Subject: [PATCH net v2 0/3] tls: don't leave keys in kernel memory

There are a few places where the RX/TX key for a TLS socket is copied
to kernel memory. This series clears those memory areas when they're no
longer needed.

v2: add union tls_crypto_context, following Vakul Garg's comment
    swap patch 2 and 3, using new union in patch 3

Sabrina Dubroca (3):
  tls: don't copy the key out of tls12_crypto_info_aes_gcm_128
  tls: zero the crypto information from tls_context before freeing
  tls: clear key material from kernel memory when do_tls_setsockopt_conf
    fails
