Todd Short 5c753de668 Fix session ticket and SNI
When session tickets are used, it's possible that SNI might swtich the
SSL_CTX on an SSL. Normally, this is not a problem, because the
initial_ctx/session_ctx are used for all session ticket/id processes.

However, when the SNI callback occurs, it's possible that the callback
may update the options in the SSL from the SSL_CTX, and this could
cause SSL_OP_NO_TICKET to be set. If this occurs, then two bad things
can happen:

1. The session ticket TLSEXT may not be written when the ticket expected
flag is set. The state machine transistions to writing the ticket, and
the client responds with an error as its not expecting a ticket.
2. When creating the session ticket, if the ticket key cb returns 0
the crypto/hmac contexts are not initialized, and the code crashes when
trying to encrypt the session ticket.

To fix 1, if the ticket TLSEXT is not written out, clear the expected
ticket flag.
To fix 2, consider a return of 0 from the ticket key cb a recoverable
error, and write a 0 length ticket and continue. The client-side code
can explicitly handle this case.

Fix these two cases, and add unit test code to validate ticket behavior.

How to add recipes
==================

For any test that you want to perform, you write a script located in
test/recipes/, named {nn}-test_{name}.t, where {nn} is a two digit number and
{name} is a unique name of your choice.

Please note that if a test involves a new testing executable, you will need to
do some additions in test/Makefile.  More on this later.


Naming convetions
=================

A test executable is named test/{name}test.c

A test recipe is named test/recipes/{nn}-test_{name}.t, where {nn} is a two
digit number and {name} is a unique name of your choice.

The number {nn} is (somewhat loosely) grouped as follows:

05  individual symmetric cipher algorithms
10  math (bignum)
15  individual asymmetric cipher algorithms
20  openssl enc
25  certificate forms, generation and verification
30  engine and evp
70  PACKET layer
80  "larger" protocols (CA, CMS, OCSP, SSL, TSA)
90  misc


A recipe that just runs a test executable
=========================================

A script that just runs a program looks like this:

    #! /usr/bin/perl
    
    use OpenSSL::Test::Simple;
    
    simple_test("test_{name}", "{name}test", "{name}");

{name} is the unique name you have chosen for your test.

The second argument to `simple_test' is the test executable, and `simple_test'
expects it to be located in test/

For documentation on OpenSSL::Test::Simple, do
`perldoc test/testlib/OpenSSL/Test/Simple.pm'.


A recipe that runs a more complex test
======================================

For more complex tests, you will need to read up on Test::More and
OpenSSL::Test.  Test::More is normally preinstalled, do `man Test::More' for
documentation.  For OpenSSL::Test, do `perldoc test/testlib/OpenSSL/Test.pm'.

A script to start from could be this:

    #! /usr/bin/perl
    
    use strict;
    use warnings;
    use OpenSSL::Test;
    
    setup("test_{name}");
    
    plan tests => 2;                # The number of tests being performed
    
    ok(test1, "test1");
    ok(test2, "test1");
    
    sub test1
    {
        # test feature 1
    }
    
    sub test2
    {
        # test feature 2
    }
    

Changes to test/Makefile
========================

Whenever a new test involves a new test executable you need to do the
following (at all times, replace {NAME} and {name} with the name of your
test):

* among the variables for test executables at the beginning, add a line like
  this:

    {NAME}TEST= {name}test

* add `$({NAME}TEST)$(EXE_EXT)' to the assignment of EXE:

* add `$({NAME}TEST).o' to the assignment of OBJ:

* add `$({NAME}TEST).c' to the assignment of SRC:

* add the following lines for building the executable:

    $({NAME}TEST)$(EXE_EXT): $({NAME}TEST).o $(DLIBCRYPTO)
           @target=$({NAME}TEST); $(BUILD_CMD)
