* fhandler.h (fhandler_tty_slave::fch_open_handles): Declare private. (fhandler_tty_slave::fch_close_handles): Ditto. (fhandler_tty_slave::cygserver_attach_tty): Drop declaration. (fhandler_tty_slave::fstat): Declare public. (fhandler_tty_slave::fchmod): Declare public. (fhandler_tty_slave::fchown): Declare public. (class fhandler_pty_master): Add master_ctl handle. (fhandler_pty_master::pty_master_thread): Declare public. * fhandler_termios.cc (fhandler_termios::tcinit): If the process is started from a non-Cygwin process, make it tty process group leader. * fhandler_tty.cc: Throughout accommodate additional security related arguments in calls to functions creating or opening objects. (close_maybe): Move to start of file to reuse it in other methods. (struct pipe_request): Define. (struct pipe_reply): Define. (fhandler_tty_slave::open): Throughout, try to open synchronization objects with MAXIMUM_ALLOWED permissions. Drop call to cygserver. Try to duplicate pipe handles via master_ctl pipe if duplicating directly doesn't work. (fhandler_tty_slave::cygserver_attach_tty): Remove. (fhandler_tty_slave::init): Close unused incoming pipe handle. (fhandler_pty_master::close): Send exit message to master control thread and close master_ctl handle. (fhandler_pty_master::pty_master_thread): New method, implementing the master control thread. (pty_master_thread): Static helper to start master control thread. (fhandler_pty_master::setup): Simplify creating pipe inheritance. Make sure we're the one creating the input_available_event. Add comment to explain why. Create master_ctl pipe and start master control thread. Close master_ctl handle in case of error. * security.cc (alloc_sd): Add code to handle tty objects. Add comments to explain what exactly is required. (get_object_sd): New function. (get_object_attribute): New function. (create_object_sd_from_attribute): New function. (set_object_sd): New function.

(get_object_attribute): Declare. (create_object_sd_from_attribute): Declare. (set_object_sd): Declare. (set_object_attribute): Declare. * tty.cc (tty::slave_alive): Implement directly instead of via alive. (tty::exists): Open mutex handle with READ_CONTROL access. (tty::alive): Remove. (tty::open_output_mutex): Convert to inline method. (tty::open_input_mutex): Ditto. (tty::open_mutex): Take additional ACCESS_MASK parameter for the mutex open access mask. (tty::open_inuse): New method. (tty::create_inuse): Take PSECURITY_ATTRIBUTES parameter. Drop fmt name parameter. Always create TTY_SLAVE_ALIVE event. (tty::get_event): Take additional PSECURITY_ATTRIBUTES parameter for CreateEvent. * tty.h (class tty): Change declarations according to aforementioned changes. (tty::open_output_mutex): Implement as inline method. (tty::open_input_mutex): Ditto.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
