[PATCH bpf-next v2 0/2] selftests: bpf: Migrate test_xdp_meta.sh to test_progs

by Bastien Curutchet

Hi all, This patch series continues the work to migrate the script tests into prog_tests. test_xdp_meta.sh uses the BPF programs defined in progs/test_xdp_meta.c to do a simple XDP/TC functional test that checks the metadata allocation performed by the bpf_xdp_adjust_meta() helper. This is already partly covered by two tests under prog_tests/: - xdp_context_test_run.c uses bpf_prog_test_run_opts() to verify the validity of the xdp_md context after a call to bpf_xdp_adjust_meta() - xdp_metadata.c ensures that these meta-data can be exchanged through an AF_XDP socket. However test_xdp_meta.sh also verifies that the meta-data initialized in the struct xdp_md is forwarded to the struct __sk_buff used by BPF programs at 'TC level'. To cover this, I add a test case in xdp_context_test_run.c that uses the same BPF programs from progs/test_xdp_meta.c. --- Changes in v2: - Add missing close_netns() - Use a unique 'close' label - Link to v1: https://lore.kernel.org/r/20241206-xdp_meta-v1-0-5c150618f6e9@bootlin.com --- Bastien Curutchet (2): selftests/bpf: test_xdp_meta: Rename BPF sections selftests/bpf: Migrate test_xdp_meta.sh into xdp_context_test_run.c tools/testing/selftests/bpf/Makefile | 1 - .../bpf/prog_tests/xdp_context_test_run.c | 87 ++++++++++++++++++++++ tools/testing/selftests/bpf/progs/test_xdp_meta.c | 4 +- tools/testing/selftests/bpf/test_xdp_meta.sh | 58 --------------- 4 files changed, 89 insertions(+), 61 deletions(-) --- base-commit: 0c30734c4f35c4784d3d3ca1bb89d9779045878c change-id: 20241203-xdp_meta-868307cd0e03 Best regards, -- Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com>

[PATCH v7 0/2] selftests/resctrl: SNC kernel support discovery

by Maciej Wieczor-Retman

Changes v7: - Include fallthrough in resctrlfs.c. - Check fp after opening empty cpus file. - Correct a comment and merge strings in snprintf(). Changes v6: - Rebase onto latest kselftest-next. - Looking at the two patches with a fresh eye decided to make a split along the lines of: - Patch 1/2 contains all of the code that relates to SNC mode detection and checking that detection's reliability. - Patch 2/2 contains checking kernel support for SNC and modifying the messages at the end of affected tests. Changes v5: - Tests are skipped if snc_unreliable was set. - Moved resctrlfs.c changes from patch 2/2 to 1/2. - Removed CAT changes since it's not impacted by SNC in the selftest. - Updated various comments. - Fixed a bunch of minor issues pointed out in the review. Changes v4: - Printing SNC warnings at the start of every test. - Printing SNC warnings at the end of every relevant test. - Remove global snc_mode variable, consolidate snc detection functions into one. - Correct minor mistakes. Changes v3: - Reworked patch 2. - Changed minor things in patch 1 like function name and made corrections to the patch message. Changes v2: - Removed patches 2 and 3 since now this part will be supported by the kernel. Sub-Numa Clustering (SNC) allows splitting CPU cores, caches and memory into multiple NUMA nodes. When enabled, NUMA-aware applications can achieve better performance on bigger server platforms. SNC support in the kernel was merged into x86/cache [1]. With SNC enabled and kernel support in place all the tests will function normally (aside from effective cache size). There might be a problem when SNC is enabled but the system is still using an older kernel version without SNC support. Currently the only message displayed in that situation is a guess that SNC might be enabled and is causing issues. That message also is displayed whenever the test fails on an Intel platform. Add a mechanism to discover kernel support for SNC which will add more meaning and certainty to the error message. Add runtime SNC mode detection and verify how reliable that information is. Series was tested on Ice Lake server platforms with SNC disabled, SNC-2 and SNC-4. The tests were also ran with and without kernel support for SNC. Series applies cleanly on kselftest/next.

[PATCH net-next v5 0/6] tls: implement key updates for TLS1.3

by Sabrina Dubroca

This adds support for receiving KeyUpdate messages (RFC 8446, 4.6.3 [1]). A sender transmits a KeyUpdate message and then changes its TX key. The receiver should react by updating its RX key before processing the next message. This patchset implements key updates by: 1. pausing decryption when a KeyUpdate message is received, to avoid attempting to use the old key to decrypt a record encrypted with the new key 2. returning -EKEYEXPIRED to syscalls that cannot receive the KeyUpdate message, until the rekey has been performed by userspace 3. passing the KeyUpdate message to userspace as a control message 4. allowing updates of the crypto_info via the TLS_TX/TLS_RX setsockopts This API has been tested with gnutls to make sure that it allows userspace libraries to implement key updates [2]. Thanks to Frantisek Krenzelok <fkrenzel(a)redhat.com> for providing the implementation in gnutls and testing the kernel patches. ======================================================================= Discussions around v2 of this patchset focused on how HW offload would interact with rekey. RX - The existing SW path will handle all records between the KeyUpdate message signaling the change of key and the new key becoming known to the kernel -- those will be queued encrypted, and decrypted in SW as they are read by userspace (once the key is provided, ie same as this patchset) - Call ->tls_dev_del + ->tls_dev_add immediately during setsockopt(TLS_RX) TX - After setsockopt(TLS_TX), switch to the existing SW path (not the current device_fallback) until we're able to re-enable HW offload - tls_device_sendmsg will call into tls_sw_sendmsg under lock_sock to avoid changing socket ops during the rekey while another thread might be waiting on the lock - We only re-enable HW offload (call ->tls_dev_add to install the new key in HW) once all records sent with the old key have been ACKed. At this point, all unacked records are SW-encrypted with the new key, and the old key is unused by both HW and retransmissions. - If there are no unacked records when userspace does setsockopt(TLS_TX), we can (try to) install the new key in HW immediately. - If yet another key has been provided via setsockopt(TLS_TX), we don't install intermediate keys, only the latest. - TCP notifies ktls of ACKs via the icsk_clean_acked callback. In case of a rekey, tls_icsk_clean_acked will record when all data sent with the most recent past key has been sent. The next call to sendmsg will install the new key in HW. - We close and push the current SW record before reenabling offload. If ->tls_dev_add fails to install the new key in HW, we stay in SW mode. We can add a counter to keep track of this. In addition: Because we can't change socket ops during a rekey, we'll also have to modify do_tls_setsockopt_conf to check ctx->tx_conf and only call either tls_set_device_offload or tls_set_sw_offload. RX already uses the same ops for both TLS_HW and TLS_SW, so we could switch between HW and SW mode on rekey. An alternative would be to have a common sendmsg which locks the socket and then calls the correct implementation. We'll need that anyway for the offload under rekey case, so that would only add a test to the SW path's ops (compared to the current code). That should allow us to simplify build_protos a bit, but might have a performance impact - we'll need to check it if we want to go that route. ======================================================================= Changes since v4: - add counter for received KeyUpdate messages - improve wording in the documentation - improve handling of bogus messages when looking for KeyUpdate's - some coding style clean ups Changes since v3: - rebase on top of net-next - rework tls_check_pending_rekey according to Jakub's feedback - add statistics for rekey: {RX,TX}REKEY{OK,ERROR} - some coding style clean ups Link: https://lore.kernel.org/netdev/cover.1731597571.git.sd@queasysnail.net/ [v4] Link: https://lore.kernel.org/netdev/cover.1691584074.git.sd@queasysnail.net/ [v3] Link: https://lore.kernel.org/netdev/cover.1676052788.git.sd@queasysnail.net/ [v2] Link: https://lore.kernel.org/netdev/cover.1673952268.git.sd@queasysnail.net/ [v1] Link: https://www.rfc-editor.org/rfc/rfc8446#section-4.6.3 [1] Link: https://gitlab.com/gnutls/gnutls/-/merge_requests/1625 [2] Sabrina Dubroca (6): tls: block decryption when a rekey is pending tls: implement rekey for TLS1.3 tls: add counters for rekey docs: tls: document TLS1.3 key updates selftests: tls: add key_generation argument to tls_crypto_info_init selftests: tls: add rekey tests Documentation/networking/tls.rst | 36 +++ include/net/tls.h | 3 + include/uapi/linux/snmp.h | 5 + net/tls/tls.h | 3 +- net/tls/tls_device.c | 2 +- net/tls/tls_main.c | 71 ++++- net/tls/tls_proc.c | 5 + net/tls/tls_sw.c | 140 ++++++--- tools/testing/selftests/net/tls.c | 478 +++++++++++++++++++++++++++++- 9 files changed, 682 insertions(+), 61 deletions(-) -- 2.47.1

[PATCH net 3/5] selftests: net: support setting recv_size in YNL

by Jakub Kicinski

recv_size parameter allows constraining the buffer size for dumps. It's useful in testing kernel handling of dump continuation, IOW testing dumps which span multiple skbs. Let the tests set this parameter when initializing the YNL family. Keep the normal default, we don't want tests to unintentionally behave very differently than normal code.

[PATCH 0/4] KVM: selftests: dirty_log_test: fixes for running the test nested

by Maxim Levitsky

As a part of the effort to start running kvm selftests nested, this patch series contains several fixes to the dirty_log_test, which allows this test to run nested very well. I also included a mostly nop change to KVM, to reverse the order in which the PML log is read to align more closely to the hardware. It should not affect regular users of the dirty logging but it fixes a unit test specific assumption in the dirty_log_test dirty-ring mode. Patch 4 fixes a very rare problem, which is hard to reproduce with standard test parameters, but due to some weird timing issue, it actually happened a few times on my machine which prompted me to investigate it. The issue can be reproduced well by running the test nested (without patch 4 applied) with a very short iteration time and with a few iterations in a loop like this: while ./dirty_log_test -i 10 -I 1 -M dirty-ring ; do true ; done Or even better, it's possible to manually patch the test to not wait at all (effectively setting iteration time to 0), then it fails pretty fast. Best regards, Maxim Levitsky Maxim Levitsky (4): KVM: VMX: read the PML log in the same order as it was written KVM: selftests: dirty_log_test: Limit s390x workaround to s390x KVM: selftests: dirty_log_test: run the guest until some dirty ring entries were harvested KVM: selftests: dirty_log_test: support multiple write retires arch/x86/kvm/vmx/vmx.c | 32 +++++--- arch/x86/kvm/vmx/vmx.h | 1 + tools/testing/selftests/kvm/dirty_log_test.c | 79 +++++++++++++++++--- 3 files changed, 91 insertions(+), 21 deletions(-) -- 2.26.3

[PATCH v2 0/6] Enhance event delivery error handling

by Ivan Orlov

Currently, the situation when guest accesses MMIO during vectoring is handled differently on VMX and SVM: on VMX KVM returns internal error, when SVM goes into infinite loop trying to deliver an event again and again. This patch series eliminates this difference by returning a KVM internal error when guest performs MMIO during vectoring for both VMX and SVM. Also, introduce a selftest test case which covers the error handling mentioned above. V1 -> V2: - Make commit messages more brief, avoid using pronouns - Extract SVM error handling into a separate commit - Introduce a new X86EMUL_ return type and detect the unhandleable vectoring error in vendor-specific check_emulate_instruction instead of handling it in the common MMU code (which is specific for cached MMIO) Ivan Orlov (6): KVM: x86: Add function for vectoring error generation KVM: x86: Add emulation status for vectoring during MMIO KVM: VMX: Handle vectoring error in check_emulate_instruction KVM: SVM: Handle MMIO during vectroing error selftests: KVM: extract lidt into helper function selftests: KVM: Add test case for MMIO during vectoring arch/x86/include/asm/kvm_host.h | 12 ++++- arch/x86/kvm/kvm_emulate.h | 2 + arch/x86/kvm/svm/svm.c | 9 +++- arch/x86/kvm/vmx/vmx.c | 33 +++++------- arch/x86/kvm/x86.c | 27 ++++++++++ .../selftests/kvm/include/x86_64/processor.h | 7 +++ .../selftests/kvm/set_memory_region_test.c | 53 ++++++++++++++++++- .../selftests/kvm/x86_64/sev_smoke_test.c | 2 +- 8 files changed, 119 insertions(+), 26 deletions(-) -- 2.43.0

[PATCH v2 0/4] sched: Move task_mm_cid_work to mm delayed work

by Gabriele Monaco

This patchset moves the task_mm_cid_work to a preemptible and migratable context. This reduces the impact of this task to the scheduling latency of real time tasks. The change makes the recurrence of the task a bit more predictable. We also add optimisation and fixes to make sure the task_mm_cid_work works as intended. Patch 1 contains the main changes, removing the task_work on the scheduler tick and using a delayed_work instead. Patch 2 adds some optimisations to the approach, since we rely on a delayed_work, it is no longer required to check that the minimum interval passed since execution, we however terminate the call immediately if we see that no mm_cid is actually active, which could happen on processes sleeping for long time or which exited but whose mm has not been freed yet. Patch 3 allows the mm_cids to be actually compacted when a process reduces its number of threads, which was not the case since the same mm_cids were reused to improve cache locality, more details in [1]. Patch 4 adds a selftest to validate the functionality of the task_mm_cid_work (i.e. to compact the mm_cids), this test requires patch 3 to be applied. Changes since V1 [1]: * Re-arm the delayed_work at each invocation * Cancel the work synchronously at mmdrop * Remove next scan fields and completely rely on the delayed_work * Shrink mm_cid allocation with nr thread/affinity (Mathieu Desnoyers) * Add self test OVERHEAD COMPARISON In this section, I'm going to refer to head as the current state upstream without my patch applied, patch is the same head with these patches applied. Likewise, I'm going to refer to task_mm_cid_work as either the task or the function. The experiments are run on an aarch64 machine with 128 cores. The kernel has a bare configuration with PREEMPT_RT enabled. - Memory The patch introduces some memory overhead: * head uses a callback_head per thread (16 bytes) * patch relies on a delayed work per mm but drops a long (80 bytes net) Tasks with 5 threads or less have lower memory footprint with the current approach. Considering a task_struct can be 7-13 kB and an mm_struct is about 1.4 kB, the overhead should be acceptable. - Boot time I tested the patch booting a virtual machine with vng[2], both head and patch get similar boot times (around 8s). - Runtime I run some rather demanding tests to show what could possibly be a worst case in the approach introduced by this patch. The following tests are running again in vng to have a plain system, running mostly the stressors (if there). Unless differently specified, time is in us. All tests run for 30s. The stress-ng tests were run with 128 stressors, I will omit from the table for clarity. No load head patch running processes(threads): 12(12) 12(12) duration(avg,max,sum): 75,426,987 2,42,45ms invocations: 13 20k stress-ng --cpu-load 80 head patch running processes(threads): 129(129) 129(129) duration(avg,max,sum): 20,2ms,740ms 7,774,280ms invocations: 36k 39k stress-ng --fork head patch running processes(threads): 3.6k(3.6k) 4k(4k) duration(avg,max,sum): 34,41,720 19,457,880ms invocations: 21 46k stress-ng --pthread-max 4 head patch running processes(threads): 129(4k) 129(4k) duration(avg,max,sum): 31,195,41ms 21,1ms,830ms invocations: 1290 38k It is important to note that some of those stressors run for a very short period of time to just fork/create a thread, this heavily favours head since the task won't simply run as often. Moreover, the duration time needs to be read carefully, since the task can now be preempted by threads, I tried to exclude that from the computation, but to keep the probes simple, I didn't exclude interference caused by interrupts. On the same system while isolated, the task runs in about 30-35ms, it is hence highly likely that much larger values are only due to interruptions, rather than the function actually running that long. I will post another email with the scripts used to retrieve the data and more details about the runtime distribution.

[PATCH v2 00/13] iommufd: Add vIOMMU infrastructure (Part-3: vIRQ)

by Nicolin Chen

As the part-3 of the vIOMMU infrastructure, this series introduces a vIRQ object. The existing FAULT object provides a nice notification pathway to the user space already, so let vIRQ reuse the infrastructure. Mimicing the HWPT structure, add a common EVENTQ structure to support its derivatives: EVENTQ_IOPF (the prior FAULT object) and EVENTQ_VIRQ (new). IOMMUFD_CMD_VIRQ_ALLOC is introduced to allocate EVENTQ_VIRQ for vIOMMUs. One vIOMMU can have multiple vIRQs in different types but can not support multiple vIRQs with the same types. The forwarding part is fairly simple but might need to replace a physical device ID with a virtual device ID in a driver-level IRQ data structure. So, this comes with some helpers for drivers to use.

[PATCH v4 0/2] selftests/futex: Create test for robust list

by André Almeida

This patchset creates a selftest for the robust list interface, to track regressions and assure that the interface keeps working as expected. In this version I removed the kselftest_harness include, but I expanded the current futex selftest API a little bit with basic ASSERT_ macros to make the test easier to write and read. In the future, hopefully we can move all futex selftests to the kselftest_harness API anyway. This is the expected output: TAP version 13 1..6 ok 1 test_robustness ok 2 test_set_robust_list_invalid_size ok 3 test_get_robust_list_self ok 4 test_get_robust_list_child ok 5 test_set_list_op_pending ok 6 test_robust_list_multiple_elements # Totals: pass:6 fail:0 xfail:0 xpass:0 skip:0 error:0 Changelog v4: - Fixed clang warning "robust_list.c:121: converts between pointers to integer types with different sign" v3: https://lore.kernel.org/lkml/20241010011142.905297-1-andrealmeid@igalia.com/ - Create ASSERT_ macros for futex selftests - Dropped kselftest_harness include, using just futex test API André Almeida (2): selftests/futex: Add ASSERT_ macros selftests/futex: Create test for robust list .../selftests/futex/functional/.gitignore | 1 + .../selftests/futex/functional/Makefile | 3 +- .../selftests/futex/functional/robust_list.c | 513 ++++++++++++++++++ .../testing/selftests/futex/include/logging.h | 28 + 4 files changed, 544 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/futex/functional/robust_list.c -- 2.47.1

[PATCH net-next v5 0/5] net: Improve netns handling in RTNL and ip_tunnel

by Xiao Liang

This patch series includes some netns-related improvements and fixes for RTNL and ip_tunnel, to make link creation more intuitive: - Creating link in another net namespace doesn't conflict with link names in current one. - Refector rtnetlink link creation. Create link in target namespace directly. Pass both source and link netns to drivers via newlink() callback. So that # ip link add netns ns1 link-netns ns2 tun0 type gre ... will create tun0 in ns1, rather than create it in ns2 and move to ns1. And don't conflict with another interface named "tun0" in current netns. --- v5: - Fix function doc in batman-adv. - Include peer_net in rtnl newlink parameters. v4: link: https://lore.kernel.org/all/20241118143244.1773-1-shaw.leon@gmail.com/ - Pack newlink() parameters to a single struct. - Use ynl async_msg_queue.empty() in selftest. v3: link: https://lore.kernel.org/all/20241113125715.150201-1-shaw.leon@gmail.com/ - Drop "netns_atomic" flag and module parameter.

[PATCH v6 00/28] NT synchronization primitive driver

by Elizabeth Figura

This patch series implements a new char misc driver, /dev/ntsync, which is used to implement Windows NT synchronization primitives. NT synchronization primitives are unique in that the wait functions both are vectored, operate on multiple types of object with different behaviour (mutex, semaphore, event), and affect the state of the objects they wait on. This model is not compatible with existing kernel synchronization objects or interfaces, and therefore the ntsync driver implements its own wait queues and locking. This patch series is rebased against the "char-misc-next" branch of gregkh/char-misc.git. == Background == The Wine project emulates the Windows API in user space. One particular part of that API, namely the NT synchronization primitives, have historically been implemented via RPC to a dedicated "kernel" process. However, more recent applications use these APIs more strenuously, and the overhead of RPC has become a bottleneck. The NT synchronization APIs are too complex to implement on top of existing primitives without sacrificing correctness. Certain operations, such as NtPulseEvent() or the "wait-for-all" mode of NtWaitForMultipleObjects(), require direct control over the underlying wait queue, and implementing a wait queue sufficiently robust for Wine in user space is not possible. This proposed driver, therefore, implements the problematic interfaces directly in the Linux kernel. This driver was presented at Linux Plumbers Conference 2023. For those further interested in the history of synchronization in Wine and past attempts to solve this problem in user space, a recording of the presentation can be viewed here: https://www.youtube.com/watch?v=NjU4nyWyhU8 == Performance == The performance measurements described below are copied from earlier versions of the patch set. While some of the code has changed, I do not currently anticipate that it has changed drastically enough to affect those measurements. The gain in performance varies wildly depending on the application in question and the user's hardware. For some games NT synchronization is not a bottleneck and no change can be observed, but for others frame rate improvements of 50 to 150 percent are not atypical. The following table lists frame rate measurements from a variety of games on a variety of hardware, taken by users Dmitry Skvortsov, FuzzyQuils, OnMars, and myself: Game Upstream ntsync improvement =========================================================================== Anger Foot 69 99 43% Call of Juarez 99.8 224.1 125% Dirt 3 110.6 860.7 678% Forza Horizon 5 108 160 48% Lara Croft: Temple of Osiris 141 326 131% Metro 2033 164.4 199.2 21% Resident Evil 2 26 77 196% The Crew 26 51 96% Tiny Tina's Wonderlands 130 360 177% Total War Saga: Troy 109 146 34% =========================================================================== == Patches == The intended semantics of the patches are broadly intended to match those of the corresponding Windows functions. For those not already familiar with the Windows functions (or their undocumented behaviour), patch 27/28 provides a detailed specification, and individual patches also include a brief description of the API they are implementing. The patches making use of this driver in Wine can be retrieved or browsed here: https://repo.or.cz/wine/zf.git/shortlog/refs/heads/ntsync5 == Previous versions == No changes were made from v5 other than rebasing on top of the 6.13-rc1 char-misc-next tree. I would like to repeat a question from the last round of review, though. Two changes were suggested related to API design, which I did not make because the APIs in question were already released in upstream Linux. However, the driver is also completely nonfunctional and hidden behind BROKEN, so would this be acceptable anyway? The changes in question are: * rename NTSYNC_IOC_SEM_POST to NTSYNC_IOC_SEM_RELEASE (matching the NT terminology instead of POSIX), * change object creation ioctls to return the fds directly in the return value instead of through the args struct. I would also still appreciate a clarification on the advice in [1], which is why I didn't do this in the first place.

[PATCH 0/3] kselftest framework to introduce TEST_CONFIG_DEPS

by Siddharth Menon

Currently, kselftests does not have a generalised mechanism to skip compilation and run tests when required kernel configuration options are disabled. This patch series addresses this limitation by introducing a new flag, 'TEST_CONFIG_DEPS' in lib.mk, along with corresponding updates to the documentation. The selftests/livepatch/Makefile has been updated to utilize TEST_CONFIG_DEPS.

[PATCH 00/15] KVM: x86: Introduce new ioctl KVM_TRANSLATE2

by Nikolas Wipper

This series introduces a new ioctl KVM_TRANSLATE2, which expands on KVM_TRANSLATE. It is required to implement Hyper-V's HvTranslateVirtualAddress hyper-call as part of the ongoing effort to emulate HyperV's Virtual Secure Mode (VSM) within KVM and QEMU. The hyper- call requires several new KVM APIs, one of which is KVM_TRANSLATE2, which implements the core functionality of the hyper-call. The rest of the required functionality will be implemented in subsequent series. Other than translating guest virtual addresses, the ioctl allows the caller to control whether the access and dirty bits are set during the page walk. It also allows specifying an access mode instead of returning viable access modes, which enables setting the bits up to the level that caused a failure. Additionally, the ioctl provides more information about why the page walk failed, and which page table is responsible. This functionality is not available within KVM_TRANSLATE, and can't be added without breaking backwards compatiblity, thus a new ioctl is required. The ioctl was designed to facilitate as many other use cases as possible apart from VSM. The error codes were intentionally chosen to be broad enough to avoid exposing architecture specific details. Even though HvTranslateVirtualAddress only really needs one flag to set the accessed and dirty bits whenever possible, that was split into several flags so that future users can chose more gradually when these bits should be set. Furthermore, as much information as possible is provided to the caller. The patch series includes selftests for the ioctl, as well as fuzzy testing on random garbage guest page table entries. All previously passing KVM selftests and KVM unit tests still pass. Series overview: - 1: Document the new ioctl - 2-11: Update the page walker in preparation - 12-14: Implement the ioctl - 15: Implement testing This series, alongside the series by Nicolas Saenz Julienne [1] introducing the core building blocks for VSM and the accompanying QEMU implementation [2], is capable of booting Windows Server 2019.

[PATCH 0/4] drivers: base: Don't match device with NULL of_node/fwnode/etc + tests

by Brian Norris

This series: 1. makes the behavior of_find_device_by_node(), bus_find_device_by_of_node(), bus_find_device_by_fwnode(), etc., more consistent when provided with a NULL node/handle; 2. adds kunit tests to validate the new NULL-argument behavior; and 3. makes some related improvements and refactoring for the drivers/base/ kunit tests. This series aims to prevent problems like the ones resolved in commit 5c8418cf4025 ("PCI/pwrctrl: Unregister platform device only if one actually exists").

[PATCH AUTOSEL 6.12 21/36] bpf: Zero index arg error string for dynptr and iter

by Sasha Levin

From: Kumar Kartikeya Dwivedi <memxor(a)gmail.com> [ Upstream commit bd74e238ae6944b462f57ce8752440a011ba4530 ] Andrii spotted that process_dynptr_func's rejection of incorrect argument register type will print an error string where argument numbers are not zero-indexed, unlike elsewhere in the verifier. Fix this by subtracting 1 from regno. The same scenario exists for iterator messages. Fix selftest error strings that match on the exact argument number while we're at it to ensure clean bisection.

[PATCH] cgroup/cpuset: Prevent leakage of isolated CPUs into sched domains

by Waiman Long

Isolated CPUs are not allowed to be used in a non-isolated partition. The only exception is the top cpuset which is allowed to contain boot time isolated CPUs. Commit ccac8e8de99c ("cgroup/cpuset: Fix remote root partition creation problem") introduces a simplified scheme of including only partition roots in sched domain generation. However, it does not properly account for this exception case. This can result in leakage of isolated CPUs into a sched domain. Fix it by making sure that isolated CPUs are excluded from the top cpuset before generating sched domains. Also update the way the boot time isolated CPUs are handled in test_cpuset_prs.sh to make sure that those isolated CPUs are really isolated instead of just skipping them in the tests.

[PATCH v2 0/4] Migrate PCI Endpoint Subsystem tests to Kselftest

by Manivannan Sadhasivam

Hi, This series carries forward the effort to add Kselftest for PCI Endpoint Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version based on another patch that fixes the return values of IOCTLs in pci_endpoint_test driver and did many cleanups. Since the resulting work modified the initial version substantially, I took over the authorship. This series also incorporates the review comment by Shuah Khan [2] to move the existing tests from 'tools/pci' to 'tools/testing/kselftest/pci_endpoint' before migrating to Kselftest framework. I made sure that the tests are executable in each commit and updated documentation accordingly. NOTE: Patch 1 is strictly not related to this series, but necessary to execute Kselftests with Qualcomm Endpoint devices. So this can be merged separately. - Mani [1] https://lore.kernel.org/linux-pci/20221007053934.5188-1-aman1.gupta@samsung… [2] https://lore.kernel.org/linux-pci/b2a5db97-dc59-33ab-71cd-f591e0b1b34d@linu… Changes in v2: * Added a patch that fixes return values of IOCTL in pci_endpoint_test driver * Moved the existing tests to new location before migrating * Added a fix for BARs on Qcom devices * Updated documentation and also added fixture variants for memcpy & DMA modes Manivannan Sadhasivam (4): PCI: qcom-ep: Mark BAR0/BAR2 as 64bit BARs and BAR1/BAR3 as RESERVED misc: pci_endpoint_test: Fix the return value of IOCTL selftests: Move PCI Endpoint tests from tools/pci to Kselftests selftests: pci_endpoint: Migrate to Kselftest framework Documentation/PCI/endpoint/pci-test-howto.rst | 144 +++------- MAINTAINERS | 2 +- drivers/misc/pci_endpoint_test.c | 236 ++++++++--------- drivers/pci/controller/dwc/pcie-qcom-ep.c | 4 + tools/pci/Build | 1 - tools/pci/Makefile | 58 ---- tools/pci/pcitest.c | 250 ------------------ tools/pci/pcitest.sh | 72 ----- tools/testing/selftests/Makefile | 1 + .../testing/selftests/pci_endpoint/.gitignore | 2 + tools/testing/selftests/pci_endpoint/Makefile | 7 + tools/testing/selftests/pci_endpoint/config | 4 + .../pci_endpoint/pci_endpoint_test.c | 186 +++++++++++++ 13 files changed, 365 insertions(+), 602 deletions(-) delete mode 100644 tools/pci/Build delete mode 100644 tools/pci/Makefile delete mode 100644 tools/pci/pcitest.c delete mode 100644 tools/pci/pcitest.sh create mode 100644 tools/testing/selftests/pci_endpoint/.gitignore create mode 100644 tools/testing/selftests/pci_endpoint/Makefile create mode 100644 tools/testing/selftests/pci_endpoint/config create mode 100644 tools/testing/selftests/pci_endpoint/pci_endpoint_test.c -- 2.25.1

This adds support for receiving KeyUpdate messages (RFC 8446, 4.6.3 [1]). A sender transmits a KeyUpdate message and then changes its TX key. The receiver should react by updating its RX key before processing the next message. This patchset implements key updates by: 1. pausing decryption when a KeyUpdate message is received, to avoid attempting to use the old key to decrypt a record encrypted with the new key 2. returning -EKEYEXPIRED to syscalls that cannot receive the KeyUpdate message, until the rekey has been performed by userspace 3. passing the KeyUpdate message to userspace as a control message 4. allowing updates of the crypto_info via the TLS_TX/TLS_RX setsockopts This API has been tested with gnutls to make sure that it allows userspace libraries to implement key updates [2]. Thanks to Frantisek Krenzelok <fkrenzel(a)redhat.com> for providing the implementation in gnutls and testing the kernel patches. ======================================================================= Discussions around v2 of this patchset focused on how HW offload would interact with rekey. RX - The existing SW path will handle all records between the KeyUpdate message signaling the change of key and the new key becoming known to the kernel -- those will be queued encrypted, and decrypted in SW as they are read by userspace (once the key is provided, ie same as this patchset) - Call ->tls_dev_del + ->tls_dev_add immediately during setsockopt(TLS_RX) TX - After setsockopt(TLS_TX), switch to the existing SW path (not the current device_fallback) until we're able to re-enable HW offload - tls_device_sendmsg will call into tls_sw_sendmsg under lock_sock to avoid changing socket ops during the rekey while another thread might be waiting on the lock - We only re-enable HW offload (call ->tls_dev_add to install the new key in HW) once all records sent with the old key have been ACKed. At this point, all unacked records are SW-encrypted with the new key, and the old key is unused by both HW and retransmissions. - If there are no unacked records when userspace does setsockopt(TLS_TX), we can (try to) install the new key in HW immediately. - If yet another key has been provided via setsockopt(TLS_TX), we don't install intermediate keys, only the latest. - TCP notifies ktls of ACKs via the icsk_clean_acked callback. In case of a rekey, tls_icsk_clean_acked will record when all data sent with the most recent past key has been sent. The next call to sendmsg will install the new key in HW. - We close and push the current SW record before reenabling offload. If ->tls_dev_add fails to install the new key in HW, we stay in SW mode. We can add a counter to keep track of this. In addition: Because we can't change socket ops during a rekey, we'll also have to modify do_tls_setsockopt_conf to check ctx->tx_conf and only call either tls_set_device_offload or tls_set_sw_offload. RX already uses the same ops for both TLS_HW and TLS_SW, so we could switch between HW and SW mode on rekey. An alternative would be to have a common sendmsg which locks the socket and then calls the correct implementation. We'll need that anyway for the offload under rekey case, so that would only add a test to the SW path's ops (compared to the current code). That should allow us to simplify build_protos a bit, but might have a performance impact - we'll need to check it if we want to go that route. ======================================================================= Changes since v3: - rebase on top of net-next - rework tls_check_pending_rekey according to Jakub's feedback - add statistics for rekey: {RX,TX}REKEY{OK,ERROR} - some coding style clean ups Link: https://lore.kernel.org/netdev/cover.1691584074.git.sd@queasysnail.net/ [v3] Link: https://lore.kernel.org/netdev/cover.1676052788.git.sd@queasysnail.net/ [v2] Link: https://lore.kernel.org/netdev/cover.1673952268.git.sd@queasysnail.net/ [v1] Link: https://www.rfc-editor.org/rfc/rfc8446#section-4.6.3 [1] Link: https://gitlab.com/gnutls/gnutls/-/merge_requests/1625 [2] Sabrina Dubroca (6): tls: block decryption when a rekey is pending tls: implement rekey for TLS1.3 tls: add counters for rekey docs: tls: document TLS1.3 key updates selftests: tls: add key_generation argument to tls_crypto_info_init selftests: tls: add rekey tests Documentation/networking/tls.rst | 31 ++ include/net/tls.h | 3 + include/uapi/linux/snmp.h | 4 + net/tls/tls.h | 3 +- net/tls/tls_device.c | 2 +- net/tls/tls_main.c | 71 ++++- net/tls/tls_proc.c | 4 + net/tls/tls_sw.c | 138 +++++++-- tools/testing/selftests/net/tls.c | 480 +++++++++++++++++++++++++++++- 9 files changed, 676 insertions(+), 60 deletions(-) -- 2.47.0

[PATCH bpf 0/3] bpf, sockmap: Fix the element replace

by Michal Luczaj

Series takes care of two issues with sockmap update: inconsistent behaviour after update with same, and race/refcount imbalance on element replace. I am hesitant if patch 3/3 ("bpf, sockmap: Fix race between element replace and close()") is the right approach. I might have missed some detail of the current __sock_map_delete() implementation. I'd be grateful for comments, thanks.

[RFC PATCH v3 00/15] context_tracking,x86: Defer some IPIs until a user->kernel transition

by Valentin Schneider

Context ======= We've observed within Red Hat that isolated, NOHZ_FULL CPUs running a pure-userspace application get regularly interrupted by IPIs sent from housekeeping CPUs. Those IPIs are caused by activity on the housekeeping CPUs leading to various on_each_cpu() calls, e.g.: 64359.052209596 NetworkManager 0 1405 smp_call_function_many_cond (cpu=0, func=do_kernel_range_flush) smp_call_function_many_cond+0x1 smp_call_function+0x39 on_each_cpu+0x2a flush_tlb_kernel_range+0x7b __purge_vmap_area_lazy+0x70 _vm_unmap_aliases.part.42+0xdf change_page_attr_set_clr+0x16a set_memory_ro+0x26 bpf_int_jit_compile+0x2f9 bpf_prog_select_runtime+0xc6 bpf_prepare_filter+0x523 sk_attach_filter+0x13 sock_setsockopt+0x92c __sys_setsockopt+0x16a __x64_sys_setsockopt+0x20 do_syscall_64+0x87 entry_SYSCALL_64_after_hwframe+0x65 The heart of this series is the thought that while we cannot remove NOHZ_FULL CPUs from the list of CPUs targeted by these IPIs, they may not have to execute the callbacks immediately. Anything that only affects kernelspace can wait until the next user->kernel transition, providing it can be executed "early enough" in the entry code. The original implementation is from Peter [1]. Nicolas then added kernel TLB invalidation deferral to that [2], and I picked it up from there. Deferral approach ================= Storing each and every callback, like a secondary call_single_queue turned out to be a no-go: the whole point of deferral is to keep NOHZ_FULL CPUs in userspace for as long as possible - no signal of any form would be sent when deferring an IPI. This means that any form of queuing for deferred callbacks would end up as a convoluted memory leak. Deferred IPIs must thus be coalesced, which this series achieves by assigning IPIs a "type" and having a mapping of IPI type to callback, leveraged upon kernel entry. What about IPIs whose callback take a parameter, you may ask? Peter suggested during OSPM23 [3] that since on_each_cpu() targets housekeeping CPUs *and* isolated CPUs, isolated CPUs can access either global or housekeeping-CPU-local state to "reconstruct" the data that would have been sent via the IPI. This series does not affect any IPI callback that requires an argument, but the approach would remain the same (one coalescable callback executed on kernel entry). Kernel entry vs execution of the deferred operation =================================================== This is what I've referred to as the "Danger Zone" during my LPC24 talk [4]. There is a non-zero length of code that is executed upon kernel entry before the deferred operation can be itself executed (i.e. before we start getting into context_tracking.c proper), i.e.: idtentry_func_foo() <--- we're in the kernel irqentry_enter() enter_from_user_mode() __ct_user_exit() ct_kernel_enter_state() ct_work_flush() <--- deferred operation is executed here This means one must take extra care to what can happen in the early entry code, and that <bad things> cannot happen. For instance, we really don't want to hit instructions that have been modified by a remote text_poke() while we're on our way to execute a deferred sync_core(). Patches doing the actual deferral have more detail on this. Patches ======= o Patches 1-3 are standalone cleanups. o Patches 4-5 add an RCU testing feature. o Patches 6-8 add a new type of jump label for static keys that will not have their IPI be deferred. o Patch 9 adds objtool verification of static keys vs their text_poke IPI deferral o Patches 10-14 add the actual IPI deferrals o Patch 15 is a freebie to enable the deferral feature for NO_HZ_IDLE Patches are also available at: https://gitlab.com/vschneid/linux.git -b redhat/isolirq/defer/v3 RFC status ========== Things I'd like to get comments on and/or that are a bit WIPish; they're called out in the individual changelogs: o "forceful" jump label naming which I don't particularly like o objtool usage of 'offset_of(static_key.type)' and JUMP_TYPE_FORCEFUL. I've hardcoded them but it could do with being shoved in a kernel header objtool can include directly o The noinstr variant of __flush_tlb_all() doesn't have a paravirt variant, does it need one? Testing ======= Xeon E5-2699 system with SMToff, NOHZ_FULL, isolated CPUs. RHEL9 userspace. Workload is using rteval (kernel compilation + hackbench) on housekeeping CPUs and a dummy stay-in-userspace loop on the isolated CPUs. The main invocation is: $ trace-cmd record -e "csd_queue_cpu" -f "cpu & CPUS{$ISOL_CPUS}" \ -e "ipi_send_cpumask" -f "cpumask & CPUS{$ISOL_CPUS}" \ -e "ipi_send_cpu" -f "cpu & CPUS{$ISOL_CPUS}" \ rteval --onlyload --loads-cpulist=$HK_CPUS \ --hackbench-runlowmem=True --duration=$DURATION This only records IPIs sent to isolated CPUs, so any event there is interference (with a bit of fuzz at the start/end of the workload when spawning the processes). All tests were done with a duration of 1hr. v6.12-rc4 # This is the actual IPI count $ trace-cmd report trace-base.dat | grep callback | awk '{ print $(NF) }' | sort | uniq -c | sort -nr 1782 callback=generic_smp_call_function_single_interrupt+0x0 73 callback=0x0 # These are the different CSD's that caused IPIs $ trace-cmd report | grep csd_queue | awk '{ print $(NF-1) }' | sort | uniq -c | sort -nr 22048 func=tlb_remove_table_smp_sync 16536 func=do_sync_core 2262 func=do_flush_tlb_all 182 func=do_kernel_range_flush 144 func=rcu_exp_handler 60 func=sched_ttwu_pending v6.12-rc4 + patches: # This is the actual IPI count $ trace-cmd report | grep callback | awk '{ print $(NF) }' | sort | uniq -c | sort -nr 1168 callback=generic_smp_call_function_single_interrupt+0x0 74 callback=0x0 # These are the different CSD's that caused IPIs $ trace-cmd report | grep csd_queue | awk '{ print $(NF-1) }' | sort | uniq -c | sort -nr 23686 func=tlb_remove_table_smp_sync 192 func=rcu_exp_handler 65 func=sched_ttwu_pending Interestingly tlb_remove_table_smp_sync() started showing up on this machine, while it didn't during testing for v2 and it's the same machine.

[PATCH v2] selftests/vDSO: support DT_GNU_HASH

by Fangrui Song

glibc added support for DT_GNU_HASH in 2006 and DT_HASH has been obsoleted for more than one decade in many Linux distributions. Many vDSOs support DT_GNU_HASH. This patch adds selftests support.

[PATCH] selftests/bpf: Fix fill_link_info selftest on powerpc

by Saket Kumar Bhaskar

With CONFIG_KPROBES_ON_FTRACE enabled on powerpc, ftrace_location_range returns ftrace location for bpf_fentry_test1 at offset of 4 bytes from function entry. This is because branch to _mcount function is at offset of 4 bytes in function profile sequence. To fix this, add entry_offset of 4 bytes while verifying the address for kprobe entry address of bpf_fentry_test1 in verify_perf_link_info in selftest, when CONFIG_KPROBES_ON_FTRACE is enabled. Disassemble of bpf_fentry_test1: c000000000e4b080 <bpf_fentry_test1>: c000000000e4b080: a6 02 08 7c mflr r0 c000000000e4b084: b9 e2 22 4b bl c00000000007933c <_mcount> c000000000e4b088: 01 00 63 38 addi r3,r3,1 c000000000e4b08c: b4 07 63 7c extsw r3,r3 c000000000e4b090: 20 00 80 4e blr When CONFIG_PPC_FTRACE_OUT_OF_LINE [1] is enabled, these function profile sequence is moved out of line with an unconditional branch at offset 0. So, the test works without altering the offset for 'CONFIG_KPROBES_ON_FTRACE && CONFIG_PPC_FTRACE_OUT_OF_LINE' case. Disassemble of bpf_fentry_test1: c000000000f95190 <bpf_fentry_test1>: c000000000f95190: 00 00 00 60 nop c000000000f95194: 01 00 63 38 addi r3,r3,1 c000000000f95198: b4 07 63 7c extsw r3,r3 c000000000f9519c: 20 00 80 4e blr [1] https://lore.kernel.org/all/20241030070850.1361304-13-hbathini@linux.ibm.co… Fixes: 23cf7aa539dc ("selftests/bpf: Add selftest for fill_link_info") Signed-off-by: Saket Kumar Bhaskar <skb99(a)linux.ibm.com> --- .../selftests/bpf/prog_tests/fill_link_info.c | 4 ++++ .../selftests/bpf/progs/test_fill_link_info.c | 13 ++++++++++--- 2 files changed, 14 insertions(+), 3 deletions(-) diff --git a/tools/testing/selftests/bpf/prog_tests/fill_link_info.c b/tools/testing/selftests/bpf/prog_tests/fill_link_info.c index d50cbd804..e59af2aa6 100644 --- a/tools/testing/selftests/bpf/prog_tests/fill_link_info.c +++ b/tools/testing/selftests/bpf/prog_tests/fill_link_info.c @@ -171,6 +171,10 @@ static void test_kprobe_fill_link_info(struct test_fill_link_info *skel, /* See also arch_adjust_kprobe_addr(). */ if (skel->kconfig->CONFIG_X86_KERNEL_IBT) entry_offset = 4; + if (skel->kconfig->CONFIG_PPC64 && + skel->kconfig->CONFIG_KPROBES_ON_FTRACE && + !skel->kconfig->CONFIG_PPC_FTRACE_OUT_OF_LINE) + entry_offset = 4; err = verify_perf_link_info(link_fd, type, kprobe_addr, 0, entry_offset); ASSERT_OK(err, "verify_perf_link_info"); } else { diff --git a/tools/testing/selftests/bpf/progs/test_fill_link_info.c b/tools/testing/selftests/bpf/progs/test_fill_link_info.c index 6afa83475..fac33a14f 100644 --- a/tools/testing/selftests/bpf/progs/test_fill_link_info.c +++ b/tools/testing/selftests/bpf/progs/test_fill_link_info.c @@ -6,13 +6,20 @@ #include <stdbool.h> extern bool CONFIG_X86_KERNEL_IBT __kconfig __weak; +extern bool CONFIG_PPC_FTRACE_OUT_OF_LINE __kconfig __weak; +extern bool CONFIG_KPROBES_ON_FTRACE __kconfig __weak; +extern bool CONFIG_PPC64 __kconfig __weak; -/* This function is here to have CONFIG_X86_KERNEL_IBT - * used and added to object BTF. +/* This function is here to have CONFIG_X86_KERNEL_IBT, + * CONFIG_PPC_FTRACE_OUT_OF_LINE, CONFIG_KPROBES_ON_FTRACE, + * CONFIG_PPC6 used and added to object BTF. */ int unused(void) { - return CONFIG_X86_KERNEL_IBT ? 0 : 1; + return CONFIG_X86_KERNEL_IBT || + CONFIG_PPC_FTRACE_OUT_OF_LINE || + CONFIG_KPROBES_ON_FTRACE || + CONFIG_PPC64 ? 0 : 1; } SEC("kprobe") -- 2.45.2

[PATCH 0/4] selftest/mm: Remove warnings found by adding compiler flags

by Muhammad Usama Anjum

Recently, I reviewed a patch on the mm/kselftest mailing list about a test which had obvious type mismatch fix in it. It was strange why that wasn't caught during development and when patch was accepted. This led me to discover that those extra compiler options to catch these warnings aren't being used. When I added them, I found tens of warnings in just mm suite. In this series, I'm fixing those warnings in a few files. More fixes would be sent later.
