From 0fd357b48642f16c3adf8ed474f299daecef2613 Mon Sep 17 00:00:00 2001 From: Justus Winter <4winter@informatik.uni-hamburg.de> Date: Tue, 8 Oct 2013 15:49:02 +0200 Subject: Revert "tmpfs: drop privileges in the tmpfs translator" This reverts commit 7075bc11289355478659cd1610632a9299734afc. Dropping the unix privileges of the tmpfs translator causes problems with the passive translator startup. The function fshelp_fetch_root creates an auth handle containing the processes original UID and GID. But if the privileges were dropped before, this operation fails with EPERM. This commit also broke mkfifo(3), possibly for similar or related reasons. * tmpfs/tmpfs.c (main): Do not drop all privileges. --- tmpfs/tmpfs.c | 6 ------ 1 file changed, 6 deletions(-) (limited to 'tmpfs/tmpfs.c') diff --git a/tmpfs/tmpfs.c b/tmpfs/tmpfs.c index 1872a7df..7da3dd58 100644 --- a/tmpfs/tmpfs.c +++ b/tmpfs/tmpfs.c @@ -29,7 +29,6 @@ the Free Software Foundation, 675 Mass Ave, Cambridge, MA 02139, USA. */ #include #include #include -#include char *diskfs_server_name = "tmpfs"; char *diskfs_server_version = HURD_VERSION; @@ -438,11 +437,6 @@ main (int argc, char **argv) /* We must keep the REALNODE send right to remain the active translator for the underlying node. */ - /* Drop all privileges. */ - err = setnullauth(); - if (err) - error (1, err, "Could not drop privileges"); - pthread_mutex_unlock (&diskfs_root_node->lock); /* and so we die, leaving others to do the real work. */ -- cgit v1.2.3
