Subject[PATCH 4.14 56/71] tls: return -EBUSY if crypto_info is already set
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sabrina Dubroca <sd@queasysnail.net>


[ Upstream commit 877d17c79b66466942a836403773276e34fe3614 ]

do_tls_setsockopt_tx returns 0 without doing anything when crypto_info
is already set. Silent failure is confusing for users.

Fixes: 3c4d7559159b ("tls: kernel TLS support")
