[Linux-kselftest-mirror] [PATCH 4.9 067/148] x86/selftests: Add clobbers for int80 on x86_64

by Greg Kroah-Hartman

4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dmitry Safonov <dsafonov(a)virtuozzo.com> [ Upstream commit 2a4d0c627f5374f365a873dea4e10ae0bb437680 ] Kernel erases R8..R11 registers prior returning to userspace from int80: https://lkml.org/lkml/2009/10/1/164 GCC can reuse these registers and doesn't expect them to change during syscall invocation. I met this kind of bug in CRIU once GCC 6.1 and CLANG stored local variables in those registers and the kernel zerofied them during syscall: https://github.com/xemul/criu/commit/990d33f1a1cdd17bca6c2eb059ab3be2564f7f… By that reason I suggest to add those registers to clobbers in selftests. Also, as noted by Andy - removed unneeded clobber for flags in INT $0x80 inline asm.

[Linux-kselftest-mirror] Difficulties for compilation without extra optimisation

by SF Markus Elfring

Hello, I came along some software modules where I suggested source code adjustments. Example: nfs/write: Use common error handling code in nfs_lock_and_join_requests() https://lkml.org/lkml/2017/11/7/599 https://patchwork.kernel.org/patch/10047013/ https://lkml.kernel.org/r/<7f072f78-eef4-6d87-d233-cee71dac5a32(a)users.sourceforge.net> I would like to check corresponding build results then without extra optimisation applied by the compiler. But I got surprised by error messages for a command like the following. elfring@Sonne:~/Projekte/Linux/next-patched> my_cc=/usr/bin/gcc-7 && LANG=C make -j4 CC="${my_cc}" HOSTCC="${my_cc}" EXTRA_CFLAGS='-O0' allmodconfig fs/nfs/write.o … In file included from ./include/linux/compiler.h:58:0, from ./include/uapi/linux/stddef.h:1, from ./include/linux/stddef.h:4, from ./include/uapi/linux/posix_types.h:4, from ./include/uapi/linux/types.h:13, from ./include/linux/types.h:5, from fs/nfs/write.c:9: ./arch/x86/include/asm/jump_label.h: In function ‘trace_nfs_writeback_page_enter’: ./include/linux/compiler-gcc.h:275:38: warning: asm operand 0 probably doesn’t match constraints #define asm_volatile_goto(x...) do { asm goto(x); asm (""); } while (0) … How do you think about to improve this software situation anyhow?

[Linux-kselftest-mirror] [PATCH 0/5] bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type

by Hendrik Brueckner

Perf tool bpf selftests revealed a broken uapi for s390 and arm64. With the BPF_PROG_TYPE_PERF_EVENT program type the bpf_perf_event structure exports the pt_regs structure for all architectures. This fails for s390 and arm64 because pt_regs are not part of the user api and kept in-kernel only. To mitigate the broken uapi, introduce a wrapper that exports pt_regs in an asm-generic way. For arm64, export the exising user_pt_regs structure. For s390, introduce a user_pt_regs structure that exports the beginning of pt_regs. Note that user_pt_regs must export from the beginning of pt_regs as BPF_PROG_TYPE_PERF_EVENT program type is not the only type for running BPF programs. Some more background: For the bpf_perf_event, there is a uapi definition that is passed to the BPF program. For other "probe" points like trace points, kprobes, and uprobes, there is no uapi and the BPF program is always passed pt_regs (which is OK as the BPF program runs in the kernel context). The perf tool can attach BPF programs to all of these "probe" points and, optionally, can create a BPF prologue to access particular arguments (passed as registers). For this, it uses DWARF/CFI information to obtain the register and calls a perf-arch backend function, regs_query_register_offset(). This function returns the index into (user_)pt_regs for a particular register. Then, perf creates a BPF prologue that accesses this register based on the passed stucture from the "probe" point. Part of this series, are also updates to the testing and bpf selftest to deal with asm-specifics. To complete the bpf support in perf, the the regs_query_register_offset function is added for s390 to support BPF prologue creation. Hendrik Brueckner (5): bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type s390/bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type arm64/bpf: correct broken uapi for BPF_PROG_TYPE_PERF_EVENT program type selftests/bpf: sync kernel headers and introduce arch support in Makefile perf s390: add regs_query_register_offset() arch/arm64/include/asm/perf_event.h | 2 + arch/arm64/include/uapi/asm/bpf_perf_event.h | 9 + arch/s390/include/asm/perf_event.h | 1 + arch/s390/include/asm/ptrace.h | 11 +- arch/s390/include/uapi/asm/bpf_perf_event.h | 9 + arch/s390/include/uapi/asm/ptrace.h | 11 + include/linux/perf_event.h | 6 +- include/uapi/asm-generic/bpf_perf_event.h | 9 + include/uapi/linux/bpf_perf_event.h | 5 +- kernel/events/core.c | 2 +- tools/arch/arm64/include/uapi/asm/bpf_perf_event.h | 9 + tools/arch/s390/include/uapi/asm/bpf_perf_event.h | 9 + tools/arch/s390/include/uapi/asm/ptrace.h | 471 +++++++++++++++++++++ tools/include/uapi/asm-generic/bpf_perf_event.h | 9 + tools/include/uapi/linux/bpf_perf_event.h | 6 +- tools/perf/arch/s390/Makefile | 1 + tools/perf/arch/s390/util/dwarf-regs.c | 32 +- tools/perf/check-headers.sh | 1 + tools/testing/selftests/bpf/Makefile | 14 +- 19 files changed, 602 insertions(+), 15 deletions(-) create mode 100644 arch/arm64/include/uapi/asm/bpf_perf_event.h create mode 100644 arch/s390/include/uapi/asm/bpf_perf_event.h create mode 100644 include/uapi/asm-generic/bpf_perf_event.h create mode 100644 tools/arch/arm64/include/uapi/asm/bpf_perf_event.h create mode 100644 tools/arch/s390/include/uapi/asm/bpf_perf_event.h create mode 100644 tools/arch/s390/include/uapi/asm/ptrace.h create mode 100644 tools/include/uapi/asm-generic/bpf_perf_event.h -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[Linux-kselftest-mirror] [PATCH AUTOSEL for 4.9 04/52] x86/selftests: Add clobbers for int80 on x86_64

by alexander.levin＠verizon.com

From: Dmitry Safonov <dsafonov(a)virtuozzo.com> [ Upstream commit 2a4d0c627f5374f365a873dea4e10ae0bb437680 ] Kernel erases R8..R11 registers prior returning to userspace from int80: https://lkml.org/lkml/2009/10/1/164 GCC can reuse these registers and doesn't expect them to change during syscall invocation. I met this kind of bug in CRIU once GCC 6.1 and CLANG stored local variables in those registers and the kernel zerofied them during syscall: https://github.com/xemul/criu/commit/990d33f1a1cdd17bca6c2eb059ab3be2564f7f… By that reason I suggest to add those registers to clobbers in selftests. Also, as noted by Andy - removed unneeded clobber for flags in INT $0x80 inline asm.
