#184773 — How to change default umask in Stretch?

The "old" methods for changing the default umask no longer work in Debian Stretch.

It appears systemd now manages umask. Can someone please describe how I can change the default umask setting in Stretch?

[toc] | [next] | [standalone]

#184783

I think the default umask is defined in /etc/profile.

 Is your question based on the documentation contained within /etc/profile and
/etc/login.defs? I don't think "systemd" changed anything, while pam may have. I
still reconfigure globally using /etc/profile.local.

I have set /etc/login.defs to a umask of 077. Also, I commented out the USERGROUPS_ENAB entry.

When I create gedit documents (for example), I am getting rw-r--r--. This does not reflect umask 077.

I then went to ~/.profile and set umask there. But this had no effect on anything.

Please advise on where "/etc/profile.local" is. I can find no such entry.

OK, you're not going to give us any details without tooth-pulling.
That sucks.  I will have to rely upon guesswork.

You used the word "login" and the word "gedit".  This tells me that you
may be concentrating, currently, one of the two following scenarios:

1) You login locally through a display manager into an X session.

2) You login locally on the Linux console and use startx to launch
   an X session.

Now, we can probably rule out #2, because you claim that modifications
to ~/.profile did not work.  There are various situations where you
*could* still be using console login + startx and have your changes in
~/.profile not take effect, but the simplest answer suggests you are
not doing that.

So, you're probably logging in through a display manager.

If you want to configure the X session that you get when logging in
through a Debian display manager, use the file ~/.xsessionrc
instead of ~/.profile.

See <https://wiki.debian.org/Xsession>.

Yes, Virginia, ~/.xsessionrc does not exist by default.  You would have
to create it.  (These days, users have to be *told* this for some reason.
They whine and moan if you don't reassure them that yes, it's OK that
a file doesn't exist and that they should create it.  Sad but true.
And this user top-posted, so I'm inclined to suspect he/she falls into
that group.)

No, I am not talking about ~/.xsession.  ~/.xsessionrc is a totally
different file.

I apologize for the omissions.

I am booting debian to GDM. I login. I then open gedit (or libreoffice, etc). I type document. I save it.

I just tried this, adding "session optional pam_umask.so umask=0077" to the end of the /etc/pam.d/login file.

No effect.

Have you tried to set in /etc/pam.d/login this:

session optional pam_umask.so umask=0077

Logout and login back after that?

Now try to add it too to the /etc/pam.d/common-session and to set it up
in /etc/login.defs to your preferred value. Of course, logout/login
after all that.

No effect.

I added  "session optional pam_umask.so umask=0077" to the end of /etc/pam.d/common-session. Then I confirmed /etc/login.defs has a umask entry. Then I logged out and back in.

A new gedit document still reports permission rw-r--r--.

Unfortunately. It looks like it is systemd thing indeed, according to
this: 

https://unix.stackexchange.com/questions/254378/how-to-set-umask-for-the-entire-gnome-session#254923

and this

https://github.com/systemd/systemd/issues/6077

It also looks like it does not have workaround. Except to touch file
from terminal before editing it in gedit( if it is login shell, for
gnome-terminal edit > profile preferences > command > run command as
login shell ). Or even better launch gedit from that terminal, it will
have right umask settings. Or, make custom shortcut that will launch
terminal and gedit from it at same time, something like gnome-terminal
-e gedit. Sorry, but not much more help with systemd involved, I'm
afraid.

#184847

So if I want to use Gnome, I'm stuck on Jessie until this Pottering guy and Gnome get off their asses and fix this mess?

This is a long established linux item missing complete functionality. There should be a lot more priority in fixing it than Pottering and Gnome are giving it.

Does anybody know, this gnome/systemd bug of umask, it this something that I will have to wait for Debian 10 before it is fixed? Or will Debian 9 implement a fix when/if gnome/systemd issues a fix?

I was hoping to be able to move to Stretch, but it's looking unlikely now.

My suggestion is simple, but would be tedious to implement. I use it
to run a program as a different user, overriding their default umask.

/home/other/bin/my-program.sh contains

#!/bin/bash
umask u=rwx,go=
/usr/bin/real-program "$@"

But it's tedious to have to replace real-program by /home/other/bin/my-program.sh
in all the places it/they might get called from. I only have to do
this once (in .bashrc) because I'm a bash/xterm/fvwm guy using
bash functions.

Cheers,
David.

Or find gnome-session (or gnome-shell - I don't recall who exactly
spawns user applications in GNOME) process pid, execute something like
this on login:

gdb -p $(pidof gnome-session) -ex 'p umask(0077)' --batch

You'll need gdb to be installed, of course.

It's beginning to sound like GNOME applications aren't even launched
by GNOME at all, but rather by systemd/dbus.  Somehow.

I'd be interested in hearing the results of your gdb experiment being
performed on the user session dbus daemon process, by someone using
GNOME.  I have no idea whether it would actually work, but if it does,
that would help us understand how this... desktop... is put together.

Couple of experiments later, which involved strace, ltrace *and*
auditctl I confirm that GNOME applications are launched by dbus-daemon
indeed. Not 'system' one, but 'session' dbus-daemon.
If you do it via gnome-shell anyway.

So, once I pinpointed spawning process, I poked it with gdb and it
changed the umask. So, correct hack for the umask in GNOME (as of
stretch) is:

gdb -p $(pgrep -U $(id -u) -f '/usr/bin/dbus-daemon --fork') \
	-ex 'p umask(0077)' --batch

GNOME Editor and other GIO applications work like how 16-bit Windows 
applications used to work.

GNOME Terminal goes yet farther and not even the first instance is the 
originally invoked process.  All instances, even the first, are 
"bus-activated".  Depending from whether there is a per-user instance of 
systemd or not, there may be a further level of indirection.

Of course, in the case where "bus activation" is configured to at least 
pass things over to some proper per-user service management, the place 
to set the ulimit for the likes of GNOME Terminal is in the per-user 
service definition for GNOME Terminal server.  With the nosh per-user 
service mangement, this would be the 
$HOME/.config/service-bundles/services/gnome-terminal-server/service/run 
program.  With systemd per-user service management this would be a 
$HOME/.config/systemd/gnome-terminal-server.service.d/ulimit.conf 
override for /usr/lib/systemd/user/gnome-terminal-server.service .

With nosh per-user service management, there is a 
$HOME/.config/service-bundles/services/gedit service, which one can 
start before attempting to run the first GNOME Editor instance; which 
would permit one to place ulimit and suchlike modifications in 
$HOME/.config/service-bundles/services/gedit/service/run .  Vanilla 
GNOME Editor does not attempt to plumb into systemd's per-user service 
management, as GNOME Terminal does; so there is no systemd equivalent here.

Found this. Reuben Thomas reported this earlier in the year. Lot of guys tracked down PIDs.

Subject: Re: How to change default umask in Stretch?

Or find gnome-session (or gnome-shell - I don't recall who exactly
spawns user applications in GNOME) process pid, execute something like
this on login:

gdb -p $(pidof gnome-session) -ex 'p umask(0077)' --batch

Or find gnome-session (or gnome-shell - I don't recall who exactly
spawns user applications in GNOME) process pid, execute something like
this on login:

gdb -p $(pidof gnome-session) -ex 'p umask(0077)' --batch

You'll need gdb to be installed, of course.

It is too early to tell.  It depends on how complex the systemd changes
would be.

Suppose they're "simple enough".  One could then backport these changes
to stretch's systemd, *test them throughoutly* -- and by that I do mean
do a very, very good job of that *and* also of reporting it -- and then
propose that the changes be accepted into a stretch point release.

So, yes, it could happen, but someone has to do the work.  I suggest
writing the patch for systemd upstream and trying to get it (or some
other solution) merged as the first step.

Note that the ideal implementation would be to inherit the umask from
whatever was set by pam or by the user's login shell as one of the
possibilities (and have that as the default, actually).  However, I am
not sure this is straightforward: it depends on how "systemd --user"
launching of user-session services works...

Actually, the ideal implementation from the GNOME point of view would be 
for these programs to pass the umask from the client process to the 
server, just like they pass open file handles, the working directory, 
environment variables (including DISPLAY), and the arguments vector.
