From 8eda94bde4ff004a942ed95e6348de711b0e6da9 Mon Sep 17 00:00:00 2001 From: "Alexander A. Klimov" Date: Thu, 2 Jul 2020 22:05:36 +0200 Subject: [PATCH] Replace HTTP links with HTTPS ones: vsprintf 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.
