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 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
|
|
- remove exect(3) from libc - there is no usecase for it
|
|
- research what happens when a tracee masks signals (including SIGTRAP) and a
|
|
breakpoint is triggered
|
|
- 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
|
|
- add PT_SET_SIGMASK and PT_GET_SIGMASK - used by checkpointing software
|
|
|
|
and of course: fix as many bugs as possible.
|
|
|
|
Features in ELF, DWARF, CTF, DTrace are out of scope of the above list.
