From 3a4b755ce5b4be1981d12d5b6f3eb563ef079707 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Thu, 25 Oct 2012 17:07:29 -0700 Subject: Fix bug #9329 - Directory listing with SeBackup can crash smbd. When we do a become_root()/unbecome_root() pair to temporarily raise privilege, this NULLs out the NT token. If we're within a become_root()/unbecome_root() pair then return the previous token on the stack as our NT token. This is what we should be using to check against NT ACLs in the file server. This copes with security context changing when removing a file on close under the context of another user (when 2 users have a file open, one sets delete on close and then the other user has to actually do the delete).
