Bug ID: 1436961
Summary: xmonad-mate: Programs started from menus don't have
access to ssh-agent
Product: Fedora
Version: 25
Component: xmonad
Severity: medium
Assignee: mathstuf(a)gmail.com
Reporter: dgibson(a)redhat.com
QA Contact: extras-qa(a)fedoraproject.org
CC: haskell-devel(a)lists.fedoraproject.org,
mathstuf(a)gmail.com, petersen(a)redhat.com
Description of problem:
When using XMonad with MATE, programs which use ssh internally don't seem to be
able to access the ssh-agent, and request passwords unexpectedly. The same
programs started from a terminal are able to access the ssh-agent and don't
request passwords.
Version-Release number of selected component (if applicable):
xmonad-mate-0.12-2.fc25.x86_64
ghc-xmonad-0.12-2.fc25.x86_64
openssh-clients-7.4p1-4.fc25.x86_64
mate-session-manager-1.16.1-1.fc25.x86_64
How reproducible:
100%
Steps to Reproduce:
1. Start xmonad-mate session
2. Open a terminal and add a key with ssh-add
3. From the MATE menus, run a program which uses ssh internally, such as
vinagre (with proxy through SSH enabled) or virt-manager (with a qemu+ssh
connection to the backend)
4. Attempt to connect to a host where you have ssh public key authorization
Actual results:
Program prompts for a password on the remote host.
Expected results:
Connects without password, using the key already given to the ssh-agent.
Additional info:
Running the same program (e.g. vinagre or virt-manager) from a terminal behaves
as expected, using the key in the agent to connect without further
authentication.

Can you try this build for f26
https://koji.fedoraproject.org/koji/buildinfo?buildID=834314 and see if it
helps?
I can backport it to f25.
So this is probably a duplicate of bug 1413338.

There's an error message from ssh-add:
umbus:~$ ssh-add
Enter passphrase for /home/dwg/.ssh/id_ed25519:
Could not add identity "/home/dwg/.ssh/id_ed25519": communication with agent

Not sure where I'd look for logs.
I can supply an strace if you want - but obviously I'll need to redact my
private key and passphrase from it first.

(Perhaps bug 1413338 is something else.)
I am not sure to be honest - I guess I should try to reproduce the problem.
These days I don't use xmonad-mate (or xmonad) alas.
I assume Fedora Mate is okay?
It might be worth trying to test on a fresh install or at least a new account.
Not sure how much the strace will help, but if you think it could provide
useful information for tracking down the problem, then please.

The problem is, alas, worse in Fedora 26. Now, ssh agent doesn't work from any
programs.
I have, however, been able to track down the problem a bit further.
Initially, xmonad-mate was starting up with gnome-keyring. I think the ssh
agent included in gnome-keyring was working - except that it doesn't do what I
need because of bug 1248916.
I disable the gnome-keyring ssh component in autostart, and now ssh-agent is
started as well as gnome-keyring. Unfortunately, SSH_AUTH_SOCK is still
pointed at gnome-keyring, instead of ssh-agent, hence the breakage.
I did notice that in the tree of processes under lightdm, there are two notable
subtrees - things under the xmonad process (including terminals started with
alt-shift-enter) and things under the mate-session process (things started from
menus).
My guess is that in F25 (where, again, both ssh-agent and gnome-keyring were
started) the things under xmonad had SSH_AUTH_SOCK set to ssh-agent, and those
under mate-session pointed at gnome-keyring.
Now, under F26, they're at least consistent - fixing bug 1413338, but always
point at gnome-keyring, even when they shouldn't.

I'm having a fair bit of trouble working out where in the tangle of scripts
between the DM and the xmonad-mate session the ssh-agent and keyring are
started, and who is responsible for setting SSH_AUTH_SOCK.
I suspect bug 1401222 is another dupe, though there's not much info there.

Thank you for the comments.
Sorry for the slow reply.
Could you try with an ordinary Mate session?
I assume that works...
Maybe the way xmonad is being started is not orthodox.

--- Comment #11 from David Gibson <dgibson(a)redhat.com> ---
Sorry I've taken so long to reply to this - I've been very busy at my day job
(and I have a limited workaround that makes the current situation almost
bearable).
So, in fact this *does* happen with an ordinary Mate session. And, to my
surprise, with a plain xmonad session. And with a GNOME3 session.
Everything now, appears to insist on using gnome-keyring as the ssh key agent,
despite the fact that it suffers a serious limitation (bug 1248916). It used
to be that if you disabled gnome-keyring's ssh agent component in the startup
programs you'd get the plain, working ssh-agent instead, but that's no longer
the case. The xsessions for MATE, xmonad, and xmonad-mate start gnome-keyring
with ssh agent enabled anyway.
At least xmonad-mate (forgot to check the others) does _start_ ssh-agent, but
SSH_AUTH_SOCK is pointing to gnome keyring instead, so it's not very useful (my
workaround is based on manually altering SSH_AUTH_SOCK in each shell I start).
GNOME3 seems to be even worse - when I disable gnome keyring from the startup
programs, I don't get any SSH_AUTH_SOCK at all.

I think it makes sense to move it, but I haven't figured out where yet. I
haven't managed to decipher the X startup scripts enough to figure out where
SSH_AUTH_SOCK is being set. I don't know if it's the same place for all the
desktop environment options.

Great suggestion. Turns out startx does *not* give the same result.
When I run 'startx', I get a GNOME3 session - haven't worked out how to point
it at xmonad-mate yet, but SSH_AUTH_SOCK is set correctly to a real ssh-agent.
Still trying to work out where the script path differences are.

Tried gdm, but same results as lightdm. I think I'm going to need to break out
SystemTap or something to trace through the myriad scripts and work out where
SSH_AUTH_SOCK is being set.

--- Comment #20 from David Gibson <dgibson(a)redhat.com> ---
So, I've finally had a chance to investigate this a bit more. I think the
problem is in /bin/xmonad-start after all.
Specifically this stanza:
if [ -x /usr/bin/gnome-keyring-daemon ]; then
eval $(gnome-keyring-daemon --start)
export GNOME_KEYRING_SOCKET
export GNOME_KEYRING_PID
fi
The trouble is that this invokes gnome-keyring-daemon dependent only on whether
it is installed, not whether it is appropriate or configured for the desktop
setup we're entering. The output of gnome-keyring-daemon includes setting
SSH_AUTH_SOCK to point to itself, which is again 'eval'ed unconditionally by
the script.
By poking around in /proc, I've determined that SSH_AUTH_SOCK *was* set
correctly (pointing to ssh-agent) in the parent process of xmonad-start. So
AFAICT, the DM scripts are correctly setting it, but then xmonad-start is
overwriting it unconditionally with gnome-keyring-daemon.

I'm not sure. I think that would work well for me personally, but it might
break things for people who do want to use gnome-keyring rather than the
openssh ssh-agent - i.e. it might unfix bug 1413338.

I could add an envvar or logic/workaround to check/reset SSH_AUTH_SOCK.

There absolutely is a gnome-keyring bug here (bz 1248916). However, that's
been a known bug there for ages, and they don't seem to have much interest in
fixing it.
So, I still think having the xmonad scripts work (again) with the openssh agent
is a good idea.

Moving to F27, since the bug is certainly still there.
In F28, it's a bit more complicated. The scripts still seem to be pointing at
gnome-keyring instead of ssh-agent, despite configuration otherwise. However
it looks like gnome-keyring now supports ed25519 keys, so that no longer causes
a problem for me.
