o Allow use of fixed-length exponent on DSA signing
o Default fixed-window RSA, DSA, DH private-key operations
o More compilation issues fixed.
o Adaptation to more modern Kerberos API.
o Enhanced or corrected configuration for Solaris64, Mingw and Cygwin.
o Enhanced x86_64 assembler BIGNUM module.
o More constification.
o Added processing of proxy certificates (RFC 3820).

This should allow packages that purposely include <openssl/des_old.h> on
post-0.9.7 versions of OpenSSL to find it on NetBSD.
around at either build-time or at run-time is:
USE_TOOLS+= perl # build-time
USE_TOOLS+= perl:run # run-time
Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.
Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.
caches variable definitions that were computed by make. These variables
are specified by listing them in MAKE_VARS, e.g.,
.if !defined(FOO)
FOO!= very_time_consuming_command
.endif
MAKE_VARS+= FOO
bsd.pkg.mk will include only the one generated during the most recent
phase. A particular phase's makevars.mk file consists of variable
definitions that are a superset of all of the ones produced in previous
phases of the build.
The caching is useful because bsd.pkg.mk invokes make recursively,
which in the example above has the potential to run the very time-consuming
command each time unless we cause FOO to be defined for the sub-make
processes. We don't cache via MAKE_FLAGS because MAKE_FLAGS isn't
consistently applied to every invocation of make, and also because
MAKE_FLAGS can overflow the maximum length of a make variable very
quickly if we add many values to it.
One important and desirable property of variables cached via MAKE_VARS
is that they only apply to the current package, and not to any
dependencies whose builds may have been triggered by the current
package.
The makevars.mk files are generated by new targets fetch-vars,
extract-vars, patch-vars, etc., and these targets are built during
the corresponding real-* target to ensure that they are being invoked
with PKG_PHASE set to the proper value.
Also, remove the variables cache file that bsd.wrapper.mk was generating
since the new makevars.mk files provide the same functionality at a
higher level. Change all WRAPPER_VARS definitions that were used by
the old wrapper-phase cache file into MAKE_VARS definitions.
package because PKG_OPTION.<pkg> could contain negative options, which
are never part of PKG_OPTIONS. Instead, use the show-var target to
display the value. We cache it in WRAPPER_VARS and in MAKE_FLAGS to
prevent reinvoking the show-var target recursively.
Pkgsrc changes from version 0.9.7e include:
*) Install the man pages with names that are less likely to collide
with other packages' man pages.
*) Support PKG_OPTIONS of "idea", "mdc2" and "rc5" to allow building
with patented algorithms. By default, this package still builds
without patented algorithms.
Major changes from version 0.9.7e include:
*) Prompt for pass phrases when appropriate for PKCS12 input format.
*) Back-port of selected performance improvements from development
branch, as well as improved support for PowerPC platforms.
*) Add lots of checks for memory allocation failure, error codes to indicate
failure and freeing up memory if a failure occurs.
*) Add new -passin argument to dgst.
*) Make an explicit check during certificate validation to see that
the CA setting in each certificate on the chain is correct.
because:
- its behaviour changes between releases
- it uses build-host specific instructions where possible,

this breaks using the binary pkg when installed on systems with a
less capable processor. instead, just use -xO5 so the binary pkg will
work everywhere.

too numerous to be listed here, but include adding a new DES API
(support for the old one is still present).
Changes to the pkgsrc structure include:
* Install the shared libraries with a version number that matches the
OpenSSL version number
* Move some of the less often-used c_* utilities back into the examples
directory.
* Drop support for using the RSAREF library and always use the built-in
RSA code instead.
build shared libraries. on Darwin with xlc, this fails because of the
way xlc invokes Darwin's in-base libtool to create shared libraries,
meaning that the -all_load argument cannot be used to import all
symbols.
work around this the same way as UnixWare does it, by listing the
archive library contents and linking the object files into the shared
library individually. also remove some other assumed gcc'isms to make
this build on Darwin with xlc.
XXX maybe this pkg should be libtool'ized?
The idea is to prevent needing to patch source files for packages that
use OpenSSL for DES support by ensuring that including <openssl/des.h>
will always present the old DES API.
(1) If des_old.h exists, then we're using OpenSSL>=0.9.7, and
<openssl/des.h> already does the right thing.
(2) If des_old.h doesn't exist, then one of two things is happening:
(a) If <openssl/des.h> is old and (only) supports the old DES API,
then <openssl/des.h> does the right thing.
(b) If it's NetBSD's Special(TM) one that stripped out the old DES
support into a separate library and header (-ldes, <des.h>),
then we create a new header <openssl/des.h> that includes the
system one and <des.h>.
Also modify existing packages that set USE_OLD_DES_API to simply include
<openssl/des.h> instead of either <des.h> or <openssl/des_old.h> (This
step is mostly just removing unnecessary patches).
This should fix building packages that use OpenSSL's old DES API support
on non-NetBSD systems where the built-in OpenSSL is at least 0.9.7.
pkgsrc and in NetBSD-1.6.x) and OpenSSL 0.9.7 (in NetBSD-2.0), by
creating a new yes/no variable USE_OLD_DES_API that flags whether the
package wants to use the old DES API. If USE_OLD_DES_API is "yes",
then:
* For OpenSSL 0.9.6, symlink ${BUILDLINK_DIR}/include/openssl/des_old.h
to ${SSLBASE}/include/openssl/des.h.
* For NetBSD 2.0's "special" installation of OpenSSL 0.9.7, symlink
${BUILDLINK_DIR}/include/openssl/des_old.h to /usr/include/des.h,
and transform "-lcrypto" into "-ldes -lcrypto". This makes it
behave like stock OpenSSL 0.9.7 where the old DES functions are
part of libcrypto.
Software that wants to use the old DES API should be taught to do it
in a way that works with a stock installation of OpenSSL 0.9.7 -- by
including <openssl/des_old.h> and linking against "-lcrypto". Software
that wants to use the new DES API should simply depend on openssl>=0.9.7.
This change has no impact on existing packages as the new code is
active only when USE_OLD_DES_API == "yes".

usage of perl's int() causes trouble with perl 5.8.3 (5.8*?) on at least
NetBSD sparc64/1.6.2.
The perl script openssl-0.9.6m/crypto/bn/bn_prime.pl uses the perl
function int() to truncate the return of sqrt() function.
On the above mentioned platform this leads to execution error:
...
/usr/pkg/bin/perl bn_prime.pl >bn_prime.h
Illegal modulus zero at bn_prime.pl line 16.
Tracing the problem I've found that this int() usage may be the key
of the problem. Please note the following:
$ uname -srm; perl -v | grep 'This is perl'; perl -e 'print int(sqrt(3)),"\n"'
NetBSD 1.6.2 sparc64
This is perl, v5.8.3 built for sparc64-netbsd

And...
$ uname -srm; perl -v | grep 'This is perl'; perl -e 'print int(sqrt(3)),"\n"'
NetBSD 1.6.2 sparc64
This is perl, v5.6.1 built for sparc64-netbsd

Also note that perlfunc(3) warns about int() used for rounding and
recommends to use sprintf, printf, POSIX::floor or POSIX::ceil when
applicable.
My workaround is to use POSIX::floor() instead of int().
not defined yet until bsd.pkg.mk. Explicitly use "openssl" instead. This
correctly forces NetBSD installations of openssl to use /etc/openssl as
the configuration file directory as originally intended.

by moving the inclusion of buildlink3.mk files outside of the protected
region. This bug would be seen by users that have set PREFER_PKGSRC
or PREFER_NATIVE to non-default values.
BUILDLINK_PACKAGES should be ordered so that for any package in the
list, that package doesn't depend on any packages to the left of it
in the list. This ordering property is used to check for builtin
packages in the correct order. The problem was that including a
buildlink3.mk file for <pkg> correctly ensured that <pkg> was removed
from BUILDLINK_PACKAGES and appended to the end. However, since the
inclusion of any other buildlink3.mk files within that buildlink3.mk
was in a region that was protected against multiple inclusion, those
dependencies weren't also moved to the end of BUILDLINK_PACKAGES.
built-in or not into a separate builtin.mk file. The code to deal
checking for built-in software is much simpler to deal with in pkgsrc.
The buildlink3.mk file for a package will be of the usual format
regardless of the package, which makes it simpler for packagers to
update a package.
The builtin.mk file for a package must define a single yes/no variable
USE_BUILTIN.<pkg> that is used by bsd.buildlink3.mk to decide whether
to use the built-in software or to use the pkgsrc software.
According to README, "RSA Security holds software patents on the
RC5 algorithm. If you intend to use this cipher, you must contact
RSA Security for licensing conditions." And "The IDEA algorithm is
patented by Ascom ... They should be contacted if that algorithm
is to be used." The openssl FAQ says "For patent reasons, support
for IDEA, RC5 and MDC2 is disabled in this [Red Hat Linux] version."
The FAQ lists patent numbers and expiry dates of US patents:
MDC-2: 4,908,861 13/03/2007

[Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
*) Change RSA blinding code so that it works when the PRNG is not
seeded (in this case, the secret RSA exponent is abused as
an unpredictable seed -- if it is not unpredictable, there
is no point in blinding anyway). Make RSA blinding thread-safe
by remembering the creator's thread ID in rsa->blinding and
having all other threads use local one-time blinding factors
(this requires more computation than sharing rsa->blinding, but
avoids excessive locking; and if an RSA object is not shared
between threads, blinding will still be very fast).

place alternating values in each byte. This can be used to solve
two issues: 1) the removal of calls to memset() by highly optimizing

an operating system does not have a 'make' (ie only bmake), or if the OS
supplied 'make' is sufficiently broken (Irix), this will cause the build to

if build from this directory).
Patch Makefiles to use @MAKE@, which then, after patching, is substituted with
the actual ${MAKE} (can't use "MAKE= ${MAKE} -f Makefile.ssl").
