From 6ed9946f9a4f1a01846add2279e8d0640c1c2f1c Mon Sep 17 00:00:00 2001

Date: Thu, 6 May 2021 12:53:58 +0200
Subject: tools: hv: change http to https in hv_kvp_daemon.c
The patch has no functional change. Only changes the URL pointed to
in one of the comments
commit fa52a4b2d0ab416508538bb47a95167d4c94caac
Author: Alexander A. Klimov <grandmaster@al2klimov.de>
Date: Sun Jul 5 23:44:57 2020 +0200
tools: hv: change http to https in hv_kvp_daemon.c
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.
