Also, change ssl_create_cipher_list() so that it no longer

This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just

In some cases the ciphersuite list generated from a given string is

more "strain" on the current BN_CTX implementation (which has a fixed limit
to the number of variables it will hold), but so far this limit is not

This also changes the default RSA implementation code to use the BN_CTX in

linux system (namely mine) chokes on our definitions and uses of the "HZ"
symbol in crypto/tmdiff.[ch] and apps/speed.c as a "bad function cast"
(when in fact there is no function casting involved at all). In both cases,
it is easily worked around by not defining a cast into the macro and
jiggling the expressions slightly.
In addition - this highlights some cruft in openssl that needs sorting out.
The tmdiff.h header is exported as part of the openssl API despite the fact
that it is ugly as the driven sludge and not used anywhere in the library,
applications, or utilities. More weird still, almost identical code exists
in apps/speed.c though it looks to be slightly tweaked - so either tmdiff
should be updated and used by speed.c, or it should be dumped because it's
obviously not useful enough.
Rather than removing it for now, I've changed the API for tmdiff to at
least make sense. This involves taking the object type (MS_TM) from the
implementation and using it in the header rather than using "char *" in the
API and casting mercilessly in the code (ugh). If someone doesn't like
"MS_TM" and the "ms_time_***" naming, by all means change it. This should
be a harmless improvement, because the existing API is clearly not very
useful (eg. we reimplement it rather than using it in our own utils).
However, someone still needs to take a hack at consolidating speed.c and
tmdiff.[ch] somehow.

these lower-level handlers, it becomes impossible to do a fallback to

This change allows the default DSA_METHOD to function in such circumstances
by only using dsa_mod_exp() and bn_mod_exp() handlers if they exist,
otherwise using BIGNUM implementations directly (which is what those
handlers did before this change). There should be no noticable difference
for the software case, or indeed any custom case that didn't already

key-generation and prime-checking functions. Rather than explicitly passing
callback functions and caller-defined context data for the callbacks, a new
structure BN_GENCB is defined that encapsulates this; a pointer to the
structure is passed to all such functions instead.
This wrapper structure allows the encapsulation of "old" and "new" style
callbacks - "new" callbacks return a boolean result on the understanding
that returning FALSE should terminate keygen/primality processing. The
BN_GENCB abstraction will allow future callback modifications without
needing to break binary compatibility nor change the API function
prototypes. The new API functions have been given names ending in "_ex" and
the old functions are implemented as wrappers to the new ones. The
OPENSSL_NO_DEPRECATED symbol has been introduced so that, if defined,
declaration of the older functions will be skipped. NB: Some
openssl-internal code will stick with the older callbacks for now, so
appropriate "#undef" logic will be put in place - this is in case the user
is *building* openssl (rather than *including* its headers) with this
symbol defined.
There is another change in the new _ex functions; the key-generation
functions do not return key structures but operate on structures passed by
the caller, the return value is a boolean. This will allow for a smoother
transition to having key-generation as "virtual function" in the various

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.

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.

really necessary and saves memory to boot. This required a small
change in bn_mul_part_recursive() and the addition of variants of
bn_cmp_words(), bn_add_words() and bn_sub_words() that can take arrays
with differing sizes.
The test results show a performance that very closely matches the
original code from before my constification. This may seem like a
very small win from a performance point of view, but if one remembers
that the variants of bn_cmp_words(), bn_add_words() and bn_sub_words()
are not at all optimized for the moment (and there's no corresponding
assembler code), and that their use may be just as non-optimal, I'm
pretty confident there are possibilities...
This code needs reviewing!
two functions that did expansion on in parameters (BN_mul() and
BN_sqr()). The problem was solved by making bn_dup_expand() which is
a mix of bn_expand2() and BN_dup().
full version number and not just 0. This should mark the shared
libraries as not backward compatible. Of course, this should be
changed again when we can guarantee backward binary compatibility.
load the "external" built-in engines (those that require DSO). This
makes linking with libdl or other dso libraries non-mandatory.
Change 'openssl engine' accordingly.
Change the engine header files so some declarations (that differed at
that!) aren't duplicated, and make sure engine_int.h includes
engine.h. That way, there should be no way of missing the needed
info.
implementation is contained in the application, and the capability
string building part should really be part of the engine library.
This is therefore an experimental hack, and will be changed in the
near future.
- 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.
record-oriented fashion. That means that every write() will write a
separate record, which will be read separately by the programs trying
to read from it. This can be very confusing.
The solution is to put a BIO filter in the way that will buffer text
until a linefeed is reached, and then write everything a line at a
time, so every record written will be an actual line, not chunks of
lines and not (usually doesn't happen, but I've seen it once) several
lines in one record. Voila, BIO_f_linebuffer() is born.
Since we're so close to release time, I'm making this VMS-only for
now, just to make sure no code is needlessly broken by this. After
the release, this BIO method will be enabled on all other platforms as
well.
BN_mod_mul_montgomery, which calls bn_sqr_recursive
without much preparation.
bn_sqr_recursive requires the length of its argument to be
a power of 2, which is not always the case here.
There's no reason for not using BN_sqr -- if a simpler
approach to squaring made sense, then why not change
BN_sqr? (Using BN_sqr should also speed up DH where g is chosen
such that it becomes small [e.g., 2] when converted
to Montgomery representation.)
Case closed :-)
process when some symbols are missing. Instead, all needed info is
saved in the .num files, including what conditions are needed for a
specific symbol to exist.
This was needed for the work I'm doing with shared libraries under
VMS.
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 :-(
