4ed9388e5d A new branch for FIPS-related changes has been created with the name
OpenSSL-fips-0_9_7-stable.

Since the 0.9.7-stable branch is supposed to be in freeze and should
only contain bug corrections, this change removes the FIPS changes
from that branch.

75e3026a14 Cleanse memory using the new OPENSSL_cleanse() function.
I've covered all the memset()s I felt safe modifying, but may have missed some.

ea7150b070 The various hash #includes in rand_lcl.h *are* needed despite
<openssl/evp.h> is now used (MD_DIGEST_LENGTH definitions!).
No need to include such headers directly in md_rand.c.

323f289c48 Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

41d2a336ee e_os.h does not belong with the exported headers. Do not put it there
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.

bc36ee6227 Use new-style system-id macros everywhere possible. I hope I haven't
missed any.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

cf1b7d9664 Make all configuration macros available for application by making
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.

d6ade7422a Looks like Win32 builds do not define THREADS. However, they're still
supporting threads, which means that th assertion is supperbly
dangerous, so make sure it's not compiled under Win32, period.

a4125514f5 There's a deadlock when ssleay_rand_bytes is called the first time, since
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.

3b3bc455d0 That's it, I've seen questions about this one time too many for

go with their troubles.

7ae634de49 Since ssleay_rand_initialize() unlocks then locks CRYPTO_LOCK_RAND,
it's a good thing if ssleay_rand_status() would do the corresponding
lock and unlock as everyone else...

eb952088f0 Precautions against using the PRNG uninitialized: RAND_bytes() now
returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.

62ac293801 Always hash the pid in the first iteration in ssleay_rand_bytes,
don't try to detect fork()s by looking at getpid().
The reason is that threads sharing the same memory can have different
PIDs; it's inefficient to run RAND_seed each time a different thread
calls RAND_bytes.
