    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 def14907.

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.

PR#3394
(cherry picked from commit 7a9d59c1)

The object file bn_lib.o is excluded from FIPS builds which causes
a linker error for BN_consttime_swap. So move definition from bn_lib.c
to bn_gf2m.c

This change is *only* needed for OpenSSL 0.9.8 which uses the 1.2
FIPS module.

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.
