Hello. utrace patches for 3.1 kernel. Untested, will try to do some tests tomorrow. I do not want to spam you all and the lists, please look at git://git.kernel.org/pub/scm/linux/kernel/git/oleg/misc.git utrace-3.1 Oleg Nesterov (29): utrace: add utrace_init_task/utrace_free_task calls tracehooks: add utrace hooks tracehooks: reintroduce tracehook_consider_fatal_signal() add utrace hooks into sig_ignored() and recalc_sigpending() restore the EXEC/EXIT/CLONE utrace hooks utrace: utrace_report_death() can use task_utrace_struct() restore the DEATH/REAP utrace hooks utrace: remove jobctl bits ptrace: take ->siglock around s/TRACED/RUNNING/ introduce wake_up_quiescent() introduce ptrace_signal_wake_up() wait_task_inactive: treat task->state and match_state as bitmasks introduce TASK_UTRACED state utrace: use TASK_UTRACED instead of TASK_TRACED reintroduce tracehook_finish_jctl() as utrace_end_stop() teach wake_up_quiescent() to do "selective" wake_up ptrace_stop: do not assume the task is running after wake_up_quiescent() get_signal_to_deliver: restore/restructure utrace/ptrace signal reporting utrace_get_signal: s/JOBCTL_STOP_PENDING/JOBCTL_PENDING_MASK/ introduce ptrace_set_syscall_trace() introduce PT_SYSCALL_TRACE flag utrace: don't clear TIF_SYSCALL_TRACE if it is needed by ptrace introduce task_utrace_lock/task_utrace_unlock teach ptrace_set_syscall_trace() to play well with utrace introduce PT_SINGLE_STEP and PT_SINGLE_BLOCK utrace: finish_resume_report: don't do user_xxx_step() if ptrace_wants_step() ptrace: shift user_*_step() from ptrace_resume() to ptrace_stop() ptrace_disable: no need to disable stepping ptrace_report_syscall: check TIF_SYSCALL_EMU Roland McGrath (1): utrace core Documentation/DocBook/Makefile | 2 +- Documentation/DocBook/utrace.tmpl | 589 +++++++++ arch/s390/kernel/traps.c | 4 +- arch/x86/kernel/ptrace.c | 1 - fs/exec.c | 5 +- fs/proc/array.c | 14 +- include/linux/ptrace.h | 7 + include/linux/sched.h | 25 +- include/linux/signal.h | 2 + include/linux/tracehook.h | 53 +- include/linux/utrace.h | 773 ++++++++++++ init/Kconfig | 9 + kernel/Makefile | 1 + kernel/exit.c | 5 + kernel/fork.c | 9 + kernel/ptrace.c | 57 +- kernel/sched.c | 2 +- kernel/signal.c | 97 ++- kernel/utrace.c | 2461 +++++++++++++++++++++++++++++++++++++ 19 files changed, 4062 insertions(+), 54 deletions(-) create mode 100644 Documentation/DocBook/utrace.tmpl create mode 100644 include/linux/utrace.h create mode 100644 kernel/utrace.c _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
