2021-07-16selftests/bpf: Add dump type data tests to btf dump testsAlan Maguire1-0/+598
Test various type data dumping operations by comparing expected format with the dumped string; an snprintf-style printf function is used to record the string dumped. Also verify overflow handling where the data passed does not cover the full size of a type, such as would occur if a tracer has a portion of the 8k "struct task_struct".

2021-07-16sock_map: Lift socket state restriction for datagram socketsCong Wang1-3/+5
TCP and other connection oriented sockets have accept() for each incoming connection on the server side, hence they can just insert those fd's from accept() to sockmap, which are of course established. Now with datagram sockets begin to support sockmap and redirection, the restriction is no longer applicable to them, as they have no accept(). So we have to lift this restriction for them. This is fine, because inside bpf_sk_redirect_map() we still have another socket status check, sock_map_redirect_allowed(), as a guard. This also means they do not have to be removed from sockmap when disconnecting.

Check that map-in-map supports bpf timers.

"while true; do ./test_progs -t timer_mim; done" is a great stress test.

2021-07-12kunit: tool: Fix error messages for cases of no tests and wrong TAP headerRae Moar4-5/+19
This patch addresses misleading error messages reported by kunit_tool in two cases. First, in the case of TAP output having an incorrect header format or missing a header, the parser used to output an error message of 'no tests run!'. Now the parser outputs an error message of 'could not parse test results!'. As an example: Before: $ ./tools/testing/kunit/kunit.py parse /dev/null [ERROR] no tests run! ... After: $ ./tools/testing/kunit/kunit.py parse /dev/null [ERROR] could not parse test results! ... Second, in the case of TAP output with the correct header but no tests, the parser used to output an error message of 'could not parse test results!'. Now the parser outputs an error message of 'no tests run!'. As an example: Before: $ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse [ERROR] could not parse test results! After: $ echo -e 'TAP version 14\n1..0' | ./tools/testing/kunit/kunit.py parse [ERROR] no tests run! Additionally, this patch also corrects the tests in kunit_tool_test.py and adds a test to check the error in the case of TAP output with the correct header but no tests.

This then moves around subprog start/end insn index and poke descriptor insn index to ensure that verify and JIT will continue to track these correctly.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fpu updates from Thomas Gleixner: "Fixes and improvements for FPU handling on x86: - Prevent sigaltstack out of bounds writes. The kernel unconditionally writes the FPU state to the alternate stack without checking whether the stack is large enough to accomodate it. Check the alternate stack size before doing so and in case it's too small force a SIGSEGV instead of silently corrupting user space data. - MINSIGSTKZ and SIGSTKSZ are constants in signal.h and have never been updated despite the fact that the FPU state which is stored on the signal stack has grown over time which causes trouble in the field when AVX512 is available on a CPU. The kernel does not expose the minimum requirements for the alternate stack size depending on the available and enabled CPU features. ARM already added an aux vector AT_MINSIGSTKSZ for the same reason. Add it to x86 as well. - A major cleanup of the x86 FPU code. The recent discoveries of XSTATE related issues unearthed quite some inconsistencies, duplicated code and other issues. The fine granular overhaul addresses this, makes the code more robust and maintainable, which allows to integrate upcoming XSTATE related features in sane ways" * tag 'x86-fpu-2021-07-07' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (74 commits) x86/fpu/xstate: Clear xstate header in copy_xstate_to_uabi_buf() again x86/fpu/signal: Let xrstor handle the features to init x86/fpu/signal: Handle #PF in the direct restore path x86/fpu: Return proper error codes from user access functions x86/fpu/signal: Split out the direct restore code x86/fpu/signal: Sanitize copy_user_to_fpregs_zeroing() x86/fpu/signal: Sanitize the xstate check on sigframe x86/fpu/signal: Remove the legacy alignment check x86/fpu/signal: Move initial checks into fpu__restore_sig() x86/fpu: Mark init_fpstate __ro_after_init x86/pkru: Remove xstate fiddling from write_pkru() x86/fpu: Don't store PKRU in xstate in fpu_reset_fpstate() x86/fpu: Remove PKRU handling from switch_fpu_finish() x86/fpu: Mask PKRU from kernel XRSTOR[S] operations x86/fpu: Hook up PKRU into ptrace() x86/fpu: Add PKRU storage outside of task XSAVE buffer x86/fpu: Dont restore PKRU in fpregs_restore_userspace() x86/fpu: Rename xfeatures_mask_user() to xfeatures_mask_uabi() x86/fpu: Move FXSAVE_LEAK quirk info __copy_kernel_to_fpregs() x86/fpu: Rename __fpregs_load_activate() to fpregs_restore_userregs() ...
