process_execute_failed

Intro

process_execute_failed - a failed process execution occurred.

Description

An event marking that a process execution failure has occurred. This event helps in monitoring failed executions, with the ability to access (mostly - see below) kernel provided arguments. This is a high-level event, planned to include all the failure cases of process execution, while providing as much as possible the arguments as used by the kernel.

Arguments

  • path:const char*[K] - the path to the file as provided by the user.
  • binary.path:const char*[K] - the binary path being executed.
  • binary.device_id:dev_t[K] - the device id of the binary being executed.
  • binary.inode_number:unsigned long[K] - the inode number of the binary being executed.
  • binary.ctime:unsigned long[K] - the change time (ctime) of the binary being executed.
  • binary.inode_mode:u64[K] - the inode mode of the binary being executed.
  • interpreter_path:const char*[K] - the path to the interpreter used.
  • stdin_type:umode_t[K] - the stdin type.
  • stdin_path:char*[K] - the stdin path.
  • kernel_invoked:int[K] - whether this execution was initiated by the kernel (or user-space).
  • environment:const char*const*[U,TOCTOU] - the environment variables of this execution.
  • arguments:const char*const*[U,TOCTOU] - the arguments of this execution.

Hooks

exec_binprm

Type

kprobe

Purpose

Fetch the arguments of exec_binprm

exec_binprm

Type

kretprobe

Purpose

Fetch the return value of exec_binprm

Example Use Case

./tracee -e process_execution_failed

Issues

Currently, only covers failed executions that are happening within exec_binprm. Other failures may occur at an earlier stage.
