Ah of AMD
processors and Intel ArrowLake-U chipos, and intel_pstate will handle
Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.
Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.

using memory protection keys, support for running as a protected guest
on Android as well as perf support for a bunch of new interconnect
PMUs.
Summary:
ACPI:
- Enable PMCG erratum workaround for HiSilicon HIP10 and 11
platforms.
- Ensure arm64-specific IORT header is covered by MAINTAINERS.
CPU Errata:
- Enable workaround for hardware access/dirty issue on Ampere-1A
cores.
Memory management:
- Define PHYSMEM_END to fix a crash in the amdgpu driver.
- Avoid tripping over invalid kernel mappings on the kexec() path.
- Userspace support for the Permission Overlay Extension (POE) using
protection keys.
Perf and PMUs:
- Add support for the "fixed instruction counter" extension in the
CPU PMU architecture.
- Extend and fix the event encodings for Apple's M1 CPU PMU.
- Allow LSM hooks to decide on SPE permissions for physical
profiling.
- Add support for the CMN S3 and NI-700 PMUs.
Confidential Computing:
- Add support for booting an arm64 kernel as a protected guest under
Android's "Protected KVM" (pKVM) hypervisor.
Selftests:
- Fix vector length issues in the SVE/SME sigreturn tests
- Fix build warning in the ptrace tests.
Timers:
- Add support for PR_{G,S}ET_TSC so that 'rr' can deal with
non-determinism arising from the architected counter.
Miscellaneous:
- Rework our IPI-based CPU stopping code to try NMIs if regular IPIs
don't succeed.
- Minor fixes and cleanups"

selftests: add ncdevmem, netcat for devmem TCP
ncdevmem is a devmem TCP netcat. It works similarly to netcat, but it sends and receives data using the devmem TCP APIs. It uses udmabuf as the dmabuf provider. It is compatible with a regular netcat running on a peer, or a ncdevmem running on a peer. In addition to normal netcat support, ncdevmem has a validation mode, where it sends a specific pattern and validates this pattern on the receiver side to ensure data integrity.

selftests: mptcp: include net_helper.sh file
Similar to the previous commit, the net_helper.sh file from the parent
directory is used by the MPTCP selftests and it needs to be present when
running the tests.
This file then needs to be listed in the Makefile to be included when
exporting or installing the tests, e.g. with:
make -C tools/testing/selftests \

selftests/bpf: Expand skb dynptr selftests for tp_btf
Add 3 test cases for skb dynptr used in tp_btf: - test_dynptr_skb_tp_btf: use skb dynptr in tp_btf and make sure it is read-only. - skb_invalid_ctx_fentry/skb_invalid_ctx_fexit: bpf_dynptr_from_skb should fail in fentry/fexit. In test_dynptr_skb_tp_btf, to trigger the tracepoint in kfree_skb, test_pkt_access is used for its test_run, as in kfree_skb.c. Because the test process is different from others, a new setup type is defined, i.e., SETUP_SKB_PROG_TP. The result is like: $ ./test_progs -t 'dynptr/test_dynptr_skb_tp_btf' #84/14 dynptr/test_dynptr_skb_tp_btf:OK #84 dynptr:OK #127 kfunc_dynptr_param:OK Summary: 2/1 PASSED, 0 SKIPPED, 0 FAILED $ ./test_progs -t 'dynptr/skb_invalid_ctx_f' #84/85 dynptr/skb_invalid_ctx_fentry:OK #84/86 dynptr/skb_invalid_ctx_fexit:OK #84 dynptr:OK #127 kfunc_dynptr_param:OK Summary: 2/2 PASSED, 0 SKIPPED, 0 FAILED Also fix two coding style nits (change spaces to tabs).

selftests/xsk: Read current MAX_SKB_FRAGS from sysctl knob
Currently, xskxceiver assumes that MAX_SKB_FRAGS value is always 17 which is not true - since the introduction of BIG TCP this can now take any value between 17 to 45 via CONFIG_MAX_SKB_FRAGS. Adjust the TOO_MANY_FRAGS test case to read the currently configured MAX_SKB_FRAGS value by reading it from /proc/sys/net/core/max_skb_frags. If running system does not provide that sysctl file then let us try running the test with a default value.

selftests: net: csum: Fix checksums for packets with non-zero padding
Padding is not included in UDP and TCP checksums. Therefore, reduce the
length of the checksummed data to include only the data in the IP
payload. This fixes spurious reported checksum failures like
rx: pkt: sport=33000 len=26 csum=0xc850 verify=0xf9fe
pkt: bad csum
Technically it is possible for there to be trailing bytes after the UDP
data but before the Ethernet padding (e.g. if sizeof(ip) + sizeof(udp) +
udp.len < ip.len). However, we don't generate such packets.

selftests: support interpreted scripts with ksft_runner.sh
Support testcases that are themselves not executable, but need an
interpreter to run them.
If a test file is not executable, but an executable file
ksft_runner.sh exists in the TARGET dir, kselftest will run
./ksft_runner.sh ./$BASENAME_TEST
Packetdrill may add hundreds of packetdrill scripts for testing. These
scripts must be passed to the packetdrill process.
Have kselftest run each test directly, as it already solves common
runner requirements like parallel execution and isolation (netns).
A previous RFC added a wrapper in between, which would have to
reimplement such functionality.

The scenario is
1. send(MSG_OOB)
2. recv(MSG_OOB)
-> The consumed OOB remains in recv queue
3. send(MSG_OOB)
4. recv()
-> manage_oob() returns the next skb of the consumed OOB
-> This is also OOB, but unix_sk(sk)->oob_skb is not cleared
5. recv(MSG_OOB)

selftests: mptcp: connect: remove duplicated spaces in TAP output
It is nice to have a visual alignment in the test output to present the different results, but it makes less sense in the TAP output that is there for computers. It sounds then better to remove the duplicated whitespaces in the TAP output, also because it can cause some issues with TAP parsers expecting only one space around the directive delimiter (#). While at it, change the variable name (result_msg) to something more explicit.

selftests: return failure when timestamps can't be reported
When I was trying to modify the tx timestamping feature, I found that
running "./txtimestamp -4 -C -L 127.0.0.1" didn't reflect the error:
I succeeded to generate timestamp stored in the skb but later failed
to report it to the userspace (which means failed to put css into cmsg).
It can happen when someone writes buggy codes in __sock_recv_timestamp(),
for example.
After adding the check so that running ./txtimestamp will reflect the
result correctly like this if there is a bug in the reporting phase:
protocol: TCP
payload: 10
server port: 9000
family: INET
test SND
USR: 1725458477 s 667997 us (seq=0, len=0)
Failed to report timestamps
USR: 1725458477 s 718128 us (seq=0, len=0)

Failed to report timestamps
USR: 1725458477 s 818416 us (seq=0, len=0)

...
In the future, it will help us detect whether the new coming patch has
bugs or not.

* A revert for the mmap() change that ties the allocation range to the hint adress, as what we tried to do ended up regressing on other userspace workloads. * A fix to avoid a kernel memory leak when emulating misaligned accesses from userspace. * A Kconfig fix for toolchain vector detection, which now correctly detects vector support on toolchains where the V extension depends on the M extension. * A fix to avoid failing the linear mapping bootmem bounds check on NOMMU systems. * A fix for early alternatives on relocatable kernels. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmbbD44THHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiRR/EACqW46mbTmGrbDzbk2YcKbkc05djuB2 +yorDaO6d188xmHM74zEvt1+X+Mxj18pMm+V02L+27JA7asv+JugXQVwfxtZ769w /XMKGrJTUCMSvFpsbhszbse3vXjc1F9uQ5wNa9o44MHAc2twSkJHtdhZJwkJJ9ru Od0m99VXWB1gbA1hvCpQBs2uMSzLoU5X2//AaAzVFK1pyskZ7HPqFX16eFcT0gpA GDNYIKLPVF1pcwS2gkQM7LAwveCsxuEdnLufJs5Coz9BZ/kQJPd3sK/z8Z58ghy2 Db6XXtcYJs64Ndjv1MSowb4rIii/BN2vlMCCT95xHH+tuJR6flXuIZQPpI971V/A XOCglNQQkmzjJuFKn1/9ZJcVZGITOqDX37iMPW/3bQ/OFG0emBeGqYXKMmScI6f1 TtqiByz2VXNEJBNkQVA37Cj42DVmRg3MCjwy0ACLbqBpMeSbGK7MRNUk258wOp4V ucmhf50D3a0w8y/3miaAH1Pk+tZz/rtVFkdbibDW3M91cOfdNoAYKhSJPEEnhaGm pVTvW+usKDdim3nqqTrlZTfFTNF7wFkvoDc11lStgYFK8VoZWuyoBcf1LQ2+ghv9 qP/A5LRnWU4nXCxZG6dKRoZ/VvoGtsKdI6Iatnak4cAbsvXI+7foelgLgWY6aFzk /ZUtSmWDz1E21Q== =xYax -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-6.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fixes from Palmer Dabbelt: - A revert for the mmap() change that ties the allocation range to the hint adress, as what we tried to do ended up regressing on other userspace workloads. - A fix to avoid a kernel memory leak when emulating misaligned accesses from userspace. - A Kconfig fix for toolchain vector detection, which now correctly detects vector support on toolchains where the V extension depends on the M extension. - A fix to avoid failing the linear mapping bootmem bounds check on NOMMU systems. - A fix for early alternatives on relocatable kernels. * tag 'riscv-for-linus-6.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: Fix RISCV_ALTERNATIVE_EARLY riscv: Do not restrict memory size because of linear mapping on nommu riscv: Fix toolchain vector detection riscv: misaligned: Restrict user access to kernel memory riscv: mm: Do not restrict mmap address based on hint riscv: selftests: Remove mmap hint address checks Revert "RISC-V: mm: Document mmap changes" |

pm:cpupower: Add SWIG bindings files for libcpupower
SWIG is a tool packaged in Fedora and other distros that can generate bindings from C and C++ code for several languages including Python, Perl, and Go. These bindings allows users to easily write scripts that use and extend libcpupower's functionality. Currently, only Python is provided in the makefile, but additional languages may be added if there is demand. Added suggestions from Shuah Khan for the README and license discussion. Note that while SWIG itself is GPL v3+ licensed; the resulting output, the bindings code, is permissively licensed + the license of the .o files. Please see https://swig.org/legal.html and [1] for more details.

pm:cpupower: Add missing powercap_set_enabled() stub function
There was a symbol listed in the powercap.h file that was not implemented.
Implement it with a stub return of 0.
Programs like SWIG require that functions that are defined in the
headers be implemented.

Including fixes from can, bluetooth and wireless.
No known regressions at this point. Another calm week, but chances are
that has more to do with vacation season than the quality of our work.
Current release - new code bugs:
- smc: prevent NULL pointer dereference in txopt_get
- eth: ti: am65-cpsw: number of XDP-related fixes
Previous releases - regressions:
- Revert "Bluetooth: MGMT/SMP: Fix address type when using SMP over
BREDR/LE", it breaks existing user space
- Bluetooth: qca: if memdump doesn't work, re-enable IBS to avoid
later problems with suspend
- can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open
- eth: r8152: fix the firmware communication error due to use
of bulk write
- ptp: ocp: fix serial port information export
- eth: igb: fix not clearing TimeSync interrupts for 82580
- Revert "wifi: ath11k: support hibernation", fix suspend on Lenovo
Previous releases - always broken:
- eth: intel: fix crashes and bugs when reconfiguration and resets
happening in parallel
- wifi: ath11k: fix NULL dereference in ath11k_mac_get_eirp_power()
Misc:
- docs: netdev: document guidance on cleanup.h

tools/net/ynl: fix cli.py --subscribe feature
Execution of command:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml /
--subscribe "monitor" --sleep 10
fails with:
File "/repo/./tools/net/ynl/cli.py", line 109, in main
ynl.check_ntf()
File "/repo/tools/net/ynl/lib/ynl.py", line 924, in check_ntf
op = self.rsp_by_value[nl_msg.cmd()]
KeyError: 19
Parsing Generic Netlink notification messages performs lookup for op in
the message. The message was not yet decoded, and is not yet considered
GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of
proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13).
Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the
op was not passed to the decode function, thus allow parsing of Generic
Netlink notifications without causing the failure.
