Sean Christopherson 625646aede KVM: selftests: Use pread() to read binary stats header
Use pread() with an explicit offset when reading the header and the header
name for a binary stats fd so that the common helper and the binary stats
test don't subtly rely on the file effectively being untouched, e.g. to
allow multiple reads of the header, name, etc.

Sean Christopherson 3bcbc20942 selftests/rseq: Play nice with binaries statically linked against glibc 2.35+
To allow running rseq and KVM's rseq selftests as statically linked
binaries, initialize the various "trampoline" pointers to point directly
at the expect glibc symbols, and skip the dlysm() lookups if the rseq
size is non-zero, i.e. the binary is statically linked *and* the libc
registered its own rseq.

Define weak versions of the symbols so as not to break linking against
libc versions that don't support rseq in any capacity.

The KVM selftests in particular are often statically linked so that they
can be run on targets with very limited runtime environments, i.e. test
machines.

Matthieu Baerts 031c99e71f selftests: tc: add ConnTrack procfs kconfig
When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

  not ok 373 3992 - Add ct action triggering DNAT tuple conflict
  	Could not match regex pattern. Verify command output:
  cat: /proc/net/nf_conntrack: No such file or directory

It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

Matthieu Baerts 719b4774a8 selftests: tc: add 'ct' action kconfig dep
When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.

Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

Matthieu Baerts fda05798c2 selftests: tc: set timeout to 15 minutes
When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:

  not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds

The timeout had been introduced 3 years ago, see the Fixes commit below.

This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.

The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

John Hubbard 569f8b501b selftests/arm64: fix build failure during the "emit_tests" step
The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.

This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".

That approach worked for years. But with 9fc96c7c19 in place,
emit_tests failed, because it does not set up all of the elaborate
things that "install" does. And that caused the new
"kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being
correct) to fail.

Some detail: The "all" target is .PHONY. Therefore, each target that
depends on "all" will cause it to be invoked again, and because
dependencies are managed quite loosely in the selftests Makefiles, many
things will run, even "all" is invoked several times in immediate
succession. So this is not a "real" failure, as far as build steps go:
everything gets built, but "all" reports a problem when invoked a second
time from a bad environment.

To fix this, simply remove the unnecessary "all" dependency from the
overridden emit_tests target. The dependency is still effectively
honored, because again, invocation is via "install", which also depends
upon "all".

An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

John Hubbard c77896b143 selftests/riscv: fix potential build failure during the "emit_tests" step
The riscv selftests (which were modeled after the arm64 selftests) are
improperly declaring the "emit_tests" target to depend upon the "all"
target. This approach, when combined with commit 9fc96c7c19
("selftests: error out if kernel header files are not yet built"), has
caused build failures [1] on arm64, and is likely to cause similar
failures for riscv.

To fix this, simply remove the unnecessary "all" dependency from the
emit_tests target. The dependency is still effectively honored, because
again, invocation is via "install", which also depends upon "all".

An alternative approach would be to harden the emit_tests target so that

Linus Torvalds ebc27aacee Tracing fixes and clean ups:
- Fix some missing-prototype warnings
 
 - Fix user events struct args (did not include size of struct)
   When creating a user event, the "struct" keyword is to denote
   that the size of the field will be passed in. But the parsing
   failed to handle this case.
 
 - Add selftest to struct sizes for user events
 
 - Fix sample code for direct trampolines.
   The sample code for direct trampolines attached to handle_mm_fault().
   But the prototype changed and the direct trampoline sample code
   was not updated. Direct trampolines needs to have the arguments correct
   otherwise it can fail or crash the system.
 
 - Remove unused ftrace_regs_caller_ret() prototype.
 
 - Quiet false positive of FORTIFY_SOURCE
   Due to backward compatibility, the structure used to save stack traces
   in the kernel had a fixed size of 8. This structure is exported to
   user space via the tracing format file. A change was made to allow
   more than 8 functions to be recorded, and user space now uses the
   size field to know how many functions are actually in the stack.
   But the structure still has size of 8 (even though it points into
   the ring buffer that has the required amount allocated to hold a
   full stack. This was fine until the fortifier noticed that the
   memcpy(&entry->caller, stack, size) was greater than the 8 functions
   and would complain at runtime about it. Hide this by using a pointer
   to the stack location on the ring buffer instead of using the address
   of the entry structure caller field.
 
 - Fix a deadloop in reading trace_pipe that was caused by a mismatch
   between ring_buffer_empty() returning false which then asked to
   read the data, but the read code uses rb_num_of_entries() that
   returned zero, and causing a infinite "retry".
 
 - Fix a warning caused by not using all pages allocated to store
   ftrace functions, where this can happen if the linker inserts a bunch of
   "NULL" entries, causing the accounting of how many pages needed
   to be off.
 
 - Fix histogram synthetic event crashing when the start event is
   removed and the end event is still using a variable from it.
 
 - Fix memory leak in freeing iter->temp in tracing_release_pipe()

Merge tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:

 - Fix some missing-prototype warnings

 - Fix user events struct args (did not include size of struct)

   When creating a user event, the "struct" keyword is to denote that
   the size of the field will be passed in. But the parsing failed to
   handle this case.

 - Add selftest to struct sizes for user events

 - Fix sample code for direct trampolines.

   The sample code for direct trampolines attached to handle_mm_fault().
   But the prototype changed and the direct trampoline sample code was
   not updated. Direct trampolines needs to have the arguments correct
   otherwise it can fail or crash the system.

 - Remove unused ftrace_regs_caller_ret() prototype.

 - Quiet false positive of FORTIFY_SOURCE

   Due to backward compatibility, the structure used to save stack
   traces in the kernel had a fixed size of 8. This structure is
   exported to user space via the tracing format file. A change was made
   to allow more than 8 functions to be recorded, and user space now
   uses the size field to know how many functions are actually in the
   stack.

   But the structure still has size of 8 (even though it points into the
   ring buffer that has the required amount allocated to hold a full
   stack.

   This was fine until the fortifier noticed that the
   memcpy(&entry->caller, stack, size) was greater than the 8 functions
   and would complain at runtime about it.

   Hide this by using a pointer to the stack location on the ring buffer
   instead of using the address of the entry structure caller field.

 - Fix a deadloop in reading trace_pipe that was caused by a mismatch
   between ring_buffer_empty() returning false which then asked to read
   the data, but the read code uses rb_num_of_entries() that returned
   zero, and causing a infinite "retry".

 - Fix a warning caused by not using all pages allocated to store ftrace
   functions, where this can happen if the linker inserts a bunch of
   "NULL" entries, causing the accounting of how many pages needed to be
   off.

 - Fix histogram synthetic event crashing when the start event is
   removed and the end event is still using a variable from it

 - Fix memory leak in freeing iter->temp in tracing_release_pipe()

Matthieu Baerts 61d9658050 selftests: mptcp: pm_nl_ctl: fix 32-bit support
When using pm_nl_ctl to validate userspace path-manager's behaviours, it
was failing on 32-bit architectures ~half of the time.

pm_nl_ctl was not reporting any error but the command was not doing what
it was expected to do. As a result, the expected linked event was not
triggered after and the test failed.

This is due to the fact the token given in argument to the application
was parsed as an integer with atoi(): in a 32-bit arch, if the number
was bigger than INT_MAX, 2147483647 was used instead.

This can simply be fixed by using strtoul() instead of atoi().

The errors have been seen "by chance" when manually looking at the
results from LKFT.

Matthieu Baerts 6c8880fcaa selftests: mptcp: depend on SYN_COOKIES
MPTCP selftests are using TCP SYN Cookies for quite a while now, since
v5.9.

Some CIs don't have this config option enabled and this is causing
issues in the tests:

  # ns1 MPTCP -> ns1 (10.0.1.1:10000      ) MPTCP     (duration   167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
  # [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected

There is no impact in the results but the test is not doing what it is
supposed to do.

Jason A. Donenfeld f58d0a9b4c wireguard: netlink: send staged packets when setting initial private key
Packets bound for peers can queue up prior to the device private key
being set. For example, if persistent keepalive is set, a packet is
queued up to be sent as soon as the device comes up. However, if the
private key hasn't been set yet, the handshake message never sends, and
no timer is armed to retry, since that would be pointless.

But, if a user later sets a private key, the expectation is that those
queued packets, such as a persistent keepalive, are actually sent. So
adjust the configuration logic to account for this edge case, and add a
test case to make sure this works.

Maxim noticed this with a wg-quick(8) config to the tune of:

    [Interface]
    PostUp = wg set %i private-key somefile

    [Peer]
    PublicKey = ...
    Endpoint = ...
    PersistentKeepalive = 25

Here, the private key gets set after the device comes up using a PostUp
script, triggering the bug.

Pull CXL updates from Dan Williams:
 "The highlights in terms of new functionality are support for the
  standard CXL Performance Monitor definition that appeared in CXL 3.0,
  support for device sanitization (wiping all data from a device),
  secure-erase (re-keying encryption of user data), and support for
  firmware update. The firmware update support is notable as it reuses
  the simple sysfs_upload interface to just cat(1) a blob to a sysfs
  file and pipe that to the device.

  Additionally there are a substantial number of cleanups and
  reorganizations to get ready for RCH error handling (RCH == Restricted
  CXL Host == current shipping hardware generation / pre CXL-2.0
  topologies) and type-2 (accelerator / vendor specific) devices.

  For vendor specific devices they implement a subset of what the
  generic type-3 (generic memory expander) driver expects. As a result
  the rework decouples optional infrastructure from the core driver
  context.

  For RCH topologies, where the specification working group did not want
  to confuse pre-CXL-aware operating systems, many of the standard
  registers are hidden which makes support standard bus features like
  AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
  the driver to help the PCI-AER core. Bjorn is on board with this
  direction but a late regression disocvery means the completion of this
  functionality needs to cook a bit longer, so it is code
  reorganizations only for now.

  Summary:

   - Add infrastructure for supporting background commands along with
     support for device sanitization and firmware update

   - Introduce a CXL performance monitoring unit driver based on the
     common definition in the specification.

   - Land some preparatory cleanup and refactoring for the anticipated

 "This is mostly small cleanups and fixes, with the biggest change being
  the change to the DAX fault handler allowing it to return
  VM_FAULT_HWPOISON.

  Summary:

   - DAX fixes and cleanups including a use after free, extra
     references, and device unregistration, and a redundant variable.

   - Allow the DAX fault handler to return VM_FAULT_HWPOISON

   - A few libnvdimm cleanups such as making some functions and
     variables static where sufficient.

   - Add a few missing prototypes for wrapped functions in
     tools/testing/nvdimm"

selftests: Test RISC-V Vector's first-use handler
This add a test to check if the kernel zero-initializes all V registers
after the first-use trap handler returns.

If V registers are not zero-initialized, then the test should fail one
out of several runs:

```
 root@sifive-fpga:~# ./v_initval_nolibc
 # vl = 256
 not ok 1 detect stale values on v-regesters
 0 0 0 0 0 0 0 0   0 0 0 0 0 0 0 0
 0 4c 41 4e 47 3d 43 0   50 41 54 48 3d 2f 75 73

 ff ff 81 0 0 0 0 0   0 0 0 0 0 0 0 0
```

Otherwise, the test passes without errors each run.

Linus Torvalds d2a6fd45c5 Probes updates for v6.5:
- fprobe: Pass return address to the fprobe entry/exit callbacks so that
   the callbacks don't need to analyze pt_regs/stack to find the function
   return address.
 
 - kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
   flags so that those are not set at once.
 
 - fprobe events:
  . Add a new fprobe events for tracing arbitrary function entry and
    exit as a trace event.
  . Add a new tracepoint events for tracing raw tracepoint as a trace
    event. This allows user to trace non user-exposed tracepoints.
  . Move eprobe's event parser code into probe event common file.
  . Introduce BTF (BPF type format) support to kernel probe (kprobe,
    fprobe and tracepoint probe) events so that user can specify traced
    function arguments by name. This also applies the type of argument
    when fetching the argument.
  . Introduce '$arg*' wildcard support if BTF is available. This expands
    the '$arg*' meta argument to all function argument automatically.
  . Check the return value types by BTF. If the function returns 'void',
    '$retval' is rejected.
  . Add some selftest script for fprobe events, tracepoint events and
    BTF support.
  . Update documentation about the fprobe events.
  . Some fixes for above features, document and selftests.
 
 - selftests for ftrace (except for new fprobe events):
  . Add a test case for multiple consecutive probes in a function which
    checks if ftrace based kprobe, optimized kprobe and normal kprobe
    can be defined in the same target function.
  . Add a test case for optimized probe, which checks whether kprobe
    can be optimized or not.

Linus Torvalds cccf0c2ee5 Tracing updates for 6.5:
- Add new feature to have function graph tracer record the return value.
   Adds a new option: funcgraph-retval ; when set, will show the return
   value of a function in the function graph tracer.
 
 - Also add the option: funcgraph-retval-hex where if it is not set, and
   the return value is an error code, then it will return the decimal of
   the error code, otherwise it still reports the hex value.
 
 - Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
   That when a application opens it, it becomes the task that the timer lat
   tracer traces. The application can also read this file to find out how
   it's being interrupted.
 
 - Add the file /sys/kernel/tracing/available_filter_functions_addrs
   that works just the same as available_filter_functions but also shows
   the addresses of the functions like kallsyms, except that it gives the
   address of where the fentry/mcount jump/nop is. This is used by BPF to
   make it easier to attach BPF programs to ftrace hooks.
 
 - Replace strlcpy with strscpy in the tracing boot code.

Linus Torvalds 3ad7b12c72 tracing: Fix user event write on buffer disabled
The user events write currently returns the size of what was suppose to be
 written when tracing is disabled and nothing was written. Instead, behave like
 trace_marker and return -EBADF, as that is what is returned if a file is opened
 for read only, and a write is performed on it. Writing to the buffer
 that is disabled is like trying to write to a file opened for read
 only, as the buffer still can be read, but just not written to.
 
 This also includes test cases for this use case

Linus Torvalds f8824e151f sound updates for 6.5-rc1
Lots of changes as usual, but the only significant stuff in ALSA core
 part is the MIDI 2.0 support, while ASoC core kept receiving the code
 refactoring.  The majority of changes are seen rather in device
 drivers, and quite a few new drivers can be found there.
 
 Here we go, some highlights:
 
 ALSA and ASoC Core:
 - Support of MIDI 2.0 devices: rawmidi and sequencer API have been
   extended for the support of the new UMP (Universal MIDI Packet)
   protocol, USB audio driver got the USB MIDI 2.0 interface support
 - Continued refactoring around ASoC DAI links and the ordering of
   trigger callbacks
 - PCM ABI extension for better drain support
 
 ASoC Drivers:
 - Conversions of many drivers to use maple tree based caches
 - Everlasting improvement works on ASoC Intel drivers
 - Compressed audio support for Qualcomm
 - Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon,
   Ingenic X1000, Intel systems with various CODECs, Loongson
   platforms, Maxim MAX98388, Mediatek MT8188, Nuvoton NAU8825C, NXP
   platforms with NAU8822, Qualcomm WSA884x, StarFive JH7110, Texas
   Instruments TAS2781
 
 HD-audio:
 - Quirks for HP and ASUS machines
 - CS35L41 HD-audio codec fixes
 - Loongson HD-audio support
 
 Misc:
 - A new virtual PCM test driver for kselftests
 - Continued refactoring and improvements on the legacy emu10k1 driver

 "We have two new drivers, some improvements to the core code, lots of

  There's nothing controversial in here and almost everything has been

  regressions.

Linus Torvalds 3a8a670eee Networking changes for 6.5.
Core
 ----
 
  - Rework the sendpage & splice implementations. Instead of feeding
    data into sockets page by page extend sendmsg handlers to support
    taking a reference on the data, controlled by a new flag called
    MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
    to invoke an additional callback instead of trying to predict what
    the right combination of MORE/NOTLAST flags is.
    Remove the MSG_SENDPAGE_NOTLAST flag completely.
 
  - Implement SCM_PIDFD, a new type of CMSG type analogous to
    SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
 
  - Enable socket busy polling with CONFIG_RT.
 
  - Improve reliability and efficiency of reporting for ref_tracker.
 
  - Auto-generate a user space C library for various Netlink families.
 
 Protocols
 ---------
 
  - Allow TCP to shrink the advertised window when necessary, prevent
    sk_rcvbuf auto-tuning from growing the window all the way up to
    tcp_rmem[2].
 
  - Use per-VMA locking for "page-flipping" TCP receive zerocopy.
 
  - Prepare TCP for device-to-device data transfers, by making sure
    that payloads are always attached to skbs as page frags.
 
  - Make the backoff time for the first N TCP SYN retransmissions
    linear. Exponential backoff is unnecessarily conservative.
 
  - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
 
  - Avoid waking up applications using TLS sockets until we have
    a full record.
 
  - Allow using kernel memory for protocol ioctl callbacks, paving
    the way to issuing ioctls over io_uring.
 
  - Add nolocalbypass option to VxLAN, forcing packets to be fully
    encapsulated even if they are destined for a local IP address.
 
  - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
    in-kernel ECMP implementation (e.g. Open vSwitch) select the same
    link for all packets. Support L4 symmetric hashing in Open vSwitch.
 
  - PPPoE: make number of hash bits configurable.
 
  - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
    (ipconfig).
 
  - Add layer 2 miss indication and filtering, allowing higher layers
    (e.g. ACL filters) to make forwarding decisions based on whether
    packet matched forwarding state in lower devices (bridge).
 
  - Support matching on Connectivity Fault Management (CFM) packets.
 
  - Hide the "link becomes ready" IPv6 messages by demoting their
    printk level to debug.
 
  - HSR: don't enable promiscuous mode if device offloads the proto.
 
  - Support active scanning in IEEE 802.15.4.
 
  - Continue work on Multi-Link Operation for WiFi 7.
 
 BPF
 ---
 
  - Add precision propagation for subprogs and callbacks. This allows
    maintaining verification efficiency when subprograms are used,
    or in fact passing the verifier at all for complex programs,
    especially those using open-coded iterators.
 
  - Improve BPF's {g,s}setsockopt() length handling. Previously BPF
    assumed the length is always equal to the amount of written data.
    But some protos allow passing a NULL buffer to discover what
    the output buffer *should* be, without writing anything.
 
  - Accept dynptr memory as memory arguments passed to helpers.
 
  - Add routing table ID to bpf_fib_lookup BPF helper.
 
  - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
 
  - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
    maps as read-only).
 
  - Show target_{obj,btf}_id in tracing link fdinfo.
 
  - Addition of several new kfuncs (most of the names are self-explanatory):
    - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
      bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
      and bpf_dynptr_clone().
    - bpf_task_under_cgroup()
    - bpf_sock_destroy() - force closing sockets
    - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
 
 Netfilter
 ---------
 
  - Relax set/map validation checks in nf_tables. Allow checking
    presence of an entry in a map without using the value.
 
  - Increase ip_vs_conn_tab_bits range for 64BIT builds.
 
  - Allow updating size of a set.
 
  - Improve NAT tuple selection when connection is closing.
 
 Driver API
 ----------
 
  - Integrate netdev with LED subsystem, to allow configuring HW
    "offloaded" blinking of LEDs based on link state and activity
    (i.e. packets coming in and out).
 
  - Support configuring rate selection pins of SFP modules.
 
  - Factor Clause 73 auto-negotiation code out of the drivers, provide
    common helper routines.
 
  - Add more fool-proof helpers for managing lifetime of MDIO devices
    associated with the PCS layer.
 
  - Allow drivers to report advanced statistics related to Time Aware
    scheduler offload (taprio).
 
  - Allow opting out of VF statistics in link dump, to allow more VFs
    to fit into the message.
 
  - Split devlink instance and devlink port operations.

Pull networking changes from Jakub Kicinski:
 "WiFi 7 and sendpage changes are the biggest pieces of work for this
  release. The latter will definitely require fixes but I think that we
  got it to a reasonable point.

  Core:

   - Rework the sendpage & splice implementations

     Instead of feeding data into sockets page by page extend sendmsg
     handlers to support taking a reference on the data, controlled by a
     new flag called MSG_SPLICE_PAGES

     Rework the handling of unexpected-end-of-file to invoke an
     additional callback instead of trying to predict what the right
     combination of MORE/NOTLAST flags is

     Remove the MSG_SENDPAGE_NOTLAST flag completely

   - Implement SCM_PIDFD, a new type of CMSG type analogous to
     SCM_CREDENTIALS, but it contains pidfd instead of plain pid

   - Enable socket busy polling with CONFIG_RT

   - Improve reliability and efficiency of reporting for ref_tracker

   - Auto-generate a user space C library for various Netlink families

  Protocols:

   - Allow TCP to shrink the advertised window when necessary, prevent
     sk_rcvbuf auto-tuning from growing the window all the way up to
     tcp_rmem[2]

   - Use per-VMA locking for "page-flipping" TCP receive zerocopy

   - Prepare TCP for device-to-device data transfers, by making sure
     that payloads are always attached to skbs as page frags

   - Make the backoff time for the first N TCP SYN retransmissions
     linear. Exponential backoff is unnecessarily conservative

   - Create a new MPTCP getsockopt to retrieve all info
     (MPTCP_FULL_INFO)

   - Avoid waking up applications using TLS sockets until we have a full
     record

   - Allow using kernel memory for protocol ioctl callbacks, paving the
     way to issuing ioctls over io_uring

   - Add nolocalbypass option to VxLAN, forcing packets to be fully
     encapsulated even if they are destined for a local IP address

     assumed the length is always equal to the amount of written data.
     But some protos allow passing a NULL buffer to discover what the
     output buffer *should* be, without writing anything

   - Accept dynptr memory as memory arguments passed to helpers

   - Add routing table ID to bpf_fib_lookup BPF helper

   - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands

   - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
     maps as read-only)

   - Show target_{obj,btf}_id in tracing link fdinfo

   - Addition of several new kfuncs (most of the names are
     self-explanatory):
      - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
        bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
        and bpf_dynptr_clone().
      - bpf_task_under_cgroup()
      - bpf_sock_destroy() - force closing sockets
      - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs

  Netfilter:

   - Relax set/map validation checks in nf_tables. Allow checking
     presence of an entry in a map without using the value

   - Increase ip_vs_conn_tab_bits range for 64BIT builds

Linus Torvalds 6a8cbd9253 v6.5-rc1-sysctl-next
The changes queued up for v6.5-rc1 for sysctl are in line with
 prior efforts to stop usage of deprecated routines which incur
 recursion and also make it hard to remove the empty array element
 in each sysctl array declaration. The most difficult user to modify
 was parport which required a bit of re-thinking of how to declare shared
 sysctls there, Joel Granados has stepped up to the plate to do most of
 this work and eventual removal of register_sysctl_table(). That work
 ended up saving us about 1465 bytes according to bloat-o-meter. Since
 we gained a few bloat-o-meter karma points I moved two rather small
 sysctl arrays from kernel/sysctl.c leaving us only two more sysctl
 arrays to move left.
 
 Most changes have been tested on linux-next for about a month. The last
 straggler patches are a minor parport fix, changes to the sysctl
 kernel selftest so to verify correctness and prevent regressions for
 the future change he made to provide an alternative solution for the
 special sysctl mount point target which was using the now deprecated
 sysctl child element.
 
 This is all prep work to now finally be able to remove the empty
 array element in all sysctl declarations / registrations which is
 expected to save us a bit of bytes all over the kernel. That work
 will be tested early after v6.5-rc1 is out.

The changes queued up for v6.5-rc1 for modules are pretty tame, mostly
 code removal of moving of code. Only two minor functional changes are
 made, the only one which stands out is Sebastian Andrzej Siewior's
 simplification of module reference counting by removing preempt_disable()
 and that has been tested on linux-next for well over a month without
 no regressions. I'm now, I guess, also a kitchen sink for some kallsyms
 changes.

[ There was a mis-communication about the concurrent module load changes
  that I had expected to come through Luis despite me authoring the
  patch. So some of the module updates were left hanging in the email
  ether, and I just committed them separately.

  It's my bad - I should have made it more clear that I expected my
  own patches to come through the module tree too. Now they missed
  linux-next, but hopefully that won't cause any issues    - Linus ]

Linus Torvalds 6e17c6de3d - Yosry Ahmed brought back some cgroup v1 stats in OOM logs.
- Yosry has also eliminated cgroup's atomic rstat flushing.
 
 - Nhat Pham adds the new cachestat() syscall.  It provides userspace
   with the ability to query pagecache status - a similar concept to
   mincore() but more powerful and with improved usability.
 
 - Mel Gorman provides more optimizations for compaction, reducing the
   prevalence of page rescanning.
 
 - Lorenzo Stoakes has done some maintanance work on the get_user_pages()
   interface.
 
 - Liam Howlett continues with cleanups and maintenance work to the maple
   tree code.  Peng Zhang also does some work on maple tree.
 
 - Johannes Weiner has done some cleanup work on the compaction code.
 
 - David Hildenbrand has contributed additional selftests for
   get_user_pages().
 
 - Thomas Gleixner has contributed some maintenance and optimization work
   for the vmalloc code.
 
 - Baolin Wang has provided some compaction cleanups,
 
 - SeongJae Park continues maintenance work on the DAMON code.
 
 - Huang Ying has done some maintenance on the swap code's usage of
   device refcounting.
 
 - Christoph Hellwig has some cleanups for the filemap/directio code.
 
 - Ryan Roberts provides two patch series which yield some
   rationalization of the kernel's access to pte entries - use the provided
   APIs rather than open-coding accesses.
 
 - Lorenzo Stoakes has some fixes to the interaction between pagecache
   and directio access to file mappings.
 
 - John Hubbard has a series of fixes to the MM selftesting code.
 
 - ZhangPeng continues the folio conversion campaign.
 
 - Hugh Dickins has been working on the pagetable handling code, mainly
   with a view to reducing the load on the mmap_lock.
 
 - Catalin Marinas has reduced the arm64 kmalloc() minimum alignment from
   128 to 8.
 
 - Domenico Cerasuolo has improved the zswap reclaim mechanism by
   reorganizing the LRU management.
 
 - Matthew Wilcox provides some fixups to make gfs2 work better with the
   buffer_head code.

Merge tag 'hardening-v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull hardening updates from Kees Cook:
 "There are three areas of note:

  A bunch of strlcpy()->strscpy() conversions ended up living in my tree
  since they were either Acked by maintainers for me to carry, or got
  ignored for multiple weeks (and were trivial changes).

  The compiler option '-fstrict-flex-arrays=3' has been enabled
  globally, and has been in -next for the entire devel cycle. This
  changes compiler diagnostics (though mainly just -Warray-bounds which
  is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
  coverage. In other words, there are no new restrictions, just
  potentially new warnings. Any new FORTIFY warnings we've seen have
  been fixed (usually in their respective subsystem trees). For more
  details, see commit df8fc4e934.

  The under-development compiler attribute __counted_by has been added
  so that we can start annotating flexible array members with their
  associated structure member that tracks the count of flexible array
  elements at run-time. It is possible (likely?) that the exact syntax
  of the attribute will change before it is finalized, but GCC and Clang
  are working together to sort it out. Any changes can be made to the
  macro while we continue to add annotations.

  As an example of that last case, I have a treewide commit waiting with
  such annotations found via Coccinelle:

    https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b

  Also see commit dd06e72e68 for more details.

  This also extends Landlock's tests with 6 pseudo filesystems,

Dan Williams aeaefabc59 Merge branch 'for-6.5/cxl-type-2' into for-6.5/cxl
Pick up the driver cleanups identified in preparation for CXL "type-2"
(accelerator) device support. The major change here from a conflict
generation perspective is the split of 'struct cxl_memdev_state' from
the core 'struct cxl_dev_state'. Since an accelerator may not care about
all the optional features that are standard on a CXL "type-3" (host-only
memory expander) device.

A silent conflict also occurs with the move of the endpoint port to be a
formal property of a 'struct cxl_memdev' rather than drvdata.

sanitization were developed in parallel from the common
background-command baseline, resolve some minor context conflicts.

Dan Williams dcfb70610d Merge branch 'for-6.5/cxl-background' into for-6.5/cxl
Pick up the sanitization work and the infrastructure for other
background commands for 6.5. Sanitization has a different completion
path than typical background commands so it was important to have both
thought out and implemented before either went upstream.

Vishal Verma f6448cb5f2 tools/testing/cxl: add firmware update emulation to CXL memdevs
Add emulation for the 'Get FW Info', 'Transfer FW', and 'Activate FW'
CXL mailbox commands to the cxl_test emulated memdevs to enable
end-to-end unit testing of a firmware update flow. For now, only
advertise an 'offline activation' capability as that is all the CXL
memdev driver currently implements.

Add some canned values for the serial number fields, and create a
platform device sysfs knob to calculate the sha256sum of the firmware
image that was received, so a unit test can compare it with the original
file that was uploaded.

Dan Williams 8f0220af58 Revert "cxl/port: Enable the HDM decoder capability for switch ports"
commit eb0764b822 ("cxl/port: Enable the HDM decoder capability for switch ports")

...was added on the observation of CXL memory not being accessible after
setting up a region on a "cold-plugged" device. A "cold-plugged" CXL
device is one that was not present at boot, so platform-firmware/BIOS
has no chance to set it up.

While it is true that the debug found the enable bit clear in the
host-bridge's instance of the global control register (CXL 3.0
8.2.4.19.2 CXL HDM Decoder Global Control Register), that bit is
described as:

"This bit is only applicable to CXL.mem devices and shall
return 0 on CXL Host Bridges and Upstream Switch Ports."

So it is meant to be zero, and further testing confirmed that this "fix"
had no effect on the failure. Revert it, and be more vigilant about
proposed fixes in the future. Since the original copied stable@, flag
this revert for stable@ as well.

In preparation for support for HDM-D and HDM-DB configuration
(device-memory, and device-memory with back-invalidate). Rename the current
type designators to use HOSTONLYMEM and DEVMEM as a suffix.

HDM-DB can be supported by devices that are not accelerators, so DEVMEM is
a more generic term for that case.

Fixup one location where this type value was open coded.

Dan Williams 59f8d15107 cxl/mbox: Move mailbox related driver state to its own data structure
'struct cxl_dev_state' makes too many assumptions about the capabilities
of a CXL device. In particular it assumes a CXL device has a mailbox and
all of the infrastructure and state that comes along with that.

In preparation for supporting accelerator / Type-2 devices that may not
have a mailbox and in general maintain a minimal core context structure,
make mailbox functionality a super-set of  'struct cxl_dev_state' with
'struct cxl_memdev_state'.

With this reorganization it allows for CXL devices that support HDM
decoder mapping, but not other general-expander / Type-3 capabilities,
to only enable that subset without the rest of the mailbox
infrastructure coming along for the ride.

Dan Williams 0619337856 cxl/rch: Prepare for caching the MMIO mapped PCIe AER capability
Prepare cxl_probe_rcrb() for retrieving more than just the component
register block. The RCH AER handling code wants to get back to the AER
capability that happens to be MMIO mapped rather then configuration
cycles.

Move RCRB specific downstream port data, like the RCRB base and the
AER capability offset, into its own data structure ('struct
cxl_rcrb_info') for cxl_probe_rcrb() to fill. Extend 'struct
cxl_dport' to include a 'struct cxl_rcrb_info' attribute.

This centralizes all RCRB scanning in one routine.

Robert Richter eb4663b07e cxl/acpi: Probe RCRB later during RCH downstream port creation
The RCRB is extracted already during ACPI CEDT table parsing while the
data of this is needed not earlier than dport creation. This
implementation comes with drawbacks: During ACPI table scan there is
already MMIO access including mapping and unmapping, but only ACPI
data should be collected here. The collected data must be transferred
through a couple of interfaces until it is finally consumed when
creating the dport. This causes complex data structures and function
interfaces. Additionally, RCRB parsing will be extended to also
extract AER data, it would be much easier do this at a later point
during port and dport creation when the data structures are available
to hold that data.

To simplify all that, probe the RCRB at a later point during RCH
downstream port creation. Change ACPI table parser to only extract the
base address of either the component registers or the RCRB. Parse and
extract the RCRB in devm_cxl_add_rch_dport().

This is in preparation to centralize all RCRB scanning.

Geliang Tang 1534f87ee0 selftests: mptcp: drop sflags parameter
run_tests() accepts too many optional parameters. Before this modification,
it was required to set all of then when only the last one had to be
changed. That's not clear to see all these 0 and it makes the maintenance
harder:

      run_tests $ns1 $ns2 10.0.1.1 1 2 3 slow

Instead, the parameter can be set as an env var with a limited scope:

      foo=1 bar=2 next=3 \
            run_tests $ns1 $ns2 10.0.1.1 slow

This patch switches to key/value "sflags=*" instead of positional parameter
sflags of do_transfer() and run_tests().
