Here is a patch that allows to open master ttys without giving full access to the process, at least for access to the ctty. It works by snooping the ctty pipe handles and duplicating them on the cygheap, for use by future opens in descendant processes. It passes all the tests I tried, but considering my lack of knowledge about ttys, everything is possible. Pierre 2003-09-29 Pierre Humblet <pierre.humblet@ieee.org> * cygheap.h (class cygheap_ctty): Create. (struct init_cygheap): Add inherited_ctty member. * cygheap.cc: Include pinfo.h. (cygheap_ctty::acquire): Create. (cygheap_ctty::pass): Ditto. (cygheap_ctty::close): Ditto. * fhandler_tty.cc (fhandler_tty_slave::open): Call cygheap->inherited_ctty.pass and cygheap->inherited_ctty.acquire. * tty.cc (tty::common_init): Remove call to SetKernelObjectSecurity and edit some comments. * syscalls.cc (setsid): Call cygheap->inherited_ctty.close.
