Otherwise I see output like | Dumping path for 1536412160 fd via self 27 [/usr/bin/screen] where fd is taken from stack and what is worse -- we work with root privilegues, thus dumping _anything_ from stack is very bad idea. With explicitly cleared stack data and FD_DESC_INVALID the log file will have an entry like | Dumping path for -3 fd via self 27 [/usr/bin/screen] Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
