17e757478a GPL FAQ. 
I hope this adequately summarizes the results of all those disussions.

470fa98f8a BN_mod_exp(r,a,p,m,ctx) should not be called with r == p. 
But even if this is avoided, there are still segmentation violations
(during one of the BN_free()s at the end of test_kron
in some cases, in other cases during BN_kronecker, or
later in BN_sqrt; choosing a different exponentiation
algorithm in bntest.c appears to influence when the SIGSEGV
takes place).

0ae485dc07 New format for the FAQ. We now have different sections for different 
types of questions.  Hopefully, that'll make them easier to spot, and
specially, easier to refer to.

25439b76ad Move reduction step from BN_mod_exp to BN_mod_exp_mont_word. 
Fix BN_mod_exp_simple for a==0 (mod m).
Skip useless round in BN_mod_sqrt (1 is always a square, no need
to test BN_kronecker for it).

3465dd3853 * Fix a slight bug in the state-machine. This caused the client end of a 
tunnel to not pro-actively close down when failing an SSL handshake.

* Change the cert-chain callback - originally this was the same one used in
  s_client and s_server but the output's as ugly as sin, so I've prettied
  tunala's copy output up a bit (and made the output level configurable).

* Remove the superfluous "errors" from the SSL state callback - these are just
  non-blocking side-effects.

73c2522c7c Handle special cases correctly in exponentation functions. 
test_bn still fails in the BN_sqrt test because
small primes appear to turn into zero for no
obvious reason, leading to "div by zero" errors.

d50f1bdfac Do to DH and DSA what has already been done to RSA. This involves moving 
the initialisation and cleanup of "ex_data" elements to before an init()
handler and after a finish() handler respectively.

a9376dbff9 More little changes to the tunala demo; 
* A little bit of code-cleanup
* Reformat the usage string (not so wide)
* Allow adding an alternative (usually DSA) cert/key pair (a la s_server)
* Allow control over cert-chain verify depth

14697d9d6d BN_to_montgomery expects its inputs to be in the interval 0 .. modulus-1, 
so we have to reduce the random numbers used in test_mont.

Before this change, test_mont failed in [debug-]solaris-sparcv9-gcc
configurations ("Montgomery multiplication test failed!" because
the multiplication result obtained with Montgomery multiplication
differed from the result obtained by BN_mod_mul).
Substituing the old version of bn_gcd.c (BN_mod_inverse) did not avoid
the problem.

The strange thing is that it I did not observe any problems
when using debug-solaris-sparcv8-gcc and solaris-sparcv9-cc,
as well as when compiling OpenSSL 0.9.6 in the solaric-sparcv9-gcc
configuration on the same system.

9161672950 BN_bin2bn did *not* contain an off-by-one error; 
I'm still investigating what caused the segementation fault
(maybe "make clean; make" will cure it ...).
But BN_bin2bn should always reset ret->neg.

a08bcccc67 Expand expspeed.c to make BN_kronecker timings. 
This caused a segmentation fault in calls to malloc, so I cleaned up
bn_lib.c a little so that it is easier to see what is going on.
The bug turned out to be an off-by-one error in BN_bin2bn.

that increases performance, avoiding BN_mul also helps)
