Stefan Liebler b08a6a0dea S390: Sync ptrace.h with kernel. [BZ #21539] ... This patch removes PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS as these requests does not exist on s390 kernel. But the kernel has support for PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND. Thus those are defined now. The current kernel s390 specific ptrace.h file also defines PTRACE_PEEKTEXT_AREA, PTRACE_PEEKDATA_AREA, PTRACE_POKETEXT_AREA, PTRACE_POKEDATA_AREA, PTRACE_PEEK_SYSTEM_CALL, PTRACE_POKE_SYSTEM_CALL and PTRACE_PROT, but those requests are not supported. Thus those defines are skipped in glibc ptrace.h. There were old includes of ptrace.h in sysdeps/s390/fpu/fesetenv.c. The ptrace feature isn't used there anymore, thus I removed the includes. Before this patch, <glibc>/sysdeps/unix/sysv/linux/s390/sys/ptrace.h uses ptrace-request 12 for PTRACE_GETREGS, but <kernel>/include/uapi/linux/ptrace.h uses 12 for PTRACE_SINGLEBLOCK. The s390 kernel has never had support for PTRACE_GETREGS! Thus glibc ptrace.h is adjusted to match kernel ptrace.h. The new s390 specific test ensures, that PTRACE_SINGLEBLOCK defined in glibc works as expected. If the kernel would interpret it as PTRACE_GETREGS, then the testcase will not make any progress and will time out. ChangeLog: [BZ #21539] * NEWS: Mention s390 ptrace request changes. * sysdeps/unix/sysv/linux/s390/sys/ptrace.h (PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS, PTRACE_SETFPREGS): Remove enum constant. (PT_GETREGS, PT_SETREGS, PT_GETFPREGS, T_SETFPREGS): Remove defines. (PTRACE_SINGLEBLOCK): New enum constant. (PT_STEPBLOCK): New define. (PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE, PTRACE_TE_ABORT_RAND): New enum constant and define. * sysdeps/s390/fpu/fesetenv.c: Remove ptrace.h includes. * sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c: New file. * sysdeps/unix/sysv/linux/s390/Makefile: Add test.		2017-06-19 16:27:25 +02:00
