From fcf918b966622c276749503ef9872419265af6a4 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 15 Jun 2020 18:15:42 -0500 Subject: fbcon: Use array3_size() helper in scr_memcpyw() Use array3_size() helper instead of the open-coded version in scr_memcpyw() and scr_memsetw(). These sorts of multiplication factors need to be wrapped in array3_size(). This issue was found with the help of Coccinelle and, audited and fixed manually.

Klimov" Date: Sun, 19 Jul 2020 22:37:14 +0200 Subject: video: fbdev: Replace HTTP links with HTTPS ones 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 neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
