Hello, guys I'm porting ltrace to FreeBSD and have one little question. ltrace uses non-standard PTRACE_SYSCALL request, which tells the kernel to stop traced process on every syscall entry and notify the parent. It makes us possible to trace child's syscalls and *catch execve/xfork events* and many more. BTW, that request is non-standard and FreeBSD doesn't support it. So, guys, what is a right way for a parent to catch child making syscall under FreeBSD? I have dosen k-mode solutions but how to do that from user-space? Thanks you very much!
