NAME
tapset::kprocess - systemtap kernel process probe pointsDESCRIPTION
This family of probe points is used to probe the kernel's process activities. It contains the following probe points:
- kprocess.create
-
Fires whenever a new process is successfully created, either as a result of one of the fork syscall variants, or a new kernel thread.
Arguments:
task
a handle to the newly created processnew_pid
pid of the newly created process - kprocess.start
-
Fires immediately before a new process begins execution.
Arguments:
N/A
- kprocess.exec
-
Fires whenever a process attempts to exec to a new program
Arguments:
filename
the path to the new executable - kprocess.exec_complete
-
Fires at the completion of an exec call
Arguments:
errno
the error number resulting from the execsuccess
a boolean indicating whether the exec was successful - kprocess.exit
-
Fires when a process terminates. This will always be followed by a kprocess.release, though the latter may be delayed if the process waits in a zombie state.
Arguments:
code
the exit code of the process - kprocess.release
-
Fires when a process is released from the kernel. This always follows a kprocess.exit, though it may be delayed somewhat if the process waits in a zombie state.
Arguments:
task
a task handle to the process being releasedpid
pid of the process being released
