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. |

# $NetBSD: README,v 1.13 2005/03/01 13:19:51 wiz Exp $ # Original from FreeBSD, no rcs id. This is the pkg_install suite of tools for doing maintainance of software "packages". More documentation is available in the man pages for each individual command. This code was written by Jordan Hubbard for FreeBSD, snatched and mildly reshaped by John Kohl in NetBSD and the changes taken back into FreeBSD again by Jordan, who then proceeded to add another couple of dozen features on top. Whee! :-) In another round of enhancements, NetBSD changes were added by Alistair Crooks, Hubert Feyrer, Thorsten Frueauf, Rene Hexel, Christian E. Hopps, Thomas Klausner, Johnny Lam, and Matthias Scheler. When making snapshots, please modify PKGTOOLS_VERSION in lib/version.h to that day's date. src/usr.sbin/pkg_install is the canonical location for these sources. Any changes should be made here first, then merged over to pkgsrc.
