[PATCH 4.14 17/45] net/tls: Fix connection stall on partial tls record

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Andre Tomt <andre@xxxxxxxx>

[ Upstream commit 080324c36ade319f57e505633ab54f6f53289b45 ]

In the case of writing a partial tls record we forgot to clear the
ctx->in_tcp_sendpages flag, causing some connections to stall.

Fixes: c212d2c7fc47 ("net/tls: Don't recursively call push_record during tls_write_space callbacks")
