Summary of this long ChangeLog:
* Splitted `libgtop_sysdeps.la' into `libgtop_sysdeps.la' and `libgtop_sysdeps_suid.la'. Everything that needs to be suid/sgid is in `libgtop_sysdeps_suid.la' and the rest in `libgtop_sysdeps.la'. The functions from `libgtop_sysdeps_suid.la' have the `_p' prefix and the ones from `libgtop_sysdeps.la' the `_s' prefix. The suid library uses `glibtop_open_p' and `glibtop_close_p', the normal one `glibtop_init_s' (found in lib/init.c), `glibtop_open_s' and `glibtop_close_s'. * Added `libgtop_suid_common.la' containing stuff from sysdeps/common that is required from the suid server (currently everything from error.c and xmalloc.c). This means, we can add some more stuff to `libgtop_common.la' without the risk that it may be dangerous in the suid server. * The ``library order'' is much clearer now: -> `libgtop.la' (from lib/) contains user-level stuff; all functions except `glibtop_init_r' have the `_l' suffix. -> `libgtop_common.la' (from sysdeps/common/) contains stuff that is common among the sysdeps directories. use anything from `libgtop_sysdeps.la' and `libgtop_sysdeps_suid.la'. -> `libgtop_sysdeps.la' (from sysdeps/<sysdeps_dir>/) contains everything from the sysdeps directory that doesn't need to be suid/sgid. -> `libgtop_suid_common.la' (from sysdeps/common/) is used from the suid server instead of `libgtop_common.la'. -> `libgtop_sysdeps_suid.la' (from sysdeps/<sysdeps_dir>/) contains everything from the sysdeps directory that needs to be in the suid server. * To summarize: the server is linked only with functions that need to be suid and everything else is linked only with functions that do not need to be suid. Martin 1998-07-22 Martin Baulig <martin@home-of-linux.org> * lib/init.c (glibtop_init_s): Added this init function of the sysdeps directory `libgtop_sysdeps.la'. * lib/open.c (glibtop_open_l): Unconditionally calling `glibtop_init_s' after server initialization. * lib/lib.awk: Removed references to functions from `libgtop_sysdeps_suid.la' to avoid undefined symbols. * sysdeps/stub/open.c (glibtop_open_s): Renamed this function from `glibtop_open_r'. * sysdeps/stub/close.c (glibtop_close_s): Renamed this function from `glibtop_close_l'. * sysdeps/kernel/open.c (glibtop_open_s): Renamed this function from `glibtop_open_r'. * sysdeps/kernel/close.c (glibtop_close_s): Renamed this function from `glibtop_close_l'. * sysdeps/linux/open.c (glibtop_open_s): Renamed this function from `glibtop_open_r'. * sysdeps/linux/close.c (glibtop_close_s): Renamed this function from `glibtop_close_l'. * sysdeps/osf1/Makefile.am (lib_LTLIBRARIES): Added `libgtop_sysdeps_suid.la' for the suid server. * sysdeps/osf1/open_suid.c (glibtop_open_p): New file. Contains all stuff that was formerly in `open.c'. * sysdeps/osf1/open.c: Moved everything from here into the new file `open_suid.c'. * sysdeps/osf1/open.c (glibtop_open_s): New function. * sysdeps/osf1/close_suid.c (glibtop_close_p): New file. * sysdeps/osf1/close.c (glibtop_close_s): New function. * sysdeps/osf1/*.c: Using the new init, open and close functions. * sysdeps/sun4/Makefile.am (lib_LTLIBRARIES): Added `libgtop_sysdeps_suid.la' for the suid server. * sysdeps/sun4/nosuid.c (glibtop_open_s, glibtop_close_s): New file * sysdeps/sun4/*.c: All functions now have the `_p' suffix. * sysdeps/common/Makefile.am (lib_LTLIBRARIES): Added `libgtop_suid_common.la' which only contains stuff that is needed in the suid parts. * sysdeps/common/xmalloc.c: Using `glibtop_error_io_r' instead of `glibtop_error_r'. * sysdeps/{kernel, linux, osf1, sun4, stub}/init.c: Removed. `glibtop_init_s' has been moved into `lib/init.c' since it's the same in all the sysdeps directories. * src/server/main.c: It is now an error to request a feature that does not need the suid server. * src/proxy: Removed.
