--+QahgC5+KEYLbs62 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hey everyone, Problem: ptrace's PT_SETREGS request can't alter system calls. Code: http://alip.github.com/code/ptrace-freebsd-deny.c Expected: The file foo.bar shouldn't be created. Got: The file is created. Other efforts like replacing PT_GETREGS/PT_SETREGS calls with PT_KILL doesn't help, the file is created nevertheless. I'm inclined to call this a bug but I can't be sure. Any comments appreciated.
