NAME
tapset::signal - systemtap signal tapset DESCRIPTION This family of probe points is used to probe signal activities. Since there are so many signals sent to processes at any given point, it is advisable to filter the information according to the requirements. For example, filter only for a particular signal (if sig==2) or for a particular process (if pidname==stap). signal.send Signal being sent to a process See probe::signal.send(3stap) for details. signal.send.return Signal being sent to a process completed (deprecated in SystemTap 2.1) See probe::signal.send.return(3stap) for details. signal.checkperm Check being performed on a sent signal See probe::signal.checkperm(3stap) for details. signal.checkperm.return Check performed on a sent signal completed See probe::signal.checkperm.return(3stap) for details. signal.wakeup Sleeping process being wakened for signal See probe::signal.wakeup(3stap) for details. signal.checkignored Checking to see signal is ignored See probe::signal.checkignored(3stap) for details. signal.checkignored.return Check to see signal is ignored completed See probe::signal.checkignored.return(3stap) for details. signal.forcesegv Forcing send of SIGSEGV See probe::signal.forcesegv(3stap) for details. signal.forcesegv.return Forcing send of SIGSEGV complete See probe::signal.forcesegv.return(3stap) for details. signal.syskill Sending kill signal to a process See probe::signal.syskill(3stap) for details. signal.syskill.return Sending kill signal completed See probe::signal.syskill.return(3stap) for details. signal.systkill Sending a kill signal to a thread See probe::signal.systkill(3stap) for details. signal.systkill.return Sending kill signal to a thread completed See probe::signal.systkill.return(3stap) for details. signal.systgkill Sending kill signal to a thread group See probe::signal.systgkill(3stap) for details. signal.systgkill.return Sending kill signal to a thread group completed See probe::signal.systgkill.return(3stap) for details. signal.sendsigqueue Queuing a signal to a process See probe::signal.sendsigqueue(3stap) for details. signal.sendsigqueue.return Queuing a signal to a process completed See probe::signal.sendsigqueue.return(3stap) for details. signal.pending Examining pending signal See probe::signal.pending(3stap) for details. signal.pending.return Examination of pending signal completed See probe::signal.pending.return(3stap) for details. signal.handle Signal handler being invoked See probe::signal.handle(3stap) for details. signal.handle.return Signal handler invocation completed See probe::signal.handle.return(3stap) for details. signal.doaction Examining or changing a signal action See probe::signal.doaction(3stap) for details. signal.doaction.return Examining or changing a signal action completed See probe::signal.doaction.return(3stap) for details. signal.procmask Examining or changing blocked signals See probe::signal.procmask(3stap) for details. signal.procmask.return Examining or changing blocked signals completed See probe::signal.procmask.return(3stap) for details. signal.flush Flushing all pending signals for a task See probe::signal.flush(3stap) for details. getsaflags Returns the numeric value of saflags See function::getsaflags(3stap) for details. getsahandler Returns the numeric value of sahandler See function::getsahandler(3stap) for details. sigsetmaskstr Returns the string representation of a sigset See function::sigsetmaskstr(3stap) for details. issigblocked Returns 1 if the signal is currently blocked, or 0 if it is not See function::issigblocked(3stap) for details. saflagsstr Returns the string representation of saflags See function::saflagsstr(3stap) for details. sahandler Returns the string representation of an sahandler See function::sahandler(3stap) for details. signalstr Returns the string representation of a signal number See function::signalstr(3stap) for details.
