Items we (currently) plan to finish in the ptrace(2) field:
- verify ppid of core dump generated with PT_DUMPCORE
it must point to the real parent, not tracer
- adapt OpenBSD regress test (regress/sys/ptrace/ptrace.c) for the ATF context
- reiterate over FreeBSD tests and add missing ones if applicable
- add new ptrace(2) calls to lock (suspend) and unlock LWP within a process
- add PT_DUMPCORE tests in the ATF framework
- add ATF tests for PT_WRITE_I and PIOD_WRITE_I - test mprotect restrictions
- switch PT_WATCHPOINT* to PT_*ETDBREGS and document it, add ATF tests
- add tests for the procfs interface covering all functions available on the
same level as ptrace(2)
- add support to read debugger events via a file descriptor in procfs
(kevent(2)), it's still useful in cases when a parent traces tracee and has
to call waitpid(2) for its child - as this clashes with GUI toolkits
- add support for PT_STEP, PT_GETREGS, PT_SETREGS, PT_GETFPREGS, PT_SETFPREGS
in all ports
- add proper implementation of PTRACE_VFORK for vfork(2)-like events
- add ATF tests for SIGCHLD
- add si_code values for PT_SYSCALL: TRAP_SCE and TRAP_SCX
- add ATF tests for PT_SYSCALL and PT_SYSCALLEMU
- research support PT_SYSCALL & PT_STEP combined like in Linux
- fix more calls for netbsd32 compat
and of course: fix as many bugs as possible.
Features in ELF, DWARF, CTF, DTrace are out of scope of the above list.
