From 2c864ba8fcf50246920d09feaa2b02f3a3dfd52c Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Mon, 27 May 2019 13:07:12 +0200 Subject: mesg: avoid 'ttyname failed: Success' message The ttyname(3) can fail to access /dev/ path, and that will cause function to fail without setting errno value with result of rather confusing error message. Lets start setting stdin permission via /proc when this happens as a go-around, with hope kernel following symlink does not fail. Ok, noted, that hopes of symlink follow working are pretty slim. Based on patch from Sami Kerola .
