Most obvious shortcoming of the code is that it is i386-specific. I intended to split the patch in MI/MD parts similar to what native ptrace implementation is doing, but I haven't got a time for that yet. Not to mention the fact that I simply have no access to non-i386 FreeBSD boxes to test my changes. 2. There were some locking changes in -CURRENT and the code needs to be verified to follow the new rules. 3. PT_SYSCALL emulation is missing. It would be quite useful to use Linux's own strace utility to trace Linux binaries. I have semi-working version of that on my disk somewhere already. 4. The future KSE work will require serious rewrite of the ptrace(2) implementation anyway. On Mon, 13 May 2002 12:30:07 -0700 Marcel Moolenaar wrote: > > The PRs are assigned to Dag-Erling.
