sched_ext: Defer scx_hardlockup() out of NMI
scx_hardlockup() runs from NMI and eventually calls scx_claim_exit(),
which takes scx_sched_lock. scx_sched_lock isn't NMI-safe and grabbing
it from NMI context can lead to deadlocks.
The hardlockup handler is best-effort recovery and the disable path it
triggers runs off of irq_work anyway. Move the handle_lockup() call into
an irq_work so it runs in IRQ context.
Fixes:

ring-buffer fix for 7.1:
- Fix accounting of persistent ring buffer rewind On boot up, the head page is moved back to the earliest point of the saved ring buffer. This is because the ring buffer being read by user space on a crash may not save the part it read. Rewinding the head page back to the earliest saved position helps keep those events from being lost. The number of events is also read during boot up and displayed in the stats file in the tracefs directory. It's also used for other accounting as well. On boot up, the "reader page" is accounted for but a rewind may put it back into the buffer and then the reader page may be accounted for again. Save off the original reader page and skip accounting it when scanning the pages in the ring buffer. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaevLRxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qsNBAQCO9T+3kbDLD/DxRBYjeMXhTg2iY2OV SHV9jEzcYTahmwEAqVCFY9sNxVYXait/C924SmHCSi1N0HrIuEzIEd29iwk= =bv+t -----END PGP SIGNATURE----- Merge tag 'trace-ring-buffer-v7.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ring-buffer fix from Steven Rostedt: - Fix accounting of persistent ring buffer rewind On boot up, the head page is moved back to the earliest point of the saved ring buffer.

Pull io_uring fixes from Jens Axboe:
- Fix for a NOMMU bug with io_uring, where NOMMU doesn't grab page refs
at mmap time. NOMMU also has entirely broken FOLL_PIN support, yet
here we are
- A few fixes covering minor issues introduced in this merge window
- data race annotation to shut up KCSAN for when io-wq limits are
applied
- A nospec addition for direct descriptor file updating. Rest of the
direct descriptor path already had this, but for some reason the
update did not. Now they are all the same
- Various minor defensive changes that claude identified and suggested
terrible fixes for, turned into actually useful cleanups:
- Use kvfree() for the imu cache. These can come from kmalloc or
vmalloc depending on size, but the in-cache ones are capped
where it's always kmalloc based. Change to kvfree() in the
cleanup path, making future changes unlikely to mess that up
- Negative kbuf consumption lengths. Can't happen right now, but
cqe->res is used directly, which if other codes changes could
then be an error value
- Fix for an issue with the futex code, where partial wakes on a
vectored fuxes would potentially wake the same futex twice, rather
than move on to the next one. This could confuse an application as it
would've expected the next futex to have been woken
- Fix for a bug with ring resizing, where SQEs or CQEs might not have
been copied correctly if large SQEs or CQEs are used in the ring.
Application side issue, where SQEs or CQEs might have been lost
during resize
- Fix for a bug where EPOLL_URING_WAKE might have been lost, causing a
multishot poll to not be terminated when it's nested, like it should
have been
- Fix for an issue with signed comparison of poll references for the
slow path
- Fix for a user struct UAF in the zcrx code
- Two minor zcrx cleanups

Description for this pull request:
- Fix potential data leakage by zeroing the portion of the straddle block
beyond initialized_size when reading non-resident attributes.
- Remove unnecessary zeroing in ntfs_punch_hole() for ranges beyond
initialized_size, as they are already returned as zeros on read.
- Fix writable check in ntfs_file_mmap_prepare() to correctly handle
shared mappings using VMA_SHARED_BIT | VMA_MAYWRITE_BIT.
- Use page allocation instead of kmemdup() for IOMAP_INLINE data to
ensure page-aligned address and avoid BUG trap in
iomap_inline_data_valid() caused by the page boundary check.
- Add a size check before memory allocation in ntfs_attr_readall() and
reject overly large attributes.
- Remove unneeded noop_direct_IO from ntfs_aops as it is no longer
required following the FMODE_CAN_ODIRECT flag.
- Fix seven static analysis warnings reported by Smatch.

subsystem (the large majority of this diffstat)
- lots of comedi driver updates and bugfixes
- coresight driver updates
- interconnect driver updates and additions
- mei driver updates
- binder (both rust and C versions) updates and fixes
- lots of other smaller driver subsystem updates and additions
All of these have been in linux-next for a while with no reported

- the usual large set of new IIO drivers and updates for that
subsystem (the large majority of this diffstat)
- lots of comedi driver updates and bugfixes
- coresight driver updates
- interconnect driver updates and additions
- mei driver updates
- binder (both rust and C versions) updates and fixes
- lots of other smaller driver subsystem updates and additions
All of these have been in linux-next for a while with no reported
issues"

spi: Fixes for v7.1
This is quite a big set of fixes, almost all from Johan Hovold who is on an ongoing quest to clean up issues with probe and removal handling in drivers. There isn't anything too concerning here especially with the deregistration stuff which will very rarely get run in production systems since this is all platform devices in the SoC on embedded hardware, but it's all real issues which should be fixed. There's more in flight here. We also have a few other minor fixes, one from Felix Gu along the same lines as Johan's work and a couple of documentation things. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmnrhSUACgkQJNaLcl1U h9C4HwgAgcnZgIZvPQp5mQ0G3sq1udBJQja4zYyQyuZt7o+1qLs/qiPw+KA1HV/C hVXFcns2Uy+Sqmi1fPlVadWsOODcwYz3wfS198Du8y4WqIeynVFYoYvXxQmAJYYW zq0VD9LE/5Y+ONwABzqkfgy7ZvNzykoRgodKPoruqnkYqU0ZH7iY/k7916vxk4+Z +8hCDlG5JHv7Uw1wAuftwnACIhsi4jN3f7wsvA++ac3OXKpDC/0l4JX2gBzPaxfI HaT5+W+tDIDk7IbQmweatMMIoi6cvjttieoh6HLqGdJZF0aI7IgH71CDAB+6fWrx kwZIkX2FL5+mVLA1vCUNjwkZDFS+pg== =MD5+ -----END PGP SIGNATURE----- Merge tag 'spi-fix-v7.1-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "This is quite a big set of fixes, almost all from Johan Hovold who is on an ongoing quest to clean up issues with probe and removal handling in drivers.

regmap: Fixes for v7.1
There's couple of patches here that came in since my pull request:
- What is effectively a quirk for shoehorning support for a wider range
of I2C regmaps on weirdly restricted SMBus controllers.
- One minor fix for a memory leak on in error handling in the dummy
driver used by the KUnit tests.

netfilter: nf_conntrack_sip: don't use simple_strtoul
Replace unsafe port parsing in epaddr_len(), ct_sip_parse_header_uri(),
and ct_sip_parse_request() with a new sip_parse_port() helper that
validates each digit against the buffer limit, eliminating the use of
simple_strtoul() which assumes NUL-terminated strings.
The previous code dereferenced pointers without bounds checks after
sip_parse_addr() and relied on simple_strtoul() on non-NUL-terminated
skb data. A port that reaches the buffer limit without a trailing
character is also rejected as malformed.
Also get rid of all simple_strtoul() usage in conntrack, prefer a
stricter version instead. There are intentional changes:
- Bail out if number is > UINT_MAX and indicate a failure, same for
too long sequences.
While we do accept 05535 as port 5535, we will not accept e.g.
'sip:10.0.0.1:005060'. While its syntactically valid under RFC 3261,
we should restrict this to not waste cycles when presented with
malformed packets with 64k '0' characters.
- Force base 10 in ct_sip_parse_numerical_param(). This is used to fetch
'expire=' and 'rports='; both are expected to use base-10.
- In nf_nat_sip.c, only accept the parsed value if its within the 1k-64k
range.
- epaddr_len now returns 0 if the port is invalid, as it already does
for invalid ip addresses. This is intentional. nf_conntrack_sip
performs lots of guesswork to find the right parts of the message
to parse. Being stricter could break existing setups.
Connection tracking helpers are designed to allow traffic to
pass, not to block it.
Based on an earlier patch from Jenny Guanni Qu <qguanni@gmail.com>.

netfilter: reject zero shift in nft_bitwise
Reject zero shift operands for nft_bitwise left and right shift
expressions during initialization.
The carry propagation logic computes the carry from the adjacent 32-bit
word using BITS_PER_TYPE(u32) - shift. A zero shift operand turns this
into a 32-bit shift, which is undefined behaviour.
Reject zero shift operands in the control plane, alongside the existing
check for values greater than or equal to 32, so malformed rules never
reach the packet path.

netfilter: xt_policy: fix strict mode inbound policy matching
match_policy_in() walks sec_path entries from the last transform to the
first one, but strict policy matching needs to consume info->pol[] in
the same forward order as the rule layout.
Derive the strict-match policy position from the number of transforms
already consumed so that multi-element inbound rules are matched
consistently.

Pull RISC-V updates from Paul Walmsley:
"There is one significant change outside arch/riscv in this pull
request: the addition of a set of KUnit tests for strlen(), strnlen(),
and strrchr().
Otherwise, the most notable changes are to add some RISC-V-specific
string function implementations, to remove XIP kernel support, to add
hardware error exception handling, and to optimize our runtime
unaligned access speed testing.
A few comments on the motivation for removing XIP support. It's been
broken in the RISC-V kernel for months. The code is not easy to
maintain. Furthermore, for XIP support to truly be useful for RISC-V,
we think that compile-time feature switches would need to be added for
many of the RISC-V ISA features and microarchitectural properties that
are currently implemented with runtime patching. No one has stepped
forward to take responsibility for that work, so many of us think it's
best to remove it until clear use cases and champions emerge.
Summary:
- Add Kunit correctness testing and microbenchmarks for strlen(),
strnlen(), and strrchr()
- Add RISC-V-specific strnlen(), strchr(), strrchr() implementations
- Add hardware error exception handling
- Clean up and optimize our unaligned access probe code

Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden to core networking developers. syzbot loves to find bugs in BKL-era code, and noobs try to fix them. If we want to have a fighting chance of surviving the LLM-pocalypse this code needs to find a dedicated owner or get deleted. We've talked about these deletions multiple times in the past and every time someone wanted the code to stay. It is never very clear to me how many of those people actually use the code vs are just nostalgic to see it go. Amateur radio did have occasional users (or so I think) but most users switched to user space implementations since its all super slow stuff. Nobody stepped up to maintain the kernel code. We were lucky enough to find someone who wants to help with NFC so we're giving that a chance. Let's try to put the rest of this code behind us.

GFX V11 has GC block as default off IP. Every time AMDGPU driver sends a request to PMFW to unload MP1, PMFW will put GC in reset and power down the voltage.Hence, skipping reset for APUs with GFX V11 or later to avoid reset related failures. Fixes: |

drm/amdgpu/gfx6: Support harvested SI chips with disabled TCCs (v2)
This commit fixes amdgpu to work on the Radeon HD 7870 XT which has never worked with the Linux open source drivers before. Some boards have "harvested" chips, meaning that some parts of the chip are disabled and fused, and it's sold for cheaper and under a different marketing name. On a harvested chip, any of the following can be disabled: - CUs (Compute Units) - RBs (Render Backend, aka. ROP) - Memory channels (ie. the chip has a lower bandwidth) - TCCs (ie. less L2 cache) Handle chips with harvested TCCs by patching the registers that configure how TCCs are mapped. If some TCCs are disabled, we need to make sure that the disabled TCCs are not used, and the remaining TCCs are used optimally. TCP_CHAN_STEER_LO/HI control which TCC is used by TCP channels. TCP_ADDR_CONFIG.NUM_TCC_BANKS controls how many channels are used. Note that the TCC configuration is highly relevant to performance. Suboptimal configuration (eg. CHAN_STEER=0) can significantly reduce gaming performance. For optimal performance: - Rely on the CHAN_STEER from the golden registers table, only skip disabled TCCs but keep the mapping order. - Limit NUM_TCC_BANKS to number of active TCCs to avoid thrashing, which performs better than using the same TCC twice. v2: - Also consider CGTS_USER_TCC_DISABLE for disabled TCCs.

drm/amdgpu/uvd3.1: Don't validate the firmware when already validated
UVD 3.1 firmware validation seems to always fail after attempting it when it had already been validated. (This works similarly with the VCE 1.0 as well.) Don't attempt repeating the validation when it's already done. This caused issues in situations when the system isn't able to suspend the GPU properly and so the GPU isn't actually powered down. Then amdgpu would fail when calling the IP block resume function. Closes: https://gitlab.freedesktop.org/drm/amd/-/work_items/2887 Fixes: |

There were multiple issues in that code. First of all the order between the reset semaphore and the mm_lock was wrong (e.g. copy_to_user) was called while holding the lock. Then we allocated memory while holding the reset semaphore which is also a pretty big bug and can deadlock. Then we used down_read_trylock() instead of waiting for the reset to finish.

When the GART placement is set to AMDGPU_GART_PLACEMENT_LOW: Make sure that GART does not overlap with VRAM when VRAM is configured to be in the low address space. Solve this according to the following logic: - When GART fits before VRAM, use zero address for GART - Otherwise, put GART after the end of VRAM, aligned to 4 GiB Previously, I had assumed this was not possible so it was OK to not handle it, but now we got a report from a user who has a board that is configured this way.

drm/amdgpu: avoid double drm_exec_fini() in userq validate
When new_addition is true, amdgpu_userq_vm_validate() calls drm_exec_fini(&exec) before iterating over the collected HMM ranges and calling amdgpu_ttm_tt_get_user_pages(). If amdgpu_ttm_tt_get_user_pages() fails in that path, the code jumps to unlock_all and calls drm_exec_fini(&exec) a second time on the same exec object. drm_exec_fini() is not idempotent: it frees exec->objects and may also drop exec->contended and finalize the ww acquire context. Route that error path directly to the range cleanup once exec has already been finalized. Fixes: |

drm/amdgpu: fix zero-size GDS range init on RDNA4
RDNA4 (GFX 12) hardware removes the GDS, GWS, and OA on-chip memory
resources. The gfx_v12_0 initialisation code correctly leaves
adev->gds.gds_size, adev->gds.gws_size, and adev->gds.oa_size at
zero to reflect this.
amdgpu_ttm_init() unconditionally calls amdgpu_ttm_init_on_chip() for
each of these resources regardless of size. When the size is zero,
amdgpu_ttm_init_on_chip() forwards the call to ttm_range_man_init(),
which calls drm_mm_init(mm, 0, 0). drm_mm_init() immediately fires
DRM_MM_BUG_ON(start + size <= start) -- trivially true when size is
zero -- crashing the kernel during modprobe of amdgpu on an RX 9070 XT.
Guard against this by returning 0 early from
amdgpu_ttm_init_on_chip() when size_in_page is zero. This skips TTM
resource manager registration for hardware resources that are absent,
without affecting any other GPU type.
DRM_MM_BUG_ON() only asserts if CONFIG_DRM_DEBUG_MM is enabled in
the kernel config. This is apparently rarely enabled as these chips
have been in the market for over a year and this issue was only reported
now.

kbuild: Never respect CONFIG_WERROR / W=e to fixdep
The fixdep hostprog may be built multiple times during a single build.
Once during the configuration phase and later during the regular phase.
As only the regular build phase respects CONFIG_WERROR / W=e, the
compiler flags might change between the phases, leading to rebuilds.
Example, the rebuilds will happen twice on each invocation of the build:
$ make allyesconfig prepare
make[1]: Entering directory '/tmp/deleteme'
HOSTCC scripts/basic/fixdep
#
# No change to .config
#
HOSTCC scripts/basic/fixdep
DESCEND objtool
INSTALL libsubcmd_headers
make[1]: Leaving directory '/tmp/deleteme'
Fix the compilation flags used for scripts/basic/ before
scripts/Makefile.warn is evaluated to stop CONFIG_WERROR / W=e
influencing the fixdep build to avoid the spurious rebuilds.

KVM: arm64: Wake-up from WFI when iqrchip is in userspace
It appears that there is nothing in the wake-up path that
evaluates whether the in-kernel interrupts are pending unless
we have a vgic.
This means that the userspace irqchip support has been broken for
about four years, and nobody noticed. It was also broken before
as we wouldn't wake-up on a PMU interrupt, but hey, who cares...
It is probably time to remove the feature altogether, because it
was a terrible idea 10 years ago, and it still is.
