bad, so let's not check OPENSSL_NO_ENGINE in those places. Fortunately, all
the header files where the problem existed include ossl_typ.h, which makes
a 'forward declaration' of the ENGINE type.
evp.h.
Application authors BEWARE! If you have had the habit to count on
evp.h to provide all those lower-level algorithm functions, you need
to think again! Please change your programs NOW, or you will be sorry
when 0.9.8 gets release (it's quite some time away...).
was that they weren't really needed any more for EVP itself. However,
it seems like soma applications (I know about OpenSSH, but there may
be more) used evp.h as the 'load all' header file, which makes sense
since we try our best to promote the use of EVP instead of the lower
level crypto algorithms. Therefore, I put the inclusions back so
the application authors don't get too shocked by all the errors they
would otherwise get.
Thanks to Theo de Raadt for making us aware of this.
See crypto/engine/README for details.
- it also removes openbsd_hw.c from the build (that functionality is
going to be available in the openbsd ENGINE in a upcoming commit)
- evp_test has had the extra initialisation added so it will use (if
possible) any ENGINEs supporting the algorithms required.
distinction (which does not work well because if CRYPTO_MDEBUG is
defined at library compile time, it is not necessarily defined at
application compile time; and memory debugging now can be reconfigured
at run-time anyway). To get the intended semantics, we could just use
the EVP_DigestInit_dbg unconditionally (which uses the caller's
__FILE__ and __LINE__ for memory leak debugging), but this would make
memory debugging inconsistent. Instead, callers can use
CRYPTO_push_info() to track down memory leaks.
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.
