Module libafl_bolts::os::unix_signals

Signal handling for unix

Structs

• siginfo_t
• ucontext_t

Enums

• Signal
  All signals on this system, as enum.
• c_void
  Equivalent to C’s void type when used as a pointer.

Constants

• CTRL_C_EXIT
  The special exit code when the target exited through ctrl-c

Traits

• Handler
  A trait for LibAFL signal handling

Functions

• setup_signal_handler^⚠
  Setup signal handlers in a somewhat rusty way. This will allocate a signal stack and set the signal handlers accordingly. It is, for example, used in LibAFL's InProcessExecutor to restart the fuzzer in case of a crash, or to handle SIGINT in the broker process.
• ucontext
  Function to get the current ucontext_t for this process. This calls the libc getcontext function under the hood. It can be useful, for example for dump_regs. Note that calling this method may, of course, alter the state. We wrap it here, as it seems to be (currently) not available on MacOS in the libc crate.
