60f802e2d6 selftests/bpf: Fix error compiling cgroup_ancestor.c with musl libc 
Existing code calls connect() with a 'struct sockaddr_in6 *' argument
where a 'struct sockaddr *' argument is declared, yielding compile errors
when building for mips64el/musl-libc:

cc1: all warnings being treated as errors

This only compiles because of a glibc extension allowing declaration of the
argument as a "transparent union" which includes both types above.

Explicitly cast the argument to allow compiling for both musl and glibc.

4deecdd29c bpf: fix unpopulated name_len field in perf_event link info 
Previously when retrieving `bpf_link_info.perf_event` for
kprobe/uprobe/tracepoint, the `name_len` field was not populated by the
kernel, leaving it to reflect the value initially set by the user. This
behavior was inconsistent with how other input/output string buffer
fields function (e.g. `raw_tracepoint.tp_name_len`).

This patch fills `name_len` with the actual size of the string name.

434247637c bpf: use kvzmalloc to allocate BPF verifier environment 
The kzmalloc call in bpf_check can fail when memory is very fragmented,
which in turn can lead to an OOM kill.

Use kvzmalloc to fall back to vmalloc when memory is too fragmented to
allocate an order 3 sized bpf verifier environment.

Admittedly this is not a very common case, and only happens on systems
where memory has already been squeezed close to the limit, but this does
not seem like much of a hot path, and it's a simple enough fix.

830b8e4942 Merge branch 'check-the-remaining-info_cnt-before-repeating-btf-fields' 
Hou Tao says:

====================
Check the remaining info_cnt before repeating btf fields

From: Hou Tao <houtao1@huawei.com>

Hi,

The patch set adds the missed check again info_cnt when flattening the
array of nested struct. The problem was spotted when developing dynptr
key support for hash map. Patch #1 adds the missed check and patch #2
adds three success test cases and one failure test case for the problem.

Comments are always welcome.

Change Log:
v2:
 * patch #1: check info_cnt in btf_repeat_fields()
 * patch #2: use a hard-coded number instead of BTF_FIELDS_MAX, because
             BTF_FIELDS_MAX is not always available in vmlinux.h (e.g.,
	     for llvm 17/18)

c456f08040 selftests/bpf: Add more test case for field flattening 
Add three success test cases to test the flattening of array of nested
struct. For these three tests, the number of special fields in map is
BTF_FIELDS_MAX, but the array is defined in structs with different
nested level.

Add one failure test case for the flattening as well. In the test case,
the number of special fields in map is BTF_FIELDS_MAX + 1. It will make
btf_parse_fields() in map_create() return -E2BIG, the creation of map
will succeed, but the load of program will fail because the btf_record
is invalid for the map.

49ebeb0c15 bpf: selftests: send packet to devmap redirect XDP 
The current xdp_devmap_attach test attaches a program
that redirects to another program via devmap.

It is, however, never executed, so do that to catch
any bugs that might occur during execution.

Also, execute the same for a veth pair so that we
also cover the non-generic path.

Warning: Running this without the bugfix in this series
will likely crash your system.

ca9984c5f0 bpf: devmap: provide rxq after redirect 
rxq contains a pointer to the device from where
the redirect happened. Currently, the BPF program
that was executed after a redirect via BPF_MAP_TYPE_DEVMAP*
does not have it set.

This is particularly bad since accessing ingress_ifindex, e.g.

SEC("xdp")
int prog(struct xdp_md *pkt)
{
        return bpf_redirect_map(&dev_redirect_map, 0, 0);
}

SEC("xdp/devmap")
int prog_after_redirect(struct xdp_md *pkt)
{
        bpf_printk("ifindex %i", pkt->ingress_ifindex);
        return XDP_PASS;
}

depends on access to rxq, so a NULL pointer gets dereferenced:

subsequently, an XDP redirect is performed using the same
bpf_redirect_info struct, the XDP path will get confused and end up
crashing, which syzbot managed to trigger.

With the stack-allocated bpf_redirect_info, the structure is no longer
shared between the SKB and XDP paths, so the crash doesn't happen
anymore. However, different code paths using identically-numbered flag
values in the same struct field still seems like a bit of a mess, so
this patch cleans that up by moving the flag definitions together and
redefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlap
with the flags used for XDP. It also adds a BUILD_BUG_ON() check to make
sure the overlap is not re-introduced by mistake.

a41b3828ec selftests/bpf: Verify that sync_linked_regs preserves subreg_def 
This test was added because of a bug in verifier.c:sync_linked_regs(),
upon range propagation it destroyed subreg_def marks for registers.
The test is written in a way to return an upper half of a register
that is affected by range propagation and must have it's subreg_def
preserved. This gives a return value of 0 and leads to undefined
return value if subreg_def mark is not preserved.

e9bd9c498c bpf: sync_linked_regs() must preserve subreg_def 
Range propagation must not affect subreg_def marks, otherwise the
following example is rewritten by verifier incorrectly when
BPF_F_TEST_RND_HI32 flag is set:

  0: call bpf_ktime_get_ns                   call bpf_ktime_get_ns
  1: r0 &= 0x7fffffff       after verifier   r0 &= 0x7fffffff
  2: w1 = w0                rewrites         w1 = w0
  3: if w0 < 10 goto +0     -------------->  r11 = 0x2f5674a6     (r)
  4: r1 >>= 32                               r11 <<= 32           (r)
  5: r0 = r1                                 r1 |= r11            (r)
  6: exit;                                   if w0 < 0xa goto pc+0
                                             r1 >>= 32
                                             r0 = r1
                                             exit

(or zero extension of w1 at (2) is missing for architectures that
 require zero extension for upper register half).

The following happens w/o this patch:
- r0 is marked as not a subreg at (0);
- w1 is marked as subreg at (2);
- w1 subreg_def is overridden at (3) by copy_register_state();
- w1 is read at (5) but mark_insn_zext() does not mark (2)
  for zero extension, because w1 subreg_def is not set;
- because of BPF_F_TEST_RND_HI32 flag verifier inserts random
  value for hi32 bits of (2) (marked (r));
- this random value is read at (5).

79952bdcbc f2fs-6.12-rc1 
In this series, the main changes include 1) converting major IO paths to use
 folio, and 2) adding various knobs to control GC more flexibly for Zoned
 devices. In addition, there are several patches to address corner cases of
 atomic file operations and better support for file pinning on zoned device.
 
 Enhancement:
  - add knobs to tune foreground/background GCs for Zoned devices
  - convert IO paths to use folio
  - reduce expensive checkpoint trigger frequency
  - allow F2FS_IPU_NOCACHE for pinned file
  - forcibly migrate to secure space for zoned device file pinning
  - get rid of buffer_head use
  - add write priority option based on zone UFS
  - get rid of online repair on corrupted directory
 
 Bug fix:
  - fix to don't panic system for no free segment fault injection
  - fix to don't set SB_RDONLY in f2fs_handle_critical_error()
  - avoid unused block when dio write in LFS mode
  - compress: don't redirty sparse cluster during {,de}compress
  - check discard support for conventional zones
  - atomic: prevent atomic file from being dirtied before commit
  - atomic: fix to check atomic_file in f2fs ioctl interfaces
  - atomic: fix to forbid dio in atomic_file
  - atomic: fix to truncate pagecache before on-disk metadata truncation
  - atomic: create COW inode from parent dentry
  - atomic: fix to avoid racing w/ GC
  - atomic: require FMODE_WRITE for atomic write ioctls
  - fix to wait page writeback before setting gcing flag
  - fix to avoid racing in between read and OPU dio write, dio completion
  - fix several potential integer overflows in file offsets and dir_block_index
  - fix to avoid use-after-free in f2fs_stop_gc_thread()
 
 As usual, there are several code clean-ups and refactorings.

ba0c0cb56f remoteproc: k3-m4: use the proper dependencies 
The TI_K3_M4_REMOTEPROC Kconfig entry selects OMAP2PLUS_MBOX, but that
driver in turn depends on other things, which the k4-m4 driver didn't.

This causes a Kconfig time warning:

  WARNING: unmet direct dependencies detected for OMAP2PLUS_MBOX
    Depends on [n]: MAILBOX [=y] && (ARCH_OMAP2PLUS || ARCH_K3)
    Selected by [m]:
    - TI_K3_M4_REMOTEPROC [=m] && REMOTEPROC [=y] && (ARCH_K3 || COMPILE_TEST [=y])

because you can't select something that is unavailable.

Make the dependencies for TI_K3_M4_REMOTEPROC match those of the
OMAP2PLUS_MBOX driver that it needs.

5c480f1da8 remoteproc updates for v6.12 
This adds remoteproc support for the Cortex M4F found in AM62x and AM64x
 of the TI K3 family, support for the modem remoteproc in the Qualcomm
 SDX75, and audio, compute and general-purpose DSPs of the Qualcomm
 SA8775P.
 
 The i.MX remoteproc driver gains support for blocking and non-blocking
 mailbox transmissions, followed by the implementation of poweroff and
 reboot mechanisms, using the same. This is followed by a few bug fixes
 and minor improvements.
 
 A few cleanups and bug fixes for the TI K3 DSP and R5F drivers are
 introduced.
 
 Support for mapping SRAM regions into the AMD-Xilinx Zynqmp R5 cores is
 added.
 
 The Ingenic, TI DA8xx, TI Keystone, TI K3, ST slim drivers are
 simplified using devres helpers for various allocations.
 
 Uses of of_{find,get}_property() are replaced with of_property_present()
 where possible.

 "Mostly just a set of fixes in here, or little changes that didn't get
  included in the initial pull request. This contains:

   - Move the SQPOLL napi polling outside the submission lock (Olivier)

   - Rename of the "copy buffers" API that got added in the 6.12 merge
     window. There's really no copying going on, it's just referencing
     the buffers. After a bit of consideration, decided that it was
     better to simply rename this to avoid potential confusion (me)

   - Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
     start + len tracking rather than having start / end in there, and
     by removing the caching of folio_mask when we can just calculate it
     from folio_shift when we need it (me)

   - Fixes for the SQPOLL affinity checking (me, Felix)

   - Fix for how cqring waiting checks for the presence of task_work.
     Just check it directly rather than check for a specific
     notification mechanism (me)

   - Tweak to how request linking is represented in tracing (me)

   - Fix a syzbot report that deliberately sets up a huge list of
     overflow entries, and then hits rcu stalls when flushing this list.
     Just check for the need to preempt, and drop/reacquire locks in the
     loop. There's no state maintained over the loop itself, and each
     entry is yanked from head-of-list (me)"

9ab27b0186 The core clk framework is left largely untouched this time around except for 
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
 more excited about the support for loading DT overlays from KUnit tests so that
 we can test how the clk framework parses DT nodes during clk registration. The
 clk framework has some places that are highly DeviceTree dependent so this
 charts the path to extend the KUnit tests to cover even more framework code in
 the future. I've got some more tests on the list that use the DT overlay
 support, but they uncovered issues with clk unregistration that I'm still
 working on fixing.
 
 Outside the core, the clk driver update pile is dominated by Qualcomm and
 Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
 things all over the place, like adding missing clk frequencies or moving
 defines for the number of clks out of DT binding headers into the drivers.
 There are even conversions of DT bindings to YAML and migration away from
 strings to describe clk topology. Overall it doesn't look unusual so I expect
 the new drivers to be where we'll have fixes in the coming weeks.
 
 Core:
  - KUnit tests for clk registration and fixed rate basic clk type
  - A couple more devm helpers, one consumer and one provider
  - Support for assigned-clock-rates-u64
 
 New Drivers:
  - Camera, display and GPU clocks on Qualcomm SM4450
  - Camera clocks on Qualcomm SM8150
  - Rockchip rk3576 clks
  - Microchip SAM9X7 clks
  - Renesas RZ/V2H(P) (R9A09G057) clks
 
 Updates:
  - Mark a bunch of struct freq_tbl const to reduce .data usage
  - Add Qualcomm MSM8226 A7PLL and Regera PLL support
  - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
    Trion, as they do differ
  - A number of fixes to the Qualcomm SM8550 display clock driver
  - Fold Qualcomm SM8650 display clock driver into SM8550 one
  - Add missing clocks and GDSCs needed for audio on Qualcomm MSM8998
  - Add missing USB MP resets, GPLL9, and QUPv3 DFS to Qualcomm SC8180X
  - Fix sdcc clk frequency tables on Qualcomm SC8180X
  - Drop the Qualcomm SM8150 gcc_cpuss_ahb_clk_src
  - Mark Qualcomm PCIe GDSCs as RET_ON on sm8250 and sm8540 to avoid them
    turning off during suspend
  - Use the HW_CTRL mechanism on Qualcomm SM8550 video clock controller
    GDSCs
  - Get rid of CLK_NR_CLKS defines in Rockchip DT binding headers
  - Some fixes for Rockchip rk3228 and rk3588
  - Exynos850: Add clock for Thermal Management Unit
  - Exynos7885: Fix duplicated ID in the header, add missing TOP PLLs and
    add clocks for USB block in the FSYS clock controller
  - ExynosAutov9: Add DPUM clock controller
  - ExynosAutov920: Add new (first) clock controllers: TOP and PERIC0
    (and a bit more complete bindings)
  - Use clk_hw pointer instead of fw_name for acm_aud_clk[0-1]_sel clocks
    on i.MX8Q as parents in ACM provider
  - Add i.MX95 NETCMIX support to the block control provider
  - Fix parents for ENETx_REF_SEL clocks on i.MX6UL
  - Add USB clocks, resets and power domains on Renesas RZ/G3S
  - Add Generic Timer (GTM), I2C Bus Interface (RIIC), SD/MMC Host
    Interface (SDHI) and Watchdog Timer (WDT) clocks and resets on
    Renesas RZ/V2H
  - Add PCIe, PWM, and CAN-FD clocks on Renesas R-Car V4M
  - Add LCD controller clocks and resets on Renesas RZ/G2UL
  - Add DMA clocks and resets on Renesas RZ/G3S
  - Add fractional multiplication PLL support on Renesas R-Car Gen4
  - Document support for the Renesas RZ/G2M v3.0 (r8a774a3) SoC
  - Support for the Microchip SAM9X7 SoC as follows:
  - Updates for the Microchip PLL drivers
  - DT binding documentation updates (for the new clock driver and for
    the slow clock controller that SAM9X7 is using)
  - A fix for the Microchip SAMA7G5 clock driver to avoid allocating more
    memory than necessary
  - Constify some Amlogic structs
  - Add SM1 eARC clocks for Amlogic
  - Introduce a symbol namespace for Amlogic clock specific symbols
  - Add reset controller support to audiomix block control on i.MX
  - Add CLK_SET_RATE_PARENT flag to all audiomix clocks and to
    i.MX7D lcdif_pixel_src clock
  - Fix parent clocks for earc_phy and audpll on i.MX8MP
  - Fix default parents for enet[12]_ref_sel on i.MX6UL

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "The core clk framework is left largely untouched this time around
  except for support for the newly ratified DT property
  'assigned-clock-rates-u64'.

  I'm much more excited about the support for loading DT overlays from
  KUnit tests so that we can test how the clk framework parses DT nodes
  during clk registration. The clk framework has some places that are
  highly DeviceTree dependent so this charts the path to extend the
  KUnit tests to cover even more framework code in the future. I've got
  some more tests on the list that use the DT overlay support, but they
  uncovered issues with clk unregistration that I'm still working on
  fixing.

  Outside the core, the clk driver update pile is dominated by Qualcomm
  and Renesas SoCs, making it fairly usual. Looking closer, there are
  fixes for things all over the place, like adding missing clk
  frequencies or moving defines for the number of clks out of DT binding
  headers into the drivers. There are even conversions of DT bindings to
  YAML and migration away from strings to describe clk topology. Overall
  it doesn't look unusual so I expect the new drivers to be where we'll
  have fixes in the coming weeks.

Linus Torvalds
4e2c9cd7dc i2c-for-6.12-rc1 
I2C core
 ========
 
 After 15 years of deprecation, the I2C_COMPAT symbol has finally been
 removed. Also client addresses are now locked during initialization to
 prevent race conditions between different kinds of instantiation. Scoped
 foreach OF child loops are now used. And the testunit has received some
 cleanups and documentation improvements as well as two new tests, one
 for repeated start and one for triggering SMBusAlert interrupts.
 
 I2C host drivers
 ================
 
 The DesignWare and the Renesas I2C drivers have received most of
 the changes in this pull request.
 
 The first has has undergone through a series of cleanups that
 have been sent to the mailing list a year ago for the first time
 and finally get merged in this pull request. They are many, from
 typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
 inline functions to librarieas) and many others.
 
 Besides that, all the DesignWare Kconfig options have been
 grouped under the I2C_DESIGNWARE_CORE and this required some
 adaptation in many of the kernel configuration files for
 different arm and mips boards.
 
 Follows the list of the rest of the changes grouped by type of
 change.
 
 Cleanups
 --------
 The Qualcomm Geni platform improves the exit path in the runtime
 resume function.
 
 The Intel LJCA driver loses "target_addr" parameter in
 ljca_i2c_stop() because it was unused.
 
 The MediaTek controller intializes the restart_flag in the
 transfer function using the ternary conditional operator ("? :")
 instead of initializing it in different parts.
 
 Constified a few global data structures in the virtio driver.
 
 The Renesas driver simplifies the bus speed handling in the init
 function making it more readable.
 
 Improved an if/else statement in probe function of the Renesas
 R-Car driver.
 
 The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
 of SET_RUNTIME_PM_OPS().
 
 Still in the iMX/MXC driver a comma ',' has been replaced by a
 semicolon ';', while in different drivers the ',' has been
 removed from the '{ }' delimiters.
 
 Finally three devm_clk_get_enabled() have been used to simplify
 the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
 Ingenic and MPC drivers.
 
 Refactors
 ---------
 The Nuvoton fixes a potential out of boundary array access. This
 is not a bug fix because the issue could never occur due to
 hardware not having the properties listed in the array. The
 change makes the driver more future proof and, at the same time,
 silences code analyzers.
 
 Improvements
 ------------
 The Renesas I2C (riic) driver undergoes several patches improving
 the runtime power management handling.
 
 The Intel i801 driver uses a more descriptive adapter's name to
 show the presence of the IDF feature.
 
 In the Intel Denverton (ismt) adapter the pending transactions
 are killed when irq's can't complete their handling, triggering a
 timeout. This could have been considered as a bug fix, but
 because, standing to Vasily, it's very sporadic, I preferred
 considering the patch rather as an improvement.
 
 New Feature
 -----------
 The Renesas I2C (riic) driver now supports the fast mode plus.
 
 New support
 -----------
 Added support for:
 
     - Renesas R9A08G045
     - Rockchip RK3576
     - KEBA I2C
     - Theobroma Systems Mule Multiplexer.
 
 The Keba comes with a new driver, i2c-keba.c.
 The Mule is an i2c multiplexer and it also comes with a new
 driver, mux/i2c-mux-mule.c.
 
 Core patch
 ----------
 This pull request includes also a patch in the I2C framework, in
 i2c-core-base.c where the runtime PM functions have been replaced
 in order to allow to be accessed during the device add.
 
 Devicetree
 ----------
 Some cleanups in the devicetree, as well. nVidia and Qualcomm
 bindings improve their "if:then:" blocks. While the aspeed
 binding loses the "multi-master" property because it was
 redundant.
 
 The i2c-sprd binding has been converted to YAML.
 
 AT24 updates

 - document a new model from giantec in DT bindings
