sound fixes for 6.11-rc7
Hopefully the last PR for 6.11, at least for this level of amount. In addition to the usual HD-audio quirks, there are more changes in ASoC, but all look small and device-specific fixes, and nothing stands out. The only slightly big change is sunxi I2S fix, which looks quite safe to apply, too. -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmbaxkIOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE/xDQ/9ESOhr5vmViDZ/LOXrmA36Mc7byvDE0ku9TsN bEBRSo2J5GJX3ty9ST6Pwm4jRlPAXRrqqWNhP2b+nQTTdzRWFQC58m79BSGmGWRA qyuFPakn1tiCdl5rvHS7hpYfzMkc8amVILhhJyhbv7Zg0UPriczPL3JI/W2GAJRs vMuHAD2ulSTVcJdYGgvny5JGWVQ649mQw7rfp+h3G9kXRLyOXKamGLU2e68TEZLq owUifBS1rC7+jXUn6dZ5MU86BLMQFCCDCOUjEEklH08Y+1DzqlS+JE80NcJlUBo8 xNHoY1xFqDb0DAPb3w7P5IfCMBkb1I2uyHyMQg+SJeN05qXiSAKIsZhr5/NeivFq clB6R9l3tmN66lQEqr1ZxBEx6Sgr40Deh2qFOjyq7xsm+PRU4oPdels4+awRTWPy 8fr/L2wWtYGGILM7iDkasgVeYQZGFJ7AG0gC0AyUoKtEcZZsQUiwfAWT85K4GLP9 mmUMwqZH3nKtOxXgphSGbxOnep9cWNT7IJ/NXZ1iNGlByLXVDk5fIlOUK8983gCx duuFA1CpR3RwayGOo2UIwT62+qOTtfwGGKkHAPWjbBWa/daNxI8UEaHH/XEH3qyy iK8xFIkKimi95hjAA8FmVN6aGkeu3OCnQvdzbP3f3k0Tj1xe3t42xhPmQVl9yrpu lwIdl20= =npz1 -----END PGP SIGNATURE----- Merge tag 'sound-6.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "Hopefully the last PR for 6.11, at least for this level of amount.

ASoC: Fixes for v6.11
A larger set of fixes than I'd like at this point, but mainly due to people working on fixing module autoloading by adding missing exports of ID tables rather than anything particularly concerning.

drm/panthor: Restrict high priorities on group_create
We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service. We now only allow the DRM master or users with the CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM. As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do. Additionally, as those checks are performed at the ioctl level, panthor_group_create now only check for priority level validity. [1] |

ASoC: SOF: ipc: replace "enum sof_comp_type" field with "uint32_t"
Normally, the type of enums is "unsigned int" or "int". GCC has the "-fshort-enums" option, which instructs the compiler to use the smallest data type that can hold all the values in the enum (i.e: char, short, int or their unsigned variants). According to the GCC documentation, "-fshort-enums" may be default on some targets. This seems to be the case for SOF when built for a certain 32-bit ARM platform. On Linux, this is not the case (tested with "aarch64-linux-gnu-gcc") which means enums such as "enum sof_comp_type" will end up having different sizes on Linux and SOF. Since "enum sof_comp_type" is used in IPC-related structures such as "struct sof_ipc_comp", this means the fields of the structures will end up being placed at different offsets. This, in turn, leads to SOF not being able to properly interpret data passed from Linux. With this in mind, replace "enum sof_comp_type" from "struct sof_ipc_comp" with "uint32_t".

When file leases were split out of file locks the name of the file lock slab cache was used for the file leases slab cache as well. - Fix a type in take_fd() helper. - Fix infinite directory iteration for stable offsets in tmpfs. - When the icache is pruned all reclaimable inodes are marked with I_FREEING and other processes that try to lookup such inodes will block. But some filesystems like ext4 can trigger lookups in their inode evict callback causing deadlocks. Ext4 does such lookups if the ea_inode feature is used whereby a separate inode may be used to store xattrs. Introduce I_LRU_ISOLATING which pins the inode while its pages are reclaimed. This avoids inode deletion during inode_lru_isolate() avoiding the deadlock and evict is made to wait until I_LRU_ISOLATING is done. netfs: - Fault in smaller chunks for non-large folio mappings for filesystems that haven't been converted to large folios yet. - Fix the CONFIG_NETFS_DEBUG config option. The config option was renamed a short while ago and that introduced two minor issues. First, it depended on CONFIG_NETFS whereas it wants to depend on CONFIG_NETFS_SUPPORT. The former doesn't exist, while the latter does. Second, the documentation for the config option wasn't fixed up. - Revert the removal of the PG_private_2 writeback flag as ceph is using it and fix how that flag is handled in netfs. - Fix DIO reads on 9p. A program watching a file on a 9p mount wouldn't see any changes in the size of the file being exported by the server if the file was changed directly in the source filesystem. Fix this by attempting to read the full size specified when a DIO read is requested. - Fix a NULL pointer dereference bug due to a data race where a cachefiles cookies was retired even though it was still in use.

uretprobe: change syscall number, again
Despite multiple attempts to get the syscall number assignment right for the newly added uretprobe syscall, we ended up with a bit of a mess: - The number is defined as 467 based on the assumption that the xattrat family of syscalls would use 463 through 466, but those did not make it into 6.11. - The include/uapi/asm-generic/unistd.h file still lists the number 463, but the new scripts/syscall.tbl that was supposed to have the same data lists 467 instead as the number for arc, arm64, csky, hexagon, loongarch, nios2, openrisc and riscv. None of these architectures actually provide a uretprobe syscall. - All the other architectures (powerpc, arm, mips, ...) don't list this syscall at all. There are two ways to make it consistent again: either list it with the same syscall number on all architectures, or only list it on x86 but not in scripts/syscall.tbl and asm-generic/unistd.h. Based on the most recent discussion, it seems like we won't need it anywhere else, so just remove the inconsistent assignment and instead move the x86 number to the next available one in the architecture specific range, which is 335.

- 875fa64577 ("mm/hugetlb_vmemmap: fix race with speculative PFN
walkers") is known to cause a performance regression (https://lore.kernel.org/all/3acefad9-96e5-4681-8014-827d6be71c7a@linux.ibm.com/T/#mfa809800a7862fb5bdf834c6f71a3a5113eb83ff). Yu has a fix which I'll send along later via the hotfixes branch. - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code. These fixes are also targetted at -stable kernels. - Ryusuke Konishi's series "nilfs2: fix potential issues related to reserved inodes" does that. This should actually be in the mm-nonmm-stable tree, along with the many other nilfs2 patches. My bad. - More folio conversions from Kefeng Wang in the series "mm: convert to folio_alloc_mpol()" - Kemeng Shi has sent some cleanups to the writeback code in the series "Add helper functions to remove repeated code and improve readability of cgroup writeback" - Kairui Song has made the swap code a little smaller and a little faster in the series "mm/swap: clean up and optimize swap cache index". - In the series "mm/memory: cleanly support zeropage in vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David Hildenbrand has reworked the rather sketchy handling of the use of the zeropage in MAP_SHARED mappings. I don't see any runtime effects here - more a cleanup/understandability/maintainablity thing. - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of higher addresses, for aarch64. The (poorly named) series is "Restructure va_high_addr_switch". - The core TLB handling code gets some cleanups and possible slight optimizations in Bang Li's series "Add update_mmu_tlb_range() to simplify code". - Jane Chu has improved the handling of our fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the series "Enhance soft hwpoison handling and injection". - Jeff Johnson has sent a billion patches everywhere to add MODULE_DESCRIPTION() to everything. Some landed in this pull. - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has simplified migration's use of hardware-offload memory copying. - Yosry Ahmed performs more folio API conversions in his series "mm: zswap: trivial folio conversions". - In the series "large folios swap-in: handle refault cases first", Chuanhua Han inches us forward in the handling of large pages in the swap code. This is a cleanup and optimization, working toward the end objective of full support of large folio swapin/out. - In the series "mm,swap: cleanup VMA based swap readahead window calculation", Huang Ying has contributed some cleanups and a possible fixlet to his VMA based swap readahead code. - In the series "add mTHP support for anonymous shmem" Baolin Wang has taught anonymous shmem mappings to use multisize THP. By default this is a no-op - users must opt in vis sysfs controls. Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Is anyone reading this stuff? If so, email me! - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers. From SeongJae Park. - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does that. - David Hildenbrand sends along more cleanups, this time against the migration code. The series is "mm/migrate: move NUMA hinting fault folio isolation + checks under PTL". - Jan Kara has found quite a lot of strangenesses and minor errors in the readahead code. He addresses this in the series "mm: Fix various readahead quirks". - SeongJae Park's series "selftests/damon: test DAMOS tried regions and {min,max}_nr_regions" adds features and addresses errors in DAMON's self testing code. - Gavin Shan has found a userspace-triggerable WARN in the pagecache code. The series "mm/filemap: Limit page cache size to that supported by xarray" addresses this. The series is marked cc:stable. - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations and cleanup" cleans up and slightly optimizes KSM. - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of code motion. The series (which also makes the memcg-v1 code Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put under config option" and "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1" - Dan Schatzberg's series "Add swappiness argument to memory.reclaim" adds an additional feature to this cgroup-v2 control file. - The series "Userspace controls soft-offline pages" from Jiaqi Yan permits userspace to stop the kernel's automatic treatment of excessive correctable memory errors. In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZp2C+QAKCRDdBJ7gKXxA joTkAQDvjqOoFStqk4GU3OXMYB7WCU/ZQMFG0iuu1EEwTVDZ4QEA8CnG7seek1R3 xEoo+vw0sWWeLV3qzsxnCA1BJ8cTJA8= =z0Lf -----END PGP SIGNATURE----- Merge tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code.

In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. * tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (411 commits) mm/mglru: fix ineffective protection calculation mm/zswap: fix a white space issue mm/hugetlb: fix kernel NULL pointer dereference when migrating hugetlb folio mm/hugetlb: fix possible recursive locking detected warning mm/gup: clear the LRU flag of a page before adding to LRU batch mm/numa_balancing: teach mpol_to_str about the balancing mode mm: memcg1: convert charge move flags to unsigned long long alloc_tag: fix page_ext_get/page_ext_put sequence during page splitting lib: reuse page_ext_data() to obtain codetag_ref lib: add missing newline character in the warning message mm/mglru: fix overshooting shrinker memory mm/mglru: fix div-by-zero in vmpressure_calc_level() mm/kmemleak: replace strncpy() with strscpy() mm, page_alloc: put should_fail_alloc_page() back behing CONFIG_FAIL_PAGE_ALLOC mm, slab: put should_failslab() back behind CONFIG_SHOULD_FAILSLAB mm: ignore data-race in __swap_writepage hugetlbfs: ensure generic_hugetlb_get_unmapped_area() returns higher address than mmap_min_addr mm: shmem: rename mTHP shmem counters mm: swap_state: use folio_alloc_mpol() in __read_swap_cache_async() mm/migrate: putback split folios when numa hint migration fails ... |

RISC-V: * Redirect AMO load/store access fault traps to guest * perf kvm stat support * Use guest files for IMSIC virtualization, when available ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA extensions is coming through the RISC-V tree. s390: * Assortment of tiny fixes which are not time critical x86: * Fixes for Xen emulation. * Add a global struct to consolidate tracking of host values, e.g. EFER * Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the effective APIC bus frequency, because TDX. * Print the name of the APICv/AVIC inhibits in the relevant tracepoint. * Clean up KVM's handling of vendor specific emulation to consistently act on "compatible with Intel/AMD", versus checking for a specific vendor. * Drop MTRR virtualization, and instead always honor guest PAT on CPUs that support self-snoop. * Update to the newfangled Intel CPU FMS infrastructure. * Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as it reads '0' and writes from userspace are ignored. * Misc cleanups x86 - MMU: * Small cleanups, renames and refactoring extracted from the upcoming Intel TDX support. * Don't allocate kvm_mmu_page.shadowed_translation for shadow pages that can't hold leafs SPTEs. * Unconditionally drop mmu_lock when allocating TDP MMU page tables for eager page splitting, to avoid stalling vCPUs when splitting huge pages. * Bug the VM instead of simply warning if KVM tries to split a SPTE that is non-present or not-huge. KVM is guaranteed to end up in a broken state because the callers fully expect a valid SPTE, it's all but dangerous to let more MMU changes happen afterwards. x86 - AMD: * Make per-CPU save_area allocations NUMA-aware. * Force sev_es_host_save_area() to be inlined to avoid calling into an instrumentable function from noinstr code. * Base support for running SEV-SNP guests. API-wise, this includes a new KVM_X86_SNP_VM type, encrypting/measure the initial image into guest memory, and finalizing it before launching it. Internally, there are some gmem/mmu hooks needed to prepare gmem-allocated pages before mapping them into guest private memory ranges. This includes basic support for attestation guest requests, enough to say that KVM supports the GHCB 2.0 specification. There is no support yet for loading into the firmware those signing keys to be used for attestation requests, and therefore no need yet for the host to provide certificate data for those keys. To support fetching certificate data from userspace, a new KVM exit type will be needed to handle fetching the certificate from userspace. An attempt to define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this was introduced in v1 of this patchset, but is still being discussed by community, so for now this patchset only implements a stub version of SNP Extended Guest Requests that does not provide certificate data. x86 - Intel: * Remove an unnecessary EPT TLB flush when enabling hardware. * Fix a series of bugs that cause KVM to fail to detect nested pending posted interrupts as valid wake eents for a vCPU executing HLT in L2 (with HLT-exiting disable by L1). * KVM: x86: Suppress MMIO that is triggered during task switch emulation Explicitly suppress userspace emulated MMIO exits that are triggered when emulating a task switch as KVM doesn't support userspace MMIO during complex (multi-step) emulation. Silently ignoring the exit request can result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace for some other reason prior to purging mmio_needed. See commit |

random: note that RNDGETPOOL was removed in 2.6.9-rc2
RNDGETPOOL was thankfully removed twenty years ago, but it's stuck around in headers. Probably removing it from uapi headers isn't great in case there are some weird users out there, but we should at least mark this as having been removed, to save future readers the same goose chase I just went on.

random: introduce generic vDSO getrandom() implementation
Provide a generic C vDSO getrandom() implementation, which operates on an opaque state returned by vgetrandom_alloc() and produces random bytes the same way as getrandom(). This has the following API signature: ssize_t vgetrandom(void *buffer, size_t len, unsigned int flags, void *opaque_state, size_t opaque_len); The return value and the first three arguments are the same as ordinary getrandom(), while the last two arguments are a pointer to the opaque allocated state and its size. Were all five arguments passed to the getrandom() syscall, nothing different would happen, and the functions would have the exact same behavior. The actual vDSO RNG algorithm implemented is the same one implemented by drivers/char/random.c, using the same fast-erasure techniques as that. Should the in-kernel implementation change, so too will the vDSO one. It requires an implementation of ChaCha20 that does not use any stack, in order to maintain forward secrecy if a multi-threaded program forks (though this does not account for a similar issue with SA_SIGINFO copying registers to the stack), so this is left as an architecture-specific fill-in. Stack-less ChaCha20 is an easy algorithm to implement on a variety of architectures, so this shouldn't be too onerous. Initially, the state is keyless, and so the first call makes a getrandom() syscall to generate that key, and then uses it for subsequent calls. By keeping track of a generation counter, it knows when its key is invalidated and it should fetch a new one using the syscall. Later, more than just a generation counter might be used. Since MADV_WIPEONFORK is set on the opaque state, the key and related state is wiped during a fork(), so secrets don't roll over into new processes, and the same state doesn't accidentally generate the same random stream. The generation counter, as well, is always >0, so that the 0 counter is a useful indication of a fork() or otherwise uninitialized state. If the kernel RNG is not yet initialized, then the vDSO always calls the syscall, because that behavior cannot be emulated in userspace, but fortunately that state is short lived and only during early boot. If it has been initialized, then there is no need to inspect the `flags` argument, because the behavior does not change post-initialization regardless of the `flags` value. Since the opaque state passed to it is mutated, vDSO getrandom() is not reentrant, when used with the same opaque state, which libc should be mindful of. The function works over an opaque per-thread state of a particular size, which must be marked VM_WIPEONFORK, VM_DONTDUMP, VM_NORESERVE, and VM_DROPPABLE for proper operation. Over time, the nuances of these allocations may change or grow or even differ based on architectural features. The opaque state passed to vDSO getrandom() must be allocated using the mmap_flags and mmap_prot parameters provided by the vgetrandom_opaque_params struct, which also contains the size of each state. That struct can be obtained with a call to vgetrandom(NULL, 0, 0, ¶ms, ~0UL). Then, libc can call mmap(2) and slice up the returned array into a state per each thread, while ensuring that no single state straddles a page boundary. Libc is expected to allocate a chunk of these on first use, and then dole them out to threads as they're created, allocating more when needed. vDSO getrandom() provides the ability for userspace to generate random bytes quickly and safely, and is intended to be integrated into libc's thread management. As an illustrative example, the introduced code in the vdso_test_getrandom self test later in this series might be used to do the same outside of libc. In a libc the various pthread-isms are expected to be elided into libc internals. Reviewed-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |

mm: add MAP_DROPPABLE for designating always lazily freeable mappings
The vDSO getrandom() implementation works with a buffer allocated with a new system call that has certain requirements: - It shouldn't be written to core dumps. * Easy: VM_DONTDUMP. - It should be zeroed on fork. * Easy: VM_WIPEONFORK. - It shouldn't be written to swap. * Uh-oh: mlock is rlimited. * Uh-oh: mlock isn't inherited by forks. - It shouldn't reserve actual memory, but it also shouldn't crash when page faulting in memory if none is available * Uh-oh: VM_NORESERVE means segfaults. It turns out that the vDSO getrandom() function has three really nice characteristics that we can exploit to solve this problem: 1) Due to being wiped during fork(), the vDSO code is already robust to having the contents of the pages it reads zeroed out midway through the function's execution. 2) In the absolute worst case of whatever contingency we're coding for, we have the option to fallback to the getrandom() syscall, and everything is fine. 3) The buffers the function uses are only ever useful for a maximum of 60 seconds -- a sort of cache, rather than a long term allocation. These characteristics mean that we can introduce VM_DROPPABLE, which has the following semantics: a) It never is written out to swap. b) Under memory pressure, mm can just drop the pages (so that they're zero when read back again). c) It is inherited by fork. d) It doesn't count against the mlock budget, since nothing is locked. e) If there's not enough memory to service a page fault, it's not fatal, and no signal is sent. This way, allocations used by vDSO getrandom() can use: VM_DROPPABLE | VM_DONTDUMP | VM_WIPEONFORK | VM_NORESERVE And there will be no problem with OOMing, crashing on overcommitment, using memory when not in use, not wiping on fork(), coredumps, or writing out to swap. In order to let vDSO getrandom() use this, expose these via mmap(2) as MAP_DROPPABLE. Note that this involves removing the MADV_FREE special case from sort_folio(), which according to Yu Zhao is unnecessary and will simply result in an extra call to shrink_folio_list() in the worst case. The chunk removed reenables the swapbacked flag, which we don't want for VM_DROPPABLE, and we can't conditionalize it here because there isn't a vma reference available. Finally, the provided self test ensures that this is working as desired. Cc: linux-mm@kvack.org Acked-by: David Hildenbrand <david@redhat.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> |

iommufd for 6.11 merge window
Major changes: - The iova_bitmap logic for efficiently reporting dirty pages back to userspace has a few more tricky corner case bugs that have been resolved and backed with new tests. The revised version has simpler logic. - Shared branch with iommu for handle support when doing domain attach. Handles allow the domain owner to include additional private data on a per-device basis. - IO Page Fault Reporting to userspace via iommufd. Page faults can be generated on fault capable HWPTs when a translation is not present. Routing them to userspace would allow a VMM to be able to virtualize them into an emulated vIOMMU. This is the next step to fully enabling vSVA support. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZpfo4AAKCRCFwuHvBreF YTO6APwMLxeWmHbE1H+7ZPuXP7B1aDuwRLczZOo3i816pIj+bQD+OywEA/NcljK6 6NLeqyUe7tECtVrFPSiRT9lWVuzZSQs= =rnN/ -----END PGP SIGNATURE----- Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd updates from Jason Gunthorpe: - The iova_bitmap logic for efficiently reporting dirty pages back to userspace has a few more tricky corner case bugs that have been resolved and backed with new tests.

Probes updates for v6.11:
Uprobes: - x86/shstk: Make return uprobe work with shadow stack. - Add uretprobe syscall which speeds up the uretprobe 10-30% faster. This syscall is automatically used from user-space trampolines which are generated by the uretprobe. If this syscall is used by normal user program, it will cause SIGILL. Note that this is currently only implemented on x86_64. (This also has 2 fixes for adjusting the syscall number to avoid conflict with new *attrat syscalls.) - uprobes/perf: fix user stack traces in the presence of pending uretprobe. This corrects the uretprobe's trampoline address in the stacktrace with correct return address. - selftests/x86: Add a return uprobe with shadow stack test. - selftests/bpf: Add uretprobe syscall related tests. . test case for register integrity check. . test case with register changing case. . test case for uretprobe syscall without uprobes (expected to be failed). . test case for uretprobe with shadow stack. - selftests/bpf: add test validating uprobe/uretprobe stack traces - MAINTAINERS: Add uprobes entry. This does not specify the tree but to clarify who maintains and reviews the uprobes. Kprobes: - tracing/kprobes: Test case cleanups. Replace redundant WARN_ON_ONCE() + pr_warn() with WARN_ONCE() and remove unnecessary code from selftest. - tracing/kprobes: Add symbol counting check when module loads. This checks the uniqueness of the probed symbol on modules. The same check has already done for kernel symbols. (This also has a fix for build error with CONFIG_MODULES=n) Cleanup: - Add MODULE_DESCRIPTION() macros for fprobe and kprobe examples. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmaWYxwbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8bsUgH/3JcSzDZujQWCZ1f4fJn QecvTFSYcCl6ck8+/3wm4EsgeCXIFOyPnoPc7k2Gm+l6Dlk1DKGV6wV4tuKFUq9X 9mplcwoVA0Ln+EX9zv9v4s99yUGxcU9xjgC9XT7J52SvqYncPIi6dR0Z9wlJBmyd Bx3cZk+wSzCYaoqYngI2fKlzsEcYgDIP999fQPRi0HGzNZujc4xeJyjCTC/48yWO 9kreRQq6wFdgRQTwMcR/fKPDKIGZQCU8jkXv5crVV5K3rNaBcwBmCJJMP8PzPU0V UQ0+8RZK+Qk8SBwXcMNVRqm/efTderob4IYxP8OBe5wjAIE7+vu8r6sqwxRIS54M Cyg= =DRSr -----END PGP SIGNATURE----- Merge tag 'probes-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes updates from Masami Hiramatsu: "Uprobes: - x86/shstk: Make return uprobe work with shadow stack - Add uretprobe syscall which speeds up the uretprobe 10-30% faster.

landlock: Various documentation improvements
* Fix some typos, incomplete or confusing phrases. * Split paragraphs where appropriate. * List the same error code multiple times, if it has multiple possible causes. * Bring wording closer to the man page wording, which has undergone more thorough review (esp. for LANDLOCK_ACCESS_FS_WRITE_FILE). * Small semantic clarifications * Call the ephemeral port range "ephemeral" * Clarify reasons for EFAULT in landlock_add_rule() * Clarify @rule_type doc for landlock_add_rule() This is a collection of small fixes which I collected when preparing the corresponding man pages [1].

NFSD 6.11 Release Notes
This is a light release containing optimizations, code clean-ups, and minor bug fixes. This development cycle focused on work outside of upstream kernel development: 1. Continuing to build upstream CI for NFSD based on kdevops 2. Continuing to focus on the quality of NFSD in LTS kernels 3. Participation in IETF nfsv4 WG discussions about NFSv4 ACLs, directory delegation, and NFSv4.2 COPY offload Notable features in v6.11 that were not pulled through the NFSD tree include NFS server-side support for the new pNFS NVMe layout type [RFC9561]. Functional testing for pNFS block layouts like this one has been introduced to our kdevops CI harness. Work on improving the resolution of file attribute time stamps in local filesystems is also ongoing tree-wide. As always I am grateful to NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmaVM0cACgkQM2qzM29m f5fzOQ//c5CXIF3zCLIUofm5eZSP2zIszmHR75rVTEnf0Ehm2BJRF6VZiTvWXRpz bOuswxfV1Bds+TofbPIP8jqDcMp8NIXemdb6+QMwh4FDY4M8t1v6TRYt35L6Ulrq bSV81aRS622ofQ35sRzwxpGX6rB6YbB+5L4EKuxdEqRKSB8rCxQcjPy2qypcWlRC hEAGDe3IiVxTz4VQBpASRqbH9Udw/XEqIhv5c8aLtPvl8i+yWyV5m2G5FMRdBj49 u8rCLoPi/mON8TDs2U4pbhcdgfBWWvGS6woFp6qrqM0wzXIPLalWsPGK3DUtuFUg onxsClJXMWUvW4k4hbjiqosduLGY/kMeX62Lx1dCj/gktrJpU0GDNR/XbBhHU+hj UT2CL8AfedC4FQekdyJri/rDgPiTMsf8UE0lgtchHMUXH0ztrjaRxMGiIFMm5vCl dJBMGJfCkKR/+U1YrGRQI0tPL8CJKYI8klOEhLoOsCr/WC9p4nvvAzSg4W9mNK5P ni4+KU4f/bj8U0Ap2bUacTpXj6W8VcwJWeuHahVA1Slo+eqXO401hj4W88dQmm9O ZDR5h+6PI6KoL/KL6I4EyOv+sIEtW3s18cEWbSSu3N/CPuhSGTx8d2J201shJXRN uDdMkvbwv48x20pgD2oTkPrZbJHOL3BK5/WPBg7pwpfkoRrBAhY= =Xd5e -----END PGP SIGNATURE----- Merge tag 'nfsd-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This is a light release containing optimizations, code clean-ups, and minor bug fixes.

crypto: ccp: Add the SNP_VLEK_LOAD command
When requesting an attestation report a guest is able to specify whether it wants SNP firmware to sign the report using either a Versioned Chip Endorsement Key (VCEK), which is derived from chip-unique secrets, or a Versioned Loaded Endorsement Key (VLEK) which is obtained from an AMD Key Derivation Service (KDS) and derived from seeds allocated to enrolled cloud service providers (CSPs). For VLEK keys, an SNP_VLEK_LOAD SNP firmware command is used to load them into the system after obtaining them from the KDS. Add a corresponding userspace interface so to allow the loading of VLEK keys into the system. See SEV-SNP Firmware ABI 1.54, SNP_VLEK_LOAD for more details.

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). Drivers ------- - Ethernet high-speed NICs: - Broadcom (bnxt): - increase the max total outstanding PTP TX packets to 4 - add timestamping statistics support - implement netdev_queue_mgmt_ops - support new RSS context API -

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.

Merge branch 'kvm-6.11-sev-attestation' into HEAD
The GHCB 2.0 specification defines 2 GHCB request types to allow SNP guests to send encrypted messages/requests to firmware: SNP Guest Requests and SNP Extended Guest Requests. These encrypted messages are used for things like servicing attestation requests issued by the guest. Implementing support for these is required to be fully GHCB-compliant. For the most part, KVM only needs to handle forwarding these requests to firmware (to be issued via the SNP_GUEST_REQUEST firmware command defined in the SEV-SNP Firmware ABI), and then forwarding the encrypted response to the guest. However, in the case of SNP Extended Guest Requests, the host is also able to provide the certificate data corresponding to the endorsement key used by firmware to sign attestation report requests. This certificate data is provided by userspace because: 1) It allows for different keys/key types to be used for each particular guest with requiring any sort of KVM API to configure the certificate table in advance on a per-guest basis. 2) It provides additional flexibility with how attestation requests might be handled during live migration where the certificate data for source/dest might be different. 3) It allows all synchronization between certificates and firmware/signing key updates to be handled purely by userspace rather than requiring some in-kernel mechanism to facilitate it. [1] To support fetching certificate data from userspace, a new KVM exit type will be needed to handle fetching the certificate from userspace. An attempt to define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this was introduced in v1 of this patchset, but is still being discussed by community, so for now this patchset only implements a stub version of SNP Extended Guest Requests that does not provide certificate data, but is still enough to provide compliance with the GHCB 2.0 spec. |

KVM: SEV: Provide support for SNP_GUEST_REQUEST NAE event
Version 2 of GHCB specification added support for the SNP Guest Request Message NAE event. The event allows for an SEV-SNP guest to make requests to the SEV-SNP firmware through the hypervisor using the SNP_GUEST_REQUEST API defined in the SEV-SNP firmware specification. This is used by guests primarily to request attestation reports from firmware. There are other request types are available as well, but the specifics of what guest requests are being made generally does not affect how they are handled by the hypervisor, which only serves as a proxy for the guest requests and firmware responses. Implement handling for these events. When an SNP Guest Request is issued, the guest will provide its own request/response pages, which could in theory be passed along directly to firmware. However, these pages would need special care: - Both pages are from shared guest memory, so they need to be protected from migration/etc. occurring while firmware reads/writes to them. At a minimum, this requires elevating the ref counts and potentially needing an explicit pinning of the memory. This places additional restrictions on what type of memory backends userspace can use for shared guest memory since there would be some reliance on using refcounted pages. - The response page needs to be switched to Firmware-owned state before the firmware can write to it, which can lead to potential host RMP #PFs if the guest is misbehaved and hands the host a guest page that KVM is writing to for other reasons (e.g. virtio buffers). Both of these issues can be avoided completely by using separately-allocated bounce pages for both the request/response pages and passing those to firmware instead. So that's the approach taken here.

landlock: Clarify documentation for struct landlock_ruleset_attr
The explanation for @handled_access_fs and @handled_access_net has significant overlap and is better explained together. * Explain the commonalities in structure-level documentation. * Clarify some wording and break up longer sentences. * Put emphasis on the word "handled" to make it clearer that "handled" is a term with special meaning in the context of Landlock. I'd like to transfer this wording into the man pages as well.

KVM generic changes for 6.11
- Enable halt poll shrinking by default, as Intel found it to be a clear win. - Setup empty IRQ routing when creating a VM to avoid having to synchronize SRCU when creating a split IRQCHIP on x86. - Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag that arch code can use for hooking both sched_in() and sched_out(). - Take the vCPU @id as an "unsigned long" instead of "u32" to avoid truncating a bogus value from userspace, e.g. to help userspace detect bugs. - Mark a vCPU as preempted if and only if it's scheduled out while in the KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest memory when retrieving guest state during live migration blackout. - A few minor cleanups -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKTobbabEP7vbhhN9OlYIJqCjN/0FAmaRuOYACgkQOlYIJqCj N/1UnQ/8CI5Qfr+/0gzYgtWmtEMczGG+rMNpzD3XVqPjJjXcMcBiQnplnzUVLhha vlPdYVK7vgmEt003XGzV55mik46LHL+DX/v4hI3HEdblfyCeNLW3fKEWVRB44qJe o+YUQwSK42SORUp9oXuQINxhA//U9EnI7CQxlJ8w8wenv5IJKfIGr01DefmfGPAV PKm9t6WLcNqvhZMEyy/zmzM3KVPCJL0NcwI97x6sHxFpQYIDtL0E/VexA4AFqMoT QK7cSDC/2US41Zvem/r/GzM/ucdF6vb9suzZYBohwhxtVhwJe2CDeYQZvtNKJ1U7 GOHPaKL6nBWdZCm/yyWbbX2nstY1lHqxhN3JD0X8wqU5rNcwm2b8Vfyav0Ehc7H+ jVbDTshOx4YJmIgajoKjgM050rdBK59TdfVL+l+AAV5q/TlHocalYtvkEBdGmIDg 2td9UHSime6sp20vQfczUEz4bgrQsh4l2Fa/qU2jFwLievnBw0AvEaMximkSGMJe b8XfjmdTjlOesWAejANKtQolfrq14+1wYw0zZZ8PA+uNVpKdoovmcqSOcaDC9bT8 GO/NFUvoG+lkcvJcIlo1SSl81SmGLosijwxWfGvFAqsgpR3/3l3dYp0QtztoCNJO d3+HnjgYn5o5FwufuTD3eUOXH4AFjG108DH0o25XrIkb2Kymy0o= =BalU -----END PGP SIGNATURE----- Merge tag 'kvm-x86-generic-6.11' of https://github.com/kvm-x86/linux into HEAD KVM generic changes for 6.11 - Enable halt poll shrinking by default, as Intel found it to be a clear win. - Setup empty IRQ routing when creating a VM to avoid having to synchronize SRCU when creating a split IRQCHIP on x86. - Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag that arch code can use for hooking both sched_in() and sched_out(). - Take the vCPU @id as an "unsigned long" instead of "u32" to avoid truncating a bogus value from userspace, e.g. to help userspace detect bugs. - Mark a vCPU as preempted if and only if it's scheduled out while in the KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest memory when retrieving guest state during live migration blackout. - A few minor cleanups |
