nginx -V: 1.15.8 and 1.17.8

Description (last modified by rudirodi@…)

nginx Version: 1.15.8 and 1.17.8

WHEN:

Request Method: POST
any POST body is sent
NGINX returns 403

THEN:
NGINX is not sending a close_notify Alert to close the connection.

Why it looks like a bug:

When no POST Body is included in the request the close_notify is sent.

In 7738:554c6ae25ffc/nginx:

SSL: fixed non-working SSL shutdown on lingering close.

When doing lingering close, the socket was first shut down for writing,
so SSL shutdown initiated after lingering close was not able to send
the close_notify alerts (ticket #2056).

The fix is to call ngx_ssl_shutdown() before shutting down the socket.
