option to prevent BEAST attack. See [Bug #5353].
In OpenSSL, OP_DONT_INSERT_EMPTY_FRAGMENTS is used to prevent
TLS-CBC-IV vulunerability described at
http://www.openssl.org/~bodo/tls-cbc.txt
It's known issue of TLSv1/SSLv3 but it attracts lots of attention
these days as BEAST attack. (CVE-2011-3389)
Until now ossl sets OP_ALL at SSLContext allocation and call
SSL_CTX_set_options at connection. SSL_CTX_set_options updates the
value by using |= so bits set by OP_ALL cannot be unset afterwards.
This commit changes to call SSL_CTX_set_options only 1 time for each
SSLContext. It sets the specified value if SSLContext#options= are
called and sets OP_ALL if not.
To help users to unset bits in OP_ALL, this commit also adds several
constant to SSL such as
OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS. These constants were
not exposed in Ruby because there's no way to unset bits in OP_ALL
before.
Following is an example to enable 0/n split for BEAST prevention.
ctx.options = OP_ALL & ~OP_DONT_INSERT_EMPTY_FRAGMENTS

* ext/openssl/ossl.c (ossl_pem_passwd_cb0, ossl_verify_cb):
pem_passwd_cb and verify_cb ignores the exception raised in a
callback proc so it should clear $! for subsequent execution.
That's said, both subsequent processes for pem_passwd_cb and
verify_cb raises another exception before leaking $! to Ruby world.
We cannot test this fix in Ruby land.

given as a parameter.
!!! Keys generated by this code (trunk after 2011-09-01) must be

t = Thread.new { print "."; sleep 0.1 }
key = OpenSSL::PKey::RSA.new(2048)
#=> Thread t works in parallel with public key generation if
OS/machine allows it.
This works with OpenSSL >= 0.9.8. From this version, it has new
public key generation function which allows us to interrupt the
execution while pkey generation iterations.
* ext/openssl/extconf.rb: Check existence of OpenSSL's new public key
generation function. (DH_generate_parameters_ex,
DSA_generate_parameters_ex and RSA_generate_key_ex.
* ext/openssl/ossl_pkey.{h,c} (ossl_generate_cb_2,
ossl_generate_cb_stop): Added new callback function for OpenSSL pkey
generation which handles Thread interruption by Ruby.
ossl_generate_cb_stop is the unblock function(ubf) for Ruby which
sets a stop flag. New pkey generation callback ossl_generate_cb_2
checks the stop flag at each iterations of OpenSSL and interrupts
pkey generation when the flag is set.
* ext/openssl/ossl_pkey_dsa.c (dsa_generate): Call
rb_thread_blocking_region with the above unblock function to release
GVL while pkey generation.
* ext/openssl/ossl_pkey_rsa.c (rsa_generate): ditto.
* ext/openssl/ossl_pkey_dh.c (dh_generate): ditto.
* test/openssl/test_pkey_{dh,dsa,rsa}.rb: Test it.

SEGV from AES encryption/decryption. Processing data by
Cipher#update without initializing key (meaningless usage of Cipher
object since we don't offer a way to export a key) could cause SEGV.
In OpenSSL, the EVP which has EVP_CIPH_RAND_KEY flag (such as DES3)
allows uninitialized key, but other EVPs (such as AES) does not
allow it. Calling EVP_CipherUpdate() without initializing key causes
SEGV so we set the data filled with "\0" as the key by default. See
#2768.
* test/openssl/test_cipher.rb: test it.

SSLError from SSLSocket just after invoking SSLSocket#close.
OpenSSL's SSL_shutdown could try to send alert packet and it might
set SSLerr(global error stack) as the result. It causes the next
SSL read/write operation to fail by unrelated reason.
By design, we're ignoring any error at SSL_shutdown() so we clear
global error stack after SSL_shutdown is called. See #5039.
