2023-08-16kselftest/arm64: add jscvt feature to hwcap testZeng Heng1-0/+13
Add the jscvt feature check in the set of hwcap tests. Due to the requirement of jscvt feature, a compiler configuration of v8.3 or above is needed to support assembly. Therefore, hand encode is used here instead.

2023-08-16kselftest/arm64: build BTI tests in output directoryAndre Przywara2-27/+20
The arm64 BTI selftests are currently built in the source directory, then the generated binaries are copied to the output directory. This leaves the object files around in a potentially otherwise pristine source tree, tainting it for out-of-tree kernel builds. Prepend $(OUTPUT) to every reference to an object file in the Makefile, and remove the extra handling and copying. This puts all generated files under the output directory.

2023-08-11kselftest/arm64: Size sycall-abi buffers for the actual maximum VLMark Brown1-15/+23
Our ABI opts to provide future proofing by defining a much larger SVE_VQ_MAX than the architecture actually supports. Since we use this define to control the size of our vector data buffers this results in a lot of overhead when we initialise which can be a very noticable problem in emulation, we fill buffers that are orders of magnitude larger than we will ever actually use even with virtual platforms that provide the full range of architecturally supported vector lengths. Define and use the actual architecture maximum to mitigate this.

2023-08-11kselftest/arm64: add test item that support to capturing the SIGBUS signalZeng Heng1-10/+23
Some enhanced features, such as the LSE2 feature, do not result in SILLILL if LSE2 is missing and LSE is present, but will generate a SIGBUS exception when atomic access unaligned. Therefore, we add test item to test this type of features. Notice that testing for SIGBUS only makes sense after make sure that the instruction does not cause a SIGILL signal.

2023-08-04kselftest/arm64: Exit streaming mode after collecting signal contextMark Brown1-1/+24
When we collect a signal context with one of the SME modes enabled we will have enabled that mode behind the compiler and libc's back so they may issue some instructions not valid in streaming mode, causing spurious failures. For the code prior to issuing the BRK to trigger signal handling we need to stay in streaming mode if we were already there since that's a part of the signal context the caller is trying to collect. Unfortunately this code includes a memset() which is likely to be heavily optimised and is likely to use FP instructions incompatible with streaming mode. We can avoid this happening by open coding the memset(), inserting a volatile assembly statement to avoid the compiler recognising what's being done and doing something in optimisation. This code is not performance critical so the inefficiency should not be an issue. After collecting the context we can simply exit streaming mode, avoiding these issues. Use a full SMSTOP for safety to prevent any issues appearing with ZA.

We just fixed an issue where changing the SVE VL while SME was active could result in us attempting to save the streaming mode SVE vectors without any backing storage. Add a test case which provokes that issue, ideally we should also verify that the contents of ZA are unaffected by any of what we did. Note that since we need to keep streaming mode enabled we can't use any syscalls to trigger the issue, we have to sit in a loop in usersapce and hope to be preempted. The chosen numbers trigger with defconfig on all the virtual platforms for me, this won't be 100% on all systems but avoid an overcomplicated test implementation.

2023-07-14selftests/arm64: fix build failure during the "emit_tests" stepJohn Hubbard1-1/+1
The build failure reported in [1] occurred because commit <9fc96c7c19df> ("selftests: error out if kernel header files are not yet built") added a new "kernel_header_files" dependency to "all", and that triggered another, pre-existing problem. Specifically, the arm64 selftests override the emit_tests target, and that override improperly declares itself to depend upon the "all" target. This is a problem because the "emit_tests" target in lib.mk was not intended to be overridden. emit_tests is a very simple, sequential build target that was originally invoked from the "install" target, which in turn, depends upon "all". That approach worked for years. But with 9fc96c7c19df in place, emit_tests failed, because it does not set up all of the elaborate things that "install" does. And that caused the new "kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being correct) to fail. Some detail: The "all" target is .PHONY. Therefore, each target that depends on "all" will cause it to be invoked again, and because dependencies are managed quite loosely in the selftests Makefiles, many things will run, even "all" is invoked several times in immediate succession. So this is not a "real" failure, as far as build steps go: everything gets built, but "all" reports a problem when invoked a second time from a bad environment. To fix this, simply remove the unnecessary "all" dependency from the overridden emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all". An alternative approach would be to harden the emit_tests target so that it can depend upon "all", but that's a lot more complicated and hard to get right, and doesn't seem worth it, especially given that emit_tests should probably not be overridden at all.

This approach, when combined with commit 9fc96c7c19df ("selftests: error out if kernel header files are not yet built"), has caused build failures [1] on arm64, and is likely to cause similar failures for riscv. To fix this, simply remove the unnecessary "all" dependency from the emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all".

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in. But the parsing failed to handle this case. - Add selftest to struct sizes for user events - Fix sample code for direct trampolines. The sample code for direct trampolines attached to handle_mm_fault(). But the prototype changed and the direct trampoline sample code was not updated. Direct trampolines needs to have the arguments correct otherwise it can fail or crash the system. - Remove unused ftrace_regs_caller_ret() prototype. - Quiet false positive of FORTIFY_SOURCE Due to backward compatibility, the structure used to save stack traces in the kernel had a fixed size of 8. This structure is exported to user space via the tracing format file. A change was made to allow more than 8 functions to be recorded, and user space now uses the size field to know how many functions are actually in the stack. But the structure still has size of 8 (even though it points into the ring buffer that has the required amount allocated to hold a full stack. This was fine until the fortifier noticed that the memcpy(&entry->caller, stack, size) was greater than the 8 functions and would complain at runtime about it. Hide this by using a pointer to the stack location on the ring buffer instead of using the address of the entry structure caller field. - Fix a deadloop in reading trace_pipe that was caused by a mismatch between ring_buffer_empty() returning false which then asked to read the data, but the read code uses rb_num_of_entries() that returned zero, and causing a infinite "retry". - Fix a warning caused by not using all pages allocated to store ftrace functions, where this can happen if the linker inserts a bunch of "NULL" entries, causing the accounting of how many pages needed to be off. - Fix histogram synthetic event crashing when the start event is removed and the end event is still using a variable from it - Fix memory leak in freeing iter->temp in tracing_release_pipe() * tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix memory leak of iter->temp when reading trace_pipe tracing/histograms: Add histograms to hist_vars if they have referenced variables tracing: Stop FORTIFY_SOURCE complaining about stack trace caller ftrace: Fix possible warning on checking all pages used in ftrace_process_locs() ring-buffer: Fix deadloop issue on reading trace_pipe tracing: arm64: Avoid missing-prototype warnings selftests/user_events: Test struct size match cases tracing/user_events: Fix struct arg size match check x86/ftrace: Remove unsued extern declaration ftrace_regs_caller_ret() arm64: ftrace: Add direct call trampoline samples support samples: ftrace: Save required argument registers in sample trampolines

Use the bpf_timer_set_callback helper to mark timer_cb as an async callback, and put a direct call to timer_cb in the main subprog. As the check_stack_max_depth happens after the do_check pass, the order does not matter. Without the previous fix, the test passes successfully.

2023-07-05selftests: mptcp: pm_nl_ctl: fix 32-bit supportMatthieu Baerts1-5/+5
When using pm_nl_ctl to validate userspace path-manager's behaviours, it was failing on 32-bit architectures ~half of the time. pm_nl_ctl was not reporting any error but the command was not doing what it was expected to do. As a result, the expected linked event was not triggered after and the test failed. This is due to the fact the token given in argument to the application was parsed as an integer with atoi(): in a 32-bit arch, if the number was bigger than INT_MAX, 2147483647 was used instead. This can simply be fixed by using strtoul() instead of atoi(). The errors have been seen "by chance" when manually looking at the results from LKFT.
