The code will be fixed for all known security vulnerabilities,
and a make.conf(5) knob (ENABLE_SUID_MAN) will be provided for
those who still want it installed setuid for whatever reasons.
The catpaging and setuidness features of man(1) combined make
it vulnerable to a number of security attacks. Specifically,
it was possible to overwrite system catpages with arbitrarily
contents by either setting up a symlink to a directory holding
system catpages, or by writing custom -mdoc or -man groff(1)
macro packages and setting up GROFF_TMAC_PATH in environment
to point to them. (See PR below for details).
This means man(1) can no longer create system catpages on a
regular user's behalf. (It is still able to if the user has
write permissions to the directory holding catpages, e.g.,
user's own manpages, or if the running user is ``root''.)
To create and install catpages during ``make world'', please
set MANBUILDCAT=YES in /etc/make.conf. To rebuild catpages
on a weekly basis, please set weekly_catman_enable="YES" in

Really irritating changes are the "forced" layering of malloc + friends
in order to use the GNU versions. Sorry, we have a *very* fine malloc,
and we will use it. Period. Even more irritating is that the GNU people
now want to replace ctype also!! So we partially dike it out here.
We now have to use the GCC stdarg.h varargs.h. We simply have no choice
as it has an internal representation that we really cannot properly define
in our headers.
This thing grew. We now have to link with many more files as if it
were one of the driver programs. We also have to deal with the very
irritating layering of malloc and friends. Our malloc works *very*
well thank you. Thus we will use it.

code in ipl.s and icu_ipl.s that used them was removed when the
interrupt thread system was committed. Debuggers also knew about
Xresume* because these labels hide the real names of the interrupt
handlers (Xintr*), and debuggers need to special-case interrupt
handlers to get the interrupt frame.
Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to
detect interrupt frames. Fast interrupt frames were never identified
correctly before, so this fixes the problem of the running stack
frame getting lost in a ddb or gdb trace generated from a fast
interrupt - e.g. when debugging a simple infinite loop in the kernel
using a serial console, the frame containing the loop would never
appear in a gdb or ddb trace.

1. To cross-build, one now needs to set TARGET_ARCH, and not the
MACHINE_ARCH. MACHINE_ARCH should never be changed manually!
2. Initialize DESTDIR= explicitly for bootstrap-tools, build-tools,
and cross-tools stages. This fixes broken header and library
dependencies problem. We build them in the host environment,
and obviously want them to depend on host headers and libraries.
The problem with broken header dependencies for bootstrap-tools
and cross-tools was already partially solved (see BOOTSTRAPPING
tests in bsd.prog.mk and bsd.lib.mk), but it was still there for
build-tools if the user ran "make world DESTDIR=/foo". Also,
for all of these stages, the library dependencies were broken
because of how bsd.libnames.mk define DPADD members.
We still provide a glue to install bootstrap- and cross-tools
under the ${WORLDTMP}.
Removed PATH overrides for bootstrap-, build-, and cross-tools
stages. There is just no reason why we would need to override
it, and the hacks to clean up the ${WORLDTMP} in the -DNOCLEAN
case are no longer needed with fixes from this step.
That is, we now never use ${WORLDTMP} headers and libraries,
and we don't use any ${WORLDTMP} installed binaries during
these stages. Again, these stages depend solely on the host
environment, including compiler, headers, and libraries.
3. Moved "miniperl" back from cross-tools (it has nothing to do
with a cross-compiler) to build-tools where it belongs. The
change from step 1 let to do this. Also, to make this work,
build-tools targets of "cc_tools" and "miniperl" were modified
to call "depend". Here follow the detailed explanations.
There are two categories of build tools, for now. In the first
category there are "cc_tools" and "miniperl". They occupy the
whole (sub)directory, and nothing needs to be done in this
subdirectory later during the "all" stage. They are also
constructed using system makefiles. We must build the .depend
early in the build-tools stage because:
1) They use (and depend on) the host environment.
2) If we don't do this in build-tools, the "depend" stage of
buildworld will do this for us; wrong library and header
dependencies will be recorded (DESTDIR=${WORLDTMP}) and,
what's worse, the "all" stage may then clobber the
build-architecture format tools (that we built in the
build-tools stage) with the target-architecture format
ones, breaking cross build.
In the second category there are all other build-tools. They
share their directory with the "main" module that needs them
in the "all" stage, and they don't show up themselves in the
.depend file. The portion of this fix was already committed
in gnu/usr.bin/cc/cc_tools/Makefile,v 1.52.
4. "libperl" is no longer a build tool, and "miniperl" is the
stand-alone application. I had to make this change because
build-tools and "all" stages share the same object directory.
Without this change, if we cross compile, libperl.a is first
built for the build architecture during the build-tools stage
(for the purposes of immediate linkage with "miniperl").
Later on, the "all" stage sees this library as up-to-date,
and doesn't rebuild it. The effect is that the wrong format
static libperl library is installed with installworld.
5. Fixed "includes" to install secure/lib/libtelnet headers if
required.

The version of the kernel has no bearing on what is in libc.
We now search for basename in libc to determin if we need to include
the libiberty version in the build.
This is all still a bit bogus as it will (like the sysctl method) cause
basename.o to be linked into the cross-build as well as the host build. It
would probably be better to test if we were doing the initial host build and
unconditionally include that. Once we've generated the target libc we know
that basename is available. (maybe test for $TOOLS_PREFIX or something).
