From 41126226e186d92a45ed664e546abb5204588359 Mon Sep 17 00:00:00 2001 From: Miloslav Trmac Date: Fri, 18 Apr 2008 13:30:14 -0700 Subject: [patch 1/2] audit: let userspace fully control TTY input auditing Remove the code that automatically disables TTY input auditing in processes that open TTYs when they have no other TTY open; this heuristic was intended to automatically handle daemons, but it has false positives (e.g. with sshd) that make it impossible to control TTY input auditing from a PAM module. With this patch, TTY input auditing is controlled from user-space only. On the other hand, not even for daemons does it make sense to audit "input" from PTY masters; this data was produced by a program writing to the PTY slave, and does not represent data entered by the user.
