The problem is because bpf_arch_text_copy() silently fails to write to the

Update patch_map() to use CONFIG_EXECMEM instead of
CONFIG_STRICT_MODULE_RWX to check for vmalloc addresses.

mseal: wire up mseal syscall
Patch series "Introduce mseal", v10. This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections. In closing, I would like to formally acknowledge the valuable contributions received during the RFC process, which were instrumental in shaping this patch: Jann Horn: raising awareness and providing valuable insights on the destructive madvise operations. Liam R. Howlett: perf optimization. Linus Torvalds: assisting in defining system call signature and scope. Theo de Raadt: sharing the experiences and insight gained from implementing mimmutable() in OpenBSD. MM perf benchmarks ================== This patch adds a loop in the mprotect/munmap/madvise(DONTNEED) to check the VMAs’ sealing flag, so that no partial update can be made, when any segment within the given memory range is sealed. To measure the performance impact of this loop, two tests are developed. [8] The first is measuring the time taken for a particular system call, by using clock_gettime(CLOCK_MONOTONIC). The second is using PERF_COUNT_HW_REF_CPU_CYCLES (exclude user space). Both tests have similar results. The tests have roughly below sequence: for (i = 0; i < 1000, i++) create 1000 mappings (1 page per VMA) start the sampling for (j = 0; j < 1000, j++) mprotect one mapping stop and save the sample delete 1000 mappings calculates all samples. Below tests are performed on Intel(R) Pentium(R) Gold 7505 @ 2.00GHz, 4G memory, Chromebook.

In comparison to mseal, which adds 20-40 ns or 50-100 CPU cycles, the increase from 5.10 to 6.8 is significantly larger, approximately ten times greater for munmap and mprotect. When I discuss the mm performance with Brian Makin, an engineer who worked on performance, it was brought to my attention that such performance benchmarks, which measuring millions of mm syscall in a tight loop, may not accurately reflect real-world scenarios, such as that of a database service. Also this is tested using a single HW and ChromeOS, the data from another HW or distribution might be different. It might be best to take this data with a grain of salt.

tracing: Remove second argument of __assign_str()
The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str().

tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

TIF_FOREIGN_FPSTATE is a 'convenience' flag that should reflect whether
the current CPU holds the most recent user mode FP/SIMD state of the
current task. It combines two conditions:
- whether the current CPU's FP/SIMD state belongs to the task;
- whether that state is the most recent associated with the task (as a
task may have executed on other CPUs as well).
When a task is scheduled in and TIF_KERNEL_FPSTATE is set, it means the
task was in a kernel mode NEON section when it was scheduled out, and so
the kernel mode FP/SIMD state is restored. Since this implies that the
current CPU is *not* holding the most recent user mode FP/SIMD state of
the current task, the TIF_FOREIGN_FPSTATE flag is set too, so that the
user mode FP/SIMD state is reloaded from memory when returning to
userland.
However, the task may be scheduled out after completing the kernel mode
NEON section, but before returning to userland. When this happens, the
TIF_FOREIGN_FPSTATE flag will not be preserved, but will be set as usual
the next time the task is scheduled in, and will be based on the above
conditions.
This means that, rather than setting TIF_FOREIGN_FPSTATE when scheduling
in a task with TIF_KERNEL_FPSTATE set, the underlying state should be
updated so that TIF_FOREIGN_FPSTATE will assume the expected value as a
result.
So instead, call fpsimd_flush_cpu_state(), which takes care of this.

arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY
When CONFIG_DEBUG_BUGVERBOSE=n, we fail to add necessary padding bytes
to bug_table entries, and as a result the last entry in a bug table will
be ignored, potentially leading to an unexpected panic(). All prior
entries in the table will be handled correctly.
The arm64 ABI requires that struct fields of up to 8 bytes are
naturally-aligned, with padding added within a struct such that struct
are suitably aligned within arrays.
When CONFIG_DEBUG_BUGVERPOSE=y, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
signed int file_disp; // 4 bytes
unsigned short line; // 2 bytes
unsigned short flags; // 2 bytes
}
... with 12 bytes total, requiring 4-byte alignment.
When CONFIG_DEBUG_BUGVERBOSE=n, the layout of a bug_entry is:
struct bug_entry {
signed int bug_addr_disp; // 4 bytes
unsigned short flags; // 2 bytes
< implicit padding > // 2 bytes
}
... with 8 bytes total, with 6 bytes of data and 2 bytes of trailing
padding, requiring 4-byte alginment.
When we create a bug_entry in assembly, we align the start of the entry
to 4 bytes, which implicitly handles padding for any prior entries.
However, we do not align the end of the entry, and so when
CONFIG_DEBUG_BUGVERBOSE=n, the final entry lacks the trailing padding
bytes.
For the main kernel image this is not a problem as find_bug() doesn't
depend on the trailing padding bytes when searching for entries:
for (bug = __start___bug_table; bug < __stop___bug_table; ++bug)
if (bugaddr == bug_addr(bug))
return bug;
However for modules, module_bug_finalize() depends on the trailing
bytes when calculating the number of entries:
mod->num_bugs = sechdrs[i].sh_size / sizeof(struct bug_entry);
... and as the last bug_entry lacks the necessary padding bytes, this entry
will not be counted, e.g. in the case of a single entry:
sechdrs[i].sh_size == 6
sizeof(struct bug_entry) == 8;
sechdrs[i].sh_size / sizeof(struct bug_entry) == 0;
Consequently module_find_bug() will miss the last bug_entry when it does:
for (i = 0; i < mod->num_bugs; ++i, ++bug)
if (bugaddr == bug_addr(bug))
goto out;
... which can lead to a kenrel panic due to an unhandled bug.
This can be demonstrated with the following module:
static int __init buginit(void)
{
WARN(1, "hello\n");
return 0;
}
static void __exit bugexit(void)
{
}
module_init(buginit);
module_exit(bugexit);
MODULE_LICENSE("GPL");
... which will trigger a kernel panic when loaded:

ARM:
* Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded. This results in better state tracking, and a smaller vcpu structure. * Add full handling of the ERET/ERETAA/ERETAB instructions in nested virtualisation. The last two instructions also require emulating part of the pointer authentication extension. As a result, the trap handling of pointer authentication has been greatly simplified. * Turn the global (and not very scalable) LPI translation cache into a per-ITS, scalable cache, making non directly injected LPIs much cheaper to make visible to the vcpu. * A batch of pKVM patches, mostly fixes and cleanups, as the upstreaming process seems to be resuming. Fingers crossed! * Allocate PPIs and SGIs outside of the vcpu structure, allowing for smaller EL2 mapping and some flexibility in implementing more or less than 32 private IRQs. * Purge stale mpidr_data if a vcpu is created after the MPIDR map has been created. * Preserve vcpu-specific ID registers across a vcpu reset. * Various minor cleanups and improvements. LoongArch: * Add ParaVirt IPI support. * Add software breakpoint support. * Add mmio trace events support. RISC-V: * Support guest breakpoints using ebreak * Introduce per-VCPU mp_state_lock and reset_cntx_lock * Virtualize SBI PMU snapshot and counter overflow interrupts * New selftests for SBI PMU and Guest ebreak * Some preparatory work for both TDX and SNP page fault handling. This also cleans up the page fault path, so that the priorities of various kinds of fauls (private page, no memory, write to read-only slot, etc.) are easier to follow. x86: * Minimize amount of time that shadow PTEs remain in the special REMOVED_SPTE state. This is a state where the mmu_lock is held for reading but concurrent accesses to the PTE have to spin; shortening its use allows other vCPUs to repopulate the zapped region while the zapper finishes tearing down the old, defunct page tables. * Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field, which is defined by hardware but left for software use. This lets KVM communicate its inability to map GPAs that set bits 51:48 on hosts without 5-level nested page tables. Guest firmware is expected to use the information when mapping BARs; this avoids that they end up at a legal, but unmappable, GPA. * Fixed a bug where KVM would not reject accesses to MSR that aren't supposed to exist given the vCPU model and/or KVM configuration. * As usual, a bunch of code cleanups. x86 (AMD): * Implement a new and improved API to initialize SEV and SEV-ES VMs, which will also be extendable to SEV-SNP. The new API specifies the desired encryption in KVM_CREATE_VM and then separately initializes the VM. The new API also allows customizing the desired set of VMSA features; the features affect the measurement of the VM's initial state, and therefore enabling them cannot be done tout court by the hypervisor. While at it, the new API includes two bugfixes that couldn't be applied to the old one without a flag day in userspace or without affecting the initial measurement. When a SEV-ES VM is created with the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected once the VMSA has been encrypted. Also, the FPU and AVX state will be synchronized and encrypted too. * Support for GHCB version 2 as applicable to SEV-ES guests. This, once more, is only accessible when using the new KVM_SEV_INIT2 flow for initialization of SEV-ES VMs. x86 (Intel): * An initial bunch of prerequisite patches for Intel TDX were merged. They generally don't do anything interesting. The only somewhat user visible change is a new debugging mode that checks that KVM's MMU never triggers a #VE virtualization exception in the guest. * Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to L1, as per the SDM. Generic: * Use vfree() instead of kvfree() for allocations that always use vcalloc() or __vcalloc(). * Remove .change_pte() MMU notifier - the changes to non-KVM code are small and Andrew Morton asked that I also take those through the KVM tree. The callback was only ever implemented by KVM (which was also the original user of MMU notifiers) but it had been nonfunctional ever since calls to set_pte_at_notify were wrapped with invalidate_range_start and invalidate_range_end... in 2012. Selftests: * Enhance the demand paging test to allow for better reporting and stressing of UFFD performance. * Convert the steal time test to generate TAP-friendly output. * Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed time across two different clock domains. * Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT. * Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell script, to play nice with running in a minimal userspace environment. * Allow skipping the RSEQ test's sanity check that the vCPU was able to complete a reasonable number of KVM_RUNs, as the assert can fail on a completely valid setup. If the test is run on a large-ish system that is otherwise idle, and the test isn't affined to a low-ish number of CPUs, the vCPU task can be repeatedly migrated to CPUs that are in deep sleep states, which results in the vCPU having very little net runtime before the next migration due to high wakeup latencies. * Define _GNU_SOURCE for all selftests to fix a warning that was introduced by a change to kselftest_harness.h late in the 6.9 cycle, and because forcing every test to #define _GNU_SOURCE is painful. * Provide a global pseudo-RNG instance for all tests, so that library code can generate random, but determinstic numbers. * Use the global pRNG to randomly force emulation of select writes from guest code on x86, e.g. to help validate KVM's emulation of locked accesses. * Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception handlers at VM creation, instead of forcing tests to manually trigger the related setup. Documentation: * Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmZE878UHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroOukQf+LcvZsWtrC7Wd5K9SQbYXaS4Rk6P6 JHoQW2d0hUN893J2WibEw+l1J/0vn5JumqHXyZgJ7CbaMtXkWWQTwDSDLuURUKpv XNB3Sb17G87NH+s1tOh0tA9h5upbtlHVHvrtIwdbb9+XHgQ6HTL4uk+HdfO/p9fW cWBEZAKoWcCIa99Numv3pmq5vdrvBlNggwBugBS8TH69EKMw+V1Vu1SFkIdNDTQk NJJ28cohoP3wnwlIHaXSmU4RujipPH3Lm/xupyA5MwmzO713eq2yUqV49jzhD5/I MA4Ruvgrdm4wpp89N9lQMyci91u6q7R9iZfMu0tSg2qYI3UPKIdstd8sOA== =2lED -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM updates from Paolo Bonzini: "ARM: - Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded.

Modules changes for v6.10-rc1
Finally something fun. Mike Rapoport does some cleanup to allow us to take out module_alloc() out of modules into a new paint shedded execmem_alloc() and execmem_free() so to make emphasis these helpers are actually used outside of modules. It starts with a no-functional changes API rename / placeholders to then allow architectures to define their requirements into a new shiny struct execmem_info with ranges, and requirements for those ranges. Archs now can intitialize this execmem_info as the last part of mm_core_init() if they have to diverge from the norm. Each range is a known type clearly articulated and spelled out in enum execmem_type. Although a lot of this is major cleanup and prep work for future enhancements an immediate clear gain is we get to enable KPROBES without MODULES now. That is ultimately what motiviated to pick this work up again, now with smaller goal as concrete stepping stone. This has been sitting on linux-next for a little less than a month, a few issues were found already and fixed, in particular an odd mips boot issue. Arch folks reviewed the code too. This is ready for wider exposure and testing. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmZDHfMSHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinfIwP/iFsr89v9BjWdRTqzufuHwjOxvFymWxU BbEpOppRny3CckDU9ag9hLIlUaSL1Bg56Zb+znzp5stKOoiQYMDBvjSYdfybPxW2 mRS6SClMF1ubWbzdysdp5Ld9u8T0MQPCLX+P2pKhZRGi0wjkBf5WEkTje+muJKI3 4vYkXS7bNhuTwRQ+EGfze4+AeleGdQJKDWFY00TW9mZTTBADjfHyYU5o0m9ijf5l 3V/weUznODvjVJStbIF7wEQ845Ae02LN1zXfsloIOuBMhcMju+x8IjPgPbD0KhX2 yA48q7mVWkirYp0L5GSQchtqV1GBiP0NK1xXWEpyx6EqQZ4RJCsQhlhjijoExYBR ylP4bqiGVuE3IN075X0OzGCnmOStuzwssfDmug0sMAZH/MvmOQ21WzZdet2nLMas wwJArHqZsBI9BnBlvH9ZM4Y9f1zC7iR1wULaNGwXLPx34X9PIch8Yk+RElP1kMFQ +YrjOuWPjl63pmSkrkk+Pe2eesMPcPB41M6Q2iCjDlp0iBp63LIx2XISUbTf0ljM EsI4ZQseYpx+BmC7AuQfmXvEOjuXII9z072/artVWcB2u/87ixIprnqZVhcs/spy 73DnXB4ufor2PCCC5Xrb/6kT6G+PzF3VwTbHQ1D+fYZ5n2qdyG+LKxgXbtxsRVTp oUg+Z/AJaCMt =Nsg4 -----END PGP SIGNATURE----- Merge tag 'modules-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull modules updates from Luis Chamberlain: "Finally something fun.

Networking changes for 6.10.
Core & protocols ---------------- - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked, and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code -------------------------------------------- - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter --------- - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF --- - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API ---------- - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling ----------------- - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests.

AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs.

arm64 updates for 6.10
ACPI: * Support for the Firmware ACPI Control Structure (FACS) signature feature which is used to reboot out of hibernation on some systems. Kbuild: * Support for building Flat Image Tree (FIT) images, where the kernel Image is compressed alongside a set of devicetree blobs. Memory management: * Optimisation of our early page-table manipulation for creation of the linear mapping. * Support for userfaultfd write protection, which brings along some nice cleanups to our handling of invalid but present ptes. * Extend our use of range TLBI invalidation at EL1. Perf and PMUs: * Ensure that the 'pmu->parent' pointer is correctly initialised by PMU drivers. * Avoid allocating 'cpumask_t' types on the stack in some PMU drivers. * Fix parsing of the CPU PMU "version" field in assembly code, as it doesn't follow the usual architectural rules. * Add best-effort unwinding support for USER_STACKTRACE * Minor driver fixes and cleanups. Selftests: * Minor cleanups to the arm64 selftests (missing NULL check, unused variable).

Updates for the interrupt subsystem:
- Core code: - Interrupt storm detection for the lockup watchdog: Lockups which are caused by interrupt storms are not easy to debug because there is no information about the events which make the lockup detector trigger. To make this more user friendly, provide an extenstion to interrupt statistics which allows to take snapshots and an interface to retrieve the delta to the snapshot. Use this new mechanism in the watchdog code to do a two stage lockup analysis by taking the snapshot and printing the deltas for the topmost active interrupts on the second trigger. Note: This contains both the interrupt and the watchdog changes as the latter depend on the former obviously. - Avoid summation loops in the /proc/interrupts output and use the global counter when possible - Skip suspended interrupts on CPU hotplug operations to ensure that they are not delivered before the system resumes the device drivers when coming out of suspend. - On CPU hot-unplug interrupts which are affine to the outgoing CPU are migrated to a different CPU in the affinity mask. This can fail when the CPUs have no vectors left. Instead of giving up try to migrate it to any online CPU and thereby breaking the affinity setting in order to prevent a stale device interrupt which targets an offline CPU - The usual small cleanups - Driver code: - Support for the RISCV AIA MSI controller - Make the interrupt allocation for the Loongson PCH controller more flexible to prevent vector exhaustion - The usual set of cleanups and fixes all over the place -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmZBCM0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoeZHEACqMLN3K+1HyWflYtcTHJeYCjZLHS77 2tQeKaaskOA4W6dcGXPxMw5CHqAobHVQQMqgcJxhUdqQiOJnFFnrtCD7JtqM0hWK UORNbyeovuhAo+iJ0fTuS8p63H7vm2GIWwBLWJnOuChYv/6Yyx5Cald1skvyvbzL zePhiiAf5mkdmJMeT5wJSCqEWSRYOXsVAJ/0YAwFG3bKkJH3bmDo6SDJY02sXT5P pjbtD/0hum9wIVT4fNdYleHHQMdBdj9dLlcxXBikHq50mDMw7GxvjKiLcXmoerw3 rEBfVVJp3qpSofpNJZ3HH0ywcF3yUzq04/LPE9Tk2MoQ8NF0GzP8r9Ahke4B7cUj FysWNiAlC2IisEi6th313FZkTLx0zgewdsdEBTLt8eAE9TU0wamRbo99LZ8i/Qr3 hk7jV8DzL+EDQJLgl4p1iPJgA708eW17tbCxLEa15VKVV6P58miohmhx/IfPO2Gx FV1PPehtItsmiK/UoRtUCoFdFsqNQtOE+h8DWLyy8RDmhBqGbn9Ut4euXiQIF+rX WJKPFfslCTR39BrBcZnZeNsgOCN7tEfFRstzjzkey1DaeTGWtxmA5UGhpC2vT74y YyXluvZlgKr4S64ABmcqQj++hQLho0OQAih3uW5YVxt4VxEUcXYMJOsV1AQGpMjF UnewWH5opBQdfw== =jFLf -----END PGP SIGNATURE----- Merge tag 'irq-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull interrupt subsystem updates from Thomas Gleixner: "Core code: - Interrupt storm detection for the lockup watchdog: Lockups which are caused by interrupt storms are not easy to debug because there is no information about the events which make the lockup detector trigger.

arm64: extend execmem_info for generated code allocations
The memory allocations for kprobes and BPF on arm64 can be placed anywhere in vmalloc address space and currently this is implemented with overrides of alloc_insn_page() and bpf_jit_alloc_exec() in arm64. Define EXECMEM_KPROBES and EXECMEM_BPF ranges in arm64::execmem_info and drop overrides of alloc_insn_page() and bpf_jit_alloc_exec().

mm/execmem, arch: convert remaining overrides of module_alloc to execmem
Extend execmem parameters to accommodate more complex overrides of module_alloc() by architectures. This includes specification of a fallback range required by arm, arm64 and powerpc, EXECMEM_MODULE_DATA type required by powerpc, support for allocation of KASAN shadow required by s390 and x86 and support for late initialization of execmem required by arm64. The core implementation of execmem_alloc() takes care of suppressing warnings when the initial allocation fails but there is a fallback range defined.

soc: devicetree updates for 6.10, part 1
The updates this time are a bit smaller than most times, mainly because it is not totally dominated by new Qualcomm hardware support. Instead, we larger than average updates for Rockchips, NXP, Allwinner and TI. The only two new SoCs this time are both from NXP and are minor variants of already supported ones. The updates for aspeed, amlogic and mediatek came a little late, so I'm saving those for part 2 in a few days if everything turns out fine. New machines this time contain: - two Broadcom SoC based wireless routers from Asus - Five allwinner based consumer devices for gaming, set-top-box and eboot reader applications - Three older phones based on Qualcomm chips, plus the more recent Sony Xperia 1 V - 14 industrial and embedded boards based on NXP i.MX6, i.MX8, layerscape and s32g3 SoCs - six rockchips boards including another handheld game console and a few single-board computers On top of these, we have the usual cleanups for dtc warnings and updates to add more features to already merged machines. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmY+daEACgkQYKtH/8kJ UieIXxAAya9WFfjgJrkOCJnn/3+4Q9nr4HzvCaKPfvbw2YH8krxuXTAI5xyeoUNY NMb8qyugi94Xw4Jh3qbAYyvQUXFFNgFTvuTQIGqOBIMSNkPjfghiq45emCr+d1ea 0lsCuu1Mpw62H6038xiyMNJNUFyWjLEoLlLaYqPIZj5/jHiOT1hiKZAB5d3+epzx IhkWEvnSgDo37o6XEtaijFDpu64khdpcWhS4aOt2nJQAR73YYO+jySqEGVwDW4Ht VXEim70ckcj1WLhGjNYakwkDIw2It24vndzcnmLLJMq5k+9mIZ7D3RYPJrKYLcZk /F/hozcYFOxVX0TX+ATwaiKsnUQthvBGEKaaeDTO/VCD87ya6/3FIr7LJezLy4fh t8Vvmgme0JH0kFczWr36YVxdGk6QolkQvNGawTIqPdj5Guj2eSkDHLYIc0HOOps+ 4pDKDLO5MUXrOjtWXYy48zGE+7zF58m3QySwieoJAVF5LbnLuXAevmcL+AjQ+QfK pBTtyDe6hUHxh5vQHSoY05loQ2dELWBxza+G5lNByYMPX4/qzQHcxeZlF7kMm0t5 XE0T0lG/C25QPKQRa1NQ950WtJDoGIWtF0+Kk0qzRP6WbgkX0Wo/NemSmCmVD4IJ PM/nQYCkccwdD5TjyUl0ZiS/LVfd54MXFHqcrTU2zOMC+YryZHM= =SnV4 -----END PGP SIGNATURE----- Merge tag 'soc-dt-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC devicetree updates from Arnd Bergmann: "The updates this time are a bit smaller than most times, mainly because it is not totally dominated by new Qualcomm hardware support.

bpf, arm64: inline bpf_get_smp_processor_id() helper
Inline calls to bpf_get_smp_processor_id() helper in the JIT by emitting a read from struct thread_info. The SP_EL0 system register holds the pointer to the task_struct and thread_info is the first member of this struct. We can read the cpu number from the thread_info.

arm64, bpf: add internal-only MOV instruction to resolve per-CPU addrs
Support an instruction for resolving absolute addresses of per-CPU
data from their per-CPU offsets. This instruction is internal-only and
users are not allowed to use them directly. They will only be used for
internal inlining optimizations for now between BPF verifier and BPF
JITs.

KVM/arm64 updates for Linux 6.10
- Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded. This results in better state tracking, and a smaller vcpu structure. - Add full handling of the ERET/ERETAA/ERETAB instructions in nested virtualisation. The last two instructions also require emulating part of the pointer authentication extension. As a result, the trap handling of pointer authentication has been greattly simplified. - Turn the global (and not very scalable) LPI translation cache into a per-ITS, scalable cache, making non directly injected LPIs much cheaper to make visible to the vcpu. - A batch of pKVM patches, mostly fixes and cleanups, as the upstreaming process seems to be resuming. Fingers crossed! - Allocate PPIs and SGIs outside of the vcpu structure, allowing for smaller EL2 mapping and some flexibility in implementing more or less than 32 private IRQs. - Purge stale mpidr_data if a vcpu is created after the MPIDR map has been created. - Preserve vcpu-specific ID registers across a vcpu reset. - Various minor cleanups and improvements. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmY/PT4ACgkQI9DQutE9 ekNwSA/7BTro0n5gP5/SfSFJeEedigpmHQJtHJk9og0LBzjXZTvYqKpI5J1HnpWE AFsDf3aDRPaSCvI+S14LkkK+TmGtVEXUg8YGytQo08IcO2x6xBT/YjpkVOHy23kq SGgNMPNUH2sycb7hTcz9Z/V0vBeYwFzYEAhmpvtROvmaRd8ZIyt+ofcclwUZZAQ2 SolOXR2d+ynCh8ZCOexqyZ67keikW1NXtW5aNWWFc6S6qhmcWdaWJGDcSyHauFac +YuHjPETJYh7TNpwYTmKclRh1fk/CgA/e+r71Hlgdkg+DGCyVnEZBQxqMi6GTzNC dzy3qhTtRT61SR54q55yMVIC3o6uRSkht+xNg1Nd+UghiqGKAtoYhvGjduodONW2 1Eas6O+vHipu98HgFnkJRPlnF1HR3VunPDwpzIWIZjK0fIXEfrWqCR3nHFaxShOR dniTEPfELguxOtbl3jCZ+KHCIXueysczXFlqQjSDkg/P1l0jKBgpkZzMPY2mpP1y TgjipfSL5gr1GPdbrmh4WznQtn5IYWduKIrdEmSBuru05OmBaCO4geXPUwL4coHd O8TBnXYBTN/z3lORZMSOj9uK8hgU1UWmnOIkdJ4YBBAL8DSS+O+KtCRkHQP0ghl+ whl0q1SWTu4LtOQzN5CUrhq9Tge11erEt888VyJbBJmv8x6qJjE= =CEfD -----END PGP SIGNATURE----- Merge tag 'kvmarm-6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for Linux 6.10 - Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded.

arm64: errata: Add workaround for Arm errata 3194386 and 3312417
Cortex-X4 and Neoverse-V3 suffer from errata whereby an MSR to the SSBS special-purpose register does not affect subsequent speculative instructions, permitting speculative store bypassing for a window of time. This is described in their Software Developer Errata Notice (SDEN) documents: * Cortex-X4 SDEN v8.0, erratum 3194386: https://developer.arm.com/documentation/SDEN-2432808/0800/ * Neoverse-V3 SDEN v6.0, erratum 3312417: https://developer.arm.com/documentation/SDEN-2891958/0600/ To workaround these errata, it is necessary to place a speculation barrier (SB) after MSR to the SSBS special-purpose register. This patch adds the requisite SB after writes to SSBS within the kernel, and hides the presence of SSBS from EL0 such that userspace software which cares about SSBS will manipulate this via prctl(PR_GET_SPECULATION_CTRL, ...).

arm64: Properly clean up iommu-dma remnants
Thanks to the somewhat asymmetrical nature, while removing
iommu_setup_dma_ops() from the arch_setup_dma_ops() flow, I managed to
forget that arm64's teardown path was also specific to iommu-dma. Clean
that up to match, otherwise probe deferral will lead to the arch code
erroneously removing DMA ops set elsewhere.

kbuild: use $(src) instead of $(srctree)/$(src) for source directory
Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for checked-in source files. It is merely a convention without any functional difference. In fact, $(obj) and $(src) are exactly the same, as defined in scripts/Makefile.build: src := $(obj) When the kernel is built in a separate output directory, $(src) does not accurately reflect the source directory location. While Kbuild resolves this discrepancy by specifying VPATH=$(srctree) to search for source files, it does not cover all cases. For example, when adding a header search path for local headers, -I$(srctree)/$(src) is typically passed to the compiler. This introduces inconsistency between upstream and downstream Makefiles because $(src) is used instead of $(srctree)/$(src) for the latter. To address this inconsistency, this commit changes the semantics of $(src) so that it always points to the directory in the source tree. Going forward, the variables used in Makefiles will have the following meanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source tree Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced with $(src).

KVM: arm64: Only reset vCPU-scoped feature ID regs once
The general expecation with feature ID registers is that they're 'reset' exactly once by KVM for the lifetime of a vCPU/VM, such that any userspace changes to the CPU features / identity are honored after a vCPU gets reset (e.g. PSCI_ON). KVM handles what it calls VM-scoped feature ID registers correctly, but feature ID registers local to a vCPU (CLIDR_EL1, MPIDR_EL1) get wiped after every reset. What's especially concerning is that a potentially-changing MPIDR_EL1 breaks MPIDR compression for indexing mpidr_data, as the mask of useful bits to build the index could change. This is absolutely no good. Avoid resetting vCPU feature ID registers more than once.

arm64/mm: Fix pud_user_accessible_page() for PGTABLE_LEVELS <= 2
The recent change to use pud_valid() as part of the implementation of
pud_user_accessible_page() fails to build when PGTABLE_LEVELS <= 2
because pud_valid() is not defined in that case.
Fix this by defining pud_valid() to false for this case. This means that
pud_user_accessible_page() will correctly always return false for this
config.

KVM: arm64: Destroy mpidr_data for 'late' vCPU creation
A particularly annoying userspace could create a vCPU after KVM has
computed mpidr_data for the VM, either by racing against VGIC
initialization or having a userspace irqchip.
In any case, this means mpidr_data no longer fully describes the VM, and
attempts to find the new vCPU with kvm_mpidr_to_vcpu() will fail. The
fix is to discard mpidr_data altogether, as it is only a performance
optimization and not required for correctness. In all likelihood KVM
will recompute the mappings when KVM_RUN is called on the new vCPU.
Note that reads of mpidr_data are not guarded by a lock; promote to RCU
to cope with the possibility of mpidr_data being invalidated at runtime.

bpf, arm64: Add support for lse atomics in bpf_arena
When LSE atomics are available, BPF atomic instructions are implemented as single ARM64 atomic instructions, therefore it is easy to enable these in bpf_arena using the currently available exception handling setup. LL_SC atomics use loops and therefore would need more work to enable in bpf_arena. Enable LSE atomics based instructions in bpf_arena and use the bpf_jit_supports_insn() callback to reject atomics in bpf_arena if LSE atomics are not available. All atomics and arena_atomics selftests are passing: [root@ip-172-31-2-216 bpf]# ./test_progs -a atomics,arena_atomics #3/1 arena_atomics/add:OK #3/2 arena_atomics/sub:OK #3/3 arena_atomics/and:OK #3/4 arena_atomics/or:OK #3/5 arena_atomics/xor:OK #3/6 arena_atomics/cmpxchg:OK #3/7 arena_atomics/xchg:OK #3 arena_atomics:OK #10/1 atomics/add:OK #10/2 atomics/sub:OK #10/3 atomics/and:OK #10/4 atomics/or:OK #10/5 atomics/xor:OK #10/6 atomics/cmpxchg:OK #10/7 atomics/xchg:OK #10 atomics:OK Summary: 2/14 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Puranjay Mohan <puranjay@kernel.org> Link: https://lore.kernel.org/r/20240426161116.441-1-puranjay@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

KVM: arm64: Fix hvhe/nvhe early alias parsing
Booting a kernel with "arm64_sw.hvhe=1 kvm-arm.mode=nvhe" on the command-line results in KVM initialising using hVHE, whereas one might expect the latter option to override the former. Fix this by adding "arm64_sw.hvhe=0" to the alias expansion for "kvm-arm.mode=nvhe".

The card detect pin reference is corrected to solve this problem. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmYtG44VHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FThQQAJvYr5LolVQPL4etFNL1OY/2xC2u gAahfgrXk/IDpJAsnJ2fgZn59A4zuNI+Efvh6iWbMkVhyKgdiTY/VI2Io5iSb0mq NmdWf2ll/aaM7C35Q7nsWB3bERN+GlLXKXJEugJrpct9uzlJYNkawZvyhquxBLc5 MAYXugaD7xzMVliYIyhova1+nzcMfgZld4PzyBDnpXz0GtN7ZyI0XaRa8FcYl5FV ESNHpsIrP0mxFWWJS9XOkBeEGNVN3DH1SS4p73AiJ0LFU4Y5DxmtqeBFPtPB7Gpe AR165n3bAr77gT3cQ8/uo1afCCSV07tSdxhy6ULn1HSiROBIJRZjpb2ly1asMhe6 DjviNcgxtpYHC1xh9ItTt7gojlD6ZdK26M5HoEn5+TyRZ6ZbeAZnw749maZ03mXu pTKUdTg5hgLgGmuiq5lupuKr3YltuXpRe9oGZJxAUlU3MHTxdG8+5oRLYha5qqd3 T8UBYT1fpxknuqAsye7rnE/fhok0QGGhsWTQwYnTh9t/5wbK9/wQwN4fuOwEGwtR 23LDZFMEksVW5sykYmwBFqQ5AzqfyaRU3sMyDA+Pn9XKGvtZ0McPmlrvmPTjQXsp 0q9XU14Ozd/D7mihATLKDija8wdlNRNK7p8U+vxuGzQBArNPWbL8onARpSjhzu7/ b+osswzeX6FbvY1E =+Jm6 -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmY5xQoACgkQYKtH/8kJ UicIQg//YmxeExPEPpfbDtVd3rMaEgy7THE7QMxcRVE0daea4pF+aMD8cmYhGvhk XICNC+Qj8x3ZL2Q0efN5LqJK3fL2CiS5asU0dwhm69nuumygsznkiLW7Dj0zDNoG rZwbx3gPAhJ3dkg8V55ag2D58/1wq/LsmrcR/HSRxBZtOgJLknf3fHNlKP9EfiMO NuJPloUsRoosTetLpC5me3rE9REruGvBYhPPe5AOM2TYkEXttYAsbS0vVdaPxg9t 77O13ASuDLMMcU+mgOnLxzQUNP6+SQKVmkfQecgXS9dfaTs5Ru6x7T1ffbxRrh2r AUSh2TpImg9MU9Mz3345dhR8nriCUxw4KIiud5MF2y2ig4Ho5Kz9bkFiPNNTBkIH OLRRlRpy0YglbZWQ4dfDar0Klzkbe5IFrGZCdWQo/jzt+yNDjhX/ZDx6gqSLHf+T QBRjzjnWXVTz+s36b7vPW+PpmSeZWL0jMOMKekpIp7nXXYj9nHThebq7pETFq0SY e/bAdy/wNTsK51vcMh+5+acMDoXq/pqbhKZfN6QdO7i/ymbh+4mCEi2VcaiH3w3a i+wKBuMy0k5pkjNAWXkUSl1+RyT71+Sz1um4gBezKk5QqSXM1C6yqaX+LJ7IiqnD 8ev1T1CtrcXL3EajYTD7BeU0ryz1hs4Bumk3nOYsgKy/Rd6UcRA= =CCJj -----END PGP SIGNATURE----- Merge tag 'qcom-arm64-fixes-for-6.9-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/fixes One more Qualcomm Arm64 DeviceTree fix for v6.9 On ths SA8155P automotive platform, the wrong gpio controller is defined for the SD-card detect pin, which depending on probe ordering of things cause ethernet to be broken.

mm/arm64: override clear_young_dirty_ptes() batch helper
The per-pte get_and_clear/modify/set approach would result in unfolding/refolding for contpte mappings on arm64. So we need to override clear_young_dirty_ptes() for arm64 to avoid it.

arm64: mm: drop VM_FAULT_BADMAP/VM_FAULT_BADACCESS
Patch series "mm: remove arch's private VM_FAULT_BADMAP/BADACCESS", v2. Directly set SEGV_MAPRR or SEGV_ACCERR for arm/arm64 to remove the last two arch's private vm_fault reasons. This patch (of 2): If bad map or access, directly set si_code to SEGV_MAPRR or SEGV_ACCERR, also set fault to 0 and goto error handling, which make us to drop the arch's special vm fault reason.

arm64: dts: marvell: espressobin-ultra: fix Ethernet Switch unit address
The Espressobin Ultra DTS includes Espressobin DTSI which defines ethernet-switch@1 node. The Ultra DTS overrides "reg" to 3, but that leaves still old unit address which conflicts with the new phy@1 node (W=1 dtc warning): armada-3720-espressobin.dtsi:148.29-203.4: Warning (unique_unit_address_if_enabled): /soc/internal-regs@d0000000/mdio@32004/ethernet-switch@1: duplicate unit-address (also used in node /soc/internal-regs@d0000000/mdio@32004/ethernet-phy@1) Fix this by deleting ethernet-switch@1 node and merging original node with code from Ultra DTS into new ethernet-switch@3.
