[PATCH v2 0/4] selftests/seccomp: Refactor change_syscall()

by Kees Cook

v1: https://lore.kernel.org/lkml/20200912110820.597135-1-keescook@chromium.org v2: - Took Acked patches into -next - refactored powerpc syscall setting implementation - refactored clone3 args implementation Hi, This finishes the refactoring of the seccomp selftest logic used in for ptrace syscall number/return handling for powerpc. Additionally fixes clone3 (which seccomp depends on for testing) to run under MIPS where an old struct clone_args has become visible. (FWIW, I expect to take these via the seccomp tree.) Thanks, Kees Cook (4): selftests/seccomp: Record syscall during ptrace entry selftests/seccomp: Allow syscall nr and ret value to be set separately selftests/seccomp: powerpc: Set syscall return during ptrace syscall exit selftests/clone3: Avoid OS-defined clone_args tools/testing/selftests/clone3/clone3.c | 45 +++---- .../clone3/clone3_cap_checkpoint_restore.c | 4 +- .../selftests/clone3/clone3_clear_sighand.c | 2 +- .../selftests/clone3/clone3_selftests.h | 24 ++-- .../testing/selftests/clone3/clone3_set_tid.c | 4 +- tools/testing/selftests/seccomp/seccomp_bpf.c | 120 ++++++++++++++---- 6 files changed, 131 insertions(+), 68 deletions(-) -- 2.25.1

[PATCH 00/15] selftests/seccomp: Refactor change_syscall()

by Kees Cook

Hi, This refactors the seccomp selftest macros used in change_syscall(), in an effort to remove special cases for mips, arm, arm64, and xtensa, which paves the way for powerpc fixes. I'm not entirely done testing, but all-arch build tests and x86_64 selftests pass. I'll be doing arm, arm64, and i386 selftests shortly, but I currently don't have an easy way to check xtensa, mips, nor powerpc. Any help there would be appreciated! (FWIW, I expect to take these via the seccomp tree.) Thanks, -Kees Kees Cook (15): selftests/seccomp: Refactor arch register macros to avoid xtensa special case selftests/seccomp: Provide generic syscall setting macro selftests/seccomp: mips: Define SYSCALL_NUM_SET macro selftests/seccomp: arm: Define SYSCALL_NUM_SET macro selftests/seccomp: arm64: Define SYSCALL_NUM_SET macro selftests/seccomp: mips: Remove O32-specific macro selftests/seccomp: Remove syscall setting #ifdefs selftests/seccomp: Convert HAVE_GETREG into ARCH_GETREG/ARCH_SETREG selftests/seccomp: Convert REGSET calls into ARCH_GETREG/ARCH_SETREG selftests/seccomp: Avoid redundant register flushes selftests/seccomp: Remove SYSCALL_NUM_RET_SHARE_REG in favor of SYSCALL_RET_SET selftests/seccomp: powerpc: Fix seccomp return value testing selftests/seccomp: powerpc: Set syscall return during ptrace syscall exit selftests/clone3: Avoid OS-defined clone_args selftests/seccomp: Use __NR_mknodat instead of __NR_mknod .../selftests/clone3/clone3_selftests.h | 16 +- tools/testing/selftests/seccomp/seccomp_bpf.c | 313 ++++++++++-------- 2 files changed, 184 insertions(+), 145 deletions(-) -- 2.25.1

[PATCH v2 0/6] selftests: arm64: Add floating point selftests

by Mark Brown

This series imports a series of tests for FPSIMD and SVE originally written by Dave Martin to the tree. Since these extensions have some overlap in terms of register usage and must sometimes be tested together they're dropped into a single directory. I've adapted some of the tests to run within the kselftest framework but there are also some stress tests here that are intended to be run as soak tests so aren't suitable for running by default and are mostly just integrated with the build system. There doesn't seem to be a more suitable home for those stress tests and they are very useful for work on these areas of the code so it seems useful to have them somewhere in tree. v2: Rebased onto v5.9-rc1 Mark Brown (6): selftests: arm64: Test case for enumeration of SVE vector lengths selftests: arm64: Add test for the SVE ptrace interface selftests: arm64: Add stress tests for FPSMID and SVE context switching selftests: arm64: Add utility to set SVE vector lengths selftests: arm64: Add wrapper scripts for stress tests selftests: arm64: Add build and documentation for FP tests tools/testing/selftests/arm64/Makefile | 2 +- tools/testing/selftests/arm64/fp/.gitignore | 5 + tools/testing/selftests/arm64/fp/Makefile | 17 + tools/testing/selftests/arm64/fp/README | 100 +++ .../testing/selftests/arm64/fp/asm-offsets.h | 11 + tools/testing/selftests/arm64/fp/assembler.h | 57 ++ .../testing/selftests/arm64/fp/fpsimd-stress | 60 ++ .../testing/selftests/arm64/fp/fpsimd-test.S | 482 +++++++++++++ .../selftests/arm64/fp/sve-probe-vls.c | 58 ++ .../selftests/arm64/fp/sve-ptrace-asm.S | 33 + tools/testing/selftests/arm64/fp/sve-ptrace.c | 336 +++++++++ tools/testing/selftests/arm64/fp/sve-stress | 59 ++ tools/testing/selftests/arm64/fp/sve-test.S | 672 ++++++++++++++++++ tools/testing/selftests/arm64/fp/vlset.c | 155 ++++ 14 files changed, 2046 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/arm64/fp/.gitignore create mode 100644 tools/testing/selftests/arm64/fp/Makefile create mode 100644 tools/testing/selftests/arm64/fp/README create mode 100644 tools/testing/selftests/arm64/fp/asm-offsets.h create mode 100644 tools/testing/selftests/arm64/fp/assembler.h create mode 100755 tools/testing/selftests/arm64/fp/fpsimd-stress create mode 100644 tools/testing/selftests/arm64/fp/fpsimd-test.S create mode 100644 tools/testing/selftests/arm64/fp/sve-probe-vls.c create mode 100644 tools/testing/selftests/arm64/fp/sve-ptrace-asm.S create mode 100644 tools/testing/selftests/arm64/fp/sve-ptrace.c create mode 100755 tools/testing/selftests/arm64/fp/sve-stress create mode 100644 tools/testing/selftests/arm64/fp/sve-test.S create mode 100644 tools/testing/selftests/arm64/fp/vlset.c -- 2.20.1

[PATCH v3 0/4] kselftests/arm64: add PAuth tests

by Boyan Karatotev

Pointer Authentication (PAuth) is a security feature introduced in ARMv8.3. It introduces instructions to sign addresses and later check for potential corruption using a second modifier value and one of a set of keys. The signature, in the form of the Pointer Authentication Code (PAC), is stored in some of the top unused bits of the virtual address (e.g. [54: 49] if TBID0 is enabled and TnSZ is set to use a 48 bit VA space). A set of controls are present to enable/disable groups of instructions (which use certain keys) for compatibility with libraries that do not utilize the feature. PAuth is used to verify the integrity of return addresses on the stack with less memory than the stack canary. This patchset adds kselftests to verify the kernel's configuration of the feature and its runtime behaviour. There are 7 tests which verify that: * an authentication failure leads to a SIGSEGV * the data/instruction instruction groups are enabled * the generic instructions are enabled * all 5 keys are different for a single thread * exec() changes all keys to new different ones * context switching preserves the 4 data/instruction keys * context switching preserves the generic keys The tests have been verified to work on qemu without a working PAUTH Implementation and on ARM's FVP with a full or partial PAuth implementation. Changes in v3: * remove double blank lines * Patch 1: "kselftests: add a basic arm64 Pointer Authentication test" * shorten pac_corruptor.S to cut out unnecessary code * add second signal handler to cover ARMv8.6 compatibily * Patch 3: "kselftests/arm64: add PAuth test for whether exec() changes keys" * change name of "exec_unique_keys" to "exec_changed_keys" * change reporting of error to be how many keys were left unchanged * Path 4: "kselftests/arm64: add PAuth tests for single threaded consistency and key uniqueness" * change unique to different * rename "single_thread_unique_keys" to "single_thread_different_keys" * change reporting of error to be how many keys were left unchanged Changes in v2: * remove extra lines at end of files * Patch 1: "kselftests: add a basic arm64 Pointer Authentication test" * add checks for a compatible compiler in Makefile * Patch 4: "kselftests: add PAuth tests for single threaded consistency and key uniqueness" * rephrase comment for clarity in pac.c Cc: Shuah Khan <shuah(a)kernel.org> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Will Deacon <will(a)kernel.org> Reviewed-by: Vincenzo Frascino <Vincenzo.Frascino(a)arm.com> Reviewed-by: Amit Daniel Kachhap <amit.kachhap(a)arm.com> Signed-off-by: Boyan Karatotev <boyan.karatotev(a)arm.com> Acked-by: Shuah Khan <skhan(a)linuxfoundation.org> Boyan Karatotev (4): kselftests/arm64: add a basic Pointer Authentication test kselftests/arm64: add nop checks for PAuth tests kselftests/arm64: add PAuth test for whether exec() changes keys kselftests/arm64: add PAuth tests for single threaded consistency and differently initialized keys tools/testing/selftests/arm64/Makefile | 2 +- .../testing/selftests/arm64/pauth/.gitignore | 2 + tools/testing/selftests/arm64/pauth/Makefile | 39 ++ .../selftests/arm64/pauth/exec_target.c | 34 ++ tools/testing/selftests/arm64/pauth/helper.c | 39 ++ tools/testing/selftests/arm64/pauth/helper.h | 28 ++ tools/testing/selftests/arm64/pauth/pac.c | 368 ++++++++++++++++++ .../selftests/arm64/pauth/pac_corruptor.S | 19 + 8 files changed, 530 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/arm64/pauth/.gitignore create mode 100644 tools/testing/selftests/arm64/pauth/Makefile create mode 100644 tools/testing/selftests/arm64/pauth/exec_target.c create mode 100644 tools/testing/selftests/arm64/pauth/helper.c create mode 100644 tools/testing/selftests/arm64/pauth/helper.h create mode 100644 tools/testing/selftests/arm64/pauth/pac.c create mode 100644 tools/testing/selftests/arm64/pauth/pac_corruptor.S -- 2.28.0

[PATCH] selftests/harness: Flush stdout before forking

by Michael Ellerman

The test harness forks() a child to run each test. Both the parent and the child print to stdout using libc functions. That can lead to duplicated (or more) output if the libc buffers are not flushed before forking. It's generally not seen when running programs directly, because stdout will usually be line buffered when it's pointing to a terminal. This was noticed when running the seccomp_bpf test, eg: $ ./seccomp_bpf | tee test.log $ grep -c "TAP version 13" test.log 2 But we only expect the TAP header to appear once. It can be exacerbated using stdbuf to increase the buffer size: $ stdbuf -o 1MB ./seccomp_bpf > test.log $ grep -c "TAP version 13" test.log 13 The fix is simple, we just flush stdout & stderr before fork. Usually stderr is unbuffered, but that can be changed, so flush it as well just to be safe.

[PATCH bpf-next v3 0/5] bpf: add MPTCP subflow support

by Nicolas Rybowski

Previously it was not possible to make a distinction between plain TCP sockets and MPTCP subflow sockets on the BPF_PROG_TYPE_SOCK_OPS hook. This patch series now enables a fine control of subflow sockets. In its current state, it allows to put different sockopt on each subflow from a same MPTCP connection (socket mark, TCP congestion algorithm, ...) using BPF programs. It should also be the basis of exposing MPTCP-specific fields through BPF. v2 -> v3: - minor modifications in new MPTCP selftests (Song). More details in patch notes. - rebase on latest bpf-next - the new is_mptcp field in bpf_tcp_sock is left as an __u32 to keep cohesion with the is_fullsock field from bpf_sock_ops.

[PATCH bpf-next v3 5/5] bpf: selftests: add bpf_mptcp_sock() verifier tests

by Nicolas Rybowski

This patch adds verifier side tests for the new bpf_mptcp_sock() helper. Here are the new tests : - NULL bpf_sock is correctly handled - We cannot access a field from bpf_mptcp_sock if the latter is NULL - We can access a field from bpf_mptcp_sock if the latter is not NULL - We cannot modify a field from bpf_mptcp_sock. Note that "token" is currently the only field in bpf_mptcp_sock. Currently, there is no easy way to test the token field since we cannot get back the mptcp_sock in userspace, this could be a future amelioration.
