Subject: [PATCH net 0/3] tls: don't leave keys in kernel memory
Date: Wed, 5 Sep 2018 15:21:42 +0200 [thread overview]
Message-ID: <cover.1536152698.git.sd@queasysnail.net> (raw)
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.
Sabrina Dubroca (3):
tls: don't copy the key out of tls12_crypto_info_aes_gcm_128
tls: clear key material from kernel memory when do_tls_setsockopt_conf
fails
tls: zero the crypto information from tls_context before freeing
