- Make sure PCURSORINFO is defined even on systems that do not provide it.
- Change the reference to Peter Gutmann's paper.
- Make sure we don't walk the whole heap lists for performance reasons.
Jeffrey Altman suggests following Peter Gutmann's advice to keep it
to 50 heap entries per heap list.
handle an externally provided "static" buffer as well a a dynamic
buffer. The "static" buffer is filled first, but if overflowed, the
dynamic buffer is used instead, being allocated somewhere i the heap.
This combines the benefits of putting the output in a preallocated
buffer (on the stack, for example) and in a buffer that grows
somewhere in the heap.
add some whitespace for 'if ()', 'for ()', 'while ()' to distinguish
keywords from function names, and finally remove parens around return
values (why be stingy with whitespace but fill the source code
with an abundance of parentheses that are not needed to structure
expressions for readability?).
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 :-(
If some other thread deletes the BIO that one thread needs for
BIO_write, then there's a lot of trouble anyway; there's
nothing special about calling the callback.
Returning -1 for an attempt to read from an empty buffer is empty is
not an error that should be signalled via the error queue, it's a
'retry read' condition and is signalled as such.
This allows intermediate CAs to be created more easily.
PKCS12_create() now checks private key matches certificate.

records, EVP_EncodeUpdate() may misbehave. This happens when there's
a record boundary between the two ending b64 equal signs, which makes
EVP_EncodeUpdate think there has been more than one EOF, and therefore
add an extra NUL at the end of the output buffer. This fix corrects
that problem.

In s23_clnt.c, don't use special rollback-attack detection padding

functions. These are intended to be replacements
for the ancient ASN1_STRING_print() and X509_NAME_print()
functions.
The new functions support RFC2253 and various pretty

"unicode_start" script is run).

size) through the base64 filter, b64_write() messes up it's parameters
in such a way that instead of writing correct base64 output, the first
4 characters of that output is repeated over and over. This fix
corrects that problem.
it wants to stir the pool using ssleay_rand_add. This fix provides the
possibility to call ssleay_rand_add inside a locked state by simply telling
it not to do any locking through a static variable. This isn't the most
elegant way one could do this, but it does retain thread safety during the
stirring process.
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...

Fix ASN1 long form tag encoding. This never

could be done automagically, much like the numbering in libeay.num and
ssleay.num. The solution works as follows:
- New object identifiers are inserted in objects.txt, following the
syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!). Additions are OK, as well as consistent name changes.

into lexical order. Previously it depended on
the order of files in the directory.
This should now mean that all systems will
agree on the order of safestack.h and will
not change it needlessly and avoid massive
needless commits to safestack.h in future.
It wont however avoid this one :-(

This is mostly a work around for the old VC++ problem
that it treats func() as func(void).
Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.
The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.
Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)
Also, make sure empty slots of the dynamic lock stack are used.
Actually, I'm not really sure this is the right thing to do, and may
remove it, with an endlessly growing stack as result...

Also, to avoid one thread freeing a lock that is used by another, a

Note that it's implemented in such a way that the locking itself is
done through the same CRYPTO_lock function as the static locks.
WARNING: This is currently experimental and untested code (it will get
tested soon, though :-)).
sk_whatever_insert and sk_whatever_set immediately reveals the subtle
difference in parameter order.
Change mkstack.pl so that safestack.h is not rewritten when
nothing has changed.
After some messing around this seems to work but needs
a few more tests. Working out the syntax for sk_set_cmp_func()
(cast it to a function that itself returns a function pointer)
was painful :-(
Needs some testing to see what other compilers think of this
syntax.
Also needs similar stuff for ASN1_SET_OF etc etc.
"symbols" including functions (of all prototypes( and variables. Whilst
casting any function type to another violates ANSI C (I believe), it is
a necessary evil in shared-library APIs. However, it is quite
conceivable that functions in general and data symbols could very well
be represented differently to each other on some systems, as Bodo said;

I agree. So this change splits the "dso_bind" handler in DSO_METHOD
into "dso_bind_var" and "dso_bind_func". Similarly the exported
function DSO_bind() has been split in two. I've also put together
changes for the various DSO_METHOD implementations, but so far only
DSO_dlfcn() has been tested. BTW: The prototype for dso_bind had been
a bit strange so I've taken the opportunity to change its shape (in
both variations).
Also, the README has been updated - particularly with a note about
using customised native name-translation for shared libraries (and that
you can't do it yet).
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.
was a really bad idea. For example, the following:
#include <x509.h>
#include <bio.h>
#include <asn1.h>
would make sure that things like ASN1_UTCTIME_print() wasn't defined
unless you moved the inclusion of bio.h to above the inclusion of
x509.h. The reason is that x509.h includes asn1.h, and the
declaration of ASN1_UTCTIME_print() depended on the definition of
HEADER_BIO_H. That's what I call an obscure bug.
Instead, this change makes sure that whatever header files are needed
for the correct process of one header file are included automagically,
and that the definitions of, for example, BIO-related things are
dependent on the absence of the NO_{foo} macros. This is also
consistent with the way parts of OpenSSL can be excluded at will.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
This change includes all the name changes needed throughout all C files.
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.
yet tighter, and also put some heat on the rest of the library by
insisting (correctly) that compare callbacks used in stacks are prototyped
with "const" parameters. This has led to a depth-first explosion of
compiler warnings in the code where 1 constification has led to 3 or 4
more. Fortunately these have all been resolved to completion and the code
seems cleaner as a result - in particular many of the _cmp() functions
should have been prototyped with "const"s, and now are. There was one
little problem however;
X509_cmp() should by rights compare "const X509 *" pointers, and it is now
declared as such. However, it's internal workings can involve
recalculating hash values and extensions if they have not already been
setup. Someone with a more intricate understanding of the flow control of
X509 might be able to tighten this up, but for now - this seemed the
obvious place to stop the "depth-first" constification of the code by
using an evil cast (they have migrated all the way here from safestack.h).
Fortunately, this is the only place in the code where this was required
to complete these type-safety changes, and it's reasonably clear and
commented, and seemed the least unacceptable of the options. Trying to
take the constification further ends up exploding out considerably, and
indeed leads directly into generalised ASN functions which are not likely
to cooperate well with this.
same one). However, the first will temporarily break things until the
second comes through. :-)
The safestack.h handling was mapping compare callbacks that externally
are of the type (int (*)(type **,type **)) into the underlying callback
type used by stack.[ch], which is (int (*)(void *,void *)). After some
degree of digging, it appears that the callback type in the underlying
stack code should use double pointers too - when the compare operations
are invoked (from sk_find and sk_sort), they are being used by bsearch
and qsort to compare two pointers to pointers. This change corrects the
prototyping (by only casting to the (void*,void*) form at the moment
it is needed by bsearch and qsort) and makes the mapping in safestack.h
more transparent. It also changes from "void*" to "char*" to stay in
keeping with stack.[ch]'s assumed base type of "char".
Also - the "const" situation was that safestack.h was throwing away
"const"s, and to compound the problem - a close examination of stack.c
showed that (const char **) is not really achieving what it is supposed
to when the callback is being invoked, what is needed is
(const char * const *). So the underlying stack.[ch] and the mapping
macros in safestack.h have all been altered to correct this.
What will follow are the vast quantities of "const" corrections required
in stack-dependant code that was being let "slip" through when
safestack.h was discarding "const"s. These now all come up as compiler
warnings.
