$NetBSD: TODO.ptrace,v 1.21 2017/02/14 18:38:07 kamil Exp $

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)
|
|
- remove 4.4BSD tracing with /proc, restrict /proc to Linux compat, to be
|
|
superseded with kevent tracing, the original purpose of /proc debugging is
|
|
long gone (performance issues with PT_WRITE_* and PT_READ_*)
|
|
- research kevent support for tracing a process over a file descriptor,
|
|
this means alternative to wait(2)-based events with passing events over the
|
|
kqueue API - signal handlers are global per application and they clash with
|
|
GUI toolkits (and perhaps other libraries) - this is long term wishlist in
|
|
GDB for Linux - the current approach is to fork and debug through GDB remote
|
|
protocol (this is how it is done in LLDB)
|
|
- 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
|
|
- research ipkdb(4)
|
|
|
|
and of course: fix as many bugs as possible.
|
|
|
|
Features in ELF, DWARF, CTF, DTrace are out of scope of the above list.
