[PATCH 0/2] selftests: harness: refactor __constructor_order

by Masahiro Yamada

This series refactors __constructor_order because __constructor_order_last() is unneeded. BTW, the comments in kselftest_harness.h was confusing to me. As far as I tested, all arches executed constructors in the forward order. [test code] #include <stdio.h> static int x; static void __attribute__((constructor)) increment(void) { x += 1; } static void __attribute__((constructor)) multiply(void) { x *= 2; } int main(void) { printf("foo = %d\n", x); return 0; } It should print 2 for forward order systems, 1 for reverse order systems. I executed it on some archtes by using QEMU. I always got 2.

[PATCH net v3] selftests: net: local_termination: annotate the expected failures

by Jakub Kicinski

Vladimir said when adding this test: The bridge driver fares particularly badly [...] mainly because it does not implement IFF_UNICAST_FLT. See commit 90b9566aa5cd ("selftests: forwarding: add a test for local_termination.sh"). We don't want to hide the known gaps, but having a test which always fails prevents us from catching regressions. Report the cases we know may fail as XFAIL.

[PATCH] kunit: tool: Build compile_commands.json

by Brendan Jackman

compile_commands.json is used by clangd[1] to provide code navigation and completion functionality to editors. See [2] for an example configuration that includes this functionality for VSCode. It can currently be built manually when using kunit.py, by running: ./scripts/clang-tools/gen_compile_commands.py -d .kunit With this change however, it's built automatically so you don't need to manually keep it up to date. Unlike the manual approach, having make build the compile_commands.json means that it appears in the build output tree instead of at the root of the source tree, so you'll need to add --compile-commands-dir=.kunit to your clangd args for it to be found. This might turn out to be pretty annoying, I'm not sure yet. If so maybe we can later add some hackery to kunit.py to work around it.

[PATCH v4 00/66] Define _GNU_SOURCE for sources using

by Edward Liaw

Centralizes the definition of _GNU_SOURCE into KHDR_INCLUDES and removes redefinitions of _GNU_SOURCE from source code. 809216233555 ("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler. v1: https://lore.kernel.org/linux-kselftest/20240430235057.1351993-1-edliaw@goo… v2: https://lore.kernel.org/linux-kselftest/20240507214254.2787305-1-edliaw@goo… - Add -D_GNU_SOURCE to KHDR_INCLUDES so that it is in a single location. - Remove #define _GNU_SOURCE from source code to resolve redefinition warnings. v3: https://lore.kernel.org/linux-kselftest/20240509200022.253089-1-edliaw@goog… - Rebase onto linux-next 20240508. - Split patches by directory. - Add -D_GNU_SOURCE directly to CFLAGS in lib.mk. - Delete additional _GNU_SOURCE definitions from source code in linux-next. - Delete additional -D_GNU_SOURCE flags from Makefiles. v4: - Rebase onto linux-next 20240509. - Remove Fixes tag from patches that drop _GNU_SOURCE definition. - Restore space between comment and includes for selftests/damon.

[PATCH] selftest: rtc: Add to check rtc alarm status for alarm related test

by Joseph Jang

In alarm_wkalm_set and alarm_wkalm_set_minute test, they use different ioctl (RTC_ALM_SET/RTC_WKALM_SET) for alarm feature detection. They will skip testing if RTC_ALM_SET/RTC_WKALM_SET ioctl returns an EINVAL error code. This design may miss detecting real problems when the efi.set_wakeup_time() return errors and then RTC_ALM_SET/RTC_WKALM_SET ioctl returns an EINVAL error code with RTC_FEATURE_ALARM enabled. In order to make rtctest more explicit and robust, we propose to use RTC_PARAM_GET ioctl interface to check rtc alarm feature state before running alarm related tests. If the kernel does not support RTC_PARAM_GET ioctl interface, we will fallback to check the presence of "alarm" in /proc/driver/rtc. The rtctest requires the read permission on /dev/rtc0. The rtctest will be skipped if the /dev/rtc0 is not readable.

-D_GNU_SOURCE kselftest breakage in mainline

by Mark Brown

Hi, I'm seeing quite a lot of breakage in mainline as a result of daef47b89efd0b7 ("selftests: Compile kselftest headers with -D_GNU_SOURCE") and daef47b89efd0 ("selftests: Compile kselftest headers with -D_GNU_SOURCE") - thus far I've found that the use of static_assert() is triggering build breaks where testsuites aren't picking up the addition of _GNU_SOURCE (including stopping installing the other tests in the same directory), and there's a bunch of tests which #define _GNU_SOURCE in their code and now trigger build warnings. I'm looking at fixes and mitigations now. The build failures are taking out the ALSA tests entirely which has caused my personal CI to explode badly :/ Thanks, Mark

[PATCH] kselftest: Desecalate reporting of missing _GNU_SOURCE

by Mark Brown

Commit daef47b89efd0b7 ("selftests: Compile kselftest headers with -D_GNU_SOURCE") adds a static_assert() which means that things which would be warnings about undeclared functions get escalated into build failures. While we do actually want _GNU_SOURCE to be defined for users of kselftest_harness we haven't actually done that yet and this is causing widespread build breaks which were previously warnings about uses of asprintf() without prototypes, including causing other test programs in the same directory to fail to build. Since the build failures that are introduced cause additional issues due to make stopping builds early replace the static_assert() with a missing without making the error more severe than it already was. This will be moot once the issue is fixed properly but reduces the disruption while that happens.

[PATCH v6 00/17] riscv: Support vendor extensions and xtheadvector

by Charlie Jenkins

This patch series ended up much larger than expected, please bear with me! The goal here is to support vendor extensions, starting at probing the device tree and ending with reporting to userspace. The main design objective was to allow vendors to operate independently of each other. This has been achieved by delegating vendor extensions to a their own files and then accumulating the extensions in arch/riscv/kernel/vendor_extensions.c. Each vendor will have their own list of extensions they support. There is a new hwprobe key RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0 that is used to request which thead vendor extensions are supported on the current platform. This allows future vendors to allocate hwprobe keys for their vendor. On to the xtheadvector specific code. xtheadvector is a custom extension that is based upon riscv vector version 0.7.1 [1]. All of the vector routines have been modified to support this alternative vector version based upon whether xtheadvector was determined to be supported at boot. I have tested this with an Allwinner Nezha board. I ran into issues booting the board on 6.9-rc1 so I applied these patches to 6.8. There are a couple of minor merge conflicts that do arrise when doing that, so please let me know if you have been able to boot this board with a 6.9 kernel. I used SkiffOS [2] to manage building the image, but upgraded the U-Boot version to Samuel Holland's more up-to-date version [3] and changed out the device tree used by U-Boot with the device trees that are present in upstream linux and this series. Thank you Samuel for all of the work you did to make this task possible. To test the integration, I used the riscv vector kselftests. I modified the test cases to be able to more easily extend them, and then added a xtheadvector target that works by calling hwprobe and swapping out the vector asm if needed.

[PATCH v4] kunit: Cover 'assert.c' with tests

by Ivan Orlov

There are multiple assertion formatting functions in the `assert.c` file, which are not covered with tests yet. Implement the KUnit test for these functions. The test consists of 11 test cases for the following functions: 1) 'is_literal' 2) 'is_str_literal' 3) 'kunit_assert_prologue', test case for multiple assert types 4) 'kunit_assert_print_msg' 5) 'kunit_unary_assert_format' 6) 'kunit_ptr_not_err_assert_format' 7) 'kunit_binary_assert_format' 8) 'kunit_binary_ptr_assert_format' 9) 'kunit_binary_str_assert_format' 10) 'kunit_assert_hexdump' 11) 'kunit_mem_assert_format' The test aims at maximizing the branch coverage for the assertion formatting functions. As you can see, it covers some of the static helper functions as well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT' and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the corresponding definitions to `assert.h`. Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to how it is done for the string stream test. Signed-off-by: Ivan Orlov <ivan.orlov0322(a)gmail.com> --- V1 -> V2: - Check the output from the string stream for containing the key parts instead of comparing the results with expected strings char by char, as it was suggested by Rae Moar <rmoar(a)google.com>. Define two macros to make it possible (ASSERT_TEST_EXPECT_CONTAIN and ASSERT_TEST_EXPECT_NCONTAIN). - Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export them conditionally if kunit is enabled instead of including the `assert_test.c` file in the end of `assert.c`. This way we will decouple the test from the implementation (SUT). - Update the kunit_assert_hexdump test: now it checks for presense of the brackets '<>' around the non-matching bytes, instead of comparing the kunit_assert_hexdump output char by char. V2 -> V3: - Make test case array and test suite definitions static - Change the condition in `assert.h`: we should declare VISIBLE_IF_KUNIT functions in the header file when CONFIG_KUNIT is enabled, not CONFIG_KUNIT_TEST. Otherwise, if CONFIG_KUNIT_TEST is disabled, VISIBLE_IF_KUNIT functions in the `assert.c` are not static, and prototypes for them can't be found. - Add MODULE_LICENSE and MODULE_DESCRIPTION macros V3 -> V4: - Compile the assertion test only when CONFIG_KUNIT_TEST is set to 'y', as it is done for the string-stream test. It is necessary since functions from the string-stream are not exported into the public namespace, and therefore they are not accessible when linking and loading the test module. include/kunit/assert.h | 11 ++ lib/kunit/Makefile | 1 + lib/kunit/assert.c | 24 ++- lib/kunit/assert_test.c | 391 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 419 insertions(+), 8 deletions(-) create mode 100644 lib/kunit/assert_test.c diff --git a/include/kunit/assert.h b/include/kunit/assert.h index 24c2b9fa61e8..7e7490a74b13 100644 --- a/include/kunit/assert.h +++ b/include/kunit/assert.h @@ -218,4 +218,15 @@ void kunit_mem_assert_format(const struct kunit_assert *assert, const struct va_format *message, struct string_stream *stream); +#if IS_ENABLED(CONFIG_KUNIT) +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream); +bool is_literal(const char *text, long long value); +bool is_str_literal(const char *text, const char *value); +void kunit_assert_hexdump(struct string_stream *stream, + const void *buf, + const void *compared_buf, + const size_t len); +#endif + #endif /* _KUNIT_ASSERT_H */ diff --git a/lib/kunit/Makefile b/lib/kunit/Makefile index 309659a32a78..900e6447c8e8 100644 --- a/lib/kunit/Makefile +++ b/lib/kunit/Makefile @@ -22,6 +22,7 @@ obj-$(CONFIG_KUNIT_TEST) += kunit-test.o # string-stream-test compiles built-in only. ifeq ($(CONFIG_KUNIT_TEST),y) obj-$(CONFIG_KUNIT_TEST) += string-stream-test.o +obj-$(CONFIG_KUNIT_TEST) += assert_test.o endif obj-$(CONFIG_KUNIT_EXAMPLE_TEST) += kunit-example-test.o diff --git a/lib/kunit/assert.c b/lib/kunit/assert.c index dd1d633d0fe2..382eb409d34b 100644 --- a/lib/kunit/assert.c +++ b/lib/kunit/assert.c @@ -7,6 +7,7 @@ */ #include <kunit/assert.h> #include <kunit/test.h> +#include <kunit/visibility.h> #include "string-stream.h" @@ -30,12 +31,14 @@ void kunit_assert_prologue(const struct kunit_loc *loc, } EXPORT_SYMBOL_GPL(kunit_assert_prologue); -static void kunit_assert_print_msg(const struct va_format *message, - struct string_stream *stream) +VISIBLE_IF_KUNIT +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream) { if (message->fmt) string_stream_add(stream, "\n%pV", message); } +EXPORT_SYMBOL_IF_KUNIT(kunit_assert_print_msg); void kunit_fail_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -89,7 +92,7 @@ void kunit_ptr_not_err_assert_format(const struct kunit_assert *assert, EXPORT_SYMBOL_GPL(kunit_ptr_not_err_assert_format); /* Checks if `text` is a literal representing `value`, e.g. "5" and 5 */ -static bool is_literal(const char *text, long long value) +VISIBLE_IF_KUNIT bool is_literal(const char *text, long long value) { char *buffer; int len; @@ -110,6 +113,7 @@ static bool is_literal(const char *text, long long value) return ret; } +EXPORT_SYMBOL_IF_KUNIT(is_literal); void kunit_binary_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -166,7 +170,7 @@ EXPORT_SYMBOL_GPL(kunit_binary_ptr_assert_format); /* Checks if KUNIT_EXPECT_STREQ() args were string literals. * Note: `text` will have ""s where as `value` will not. */ -static bool is_str_literal(const char *text, const char *value) +VISIBLE_IF_KUNIT bool is_str_literal(const char *text, const char *value) { int len; @@ -178,6 +182,7 @@ static bool is_str_literal(const char *text, const char *value) return strncmp(text + 1, value, len - 2) == 0; } +EXPORT_SYMBOL_IF_KUNIT(is_str_literal); void kunit_binary_str_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -208,10 +213,11 @@ EXPORT_SYMBOL_GPL(kunit_binary_str_assert_format); /* Adds a hexdump of a buffer to a string_stream comparing it with * a second buffer.

[PATCH v1 0/7] mm: workingset reporting

by Yuanchu Xie

Changes from RFC v3 -> PATCH v1: - Updated selftest to use ksft_print_msg instead of fprintf(stderr, ...) (Muhammad Usama Anjum) - Included more detail in patch skipping pmd_young with force_scan (Huang, Ying) - Deferred reaccess histogram as a followup - Removed per-memcg page age interval configs for simplicity Changes from RFC v2 -> RFC v3: - Update to v6.8 - Added an aging kernel thread (gated behind config) - Added basic selftests for sysfs interface files - Track swapped out pages for reaccesses - Refactoring and cleanup - Dropped the virtio-balloon extension to make things manageable Changes from RFC v1 -> RFC v2: - Refactored the patchs into smaller pieces - Renamed interfaces and functions from wss to wsr (Working Set Reporting) - Fixed build errors when CONFIG_WSR is not set - Changed working_set_num_bins to u8 for virtio-balloon - Added support for per-NUMA node reporting for virtio-balloon [rfc v1] https://lore.kernel.org/linux-mm/20230509185419.1088297-1-yuanchu@google.co… [rfc v2] https://lore.kernel.org/linux-mm/20230621180454.973862-1-yuanchu@google.com/ [rfc v3] https://lore.kernel.org/linux-mm/20240327213108.2384666-1-yuanchu@google.co… This patch series provides workingset reporting of user pages in lruvecs, of which coldness can be tracked by accessed bits and fd references. However, the concept of workingset applies generically to all types of memory, which could be kernel slab caches, discardable userspace caches (databases), or CXL.mem. Therefore, data sources might come from slab shrinkers, device drivers, or the userspace. IMO, the kernel should provide a set of workingset interfaces that should be generic enough to accommodate the various use cases, and be extensible to potential future use cases. The current proposed interfaces are not sufficient in that regard, but I would like to start somewhere, solicit feedback, and iterate. Use cases ========== Job scheduling On overcommitted hosts, workingset information allows the job scheduler to right-size each job and land more jobs on the same host or NUMA node, and in the case of a job with increasing workingset, policy decisions can be made to migrate other jobs off the host/NUMA node, or oom-kill the misbehaving job. If the job shape is very different from the machine shape, knowing the workingset per-node can also help inform page allocation policies. Proactive reclaim Workingset information allows the a container manager to proactively reclaim memory while not impacting a job's performance. While PSI may provide a reactive measure of when a proactive reclaim has reclaimed too much, workingset reporting allows the policy to be more accurate and flexible. Ballooning (similar to proactive reclaim) While this patch series does not extend the virtio-balloon device, balloon policies benefit from workingset to more precisely determine the size of the memory balloon. On desktops/laptops/mobile devices where memory is scarce and overcommitted, the balloon sizing in multiple VMs running on the same device can be orchestrated with workingset reports from each one. Promotion/Demotion Similar to proactive reclaim, a workingset report enables demotion to a slower tier of memory. For promotion, the workingset report interfaces need to be extended to report hotness and gather hotness information from the devices[1]. [1] https://www.opencompute.org/documents/ocp-cms-hotness-tracking-requirements… Sysfs and Cgroup Interfaces ========== The interfaces are detailed in the patches that introduce them. The main idea here is we break down the workingset per-node per-memcg into time intervals (ms), e.g. 1000 anon=137368 file=24530 20000 anon=34342 file=0 30000 anon=353232 file=333608 40000 anon=407198 file=206052 9223372036854775807 anon=4925624 file=892892 I realize this does not generalize well to hotness information, but I lack the intuition for an abstraction that presents hotness in a useful way. Please advise. Implementation ========== Currently, the reporting of user pages is based off of MGLRU, and therefore requires CONFIG_LRU_GEN=y. We would benefit from more MGLRU generations for a more fine-grained workingset report. I will make the generation count configurable in the next version. The workingset reporting mechanism is gated behind CONFIG_WORKINGSET_REPORT, and the aging thread is behind CONFIG_WORKINGSET_REPORT_AGING.

[PATCH net] selftests/net: use tc rule to filter the na packet

by Hangbin Liu

Test arp_ndisc_untracked_subnets use tcpdump to filter the unsolicited and untracked na messages. It set -e before calling tcpdump. But if tcpdump filters 0 packet, it will return none zero, and cause the script to exit. Instead of using slow tcpdump to capture packets, let's using tc rule to filter out the na message. At the same time, fix function setup_v6 which only needs one parameter. Move all the related helpers from forwarding lib.sh to net lib.sh. Fixes: 0ea7b0a454ca ("selftests: net: arp_ndisc_untracked_subnets: test for arp_accept and accept_untracked_na") Signed-off-by: Hangbin Liu <liuhangbin(a)gmail.com> --- Hi Jakub, would you please help check if this fix the arp_ndisc_untracked_subnets flake issue on debug kernel?

[PATCH v6] lib: add basic KUnit test for lib/math

by Daniel Latypov

Add basic test coverage for files that don't require any config options: * part of math.h (what seem to be the most commonly used macros) * gcd.c * lcm.c * int_sqrt.c * reciprocal_div.c (Ignored int_pow.c since it's a simple textbook algorithm.) These tests aren't particularly interesting, but they * provide short and simple examples of parameterized tests * provide a place to add tests for any new files in this dir * are written so adding new test cases to cover edge cases should be easy * looking at code coverage, we hit all the branches in the .c files Signed-off-by: Daniel Latypov <dlatypov(a)google.com> Reviewed-by: David Gow <davidgow(a)google.com> --- Changes since v5: * add in test cases for roundup/rounddown * address misc comments from David Changes since v4: * add in test cases for some math.h macros (abs, round_up/round_down, div_round_down/closest) * use parameterized testing less to keep things terser Changes since v3: * fix `checkpatch.pl --strict` warnings * add test cases for gcd(0,0) and lcm(0,0) * minor: don't test both gcd(a,b) and gcd(b,a) when a == b Changes since v2: mv math_test.c => math_kunit.c Changes since v1: * Rebase and rewrite to use the new parameterized testing support. * misc: fix overflow in literal and inline int_sqrt format string. * related: commit 1f0e943df68a ("Documentation: kunit: provide guidance for testing many inputs") was merged explaining the patterns shown here. * there's an in-flight patch to update it for parameterized testing. --- lib/math/Kconfig | 12 ++ lib/math/Makefile | 2 + lib/math/math_kunit.c | 291 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 305 insertions(+) create mode 100644 lib/math/math_kunit.c diff --git a/lib/math/Kconfig b/lib/math/Kconfig index f19bc9734fa7..a974d4db0f9c 100644 --- a/lib/math/Kconfig +++ b/lib/math/Kconfig @@ -15,3 +15,15 @@ config PRIME_NUMBERS config RATIONAL bool + +config MATH_KUNIT_TEST + tristate "KUnit test for lib/math and math.h" if !KUNIT_ALL_TESTS + depends on KUNIT + default KUNIT_ALL_TESTS + help + This builds unit tests for lib/math and math.h. + + For more information on KUnit and unit tests in general, please refer + to the KUnit documentation in Documentation/dev-tools/kunit/. + + If unsure, say N. diff --git a/lib/math/Makefile b/lib/math/Makefile index be6909e943bd..30abb7a8d564 100644 --- a/lib/math/Makefile +++ b/lib/math/Makefile @@ -4,3 +4,5 @@ obj-y += div64.o gcd.o lcm.o int_pow.o int_sqrt.o reciprocal_div.o obj-$(CONFIG_CORDIC) += cordic.o obj-$(CONFIG_PRIME_NUMBERS) += prime_numbers.o obj-$(CONFIG_RATIONAL) += rational.o + +obj-$(CONFIG_MATH_KUNIT_TEST) += math_kunit.o diff --git a/lib/math/math_kunit.c b/lib/math/math_kunit.c new file mode 100644 index 000000000000..556c23b17c3c --- /dev/null +++ b/lib/math/math_kunit.c @@ -0,0 +1,291 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Simple KUnit suite for math helper funcs that are always enabled. + * + * Copyright (C) 2020, Google LLC. + * Author: Daniel Latypov <dlatypov(a)google.com> + */ + +#include <kunit/test.h> +#include <linux/gcd.h> +#include <linux/kernel.h> +#include <linux/lcm.h> +#include <linux/reciprocal_div.h> + +static void abs_test(struct kunit *test) +{ + KUNIT_EXPECT_EQ(test, abs((char)0), (char)0);

[PATCH v6 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH v4 00/30] 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. Hence I would like to request review from someone familiar with locking to make sure that the usage of low-level kernel primitives is correct and that the wait queues work as intended, and to that end I've CC'd the locking maintainers. == 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 27/27 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 v3: * Add .gitignore and use KHDR_INCLUDES in selftest build files, per Muhammad Usama Anjum. * Try to explain why we are rolling our own primitives a little better, per Greg Kroah-Hartman. * Link to v3: https://lore.kernel.org/lkml/20240329000621.148791-1-zfigura@codeweavers.co… * Link to v2: https://lore.kernel.org/lkml/20240219223833.95710-1-zfigura@codeweavers.com/ * Link to v1: https://lore.kernel.org/lkml/20240214233645.9273-1-zfigura@codeweavers.com/ * 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 (27): 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. 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.

[RFC PATCH 0/4] selftests/binderfs: Fixes to binderfs_test

by Abhinav Saxena

Hi everyone, My name is Abhinav Saxena. I am a graduate student at the University of Calgary. This is my first patch series for the Linux kernel. I am applying for the "Linux kernel Bug Fixing Summer Unpaid 2024". Apologies in advance if I made any trivial mistakes :) This patch mainly includes issues reported by checkpatch.pl. The changes include: - Running clang-format on `binderfs_test.c` to fix formatting issues. - Updates the macro close_prot_errno_disarm macro. Testing: I tested patches on my local machine (ARM64 ubuntu) with checkpatch.pl and running the selftests. Best, Abhinav Abhinav Saxena (4): run clang-format on bindergfs test update close_prot_errno_disarm macro to do{...}while(false) structure for safety Macro argument 'fd' may be better as '(fd)' to avoid precedence issues add missing a blank line after declarations; fix alignment formatting .../filesystems/binderfs/binderfs_test.c | 204 +++++++++++------- 1 file changed, 126 insertions(+), 78 deletions(-) -- 2.34.1

[PATCH v4 00/11] Add support for a few Zc* extensions as well as Zcmop

by Clément Léger

Add support for (yet again) more RVA23U64 missing extensions. Add support for Zcmop, Zca, Zcf, Zcd and Zcb extensions isa string parsing, hwprobe and kvm support. Zce, Zcmt and Zcmp extensions have been left out since they target microcontrollers/embedded CPUs and are not needed by RVA23U64. Since Zc* extensions states that C implies Zca, Zcf (if F and RV32), Zcd (if D), this series modifies the way ISA string is parsed and now does it in two phases. First one parses the string and the second one validates it for the final ISA description. This series is based on the Zimop one [1]. An additional fix [2] should be applied to correctly test that series.

[PATCH net v2] selftests: net: kill smcrouted in the cleanup logic in amt.sh

[PATCH 6.6.y] kselftest: Add a ksft_perror() helper

by Edward Liaw

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 907f33028871fa7c9a3db1efd467b78ef82cce20 ] The standard library perror() function provides a convenient way to print an error message based on the current errno but this doesn't play nicely with KTAP output. Provide a helper which does an equivalent thing in a KTAP compatible format. nolibc doesn't have a strerror() and adding the table of strings required doesn't seem like a good fit for what it's trying to do so when we're using that only print the errno.

[PATCH v1 0/4] add tests to verify IFS (In Field Scan) driver functionality

by Pengfei Xu

To verify IFS (In Field Scan [1]) driver functionality, add the following 6 test cases: 1. Verify that IFS sysfs entries are created after loading the IFS module 2. Check if loading an invalid IFS test image fails and loading a valid one succeeds 3. Perform IFS scan test on each CPU using all the available image files 4. Perform IFS scan with first test image file on a random CPU for 3 rounds 5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU 6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds These are not exhaustive, but some minimal test runs to check various parts of the driver. Some negative tests are also included.

[PATCH v3] kunit: Cover 'assert.c' with tests

by Ivan Orlov

There are multiple assertion formatting functions in the `assert.c` file, which are not covered with tests yet. Implement the KUnit test for these functions. The test consists of 11 test cases for the following functions: 1) 'is_literal' 2) 'is_str_literal' 3) 'kunit_assert_prologue', test case for multiple assert types 4) 'kunit_assert_print_msg' 5) 'kunit_unary_assert_format' 6) 'kunit_ptr_not_err_assert_format' 7) 'kunit_binary_assert_format' 8) 'kunit_binary_ptr_assert_format' 9) 'kunit_binary_str_assert_format' 10) 'kunit_assert_hexdump' 11) 'kunit_mem_assert_format' The test aims at maximizing the branch coverage for the assertion formatting functions. As you can see, it covers some of the static helper functions as well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT' and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the corresponding definitions to `assert.h`. Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to how it is done for the string stream test. Signed-off-by: Ivan Orlov <ivan.orlov0322(a)gmail.com> --- V1 -> V2: - Check the output from the string stream for containing the key parts instead of comparing the results with expected strings char by char, as it was suggested by Rae Moar <rmoar(a)google.com>. Define two macros to make it possible (ASSERT_TEST_EXPECT_CONTAIN and ASSERT_TEST_EXPECT_NCONTAIN). - Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export them conditionally if kunit is enabled instead of including the `assert_test.c` file in the end of `assert.c`. This way we will decouple the test from the implementation (SUT). - Update the kunit_assert_hexdump test: now it checks for presense of the brackets '<>' around the non-matching bytes, instead of comparing the kunit_assert_hexdump output char by char. V2 -> V3: - Make test case array and test suite definitions static - Change the condition in `assert.h`: we should declare VISIBLE_IF_KUNIT functions in the header file when CONFIG_KUNIT is enabled, not CONFIG_KUNIT_TEST. Otherwise, if CONFIG_KUNIT_TEST is disabled, VISIBLE_IF_KUNIT functions in the `assert.c` are not static, and prototypes for them can't be found. - Add MODULE_LICENSE and MODULE_DESCRIPTION macros include/kunit/assert.h | 11 ++ lib/kunit/Makefile | 1 + lib/kunit/assert.c | 24 ++- lib/kunit/assert_test.c | 391 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 419 insertions(+), 8 deletions(-) create mode 100644 lib/kunit/assert_test.c diff --git a/include/kunit/assert.h b/include/kunit/assert.h index 24c2b9fa61e8..7e7490a74b13 100644 --- a/include/kunit/assert.h +++ b/include/kunit/assert.h @@ -218,4 +218,15 @@ void kunit_mem_assert_format(const struct kunit_assert *assert, const struct va_format *message, struct string_stream *stream); +#if IS_ENABLED(CONFIG_KUNIT) +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream); +bool is_literal(const char *text, long long value); +bool is_str_literal(const char *text, const char *value); +void kunit_assert_hexdump(struct string_stream *stream, + const void *buf, + const void *compared_buf, + const size_t len); +#endif + #endif /* _KUNIT_ASSERT_H */ diff --git a/lib/kunit/Makefile b/lib/kunit/Makefile index 309659a32a78..be7c9903936f 100644 --- a/lib/kunit/Makefile +++ b/lib/kunit/Makefile @@ -18,6 +18,7 @@ endif obj-y += hooks.o obj-$(CONFIG_KUNIT_TEST) += kunit-test.o +obj-$(CONFIG_KUNIT_TEST) += assert_test.o # string-stream-test compiles built-in only. ifeq ($(CONFIG_KUNIT_TEST),y) diff --git a/lib/kunit/assert.c b/lib/kunit/assert.c index dd1d633d0fe2..382eb409d34b 100644 --- a/lib/kunit/assert.c +++ b/lib/kunit/assert.c @@ -7,6 +7,7 @@ */ #include <kunit/assert.h> #include <kunit/test.h> +#include <kunit/visibility.h> #include "string-stream.h" @@ -30,12 +31,14 @@ void kunit_assert_prologue(const struct kunit_loc *loc, } EXPORT_SYMBOL_GPL(kunit_assert_prologue); -static void kunit_assert_print_msg(const struct va_format *message, - struct string_stream *stream) +VISIBLE_IF_KUNIT +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream) { if (message->fmt) string_stream_add(stream, "\n%pV", message); } +EXPORT_SYMBOL_IF_KUNIT(kunit_assert_print_msg); void kunit_fail_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -89,7 +92,7 @@ void kunit_ptr_not_err_assert_format(const struct kunit_assert *assert, EXPORT_SYMBOL_GPL(kunit_ptr_not_err_assert_format); /* Checks if `text` is a literal representing `value`, e.g. "5" and 5 */ -static bool is_literal(const char *text, long long value) +VISIBLE_IF_KUNIT bool is_literal(const char *text, long long value) { char *buffer; int len; @@ -110,6 +113,7 @@ static bool is_literal(const char *text, long long value) return ret; } +EXPORT_SYMBOL_IF_KUNIT(is_literal); void kunit_binary_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -166,7 +170,7 @@ EXPORT_SYMBOL_GPL(kunit_binary_ptr_assert_format); /* Checks if KUNIT_EXPECT_STREQ() args were string literals. * Note: `text` will have ""s where as `value` will not. */ -static bool is_str_literal(const char *text, const char *value) +VISIBLE_IF_KUNIT bool is_str_literal(const char *text, const char *value) { int len; @@ -178,6 +182,7 @@ static bool is_str_literal(const char *text, const char *value) return strncmp(text + 1, value, len - 2) == 0; } +EXPORT_SYMBOL_IF_KUNIT(is_str_literal); void kunit_binary_str_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -208,10 +213,11 @@ EXPORT_SYMBOL_GPL(kunit_binary_str_assert_format); /* Adds a hexdump of a buffer to a string_stream comparing it with * a second buffer.

[PATCH net-next v10 0/3] net: gro: remove network_header use, move p->{flush/flush_id} calculations to L4

by Richard Gobert

The cb fields network_offset and inner_network_offset are used instead of skb->network_header throughout GRO. These fields are then leveraged in the next commit to remove flush_id state from napi_gro_cb, and stateful code in {ipv6,inet}_gro_receive which may be unnecessarily complicated due to encapsulation support in GRO. These fields are checked in L4 instead. 3rd patch adds tests for different flush_id flows in GRO. v9 -> v10: - rebased on latest net-next - improved code readability in inet_gro_flush - v9: https://lore.kernel.org/all/20240507162349.130277-1-richardbgobert@gmail.co… v8 -> v9: - rename skb_gro_network_offset to skb_gro_receive_network_offset for clarification - improved code readability - v8: https://lore.kernel.org/all/20240412155533.115507-1-richardbgobert@gmail.co… v7 -> v8: - Remove network_header use in gro - Re-send commits after the dependent patch to net was applied - v7: https://lore.kernel.org/all/20240412155533.115507-1-richardbgobert@gmail.co… v6 -> v7: - Moved bug fixes to a separate submission in net - Added UDP fwd benchmark - v6: https://lore.kernel.org/all/20240410153423.107381-1-richardbgobert@gmail.co… v5 -> v6: - Write inner_network_offset in vxlan and geneve - Ignore is_atomic when DF=0 - v5: https://lore.kernel.org/all/20240408141720.98832-1-richardbgobert@gmail.com/ v4 -> v5: - Add 1st commit - flush id checks in udp_gro_receive segment which can be backported by itself - Add TCP measurements for the 5th commit - Add flush id tests to ensure flush id logic is preserved in GRO - Simplify gro_inet_flush by removing a branch - v4: https://lore.kernel.org/all/202420325182543.87683-1-richardbgobert@gmail.co… v3 -> v4: - Fix code comment and commit message typos - v3: https://lore.kernel.org/all/f939c84a-2322-4393-a5b0-9b1e0be8ed8e@gmail.com/ v2 -> v3: - Use napi_gro_cb instead of skb->{offset} - v2: https://lore.kernel.org/all/2ce1600b-e733-448b-91ac-9d0ae2b866a4@gmail.com/ v1 -> v2: - Pass p_off in *_gro_complete to fix UDP bug - Remove more conditionals and memory fetches from inet_gro_flush - v1: https://lore.kernel.org/netdev/e1d22505-c5f8-4c02-a997-64248480338b@gmail.c… Richard Gobert (3): net: gro: use cb instead of skb->network_header net: gro: move L3 flush checks to tcp_gro_receive and udp_gro_receive_segment selftests/net: add flush id selftests include/net/gro.h | 85 +++++++++++++++--- net/core/gro.c | 3 - net/ipv4/af_inet.c | 45 +--------- net/ipv4/tcp_offload.c | 20 ++--- net/ipv4/udp_offload.c | 9 +- net/ipv6/ip6_offload.c | 16 +--- net/ipv6/tcpv6_offload.c | 3 +- tools/testing/selftests/net/gro.c | 138 ++++++++++++++++++++++++++++++ 8 files changed, 224 insertions(+), 95 deletions(-) -- 2.36.1

[RFC PATCH v2] Cleaning up the KVM clock mess

by David Woodhouse

Clean up the KVM clock mess somewhat so that it is either based on the guest TSC ("master clock" mode), or on the host CLOCK_MONOTONIC_RAW in cases where the TSC isn't usable. Eliminate the third variant where it was based directly on the *host* TSC, due to bugs in e.g. __get_kvmclock(). Kill off the last vestiges of the KVM clock being based on CLOCK_MONOTONIC instead of CLOCK_MONOTONIC_RAW and thus being subject to NTP skew. Fix up migration support to allow the KVM clock to be saved/restored as an arithmetic function of the guest TSC, since that's what it actually is in the *common* case so it can be migrated precisely. Or at least to within ±1 ns which is good enough, as discussed in https://lore.kernel.org/kvm/c8dca08bf848e663f192de6705bf04aa3966e856.camel@… In v2 of this series, TSC synchronization is improved and simplified a bit too, and we allow masterclock mode to be used even when the guest TSCs are out of sync, as long as they're running at the same *rate*. The different *offset* shouldn't matter. And the kvm_get_time_scale() function annoyed me by being entirely opaque, so I studied it until my brain hurt and then added some comments. In v2 I also dropped the commits which were removing the periodic clock syncs. Those are going to be needed still but *only* for non-masterclock mode, which I'll do next. Along with ensuring that a masterclock update while already in masterclock mode doesn't jump the clock, and just does the same as KVM_SET_CLOCK_GUEST does to preserve it. Needs a *lot* more testing. I think I'm almost done refactoring the code, so should focus on building up the tests next. (I do still hate that we're abusing KVM_GET_CLOCK just to get the tuple of {host_tsc, CLOCK_REALTIME} without even *caring* about the eponymous KVM clock. Especially as this information is (a) fundamentally what the vDSO gettimeofday() exposes to us anyway, (b) using CLOCK_REALTIME not TAI, (c) not available on other platforms, for example for migrating the Arm arch counter.) David Woodhouse (13): KVM: x86/xen: Do not corrupt KVM clock in kvm_xen_shared_info_init() KVM: x86: Improve accuracy of KVM clock when TSC scaling is in force KVM: x86: Explicitly disable TSC scaling without CONSTANT_TSC KVM: x86: Add KVM_VCPU_TSC_SCALE and fix the documentation on TSC migration KVM: x86: Avoid NTP frequency skew for KVM clock on 32-bit host KVM: x86: Fix KVM clock precision in __get_kvmclock() KVM: x86: Fix software TSC upscaling in kvm_update_guest_time() KVM: x86: Simplify and comment kvm_get_time_scale() KVM: x86: Remove implicit rdtsc() from kvm_compute_l1_tsc_offset() KVM: x86: Improve synchronization in kvm_synchronize_tsc() KVM: x86: Kill cur_tsc_{nsec,offset,write} fields KVM: x86: Allow KVM master clock mode when TSCs are offset from each other KVM: x86: Factor out kvm_use_master_clock() Jack Allister (2): KVM: x86: Add KVM_[GS]ET_CLOCK_GUEST for accurate KVM clock migration KVM: selftests: Add KVM/PV clock selftest to prove timer correction Documentation/virt/kvm/api.rst | 37 ++ Documentation/virt/kvm/devices/vcpu.rst | 115 +++- arch/x86/include/asm/kvm_host.h | 15 +- arch/x86/include/uapi/asm/kvm.h | 6 + arch/x86/kvm/svm/svm.c | 3 +- arch/x86/kvm/vmx/vmx.c | 2 +- arch/x86/kvm/x86.c | 687 +++++++++++++++------- arch/x86/kvm/xen.c | 4 +- include/uapi/linux/kvm.h | 3 + tools/testing/selftests/kvm/Makefile | 1 + tools/testing/selftests/kvm/x86_64/pvclock_test.c | 192 ++++++ 11 files changed, 822 insertions(+), 243 deletions(-)

[PATCH] selftests/mm: compaction_test: Fix trivial test pass on Aarch64 when nr_hugepages = 0

by Dev Jain

Currently, if at runtime we are not able to allocate a huge page, the test will trivially pass on Aarch64 due to no exception being raised on division by zero while computing compaction_index. Fix that by checking for nr_hugepages == 0. Anyways, in general, avoid a division by zero by exiting the program beforehand. While at it, fix a typo.

[PATCH AUTOSEL 6.1 08/25] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF

by Sasha Levin

From: Oliver Upton <oliver.upton(a)linux.dev> [ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ] Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid. Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.

[PATCH v3 00/68] Define _GNU_SOURCE for sources using

by Edward Liaw

Centralizes the definition of _GNU_SOURCE into KHDR_INCLUDES and removes redefinitions of _GNU_SOURCE from source code. 809216233555 ("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler. v1: https://lore.kernel.org/linux-kselftest/20240430235057.1351993-1-edliaw@goo… v2: https://lore.kernel.org/linux-kselftest/20240507214254.2787305-1-edliaw@goo… - Add -D_GNU_SOURCE to KHDR_INCLUDES so that it is in a single location. - Remove #define _GNU_SOURCE from source code to resolve redefinition warnings. v3: - Rebase onto linux-next. - Split patches by directory. - Add -D_GNU_SOURCE directly to CFLAGS in lib.mk. - Delete additional _GNU_SOURCE definitions from source code in linux-next. - Delete additional -D_GNU_SOURCE flags from Makefiles.

[PATCH bpf-next] selftests/bpf: Free strdup memory in xdp_hw_metadata

by Geliang Tang

From: Geliang Tang <tanggeliang(a)kylinos.cn> The strdup() function returns a pointer to a new string which is a duplicate of the string "ifname". Memory for the new string is obtained with malloc(), and need to be freed with free(). This patch adds this missing "free(saved_hwtstamp_ifname)" in cleanup() to avoid a potential memory leak in xdp_hw_metadata.c.

[PATCH v1 bpf-next 00/17] Retire progs/test_sock_addr.c

by Jordan Rife

This patch series migrates remaining tests from bpf/test_sock_addr.c to prog_tests/sock_addr.c and progs/verifier_sock_addr.c in order to fully retire the old-style test program and expands test coverage to test previously untested scenarios related to sockaddr hooks. This is a continuation of the work started recently during the expansion of prog_tests/sock_addr.c. Link: https://lore.kernel.org/bpf/20240429214529.2644801-1-jrife@google.com/T/#u ======= Patches ======= * Patch 1 moves tests that check valid return values for recvmsg hooks into progs/verifier_sock_addr.c, a new addition to the verifier test suite. * Patches 2-5 lay the groundwork for test migration, enabling prog_tests/sock_addr.c to handle more test dimensions. * Patches 6-11 move existing tests to prog_tests/sock_addr.c. * Patch 12 removes some redundant test cases. * Patches 14-17 expand on existing test coverage.

[PATCH net-next v2] selftests: net: local_termination: annotate the expected failures

by Jakub Kicinski

Vladimir said when adding this test: The bridge driver fares particularly badly [...] mainly because it does not implement IFF_UNICAST_FLT. See commit 90b9566aa5cd ("selftests: forwarding: add a test for local_termination.sh"). We don't want to hide the known gaps, but having a test which always fails prevents us from catching regressions. Report the cases we know may fail as XFAIL.

[PATCH bpf-next 0/4] selftests/bpf: new MPTCP subflow subtest & improvements

by Matthieu Baerts (NGI0)

In this series from Geliang, modifying MPTCP BPF selftests, we have: - SIGINT support - A new macro to reduce duplicated code - A new MPTCP subflow BPF program setting socket options per subflow: it looks better to have this old test program in the BPF selftests to track regressions and to serve as example. Note: Nicolas is no longer working for Tessares, but he did this work while working for them, and his email address is no longer available. - A new MPTCP BPF subtest validating the new BPF program.

[PATCH net-next 1/2] selftests: net: fix timestamp not arriving in cmsg_time.sh

by Jakub Kicinski

On slow machines the SND timestamp sometimes doesn't arrive before we quit. The test only waits as long as the packet delay, so it's easy for a race condition to happen. Double the wait but do a bit of polling, once the SND timestamp arrives there's no point to wait any longer. This fixes the "TXTIME abs" failures on debug kernels, like: Case ICMPv4 - TXTIME abs returned '', expected 'OK' Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> --- CC: shuah(a)kernel.org CC: linux-kselftest(a)vger.kernel.org --- tools/testing/selftests/net/cmsg_sender.c | 20 +++++++++++++++----- 1 file changed, 15 insertions(+), 5 deletions(-) diff --git a/tools/testing/selftests/net/cmsg_sender.c b/tools/testing/selftests/net/cmsg_sender.c index c79e65581dc3..f25268504937 100644 --- a/tools/testing/selftests/net/cmsg_sender.c +++ b/tools/testing/selftests/net/cmsg_sender.c @@ -333,16 +333,17 @@ static const char *cs_ts_info2str(unsigned int info) return "unknown"; } -static void +static unsigned long cs_read_cmsg(int fd, struct msghdr *msg, char *cbuf, size_t cbuf_sz) { struct sock_extended_err *see; struct scm_timestamping *ts; + unsigned int ts_seen = 0; struct cmsghdr *cmsg; int i, err; if (!opt.ts.ena) - return; + return 0; msg->msg_control = cbuf; msg->msg_controllen = cbuf_sz; @@ -396,8 +397,11 @@ cs_read_cmsg(int fd, struct msghdr *msg, char *cbuf, size_t cbuf_sz) printf(" %5s ts%d %lluus\n", cs_ts_info2str(see->ee_info), i, rel_time); + ts_seen |= 1 << see->ee_info; } } + + return ts_seen; } static void ca_set_sockopts(int fd) @@ -509,10 +513,16 @@ int main(int argc, char *argv[]) err = ERN_SUCCESS; if (opt.ts.ena) { - /* Make sure all timestamps have time to loop back */ - usleep(opt.txtime.delay); + unsigned long seen; + int i; - cs_read_cmsg(fd, &msg, cbuf, sizeof(cbuf)); + /* Make sure all timestamps have time to loop back */ + for (i = 0; i < 40; i++) { + seen = cs_read_cmsg(fd, &msg, cbuf, sizeof(cbuf)); + if (seen & (1 << SCM_TSTAMP_SND)) + break; + usleep(opt.txtime.delay / 20); + } } err_out: -- 2.45.0

[PATCH net] selftests: net: move amt to socat for better compatibility

by Jakub Kicinski

The test seems to expect that nc will exit after the first received message. This is not the case with Ncat 7.94. There are multiple versions of nc out there, switch to socat for better compatibility. Tell socat to exit after 128 bytes and pad the message. Since the test sets -e make sure we don't set exit code (|| true) and print the pass / fail rather then silently moving over the test and just setting non-zero exit code with no output indicating what failed.

[PATCH net-next v9 0/3] net: gro: remove network_header use, move p->{flush/flush_id} calculations to L4

by Richard Gobert

The cb fields network_offset and inner_network_offset are used instead of skb->network_header throughout GRO. These fields are then leveraged in the next commit to remove flush_id state from napi_gro_cb, and stateful code in {ipv6,inet}_gro_receive which may be unnecessarily complicated due to encapsulation support in GRO. These fields are checked in L4 instead. 3rd patch adds tests for different flush_id flows in GRO. v8 -> v9: - rename skb_gro_network_offset to skb_gro_receive_network_offset for clarification - improved code readability in tests and gro_network_flush functions - v8: https://lore.kernel.org/all/20240506093550.128210-1-richardbgobert@gmail.co… v7 -> v8: - Remove network_header use in gro - Re-send commits after the dependent patch to net was applied - v7: https://lore.kernel.org/all/20240412155533.115507-1-richardbgobert@gmail.co… v6 -> v7: - Moved bug fixes to a separate submission in net - Added UDP fwd benchmark - v6: https://lore.kernel.org/all/20240410153423.107381-1-richardbgobert@gmail.co… v5 -> v6: - Write inner_network_offset in vxlan and geneve - Ignore is_atomic when DF=0 - v5: https://lore.kernel.org/all/20240408141720.98832-1-richardbgobert@gmail.com/ v4 -> v5: - Add 1st commit - flush id checks in udp_gro_receive segment which can be backported by itself - Add TCP measurements for the 5th commit - Add flush id tests to ensure flush id logic is preserved in GRO - Simplify gro_inet_flush by removing a branch - v4: https://lore.kernel.org/all/202420325182543.87683-1-richardbgobert@gmail.co… v3 -> v4: - Fix code comment and commit message typos - v3: https://lore.kernel.org/all/f939c84a-2322-4393-a5b0-9b1e0be8ed8e@gmail.com/ v2 -> v3: - Use napi_gro_cb instead of skb->{offset} - v2: https://lore.kernel.org/all/2ce1600b-e733-448b-91ac-9d0ae2b866a4@gmail.com/ v1 -> v2: - Pass p_off in *_gro_complete to fix UDP bug - Remove more conditionals and memory fetches from inet_gro_flush - v1: https://lore.kernel.org/netdev/e1d22505-c5f8-4c02-a997-64248480338b@gmail.c… Richard Gobert (3): net: gro: use cb instead of skb->network_header net: gro: move L3 flush checks to tcp_gro_receive and udp_gro_receive_segment selftests/net: add flush id selftests include/net/gro.h | 87 ++++++++++++++++--- net/core/gro.c | 3 - net/ipv4/af_inet.c | 45 +--------- net/ipv4/tcp_offload.c | 20 ++--- net/ipv4/udp_offload.c | 10 +-- net/ipv6/ip6_offload.c | 16 +--- net/ipv6/tcpv6_offload.c | 3 +- tools/testing/selftests/net/gro.c | 138 ++++++++++++++++++++++++++++++ 8 files changed, 227 insertions(+), 95 deletions(-) -- 2.36.1

[PATCH] selftests/resctrl: fix clang build warnings related to abs(), labs() calls

by John Hubbard

[PATCH v2 0/2] Selftests: Fix compilation warnings due to missing _GNU_SOURCE definition

by Tao Su

Since kselftest_harness.h introduces asprintf()[1], many selftests have compilation warnings or errors due to missing _GNU_SOURCE definitions. The issue stems from a lack of a LINE_MAX definition in Android (see commit 38c957f07038), which is the reason why asprintf() was introduced. We tried adding _GNU_SOURCE definitions to more selftests to fix, but asprintf() may continue to cause problems, and since it is quite late in the 6.9 cycle, we would like to revert 809216233555 first to provide testing for forks[2].

[PATCH v2] selftests/mqueue: fix 5 warnings about signed/unsigned mismatches

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about several cases of using a signed integer for the priority argument to mq_receive(3), which expects an unsigned int. Fix this by declaring the type as unsigned int in all cases. Also, both input and output priority are unsigned, per the man pages, so let's change the type of both priorities throughout, even though clang did not warn about the prio_out variable. Also, add an argument name to test->func(), in order to address another warning from clang.

[PATCH net] selftests: net: avoid waiting for server in amt.sh forever when it fails.

by Taehee Yoo

In the forwarding testcase, it opens a server and a client with the nc. The server receives the correct message from NC, it prints OK. The server prints FAIL if it receives the wrong message from the client. But If the server can't receive any message, it will not close so the amt.sh waits forever. There are several reasons. 1. crash of smcrouted. 2. Send a message from the client to the server before the server is up. To avoid this problem, the server waits only for 10 seconds. The client sends messages for 10 seconds. If the server is successfully closed, it kills the client.

[PATCH v4 0/9] Support Zve32[xf] and Zve64[xfd] Vector subextensions

by Andy Chiu

The series composes of two parts. The first part provides a quick fix for the issue on a recent thread[1]. The issue happens when a platform has ununified vector register length across multiple cores. Specifically, patch 1 adds a comment at a callsite of riscv_setup_vsize to clarify how vlenb is observed by the system. Patch 2 fixes the issue by failing the boot process of a secondary core if vlenb mismatches. The second part of the series provide a finer grain view of the Vector extension. Patch 3 give the obsolete ISA parser the ability to expand ISA extensions for sigle letter extensions. Patch 3, 4 introduces Zve32x, Zve32f, Zve64x, Zve64f, Zve64d for isa parsing and hwprobe. Patch 5 updates all callsites such that Vector subextensions are maximumly supported by the kernel. Two parts of the series are sent together to ease the effort of picking dependency patches. The first part can be merged independent of the second one if necessary. The series is tested on a QEMU and verified that booting, Vector programs context-switch, signal, ptrace, prctl interfaces works when we only report partial V from the ISA. Note that the signal test was performed after applying the commit c27fa53b858b ("riscv: Fix vector state restore in rt_sigreturn()") This patch should be able to apply on risc-v for-next branch on top of the commit ba5ea59f768f ("riscv: Do not save the scratch CSR during suspend") [1]: https://lore.kernel.org/all/20240228-vicinity-cornstalk-4b8eb5fe5730@spud/T… Changes in v4: - Add a patch to trigger prctl test on ZVE32X (9) - Add a patch to fix integer promotion bug in hwprobe (8) - Fix a build fail on !CONFIG_RISCV_ISA_V (7) - Add more comment in the assembly code change (2) - Link to v3: https://lore.kernel.org/r/20240318-zve-detection-v3-0-e12d42107fa8@sifive.c… Changelog v3: - Include correct maintainers and mailing list into CC. - Cleanup isa string parser code (3) - Adjust extensions order and name (4, 5) - Refine commit message (6) Changelog v2: - Update comments and commit messages (1, 2, 7) - Refine isa_exts[] lists for zve extensions (4) - Add a patch for dt-binding (5) - Make ZVE* extensions depend on has_vector(ZVE32X) (6, 7) --- --- Andy Chiu (9): riscv: vector: add a comment when calling riscv_setup_vsize() riscv: smp: fail booting up smp if inconsistent vlen is detected riscv: cpufeature: call match_isa_ext() for single-letter extensions riscv: cpufeature: add zve32[xf] and zve64[xfd] isa detection dt-bindings: riscv: add Zve32[xf] Zve64[xfd] ISA extension description riscv: hwprobe: add zve Vector subextensions into hwprobe interface riscv: vector: adjust minimum Vector requirement to ZVE32X hwprobe: fix integer promotion in RISCV_HWPROBE_EXT macro selftest: run vector prctl test for ZVE32X Documentation/arch/riscv/hwprobe.rst | 15 ++++++ .../devicetree/bindings/riscv/extensions.yaml | 30 ++++++++++++ arch/riscv/include/asm/hwcap.h | 5 ++ arch/riscv/include/asm/switch_to.h | 2 +- arch/riscv/include/asm/vector.h | 25 ++++++---- arch/riscv/include/asm/xor.h | 2 +- arch/riscv/include/uapi/asm/hwprobe.h | 7 ++- arch/riscv/kernel/cpufeature.c | 56 ++++++++++++++++++---- arch/riscv/kernel/head.S | 19 +++++--- arch/riscv/kernel/kernel_mode_vector.c | 4 +- arch/riscv/kernel/process.c | 4 +- arch/riscv/kernel/signal.c | 6 +-- arch/riscv/kernel/smpboot.c | 14 ++++-- arch/riscv/kernel/sys_hwprobe.c | 13 ++++- arch/riscv/kernel/vector.c | 15 +++--- arch/riscv/lib/uaccess.S | 2 +- .../testing/selftests/riscv/vector/vstate_prctl.c | 6 +-- 17 files changed, 174 insertions(+), 51 deletions(-) --- base-commit: ba5ea59f768f67d127b319b26ba209ff67e0d9a5 change-id: 20240318-zve-detection-50106d2da527 Best regards, -- Andy Chiu <andy.chiu(a)sifive.com>

[PATCH bpf-next 0/6] use network helpers, part 4

by Geliang Tang

From: Geliang Tang <tanggeliang(a)kylinos.cn> This patchset adds post_socket_cb pointer together with 'struct post_socket_opts cb_opts' into struct network_helper_opts to make start_server_addr() helper more flexible. With these modifications, many duplicate codes can be dropped. Patches 1-3 address Martin's comments in the previous series.

[PATCH REPOST net-next v3] selftest: epoll_busy_poll: epoll busy poll tests

by Joe Damato

Add a simple test for the epoll busy poll ioctls, using the kernel selftest harness. This test ensures that the ioctls have the expected return codes and that the kernel properly gets and sets epoll busy poll parameters. The test can be expanded in the future to do real busy polling (provided another machine to act as the client is available). Signed-off-by: Joe Damato <jdamato(a)fastly.com> --- v2 -> v3: - Added this changelog :) - Add libcap to LDLIBS. - Most other changes are in test_set_invalid: - Check if CAP_NET_ADMIN is set in the effective set before setting busy_poll_budget over NAPI_POLL_WEIGHT. The test which follows assumes CAP_NET_ADMIN. - Drop CAP_NET_ADMIN from effective set in order to ensure the ioctl fails when busy_poll_budget exceeds NAPI_POLL_WEIGHT. - Put CAP_NET_ADMIN back into the effective set afterwards. - Changed self->params.busy_poll_budget from 65535 to UINT16_MAX. - Changed the cast for params.busy_poll_usecs from unsigned int to uint32_t in the test_set_invalid case. v1 -> v2: - Rewrote completely to use kernel self test harness. tools/testing/selftests/net/.gitignore | 1 + tools/testing/selftests/net/Makefile | 3 +- tools/testing/selftests/net/epoll_busy_poll.c | 320 ++++++++++++++++++ 3 files changed, 323 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/net/epoll_busy_poll.c diff --git a/tools/testing/selftests/net/.gitignore b/tools/testing/selftests/net/.gitignore index d996a0ab0765..777cfd027076 100644 --- a/tools/testing/selftests/net/.gitignore +++ b/tools/testing/selftests/net/.gitignore @@ -5,6 +5,7 @@ bind_wildcard csum cmsg_sender diag_uid +epoll_busy_poll fin_ack_lat gro hwtstamp_config diff --git a/tools/testing/selftests/net/Makefile b/tools/testing/selftests/net/Makefile index 5befca249452..c6112d08b233 100644 --- a/tools/testing/selftests/net/Makefile +++ b/tools/testing/selftests/net/Makefile @@ -67,7 +67,7 @@ TEST_GEN_FILES += ipsec TEST_GEN_FILES += ioam6_parser TEST_GEN_FILES += gro TEST_GEN_PROGS = reuseport_bpf reuseport_bpf_cpu reuseport_bpf_numa -TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap +TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap epoll_busy_poll TEST_GEN_FILES += toeplitz TEST_GEN_FILES += cmsg_sender TEST_GEN_FILES += stress_reuseport_listen @@ -102,6 +102,7 @@ TEST_INCLUDES := forwarding/lib.sh include ../lib.mk +$(OUTPUT)/epoll_busy_poll: LDLIBS += -lcap $(OUTPUT)/reuseport_bpf_numa: LDLIBS += -lnuma $(OUTPUT)/tcp_mmap: LDLIBS += -lpthread -lcrypto $(OUTPUT)/tcp_inq: LDLIBS += -lpthread diff --git a/tools/testing/selftests/net/epoll_busy_poll.c b/tools/testing/selftests/net/epoll_busy_poll.c new file mode 100644 index 000000000000..9dd2830fd67c --- /dev/null +++ b/tools/testing/selftests/net/epoll_busy_poll.c @@ -0,0 +1,320 @@ +// SPDX-License-Identifier: GPL-2.0-or-later + +/* Basic per-epoll context busy poll test. + * + * Only tests the ioctls, but should be expanded to test two connected hosts in + * the future + */ + +#define _GNU_SOURCE + +#include <error.h> +#include <errno.h> +#include <inttypes.h> +#include <limits.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <unistd.h> + +#include <sys/capability.h> + +#include <sys/epoll.h> +#include <sys/ioctl.h> +#include <sys/socket.h> + +#include "../kselftest_harness.h" + +/* if the headers haven't been updated, we need to define some things */ +#if !defined(EPOLL_IOC_TYPE) +struct epoll_params { + uint32_t busy_poll_usecs;

[PATCH] selftests: Add _GNU_SOURCE definition when including kselftest_harness.h

by Tao Su

asprintf() is declared in stdio.h when defining _GNU_SOURCE, but stdio.h is so common that many files don’t define _GNU_SOURCE before including stdio.h, and defining _GNU_SOURCE after including stdio.h will no longer take effect. Since kselftest_harness.h introduces asprintf(), it is necessary to add _GNU_SOURCE definition in all selftests including kselftest_harness.h, otherwise, there will be warnings or even errors during compilation. There are already many selftests that define _GNU_SOURCE or put the include of kselftest_harness.h at the very beginning of the .c file, just add the _GNU_SOURCE definition in the tests that have compilation warnings.

[PATCH v2 0/5] Define _GNU_SOURCE for sources using

by Edward Liaw

809216233555 ("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler. v1: https://lore.kernel.org/linux-kselftest/20240430235057.1351993-1-edliaw@goo… v2: add -D_GNU_SOURCE to KHDR_INCLUDES so that it is in a single location. Remove #define _GNU_SOURCE from source code to resolve redefinition warnings.

[PATCH] KVM: selftests: Check API version when creating VM

by Ivan Orlov

As it is said in the docs, we should always check the KVM API version before running the KVM-based applications. Add the function which queries the current KVM API version through `ioctl` to the `kvm_util.c` file. Add a new TEST_REQUIRE statement to the `vm_open` function in order to verify the version of the KVM API before creating a VM.

[PATCH v8 0/3] KVM: selftests: aarch64: Introduce pmu_event_filter_test

by Shaoqin Huang

The test is inspired by the pmu_event_filter_test which implemented by x86. On the arm64 platform, there is the same ability to set the pmu_event_filter through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64. The series first create the helper function which can be used for the vpmu related tests. Then, it implement the test. Changelog: ---------- v7->v8: - Rebased to kvm-arm/next. - Deleted the GIC layout related staff. - Fixed the checking logic in the kvm_pmu_support_events. v6->v7: - Rebased to v6.9-rc3. v5->v6: - Rebased to v6.9-rc1. - Collect RB. - Add multiple filter test. v4->v5: - Rebased to v6.8-rc6. - Refactor the helper function, make it fine-grained and easy to be used. - Namimg improvements. - Use the kvm_device_attr_set() helper. - Make the test descriptor array readable and clean. - Delete the patch which moves the pmu related helper to vpmu.h. - Remove the kvm_supports_pmu_event_filter() function since nobody will run this on a old kernel. v3->v4: - Rebased to the v6.8-rc2. v2->v3: - Check the pmceid in guest code instead of pmu event count since different hardware may have different event count result, check pmceid makes it stable on different platform. [Eric] - Some typo fixed and commit message improved. v1->v2: - Improve the commit message. [Eric] - Fix the bug in [enable|disable]_counter. [Raghavendra & Marc] - Add the check if kvm has attr KVM_ARM_VCPU_PMU_V3_FILTER. - Add if host pmu support the test event throught pmceid0. - Split the test_invalid_filter() to another patch.

On the arm64 platform, there is the same ability to set the pmu_event_filter through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64. The series first create the helper function which can be used for the vpmu related tests. Then, it implement the test. Changelog: ---------- v6->v7: - Rebased to v6.9-rc3. v5->v6: - Rebased to v6.9-rc1. - Collect RB. - Add multiple filter test. v4->v5: - Rebased to v6.8-rc6. - Refactor the helper function, make it fine-grained and easy to be used. - Namimg improvements. - Use the kvm_device_attr_set() helper. - Make the test descriptor array readable and clean. - Delete the patch which moves the pmu related helper to vpmu.h. - Remove the kvm_supports_pmu_event_filter() function since nobody will run this on a old kernel. v3->v4: - Rebased to the v6.8-rc2. v2->v3: - Check the pmceid in guest code instead of pmu event count since different hardware may have different event count result, check pmceid makes it stable on different platform. [Eric] - Some typo fixed and commit message improved. v1->v2: - Improve the commit message. [Eric] - Fix the bug in [enable|disable]_counter. [Raghavendra & Marc] - Add the check if kvm has attr KVM_ARM_VCPU_PMU_V3_FILTER. - Add if host pmu support the test event throught pmceid0. - Split the test_invalid_filter() to another patch.

[PATCH v2] kunit: Cover 'assert.c' with tests

by Ivan Orlov

There are multiple assertion formatting functions in the `assert.c` file, which are not covered with tests yet. Implement the KUnit test for these functions. The test consists of 11 test cases for the following functions: 1) 'is_literal' 2) 'is_str_literal' 3) 'kunit_assert_prologue', test case for multiple assert types 4) 'kunit_assert_print_msg' 5) 'kunit_unary_assert_format' 6) 'kunit_ptr_not_err_assert_format' 7) 'kunit_binary_assert_format' 8) 'kunit_binary_ptr_assert_format' 9) 'kunit_binary_str_assert_format' 10) 'kunit_assert_hexdump' 11) 'kunit_mem_assert_format' The test aims at maximizing the branch coverage for the assertion formatting functions. As you can see, it covers some of the static helper functions as well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT' and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the corresponding definitions to `assert.h`. Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to how it is done for the string stream test. Signed-off-by: Ivan Orlov <ivan.orlov0322(a)gmail.com> --- V1 -> V2: - Check the output from the string stream for containing the key parts instead of comparing the results with expected strings char by char, as it was suggested by Rae Moar <rmoar(a)google.com>. Define two macros to make it possible (ASSERT_TEST_EXPECT_CONTAIN and ASSERT_TEST_EXPECT_NCONTAIN). - Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export them conditionally if kunit is enabled instead of including the `assert_test.c` file in the end of `assert.c`. This way we will decouple the test from the implementation (SUT). - Update the kunit_assert_hexdump test: now it checks for presense of the brackets '<>' around the non-matching bytes, instead of comparing the kunit_assert_hexdump output char by char. include/kunit/assert.h | 11 ++ lib/kunit/Makefile | 1 + lib/kunit/assert.c | 24 ++- lib/kunit/assert_test.c | 389 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 417 insertions(+), 8 deletions(-) create mode 100644 lib/kunit/assert_test.c diff --git a/include/kunit/assert.h b/include/kunit/assert.h index 24c2b9fa61e8..31e655abbce9 100644 --- a/include/kunit/assert.h +++ b/include/kunit/assert.h @@ -218,4 +218,15 @@ void kunit_mem_assert_format(const struct kunit_assert *assert, const struct va_format *message, struct string_stream *stream); +#if IS_ENABLED(CONFIG_KUNIT_TEST) +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream); +bool is_literal(const char *text, long long value); +bool is_str_literal(const char *text, const char *value); +void kunit_assert_hexdump(struct string_stream *stream, + const void *buf, + const void *compared_buf, + const size_t len); +#endif + #endif /* _KUNIT_ASSERT_H */ diff --git a/lib/kunit/Makefile b/lib/kunit/Makefile index 309659a32a78..be7c9903936f 100644 --- a/lib/kunit/Makefile +++ b/lib/kunit/Makefile @@ -18,6 +18,7 @@ endif obj-y += hooks.o obj-$(CONFIG_KUNIT_TEST) += kunit-test.o +obj-$(CONFIG_KUNIT_TEST) += assert_test.o # string-stream-test compiles built-in only. ifeq ($(CONFIG_KUNIT_TEST),y) diff --git a/lib/kunit/assert.c b/lib/kunit/assert.c index dd1d633d0fe2..382eb409d34b 100644 --- a/lib/kunit/assert.c +++ b/lib/kunit/assert.c @@ -7,6 +7,7 @@ */ #include <kunit/assert.h> #include <kunit/test.h> +#include <kunit/visibility.h> #include "string-stream.h" @@ -30,12 +31,14 @@ void kunit_assert_prologue(const struct kunit_loc *loc, } EXPORT_SYMBOL_GPL(kunit_assert_prologue); -static void kunit_assert_print_msg(const struct va_format *message, - struct string_stream *stream) +VISIBLE_IF_KUNIT +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream) { if (message->fmt) string_stream_add(stream, "\n%pV", message); } +EXPORT_SYMBOL_IF_KUNIT(kunit_assert_print_msg); void kunit_fail_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -89,7 +92,7 @@ void kunit_ptr_not_err_assert_format(const struct kunit_assert *assert, EXPORT_SYMBOL_GPL(kunit_ptr_not_err_assert_format); /* Checks if `text` is a literal representing `value`, e.g. "5" and 5 */ -static bool is_literal(const char *text, long long value) +VISIBLE_IF_KUNIT bool is_literal(const char *text, long long value) { char *buffer; int len; @@ -110,6 +113,7 @@ static bool is_literal(const char *text, long long value) return ret; } +EXPORT_SYMBOL_IF_KUNIT(is_literal); void kunit_binary_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -166,7 +170,7 @@ EXPORT_SYMBOL_GPL(kunit_binary_ptr_assert_format); /* Checks if KUNIT_EXPECT_STREQ() args were string literals. * Note: `text` will have ""s where as `value` will not. */ -static bool is_str_literal(const char *text, const char *value) +VISIBLE_IF_KUNIT bool is_str_literal(const char *text, const char *value) { int len; @@ -178,6 +182,7 @@ static bool is_str_literal(const char *text, const char *value) return strncmp(text + 1, value, len - 2) == 0; } +EXPORT_SYMBOL_IF_KUNIT(is_str_literal); void kunit_binary_str_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -208,10 +213,11 @@ EXPORT_SYMBOL_GPL(kunit_binary_str_assert_format); /* Adds a hexdump of a buffer to a string_stream comparing it with * a second buffer.

[RFC PATCH net-next v8 00/14] Device Memory TCP

by Mina Almasry

RFC v8: ======= Major Changes: -------------- - Fixed build error generated by patch-by-patch build. - Applied docs suggestions from Randy. RFC v7: ======= Major Changes: -------------- This revision largely rebases on top of net-next and addresses the feedback RFCv6 received from folks, namely Jakub, Yunsheng, Arnd, David, & Pavel. The series remains in RFC because the queue-API ndos defined in this series are not yet implemented. I have a GVE implementation I carry out of tree for my testing. A upstreamable GVE implementation is in the works. Aside from that, in my estimation all the patches are ready for review/merge. Please do take a look. As usual the full devmem TCP changes including the full GVE driver implementation is here: https://github.com/mina/linux/commits/tcpdevmem-v7/ Detailed changelog: - Use admin-perm in netlink API. - Addressed feedback from Jakub with regards to netlink API implementation. - Renamed devmem.c functions to something more appropriate for that file. - Improve the performance seen through the page_pool benchmark. - Fix the value definition of all the SO_DEVMEM_* uapi. - Various fixes to documentation. Perf - page-pool benchmark: --------------------------- Improved performance of bench_page_pool_simple.ko tests compared to v6: https://pastebin.com/raw/v5dYRg8L net-next base: 8 cycle fast path. RFC v6: 10 cycle fast path. RFC v7: 9 cycle fast path. RFC v7 with CONFIG_DMA_SHARED_BUFFER disabled: 8 cycle fast path, same as baseline. Perf - Devmem TCP benchmark: --------------------- Perf is about the same regardless of the changes in v7, namely the removal of the static_branch_unlikely to improve the page_pool benchmark performance: 189/200gbps bi-directional throughput with RX devmem TCP and regular TCP TX i.e. ~95% line rate. RFC v6: ======= Major Changes: -------------- This revision largely rebases on top of net-next and addresses the little feedback RFCv5 received. The series remains in RFC because the queue-API ndos defined in this series are not yet implemented. I have a GVE implementation I carry out of tree for my testing. A upstreamable GVE implementation is in the works. Aside from that, in my estimation all the patches are ready for review/merge. Please do take a look. As usual the full devmem TCP changes including the full GVE driver implementation is here: https://github.com/mina/linux/commits/tcpdevmem-v6/ This version also comes with some performance data recorded in the cover letter (see below changelog). Detailed changelog: - Rebased on top of the merged netmem_ref changes. - Converted skb->dmabuf to skb->readable (Pavel). Pavel's original suggestion was to remove the skb->dmabuf flag entirely, but when I looked into it closely, I found the issue that if we remove the flag we have to dereference the shinfo(skb) pointer to obtain the first frag to tell whether an skb is readable or not. This can cause a performance regression if it dirties the cache line when the shinfo(skb) was not really needed. Instead, I converted the skb->dmabuf flag into a generic skb->readable flag which can be re-used by io_uring 0-copy RX. - Squashed a few locking optimizations from Eric Dumazet in the RX path and the DEVMEM_DONTNEED setsockopt. - Expanded the tests a bit. Added validation for invalid scenarios and added some more coverage. Perf - page-pool benchmark: --------------------------- bench_page_pool_simple.ko tests with and without these changes: https://pastebin.com/raw/ncHDwAbn AFAIK the number that really matters in the perf tests is the 'tasklet_page_pool01_fast_path Per elem'. This one measures at about 8 cycles without the changes but there is some 1 cycle noise in some results. With the patches this regresses to 9 cycles with the changes but there is 1 cycle noise occasionally running this test repeatedly. Lastly I tried disable the static_branch_unlikely() in netmem_is_net_iov() check. To my surprise disabling the static_branch_unlikely() check reduces the fast path back to 8 cycles, but the 1 cycle noise remains. Perf - Devmem TCP benchmark: --------------------- 189/200gbps bi-directional throughput with RX devmem TCP and regular TCP TX i.e. ~95% line rate. Major changes in RFC v5: ======================== 1. Rebased on top of 'Abstract page from net stack' series and used the new netmem type to refer to LSB set pointers instead of re-using struct page. 2. Downgraded this series back to RFC and called it RFC v5. This is because this series is now dependent on 'Abstract page from net stack'[1] and the queue API. Both are removed from the series to reduce the patch # and those bits are fairly independent or pre-requisite work. 3. Reworked the page_pool devmem support to use netmem and for some more unified handling. 4. Reworked the reference counting of net_iov (renamed from page_pool_iov) to use pp_ref_count for refcounting. The full changes including the dependent series and GVE page pool support is here: https://github.com/mina/linux/commits/tcpdevmem-rfcv5/ [1] https://patchwork.kernel.org/project/netdevbpf/list/?series=810774 Major changes in v1: ==================== 1. Implemented MVP queue API ndos to remove the userspace-visible driver reset. 2. Fixed issues in the napi_pp_put_page() devmem frag unref path. 3. Removed RFC tag. Many smaller addressed comments across all the patches (patches have individual change log). Full tree including the rest of the GVE driver changes: https://github.com/mina/linux/commits/tcpdevmem-v1 Changes in RFC v3: ================== 1. Pulled in the memory-provider dependency from Jakub's RFC[1] to make the series reviewable and mergeable. 2. Implemented multi-rx-queue binding which was a todo in v2. 3. Fix to cmsg handling. The sticking point in RFC v2[2] was the device reset required to refill the device rx-queues after the dmabuf bind/unbind. The solution suggested as I understand is a subset of the per-queue management ops Jakub suggested or similar: https://lore.kernel.org/netdev/20230815171638.4c057dcd@kernel.org/ This is not addressed in this revision, because: 1. This point was discussed at netconf & netdev and there is openness to using the current approach of requiring a device reset. 2. Implementing individual queue resetting seems to be difficult for my test bed with GVE. My prototype to test this ran into issues with the rx-queues not coming back up properly if reset individually. At the moment I'm unsure if it's a mistake in the POC or a genuine issue in the virtualization stack behind GVE, which currently doesn't test individual rx-queue restart. 3. Our usecases are not bothered by requiring a device reset to refill the buffer queues, and we'd like to support NICs that run into this limitation with resetting individual queues. My thought is that drivers that have trouble with per-queue configs can use the support in this series, while drivers that support new netdev ops to reset individual queues can automatically reset the queue as part of the dma-buf bind/unbind. The same approach with device resets is presented again for consideration with other sticking points addressed. This proposal includes the rx devmem path only proposed for merge. For a snapshot of my entire tree which includes the GVE POC page pool support & device memory support: https://github.com/torvalds/linux/compare/master...mina:linux:tcpdevmem-v3 [1] https://lore.kernel.org/netdev/f8270765-a27b-6ccf-33ea-cda097168d79@redhat.… [2] https://lore.kernel.org/netdev/CAHS8izOVJGJH5WF68OsRWFKJid1_huzzUK+hpKbLcL4… Changes in RFC v2: ================== The sticking point in RFC v1[1] was the dma-buf pages approach we used to deliver the device memory to the TCP stack. RFC v2 is a proof-of-concept that attempts to resolve this by implementing scatterlist support in the networking stack, such that we can import the dma-buf scatterlist directly. This is the approach proposed at a high level here[2]. Detailed changes: 1. Replaced dma-buf pages approach with importing scatterlist into the page pool. 2. Replace the dma-buf pages centric API with a netlink API. 3. Removed the TX path implementation - there is no issue with implementing the TX path with scatterlist approach, but leaving out the TX path makes it easier to review. 4. Functionality is tested with this proposal, but I have not conducted perf testing yet. I'm not sure there are regressions, but I removed perf claims from the cover letter until they can be re-confirmed. 5. Added Signed-off-by: contributors to the implementation. 6. Fixed some bugs with the RX path since RFC v1. Any feedback welcome, but specifically the biggest pending questions needing feedback IMO are: 1. Feedback on the scatterlist-based approach in general. 2. Netlink API (Patch 1 & 2). 3. Approach to handle all the drivers that expect to receive pages from the page pool (Patch 6). [1] https://lore.kernel.org/netdev/dfe4bae7-13a0-3c5d-d671-f61b375cb0b4@gmail.c… [2] https://lore.kernel.org/netdev/CAHS8izPm6XRS54LdCDZVd0C75tA1zHSu6jLVO8nzTLX… ================== * TL;DR: Device memory TCP (devmem TCP) is a proposal for transferring data to and/or from device memory efficiently, without bouncing the data to a host memory buffer. * Problem: A large amount of data transfers have device memory as the source and/or destination. Accelerators drastically increased the volume of such transfers. Some examples include: - ML accelerators transferring large amounts of training data from storage into GPU/TPU memory. In some cases ML training setup time can be as long as 50% of TPU compute time, improving data transfer throughput & efficiency can help improving GPU/TPU utilization. - Distributed training, where ML accelerators, such as GPUs on different hosts, exchange data among them. - Distributed raw block storage applications transfer large amounts of data with remote SSDs, much of this data does not require host processing. Today, the majority of the Device-to-Device data transfers the network are implemented as the following low level operations: Device-to-Host copy, Host-to-Host network transfer, and Host-to-Device copy. The implementation is suboptimal, especially for bulk data transfers, and can put significant strains on system resources, such as host memory bandwidth, PCIe bandwidth, etc. One important reason behind the current state is the kernel’s lack of semantics to express device to network transfers. * Proposal: In this patch series we attempt to optimize this use case by implementing socket APIs that enable the user to: 1. send device memory across the network directly, and 2. receive incoming network packets directly into device memory. Packet _payloads_ go directly from the NIC to device memory for receive and from device memory to NIC for transmit. Packet _headers_ go to/from host memory and are processed by the TCP/IP stack normally. The NIC _must_ support header split to achieve this. Advantages: - Alleviate host memory bandwidth pressure, compared to existing network-transfer + device-copy semantics. - Alleviate PCIe BW pressure, by limiting data transfer to the lowest level of the PCIe tree, compared to traditional path which sends data through the root complex. * Patch overview: ** Part 1: netlink API Gives user ability to bind dma-buf to an RX queue. ** Part 2: scatterlist support Currently the standard for device memory sharing is DMABUF, which doesn't generate struct pages. On the other hand, networking stack (skbs, drivers, and page pool) operate on pages. We have 2 options: 1. Generate struct pages for dmabuf device memory, or, 2. Modify the networking stack to process scatterlist. Approach #1 was attempted in RFC v1. RFC v2 implements approach #2. ** part 3: page pool support We piggy back on page pool memory providers proposal: https://github.com/kuba-moo/linux/tree/pp-providers It allows the page pool to define a memory provider that provides the page allocation and freeing. It helps abstract most of the device memory TCP changes from the driver. ** part 4: support for unreadable skb frags Page pool iovs are not accessible by the host; we implement changes throughput the networking stack to correctly handle skbs with unreadable frags. ** Part 5: recvmsg() APIs We define user APIs for the user to send and receive device memory. Not included with this series is the GVE devmem TCP support, just to simplify the review. Code available here if desired: https://github.com/mina/linux/tree/tcpdevmem This series is built on top of net-next with Jakub's pp-providers changes cherry-picked. * NIC dependencies: 1. (strict) Devmem TCP require the NIC to support header split, i.e. the capability to split incoming packets into a header + payload and to put each into a separate buffer. Devmem TCP works by using device memory for the packet payload, and host memory for the packet headers. 2. (optional) Devmem TCP works better with flow steering support & RSS support, i.e. the NIC's ability to steer flows into certain rx queues. This allows the sysadmin to enable devmem TCP on a subset of the rx queues, and steer devmem TCP traffic onto these queues and non devmem TCP elsewhere. The NIC I have access to with these properties is the GVE with DQO support running in Google Cloud, but any NIC that supports these features would suffice. I may be able to help reviewers bring up devmem TCP on their NICs. * Testing: The series includes a udmabuf kselftest that show a simple use case of devmem TCP and validates the entire data path end to end without a dependency on a specific dmabuf provider. ** Test Setup Kernel: net-next with this series and memory provider API cherry-picked locally. Hardware: Google Cloud A3 VMs. NIC: GVE with header split & RSS & flow steering support.

[PATCH net-next v3] selftests: drv-net: add checksum tests

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Run tools/testing/selftest/net/csum.c as part of drv-net. This binary covers multiple scenarios, based on arguments given, for both IPv4 and IPv6: - Accept UDP correct checksum - Detect UDP invalid checksum - Accept TCP correct checksum - Detect TCP invalid checksum - Transmit UDP: basic checksum offload - Transmit UDP: zero checksum conversion The test direction is reversed between receive and transmit tests, so that the NIC under test is always the local machine. In total this adds up to 12 testcases, with more to follow. For conciseness, I replaced individual functions with a function factory. Also detect hardware offload feature availability using Ethtool netlink and skip tests when either feature is off. This need may be common for offload feature tests and eventually deserving of a thin wrapper in lib.py. Missing are the PF_PACKET based send tests ('-P'). These use virtio_net_hdr to program hardware checksum offload. Which requires looking up the local MAC address and (harder) the MAC of the next hop. I'll have to give it some though how to do that robustly and where that code would belong.

[PATCH v4] selftests/resctrl: fix clang build warnings related to abs(), labs() calls

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) Change to use signed integer data types, in places where subtraction is used (and could end up with negative values). c) Remove a duplicate abs() call in cmt_test.c.

[PATCH] selftests/netfilter: formally SKIP() two cases of setup failure

by John Hubbard

If mnl_socket_open() or mnl_socket_bind() fails, it's generally due to not having the user space parts fully installed and configured correctly. This was previously ignored and reported as a test PASS, but what really happened is that the tests were being skipped. This led to generating inaccurate TAP output (I've omitted the leading '#' character): Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Fix this by using kselftest's SKIP() macro. The new output on the same misconfigured system shows: Totals: pass:0 fail:0 xfail:0 xpass:0 skip:3 error:0 This was briefly discussed already with Felix Huettner [1].

[PATCH AUTOSEL 6.8 18/52] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF

by Sasha Levin

From: Oliver Upton <oliver.upton(a)linux.dev> [ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ] Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid. Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.

[PATCH v2] selftests/resctrl: fix clang build warnings related to abs(), labs() calls

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Furthermore, for this particular resctrl directory, my pending fix [2] must also be applied. Once those fixes are in place, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) Change to use signed integer data types, in places where subtraction is used (and could end up with negative values).

[PATCH net-next v3] selftest: epoll_busy_poll: epoll busy poll tests

by Joe Damato

Add a simple test for the epoll busy poll ioctls, using the kernel selftest harness. This test ensures that the ioctls have the expected return codes and that the kernel properly gets and sets epoll busy poll parameters. The test can be expanded in the future to do real busy polling (provided another machine to act as the client is available). Signed-off-by: Joe Damato <jdamato(a)fastly.com> --- v2 -> v3: - Added this changelog :) - Add libcap to LDLIBS. - Most other changes are in test_set_invalid: - Check if CAP_NET_ADMIN is set in the effective set before setting busy_poll_budget over NAPI_POLL_WEIGHT. The test which follows assumes CAP_NET_ADMIN. - Drop CAP_NET_ADMIN from effective set in order to ensure the ioctl fails when busy_poll_budget exceeds NAPI_POLL_WEIGHT. - Put CAP_NET_ADMIN back into the effective set afterwards. - Changed self->params.busy_poll_budget from 65535 to UINT16_MAX. - Changed the cast for params.busy_poll_usecs from unsigned int to uint32_t in the test_set_invalid case. v1 -> v2: - Rewrote completely to use kernel self test harness. tools/testing/selftests/net/.gitignore | 1 + tools/testing/selftests/net/Makefile | 3 +- tools/testing/selftests/net/epoll_busy_poll.c | 320 ++++++++++++++++++ 3 files changed, 323 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/net/epoll_busy_poll.c diff --git a/tools/testing/selftests/net/.gitignore b/tools/testing/selftests/net/.gitignore index d996a0ab0765..777cfd027076 100644 --- a/tools/testing/selftests/net/.gitignore +++ b/tools/testing/selftests/net/.gitignore @@ -5,6 +5,7 @@ bind_wildcard csum cmsg_sender diag_uid +epoll_busy_poll fin_ack_lat gro hwtstamp_config diff --git a/tools/testing/selftests/net/Makefile b/tools/testing/selftests/net/Makefile index 5befca249452..c6112d08b233 100644 --- a/tools/testing/selftests/net/Makefile +++ b/tools/testing/selftests/net/Makefile @@ -67,7 +67,7 @@ TEST_GEN_FILES += ipsec TEST_GEN_FILES += ioam6_parser TEST_GEN_FILES += gro TEST_GEN_PROGS = reuseport_bpf reuseport_bpf_cpu reuseport_bpf_numa -TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap +TEST_GEN_PROGS += reuseport_dualstack reuseaddr_conflict tls tun tap epoll_busy_poll TEST_GEN_FILES += toeplitz TEST_GEN_FILES += cmsg_sender TEST_GEN_FILES += stress_reuseport_listen @@ -102,6 +102,7 @@ TEST_INCLUDES := forwarding/lib.sh include ../lib.mk +$(OUTPUT)/epoll_busy_poll: LDLIBS += -lcap $(OUTPUT)/reuseport_bpf_numa: LDLIBS += -lnuma $(OUTPUT)/tcp_mmap: LDLIBS += -lpthread -lcrypto $(OUTPUT)/tcp_inq: LDLIBS += -lpthread diff --git a/tools/testing/selftests/net/epoll_busy_poll.c b/tools/testing/selftests/net/epoll_busy_poll.c new file mode 100644 index 000000000000..9dd2830fd67c --- /dev/null +++ b/tools/testing/selftests/net/epoll_busy_poll.c @@ -0,0 +1,320 @@ +// SPDX-License-Identifier: GPL-2.0-or-later + +/* Basic per-epoll context busy poll test. + * + * Only tests the ioctls, but should be expanded to test two connected hosts in + * the future + */ + +#define _GNU_SOURCE + +#include <error.h> +#include <errno.h> +#include <inttypes.h> +#include <limits.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <unistd.h> + +#include <sys/capability.h> + +#include <sys/epoll.h> +#include <sys/ioctl.h> +#include <sys/socket.h> + +#include "../kselftest_harness.h" + +/* if the headers haven't been updated, we need to define some things */ +#if !defined(EPOLL_IOC_TYPE) +struct epoll_params { + uint32_t busy_poll_usecs;

[PATCH bpf-next] bpf, arm64: Add support for lse atomics in bpf_arena

by Puranjay Mohan

When LSE atomics are available, BPF atomic instructions are implemented as single ARM64 atomic instructions, therefore it is easy to enable these in bpf_arena using the currently available exception handling setup. LL_SC atomics use loops and therefore would need more work to enable in bpf_arena. Enable LSE atomics based instructions in bpf_arena and use the bpf_jit_supports_insn() callback to reject atomics in bpf_arena if LSE atomics are not available. All atomics and arena_atomics selftests are passing: [root@ip-172-31-2-216 bpf]# ./test_progs -a atomics,arena_atomics #3/1 arena_atomics/add:OK #3/2 arena_atomics/sub:OK #3/3 arena_atomics/and:OK #3/4 arena_atomics/or:OK #3/5 arena_atomics/xor:OK #3/6 arena_atomics/cmpxchg:OK #3/7 arena_atomics/xchg:OK #3 arena_atomics:OK #10/1 atomics/add:OK #10/2 atomics/sub:OK #10/3 atomics/and:OK #10/4 atomics/or:OK #10/5 atomics/xor:OK #10/6 atomics/cmpxchg:OK #10/7 atomics/xchg:OK #10 atomics:OK Summary: 2/14 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Puranjay Mohan <puranjay(a)kernel.org> --- arch/arm64/net/bpf_jit_comp.c | 48 ++++++++++++++++---- tools/testing/selftests/bpf/DENYLIST.aarch64 | 1 - 2 files changed, 40 insertions(+), 9 deletions(-) diff --git a/arch/arm64/net/bpf_jit_comp.c b/arch/arm64/net/bpf_jit_comp.c index 76b91f36c729..53347d4217f4 100644 --- a/arch/arm64/net/bpf_jit_comp.c +++ b/arch/arm64/net/bpf_jit_comp.c @@ -494,20 +494,26 @@ static int emit_bpf_tail_call(struct jit_ctx *ctx) static int emit_lse_atomic(const struct bpf_insn *insn, struct jit_ctx *ctx) { const u8 code = insn->code; + const u8 arena_vm_base = bpf2a64[ARENA_VM_START]; const u8 dst = bpf2a64[insn->dst_reg]; const u8 src = bpf2a64[insn->src_reg]; const u8 tmp = bpf2a64[TMP_REG_1]; const u8 tmp2 = bpf2a64[TMP_REG_2]; const bool isdw = BPF_SIZE(code) == BPF_DW; + const bool arena = BPF_MODE(code) == BPF_PROBE_ATOMIC; const s16 off = insn->off; - u8 reg; + u8 reg = dst; - if (!off) { - reg = dst; - } else { - emit_a64_mov_i(1, tmp, off, ctx); - emit(A64_ADD(1, tmp, tmp, dst), ctx); - reg = tmp; + if (off || arena) { + if (off) { + emit_a64_mov_i(1, tmp, off, ctx); + emit(A64_ADD(1, tmp, tmp, dst), ctx); + reg = tmp; + } + if (arena) { + emit(A64_ADD(1, tmp, reg, arena_vm_base), ctx); + reg = tmp; + } } switch (insn->imm) { @@ -576,6 +582,12 @@ static int emit_ll_sc_atomic(const struct bpf_insn *insn, struct jit_ctx *ctx) u8 reg; s32 jmp_offset; + if (BPF_MODE(code) == BPF_PROBE_ATOMIC) { + /* ll_sc based atomics don't support unsafe pointers yet. */ + pr_err_once("unknown atomic opcode %02x\n", code); + return -EINVAL; + } + if (!off) { reg = dst; } else { @@ -777,7 +789,8 @@ static int add_exception_handler(const struct bpf_insn *insn, if (BPF_MODE(insn->code) != BPF_PROBE_MEM && BPF_MODE(insn->code) != BPF_PROBE_MEMSX && - BPF_MODE(insn->code) != BPF_PROBE_MEM32) + BPF_MODE(insn->code) != BPF_PROBE_MEM32 && + BPF_MODE(insn->code) != BPF_PROBE_ATOMIC) return 0; if (!ctx->prog->aux->extable || @@ -1474,12 +1487,18 @@ static int build_insn(const struct bpf_insn *insn, struct jit_ctx *ctx, case BPF_STX | BPF_ATOMIC | BPF_W: case BPF_STX | BPF_ATOMIC | BPF_DW: + case BPF_STX | BPF_PROBE_ATOMIC | BPF_W: + case BPF_STX | BPF_PROBE_ATOMIC | BPF_DW: if (cpus_have_cap(ARM64_HAS_LSE_ATOMICS)) ret = emit_lse_atomic(insn, ctx); else ret = emit_ll_sc_atomic(insn, ctx); if (ret) return ret; + + ret = add_exception_handler(insn, ctx, dst); + if (ret) + return ret; break; default: @@ -2527,6 +2546,19 @@ bool bpf_jit_supports_arena(void) return true; } +bool bpf_jit_supports_insn(struct bpf_insn *insn, bool in_arena) +{ + if (!in_arena) + return true; + switch (insn->code) { + case BPF_STX | BPF_ATOMIC | BPF_W: + case BPF_STX | BPF_ATOMIC | BPF_DW: + if (!cpus_have_cap(ARM64_HAS_LSE_ATOMICS)) + return false; + } + return true; +} + void bpf_jit_free(struct bpf_prog *prog) { if (prog->jited) { diff --git a/tools/testing/selftests/bpf/DENYLIST.aarch64 b/tools/testing/selftests/bpf/DENYLIST.aarch64 index cf657fc35619..0445ac38bc07 100644 --- a/tools/testing/selftests/bpf/DENYLIST.aarch64 +++ b/tools/testing/selftests/bpf/DENYLIST.aarch64 @@ -10,4 +10,3 @@ fill_link_info/kprobe_multi_link_info # bpf_program__attach_kprobe_mu fill_link_info/kretprobe_multi_link_info # bpf_program__attach_kprobe_multi_opts unexpected error: -95 fill_link_info/kprobe_multi_invalid_ubuff # bpf_program__attach_kprobe_multi_opts unexpected error: -95 missed/kprobe_recursion # missed_kprobe_recursion__attach unexpected error: -95 (errno 95) -arena_atomics -- 2.40.1

[PATCH v5 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH v2] selftests/net: fix uninitialized variables

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about three variables that are not initialized in all cases: 1) The opt_ipproto_off variable is used uninitialized if "testname" is not "ip". Willem de Bruijn pointed out that this is an actual bug, and suggested the fix that I'm using here (thanks!). 2) The addr_len is used uninitialized, but only in the assert case, which bails out, so this is harmless. 3) The family variable in add_listener() is only used uninitialized in the error case (neither IPv4 nor IPv6 is specified), so it's also harmless. Fix by initializing each variable.

[PATCH AUTOSEL 6.6 15/43] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF

by Sasha Levin

From: Oliver Upton <oliver.upton(a)linux.dev> [ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ] Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid. Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.

[BUG selftests/pidfd] pidfd_setns_test HANG

by Mirsad Todorovac

Hi, all, With the latest 6.9-rc7 torvalds tree kernel, the "make kselftest" always hangs in the following ./pidfd_setns_test. Symptoms are that all ./pidfd_netne_test processes end up in pause() syscalls, with nothing to wake them up. Please find the config attached. All the options from the selftests/pidfdconfig are on (verified): CONFIG_UTS_NS=y CONFIG_IPC_NS=y CONFIG_USER_NS=y CONFIG_PID_NS=y CONFIG_NET_NS=y CONFIG_CGROUPS=y CONFIG_CHECKPOINT_RESTORE=y root 2090101 5211 0 21:53 pts/1 00:00:00 make OUTPUT=/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/pidfd -C pidfd run_tests SRC_PATH=/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests OB root 2090102 2090101 0 21:53 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133026 2090102 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133027 2133026 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133028 2133027 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133031 2133028 0 21:54 pts/1 00:00:00 /bin/sh -c BASE_DIR="/home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests"; . /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/runner.sh; if root 2133033 2133031 0 21:54 pts/1 00:00:00 perl /home/marvin/linux/kernel/linux_torvalds/tools/testing/selftests/kselftest/prefix.pl root 2133050 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133051 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133056 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133057 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133062 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133063 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133068 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test root 2133069 2887 0 21:54 pts/1 00:00:00 ./pidfd_setns_test . . . marvin@defiant:~/linux/kernel/linux_torvalds$ sudo bash [sudo] password for marvin: root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133050 strace: Process 2133050 attached pause(^Cstrace: Process 2133050 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133051 strace: Process 2133051 attached pause(^Cstrace: Process 2133051 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133056 strace: Process 2133056 attached pause(^Cstrace: Process 2133056 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133057 strace: Process 2133057 attached pause(^Cstrace: Process 2133057 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133062 strace: Process 2133062 attached pause(^Cstrace: Process 2133062 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133063 strace: Process 2133063 attached pause(^Cstrace: Process 2133063 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# root@defiant:/home/marvin/linux/kernel/linux_torvalds# root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133068 strace: Process 2133068 attached pause(^Cstrace: Process 2133068 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# strace -p 2133069 strace: Process 2133069 attached pause(^Cstrace: Process 2133069 detached <detached ...> root@defiant:/home/marvin/linux/kernel/linux_torvalds# The output log is: #

[PATCH net-next v8 0/3] net: gro: remove network_header use, move p->{flush/flush_id} calculations to L4

by Richard Gobert

The cb fields network_offset and inner_network_offset are used instead of skb->network_header throughout GRO. These fields are then leveraged in the next commit to remove flush_id state from napi_gro_cb, and stateful code in {ipv6,inet}_gro_receive which may be unnecessarily complicated due to encapsulation support in GRO. These fields are checked in L4 instead. 3rd patch adds tests for different flush_id flows in GRO. v7 -> v8: - Remove network_header use in gro - Re-send commits after the dependent patch to net was applied - v7: https://lore.kernel.org/all/20240412155533.115507-1-richardbgobert@gmail.co… v6 -> v7: - Moved bug fixes to a separate submission in net - Added UDP fwd benchmark - v6: https://lore.kernel.org/all/20240410153423.107381-1-richardbgobert@gmail.co… v5 -> v6: - Write inner_network_offset in vxlan and geneve - Ignore is_atomic when DF=0 - v5: https://lore.kernel.org/all/20240408141720.98832-1-richardbgobert@gmail.com/ v4 -> v5: - Add 1st commit - flush id checks in udp_gro_receive segment which can be backported by itself - Add TCP measurements for the 5th commit - Add flush id tests to ensure flush id logic is preserved in GRO - Simplify gro_inet_flush by removing a branch - v4: https://lore.kernel.org/all/202420325182543.87683-1-richardbgobert@gmail.co… v3 -> v4: - Fix code comment and commit message typos - v3: https://lore.kernel.org/all/f939c84a-2322-4393-a5b0-9b1e0be8ed8e@gmail.com/ v2 -> v3: - Use napi_gro_cb instead of skb->{offset} - v2: https://lore.kernel.org/all/2ce1600b-e733-448b-91ac-9d0ae2b866a4@gmail.com/ v1 -> v2: - Pass p_off in *_gro_complete to fix UDP bug - Remove more conditionals and memory fetches from inet_gro_flush - v1: https://lore.kernel.org/netdev/e1d22505-c5f8-4c02-a997-64248480338b@gmail.c… Richard Gobert (3): net: gro: use cb instead of skb->network_header net: gro: move L3 flush checks to tcp_gro_receive and udp_gro_receive_segment selftests/net: add flush id selftests include/net/gro.h | 75 +++++++++++++-- net/core/gro.c | 3 - net/ipv4/af_inet.c | 45 +-------- net/ipv4/tcp_offload.c | 18 +--- net/ipv4/udp_offload.c | 10 +- net/ipv6/ip6_offload.c | 16 +--- net/ipv6/tcpv6_offload.c | 3 +- tools/testing/selftests/net/gro.c | 147 ++++++++++++++++++++++++++++++ 8 files changed, 225 insertions(+), 92 deletions(-) -- 2.36.1

[PATCH v6 00/10] Fix Kselftest's vfork() side effects

by Mickaël Salaün

Hi, This sixth series just update the last patch description. Shuah, I think this should be in -next really soon to make sure everything works fine for the v6.9 release, which is not currently the case. I cannot test against all kselftests though. I would prefer to let you handle this, but I guess you're not able to do so and I'll push it on my branch without reply from you. Even if I push it on my branch, please push it on yours too as soon as you see this and I'll remove it from mine. Mark, Jakub, could you please test this series? As reported by Kernel Test Robot [1] and Sean Christopherson [2], some tests fail since v6.9-rc1 . This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This series fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust. I tried different approaches and I found this one to be the cleaner and less invasive for current test cases. I successfully ran the following tests (using TEST_F and fork/clone/clone3, and KVM_ONE_VCPU_TEST) with this series: - kvm:fix_hypercall_test - kvm:sync_regs_test - kvm:userspace_msr_exit_test - kvm:vmx_pmu_caps_test - landlock:fs_test - landlock:net_test - landlock:ptrace_test - move_mount_set_group:move_mount_set_group_test - net/af_unix:scm_pidfd - perf_events:remove_on_exec - pidfd:pidfd_getfd_test - pidfd:pidfd_setns_test - seccomp:seccomp_bpf - user_events:abi_test [1] https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com [2] https://lore.kernel.org/r/ZjPelW6-AbtYvslu@google.com Previous versions: v1: https://lore.kernel.org/r/20240426172252.1862930-1-mic@digikod.net v2: https://lore.kernel.org/r/20240429130931.2394118-1-mic@digikod.net v3: https://lore.kernel.org/r/20240429191911.2552580-1-mic@digikod.net v4: https://lore.kernel.org/r/20240502210926.145539-1-mic@digikod.net v5: https://lore.kernel.org/r/20240503105820.300927-1-mic@digikod.net Regards, Mickaël Salaün (10): selftests/pidfd: Fix config for pidfd_setns_test selftests/landlock: Fix FS tests when run on a private mount point selftests/harness: Fix fixture teardown selftests/harness: Fix interleaved scheduling leading to race conditions selftests/landlock: Do not allocate memory in fixture data selftests/harness: Constify fixture variants selftests/pidfd: Fix wrong expectation selftests/harness: Share _metadata between forked processes selftests/harness: Fix vfork() side effects selftests/harness: Handle TEST_F()'s explicit exit codes tools/testing/selftests/kselftest_harness.h | 122 +++++++++++++----- tools/testing/selftests/landlock/fs_test.c | 83 +++++++----- tools/testing/selftests/pidfd/config | 2 + .../selftests/pidfd/pidfd_setns_test.c | 2 +- 4 files changed, 143 insertions(+), 66 deletions(-) base-commit: e67572cd2204894179d89bd7b984072f19313b03 -- 2.45.0

[PATCH 00/18] HID: Include current HID-BPF fixes in tree

by Benjamin Tissoires

When I introduced HID-BPF, I mentioned that we should ship the HID-BPF programs in the kernel when they are fixes so that everybody can benefit from them. I tried multiple times to do so but I was confronted to a tough problem: how can I make the kernel load them automatically? I went over a few solutions, but it always came down to something either ugly, or either not satisfying (like forcing `bpftool` to be compiled first, or not being able to insert them as a module). OTOH, I was working with Peter on `udev-hid-bpf`[0] as a proof of concept on how a minimal loader should look like. This allowed me to experiment on the BPF files and how they should look like. And after further thoughts, I realized that `udev-hid-bpf` could very well be the `kmod load` that we currently have: - the kernel handles the device normally - a udev event is emitted - a udev rule fires `udev-hid-bpf` and load the appropriate HID-BPF file(s) based on the modalias Given that most HID devices are supposed to work to a minimal level when connected without any driver, this makes the whole HID-BPF programs nice to have but not critical. We can then postpone the HID-BPF loading when userspace is ready. Working with HID-BPF is also a much better user experience for end users (as I predicted). All they have to do is to go to the `udev-hid-bpf` project, fetch an artifact from the MR that concerns them, run `install.sh` (no compilation required), and their devices are fixed (minus some back and forth when the HID-BPF program needs some changes). So I already have that loader available, and it works well enough for our users. But the missing point was still how to "upstream" those BPF fixes? That's where this patch series comes in: we simply store the fixes in the kernel under `drivers/hid/bpf/progs`, provide a way to compile them, but also add tests for them in the selftests dir. Once a program is accepted here, for convenience, the same program will move from a "testing" directory to a "stable" directory on `udev-hid-bpf`. This way, distributions don't need to follow when there is a new program added here, they can just ship the "stable" ones from `udev-hid-bpf`.

[PATCH net-next v3 0/2] fix icmp error source address over xfrm tunnel

by Antony Antony

Hi, This fix, originally intended for XFRM/IPsec, has been recommended by Steffen Klassert to submit to the net tree. The patch addresses a minor issue related to the IPv4 source address of ICMP error messages, which originated from an old 2011 commit: 415b3334a21a ("icmp: Fix regression in nexthop resolution during replies.") The omission of a "Fixes" tag in the following commit is deliberate to prevent potential test failures and subsequent regression issues that may arise from backporting this patch all stable kerenels. This is a minor fix, anot not security fix. With a seleftest I am submitting this to net-next tree. v2->v3 : fix testscript. The IFS, space, got mangled. v1->v2 : add kernel selftest script Antony Antony (2): xfrm: fix source address in icmp error generation from IPsec gateway selftests/net: add ICMP unreachable over IPsec tunnel net/ipv4/icmp.c | 1 - tools/testing/selftests/net/Makefile | 1 + tools/testing/selftests/net/xfrm_state.sh | 624 ++++++++++++++++++++++ 3 files changed, 625 insertions(+), 1 deletion(-) create mode 100755 tools/testing/selftests/net/xfrm_state.sh -- 2.30.2

[PATCH net] selftests/bpf: fix pointer arithmetic in test_xdp_do_redirect

by Michal Schmidt

Cast operation has a higher precedence than addition. The code here wants to zero the 2nd half of the 64-bit metadata, but due to a pointer arithmetic mistake, it writes the zero at offset 16 instead. Just adding parentheses around "data + 4" would fix this, but I think this will be slightly better readable with array syntax. I was unable to test this with tools/testing/selftests/bpf/vmtest.sh, because my glibc is newer than glibc in the provided VM image. So I just checked the difference in the compiled code. objdump -S tools/testing/selftests/bpf/xdp_do_redirect.test.o: - *((__u32 *)data) = 0x42; /* metadata test value */ + ((__u32 *)data)[0] = 0x42; /* metadata test value */ be7: 48 8d 85 30 fc ff ff lea -0x3d0(%rbp),%rax bee: c7 00 42 00 00 00 movl $0x42,(%rax) - *((__u32 *)data + 4) = 0; + ((__u32 *)data)[1] = 0; bf4: 48 8d 85 30 fc ff ff lea -0x3d0(%rbp),%rax - bfb: 48 83 c0 10 add $0x10,%rax + bfb: 48 83 c0 04 add $0x4,%rax bff: c7 00 00 00 00 00 movl $0x0,(%rax) Fixes: 5640b6d89434 ("selftests/bpf: fix "metadata marker" getting overwritten by the netstack") Signed-off-by: Michal Schmidt <mschmidt(a)redhat.com> --- tools/testing/selftests/bpf/prog_tests/xdp_do_redirect.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/bpf/prog_tests/xdp_do_redirect.c b/tools/testing/selftests/bpf/prog_tests/xdp_do_redirect.c index 498d3bdaa4b0..bad0ea167be7 100644 --- a/tools/testing/selftests/bpf/prog_tests/xdp_do_redirect.c +++ b/tools/testing/selftests/bpf/prog_tests/xdp_do_redirect.c @@ -107,8 +107,8 @@ void test_xdp_do_redirect(void) .attach_point = BPF_TC_INGRESS); memcpy(&data[sizeof(__u64)], &pkt_udp, sizeof(pkt_udp)); - *((__u32 *)data) = 0x42; /* metadata test value */ - *((__u32 *)data + 4) = 0; + ((__u32 *)data)[0] = 0x42; /* metadata test value */ + ((__u32 *)data)[1] = 0; skel = test_xdp_do_redirect__open(); if (!ASSERT_OK_PTR(skel, "skel")) -- 2.44.0

[PATCH v2] selftests: exec: make binaries position independent

by Muhammad Usama Anjum

The -static overrides the -pie and binaries aren't position independent anymore. Use -static-pie instead which would produce a static and position independent binary. This has been caught by clang's warnings: clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument] Tested with both gcc and clang after this change.

[PATCH v2] bpftool, selftests/hid/bpf: fix 29 clang warnings

When building either tools/bpf/bpftool, or tools/testing/selftests/hid, (the same Makefile is used for these), clang generates many instances of the following: "clang: warning: -lLLVM-17: 'linker' input unused" Quentin points out that the LLVM version is only required in $(LIBS), not in $(CFLAGS), so the fix is to remove it from CFLAGS.

[PATCH] selftests/exec: build with -fPIE instead of -pie, to make clang happy

by John Hubbard

clang doesn't deal well with "-pie -static": it warns that -pie is an unused option here. Changing to "-fPIE -static" solves this problem for clang, while keeping the gcc results identical. The problem is visible when building via: make LLVM=1 -C tools/testing/selftests Again: gcc 13 produces identical binaries for all of these programs, both before and after this commit (using "-pie"), and after (using "-fPIE"). Also, the runtime results are the same for both clang and gcc builds.

[PATCH 1/2] selftests/net: suppress clang's "variable-sized type not at the end" warning

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns that "a variable sized type not at the end of a struct or class is a GNU extension". These cases are not easily changed, because they involve structs that are part of the API. Fortunately, however, the tests seem to be doing just fine (specifically, neither affected test runs any differently with gcc vs. clang builds, on my test system) regardless of the warning. So, all the warning is doing is preventing a clean build of selftests/net. Fix this by suppressing this particular clang warning for the selftests/net suite.

[PATCH v2] selftests/netfilter: return a value for several "int" functions

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...clang warns, correctly, that several functions declared with an "int" return type are not always returning values in all cases (or at least, clang cannot prove that they always return a value). Fix this by returning an appropriate value for each function. Thanks to Felix Huettner for recommending MNL_CB_OK (which is non-zero) for the return value of the count_entries() callback.

[PATCH] selftests/resctrl: fix clang build warnings related to abs(), labs() calls

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Furthermore, for this particular resctrl directory, my pending fix [2] must also be applied. Once those fixes are in place, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) don't call labs() unnecessarily.

[PATCH v5 00/10] Fix Kselftest's vfork() side effects

by Mickaël Salaün

Hi, This fifth series fixes _metadata reset and fixes the last patch to handle code set with direct calls to _exit(). As reported by Kernel Test Robot [1], some pidfd tests fail. This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This series fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust. I tried different approaches and I found this one to be the cleaner and less invasive for current test cases. I successfully ran the following tests (using TEST_F and fork/clone/clone3, and KVM_ONE_VCPU_TEST) with this series: - kvm:fix_hypercall_test - kvm:sync_regs_test - kvm:userspace_msr_exit_test - kvm:vmx_pmu_caps_test - landlock:fs_test - landlock:net_test - landlock:ptrace_test - move_mount_set_group:move_mount_set_group_test - net/af_unix:scm_pidfd - perf_events:remove_on_exec - pidfd:pidfd_getfd_test - pidfd:pidfd_setns_test - seccomp:seccomp_bpf - user_events:abi_test [1] https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Previous versions: v1: https://lore.kernel.org/r/20240426172252.1862930-1-mic@digikod.net v2: https://lore.kernel.org/r/20240429130931.2394118-1-mic@digikod.net v3: https://lore.kernel.org/r/20240429191911.2552580-1-mic@digikod.net v4: https://lore.kernel.org/r/20240502210926.145539-1-mic@digikod.net Regards, Mickaël Salaün (10): selftests/pidfd: Fix config for pidfd_setns_test selftests/landlock: Fix FS tests when run on a private mount point selftests/harness: Fix fixture teardown selftests/harness: Fix interleaved scheduling leading to race conditions selftests/landlock: Do not allocate memory in fixture data selftests/harness: Constify fixture variants selftests/pidfd: Fix wrong expectation selftests/harness: Share _metadata between forked processes selftests/harness: Fix vfork() side effects selftests/harness: Handle TEST_F()'s explicit exit codes tools/testing/selftests/kselftest_harness.h | 122 +++++++++++++----- tools/testing/selftests/landlock/fs_test.c | 83 +++++++----- tools/testing/selftests/pidfd/config | 2 + .../selftests/pidfd/pidfd_setns_test.c | 2 +- 4 files changed, 143 insertions(+), 66 deletions(-) base-commit: e67572cd2204894179d89bd7b984072f19313b03 -- 2.45.0

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about "taking address of packed member 'write_index' ". This is not particularly helpful, because the test code really wants to write to exactly this location, and if it ends up being unaligned, then the test won't work (and may segfault, depending on the CPU type). If that ever comes up, it will be obvious and can be fixed. But all it's doing now is prevent a clean clang build, so disable the warning.

[PATCH net-next v2 0/2] Fix icmp error source address over xfrm tunnel

by Antony Antony

Hi, This fix, originally intended for XFRM/IPsec, has been recommended by Steffen Klassert to submit to the net tree. The patch addresses a minor issue related to the IPv4 source address of ICMP error messages, which originated from an old 2011 commit: 415b3334a21a ("icmp: Fix regression in nexthop resolution during replies.") The omission of a "Fixes" tag in the following commit is deliberate to prevent potential test failures and subsequent regression issues that may arise from backporting this patch all stable kerenels. This is a minor fix, anot not security fix. With a seleftest I am submitting this to net-next tree. v1->v2 : add kernel selftest script Antony Antony (2): xfrm: fix source address in icmp error generation from IPsec gateway selftests: add ICMP unreachable over IPsec tunnel net/ipv4/icmp.c | 1 - tools/testing/selftests/net/Makefile | 1 + tools/testing/selftests/net/xfrm_state.sh | 624 ++++++++++++++++++++++ 3 files changed, 625 insertions(+), 1 deletion(-) create mode 100755 tools/testing/selftests/net/xfrm_state.sh -- 2.30.2

[PATCH] kunit: Cover 'assert.c' with tests

by Ivan Orlov

There are multiple assertion formatting functions in the `assert.c` file, which are not covered with tests yet. Implement the KUnit test for these functions. The test consists of 11 test cases for the following functions: 1) 'is_literal' 2) 'is_str_literal' 3) 'kunit_assert_prologue', test case for multiple assert types 4) 'kunit_assert_print_msg' 5) 'kunit_unary_assert_format' 6) 'kunit_ptr_not_err_assert_format' 7) 'kunit_binary_assert_format' 8) 'kunit_binary_ptr_assert_format' 9) 'kunit_binary_str_assert_format' 10) 'kunit_assert_hexdump' 11) 'kunit_mem_assert_format' The test aims at maximizing the branch coverage for the assertion formatting functions. As you can see, it covers some of the static helper functions as well, so we have to import the test source in the `assert.c` file in order to be able to call and validate them.

[PATCH net-next] selftest: epoll_busy_poll: epoll busy poll tests

by Joe Damato

Add a simple test for the epoll busy poll ioctls. This test ensures that the ioctls have the expected return codes and that the kernel properly gets and sets epoll busy poll parameters. The test can be expanded in the future to do real busy polling (provided another machine to act as the client is available). To run the test (use -s for "simple" test): ./epoll_busy_poll -s On success, nothing is written to stdout/stderr and the exit code is 0.

[PATCH net-next v2] selftests: drv-net: add checksum tests

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Run tools/testing/selftest/net/csum.c as part of drv-net. This binary covers multiple scenarios, based on arguments given, for both IPv4 and IPv6: - Accept UDP correct checksum - Detect UDP invalid checksum - Accept TCP correct checksum - Detect TCP invalid checksum - Transmit UDP: basic checksum offload - Transmit UDP: zero checksum conversion The test direction is reversed between receive and transmit tests, so that the NIC under test is always the local machine. In total this adds up to 12 testcases, with more to follow. For conciseness, I replaced individual functions with a function factory. Also detect hardware offload feature availability using Ethtool netlink and skip tests when either feature is off. This need may be common for offload feature tests and eventually deserving of a thin wrapper in lib.py. Missing are the PF_PACKET based send tests ('-P'). These use virtio_net_hdr to program hardware checksum offload. Which requires looking up the local MAC address and (harder) the MAC of the next hop. I'll have to give it some though how to do that robustly and where that code would belong.

[PATCH v3] selftest/tty: Use harness framework in tty

by Shengyu Li

Use kselftest_harness.h to simplify the code structure by eliminating conditional logic. Enhance diagnostics by directly printing relevant info, such as access and modification times, upon test failure. Reflecting common I/O optimizations, the access time usually remains unchanged, while the modify time is expected to update. Accordingly, these elements have been logically separated.

[PATCH V5] KVM: selftests: Add a new option to rseq_test

by Zide Chen

Currently, the migration worker delays 1-10 us, assuming that one KVM_RUN iteration only takes a few microseconds. But if the CPU low power wakeup latency is large enough, for example, hundreds or even thousands of microseconds deep C-state exit latencies on x86 server CPUs, it may happen that it's not able to wakeup the target CPU before the migration worker starts to migrate the vCPU thread to the next CPU. If the system workload is light, most CPUs could be at a certain low power state, which may result in less successful migrations and fail the migration/KVM_RUN ratio sanity check. But this is not supposed to be deemed a test failure. This patch adds a command line option to skip the sanity check in this case.

[PATCH] selftests: default to host arch for LLVM builds

by Valentin Obst

Align the behavior for gcc and clang builds by interpreting unset `ARCH` and `CROSS_COMPILE` variables in `LLVM` builds as a sign that the user wants to build for the host architecture. This patch preserves the properties that setting the `ARCH` variable to an unknown value will trigger an error that complains about insufficient information, and that a set `CROSS_COMPILE` variable will override the target triple that is determined based on presence/absence of `ARCH`. When compiling with clang, i.e., `LLVM` is set, an unset `ARCH` variable in combination with an unset `CROSS_COMPILE` variable, i.e., compiling for the host architecture, leads to compilation failures since `lib.mk` can not determine the clang target triple. In this case, the following error message is displayed for each subsystem that does not set `ARCH` in its own Makefile before including `lib.mk` (lines wrapped at 75 chrs): make[1]: Entering directory '/mnt/build/linux/tools/testing/selftests/ sysctl' ../lib.mk:33: *** Specify CROSS_COMPILE or add '--target=' option to lib.mk. Stop. make[1]: Leaving directory '/mnt/build/linux/tools/testing/selftests/ sysctl' In the same scenario a gcc build would default to the host architecture, i.e., it would use plain `gcc`. Fixes: 795285ef2425 ("selftests: Fix clang cross compilation") Reviewed-by: Mark Brown <broonie(a)kernel.org> Signed-off-by: Valentin Obst <kernel(a)valentinobst.de> --- I am not entirely sure whether this behavior is in fact known and intended and whether the way to obtain the host target triple is sufficiently general. The flag was introduced in llvm-8 with [1], it will be an error in older clang versions. The target triple you get with `-print-target-triple` may not be the same that you would get when explicitly setting ARCH to you host architecture. For example on my x86_64 system it get `x86_64-pc-linux-gnu` instead of `x86_64-linux-gnu`, similar deviations were observed when testing other clang binaries on compiler-explorer, e.g., [2]. An alternative could be to simply do: ARCH ?= $(shell uname -m) before using it to select the target. Possibly with some post processing, but at that point we would likely be replicating `scripts/subarch.include`. This is what some subsystem Makefiles do before including `lib.mk`. This change might make it possible to remove the explicit setting of `ARCH` from the few subsystem Makefiles that do it.

[PATCH] selftests/binderfs: use the Makefile's rules, not Make's implicit rules

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...the following error occurs: clang: error: cannot specify -o when generating multiple output files This is because clang, unlike gcc, won't accept invocations of this form: clang file1.c header2.h While trying to fix this, I noticed that: a) selftests/lib.mk already avoids the problem, and b) The binderfs Makefile indavertently bypasses the selftests/lib.mk build system, and quitely uses Make's implicit build rules for .c files instead. The Makefile attempts to set up both a dependency and a source file, neither of which was needed, because lib.mk is able to automatically handle both. This line: binderfs_test: binderfs_test.c ...causes Make's implicit rules to run, which builds binderfs_test without ever looking at lib.mk. Fix this by simply deleting the "binderfs_test:" Makefile target and letting lib.mk handle it instead.

[PATCH v5 00/17] riscv: Support vendor extensions and xtheadvector

by Charlie Jenkins

This patch series ended up much larger than expected, please bear with me! The goal here is to support vendor extensions, starting at probing the device tree and ending with reporting to userspace. The main design objective was to allow vendors to operate independently of each other. This has been achieved by delegating vendor extensions to a their own files and then accumulating the extensions in arch/riscv/kernel/vendor_extensions.c. Each vendor will have their own list of extensions they support. There is a new hwprobe key RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0 that is used to request which thead vendor extensions are supported on the current platform. This allows future vendors to allocate hwprobe keys for their vendor. On to the xtheadvector specific code. xtheadvector is a custom extension that is based upon riscv vector version 0.7.1 [1]. All of the vector routines have been modified to support this alternative vector version based upon whether xtheadvector was determined to be supported at boot. I have tested this with an Allwinner Nezha board. I ran into issues booting the board on 6.9-rc1 so I applied these patches to 6.8. There are a couple of minor merge conflicts that do arrise when doing that, so please let me know if you have been able to boot this board with a 6.9 kernel. I used SkiffOS [2] to manage building the image, but upgraded the U-Boot version to Samuel Holland's more up-to-date version [3] and changed out the device tree used by U-Boot with the device trees that are present in upstream linux and this series. Thank you Samuel for all of the work you did to make this task possible. To test the integration, I used the riscv vector kselftests. I modified the test cases to be able to more easily extend them, and then added a xtheadvector target that works by calling hwprobe and swapping out the vector asm if needed.

[PATCH] selftest/timerns: fix clang build failures for abs() calls

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...then clang warns about mismatches between the expected and required integer length being supplied to abs(3). Fix this by using the correct variant of abs(3): labs(3) or llabs(3), in these cases.

In order support old version kernel testing, is it possible to use rtc procfs to validate wakealarm function for old version kernel ? Can I move this rtc alarm validation to <linux_root>/tools/testing/selftests/rtc/rtctest.c ? So, we could try to use RTC_PARAM_GET ioctl first and then roll back to use rtc procfs if new RTC_PARAM_GET ioctl was not supported.

[PATCH v4 00/10] Fix Kselftest's vfork() side effects

by Mickaël Salaün

Hi, As reported by Kernel Test Robot [1], some pidfd tests fail. This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This series fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust. I tried different approaches and I found this one to be the cleaner and less invasive for current test cases. This fourth series add a patch from Sean Christopherson that fixes KVM tests. I successfully ran the following tests (using TEST_F and fork/clone/clone3) with this series: - landlock:fs_test - landlock:net_test - landlock:ptrace_test - move_mount_set_group:move_mount_set_group_test - net/af_unix:scm_pidfd - perf_events:remove_on_exec - pidfd:pidfd_getfd_test - pidfd:pidfd_setns_test - seccomp:seccomp_bpf - user_events:abi_test [1] https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Previous versions: v1: https://lore.kernel.org/r/20240426172252.1862930-1-mic@digikod.net v2: https://lore.kernel.org/r/20240429130931.2394118-1-mic@digikod.net v3: https://lore.kernel.org/r/20240429191911.2552580-1-mic@digikod.net Regards, Mickaël Salaün (10): selftests/pidfd: Fix config for pidfd_setns_test selftests/landlock: Fix FS tests when run on a private mount point selftests/harness: Fix fixture teardown selftests/harness: Fix interleaved scheduling leading to race conditions selftests/landlock: Do not allocate memory in fixture data selftests/harness: Constify fixture variants selftests/pidfd: Fix wrong expectation selftests/harness: Share _metadata between forked processes selftests/harness: Fix vfork() side effects selftests/harness: Fix TEST_F()'s exit codes tools/testing/selftests/kselftest_harness.h | 123 +++++++++++++----- tools/testing/selftests/landlock/fs_test.c | 83 +++++++----- tools/testing/selftests/pidfd/config | 2 + .../selftests/pidfd/pidfd_setns_test.c | 2 +- 4 files changed, 141 insertions(+), 69 deletions(-) base-commit: e67572cd2204894179d89bd7b984072f19313b03 -- 2.45.0

[PATCH] selftests/vDSO: fix clang build errors and warnings

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...there are several warnings, and an error. This fixes all of those and allows these tests to run and pass. 1. Fix linker error (undefined reference to memcpy) by providing a local version of memcpy. 2. clang complains about using this form: if (g = h & 0xf0000000) ...so factor out the assignment into a separate step. 3. The code is passing a signed const char* to elf_hash(), which expects a const unsigned char *. There are several callers, so fix this at the source by allowing the function to accept a signed argument, and then converting to unsigned operations, once inside the function. 4. clang doesn't have __attribute__((externally_visible)) and generates a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem to require that attribute in order to build, run and pass tests here, so remove it.

[PATCH net-next] selftests/net: skip partial checksum packets in csum test

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Detect packets with ip_summed CHECKSUM_PARTIAL and skip these. These should not exist, as the test sends individual packets between two hosts. But if (HW) GRO is on, with randomized content sometimes subsequent packets can be coalesced. In this case the GSO packet checksum is converted to a pseudo checksum in anticipation of sending out as TSO/USO. So the field will not match the expected value. Do not count these as test errors.

[PATCH v4 00/16] riscv: Support vendor extensions and xtheadvector

by Charlie Jenkins

This patch series ended up much larger than expected, please bear with me! The goal here is to support vendor extensions, starting at probing the device tree and ending with reporting to userspace. The main design objective was to allow vendors to operate independently of each other. This has been achieved by delegating vendor extensions to a their own files and then accumulating the extensions in arch/riscv/kernel/vendor_extensions.c. Each vendor will have their own list of extensions they support. There is a new hwprobe key RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0 that is used to request which thead vendor extensions are supported on the current platform. This allows future vendors to allocate hwprobe keys for their vendor. On to the xtheadvector specific code. xtheadvector is a custom extension that is based upon riscv vector version 0.7.1 [1]. All of the vector routines have been modified to support this alternative vector version based upon whether xtheadvector was determined to be supported at boot. I have tested this with an Allwinner Nezha board. I ran into issues booting the board on 6.9-rc1 so I applied these patches to 6.8. There are a couple of minor merge conflicts that do arrise when doing that, so please let me know if you have been able to boot this board with a 6.9 kernel. I used SkiffOS [2] to manage building the image, but upgraded the U-Boot version to Samuel Holland's more up-to-date version [3] and changed out the device tree used by U-Boot with the device trees that are present in upstream linux and this series. Thank you Samuel for all of the work you did to make this task possible. To test the integration, I used the riscv vector kselftests. I modified the test cases to be able to more easily extend them, and then added a xtheadvector target that works by calling hwprobe and swapping out the vector asm if needed.

[PATCH v3 bpf-next 0/6] selftests/bpf: Add sockaddr tests for kernel networking

by Jordan Rife

This patch series adds test coverage for BPF sockaddr hooks and their interactions with kernel socket functions (i.e. kernel_bind(), kernel_connect(), kernel_sendmsg(), sock_sendmsg(), kernel_getpeername(), and kernel_getsockname()) while also rounding out IPv4 and IPv6 sockaddr hook coverage in prog_tests/sock_addr.c. As with v1 of this patch series, we add regression coverage for the issues addressed by these patches, - commit 0bdf399342c5("net: Avoid address overwrite in kernel_connect") - commit 86a7e0b69bd5("net: prevent rewrite of msg_name in sock_sendmsg()") - commit c889a99a21bf("net: prevent address rewrite in kernel_bind()") - commit 01b2885d9415("net: Save and restore msg_namelen in sock_sendmsg") but broaden the focus a bit. In order to extend prog_tests/sock_addr.c to test these kernel functions, we add a set of new kfuncs that wrap individual socket operations to bpf_testmod and invoke them through set of corresponding SYSCALL programs (progs/sock_addr_kern.c). Each test case can be configured to use a different set of "sock_ops" depending on whether it is testing kernel calls (kernel_bind(), kernel_connect(), etc.) or system calls (bind(), connect(), etc.). ======= Patches ======= * Patch 1 fixes the sock_addr bind test program to work for big endian architectures such as s390x. * Patch 2 introduces the new kfuncs to bpf_testmod. * Patch 3 introduces the BPF program which allows us to invoke these kfuncs invividually from the test program. * Patch 4 lays the groundwork for IPv4 and IPv6 sockaddr hook coverage by migrating much of the environment setup logic from bpf/test_sock_addr.sh into prog_tests/sock_addr.c and moves test cases to cover bind4/6, connect4/6, sendmsg4/6 and recvmsg4/6 hooks. * Patch 5 makes the set of socket operations for each test case configurable, laying the groundwork for Patch 6. * Patch 6 introduces two sets of sock_ops that invoke the kernel equivalents of connect(), bind(), etc. and uses these to add coverage for the kernel socket functions. ======= Changes ======= v2->v3 ------ * Renamed bind helpers. Dropped "_ntoh" suffix. * Added guards to kfuncs to make sure addrlen and msglen do not exceed the buffer capacity. * Added KF_SLEEPABLE flag to kfuncs. * Added a mutex (sock_lock) to kfuncs to serialize access to sock. * Added NULL check for sock to each kfunc. * Use the "sock_addr" networking namespace for all network interface setup and testing. * Use "nodad" when calling "ip -6 addr add" during interface setup to avoid delays and remove ping loop. * Removed test cases from test_sock_addr.c to make it clear what remains to be migrated. * Removed unused parameter (expect_change) from sock_addr_op(). Link: https://lore.kernel.org/bpf/20240412165230.2009746-1-jrife@google.com/T/#u v1->v2 ------ * Dropped test_progs/sock_addr_kern.c and the sock_addr_kern test module in favor of simply expanding bpf_testmod and test_progs/sock_addr.c. * Migrated environment setup logic from bpf/test_sock_addr.sh into prog_tests/sock_addr.c rather than invoking the script from the test program. * Added kfuncs to bpf_testmod as well as the sock_addr_kern BPF program to enable us to invoke kernel socket functions from test_progs/sock_addr.c. * Added test coverage for kernel socket functions to test_progs/sock_addr.c.

[PATCH V4] KVM: selftests: Add a new option to rseq_test

by Zide Chen

Currently, the migration worker delays 1-10 us, assuming that one KVM_RUN iteration only takes a few microseconds. But if the CPU low power wakeup latency is large enough, for example, hundreds or even thousands of microseconds deep C-state exit latencies on x86 server CPUs, it may happen that it's not able to wakeup the target CPU before the migration worker starts to migrate the vCPU thread to the next CPU. If the system workload is light, most CPUs could be at a certain low power state, which may result in less successful migrations and fail the migration/KVM_RUN ratio sanity check. But this is not supposed to be deemed a test failure. This patch adds a command line option to skip the sanity check in this case.

[PATCH v4 00/12] 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. XFAIL which would be a great match here cannot be used. Remove the no_print handling and use vfork() to run the test in a different process than the setup. This way we don't need to pass "failing step" via the exit code. Further clean up the exit codes so that we can use all KSFT_* values. Rewrite the result printing to make handling XFAIL/XPASS easier. Support tests declaring combinations of fixture + variant they expect to fail. Merge plan is to put it on top of -rc6 and merge into net-next. That way others should be able to pull the patches without any networking changes. v4: - rebase on top of Mickael's vfork() changes v3: https://lore.kernel.org/all/20240220192235.2953484-1-kuba@kernel.org/ - combine multiple series - change to "list of expected failures" rather than SKIP()-like handling v2: https://lore.kernel.org/all/20240216002619.1999225-1-kuba@kernel.org/ - fix alignment follow up RFC: https://lore.kernel.org/all/20240216004122.2004689-1-kuba@kernel.org/ v1: https://lore.kernel.org/all/20240213154416.422739-1-kuba@kernel.org/ Jakub Kicinski (10): selftests: kselftest_harness: use KSFT_* exit codes 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 selftests: kselftest: add ksft_test_result_code(), handling all exit codes selftests: kselftest_harness: print test name for SKIP selftests: kselftest_harness: separate diagnostic message with # in ksft_test_result_code() selftests: kselftest_harness: let PASS / FAIL provide diagnostic selftests: kselftest_harness: support using xfail selftests: ip_local_port_range: use XFAIL instead of SKIP Mickaël Salaün (2): selftests/landlock: Redefine TEST_F() as TEST_F_FORK() selftests/harness: Merge TEST_F_FORK() into TEST_F() tools/testing/selftests/kselftest.h | 45 +++++ tools/testing/selftests/kselftest_harness.h | 182 +++++++++++------- tools/testing/selftests/landlock/base_test.c | 2 +- tools/testing/selftests/landlock/common.h | 58 +----- tools/testing/selftests/landlock/fs_test.c | 4 +- tools/testing/selftests/landlock/net_test.c | 4 +- .../testing/selftests/landlock/ptrace_test.c | 7 +- .../selftests/net/ip_local_port_range.c | 6 +- tools/testing/selftests/net/tls.c | 2 +- tools/testing/selftests/seccomp/seccomp_bpf.c | 9 +- 10 files changed, 178 insertions(+), 141 deletions(-) -- 2.43.2

[PATCH v1 0/2] selftests: mm: cow: flag vmsplice() hugetlb tests as XFAIL

by David Hildenbrand

The failing hugetlb vmsplice() COW tests keep confusing people, and having tests that have been failing for years and likely will keep failing for years to come because nobody cares enough is rather suboptimal. Let's mark them as XFAIL and document why fixing them is not that easy as it would appear at first sight. More details can be found in [1], especially around how hugetlb pages cannot really be overcommitted, and why we don't particularly care about these vmsplice() leaks for hugetlb -- in contrast to ordinary memory.

[PATCH v3 0/9] Fix Kselftest's vfork() side effects

by Mickaël Salaün

Hi, As reported by Kernel Test Robot [1], some pidfd tests fail. This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration. This series fixes all these side effects by replacing vfork() with clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory) and makes the Kselftest framework more robust. I tried different approaches and I found this one to be the cleaner and less invasive for current test cases. This third series replace improve the clone3_vfork() helper and add Reviewed-by tags. I successfully ran the following tests (using TEST_F and fork/clone/clone3) with this series: - landlock:fs_test - landlock:net_test - landlock:ptrace_test - move_mount_set_group:move_mount_set_group_test - net/af_unix:scm_pidfd - perf_events:remove_on_exec - pidfd:pidfd_getfd_test - pidfd:pidfd_setns_test - seccomp:seccomp_bpf - user_events:abi_test [1] https://lore.kernel.org/oe-lkp/202403291015.1fcfa957-oliver.sang@intel.com Previous versions: v1: https://lore.kernel.org/r/20240426172252.1862930-1-mic@digikod.net v2: https://lore.kernel.org/r/20240429130931.2394118-1-mic@digikod.net Regards, Mickaël Salaün (9): selftests/pidfd: Fix config for pidfd_setns_test selftests/landlock: Fix FS tests when run on a private mount point selftests/harness: Fix fixture teardown selftests/harness: Fix interleaved scheduling leading to race conditions selftests/landlock: Do not allocate memory in fixture data selftests/harness: Constify fixture variants selftests/pidfd: Fix wrong expectation selftests/harness: Share _metadata between forked processes selftests/harness: Fix vfork() side effects tools/testing/selftests/kselftest_harness.h | 113 +++++++++++++----- tools/testing/selftests/landlock/fs_test.c | 83 ++++++++----- tools/testing/selftests/pidfd/config | 2 + .../selftests/pidfd/pidfd_setns_test.c | 2 +- 4 files changed, 135 insertions(+), 65 deletions(-) base-commit: e67572cd2204894179d89bd7b984072f19313b03 -- 2.44.0

[PATCH net-next] selftests: drv-net: add checksum tests

by Willem de Bruijn

From: Willem de Bruijn <willemb(a)google.com> Run tools/testing/selftest/net/csum.c as part of drv-net. This binary covers multiple scenarios, based on arguments given, for both IPv4 and IPv6: - Accept UDP correct checksum - Detect UDP invalid checksum - Accept TCP correct checksum - Detect TCP invalid checksum - Transmit UDP: basic checksum offload - Transmit UDP: zero checksum conversion The test direction is reversed between receive and transmit tests, so that the NIC under test is always the local machine. In total this adds up to 12 testcases, with more to follow. For conciseness, I replaced individual functions with a function factory. It saves a lot of boilerplate, but is a little harder to follow, so partially here as a point for discussion. Also detect hardware offload feature availability using Ethtool netlink and skip tests when either feature is off. This need may be common for offload feature tests and eventually deserving of a thin wrapper in lib.py. Missing are the PF_PACKET based send tests ('-P'). These use virtio_net_hdr to program hardware checksum offload. Which requires looking up the local MAC address and (harder) the MAC of the next hop. I'll have to give it some though how to do that robustly and where that code would belong.

[PATCH] kunit: bail out early in __kunit_test_suites_init() if there are no suites to test

by Scott Mayhew

Commit c72a870926c2 added a mutex to prevent kunit tests from running concurrently. Unfortunately that mutex gets locked during module load regardless of whether the module actually has any kunit tests. This causes a problem for kunit tests that might need to load other kernel modules (e.g. gss_krb5_test loading the camellia module). So check to see if there are actually any tests to run before locking the kunit_run_lock mutex.

[PATCH v2 bpf-next 0/6] selftests/bpf: Add sockaddr tests for kernel networking

by Jordan Rife

This patch series adds test coverage for BPF sockaddr hooks and their interactions with kernel socket functions (i.e. kernel_bind(), kernel_connect(), kernel_sendmsg(), sock_sendmsg(), kernel_getpeername(), and kernel_getsockname()) while also rounding out IPv4 and IPv6 sockaddr hook coverage in prog_tests/sock_addr.c. As with v1 of this patch series, we add regression coverage for the issues addressed by these patches, - commit 0bdf399342c5("net: Avoid address overwrite in kernel_connect") - commit 86a7e0b69bd5("net: prevent rewrite of msg_name in sock_sendmsg()") - commit c889a99a21bf("net: prevent address rewrite in kernel_bind()") - commit 01b2885d9415("net: Save and restore msg_namelen in sock_sendmsg") but broaden the focus a bit. In order to extend prog_tests/sock_addr.c to test these kernel functions, we add a set of new kfuncs that wrap individual socket operations to bpf_testmod and invoke them through set of corresponding SYSCALL programs (progs/sock_addr_kern.c). Each test case can be configured to use a different set of "sock_ops" depending on whether it is testing kernel calls (kernel_bind(), kernel_connect(), etc.) or system calls (bind(), connect(), etc.). ======= Patches ======= * Patch 1 fixes the sock_addr bind test program to work for big endian architectures such as s390x. * Patch 2 introduces the new kfuncs to bpf_testmod. * Patch 3 introduces the BPF program which allows us to invoke these kfuncs invividually from the test program. * Patch 4 lays the groundwork for IPv4 and IPv6 sockaddr hook coverage by migrating much of the environment setup logic from bpf/test_sock_addr.sh into prog_tests/sock_addr.c and adds test cases to cover bind4/6, connect4/6, sendmsg4/6 and recvmsg4/6 hooks. * Patch 5 makes the set of socket operations for each test case configurable, laying the groundwork for Patch 6. * Patch 6 introduces two sets of sock_ops that invoke the kernel equivalents of connect(), bind(), etc. and uses these to add coverage for the kernel socket functions. ======= Changes ======= v1->v2 ------ * Dropped test_progs/sock_addr_kern.c and the sock_addr_kern test module in favor of simply expanding bpf_testmod and test_progs/sock_addr.c. * Migrated environment setup logic from bpf/test_sock_addr.sh into prog_tests/sock_addr.c rather than invoking the script from the test program. * Added kfuncs to bpf_testmod as well as the sock_addr_kern BPF program to enable us to invoke kernel socket functions from test_progs/sock_addr.c. * Added test coverage for kernel socket functions to test_progs/sock_addr.c.

[PATCH v4 13/16] riscv: hwprobe: Add thead vendor extension probing

by Charlie Jenkins

Add a new hwprobe key "RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0" which allows userspace to probe for the new RISCV_ISA_VENDOR_EXT_XTHEADVECTOR vendor extension. This new key will allow userspace code to probe for which thead vendor extensions are supported. This API is modeled to be consistent with RISCV_HWPROBE_KEY_IMA_EXT_0. The bitmask returned will have each bit corresponding to a supported thead vendor extension of the cpumask set.

[PATCH] selftests/harness: fix many "format string is empty" warnings

by John Hubbard

In order to build with clang at all, in order to see these symptoms, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...clang emits a "format string is empty" warning. (gcc also emits a similar warning.) Fix by passing NULL, instead of "", for the msg argument to ksft_test_result_code(). This removes dozens of warnings and a few errors (some tests have -Werror set).

[PATCH net-next 0/6] selftests: net: page_poll allocation error injection

by Jakub Kicinski

Add a test for exercising driver memory allocation failure paths. page pool is a bit tricky to inject errors into at the page allocator level because of the bulk alloc and recycling, so add explicit error injection support "in front" of the caches. Add a test to exercise that using only the standard APIs. This is the first useful test for the new tests with an endpoint. There's no point testing netdevsim here, so this is also the first HW-only test in Python. I'm not super happy with the traffic generation using iperf3, my initial approach was to use mausezahn. But it turned out to be 5x slower in terms of PPS. Hopefully this is good enough for now.

[PATCH v1] selftests: mm: gup_longterm: test unsharing logic when R/O pinning

by David Hildenbrand

In our FOLL_LONGTERM tests, we prefault the page tables for the GUP-fast test cases to be able to find a PTE and exercise the "longterm pinning allowed" logic on the GUP-fast path where possible. For now, we always prefault the page tables writable, resulting in PTEs that are writable. Let's cover more cases to also test if our unsharing logic works as expected (and is able to make progress when there is nothing to unshare) by mprotect'ing the range R/O when R/O-pinning, so we don't get PTEs that are writable. This change would have found an issue introduced by commit a12083d721d7 ("mm/gup: handle hugepd for follow_page()"), whereby R/O pinning was not able to make progress in all cases, because unsharing logic was not provided with the VMA to decide at some point that long-term R/O pinning a !anon page is fine.

[PATCH v8 00/24] RISC-V SBI v2.0 PMU improvements and Perf sampling in KVM guest

by Atish Patra

This series implements SBI PMU improvements done in SBI v2.0[1] i.e. PMU snapshot and fw_read_hi() functions. SBI v2.0 introduced PMU snapshot feature which allows the SBI implementation to provide counter information (i.e. values/overflow status) via a shared memory between the SBI implementation and supervisor OS. This allows to minimize the number of traps in when perf being used inside a kvm guest as it relies on SBI PMU + trap/emulation of the counters. The current set of ratified RISC-V specification also doesn't allow scountovf to be trap/emulated by the hypervisor. The SBI PMU snapshot bridges the gap in ISA as well and enables perf sampling in the guest. However, LCOFI in the guest only works via IRQ filtering in AIA specification. That's why, AIA has to be enabled in the hardware (at least the Ssaia extension) in order to use the sampling support in the perf. Here are the patch wise implementation details. PATCH 1,4,7,8,9,10,11,15 : Generic cleanups/improvements. PATCH 2,3,14 : FW_READ_HI function implementation PATCH 5-6: Add PMU snapshot feature in sbi pmu driver PATCH 12-13: KVM implementation for snapshot and sampling in kvm guests PATCH 16-17: Generic improvements for kvm selftests PATCH 18-22: KVM selftests for SBI PMU extension The series is based on v6.9-rc4 and is available at: https://github.com/atishp04/linux/tree/kvm_pmu_snapshot_v8 The kvmtool patch is also available at: https://github.com/atishp04/kvmtool/tree/sscofpmf It also requires Ssaia ISA extension to be present in the hardware in order to get perf sampling support in the guest. In Qemu virt machine, it can be done by the following config. ``` -cpu rv64,sscofpmf=true,x-ssaia=true ``` There is no other dependencies on AIA apart from that. Thus, Ssaia must be disabled for the guest if AIA patches are not available. Here is the example command. ``` ./lkvm-static run -m 256 -c2 --console serial -p "console=ttyS0 earlycon" --disable-ssaia -k ./Image --debug ``` The series has been tested only in Qemu.

[PATCH] kselftest: Add a ksft_perror() helper

by Edward Liaw

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 907f33028871fa7c9a3db1efd467b78ef82cce20 ] The standard library perror() function provides a convenient way to print an error message based on the current errno but this doesn't play nicely with KTAP output. Provide a helper which does an equivalent thing in a KTAP compatible format. nolibc doesn't have a strerror() and adding the table of strings required doesn't seem like a good fit for what it's trying to do so when we're using that only print the errno.

[PATCH V3] KVM: selftests: Add a new option to rseq_test

by Zide Chen

Currently, the migration worker delays 1-10 us, assuming that one KVM_RUN iteration only takes a few microseconds. But if the CPU low power wakeup latency is large enough, for example, hundreds or even thousands of microseconds deep C-state exit latencies on x86 server CPUs, it may happen that it's not able to wakeup the target CPU before the migration worker starts to migrate the vCPU thread to the next CPU. If the system workload is light, most CPUs could be at a certain low power state, which may result in less successful migrations and fail the migration/KVM_RUN ratio sanity check. But this is not supposed to be deemed a test failure. This patch adds a command line option to skip the sanity check in this case.
