[PATCH bpf-next 0/5] bpf: make tracing program support multi-attach

by Menglong Dong

For now, the BPF program of type BPF_PROG_TYPE_TRACING is not allowed to be attached to multiple hooks, and we have to create a BPF program for each kernel function, for which we want to trace, even through all the program have the same (or similar) logic. This can consume extra memory, and make the program loading slow if we have plenty of kernel function to trace. In the commit 4a1e7c0c63e0 ("bpf: Support attaching freplace programs to multiple attach points"), the freplace BPF program is made to support attach to multiple attach points. And in this series, we extend it to fentry/fexit/raw_tp/... In the 1st patch, we add the support to record index of the accessed function args of the target for tracing program. Meanwhile, we add the function btf_check_func_part_match() to compare the accessed function args of two function prototype. This function will be used in the next commit. In the 2nd patch, we do some adjust to bpf_tracing_prog_attach() to make it support multiple attaching. In the 3rd patch, we allow to set bpf cookie in bpf_link_create() even if target_btf_id is set, as we are allowed to attach the tracing program to new target. In the 4th patch, we introduce the function libbpf_find_kernel_btf_id() to libbpf to find the btf type id of the kernel function, and this function will be used in the next commit. In the 5th patch, we add the testcases for this series. Menglong Dong (5): bpf: tracing: add support to record and check the accessed args bpf: tracing: support to attach program to multi hooks libbpf: allow to set coookie when target_btf_id is set in bpf_link_create libbpf: add the function libbpf_find_kernel_btf_id() selftests/bpf: add test cases for multiple attach of tracing program include/linux/bpf.h | 6 + include/uapi/linux/bpf.h | 1 + kernel/bpf/btf.c | 121 ++++++++++++++ kernel/bpf/syscall.c | 118 +++++++++++--- tools/lib/bpf/bpf.c | 17 +- tools/lib/bpf/libbpf.c | 83 ++++++++++ tools/lib/bpf/libbpf.h | 3 + tools/lib/bpf/libbpf.map | 1 + .../selftests/bpf/bpf_testmod/bpf_testmod.c | 49 ++++++ .../bpf/prog_tests/tracing_multi_attach.c | 153 ++++++++++++++++++ .../selftests/bpf/progs/tracing_multi_test.c | 66 ++++++++ 11 files changed, 583 insertions(+), 35 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/tracing_multi_attach.c create mode 100644 tools/testing/selftests/bpf/progs/tracing_multi_test.c -- 2.39.2

[PATCH 08/10] selftests/sched: Migrate cs_prctl_test to kselfttest

by Joel Fernandes (Google)

This test begs to be a kselftest, is in the kselftest hierarchy and does not even use a single kselftest API. Convert it. It simplifies some of the code and the output also looks much nicer now: Totals: pass:17 fail:0 xfail:0 xpass:0 skip:0 error:0 Signed-off-by: Joel Fernandes (Google) <joel(a)joelfernandes.org> --- tools/testing/selftests/sched/Makefile | 6 +- tools/testing/selftests/sched/cs_prctl_test.c | 74 ++++++++++--------- 2 files changed, 43 insertions(+), 37 deletions(-) diff --git a/tools/testing/selftests/sched/Makefile b/tools/testing/selftests/sched/Makefile index f491d741cb45..90c53bc1337e 100644 --- a/tools/testing/selftests/sched/Makefile +++ b/tools/testing/selftests/sched/Makefile @@ -1,9 +1,11 @@ # SPDX-License-Identifier: GPL-2.0+ TEST_GEN_PROGS := cs_dlserver_test - -cs_dlserver_test: cs_dlserver_test.c common.c +TEST_GEN_PROGS += cs_prctl_test CFLAGS += $(KHDR_INCLUDES) CFLAGS += -Wall include ../lib.mk + +$(OUTPUT)/cs_dlserver_test: cs_dlserver_test.c common.c +$(OUTPUT)/cs_prctl_test: cs_prctl_test.c common.c diff --git a/tools/testing/selftests/sched/cs_prctl_test.c b/tools/testing/selftests/sched/cs_prctl_test.c index 7ba057154343..bb7aee703cdf 100644 --- a/tools/testing/selftests/sched/cs_prctl_test.c +++ b/tools/testing/selftests/sched/cs_prctl_test.c @@ -28,10 +28,11 @@ #include <unistd.h> #include <time.h> #include <errno.h> -#include <stdio.h> #include <stdlib.h> #include <string.h> +#include "common.h" + #if __GLIBC_PREREQ(2, 30) == 0 #include <sys/syscall.h> static pid_t gettid(void) @@ -80,7 +81,7 @@ static int _prctl(int option, unsigned long arg2, unsigned long arg3, unsigned l int res;

[PATCH v3] selftests/mqueue: Set timeout to 180 seconds

by SeongJae Park

While mq_perf_tests runs with the default kselftest timeout limit, which is 45 seconds, the test takes about 60 seconds to complete on i3.metal AWS instances. Hence, the test always times out. Increase the timeout to 180 seconds.

[PATCH RESEND] selftests/ftrace: Add test to exercize function tracer across cpu hotplug

by Naveen N Rao

Add a test to exercize cpu hotplug with the function tracer active to ensure that sensitive functions in idle path are excluded from being traced.

[PATCH v4 0/3] selftests: add missing gitignore files and include generated objects

by Javier Carrasco

This series aims to keep the git status clean after building the selftests by adding some missing .gitignore files and object inclusion in existing .gitignore files. This is one of the requirements listed in the selftests documentation for new tests, but it is not always followed as desired. After adding these .gitignore files and including the generated objects, the working tree appears clean again.

Clearly there's a lot of incorrect format parameters that have never been checked. Instead adding Shuah and the KUnit people to the participants, and hoping that they will fix this up and we can get the format fixes for KUnit in the 6.9 timeframe. Side note: when I apply the above patch, the suggestions gcc spews out look invalid. Gcc seems to suggest turning a a format string of '%d" to "%ld" for a size_t variable. That's wrong. It should be "%zu". A 'size_t' can in fact be 'unsigned int' on some platforms (not just in theory), so %ld is really incorrect not just from a sign perspective. Anyway, I guess I will commit the immediate drm_buddy_test.c fix to get rid of the build issue, but the KUnit message format string issue will have to be a "let's get this fixed up _later_" issue.

Move bash helpers for outputting in KTAP format to the common selftests folder. This allows kselftests other than the dt one to source the file and make use of the helper functions.

[PATCH v3] bpf: Replace bpf_lpm_trie_key 0-length array with flexible array

by Kees Cook

Replace deprecated 0-length array in struct bpf_lpm_trie_key with flexible array. Found with GCC 13: ../kernel/bpf/lpm_trie.c:207:51: warning: array subscript i is outside array bounds of 'const __u8[0]' {aka 'const unsigned char[]'} [-Warray-bounds=] 207 | *(__be16 *)&key->data[i]); | ^~~~~~~~~~~~~ ../include/uapi/linux/swab.h:102:54: note: in definition of macro '__swab16' 102 | #define __swab16(x) (__u16)__builtin_bswap16((__u16)(x)) | ^ ../include/linux/byteorder/generic.h:97:21: note: in expansion of macro '__be16_to_cpu' 97 | #define be16_to_cpu __be16_to_cpu | ^~~~~~~~~~~~~ ../kernel/bpf/lpm_trie.c:206:28: note: in expansion of macro 'be16_to_cpu' 206 | u16 diff = be16_to_cpu(*(__be16 *)&node->data[i] ^ | ^~~~~~~~~~~ In file included from ../include/linux/bpf.h:7: ../include/uapi/linux/bpf.h:82:17: note: while referencing 'data' 82 | __u8 data[0]; /* Arbitrary size */ | ^~~~ And found at run-time under CONFIG_FORTIFY_SOURCE: UBSAN: array-index-out-of-bounds in kernel/bpf/lpm_trie.c:218:49 index 0 is out of range for type '__u8 [*]' Changing struct bpf_lpm_trie_key is difficult since has been used by userspace. For example, in Cilium: struct egress_gw_policy_key { struct bpf_lpm_trie_key lpm_key; __u32 saddr; __u32 daddr; }; While direct references to the "data" member haven't been found, there are static initializers what include the final member. For example, the "{}" here: struct egress_gw_policy_key in_key = { .lpm_key = { 32 + 24, {} }, .saddr = CLIENT_IP, .daddr = EXTERNAL_SVC_IP & 0Xffffff, }; To avoid the build time and run time warnings seen with a 0-sized trailing array for struct bpf_lpm_trie_key, introduce a new struct that correctly uses a flexible array for the trailing bytes, struct bpf_lpm_trie_key_u8. As part of this, include the "header" portion (which is just the "prefixlen" member), so it can be used by anything building a bpf_lpr_trie_key that has trailing members that aren't a u8 flexible array (like the self-test[1]), which is named struct bpf_lpm_trie_key_hdr. Adjust the kernel code to use struct bpf_lpm_trie_key_u8 through-out, and for the selftest to use struct bpf_lpm_trie_key_hdr. Add a comment to the UAPI header directing folks to the two new options.

[PATCH net 00/13] mptcp: misc. fixes for v6.8

by Matthieu Baerts (NGI0)

This series includes 4 types of fixes: Patches 1 and 2 force the path-managers not to allocate a new address entry when dealing with the "special" ID 0, reserved to the address of the initial subflow. These patches can be backported up to v5.19 and v5.12 respectively. Patch 3 to 6 fix the in-kernel path-manager not to create duplicated subflows. Patch 6 is the main fix, but patches 3 to 5 are some kind of pre-requisities: they fix some data races that could also lead to the creation of unexpected subflows. These patches can be backported up to v5.7, v5.10, v6.0, and v5.15 respectively. Note that patch 3 modifies the existing ULP API. No better solutions have been found for -net, and there is some similar prior art, see commit 0df48c26d841 ("tcp: add tcpi_bytes_acked to tcp_info"). Please also note that TLS ULP Diag has likely the same issue. Patches 7 to 9 fix issues in the selftests, when executing them on older kernels, e.g. when testing the last version of these kselftests on the v5.15.148 kernel as it is done by LKFT when validating stable kernels. These patches only avoid printing expected errors the console and marking some tests as "OK" while they have been skipped. Patches 7 and 8 can be backported up to v6.6. Patches 10 to 13 make sure all MPTCP selftests subtests have a unique name. It is important to have a unique (sub)test name in TAP, because that's the test identifier. Some CI environments might drop tests with duplicated names. Patches 10 to 12 can be backported up to v6.6.

[PATCH v13 00/21] KVM: xen: update shared_info and vcpu_info handling

by Paul Durrant

From: Paul Durrant <pdurrant(a)amazon.com> This series contains a new patch from Sean added since v12 [1]: * KVM: s390: Refactor kvm_is_error_gpa() into kvm_is_gpa_in_memslot() This frees up the function name kvm_is_error_gpa() such that it can then be re-defined in: * KVM: pfncache: allow a cache to be activated with a fixed (userspace) HVA to be used for a simple GPA validation helper function. The patch also now contains an either/or address check for GPA versus HVA in __kvm_gpc_refresh(). In: * KVM: pfncache: add a mark-dirty helper The function name has been changed from kvm_gpc_mark_dirty() to kvm_gpc_mark_dirty_in_slot(). In: * KVM: x86/xen: allow shared_info to be mapped by fixed HVA missing HVA validation checks have been added and the 'hva == 0' test has been changed to '!hva'. The KVM_XEN_ATTR_TYPE_SHARED_INFO and KVM_XEN_ATTR_TYPE_SHARED_INFO_HVA cases are still largely handled as one though as separation leads to duplicate calls to kvm_xen_shared_info_init() which looks messy. Also, patches with a 'xen' prefix have now been modified to have a 'x86/xen' prefix and patches with a 'selftests / xen' prefix have been modified to have simply a 'selftests' prefix.

[PATCH v2 0/2] KVM: s390: Fix AR parameter in MEM_OP ioctl

by Eric Farman

Hi Christian, Janosch, Heiko, Here is a new version for the AR/MEM_OP issue I'm attempting to address, with Heiko's feedback to v1. Patch 1 performs the host/guest access register swap that Christian suggested (instead of a full sync_reg/store_reg process). Patch 2 provides a selftest patch that exercises this scenario. Applying patch 2 without patch 1 fails in the following way: [eric@host linux]# ./tools/testing/selftests/kvm/s390x/memop TAP version 13 1..16 ok 1 simple copy ok 2 generic error checks ok 3 copy with storage keys ok 4 cmpxchg with storage keys ok 5 concurrently cmpxchg with storage keys ok 6 copy with key storage protection override ok 7 copy with key fetch protection ok 8 copy with key fetch protection override ==== Test Assertion Failure ==== s390x/memop.c:186: !r pid=5720 tid=5720 errno=4 - Interrupted system call 1 0x00000000010042af: memop_ioctl at memop.c:186 (discriminator 3) 2 0x0000000001006697: test_copy_access_register at memop.c:400 (discriminator 2) 3 0x0000000001002aaf: main at memop.c:1181 4 0x000003ffaec33a5b: ?? ??:0 5 0x000003ffaec33b5d: ?? ??:0 6 0x0000000001002ba9: _start at ??:?

[PATCH 0/3] selftests/resctrl: Simplify test cleanup functions

by Maciej Wieczor-Retman

Cleaning up after tests is implemented separately for individual tests and called at the end of each test execution. Since these functions are very similar and a more generalized test framework was introduced a function pointer in the resctrl_test struct can be used to reduce the amount of function calls. These functions are also all called in the ctrl-c handler because the handler isn't aware which test is currently running. Since the handler is implemented with a sigaction no function parameters can be passed there but information about what test is currently running can be passed with a global variable.

[PATCH v3 0/3] pstore: add multi-backend support

by Yuanhe Shu

I have been steadily working but struggled to find a seamlessly integrated way to implement tty frontend until Guilherme inspired me that multi-backend and tty frontend are actually two separate entities. This submission presents the 3rd iteration of my efforts, listing notable changes form the v1: 1. pstore.backend no longer acts as "registered backend", but "backends eligible for registration". 2. drop subdir since it will break user space 3. drop tty frontend since I haven't yet devised a satisfactory implementation strategy Changes from v2: 1. Fix ftrace.c build error as I did not compile with CONFIG_PSTORE_FTRACE. A heartfelt thank you to Kees and Guilherme for your suggestions. I firmly believe that a tty frontend is crucial for kdump debugging, and I am still dedicating effort to develop one. Hope in the future I can accomplish it with deeper comprehension with tty driver :) Yuanhe Shu (3): pstore: add multi-backend support Documentation: adjust pstore backend related document tools/testing: adjust pstore backend related selftest Documentation/ABI/testing/pstore | 8 +- .../admin-guide/kernel-parameters.txt | 4 +- fs/pstore/ftrace.c | 31 ++- fs/pstore/inode.c | 19 +- fs/pstore/internal.h | 4 +- fs/pstore/platform.c | 225 ++++++++++++------ fs/pstore/pmsg.c | 24 +- include/linux/pstore.h | 29 +++ tools/testing/selftests/pstore/common_tests | 8 +- .../selftests/pstore/pstore_post_reboot_tests | 65 ++--- tools/testing/selftests/pstore/pstore_tests | 2 +- 11 files changed, 295 insertions(+), 124 deletions(-) -- 2.39.3

[RFC PATCH v2 0/3] KVM: allow mapping of compound tail pages for IO or PFNMAP mapping

by Yan Zhao

This is a v2 for previous series [1] to allow mapping for compound tail pages for IO or PFNMAP mapping. Compared to v1, this version provides selftest to check functionality in KVM to map memslots for MMIO BARs (VMAs with flag VM_IO | VM_PFNMAP), as requested by Sean in [1]. The selftest can also be used to test series "allow mapping non-refcounted pages" [2]. Tag RFC is added because a test driver is introduced in patch 2, which is new to KVM selftest, and test "set_memory_region_io" in patch 3 depends on that the test driver is compiled and loaded in kernel. Besides, patch 3 calls vm_set_user_memory_region() directly without modifying vm_mem_add(). So, this series is sent to ensure the main direction is right. Thanks Yan [1] https://lore.kernel.org/all/20230719083332.4584-1-yan.y.zhao@intel.com/ [2] https://lore.kernel.org/all/20230911021637.1941096-1-stevensd@google.com/ v2: added patch 2 and 3 to do selftest for patch 1 (Sean).

[PATCH] selftests: fuxex: Report a unique test name per run of futex_requeue_pi

by Mark Brown

The futex_requeue_pi test program is run a number of times with different options to provide multiple test cases. Currently every time it runs it reports the result with a consistent string, meaning that automated systems parsing the TAP output from a test run have difficulty in distinguishing which test is which. The parameters used for the test are already logged as part of the test output, let's use the same format to roll them into the test name that we use with KTAP so that automated systems can follow the results of the individual cases that get run.

[PATCH v2] bpf: Replace bpf_lpm_trie_key 0-length array with flexible array

by Kees Cook

Replace deprecated 0-length array in struct bpf_lpm_trie_key with flexible array. Found with GCC 13: ../kernel/bpf/lpm_trie.c:207:51: warning: array subscript i is outside array bounds of 'const __u8[0]' {aka 'const unsigned char[]'} [-Warray-bounds=] 207 | *(__be16 *)&key->data[i]); | ^~~~~~~~~~~~~ ../include/uapi/linux/swab.h:102:54: note: in definition of macro '__swab16' 102 | #define __swab16(x) (__u16)__builtin_bswap16((__u16)(x)) | ^ ../include/linux/byteorder/generic.h:97:21: note: in expansion of macro '__be16_to_cpu' 97 | #define be16_to_cpu __be16_to_cpu | ^~~~~~~~~~~~~ ../kernel/bpf/lpm_trie.c:206:28: note: in expansion of macro 'be16_to_cpu' 206 | u16 diff = be16_to_cpu(*(__be16 *)&node->data[i] ^ | ^~~~~~~~~~~ In file included from ../include/linux/bpf.h:7: ../include/uapi/linux/bpf.h:82:17: note: while referencing 'data' 82 | __u8 data[0]; /* Arbitrary size */ | ^~~~ And found at run-time under CONFIG_FORTIFY_SOURCE: UBSAN: array-index-out-of-bounds in kernel/bpf/lpm_trie.c:218:49 index 0 is out of range for type '__u8 [*]' This includes fixing the selftest which was incorrectly using a variable length struct as a header, identified earlier[1]. Avoid this by just explicitly including the prefixlen member instead of struct bpf_lpm_trie_key. Note that it is not possible to simply remove the "data" member, as it is referenced by userspace cilium: struct egress_gw_policy_key in_key = { .lpm_key = { 32 + 24, {} }, .saddr = CLIENT_IP, .daddr = EXTERNAL_SVC_IP & 0Xffffff, }; systemd: ipv6_map_fd = bpf_map_new( BPF_MAP_TYPE_LPM_TRIE, offsetof(struct bpf_lpm_trie_key, data) + sizeof(uint32_t)*4, sizeof(uint64_t), ... The only risk to UAPI would be if sizeof() were used directly on the data member, which it does not seem to be. It is only used as a static initializer destination and to find its location via offsetof().

[PATCH 00/31] NT synchronization primitive driver

by Elizabeth Figura

This patch series introduces a new char misc driver, /dev/ntsync, which is used to implement Windows NT synchronization primitives. This was previously submitted as an RFC [1]. Since there were no major changes requested to the last RFC revision, I've stripped the RFC prefix. [1] https://lore.kernel.org/lkml/20240131021356.10322-1-zfigura@codeweavers.com/ == 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 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 31/31 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 == Implementation == Some aspects of the implementation may deserve particular comment: * In the interest of performance, each object is governed only by a single spinlock. However, NTSYNC_IOC_WAIT_ALL requires that the state of multiple objects be changed as a single atomic operation. In order to achieve this, we first take a device-wide lock ("wait_all_lock") any time we are going to lock more than one object at a time. The maximum number of objects that can be used in a vectored wait, and therefore the maximum that can be locked simultaneously, is 64. This number is NT's own limit. The acquisition of multiple spinlocks will degrade performance. This is a conscious choice, however. Wait-for-all is known to be a very rare operation in practice, especially with counts that approach the maximum, and it is the intent of the ntsync driver to optimize wait-for-any at the expense of wait-for-all as much as possible. * NT mutexes are tied to their threads on an OS level, and the kernel includes builtin support for "robust" mutexes. In order to keep the ntsync driver self-contained and avoid touching more code than necessary, it does not hook into task exit nor use pids. Instead, the user space emulator is expected to manage thread IDs and pass them as an argument to any relevant functions; this is the "owner" field of ntsync_wait_args and ntsync_mutex_args. When the emulator detects that a thread dies, it should therefore call NTSYNC_IOC_MUTEX_KILL on any open mutexes. * ntsync is module-capable mostly because there was nothing preventing it, and because it aided development. It is not a hard requirement, though. == Previous versions == Changes from the last (v2) RFC: * Add a new wait flag NTSYNC_WAIT_REALTIME. I had originally missed a corner case in NtWaitForMultipleObjects() related to its interaction with system time adjustments. Essentially the function is sometimes supposed to respect system time adjustments and sometimes supposed to ignore them, so in order to achieve this I've added a function that controls which flag is being synchronized to. Thanks Piotr Caban for catching this. * Add tests for overflowing semaphore and mutex counters, and a test for exceeding NTSYNC_MAX_WAIT_COUNT, per Andi Kleen. * Add a more intense and realistic test involving multiple threads using the same mutex to access data, per Andi Kleen. * Use check_add_overflow() instead of writing out overflow checking manually [and thereby avoid relying on -fwrapv]. * Add some missing headers that were being implicitly included: atomic.h, hrtimer.h, ktime.h, sched.h, sched/signal.h, spinlock.h. * Link to RFC v2: https://lore.kernel.org/lkml/20240131021356.10322-1-zfigura@codeweavers.com/ * Link to RFC v1: https://lore.kernel.org/lkml/20240124004028.16826-1-zfigura@codeweavers.com/ Elizabeth Figura (31): ntsync: Introduce the ntsync driver and character device. ntsync: Introduce NTSYNC_IOC_CREATE_SEM. ntsync: Introduce NTSYNC_IOC_SEM_POST. ntsync: Introduce NTSYNC_IOC_WAIT_ANY. ntsync: Introduce NTSYNC_IOC_WAIT_ALL. ntsync: Introduce NTSYNC_IOC_CREATE_MUTEX. ntsync: Introduce NTSYNC_IOC_MUTEX_UNLOCK. ntsync: Introduce NTSYNC_IOC_MUTEX_KILL. ntsync: Introduce NTSYNC_IOC_CREATE_EVENT. ntsync: Introduce NTSYNC_IOC_EVENT_SET. ntsync: Introduce NTSYNC_IOC_EVENT_RESET. ntsync: Introduce NTSYNC_IOC_EVENT_PULSE. ntsync: Introduce NTSYNC_IOC_SEM_READ. ntsync: Introduce NTSYNC_IOC_MUTEX_READ. ntsync: Introduce NTSYNC_IOC_EVENT_READ. ntsync: Introduce alertable waits. ntsync: Allow waits to use the REALTIME clock. selftests: ntsync: Add some tests for semaphore state. selftests: ntsync: Add some tests for mutex state. selftests: ntsync: Add some tests for NTSYNC_IOC_WAIT_ANY. selftests: ntsync: Add some tests for NTSYNC_IOC_WAIT_ALL. selftests: ntsync: Add some tests for wakeup signaling with WINESYNC_IOC_WAIT_ANY. selftests: ntsync: Add some tests for wakeup signaling with WINESYNC_IOC_WAIT_ALL. selftests: ntsync: Add some tests for manual-reset event state. selftests: ntsync: Add some tests for auto-reset event state. selftests: ntsync: Add some tests for wakeup signaling with events. selftests: ntsync: Add tests for alertable waits. selftests: ntsync: Add some tests for wakeup signaling via alerts. selftests: ntsync: Add a stress test for contended waits. maintainers: Add an entry for ntsync. docs: ntsync: Add documentation for the ntsync uAPI.

[PATCH resend] selftests: timers: clocksource-switch: Adapt progress to kselftest framework

by Geert Uytterhoeven

When adapting the test to the kselftest framework, a few printf() calls indicating test progress were not updated. Fix this by replacing these printf() calls by ksft_print_msg() calls. Fixes: ce7d101750ff8450 ("selftests: timers: clocksource-switch: adapt to kselftest framework") Signed-off-by: Geert Uytterhoeven <geert+renesas(a)glider.be> --- When just running the test, the output looks like: # Validating clocksource arch_sys_counter TAP version 13 1..12 ok 1 CLOCK_REALTIME ... # Validating clocksource ffca0000.timer TAP version 13 1..12 ok 1 CLOCK_REALTIME ... When redirecting the test output to a file, the progress prints are not interspersed with the test output, but collated at the end: TAP version 13 1..12 ok 1 CLOCK_REALTIME ... TAP version 13 1..12 ok 1 CLOCK_REALTIME ... # Totals: pass:6 fail:0 xfail:0 xpass:0 skip:6 error:0 # Validating clocksource arch_sys_counter # Validating clocksource ffca0000.timer ... This makes it hard to match the test results with the timer under test. Is there a way to fix this? The test does use fork().

[PATCH net-next 0/4] selftests: kselftest_harness: support using xfail

by Jakub Kicinski

Hi! When running selftests for our subsystem in our CI we'd like all tests to pass. Currently some tests use SKIP for cases they expect to fail, because the kselftest_harness limits the return codes to pass/fail/skip. Clean up and support the use of the full range of ksft exit codes under kselftest_harness. To avoid conflicts and get the functionality into the networking tree ASAP I'd like to put the patches on shared branch so that both linux-kselftest and net-next can pull it in. Shuah, please LMK if that'd work for you, and if so which -rc should I base the branch on. Or is merging directly into net-next okay? Jakub Kicinski (4): selftests: kselftest_harness: pass step via shared memory selftests: kselftest_harness: use KSFT_* exit codes selftests: kselftest_harness: support using xfail selftests: ip_local_port_range: use XFAIL instead of SKIP tools/testing/selftests/kselftest_harness.h | 67 ++++++++++++++----- .../selftests/net/ip_local_port_range.c | 2 +- 2 files changed, 52 insertions(+), 17 deletions(-) -- 2.43.0

[RFC 0/7] selftests: kselftest_harness: use common result printing helper

by Jakub Kicinski

Add a common result printing helper and always include test name in the result line. Previously when SKIP or XPASS would happen we printed: ok 1 # SKIP unknown without the test name. Now we'll print: ok 1 global.no_pad # SKIP unknown This appears to be more inline with: https://docs.kernel.org/dev-tools/ktap.html and makes parsing results easier. First 3 patches rearrange kselftest_harness to use exit code as an enum rather than separate passed/skip/xfail members. Rest of the series builds a ksft_test_result_code() helper. This series is on top of: https://lore.kernel.org/all/20240216002619.1999225-1-kuba@kernel.org/ Jakub Kicinski (7): selftests: kselftest_harness: generate test name once selftests: kselftest_harness: save full exit code in metadata selftests: kselftest_harness: use exit code to store skip and xfail selftests: kselftest: add ksft_test_result_code(), handling all exit codes selftests: kselftest_harness: print test name for SKIP and XFAIL selftests: kselftest_harness: let ksft_test_result_code() handle line termination selftests: kselftest_harness: let PASS / FAIL provide diagnostic tools/testing/selftests/kselftest.h | 45 ++++++++++ tools/testing/selftests/kselftest_harness.h | 96 ++++++++++----------- tools/testing/selftests/net/tls.c | 2 +- 3 files changed, 91 insertions(+), 52 deletions(-) -- 2.43.0

[PATCH net-next v2 0/4] selftests: kselftest_harness: support using xfail

by Jakub Kicinski

Hi! When running selftests for our subsystem in our CI we'd like all tests to pass. Currently some tests use SKIP for cases they expect to fail, because the kselftest_harness limits the return codes to pass/fail/skip. Clean up and support the use of the full range of ksft exit codes under kselftest_harness. Merge plan is to put it on top of -rc4 and merge into net-next. That way others should be able to pull the patches without any networking changes. v2: - fix alignment v1: https://lore.kernel.org/all/20240213154416.422739-1-kuba@kernel.org/ Jakub Kicinski (4): selftests: kselftest_harness: pass step via shared memory selftests: kselftest_harness: use KSFT_* exit codes selftests: kselftest_harness: support using xfail selftests: ip_local_port_range: use XFAIL instead of SKIP tools/testing/selftests/kselftest_harness.h | 67 ++++++++++++++----- .../selftests/net/ip_local_port_range.c | 2 +- 2 files changed, 52 insertions(+), 17 deletions(-) -- 2.43.0
