tapset::kprocess − systemtap kernel process probe points
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
