OPENSSL_ia32cap is introduced to control recently added SSE2 code

link too. I'll be looking into it shortly...

This is very inefficient but it can be used to test some

Therefore, I've added a sanity checker.
Note that it can be combined with almost any other argument (the other

His comments are:
1) Changes all references for `True64' to be `Tru64', which is the correct
spelling for the OS name.
2) Makes `alpha-cc' be the same as `alpha164-cc', and adds an `alphaold-cc'
entry that is the same as the previous `alpha-cc'. The reason is that most
people these days are using the newer compiler, so it should be the default.
3) Adds a bit of commentary to Configure, regarding the name changes of
the OS over the years, so it's not so confusing to people that haven't been
with the OS for a while.
4) Adds an `alpha-cc-rpath' target (which is *not* selected automatically
by Configure under any circumstance) that builds an RPATH into the
shared libraries. This is explained in the comment in Configure. It's
very very useful for people that want it, and people that don't want it
just shouldn't choose that target.
5) Adds the `-pthread' flag as the best way to get POSIX thread support
from the newer compiler.
6) Updates the Makefile targets, so that when the `alpha164-cc', `alpha-cc',
or `alpha-cc-rpath' target is what Configure is set to use, it uses a Makefile
target that includes the `-msym' option when building the shared library.
This is a performance enhancement.
7) Updates `config' so that if it detects you're running version 4 or 5
of the OS, it automatically selects `alpha-cc', but uses `alphaold-cc'
for versions 1-3 of the OS.
8) Updates the comment in opensslv.h, fixing both the OS name typo and
adding a reference to IRIX 6.x, since the shared library semantics are
virtually identical there.

SSL according to RFC 2712. His comment is:
This is a patch to openssl-SNAP-20010702 to support Kerberized SSL
authentication. I'm expecting to have the full kssl-0.5 kit up on
sourceforge by the end of the week. The full kit includes patches
for mod-ssl, apache, and a few text clients. The sourceforge URL
is http://sourceforge.net/projects/kssl/ .
Thanks to a note from Simon Wilkinson I've replaced my KRB5 AP_REQ
message with a real KerberosWrapper struct. I think this is fully
RFC 2712 compliant now, including support for the optional
authenticator field. I also added openssl-style ASN.1 macros for
a few Kerberos structs; see crypto/krb5/ if you're interested.
variables and disable the Alpha assembler for now, since it has been
shown to fail.
The Alpha failure can be shown by adding the following numbers:
FFFFFFFFFFFFFF0000FF2E00000000EBFFFFFF0000D1
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF46FFE0FFFF0000
The result is:
1FFFFFFFFFFFEFF0000FF2E0000000032FFE0FEFF00D1
The result should really be:
1FFFFFFFFFFFFFF0000FF2E0000000032FFE0FEFF00D1
functions on platform were that's the best way to handle exporting
global variables in shared libraries. To enable this functionality,
one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
"OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
is normally done by Configure or something similar).
To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
in the source file (foo.c) like this:
OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
OPENSSL_IMPLEMENT_GLOBAL(double,bar);
To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
OPENSSL_DECLARE_GLOBAL(int,foo);
#define foo OPENSSL_GLOBAL_REF(foo)
OPENSSL_DECLARE_GLOBAL(double,bar);
#define bar OPENSSL_GLOBAL_REF(bar)
The #defines are very important, and therefore so is including the
header file everywere where the defined globals are used.
The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
of ASN.1 items, but that structure is a bt different.
The largest change is in util/mkdef.pl which has been enhanced with
better and easier to understand logic to choose which symbols should
go into the Windows .def files as well as a number of fixes and code
cleanup (among others, algorithm keywords are now sorted
lexicographically to avoid constant rewrites).
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.
I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.
you should defined _THREAD_SAFE (I found that in an include file, and
that's what everybody tells me) or _THREADSAFE (that's what the gcc
manual says in the FreeBSD-specific section), so I defined both, just
to be safe.
to have the full extension information, so residual shared libraries
can be removed so the applications and test programs do not get linked
against them by mistake...
- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.
- Make as few rebuilds of the shared libraries as possible.
- Still avoid linking the OpenSSL programs with the shared libraries.
- When installing, install the shared libraries separately from the
static ones.
The old code was painfully primitive and couldn't handle
distinct certificates using the same subject name.
The new code performs several tests on a candidate issuer
certificate based on certificate extensions.
It also adds several callbacks to X509_VERIFY_CTX so its
behaviour can be customised.
Unfortunately some hackery was needed to persuade X509_STORE
to tolerate this. This should go away when X509_STORE is
replaced, sometime...
This must have broken something though :-(
there's support for building under Linux and True64 (using examples
from the programming manuals), including versioning that is currently
the same as OpenSSL versions but should really be a different series.
With this change, it's up to the users to decide if they want shared
libraries as well as the static ones. This decision now has to be
done at configuration time (well, not really, those who know what they
do can still do it the same way as before).
The OpenSSL programs (openssl and the test programs) are currently
always linked statically, but this may change in the future in a
configurable manner. The necessary makefile variables to enable this
are in place.
Also note that I have done absolutely nothing about the Windows target
to get something similar. On the other hand, DLLs are already the
default there, but without versioning, and I've no idea what the
possibilities for such a thing are there...

* Added the dso_scheme config string entry for OpenBSD-x86 to give it
DSO support.
* 'make update' that has also absorbed some of Steve's mkstack changes
for the ASN-related macros.
Also, "make update" has added some missing functions to libeay.num,
updated the TABLE for the alpha changes, and updated thousands of
dependancies that have changed from recent commits.
structures and functions for each stack type. The previous behaviour
can be enabled by configuring with the "-DDEBUG_SAFESTACK" option.
This will also cause "make update" (mkdef.pl in particular) to
update the libeay.num and ssleay.num symbol tables with the number of
extra functions DEBUG_SAFESTACK creates.
The way this change works is to accompany each DECLARE_STACK_OF()
macro with a set of "#define"d versions of the sk_##type##_***
functions that ensures all the existing "type-safe" stack calls are
precompiled into the underlying stack calls. The presence or abscence
of the DEBUG_SAFESTACK symbol controls whether this block of
"#define"s or the DECLARE_STACK_OF() macro is taking effect. The
block of "#define"s is in turn generated and maintained by a perl
script (util/mkstack.pl) that encompasses the block with delimiting
C comments. This works in a similar way to the auto-generated error
codes and, like the other such maintenance utilities, is invoked
by the "make update" target.
A long (but mundane) commit will follow this with the results of
"make update" - this will include all the "#define" blocks for
each DECLARE_STACK_OF() statement, along with stripped down
libeay.num and ssleay.num files.

variety of platforms. A few are missing, and they will be added in
eventually, but as this is new stuff, it was better to not break lots of
platforms in one go that we can't easily test. The changes to "Configure"
should illustrate how to add support to other systems if you feel like
having a go.
NB: I'll add something shortly to allow you to add "dlfcn.h" support on
those platforms that don't have (or need) a dlfcn.h header file. (The
symbol for Configure will probably by "dlfcn_no_h").
