[V3][PATCH] selftests/x86: Fix error: variably modified 'altstack_data' at file scope

by Jun Miao

Based on glibc 2.33 -> 2.34, there is one new feature: NEWS for version 2.34 ===================== Major new features: * Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ) and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports dynamic sized register sets for modern architectural features like Arm SVE. ===================== If _SC_SIGSTKSZ_SOURCE or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are redefined as: /* Default stack size for a signal handler: sysconf (SC_SIGSTKSZ). */ # undef SIGSTKSZ # define SIGSTKSZ sysconf (_SC_SIGSTKSZ) /* Minimum stack size for a signal handler: SIGSTKSZ. */ # undef MINSIGSTKSZ # define MINSIGSTKSZ SIGSTKSZ Compilation will fail if the source assumes constant MINSIGSTKSZ or SIGSTKSZ. Build error with the GNU C Library 2.34: DEBUG: | sigreturn.c:150:13: error: variably modified 'altstack_data' at file scope | sigreturn.c:150:13: error: variably modified 'altstack_data' at file scope DEBUG: | 150 | static char altstack_data[SIGSTKSZ]; | 150 | static char altstack_data[SIGSTKSZ]; DEBUG: | | ^~~~~~~~~~~~~ DEBUG: | single_step_syscall.c:60:22: error: variably modified 'altstack_data' at file scope DEBUG: | 60 | static unsigned char altstack_data[SIGSTKSZ]; DEBUG: | | ^~~~~~~~~~~~~ Link: https://sourceware.org/pipermail/libc-alpha/2021-January/121996.html Link: https://sourceware.org/pipermail/libc-alpha/2021-August/129718.html Suggested-by: Jianwei Hu <jianwei.hu(a)windriver.com> Signed-off-by: Jun Miao <jun.miao(a)windriver.com> --- tools/testing/selftests/x86/mov_ss_trap.c | 4 ++-- tools/testing/selftests/x86/sigreturn.c | 7 +++---- tools/testing/selftests/x86/single_step_syscall.c | 4 ++-- tools/testing/selftests/x86/syscall_arg_fault.c | 7 +++---- 4 files changed, 10 insertions(+), 12 deletions(-) diff --git a/tools/testing/selftests/x86/mov_ss_trap.c b/tools/testing/selftests/x86/mov_ss_trap.c index 6da0ac3f0135..cc3de6ff9fba 100644 --- a/tools/testing/selftests/x86/mov_ss_trap.c +++ b/tools/testing/selftests/x86/mov_ss_trap.c @@ -47,7 +47,6 @@ unsigned short ss; extern unsigned char breakpoint_insn[]; sigjmp_buf jmpbuf; -static unsigned char altstack_data[SIGSTKSZ]; static void enable_watchpoint(void) { @@ -250,13 +249,14 @@ int main() if (sigsetjmp(jmpbuf, 1) == 0) { printf("[RUN]\tMOV SS; SYSENTER\n"); stack_t stack = { - .ss_sp = altstack_data, + .ss_sp = malloc(sizeof(char) * SIGSTKSZ), .ss_size = SIGSTKSZ, }; if (sigaltstack(&stack, NULL) != 0) err(1, "sigaltstack"); sethandler(SIGSEGV, handle_and_longjmp, SA_RESETHAND | SA_ONSTACK); nr = SYS_getpid; + free(stack.ss_sp); /* Clear EBP first to make sure we segfault cleanly. */ asm volatile ("xorl %%ebp, %%ebp; mov %[ss], %%ss; SYSENTER" : "+a" (nr) : [ss] "m" (ss) : "flags", "rcx" diff --git a/tools/testing/selftests/x86/sigreturn.c b/tools/testing/selftests/x86/sigreturn.c index 57c4f67f16ef..5d7961a5f7f6 100644 --- a/tools/testing/selftests/x86/sigreturn.c +++ b/tools/testing/selftests/x86/sigreturn.c @@ -138,9 +138,6 @@ static unsigned short LDT3(int idx) return (idx << 3) | 7; } -/* Our sigaltstack scratch space. */ -static char altstack_data[SIGSTKSZ]; - static void sethandler(int sig, void (*handler)(int, siginfo_t *, void *), int flags) { @@ -771,7 +768,8 @@ int main() setup_ldt(); stack_t stack = { - .ss_sp = altstack_data, + /* Our sigaltstack scratch space. */ + .ss_sp = malloc(sizeof(char) * SIGSTKSZ), .ss_size = SIGSTKSZ, }; if (sigaltstack(&stack, NULL) != 0) @@ -872,5 +870,6 @@ int main() total_nerrs += test_nonstrict_ss(); #endif + free(stack.ss_sp); return total_nerrs ? 1 : 0; } diff --git a/tools/testing/selftests/x86/single_step_syscall.c b/tools/testing/selftests/x86/single_step_syscall.c index 120ac741fe44..9a30f443e928 100644 --- a/tools/testing/selftests/x86/single_step_syscall.c +++ b/tools/testing/selftests/x86/single_step_syscall.c @@ -57,7 +57,6 @@ static void clearhandler(int sig) static volatile sig_atomic_t sig_traps, sig_eflags; sigjmp_buf jmpbuf; -static unsigned char altstack_data[SIGSTKSZ]; #ifdef __x86_64__ # define REG_IP REG_RIP @@ -210,7 +209,7 @@ int main() unsigned long nr = SYS_getpid; printf("[RUN]\tSet TF and check SYSENTER\n"); stack_t stack = { - .ss_sp = altstack_data, + .ss_sp = malloc(sizeof(char) * SIGSTKSZ), .ss_size = SIGSTKSZ, }; if (sigaltstack(&stack, NULL) != 0) @@ -219,6 +218,7 @@ int main() SA_RESETHAND | SA_ONSTACK); sethandler(SIGILL, print_and_longjmp, SA_RESETHAND); set_eflags(get_eflags() | X86_EFLAGS_TF); + free(stack.ss_sp); /* Clear EBP first to make sure we segfault cleanly. */ asm volatile ("xorl %%ebp, %%ebp; SYSENTER" : "+a" (nr) :: "flags", "rcx" #ifdef __x86_64__ diff --git a/tools/testing/selftests/x86/syscall_arg_fault.c b/tools/testing/selftests/x86/syscall_arg_fault.c index bff474b5efc6..461fa41a4d02 100644 --- a/tools/testing/selftests/x86/syscall_arg_fault.c +++ b/tools/testing/selftests/x86/syscall_arg_fault.c @@ -17,9 +17,6 @@ #include "helpers.h" -/* Our sigaltstack scratch space. */ -static unsigned char altstack_data[SIGSTKSZ]; - static void sethandler(int sig, void (*handler)(int, siginfo_t *, void *), int flags) { @@ -104,7 +101,8 @@ static void sigill(int sig, siginfo_t *info, void *ctx_void) int main() { stack_t stack = { - .ss_sp = altstack_data, + /* Our sigaltstack scratch space. */ + .ss_sp = malloc(sizeof(char) * SIGSTKSZ), .ss_size = SIGSTKSZ, }; if (sigaltstack(&stack, NULL) != 0) @@ -233,5 +231,6 @@ int main() set_eflags(get_eflags() & ~X86_EFLAGS_TF); #endif + free(stack.ss_sp); return 0; } -- 2.32.0

KernelCI Hackfest #2 - Sept 6-10 2021

by Guillaume Tucker

The first KernelCI hackfest[1] early June was successful in getting a number of kernel developers to work alongside the core KernelCI team. Test coverage was increased in particular with kselftest, LTP, KUnit and a new test suite for libcamera. We're now improving documentation and tooling to make it easier for anyone to get started. Find out more about KernelCI on https://kernelci.org. The second hackfest is scheduled for the 6th-10th September. It should be a good opportunity to start discussing and working on upstream kernel testing topics ahead of the Linux Plumbers Conference[2]. Here's the project board where anyone can already add some ideas: https://github.com/orgs/kernelci/projects/5 There is no registration system, but please reply to this email or send a message on IRC (#kernelci libera.chat) or kernelci.slack.com if you would like to take part so you'll get email updates and invitations to the meetings and open hours sessions online. You may just drop in and out at any point during the hackfest as you see fit. The hackfest features: * Daily open hours online using Big Blue Button to discuss things and get support from the KernelCI team * KernelCI team members available across most time zones to provide quick feedback * A curated list of topics and a project board to help set objectives and coordinate efforts between all contributors As always, KernelCI is at the service of the kernel community so please share any feedback you may have to help shape this upcoming hackfest in the best possible way. Thanks, Guillaume [1] https://foundation.kernelci.org/blog/2021/06/24/the-first-ever-kernelci-hac… [2] https://www.linuxplumbersconf.org/event/11/page/104-accepted-microconferenc…

Please find below some extra information for the KernelCI Hackfest which is taking place next week. We're expecting at least some contributors from the Civil Infrastructure Platform project, the Google Chrome OS kernel team, Collabora kernel developers and a few more from the wider Linux kernel community. If you need any direct support, please reply to this email or ask on kernelci.slack.com or IRC #kernelci (libera.chat). > Here's the project board where anyone can already add some ideas: > > https://github.com/orgs/kernelci/projects/5 In order to add an issue to the workboard, please first create one in a KernelCI GitHub repository such as kernelci-core: https://github.com/kernelci/kernelci-core/issues Each contributor to the hackfest should be added to the KernelCI "hackers" team, which has permission to edit the workboard. If you aren't part of this team yet, please ask and you'll be invited. Note: Having a GitHub account is not mandatory for taking part in the hackfest. It's mainly there to facilitate coordination, even though it is required in order to contribute to the KernelCI GitHub repositories. Contributions as part of the hackfest may also be in the kernel tree such as improvements to kselftest, KUnit or bug fixes, or other test suites such as LTP etc. > The hackfest features: > > * Daily open hours online using Big Blue Button to discuss things > and get support from the KernelCI team > > * KernelCI team members available across most time zones to provide > quick feedback > > * A curated list of topics and a project board to help set > objectives and coordinate efforts between all contributors Please see the table below with the proposed daily open hours to accommodate most time zones: Region Zone Time 1 Time 2 East Asia GMT+10 17:00-19:00 03:00-05:00 Europe GMT+2 09:00-11:00 19:00-21:00 UTC 07:00-09:00 17:00-19:00 West America GMT-7 00:00-02:00 10:00-12:00 They will be held as a Big Blue Button virtual conference with the same URL as the last hackfest. It's not being shared publicly to avoid any potential abuse, so please ask if you don't have it already. On Monday, the focus should be put on getting started and reviewing the backlog on the hackfest workboard to distribute things among people or help new contributors find topics suitable for them. Open hours are otherwise opportunities to get more direct support from the KernelCI team or discuss any topic. See you there!

[PATCH v3 0/5] KVM: rseq: Fix and a test for a KVM+rseq bug

by Sean Christopherson

Patch 1 fixes a KVM+rseq bug where KVM's handling of TIF_NOTIFY_RESUME, e.g. for task migration, clears the flag without informing rseq and leads to stale data in userspace's rseq struct. Patch 2 is a cleanup to try and make future bugs less likely. It's also a baby step towards moving and renaming tracehook_notify_resume() since it has nothing to do with tracing. Patch 3 is a fix/cleanup to stop overriding x86's unistd_{32,64}.h when the include path (intentionally) omits tools' uapi headers. KVM's selftests do exactly that so that they can pick up the uapi headers from the installed kernel headers, and still use various tools/ headers that mirror kernel code, e.g. linux/types.h. This allows the new test in patch 4 to reference __NR_rseq without having to manually define it. Patch 4 is a regression test for the KVM+rseq bug. Patch 5 is a cleanup made possible by patch 3. Based on commit 835d31d319d9 ("Merge tag 'media/v5.15-1' of ..."). v3: - Collect Ack/Review. [Mathieu, Ben] - Add explicit smp_wmb() instead of relying on atomic_inc() to do a full barrier. [Mathieu] - Add lots and lots of comments in the selftest, especially around why the migration thread needs a udelay(). [Mathieu] - Delay between 1us and 10us to reduce the odds of having a hard dependency on arch/kernel behavior. [Mathieu] - Dropped an s390 change in patch 2 after a rebase to upstream master. v2: - https://lkml.kernel.org/r/20210820225002.310652-1-seanjc@google.com - Don't touch rseq_cs when handling KVM case so that rseq_syscall() will still detect a naughty userspace. [Mathieu] - Use a sequence counter + retry in the test to ensure the process isn't migrated between sched_getcpu() and reading rseq.cpu_id, i.e. to avoid a flaky test. [Mathieu] - Add Mathieu's ack for patch 2. - Add more comments in the test. v1: https://lkml.kernel.org/r/20210818001210.4073390-1-seanjc@google.com Sean Christopherson (5): KVM: rseq: Update rseq when processing NOTIFY_RESUME on xfer to KVM guest entry: rseq: Call rseq_handle_notify_resume() in tracehook_notify_resume() tools: Move x86 syscall number fallbacks to .../uapi/ KVM: selftests: Add a test for KVM_RUN+rseq to detect task migration bugs KVM: selftests: Remove __NR_userfaultfd syscall fallback arch/arm/kernel/signal.c | 1 - arch/arm64/kernel/signal.c | 1 - arch/csky/kernel/signal.c | 4 +- arch/mips/kernel/signal.c | 4 +- arch/powerpc/kernel/signal.c | 4 +- include/linux/tracehook.h | 2 + kernel/entry/common.c | 4 +- kernel/rseq.c | 14 +- .../x86/include/{ => uapi}/asm/unistd_32.h | 0 .../x86/include/{ => uapi}/asm/unistd_64.h | 3 - tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 3 + tools/testing/selftests/kvm/rseq_test.c | 236 ++++++++++++++++++ 13 files changed, 257 insertions(+), 20 deletions(-) rename tools/arch/x86/include/{ => uapi}/asm/unistd_32.h (100%) rename tools/arch/x86/include/{ => uapi}/asm/unistd_64.h (83%) create mode 100644 tools/testing/selftests/kvm/rseq_test.c -- 2.33.0.153.gba50c8fa24-goog

[PATCH] kselftests/sched: cleanup the child processes

[PATCH v3] kunit: tool: improve compatibility of kunit_parser with KTAP specification

by Rae Moar

Update to kunit_parser to improve compatibility with KTAP specification including arbitrarily nested tests. Patch accomplishes three major changes: - Use a general Test object to represent all tests rather than TestCase and TestSuite objects. This allows for easier implementation of arbitrary levels of nested tests and promotes the idea that both test suites and test cases are tests. - Print errors incrementally rather than all at once after the parsing finishes to maximize information given to the user in the case of the parser given invalid input and to increase the helpfulness of the timestamps given during printing. Note that kunit.py parse does not print incrementally yet. However, this fix brings us closer to this feature. - Increase compatibility for different formats of input. Arbitrary levels of nested tests supported. Also, test cases and test suites are now supported to be present on the same level of testing. This patch now implements the KTAP specification as described here: https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn6c7NViJxqa…. This patch adjusts the kunit_tool_test.py file to check for the correct outputs from the new parser and adds a new test to check the parsing for a KTAP result log with correct format for multiple nested subtests (test_is_test_passed-all_passed_nested.log). This patch also alters the kunit_json.py file to allow for arbitrarily nested tests. Signed-off-by: Rae Moar <rmoar(a)google.com> Reviewed-by: Brendan Higgins <brendanhiggins(a)google.com> --- Change log from v2: https://lore.kernel.org/linux-kselftest/20210826195505.3066755-1-rmoar@goog… - Fixes bug of type disagreement in kunit_json.py for build_dir - Removes raw_output() - Changes docstrings in kunit_parser.py (class docstring, LineStream docstrings, add_error(), total(), get_status(), all parsing methods) - Fixes bug of not printing diagnostic log in the case of end of lines - Sets default status of all tests to TEST_CRASHED - Adds and prints empty tests with crashed status in case of missing tests - Prints 'subtest' in instance of 1 subtest instead of 'subtests' - Includes checking for 'BUG:' message in search of crash messages in log (note that parse_crash_in_log method could be removed but would require deleting tests in kunit_tool_test.py that include the crash message that is no longer used. If removed, parser would still print log in cases of test crashed or failure, which would now include missing subtests) - Fixes bug of including directives (other than SKIP) in test name when matching name in result line for subtests --- Change log from v1: https://lore.kernel.org/linux-kselftest/20210820200032.2178134-1-rmoar@goog… - Rebase onto kselftest/kunit branch - Add tests to kunit_tool_test.py to check parser is correctly stripping hyphen, producing correct json objects with nested tests, correctly passing kselftest TAP output, and correctly deals with missing test plan. - Fix bug to correctly match test name in instance of a missing test plan. - Fix bug in kunit_tool_test.py pointed out by Daniel where it was not correctly checking for a proper match to the '0 tests run!' error message. Reverts changes back to original. - A few minor changes to commit message using Daniel's comments. - Change docstrings using Daniel's comments to reduce: - Shortens some docstrings to be one-line or just description if it is self explanatory. - Remove explicit respecification of types of parameters and returns because this is already specified in the function annoations. However, some descriptions of the parameters and returns remain and some contain the type for context. Additionally, the types of public attributes of classes remain. - Remove any documentation of 'Return: None' - Remove docstrings of helper methods within other methods --- tools/testing/kunit/kunit_json.py | 56 +- tools/testing/kunit/kunit_parser.py | 1022 ++++++++++++----- tools/testing/kunit/kunit_tool_test.py | 132 ++- .../test_is_test_passed-all_passed_nested.log | 34 + .../test_is_test_passed-kselftest.log | 14 + .../test_is_test_passed-missing_plan.log | 31 + .../kunit/test_data/test_strip_hyphen.log | 16 + 7 files changed, 925 insertions(+), 380 deletions(-) create mode 100644 tools/testing/kunit/test_data/test_is_test_passed-all_passed_nested.log create mode 100644 tools/testing/kunit/test_data/test_is_test_passed-kselftest.log create mode 100644 tools/testing/kunit/test_data/test_is_test_passed-missing_plan.log create mode 100644 tools/testing/kunit/test_data/test_strip_hyphen.log diff --git a/tools/testing/kunit/kunit_json.py b/tools/testing/kunit/kunit_json.py index f5cca5c38cac..746bec72b9ac 100644 --- a/tools/testing/kunit/kunit_json.py +++ b/tools/testing/kunit/kunit_json.py @@ -11,47 +11,47 @@ import os import kunit_parser -from kunit_parser import TestStatus - -def get_json_result(test_result, def_config, build_dir, json_path) -> str: - sub_groups = [] - - # Each test suite is mapped to a KernelCI sub_group - for test_suite in test_result.suites: - sub_group = { - "name": test_suite.name, - "arch": "UM", - "defconfig": def_config, - "build_environment": build_dir, - "test_cases": [], - "lab_name": None, - "kernel": None, - "job": None, - "git_branch": "kselftest", - } - test_cases = [] - # TODO: Add attachments attribute in test_case with detailed - # failure message, see https://api.kernelci.org/schema-test-case.html#get - for case in test_suite.cases: - test_case = {"name": case.name, "status": "FAIL"} - if case.status == TestStatus.SUCCESS: +from kunit_parser import Test, TestResult, TestStatus +from typing import Any, Dict, Optional + +JsonObj = Dict[str, Any] + +def _get_group_json(test: Test, def_config: str, + build_dir: Optional[str]) -> JsonObj: + sub_groups = [] # List[JsonObj] + test_cases = [] # List[JsonObj] + + for subtest in test.subtests: + if len(subtest.subtests): + sub_group = _get_group_json(subtest, def_config, + build_dir) + sub_groups.append(sub_group) + else: + test_case = {"name": subtest.name, "status": "FAIL"} + if subtest.status == TestStatus.SUCCESS: test_case["status"] = "PASS" - elif case.status == TestStatus.TEST_CRASHED: + elif subtest.status == TestStatus.TEST_CRASHED: test_case["status"] = "ERROR" test_cases.append(test_case) - sub_group["test_cases"] = test_cases - sub_groups.append(sub_group) + test_group = { - "name": "KUnit Test Group", + "name": test.name, "arch": "UM", "defconfig": def_config, "build_environment": build_dir, "sub_groups": sub_groups, + "test_cases": test_cases, "lab_name": None, "kernel": None, "job": None, "git_branch": "kselftest", } + return test_group + +def get_json_result(test_result: TestResult, def_config: str, + build_dir: Optional[str], json_path: str) -> str: + test_group = _get_group_json(test_result.test, def_config, build_dir) + test_group["name"] = "KUnit Test Group" json_obj = json.dumps(test_group, indent=4) if json_path != 'stdout': with open(json_path, 'w') as result_path: diff --git a/tools/testing/kunit/kunit_parser.py b/tools/testing/kunit/kunit_parser.py index 6310a641b151..f1b28def3e78 100644 --- a/tools/testing/kunit/kunit_parser.py +++ b/tools/testing/kunit/kunit_parser.py @@ -1,11 +1,15 @@ # SPDX-License-Identifier: GPL-2.0 # -# Parses test results from a kernel dmesg log. +# Parses KTAP test results from a kernel dmesg log and incrementally prints +# results with reader-friendly format.

[RFC v2 net-next 0/2] Add RTNL interface for SyncE

by Maciej Machnikowski

Synchronous Ethernet networks use a physical layer clock to syntonize the frequency across different network elements. Multiple reference clock sources can be used. Clocks recovered from PHY ports on the RX side or external sources like 1PPS GPS, etc. This patch series introduces basic interface for reading the DPLL state on a SyncE capable device. This state gives us information about the source of the syntonization signal and whether the DPLL circuit is tuned to the incoming signal. Next steps: - add interface to enable recovered clocks and get information about them v2: - removed whitespace changes - fix issues reported by test robot Maciej Machnikowski (2): rtnetlink: Add new RTM_GETSYNCESTATE message to get SyncE status ice: add support for reading SyncE DPLL state drivers/net/ethernet/intel/ice/ice.h | 5 ++ .../net/ethernet/intel/ice/ice_adminq_cmd.h | 34 ++++++++ drivers/net/ethernet/intel/ice/ice_common.c | 62 +++++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 4 + drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_main.c | 55 +++++++++++++ drivers/net/ethernet/intel/ice/ice_ptp.c | 35 +++++++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 44 +++++++++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 22 ++++++ include/linux/netdevice.h | 6 ++ include/uapi/linux/if_link.h | 43 +++++++++++ include/uapi/linux/rtnetlink.h | 11 ++- net/core/rtnetlink.c | 77 +++++++++++++++++++ security/selinux/nlmsgtab.c | 3 +- 14 files changed, 399 insertions(+), 5 deletions(-) -- 2.26.3
