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.

cast their type-specific STACK into a real STACK and call the underlying sk_*** function. The problem is that if the STACK_OF(..) parameter being passed in has a "const *" qualifier, it is discarded by the cast. I'm currently implementing a fix for this but in the mean-time, this is one case I noticed (a few type-specific sk_**_num() functions pass in const type-specific stacks). If there are other errors in the code where consts are being discarded, we will similarly not notice them. yuck.

More EVP cipher revision. Change EVP_SealInit() and EVP_OpenInit() to handle cipher parameters. Make it possible to set RC2 and RC5 params. Make RC2 ASN1 code use the effective key bits and not the key length. TODO: document how new API works.

There's no trace of it being implemented and it doesn't seem to have been intended given that it is prototyped with a BIO yet there was a BIO- specific version added in at the same time.

Second phase of EVP cipher overhaul. Change functions like EVP_EncryptUpdate() so they now return a value. These normally have software only implementations which cannot fail so this was acceptable. However ciphers can be implemented in hardware and these could return errors.

Beginnings of EVP cipher overhaul. This should eventually enhance and tidy up the EVP interface. This patch adds initial support for variable length ciphers and changes S/MIME code to use this. Some other library functions need modifying to support use of modified cipher parameters. Also need to change all the cipher functions that should return error codes, but currenly don't. And of course it needs extensive testing...
