Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to various string and memory copy and set functions (as well as a few system calls and other miscellany) where known at function entry. RedHat has evidently built all "core system packages" with this option for some time. This option should be used at the top of Makefiles (or Makefile.inc where this is used for subdirectories) but after any setting of LIB. This is only useful for userland code, and cannot be used in libc or in any code which includes the libc internals, because it overrides certain libc functions with macros. Some effort has been made to make USE_FORT=yes work correctly for a full-system build by having the bsd.sys.mk logic disable the feature where it should not be used (libc, libssp iteself, the kernel) but no attempt has been made to build the entire system with USE_FORT and doing so will doubtless expose numerous bugs and misfeatures. Adjust the system build so that all programs and libraries that are setuid, directly handle network data (including serial comm data), perform authentication, or appear likely to have (or have a history of having) data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default, with the exception of libc, which cannot use USE_FORT and thus uses only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no per-directory or in a system build will disable if desired. 2007-05-28 16:06:17 +04:00			`USE_FORT?= yes # network client/server`

Make gcc 2.96 (and maybe earlier) happier. Include <stdlib.h>,<string.>, etc. as appropriate to get exit,srncmp,abs,abort,etc. Add -I${.CURDIR} to a few Makefiles 2000-07-03 06:51:12 +04:00			`CPPFLAGS+= -I${.CURDIR}`

.y.c <sys.mk> rule fixes. Don't create a y.tab.h file unless asked for, and use smarter creation of the header file. 1998-04-09 04:32:31 +04:00			`SRCS= docmd.c expand.c gram.y lookup.c main.c server.c`
