NAME
stapprobes.kprocess - systemtap kernel process probe points
DESCRIPTION
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 process
- new_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 exec
- success
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 released
- pid
pid of the process being released
