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 pid_name==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.check_ignored
Checking to see signal is ignored
See probe::signal.check_ignored(3stap)
for details.
signal.check_ignored.return
Check to see signal is ignored completed
See probe::signal.check_ignored.return(3stap)
for details.
signal.force_segv
Forcing send of SIGSEGV
See probe::signal.force_segv(3stap)
for details.
signal.force_segv.return
Forcing send of SIGSEGV complete
See probe::signal.force_segv.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.sys_tkill
Sending a kill signal to a thread
See probe::signal.sys_tkill(3stap)
for details.
signal.systkill.return
Sending kill signal to a thread completed
See probe::signal.systkill.return(3stap)
for details.
signal.sys_tgkill
Sending kill signal to a thread group
See probe::signal.sys_tgkill(3stap)
for details.
signal.sys_tgkill.return
Sending kill signal to a thread group completed
See probe::signal.sys_tgkill.return(3stap)
for details.
signal.send_sig_queue
Queuing a signal to a process
See probe::signal.send_sig_queue(3stap)
for details.
signal.send_sig_queue.return
Queuing a signal to a process completed
See probe::signal.send_sig_queue.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.do_action
Examining or changing a signal action
See probe::signal.do_action(3stap)
for details.
signal.do_action.return
Examining or changing a signal action completed
See probe::signal.do_action.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
