Additionaly, shut down if tls is in use if either side of the socket goes away, since we higher level TLS operations (tls_read and write) will require the socket to be both readable and writable as we can get TLS_WANT_POLLIN or TLS_WANT_POLLOUT on either operation. deraadt@ buying it. found by sthen@

Port of Edlinger's Fix for CVE-2019-1563 from OpenSSL 1.1.1 (old license) tests from bluhm@ ok jsing commit e21f8cf78a125cd3c8c0d1a1a6c8bb0b901f893f Author: Bernd Edlinger <bernd.edlinger@hotmail.de> Date: Sun Sep 1 00:16:28 2019 +0200 Fix a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey An attack is simple, if the first CMS_recipientInfo is valid but the second CMS_recipientInfo is chosen ciphertext. If the second recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct encryption key will be replaced by garbage, and the message cannot be decoded, but if the RSA decryption fails, the correct encryption key is used and the recipient will not notice the attack. As a work around for this potential attack the length of the decrypted key must be equal to the cipher default key length, in case the certifiate is not given and all recipientInfo are tried out. The old behaviour can be re-enabled in the CMS code by setting the CMS_DEBUG_DECRYPT flag.

So the library currently falls back to very old SCA-vulnerable code if the cofactor is not present. This PR allows EC_GROUP_set_generator to compute the cofactor for all curves of cryptographic interest. Steering scalar multiplication to more SCA-robust code. This issue affects persisted private keys in explicit parameter form, where the (optional) cofactor field is zero or absent. It also affects curves not built-in to the library, but constructed programatically with explicit parameters, then calling EC_GROUP_set_generator with a nonsensical value (NULL, zero). The very old scalar multiplication code is known to be vulnerable to local uarch attacks, outside of the OpenSSL threat model. New results suggest the code path is also vulnerable to traditional wall clock timing attacks.
