The main changes are: 1) Fix a BPF verifier issue in precision tracking for BPF_ALU | BPF_TO_BE | BPF_END where the source register was incorrectly marked as precise, from Shung-Hsi Yu. 2) Fix a concurrency issue in bpf_timer where the former could still have been alive after an application releases or unpins the map, from Hou Tao. 3) Fix a BPF verifier issue where immediates are incorrectly cast to u32 before being spilled and therefore losing sign information, from Hao Sun. 4) Fix a misplaced BPF_TRACE_ITER in check_css_task_iter_allowlist which incorrectly compared bpf_prog_type with bpf_attach_type, from Chuyi Zhou. 5) Add __bpf_hook_{start,end} as well as __bpf_kfunc_{start,end}_defs macros, migrate all BPF-related __diag callsites over to it, and add a new __diag_ignore_all for -Wmissing-declarations to the macros to address recent build warnings, from Dave Marchevsky. 6) Fix broken BPF selftest build of xdp_hw_metadata test on architectures where char is not signed, from Björn Töpel. 7) Fix test_maps selftest to properly use LIBBPF_OPTS() macro to initialize the bpf_map_create_opts, from Andrii Nakryiko. 8) Fix bpffs selftest to avoid unmounting /sys/kernel/debug as it may have been mounted and used by other applications already, from Manu Bretelle. 9) Fix a build issue without CONFIG_CGROUPS wrt css_task open-coded iterators, from Matthieu Baerts. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf: selftests/bpf: get trusted cgrp from bpf_iter__cgroup directly bpf: Let verifier consider {task,cgroup} is trusted in bpf_iter_reg selftests/bpf: Fix broken build where char is unsigned selftests/bpf: precision tracking test for BPF_NEG and BPF_END bpf: Fix precision tracking for BPF_ALU | BPF_TO_BE | BPF_END selftests/bpf: Add test for using css_task iter in sleepable progs selftests/bpf: Add tests for css_task iter combining with cgroup iter bpf: Relax allowlist for css_task iter selftests/bpf: fix test_maps' use of bpf_map_create_opts bpf: Check map->usercnt after timer->timer is assigned bpf: Add __bpf_hook_{start,end} macros bpf: Add __bpf_kfunc_{start,end}_defs macros selftests/bpf: fix test_bpffs selftests/bpf: Add test for immediate spilled to stack bpf: Fix check_stack_write_fixed_off() to correctly spill imm bpf: fix compilation error without CGROUPS ==================== Link: https://lore.kernel.org/r/20231108132448.1970-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

This required some enlightenment of the PCIe AER core to workaround the fact that current generation RCH (Restricted CXL Host) platforms physically hide topology details and registers via a mechanism called RCRB (Root Complex Register Block). The next major highlight is reworks to address bugs in parsing region configurations for next generation VH (Virtual Host) topologies. The old broken algorithm is replaced with a simpler one that significantly increases the number of region configurations supported by Linux. This is again relevant for error handling so that forward and reverse address translation of memory errors can be carried out by Linux for memory regions instantiated by platform firmware. As for other cross-tree work, the ACPI table parsing code has been refactored for reuse parsing the "CDAT" structure which is an ACPI-like data structure that is reported by CXL devices. That work is in preparation for v6.8 support for CXL QoS. Think of this as dynamic generation of NUMA node topology information generated by Linux rather than platform firmware. Lastly, a number of internal object lifetime issues have been resolved along with misc. fixes and feature updates (decoders_committed sysfs ABI).

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.

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 |

perf tools changes for v6.7
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. It 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.

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.

Tracing updates for v6.7:
- 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 a 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. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZUMrBBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6quzVAQCed/kPM7X9j2QZamJVDruMf2CmVxpu /TOvKvSKV584GgEAxLntf5VKx1Q98bc68y3Zkg+OCi8jSgORos1ROmURhws= =iIgb -----END PGP SIGNATURE----- Merge tag 'trace-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 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.

selftests: pmtu.sh: fix result checking
In the PMTU test, when all previous tests are skipped and the new test
passes, the exit code is set to 0. However, the current check mistakenly
treats this as an assignment, causing the check to pass every time.
Consequently, regardless of how many tests have failed, if the latest test
passes, the PMTU test will report a pass.

Many singleton patches against the MM code. The patch series which are
included in this merge do the following: - Kemeng Shi has contributed some compation maintenance work in the series "Fixes and cleanups to compaction". - Joel Fernandes has a patchset ("Optimize mremap during mutual alignment within PMD") which fixes an obscure issue with mremap()'s pagetable handling during a subsequent exec(), based upon an implementation which Linus suggested. - More DAMON/DAMOS maintenance and feature work from SeongJae Park i the following patch series: mm/damon: misc fixups for documents, comments and its tracepoint mm/damon: add a tracepoint for damos apply target regions mm/damon: provide pseudo-moving sum based access rate mm/damon: implement DAMOS apply intervals mm/damon/core-test: Fix memory leaks in core-test mm/damon/sysfs-schemes: Do DAMOS tried regions update for only one apply interval - In the series "Do not try to access unaccepted memory" Adrian Hunter provides some fixups for the recently-added "unaccepted memory' feature. To increase the feature's checking coverage. "Plug a few gaps where RAM is exposed without checking if it is unaccepted memory". - In the series "cleanups for lockless slab shrink" Qi Zheng has done some maintenance work which is preparation for the lockless slab shrinking code. - Qi Zheng has redone the earlier (and reverted) attempt to make slab shrinking lockless in the series "use refcount+RCU method to implement lockless slab shrink". - David Hildenbrand contributes some maintenance work for the rmap code in the series "Anon rmap cleanups". - Kefeng Wang does more folio conversions and some maintenance work in the migration code.

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. 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.

Other than that, there have little change wrt API, rather lots of driver-specific updates and fixes. Some highlight below: ASoC: - Standardization of API prefix - GPIO API usage improvements - Support for HDA patches - Lots of work on SOF, including crash dump support - Fixes for noise when stopping some Sounwire CODECs - Support for AMD platforms with es83xx, AMD ACP 6.3 and 7.0, Awinc AT87390 and AW88399, many Intel platforms, many Mediatek platforms, Qualcomm SM6115 and SC7180 platforms, Richtek RTQ9128 and Texas Instruments TAS575x HD-audio and USB-audio: - Deferred probe support of audio component binding - More fixes and enhancements for Cirrus subcodecs - USB Scarlett2 mixer and McIntosh DSD quirk Others: - More enhancement of snd-aloop driver - Update MAINTAINERS entry for linux-sound mailing list -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmVDqXcOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE+PbhAAsmiOxjXpCNVGbhy9tR+UB9p6gCIzFv5RQQIc 0DzqnqssbJt86jtFMrv0VC6BNfnwcyBVzKxWinKz861xXiM9SRU5vTirUES3Cil/ sZaQYC9ppTrZm3q2EGF4eGC349oZGzuLzk1EkEVPfNHiELwcO4R1NZbtgWKIc8LE bNz8RT3FyxHAv+5juW5suGs0Bq4Mwa9z+eM8xEPwxPL3gpIAb5EapIesHEgaa893 w3jYwKRHCDq0ADtXIY9xI3ypqenfbeTge4nuBnw354sPRVdZInrRfCNkTJojb+tp 5Pc2gpFmTUGy6T2wG6QP23VgeV14BJHrQD3Z1Wh2aQ8V+ARa92XvY1Xeg4vJ+NE0 yhvlh028GjKrMIvhl7mmepV9mia2zA1TluqlzKEla3B5lIj0E1zvMA+vCzNAz3Ro lV2Q0dpJ3ENQ9ahGF/d37u3glrqXxISlG9uTGdY0UcF7U9Iyxb0jEnhQYl05b+zR Oaw/HApuvIUj4cdJWEYf0AnTTqeE8KSZ3wUlPPyuQAdAusCaQFMciWeO0EeLqEId KR/rbnSgVKS3zHLdNw5A67Sv36E9OG/E+EiJ6Tet15a69yq2Oyv4pwMMwbqsvBG5 8kNbtBFGxOHnCrZgM6VV2/g3BP/IwyIFd5kkS2q13FXBTYRpY01dQDjHlmspasNK hYH69AA= =2/dI -----END PGP SIGNATURE----- Merge tag 'sound-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "Most of changes at this time are for ASoC, spread over ASoC core and drivers due to the API prefix standardization.

bpf: Relax allowlist for css_task iter
The newly added open-coded css_task iter would try to hold the global
css_set_lock in bpf_iter_css_task_new, so the bpf side has to be careful in
where it allows to use this iter. The mainly concern is dead locking on
css_set_lock. check_css_task_iter_allowlist() in verifier enforced css_task
can only be used in bpf_lsm hooks and sleepable bpf_iter.
This patch relax the allowlist for css_task iter. Any lsm and any iter
(even non-sleepable) and any sleepable are safe since they would not hold
the css_set_lock before entering BPF progs context.
This patch also fixes the misused BPF_TRACE_ITER in
check_css_task_iter_allowlist which compared bpf_prog_type with
bpf_attach_type.

bpf: Add __bpf_hook_{start,end} macros
Not all uses of __diag_ignore_all(...) in BPF-related code in order to suppress warnings are wrapping kfunc definitions. Some "hook point" definitions - small functions meant to be used as attach points for fentry and similar BPF progs - need to suppress -Wmissing-declarations. We could use __bpf_kfunc_{start,end}_defs added in the previous patch in such cases, but this might be confusing to someone unfamiliar with BPF internals. Instead, this patch adds __bpf_hook_{start,end} macros, currently having the same effect as __bpf_kfunc_{start,end}_defs, then uses them to suppress warnings for two hook points in the kernel itself and some bpf_testmod hook points as well.

selftests/bpf: fix test_bpffs
Currently this tests tries to umount /sys/kernel/debug (TDIR) but the system it is running on may have mounts below. For example, danobi/vmtest [0] VMs have mount -t tracefs tracefs /sys/kernel/debug/tracing as part of their init. This change instead creates a "random" directory under /tmp and uses this as TDIR. If the directory already exists, ignore the error and keep moving on.

This can be used to generate a record of what memory is being dirtied by DMA activities during a VM migration process. A VMM like qemu will combine the IOMMU dirty bits with the CPU's dirty log to determine what memory to transfer. VFIO already has a DMA dirty tracking framework that requires PCI devices to implement tracking HW internally. The iommufd version provides an alternative that the VMM can select, if available. The two are designed to have very similar APIs. - Userspace controlled attributes for hardware page tables (HWPT/iommu_domain). There are currently a few generic attributes for HWPTs (support dirty tracking, and parent of a nest). This is an entry point for the userspace iommu driver to control the HW in detail. - Nested translation support for HWPTs. This is a 2D translation scheme similar to the CPU where a DMA goes through a first stage to determine an intermediate address which is then translated trough a second stage to a physical address. Like for CPU translation the first stage table would exist in VM controlled memory and the second stage is in the kernel and matches the VM's guest to physical map. As every IOMMU has a unique set of parameter to describe the S1 IO page table and its associated parameters the userspace IOMMU driver has to marshal the information into the correct format. This is 1/3 of the feature, it allows creating the nested translation and binding it to VFIO devices, however the API to support IOTLB and ATC invalidation of the stage 1 io page table, and forwarding of IO faults are still in progress. The series includes AMD and Intel support for dirty tracking. Intel support for nested translation. Along the way are a number of internal items: - New iommu core items: ops->domain_alloc_user(), ops->set_dirty_tracking, ops->read_and_clear_dirty(), IOMMU_DOMAIN_NESTED, and iommu_copy_struct_from_user - UAF fix in iopt_area_split() - Spelling fixes and some test suite improvement -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZUDu2wAKCRCFwuHvBreF YcdeAQDaBmjyGLrRIlzPyohF6FrombyWo2512n51Hs8IHR4IvQEA3oRNgQ2tsJRr 1UPuOqnOD5T/oVX6AkUPRBwanCUQwwM= =nyJ3 -----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: "This brings three new iommufd capabilities: - Dirty tracking for DMA.

selftests: add a sanity check for zswap
We recently encountered a bug that makes all zswap store attempt fail. Specifically, after: "141fdeececb3 mm/zswap: delay the initialization of zswap" if we build a kernel with zswap disabled by default, then enabled after the swapfile is set up, the zswap tree will not be initialized. As a result, all zswap store calls will be short-circuited. We have to perform another swapon to get zswap working properly again. Fortunately, this issue has since been fixed by the patch that kills frontswap: "42c06a0e8ebe mm: kill frontswap" which performs zswap_swapon() unconditionally, i.e always initializing the zswap tree. This test add a sanity check that ensure zswap storing works as intended.
