| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge from setuid-branch. Changes also by Martin Hunt <hunt@redhat.com>. * control.c (_stp_ctl_write): Make sure we don't overflow. (_stp_ctl_open_cmd): Do not allow multiple opens of the control file. (_stp_ctl_write_cmd): Once STP_START is received, ignore everything except STP_EXIT. Create another state variable "initialized". Don't respond to STP_SYMBOLS or STP_MODULES unless initialized is 0.
