[-- Attachment #1 --] 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. TIA -- Regards, Ali Polatel [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEABECAAYFAktSDREACgkQQU4yORhF8iAfoACgwQg6X/QZ9pKQ/mYm3zc152Wx 1h4AoJpuneWLGoFVs7cwRTjZPqUQfUzP =hZNV -----END PGP SIGNATURE-----
