through the use of a new build directive, MACHINE_CPU, which contains a
list of the CPU generations/features for which optimizations are desired.
This feature will be extended to cover the ports tree in the future.
Currently OpenSSL provides optimizations for i386, i586 and i686-class
CPUs. Currently it has not been tested on an i386 or i486.
Teach make(1) to provide sensible defaults for MACHINE_CPU if it is not
defined (namely, the lowest common denominator CPU we support for each
architecture). Currently this is i386 for the i386 architecture and ev4
for the alpha. sys.mk also sets the variable as a last resort for
consistency with MACHINE_ARCH and bootstrapping from very old versions of
make.
Benchmarks show a significant speed increase even in the i386 case, with
additional improvements for i586 and i686 systems. For maximum performance
define MACHINE_CPU=i686 i586 i386 in /etc/make.conf.

revision 1.25. When evaluating the termination condition for the
iteration over all map entries, we must take care to use the kernel
versions of all pointers. The code was comparing a kernel pointer
to a pointer within a local variable, so the loop never terminated.
16 characters, only check the first 16 since that is all the kernel

Otherwise, "killall communicator-linux-4.76.bin" will not match

o In practice: the comment indicates that all but umask and

in practice, the uid, gids, resources, and priority were set, and
then resources and priority were selectively removed. This meant
that some aspects of the user context were not set, including handling
of login events (wtmp, utmp), as well as the path specified in
login.conf.
o I changed it so that the behavior is the same, but instead,
LOGIN_SETALL is used, and appropriate flags are removed, including

o This has the practical benefit that as new LOGIN_SET* flags are

For example, of a LOGIN_SETLABEL flag is introduced to support
MAC labels determined by the user's login class, then su no longer
