527eff227d - In the series "treewide: Refactor heap related implementation", 
Kuan-Wei Chiu has significantly reworked the min_heap library code and
   has taught bcachefs to use the new more generic implementation.
 
 - Yury Norov's series "Cleanup cpumask.h inclusion in core headers"
   reworks the cpumask and nodemask headers to make things generally more
   rational.
 
 - Kuan-Wei Chiu has sent along some maintenance work against our sorting
   library code in the series "lib/sort: Optimizations and cleanups".
 
 - More library maintainance work from Christophe Jaillet in the series
   "Remove usage of the deprecated ida_simple_xx() API".
 
 - Ryusuke Konishi continues with the nilfs2 fixes and clanups in the
   series "nilfs2: eliminate the call to inode_attach_wb()".
 
 - Kuan-Ying Lee has some fixes to the gdb scripts in the series "Fix GDB
   command error".
 
 - Plus the usual shower of singleton patches all over the place.  Please
   see the relevant changelogs for details.

Pull slab updates from Vlastimil Babka:
 "The most prominent change this time is the kmem_buckets based
  hardening of kmalloc() allocations from Kees Cook.

  We have also extended the kmalloc() alignment guarantees for
  non-power-of-two sizes in a way that benefits rust.

  The rest are various cleanups and non-critical fixups.

   - Dedicated bucket allocator (Kees Cook)

     This series [1] enhances the probabilistic defense against heap
     spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year.

     kmalloc() users that are known to be useful for exploits can get
     completely separate set of kmalloc caches that can't be shared with
     other users. The first converted users are alloc_msg() and
     memdup_user().

     The hardening is enabled by CONFIG_SLAB_BUCKETS.

   - Extended kmalloc() alignment guarantees (Vlastimil Babka)

     For years now we have guaranteed natural alignment for power-of-two
     allocations, but nothing was defined for other sizes (in practice,
     we have two such buckets, kmalloc-96 and kmalloc-192).

     To avoid unnecessary padding in the rust layer due to its alignment
     rules, extend the guarantee so that the alignment is at least the
     largest power-of-two divisor of the requested size.

     This fits what rust needs, is a superset of the existing
     power-of-two guarantee, and does not in practice change the layout
     (and thus does not add overhead due to padding) of the kmalloc-96
     and kmalloc-192 caches, unless slab debugging is enabled for them.

   - Cleanups and non-critical fixups (Chengming Zhou, Suren
     Baghdasaryan, Matthew Willcox, Alex Shi, and Vlastimil Babka)

     Various tweaks related to the new alloc profiling code, folio
     conversion, debugging and more leftovers after SLAB"

49208b6758 kbuild: fix rebuild of generic syscall headers 
Commit fbb5c0606f ("kbuild: add syscall table generation to
scripts/Makefile.asm-headers") started to generate syscall headers
for architectures using generic syscalls.

However, these headers are always rebuilt using GNU Make 4.4.1 or newer.

When using GNU Make 4.4 or older, these headers are not rebuilt when the
command to generate them is changed, despite the use of the if_changed
macro.

scripts/Makefile.asm-headers now uses FORCE, but it is not marked as
.PHONY. To handle the command line change correctly, .*.cmd files must
be included.

51835949dd Networking changes for 6.11. Not much excitement - a handful of large 
patchsets (devmem among them) did not make it in time.
 
 Core & protocols
 ----------------
 
  - Use local_lock in addition to local_bh_disable() to protect per-CPU
    resources in networking, a step closer for local_bh_disable() not
    to act as a big lock on PREEMPT_RT.
 
  - Use flex array for netdevice priv area, ensure its cache alignment.
 
  - Add a sysctl knob to allow user to specify a default rto_min at socket
    init time. Bit of a big hammer but multiple companies were
    independently carrying such patch downstream so clearly it's useful.
 
  - Support scheduling transmission of packets based on CLOCK_TAI.
 
  - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
    using cpusets.
 
  - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
 
  - Allow configuration of multipath hash seed, to both allow synchronizing
    hashing of two routers, and preventing partial accidental sync.
 
  - Improve TCP compliance with RFC 9293 for simultaneous connect().
 
  - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
    IKE daemon had to do this before, but the kernel can better keep
    track of it.
 
  - Support sending supervision HSR frames with MAC addresses stored in
    ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
 
  - Introduce IPPROTO_SMC for selecting SMC when socket is created.
 
  - Allow UDP GSO transmit from devices with no checksum offload.
 
  - openvswitch: add packet sampling via psample, separating the sampled
    traffic from "upcall" packets sent to user space for forwarding.
 
  - nf_tables: shrink memory consumption for transaction objects.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Power Sequencing subsystem (used by Qualcomm Bluetooth driver
    for QCA6390).
 
  - Add IRQ information in sysfs for auxiliary bus.
 
  - Introduce guard definition for local_lock.
 
  - Add aligned flavor of __cacheline_group_{begin, end}() markings for
    grouping fields in structures.
 
 BPF
 ---
 
  - Notify user space (via epoll) when a struct_ops object is getting
    detached/unregistered.
 
  - Add new kfuncs for a generic, open-coded bits iterator.
 
  - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
    bpf_list_head.
 
  - Support resilient split BTF which cuts down on duplication and makes
    BTF as compact as possible WRT BTF from modules.
 
  - Add support for dumping kfunc prototypes from BTF which enables both
    detecting as well as dumping compilable prototypes for kfuncs.
 
  - riscv64 BPF JIT improvements in particular to add 12-argument support
    for BPF trampolines and to utilize bpf_prog_pack for the latter.
 
  - Add the capability to offload the netfilter flowtable in XDP layer
    through kfuncs.
 
 Driver API
 ----------
 
  - Allow users to configure IRQ tresholds between which automatic IRQ
    moderation can choose.
 
  - Expand Power Sourcing (PoE) status with power, class and failure
    reason. Support setting power limits.
 
  - Track additional RSS contexts in the core, make sure configuration
    changes don't break them.
 
  - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
    data paths.
 
  - Support updating firmware on SFP modules.
 
 Tests and tooling
 -----------------
 
  - mptcp: use net/lib.sh to manage netns.
 
  - TCP-AO and TCP-MD5: replace debug prints used by tests with
    tracepoints.
 
  - openvswitch: make test self-contained (don't depend on OvS CLI tools).

d80f2996b8 asm-generic updates for 6.11 
Most of this is part of my ongoing work to clean up the system call
 tables. In this bit, all of the newer architectures are converted to
 use the machine readable syscall.tbl format instead in place of complex
 macros in include/uapi/asm-generic/unistd.h.
 
 This follows an earlier series that fixed various API mismatches
 and in turn is used as the base for planned simplifications.
 
 The other two patches are dead code removal and a warning fix.

There's one new feature here, a regmap_multi_reg_read() matching the
 existing write function which has some IIO users coming.  This allows
 atomic reads from multiple registers without the need to wrap a higher
 level lock in the client driver just for regmap (which already has locks
 anyway).  We also have one fix for the KUnit tests, and a bunch of
 cleanups.

e3286434d2 kbuild: rpm-pkg: avoid the warnings with dtb's listed twice 
After 8d1001f7bd (kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n),
the following warning "warning: File listed twice: *.dtb" is appearing for
every dtb file that is included.
The reason is that the commented commit already adds the folder
/lib/modules/%{KERNELRELEASE} in kernel.list file so the folder
/lib/modules/%{KERNELRELEASE}/dtb is no longer necessary, just remove it.

9852f47ac7 kbuild: Make ld-version.sh more robust against version string changes 
After [1] in upstream LLVM, ld.lld's version output became slightly
different when the cmake configuration option LLVM_APPEND_VC_REV is
disabled.

Before:

  Debian LLD 19.0.0 (compatible with GNU linkers)

After:

  Debian LLD 19.0.0, compatible with GNU linkers

This results in ld-version.sh failing with

  scripts/ld-version.sh: 18: arithmetic expression: expecting EOF: "10000 * 19 + 100 * 0 + 0,"

because the trailing comma is included in the patch level part of the
expression. While [1] has been partially reverted in [2] to avoid this
breakage (as it impacts the configuration stage and it is present in all
LTS branches), it would be good to make ld-version.sh more robust
against such miniscule changes like this one.

Use POSIX shell parameter expansion [3] to remove the largest suffix
after just numbers and periods, replacing of the current removal of
everything after a hyphen. ld-version.sh continues to work for a number
of distributions (Arch Linux, Debian, and Fedora) and the kernel.org
toolchains and no longer errors on a version of ld.lld with [1].

73db3abdca init/modpost: conditionally check section mismatch to __meminit* 
This reverts commit eb8f689046 ("Use separate sections for __dev/
_cpu/__mem code/data").

Check section mismatch to __meminit* only when CONFIG_MEMORY_HOTPLUG=n.

With this change, the linker script and modpost become simpler, and we
can get rid of the __ref annotations from the memory hotplug code.

3db80c999d riscv: convert to generic syscall table 
The uapi/asm/unistd_{32,64}.h and asm/syscall_table_{32,64}.h headers can
now be generated from scripts/syscall.tbl, which makes this consistent
with the other architectures that have their own syscall.tbl.

riscv has two extra system call that gets added to scripts/syscall.tbl.

The newstat and rlimit entries in the syscall_abis_64 line are for system
calls that were part of the generic ABI when riscv64 got added but are
no longer enabled by default for new architectures. Both riscv32 and
riscv64 also implement memfd_secret, which is optional for all
architectures.

Unlike all the other 32-bit architectures, the time32 and stat64
sets of syscalls are not enabled on riscv32.

Both the user visible side of asm/unistd.h and the internal syscall
table in the kernel should have the same effective contents after this.

When asm/syscalls.h is included in kernel/fork.c for the purpose of
type checking, the redirection macros cause problems.  Move these so

fbb5c0606f kbuild: add syscall table generation to scripts/Makefile.asm-headers 
There are 11 copies of arch/*/kernel/syscalls/Makefile that all implement
the same basic logic in a somewhat awkward way.

I tried out various ways of unifying the existing copies and ended up
with something that hooks into the logic for generating the redirections
to asm-generic headers. This gives a nicer syntax of being able to list
the generated files in $(syscall-y) inside of arch/*/include/asm/Kbuild
instead of both $(generated-y) in that place and also in another
Makefile.

The configuration for which syscall.tbl file to use and which ABIs to
enable is now done in arch/*/kernel/Makefile.syscalls. I have done
patches for all architectures and made sure that the new generic
rules implement a superset of all the architecture specific corner
cases.

ince the header file is not specific to asm-generic/*.h redirects
now, I ended up renaming the file to scripts/Makefile.asm-headers.

In order to integrate the system call header generation with generating
the asm-generic wrappers, restrict the generated headers to those that
actually exist in include/asm-generic/.

The path is already known, so add these as a dependency.

The asm-generic/bugs.h header was removed in commit 61235b24b9 ("init:

====================
pull-request: bpf-next 2024-07-08

The following pull-request contains BPF updates for your *net-next* tree.

We've added 102 non-merge commits during the last 28 day(s) which contain
a total of 127 files changed, 4606 insertions(+), 980 deletions(-).

The main changes are:

1) Support resilient split BTF which cuts down on duplication and makes BTF
   as compact as possible wrt BTF from modules, from Alan Maguire & Eduard Zingerman.

2) Add support for dumping kfunc prototypes from BTF which enables both detecting
   as well as dumping compilable prototypes for kfuncs, from Daniel Xu.

3) Batch of s390x BPF JIT improvements to add support for BPF arena and to implement
   support for BPF exceptions, from Ilya Leoshkevich.

4) Batch of riscv64 BPF JIT improvements in particular to add 12-argument support
   for BPF trampolines and to utilize bpf_prog_pack for the latter, from Pu Lehui.

5) Extend BPF test infrastructure to add a CHECKSUM_COMPLETE validation option
   for skbs and add coverage along with it, from Vadim Fedorenko.

6) Inline bpf_get_current_task/_btf() helpers in the arm64 BPF JIT which gives
   a small 1% performance improvement in micro-benchmarks, from Puranjay Mohan.

7) Extend the BPF verifier to track the delta between linked registers in order
   to better deal with recent LLVM code optimizations, from Alexei Starovoitov.

8) Fix bpf_wq_set_callback_impl() kfunc signature where the third argument should
   have been a pointer to the map value, from Benjamin Tissoires.

9) Extend BPF selftests to add regular expression support for test output matching
   and adjust some of the selftest when compiled under gcc, from Cupertino Miranda.

10) Simplify task_file_seq_get_next() and remove an unnecessary loop which always
    iterates exactly once anyway, from Dan Carpenter.

11) Add the capability to offload the netfilter flowtable in XDP layer through
    kfuncs, from Florian Westphal & Lorenzo Bianconi.

12) Various cleanups in networking helpers in BPF selftests to shave off a few
    lines of open-coded functions on client/server handling, from Geliang Tang.

13) Properly propagate prog->aux->tail_call_reachable out of BPF verifier, so
    that x86 JIT does not need to implement detection, from Leon Hwang.

14) Fix BPF verifier to add a missing check_func_arg_reg_off() to prevent an
    out-of-bounds memory access for dynpointers, from Matt Bobrowski.

15) Fix bpf_session_cookie() kfunc to return __u64 instead of long pointer as
    it might lead to problems on 32-bit archs, from Jiri Olsa.

16) Enhance traffic validation and dynamic batch size support in xsk selftests,
    from Tushar Vyavahare.

18c18b1ff6 gcc-plugins: Remove duplicate included header file stringpool.h 
The header file stringpool.h is included for GCC version >= 8 and then
again for all versions.

Since the header file stringpool.h was added in GCC 4.9 and the kernel
currently requires GCC 5.1 as a minimum, remove the conditional include.

Including the header file only once removes the following warning
reported by make includecheck:

  stringpool.h is included more than once

However, it's important to include stringpool.h before attribs.h
because attribs.h uses some of its functions.

Compile-tested with GCC 14.

4fe53bf2ba syscalls: add generic scripts/syscall.tbl 
The asm-generic/unistd.h header still follows the old style of defining
system call numbers and the table. Most architectures got the new
syscall.tbl format as part of the y2038 conversion back in 2018, but
the newer architectures that share a single table never did.

I did a semi-automated conversion of the asm-generic/unistd.h contents
into a syscall.tbl format, using the ABI field to take care of all
the relevant differences that are encoded using #ifdef checks in the
existing header.

Conversion of the architectures is done one at a time in order to
be able to review or revert them as needed.

support separated kmalloc buckets (in the following kmem_buckets_create()
patches and future codetag-based separation). Since this will provide
a mitigation for a very common case of exploits, it is recommended to
enable this feature for general purpose distros. By default, the new
Kconfig will be enabled if CONFIG_SLAB_FREELIST_HARDENED is enabled (and
it is added to the hardening.config Kconfig fragment).

To be able to choose which buckets to allocate from, make the buckets
available to the internal kmalloc interfaces by adding them as the
second argument, rather than depending on the buckets being chosen from
the fixed set of global buckets. Where the bucket is not available,
pass NULL, which means "use the default system kmalloc bucket set"
(the prior existing behavior), as implemented in kmalloc_slab().

To avoid adding the extra argument when !CONFIG_SLAB_BUCKETS, only the
top-level macros and static inlines use the buckets argument (where
they are stripped out and compiled out respectively). The actual extern
functions can then be built without the argument, and the internals
fall back to the global kmalloc buckets unconditionally.

e36b69e918 scripts/faddr2line: Invoke addr2line as a single long-running process 
Rather than invoking a separate addr2line process for each address, invoke
a single addr2line coprocess, and pass each address to its stdin. Previous
work [0] applied a similar change to perf, leading to a ~60x speed-up [1].

If using an object file that is _not_ vmlinux, faddr2line passes a section
name argument to addr2line. Because we do not know until runtime which
section names will be passed to addr2line, we cannot apply this change to
non-vmlinux object files. Hence, it only applies to vmlinux.

b8c7dd15ce kernel-wide: fix spelling mistakes like "assocative" -> "associative" 
There were several instances of the string "assocat" in the kernel, which
should have been spelled "associat", with the various endings of -ive,
-ed, -ion, and sometimes beginnging with dis-.

Add to the spelling dictionary the corrections so that future instances
will be caught by checkpatch, and fix the instances found.

Originally noticed by accident with a 'git grep socat'.
