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...
it cope with OpenBSD which doesn't understand "RTLD_NOW".
* 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.
* "no-dso" option available in Configure so that all DSO methods will
return NULL, overriding any support the platform might otherwise
have built.
* dlfcn_no_h config string now available rather than just dlfcn. This
is for platforms that have dlfcn.h functions but do not have (or
need) the dlfcn.h header file.
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").
Thanks to Richard Levitte, who is responsible for the dso_dl.c support,
understanding the trickier aspects of the build process, and giving great
feedback on everything else.
[Don't use this stuff if you're easily offended by changes to the
interface or behaviour - it's still work in progress.]
