Subject: Unable to create SSL tunnel: Global request tcpip-forward failed

Date: Fri, 11 Jul 2014 20:14:01 -0400

Package: x2goclient
Version: 4.0.2.1-pre05

On Windows, doing the following steps
1. Connect to a session.
2. Disconnect from the session (click the X)
3. Connect to the session again.

Causes the session to connect, but you receive both an error dialog
and a warning dialog with the following text:
Unable to create SSL tunnel:
Global request tcpip-forward failed

If you X out of or click OK to the error, nothing happens.
If you X out of or click OK to the warning, the session ends and you
get the message:
Title Bar: X2Go - 211
The connection with the remote server was shut down.
Please check the state of your network connection.

It is safe to assume that if I build x2goclient for windows from the
official source release of 4.0.2.1, it wold have this problem.

Most, if not all earlier 4.0.2.1 preview builds are affected too.

Subject: Some good investigation

Date: Sat, 12 Jul 2014 12:07:22 -0400

1. This bug was introduced by 1 of these 2 closely related back-to-back commits:

Don't start pulse on Windows, until we have not session with pulse support.
b9f981d979ab22db4d078c398ecc420f73a46f8c
http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=b9f981d979ab22db4d078c398ecc420f73a46f8c

Check if sound is activated before starting pulse.

2. If a start a session, log out of the session gracefully, and then
start that session again:
The pulseaudio.exe process stays running after the 1st session ends,
and this bug does not occur.

3. If I do what I originally mentioned to produce this bug:
The pulseaudio process is ended after I disconnect, and then a new one
is started for when I go to reconnect. (And this bug is triggered.)

4. Sometimes I am unable to reproduce this bug. I think that if you
start a session, end that session gracefully, start that session
again, disconnect, and then reconnect, then this bug does not occur. I
did not investigate this fully.

Correction to #3.

The PulseAudio daemon always stays running once it is started. (It
says running until you gracefully exit x2goclient.)

Subject: My plan

Date: Sat, 12 Jul 2014 17:24:34 -0400

Here's what I am going to do:

I am going to revert those 2 offending commits on the release/4.0.2.x
branch, and release 4.0.2.1+hotfix1 for Windows with them reverted. I
will mark them as fixing this bug.

(There has been and will be no 4.0.2.1 for Windows because of this bug.)

For the main branch (4.0.3.0-preview), I will clone this bug, and will
not revert those 2 commits. We will figure out how to fix the bug
without fixing these 2 commits, which are very useful. I've spent a
bunch of time but cannot figure out how to do so.

I can confirm that Alex's commit to x2goserver (rather than
x2goclient) fixes this bug.

Clean user SSHD process if connection between server and client lost.
This should fix error "Global request tcpip-forward failed".

Should I retitle and reassign this bug (#547) to x2goserver? And
should we cherry-pick it for x2goserver release/4.0.0.x &
release/4.0.1.x? We should probably release updated versions of
4.0.0.x (baikal) and 4.0.1.x at least a month before we release
x2goclient 4.0.3.0. Otherwise, people will run into this bug if they
update their clients to 4.0.3.0 but do not update their servers.

Yes, please. Can you also check for the existence of duplicate bugs?

Yes. We should cherry-pick now. Actually, the two last commits on  
x2goserver.git, but I'd suggest only to the release/4.0.1.x branch  
(Baikal needs to be superceded by a new bundle release soon).

(1)

e125f82314aa53a4d6e68f779dc1282d9edc7d5f "Set default value for  
clipboard to "both" in x2gostartagent and x2goresume-session." [1]

-> on master branch
   revert this commit
   cherry-pick it again
   do "git reset HEAD~"
   move the changelog entry to 4.0.1.16
   add bug closure if appropriate
   commit it again in Alex's name (--author="Fullname <mailaddress>")
   ...
   Then cherry-pick it to release/4.0.1.x branch

(2)

Clean user SSHD process if connection between server and client lost.  
This should fix error "Global request tcpip-forward failed".  
bf318affee905cf7cdeaa5a248dfd07bc46a8a96 [2]

-> on master branch
   revert this commit
   cherry-pick it again
   do "git reset HEAD~"
   do "git add x2goserver/lib/x2gormforward"
   move the changelog entry to 4.0.1.16
   add bug closure if appropriate
   commit it again in Alex's name (--author="Fullname <mailaddress>")

Version: 4.0.1.16-0x2go1
Status: RELEASE
Date: Fri, 26 Sep 2014 00:36:32 +0200

Changes: 
 x2goserver (4.0.1.16-0x2go1) RELEASED; urgency=low
 .
   [ Mike DePaulo ]
   * New upstream release (4.0.1.16):
     - Make X2Go Server aware of the Openbox desktop environment
       (Command: OPENBOX) (Fixes: #605)
     - Make X2Go Server aware of the IceWM desktop environment
       (Command: ICEWM) (Fixes: #606)
     - Support GNOME Flashback session (GNOME 3.8+) on distro releases such as
       Ubuntu 13.10+ and debian Jessie
       (NOTE: For most users, GNOME Flashback currently will not work.
        This requires that gnome-flashback.session actually be installed. Not
        every Linux distro has it available.
        It also requires that the gnome-session binary not require
        hardware 3D acceleration for said session. Currently, upstream GNOME
        and GNOME 3.8+ in all Linux distros do require this, only 3rd party
        builds do not. See X2Go bug #599 for example.)
       (Thanks Eugene San (eugenesan@gmail.com))
     - Fix launching GNOME 3 Fallback session (GNOME 3.4 & 3.6) on distros other
       than Ubuntu and Debian (Fixes: #599)
     - Fix support for Cinnamon 1.4 (Linux Mint 13) (Fixes: #569)
     - Fix the logic for launching Cinnamon 2.0 and 2.2 (Linux Mint 17).
       (Fixes: #572)
       NOTE: Fixing this bug in x2goserver is not sufficient to make Cinnamon 2.0
       & 2.2 to work properly with X2Go. Bug #150 in nx-libs is still a problem.
       Fixing this bug enables Cinnamon 2.0 and 2.2 to launch to their
       "fallback mode", which has many bugs and missing features when compared to
       "software rendering" mode (cinnamon2d), but is still better than nothing.
   * debian/rules:
     + Improve dh_auto_clean override.
 .
   [ Mike Gabriel ]
   * New upstream version (4.0.1.16):
     - Let x2goversion exit with an error if the X2Go component cannot be
       found.
     - Detect terminated sessions from NX log file. Also interpret a session as
       terminated if terminating just has started.
     - Detect started/starting/resumed/resuming sessions by explicitly scanning
       the NX session log file for those keywords.
     - Interpret NX sessions marked as "aborting session" as (not yet) terminated
       sessions.
     - Provide config option for server-side/global clipboard behaviour in
       x2goagent.options. (Fixes: #506).
     - Be aware of poly-instantiated /tmp directories bind-mounted under
       /tmp-inst. (Fixes: #406).
     - On suspend: Call x2goumount-session before sending SIGHUP to x2goagent.
     - Refuse client communcation if server-side hostname is not set up
       correctly (Fixes: #468).
     - Fix string comparison in x2goumount-session.
     - Fix problems with unmounting shared folders on session suspension/
       termination. Remove extra parentheses from the fusermount execution
       call. (Fixes: #407).
     - Use type -p instead of which in x2goumount-session. Suppress output
       to stdout properly.
     - Use if--then--else--fi during x2goagent resuming in x2goresume-session
       script.
     - More reliably sync the NX session state with the status information in
       the X2Go session DB.
     - x2golistdesktops: Also detect sharable desktop sessions behind abstract
       kernel namespace sockets.
     - Add logcheck rules for X2Go Server. Thanks to Frank Werner for sending
       them in.
     - Correctly use diversions from stderr to stdout in shell commands.
       (Fixes: #520).
     - Don't die if no session state file is found, as it will break X2Go
       completely after upgrading from versions << 4.0.1.16 if sessions
       are still running/suspended during package upgrade.
     - Provide support for client-side choice of clipboard security. (Fixes:
       #524).
     - Use more quotes in x2goruncommand.
     - Detect the exit of rootless applications that forked to background on
       application execution. (Fixes: #122).
     - Make x2goruncommand more robust.
     - Don't fail Xsession startup if any of the profile scripts returns
       with an error.
     - Silently timeout in x2golistdesktops if calls to x2golistsessions and/or
       xwininfo don't produce output within one second. (Fixes: #543).
     - Allow email addresses as login usernames. (Fixes: #573).
     - Abort session startup if env var $USER or $SSH_CLIENT are not set.
       (Fixes: #558).
     - Allow length of username up to 48 characters (was: 32 characters). (Fixes:
       #574).
     - Abort session if env var $HOME is not set or if $HOME contains non-ASCII
       characters. (Fixes: #397).
     - Export XAUTHORITY env var in x2goruncommand to enable privilege upgrade
       for applications started via pkexec. (Fixes: #458).
     - x2gocleansessions: Don't print to stderr if the session state file cannot
       be found. This can happen during session startups. Report to system log
       instead.
     - Don't use Perl package File::ReadBackwards anymore.
     - Fix x2gormforward for 4.0.1.x release series (the X2Go::Log Perl module
       only exists in X2Go Server >= 4.1.0.0, the 4.0.1.x release series has to
       use x2gologlevel.pm in `x2gopath lib`. (Fixes: #617).
     - Pick x2gogetagentstate from 4.1.0.0 release series and adapt to usage
       with X2Go Server 4.0.1.x. (Fixes: #619).
   * debian/control, x2goserver.spec:
     + Update versioned D: x2goagent (>= 3.5.0.25). This assures that X2Go
       works with poly-instantiated /tmp directories.
     + Make sure x2gogetagentstate gets packaged in bin:package x2goserver.
     + Bump Standards: to 3.9.5. No changes needed.
     + Mark x2goserver-pyhoca bin:package as deprecated.
     + Drop D (x2goserver): libfile-readbackwards-perl.
   * x2goserver.spec:
     + Install {libdir}/x2go/x2gormforward into bin:package x2goserver.
     + Drop R (x2goserver): perl(File::ReadBackwards).
 .
   [ Oleksandr Shneyder ]
   * New upstream version (4.0.1.16):
     - x2gostartagent, x2golistsession, x2gosuspend-session and
       x2goresume-session getting agent state from ~/.x2go/C-$SID/state. This
       should help to avoid session damage. Remove nxcleanup. (Fixes: #302,
       #511).
     - Move session file to /tmp/.x2go-$USER. (Fixes: #523).
     - Fix x2gostartagent failures if kbd is not "auto". Remove comma at end of
       options file.
     - Set default value for clipboard to "both" in x2gostartagent and
       x2goresume-session.
     - Clean user SSHD process if connection between server and client lost.
       This should fix error "Global request tcpip-forward failed". (Fixes:
       #495, #547).
