Pull landlock updates from Mickaël Salaün: "A Landlock ruleset can now handle two new access rights: LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When handled, the related actions are denied unless explicitly allowed by a Landlock network rule for a specific port. The related patch series has been reviewed for almost two years, it has evolved a lot and we now have reached a decent design, code and testing. The refactored kernel code and the new test helpers also bring the foundation to support more network protocols. Test coverage for security/landlock is 92.4% of 710 lines according to gcc/gcov-13, and it was 93.1% of 597 lines before this series. The decrease in coverage is due to code refactoring to make the ruleset management more generic (i.e. dealing with inodes and ports) that also added new WARN_ON_ONCE() checks not possible to test from user space. syzkaller has been updated accordingly [4], and such patched instance (tailored to Landlock) has been running for a month, covering all the new network-related code [5]" Link: https://lore.kernel.org/r/20231026014751.414649-1-konstantin.meskhidze@huawei.com [1] Link: https://lore.kernel.org/r/CAHC9VhS1wwgH6NNd+cJz4MYogPiRV8NyPDd1yj5SpaxeUB4UVg@mail.gmail.com [2] Link: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next-history.git/commit/?id=c8dc5ee69d3a [3] Link: https://github.com/google/syzkaller/pull/4266 [4] Link: https://storage.googleapis.com/syzbot-assets/82e8608dec36/ci-upstream-linux-next-kasan-gce-root-ab577164.html#security%2flandlock%2fnet.c [5] * tag 'landlock-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux: selftests/landlock: Add tests for FS topology changes with network rules landlock: Document network support samples/landlock: Support TCP restrictions selftests/landlock: Add network tests selftests/landlock: Share enforce_ruleset() helper landlock: Support network rules with TCP bind and connect landlock: Refactor landlock_add_rule() syscall landlock: Refactor layer helpers landlock: Move and rename layer helpers landlock: Refactor merge/inherit_ruleset helpers landlock: Refactor landlock_find_rule/insert_rule helpers landlock: Allow FS topology changes for domains without such rule type landlock: Make ruleset's access masks more generic

Merge tag 'perf-tools-for-v6.7-1-2023-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools Pull perf tools updates from Namhyung Kim: "Build: - Compile BPF programs by default if clang (>= 12.0.1) is available to enable more features like kernel lock contention, off-cpu profiling, kwork, sample filtering and so on. This can be disabled by passing BUILD_BPF_SKEL=0 to make. - Produce better error messages for bison on debug build (make DEBUG=1) by defining YYDEBUG symbol internally. perf record: - Track sideband events (like FORK/MMAP) from all CPUs even if perf record targets a subset of CPUs only (using -C option). Otherwise it may lose some information happened on a CPU out of the target list. - Fix checking raw sched_switch tracepoint argument using system BTF. This affects off-cpu profiling which attaches a BPF program to the raw tracepoint. perf lock contention: - Add --lock-cgroup option to see contention by cgroups. This should be used with BPF only (using -b option). $ sudo perf lock con -ab --lock-cgroup -- sleep 1 contended total wait max wait avg wait cgroup 835 14.06 ms 41.19 us 16.83 us /system.slice/led.service 25 122.38 us 13.77 us 4.89 us / 44 23.73 us 3.87 us 539 ns /user.slice/user-657345.slice/session-c4.scope 1 491 ns 491 ns 491 ns /system.slice/connectd.service - Add -G/--cgroup-filter option to see contention only for given cgroups. This can be useful when you identified a cgroup in the above command and want to investigate more on it. It also works with other output options like -t/--threads and -l/--lock-addr. $ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1 contended total wait max wait avg wait type caller 8 77.11 us 17.98 us 9.64 us spinlock futex_wake+0xc8 2 24.56 us 14.66 us 12.28 us spinlock tick_do_update_jiffies64+0x25 1 4.97 us 4.97 us 4.97 us spinlock futex_q_lock+0x2a - Use per-cpu array for better spinlock tracking. This is to improve performance of the BPF program and to avoid nested contention on a lock in the BPF hash map. - Update callstack check for PowerPC. To find a representative caller of a lock, it needs to look up the call stacks. It ends the lookup when it sees 0 in the call stack buffer. However, PowerPC call stacks can have 0 values in the beginning so skip them when it expects valid call stacks after. perf kwork: - Support 'sched' class (for -k option) so that it can see task scheduling event (using sched_switch tracepoint) as well as irq and workqueue items. - Add perf kwork top subcommand to show more accurate cpu utilization with sched class above. It works both with a recorded data (using perf kwork record command) and BPF (using -b option). Unlike perf top command, it does not support interactive mode (yet). $ sudo perf kwork top -b -k sched Starting trace, Hit <Ctrl+C> to stop and report ^C Total : 160702.425 ms, 8 cpus %Cpu(s): 36.00% id, 0.00% hi, 0.00% si %Cpu0 [|||||||||||||||||| 61.66%] %Cpu1 [|||||||||||||||||| 61.27%] %Cpu2 [||||||||||||||||||| 66.40%] %Cpu3 [|||||||||||||||||| 61.28%] %Cpu4 [|||||||||||||||||| 61.82%] %Cpu5 [||||||||||||||||||||||| 77.41%] %Cpu6 [|||||||||||||||||| 61.73%] %Cpu7 [|||||||||||||||||| 63.25%] PID SPID %CPU RUNTIME COMMMAND ------------------------------------------------------------- 0 0 38.72 8089.463 ms [swapper/1] 0 0 38.71 8084.547 ms [swapper/3] 0 0 38.33 8007.532 ms [swapper/0] 0 0 38.26 7992.985 ms [swapper/6] 0 0 38.17 7971.865 ms [swapper/4] 0 0 36.74 7447.765 ms [swapper/7] 0 0 33.59 6486.942 ms [swapper/2] 0 0 22.58 3771.268 ms [swapper/5] 9545 9351 2.48 447.136 ms sched-messaging 9574 9351 2.09 418.583 ms sched-messaging 9724 9351 2.05 372.407 ms sched-messaging 9531 9351 2.01 368.804 ms sched-messaging 9512 9351 2.00 362.250 ms sched-messaging 9514 9351 1.95 357.767 ms sched-messaging 9538 9351 1.86 384.476 ms sched-messaging 9712 9351 1.84 386.490 ms sched-messaging 9723 9351 1.83 380.021 ms sched-messaging 9722 9351 1.82 382.738 ms sched-messaging 9517 9351 1.81 354.794 ms sched-messaging 9559 9351 1.79 344.305 ms sched-messaging 9725 9351 1.77 365.315 ms sched-messaging <SNIP> - Add hard/soft-irq statistics to perf kwork top.

The pipe bench is good to measure context switch overhead. With this option, it puts the reader and writer tasks in separate cgroups to enforce context switch between two different cgroups. Also it needs to set CPU affinity of the tasks in a CPU to accurately measure the impact of cgroup context switches. $ sudo perf stat -e context-switches,cgroup-switches -- \ > taskset -c 0 perf bench sched pipe -l 100000 # Running 'sched/pipe' benchmark: # Executed 100000 pipe operations between two processes Total time: 0.307 [sec] 3.078180 usecs/op 324867 ops/sec Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000': 200,026 context-switches 63 cgroup-switches 0.321637922 seconds time elapsed You can see small number of cgroup-switches because both write and read tasks are in the same cgroup. $ sudo mkdir /sys/fs/cgroup/{AAA,BBB} $ sudo perf stat -e context-switches,cgroup-switches -- \ > taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB # Running 'sched/pipe' benchmark: # Executed 100000 pipe operations between two processes Total time: 0.351 [sec] 3.512990 usecs/op 284657 ops/sec Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB': 200,020 context-switches 200,019 cgroup-switches 0.365034567 seconds time elapsed Now context-switches and cgroup-switches are almost same. And you can see the pipe operation took little more. - Kill child processes when perf bench sched messaging exited abnormally. Otherwise it'd leave the child doing unnecessary work. perf test: - Fix various shellcheck issues on the tests written in shell script. - Skip tests when condition is not satisfied: - object code reading test for non-text section addresses. - CoreSight test if cs_etm// event is not available. - lock contention test if not enough CPUs. Event parsing: - Make PMU alias name loading lazy to reduce the startup time in the event parsing code for perf record, stat and others in the general case. - Lazily compute PMU default config. In the same sense, delay PMU initialization until it's really needed to reduce the startup cost. - Fix event term values that are raw events. The event specification can have several terms including event name. But sometimes it clashes with raw event encoding which starts with 'r' and has hex-digits. For example, an event named 'read' should be processed as a normal event but it was mis-treated as a raw encoding and caused a failure. $ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1 event syntax error: '..nning/event=read/' \___ parser error Run 'perf list' for a list of valid events Usage: perf stat [<options>] [<command>] -e, --event <event> event selector. use 'perf list' to list available events Event metrics: - Add "Compat" regex to match event with multiple identifiers. - Usual updates for Intel, Power10, Arm telemetry/CMN and AmpereOne. Misc: - Assorted memory leak fixes and footprint reduction. - Add "bpf_skeletons" to perf version --build-options so that users can check whether their perf tools have BPF support easily. - Fix unaligned access in Intel-PT packet decoder found by undefined-behavior sanitizer. - Avoid frequency mode for the dummy event. Surprisingly it'd impact kernel timer tick handler performance by force iterating all PMU events. - Update bash shell completion for events and metrics" * tag 'perf-tools-for-v6.7-1-2023-11-01' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools: (187 commits) perf vendor events intel: Update tsx_cycles_per_elision metrics perf vendor events intel: Update bonnell version number to v5 perf vendor events intel: Update westmereex events to v4 perf vendor events intel: Update meteorlake events to v1.06 perf vendor events intel: Update knightslanding events to v16 perf vendor events intel: Add typo fix for ivybridge FP perf vendor events intel: Update a spelling in haswell/haswellx perf vendor events intel: Update emeraldrapids to v1.01 perf vendor events intel: Update alderlake/alderlake events to v1.23 perf build: Disable BPF skeletons if clang version is < 12.0.1 perf callchain: Fix spelling mistake "statisitcs" -> "statistics" perf report: Fix spelling mistake "heirachy" -> "hierarchy" perf python: Fix binding linkage due to rename and move of evsel__increase_rlimit() perf tests: test_arm_coresight: Simplify source iteration perf vendor events intel: Add tigerlake two metrics perf vendor events intel: Add broadwellde two metrics perf vendor events intel: Fix broadwellde tma_info_system_dram_bw_use metric perf mem_info: Add and use map_symbol__exit and addr_map_symbol__exit perf callchain: Minor layout changes to callchain_list perf callchain: Make brtype_stat in callchain_list optional ...

Pull tracing updates from Steven Rostedt: - Remove eventfs_file descriptor This is the biggest change, and the second part of making eventfs create its files dynamically. In 6.6 the first part was added, and that maintained a one to one mapping between eventfs meta descriptors and the directories and file inodes and dentries that were dynamically created. The directories were represented by a eventfs_inode and the files were represented by a eventfs_file. In v6.7 the eventfs_file is removed. As all events have the same directory make up (sched_switch has an "enable", "id", "format", etc files), the handing of what files are underneath each leaf eventfs directory is moved back to the tracing subsystem via a callback. When an event is added to the eventfs, it registers an array of evenfs_entry's. These hold the names of the files and the callbacks to call when the file is referenced. The callback gets the name so that the same callback may be used by multiple files. The callback then supplies the filesystem_operations structure needed to create this file. This has brought the memory footprint of creating multiple eventfs instances down by 2 megs each! - User events now has persistent events that are not associated to a single processes. These are privileged events that hang around even if no process is attached to them - Clean up of seq_buf There's talk about using seq_buf more to replace strscpy() and friends. But this also requires some minor modifications of seq_buf to be able to do this - Expand instance ring buffers individually Currently if boot up creates an instance, and a trace event is enabled on that instance, the ring buffer for that instance and the top level ring buffer are expanded (1.4 MB per CPU). This wastes memory as this happens when nothing is using the top level instance - Other minor clean ups and fixes * tag 'trace-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (34 commits) seq_buf: Export seq_buf_puts() seq_buf: Export seq_buf_putc() eventfs: Use simple_recursive_removal() to clean up dentries eventfs: Remove special processing of dput() of events directory eventfs: Delete eventfs_inode when the last dentry is freed eventfs: Hold eventfs_mutex when calling callback functions eventfs: Save ownership and mode eventfs: Test for ei->is_freed when accessing ei->dentry eventfs: Have a free_ei() that just frees the eventfs_inode eventfs: Remove "is_freed" union with rcu head eventfs: Fix kerneldoc of eventfs_remove_rec() tracing: Have the user copy of synthetic event address use correct context eventfs: Remove extra dget() in eventfs_create_events_dir() tracing: Have trace_event_file have ref counters seq_buf: Introduce DECLARE_SEQ_BUF and seq_buf_str() eventfs: Fix typo in eventfs_inode union comment eventfs: Fix WARN_ON() in create_file_dentry() powerpc: Remove initialisation of readpos tracing/histograms: Simplify last_cmd_set() seq_buf: fix a misleading comment ...

Pull printk updates from Petr Mladek: - Another preparation step for introducing printk kthreads. The main piece is a per-console lock with several features: - Support three priorities: normal, emergency, and panic. They will be defined by a context where the lock is taken. A context with a higher priority is allowed to take over the lock from a context with a lower one. The plan is to use the emergency context for Oops and WARN() messages, and also by watchdogs. The panic() context will be used on panic CPU. - The owner might enter/exit regions where it is not safe to take over the lock. It allows the take over the lock a safe way in the middle of a message. For example, serial drivers emit characters one by one. And the serial port is in a safe state in between. Only the final console_flush_in_panic() will be allowed to take over the lock even in the unsafe state (last chance, pray, and hope). - A higher priority context might busy wait with a timeout. The current owner is informed about the waiter and releases the lock on exit from the unsafe state. - The new lock is safe even in atomic contexts, including NMI. Another change is a safe manipulation of per-console sequence number counter under the new lock. - simple_strntoull() micro-optimization - Reduce pr_flush() pooling time. - Calm down false warning about possible buffer invalid access to console buffers when CONFIG_PRINTK is disabled. [ .. and Thomas Gleixner wants to point out that while several of the commits are attributed to him, he only authored the early versions of said commits, and that John Ogness and Petr Mladek have been the ones who sorted out the details and really should be those who get the credit - Linus ] * tag 'printk-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: vsprintf: uninline simple_strntoull(), reorder arguments printk: printk: Remove unnecessary statements＇len = 0;＇ printk: Reduce pr_flush() pooling time printk: fix illegal pbufs access for !CONFIG_PRINTK printk: nbcon: Allow drivers to mark unsafe regions and check state printk: nbcon: Add emit function and callback function for atomic printing printk: nbcon: Add sequence handling printk: nbcon: Add ownership state functions printk: nbcon: Add buffer management printk: Make static printk buffers available to nbcon printk: nbcon: Add acquire/release logic printk: Add non-BKL (nbcon) console basic infrastructure -

Pull kvm updates from Paolo Bonzini: "ARM: - Generalized infrastructure for 'writable' ID registers, effectively allowing userspace to opt-out of certain vCPU features for its guest - Optimization for vSGI injection, opportunistically compressing MPIDR to vCPU mapping into a table - Improvements to KVM's PMU emulation, allowing userspace to select the number of PMCs available to a VM - Guest support for memory operation instructions (FEAT_MOPS) - Cleanups to handling feature flags in KVM_ARM_VCPU_INIT, squashing bugs and getting rid of useless code - Changes to the way the SMCCC filter is constructed, avoiding wasted memory allocations when not in use - Load the stage-2 MMU context at vcpu_load() for VHE systems, reducing the overhead of errata mitigations - Miscellaneous kernel and selftest fixes LoongArch: - New architecture for kvm. The hardware uses the same model as x86, s390 and RISC-V, where guest/host mode is orthogonal to supervisor/user mode. The virtualization extensions are very similar to MIPS, therefore the code also has some similarities but it's been cleaned up to avoid some of the historical bogosities that are found in arch/mips. The kernel emulates MMU, timer and CSR accesses, while interrupt controllers are only emulated in userspace, at least for now. RISC-V: - Support for the Smstateen and Zicond extensions - Support for virtualizing senvcfg - Support for virtualized SBI debug console (DBCN) S390: - Nested page table management can be monitored through tracepoints and statistics x86: - Fix incorrect handling of VMX posted interrupt descriptor in KVM_SET_LAPIC, which could result in a dropped timer IRQ - Avoid WARN on systems with Intel IPI virtualization - Add CONFIG_KVM_MAX_NR_VCPUS, to allow supporting up to 4096 vCPUs without forcing more common use cases to eat the extra memory overhead. - Add virtualization support for AMD SRSO mitigation (IBPB_BRTYPE and SBPB, aka Selective Branch Predictor Barrier). - Fix a bug where restoring a vCPU snapshot that was taken within 1 second of creating the original vCPU would cause KVM to try to synchronize the vCPU's TSC and thus clobber the correct TSC being set by userspace. - Compute guest wall clock using a single TSC read to avoid generating an inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads. - "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain about a "Firmware Bug" if the bit isn't set for select F/M/S combos. Likewise "virtualize" (ignore) MSR_AMD64_TW_CFG to appease Windows Server 2022. - Don't apply side effects to Hyper-V's synthetic timer on writes from userspace to fix an issue where the auto-enable behavior can trigger spurious interrupts, i.e. do auto-enabling only for guest writes. - Remove an unnecessary kick of all vCPUs when synchronizing the dirty log without PML enabled. - Advertise "support" for non-serializing FS/GS base MSR writes as appropriate. - Harden the fast page fault path to guard against encountering an invalid root when walking SPTEs. - Omit "struct kvm_vcpu_xen" entirely when CONFIG_KVM_XEN=n. - Use the fast path directly from the timer callback when delivering Xen timer events, instead of waiting for the next iteration of the run loop. This was not done so far because previously proposed code had races, but now care is taken to stop the hrtimer at critical points such as restarting the timer or saving the timer information for userspace. - Follow the lead of upstream Xen and ignore the VCPU_SSHOTTMR_future flag. - Optimize injection of PMU interrupts that are simultaneous with NMIs. - Usual handful of fixes for typos and other warts. x86 - MTRR/PAT fixes and optimizations: - Clean up code that deals with honoring guest MTRRs when the VM has non-coherent DMA and host MTRRs are ignored, i.e. EPT is enabled. - Zap EPT entries when non-coherent DMA assignment stops/start to prevent using stale entries with the wrong memtype. - Don't ignore guest PAT for CR0.CD=1 && KVM_X86_QUIRK_CD_NW_CLEARED=y This was done as a workaround for virtual machine BIOSes that did not bother to clear CR0.CD (because ancient KVM/QEMU did not bother to set it, in turn), and there's zero reason to extend the quirk to also ignore guest PAT. x86 - SEV fixes: - Report KVM_EXIT_SHUTDOWN instead of EINVAL if KVM intercepts SHUTDOWN while running an SEV-ES guest. - Clean up the recognition of emulation failures on SEV guests, when KVM would like to "skip" the instruction but it had already been partially emulated. This makes it possible to drop a hack that second guessed the (insufficient) information provided by the emulator, and just do the right thing.

Pull sh updates from John Paul Adrian Glaubitz: "While the previously announced patch series for converting arch/sh to device trees is not yet ready for inclusion to mainline and therefore didn't make it for this pull request, there are still a small number changes for v6.7 which include one platform (board plus CPU and driver code) removal plus two fixes. The removal sent in by Arnd Bergmann concerns the microdev board which was an early SuperH prototype board that was never used in production. With the board removed, we were able to drop the now unused code for the SH4-202 CPU and well as the driver code for the superhyway bus and a custom implementation for ioport_map() and ioport_unmap() which will allow us to simplify ioport handling in the future. Another patch set by Geert Uytterhoeven revives SuperH BIOS earlyprintk support which got accidentally disabled in e76fe574 ("sh: Remove old early serial console code V2"), the second patch in the series updates the documentation. Finally, a patch by Masami Hiramatsu fixes a regression reported by the kernel test robot which uncovered that arch/sh is not implementing arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local() instead" * tag 'sh-for-v6.7-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux: locking/atomic: sh: Use generic_cmpxchg_local for arch_cmpxchg_local() Documentation: kernel-parameters: Add earlyprintk=bios on SH sh: bios: Revive earlyprintk support sh: machvec: Remove custom ioport_{un,}map() sh: Remove superhyway bus support sh: Remove unused SH4-202 support sh: Remove stale microdev board

We consistently switched from kmalloc() to vmalloc() in module decompression to prevent potential memory allocation failures with large modules, however vmalloc() is not as memory-efficient and fast as kmalloc(). Since we don't know in general the size of the workspace required by the decompression algorithm, it is more reasonable to use kvmalloc() consistently, also considering that we don't have special memory requirements here.
