If OPENSSL_init_crypto() hasn't been called yet when ERR_get_state()
is called, it need to be called early, so the base initialization is
done. On some platforms (those who support DSO functionality and
don't define OPENSSL_USE_NODELETE), that includes a call of
ERR_set_mark(), which calls this function again.
Furthermore, we know that ossl_init_thread_start(), which is called
later in ERR_get_state(), calls OPENSSL_init_crypto(0, NULL), except
that's too late.
Here's what happens without an early call of OPENSSL_init_crypto():
=> ERR_get_state():
=> CRYPTO_THREAD_get_local():
<= NULL;
# no state is found, so it gets allocated.
=> ossl_init_thread_start():
=> OPENSSL_init_crypto():
# Here, base_inited is set to 1
# before ERR_set_mark() call
=> ERR_set_mark():
=> ERR_get_state():
=> CRYPTO_THREAD_get_local():
<= NULL;
# no state is found, so it gets allocated!!!!!
=> ossl_init_thread_start():
=> OPENSSL_init_crypto():
# base_inited is 1,
# so no more init to be done
<= 1
<=
=> CRYPTO_thread_set_local():
<=
<=
<=
<= 1
<=
=> CRYPTO_thread_set_local() # previous value removed!
<=
Result: double allocation, and we have a leak.
By calling the base OPENSSL_init_crypto() early, we get this instead:
=> ERR_get_state():
=> OPENSSL_init_crypto():
# Here, base_inited is set to 1
# before ERR_set_mark() call
=> ERR_set_mark():
=> ERR_get_state():
=> OPENSSL_init_crypto():
# base_inited is 1,
# so no more init to be done
<= 1
=> CRYPTO_THREAD_get_local():
<= NULL;
# no state is found, so it gets allocated
# let's assume we got 0xDEADBEEF
=> ossl_init_thread_start():
=> OPENSSL_init_crypto():
# base_inited is 1,
# so no more init to be done
<= 1
<= 1
=> CRYPTO_thread_set_local():
<=

=> CRYPTO_THREAD_get_local():

Reseeding is handled very differently by the classic RAND_METHOD API
and the new RAND_DRBG api. These differences led to some problems when
the new RAND_DRBG was made the default OpenSSL RNG. In particular,
RAND_add() did not work as expected anymore. These issues are discussed
on the thread '[openssl-dev] Plea for a new public OpenSSL RNG API'
and in Pull Request #4328. This commit fixes the mentioned issues,
introducing the following changes:
- Replace the fixed size RAND_BYTES_BUFFER by a new RAND_POOL API which
facilitates collecting entropy by the get_entropy() callback.
- Don't use RAND_poll()/RAND_add() for collecting entropy from the
get_entropy() callback anymore. Instead, replace RAND_poll() by
RAND_POOL_acquire_entropy().
- Add a new function rand_drbg_restart() which tries to get the DRBG
in an instantiated state by all means, regardless of the current
state (uninstantiated, error, ...) the DRBG is in. If the caller
provides entropy or additional input, it will be used for reseeding.
- Restore the original documented behaviour of RAND_add() and RAND_poll()
(namely to reseed the DRBG immediately) by a new implementation based
on rand_drbg_restart().
- Add automatic error recovery from temporary failures of the entropy
source to RAND_DRBG_generate() using the rand_drbg_restart() function.

When an SSL's context is swtiched from a ticket-enabled context to
a ticket-disabled context in the servername callback, no session-id
is generated, so the session can't be resumed.
If a servername callback changes the SSL_OP_NO_TICKET option, check
to see if it's changed to disable, and whether a session ticket is
expected (i.e. the client indicated ticket support and the SSL had
tickets enabled at the time), and whether we already have a previous
session (i.e. s->hit is set).
In this case, clear the ticket-expected flag, remove any ticket data
and generate a session-id in the session.
If the SSL hit (resumed) and switched to a ticket-disabled context,
assume that the resumption was via session-id, and don't bother to
update the session.
Before this fix, the updated unit-tests in 06-sni-ticket.conf would
fail test #4 (server1 = SNI, server2 = no SNI).
