PR#3399.

In the ssl_cipher_get_evp() function, fix off-by-one errors in index validation before accessing arrays.

Bug discovered and fixed by Miod Vallat from the OpenBSD team.

PR#3375

This reverts commit 29411a0c.

Incorrect attribution.

Allow CCS after finished has been sent by client: at this point
keys have been correctly set up so it is OK to accept CCS from
server. Without this renegotiation can sometimes fail.

(cherry picked from commit 99cd6a91fcb0931feaebbb4832681d40a66fad41)

Based on an original patch by Joel Sing (OpenBSD) who also originally identified the issue.

Backport of the patch:
add ECC strings to ciphers(1), point out difference between DH and ECDH
and few other changes applicable to the 1.0.1 code base.

 * Make a clear distinction between DH and ECDH key exchange.
 * Group all key exchange cipher suite identifiers, first DH then ECDH
 * add descriptions for all supported *DH* identifiers
 * add ECDSA authentication descriptions
 * add example showing how to disable all suites that offer no
   authentication or encryption
 * backport listing of elliptic curve cipher suites.
 * backport listing of TLS 1.2 cipher suites, add note that DH_RSA
   and DH_DSS is not implemented in this version
 * backport of description of PSK and listing of PSK cipher suites
 * backport description of AES128, AES256 and AESGCM options
 * backport description of CAMELLIA128, CAMELLIA256 options

Defines SETUP_TEST_FIXTURE and EXECUTE_TEST, and updates ssl/heartbeat_test.c
using these macros. SETUP_TEST_FIXTURE makes use of the new TEST_CASE_NAME
macro, defined to use __func__ or __FUNCTION__ on platforms that support those
symbols, or to use the file name and line number otherwise. This should fix
several reported build problems related to lack of C99 support.

(cherry picked from commit 7a9d59c1)

SRP ciphersuites do not have no authentication. They have authentication
based on SRP. Add new SRP authentication flag and cipher string.

It's using an internal API that that might not be available in the shared
library.

Because of a missing include <fcntl.h> we don't have O_CREATE and don't create
the file with open() using mode 0600 but fall back to using fopen() with the
default umask followed by a chmod().

Problem found by Jakub Wilk <jwilk@debian.org>.

If application uses tls_session_secret_cb for session resumption
set the CCS_OK flag.

Check session_cert is not NULL before dereferencing it.

Unnecessary recursion when receiving a DTLS hello request can be used to
crash a DTLS client. Fixed by handling DTLS hello request without recursion.

Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue.

Return a fatal error if an attempt is made to use a zero length
master secret.

Only accept change cipher spec when it is expected instead of at any
time. This prevents premature setting of session keys before the master
secret is determined which an attacker could use as a MITM attack.

Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for reporting this issue
and providing the initial fix this patch is based on.

A buffer overrun attack can be triggered by sending invalid DTLS fragments
to an OpenSSL DTLS client or server. This is potentially exploitable to
run arbitrary code on a vulnerable client or server.

Fixed by adding consistency check for DTLS fragments.

Thanks to Jüri Aedla for reporting this issue.
