libdes (which is still used out there) or other des implementations,
the OpenSSL DES functions are renamed to begin with DES_ instead of
des_. Compatibility routines are provided and declared by including
openssl/des_old.h. Those declarations are the same as were in des.h
when the OpenSSL project started, which is exactly how libdes looked
at that time, and hopefully still looks today.
The compatibility functions will be removed in some future release, at
the latest in version 1.0.
like des_read_password and friends (backward compatibility functions
using this new API are provided). The purpose is to remove prompting
functions from the DES code section as well as provide for prompting
through dialog boxes in a window system and the like.
and make all files the depend on it include it without prefixing it
with openssl/.
This means that all Makefiles will have $(TOP) as one of the include
directories.
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.
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.
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.]
PR:
With this change, the following is provided and present at all times
(meaning CRYPTO_MDEBUG is no longer required to get this functionality):
- hooks to provide your own allocation and deallocation routines.
They have to have the same interface as malloc(), realloc() and
free(). They are registered by calling CRYPTO_set_mem_functions()
with the function pointers.
- hooks to provide your own memory debugging routines. The have to
have the same interface as as the CRYPTO_dbg_*() routines. They
are registered by calling CRYPTO_set_mem_debug_functions() with
the function pointers.
I moved everything that was already built into OpenSSL and did memory
debugging to a separate file (mem_dbg.c), to make it clear what is
what.
With this, the relevance of the CRYPTO_MDEBUG has changed. The only
thing in crypto/crypto.h that it affects is the definition of the
MemCheck_start and MemCheck_stop macros.
