Subject: Audio doesn't work when using Kerberos 5 (GSSAPI) authentication

Date: Tue, 12 May 2015 07:12:54 -0400

Package: x2goclient
Version: 4.0.4.0
Severity: normal

Client OS: Windows 10 64-bit Build 10074
x2goclient version: 4.0.4.0-2015.05.10-c4d21f3 (nightly build)
Server OS: Fedora 21 64-bit with almost all available updates applied
x2goserver version: 4.0.1.19-3.fc21 (from Fedora)
x2goserver-xsession version: 4.0.1.19-3.fc21 (from Fedora)

When I connect to my server using Kerberos 5 (GSSAPI) authentication
rather than password authentication, PulseAudio audio does not work.
I do have enabled "Use SSH port forwarding to tunnel sound system
connections through firewalls"

For example, "PulseAudio Volume Control" (launched from the "Sound &
Video" app menu) displays this string indefinitely:
Establishing connection to PulseAudio. Please wait...

Upon further investigation, it appears that the cookie on the client
is not the same as the cookie on the server. This is causing the
PulseAudio log on the X2Go Client to produce numerous authenitcation
errors like this:
I: [(null)] pulsecore/client.c: Created 60 "Native client (TCP/IP
client from [0:0:0:0:0:0:0:1]:28233)"
D: [(null)] pulsecore/protocol-native.c: Protocol version: remote 30, local 30
W: [(null)] pulsecore/protocol-native.c: Denied access to client with
invalid authentication data.
I: [(null)] pulsecore/client.c: Freed 60 "Native client (TCP/IP client
from [0:0:0:0:0:0:0:1]:28233)"
I: [(null)] pulsecore/protocol-native.c: Connection died.

   [ Mike DePaulo ]
   * New upstream release (4.0.4.0):
     - Windows: Do not delete saved PuTTY sessions when Kerberos 5
       (GSSAPI) authentication is enabled (Fixes: #625/#789)
     - Windows: Fix "Connection failed" "pscp" error with folder
       sharing when Kerberos 5 (GSSAPI) auth is used, and the
       server-side home dir is at a path other than /home/$USER
       (Fixes: #868)
     - Windows: Fix audio (PulseAudio) when Kerberos 5
       (GSSAPI) authentication is used (Fixes: #869)
     - Windows: Include debug build in the regular installer.
       It is an optional component during the install. It is not
       installed by default.
     - Windows: Include Pageant and PuTTYgen in the installer.
       They are optional components during the install. They are
       installed by default.
     - Windows: Add descriptions for the "components" in the installer
       (English language only at this time)
     - Windows: You can now view the version and some other info by:
       right-click on the installer -> Properties -> Details
       (English language only at this time)
     - Windows: Upgrade bundled PulseAudio from 5.0-rev18 to 6.0-11.1
       (No known impacts to X2Go, except for the fact that many needed
        patches are now included in upstream PulseAudio.)
     - Windows: Upgrade bundled VcXsrv from 1.15.2.2-xp+vc2013+x2go1 to
       1.17.0.0-1 (X2Go/Arctica Build)
       Note that X2Go Client for Windows 4.0.3.2-20150508 has an
       update to 1.15.2.6 (X2Go/Arctica), which fixes all the CVEs.
       The differences relevant to X2Go are:
         + Numerous X.org components were upgraded to new major/minor
           versions.
         + CVE-2015-0255 was fixed in VcXsrv itself
         + CVE-2015-3418 was fixed in VcXsrv itself
         + Font files no longer differ in each build due to timestamp
           differences
         + VcXsrv's bundled version of openssl was upgraded from 1.0.1k
           to 1.0.2a (fixes the multiple CVEs announced on 2015-03-19)
         + VcXsrv's bundled version of libXfont was upgraded from 1.4.8
           to 1.5.1 (Fixes CVE-2015-1802 through CVE-2015-1804)
         + VcXsrv's bundled version of freetype was updated from 2.5.3
           to 2.5.5 (fixes CVE-2014-9656 through CVE-2014-9675)
     - Windows: Update bundled Win32 OpenSSL from 1.0.1L to 1.0.1m,
       which fixes the multiple CVEs announced on 2015-03-19.
       Note that X2Go Client for Windows 4.0.3.2-20150329 has this update
       also.
     - Windows: Update bundled PuTTY from 0.63 to 0.64.
       In addition to other changes, CVE-2015-2157 has been fixed.
     - Windows: Upgrade libssh from 0.6.4 to 0.7.0 (while maintaining
       Pageant support).
       The differences relevant to X2Go are:
         + CVE-2015-3146 was fixed
         + Added support for ed25519 keys
         + Added SHA2 algorithms for HMAC
       Note that X2Go Client for Windows 4.0.3.2-20150508 has the update
       to 0.6.5, which fixes the CVE also.
     - Windows: Update bundled nxproxy (nx-libs-lite) from 3.5.0.27 to
       3.5.0.31. (bugfix & feature update)
     - Windows: Update/Upgrade bundled Cygwin components to latest
       versions as of 2015-04-25 (except for the Cygwin DLL, which was
       upgraded but not to the latest version).
       Note that all the security fixes were included in updates to
       X2Go Client for Windows 4.0.3.2
         + openssl 1.0.1k-1 -> 1.0.2a-1 (upgrade. includes security fixes
           for the multiple CVEs announced on 2015-03-19.)
         + libjpeg-turbo 1.8.1-1 -> 1.8.1-3 (security update for
           CVE-2014-9092)
         + libpng 1.5.21-2 -> libpng16 1.6.17-1 (upgrade, may improve X2Go
           performance when PNG compression is selected. Also includes the
           fix for CVE-2013-6954)
         + gcc 4.8.3-3 -> 4.9.2-3 (upgrade, may improve X2Go performance a
           little bit)
         + openssh 6.6p1-3-x2go1 -> 6.8p1-1-x2go1 (upgrade, probably not
           relevant to X2Go)
         + cygwin (DLL) 1.7.32-1 -> 1.7.33-1 (upgrade, probably not
           relevant to X2Go)
         + dash 0.5.8-2 -> 0.5.8-3 (feature update, not relevant to X2Go)
         + ncurses 5.9-20140524-1 -> 5.9-20150404-1 (update, probably
           not relevant to X2Go)
         + zlib 1.2.8-1 -> 1.2.8-3 (update, undocumented by Cygwin project)
     - Windows: Copy the exact version of each cygwin DLL from the cygwin
       binary tarballs rather than copying the "rebased" version from
       an X2Go developer's cygwin installation.
       What effect this will have on users is TBD. However, it does mean
       that we are distributing the exact DLLs that the Cygwin project
       provides, which is desirable for security.

       execution paths than release mode.
     - Add new UNUSED() macro to x2goutils.h and silence compiler warnings.
     - Fix some QMessageBox usages. There are many more places that need
       fixing...
     - Remove config_mac.sh. macbuild.sh handles this now.
     - Use the correct client build dir in macbuild.sh: client_build.
     - Only use --stdlib compiler flag on 10.7+. Unsupported on 10.6 and below.
     - Use sh default assignment instead of default value in macbuild.sh.
       Removes the need to redundantly specify the variable name.
     - App bundle and dmg file will be automatically removed when removing the
       client build directory. Remove redundancy from macbuild.sh.
     - Remove 'function' keyword in macbuild.sh, as it's causing undefined
       behavior according to SUS.
     - Define and implement new function 'make_boolean()' in macbuild.sh. Takes
       a pseudo-boolean value and outputs either 0 or 1. Use this function.
     - Move functions to the start of the macbuild.sh script.
     - New env var/parameter UNIVERSAL in macbuild.sh. Switches the build
       architecture to either exclusively x86_64 (UNIVERSAL=0) or both x86_64
       and x86 (UNIVERSAL=1).
     - Add usage message to macbuild.sh obtainable via -h or --help.
     - x2goclient.pro.maemo: cleanup.
       + Reorder sections so that they match x2goclient.pro.
       + Adapt to new directory structure.
       + Various whitespace fixes.
     - Move OS X-specific stuff from general section to macx section in
       x2goclient.pro.
     - Move ICON definition up before it's actually used in the macx section in
       x2goclient.pro.
     - Windows: move building into client_build subdirectory. Also needs the
       changes in buildscripts.git.
     - Windows: convert and delete the other config or build scripts. Delete
       obsolete ones.
     - Windows: correctly reference windows icon.
     - x2goclient.spec: fix builds on Fedora and related due to failing removal
       of browserplugin directory. That's non-critical.
     - onmainwindow.cpp: actually call slotTunnelOk(int), do not generate a run
       time error by calling the non-existent function slotTunnelOk().
       Fixes: #804.
     - onmainwindow.cpp: clarify message regarding missing SSH daemon host
       keys. Fixes: #793.
     - non_modal_messagebox.{cpp,h}: Add new Non_Modal_MessageBox class for
       non-modal message boxes.
     - onmainwindow.cpp: use Non_Modal_MessageBox::critical function to display
       errors relating to missing sshd host keys. Fixes: #794.
     - onmainwindow.cpp: also make the message about a non-running sshd
       non-modal.
     - {x2goclient.pro,res/osxbundle/{Info.plist,postbuild.sh}}:
       + Add new postbuild script to set the correct version in the processed
         Info.plist output file.
       + Use this script in x2goclient.pro as QMAKE_POST_LINK command.
       + Move Icon copying into that script.
       + Define version in x2goclient.pro.
     - onmainwindow.cpp: consolidate Windows and non-Windows sshd startup error
       message.
     - onmainwindow.cpp: typo fix (authoized_keys.)
     - onmainwindow.cpp: stop exporting directories (Printing, File Sharing) on
       sshd error.
     - onmainwindow.cpp: fix session icon not being displayed as tray icon
       (missed legacy resource URI wrapper call.)
     - configdialog.cpp: update XQuartz outdated version info message and
       links. Add MacPorts reference.
     - configdialog.cpp: reformat code, add MacPorts and XQuartz references,
       URL's and installation instructions, don't show outdated version warning
       when no XQuartz server is installed. Fixes: #792.
     - x2goutils.{h,cpp}: use QString references.
     - x2goutils.{h,cpp}: add new helper function show_RichText_WarningMsgBox.
     - configdialog.cpp: use new helper function show_RichText_WarningMsgBox to
       show proper errors. Format as HTML. Use hyperlinks. Rephrase XQuartz
       warning messages.
     - configdialog.cpp: return empty strings as paths to the XQuartz
       application if no valid one could be found in order to show the proper
       error message.
     - configdialog.cpp: rephrase another error message, use the new helper and
       reformat code.
     - onmainwindow.{cpp,h}: make slotTunnelOk parameter optional and use the
       non-parameter call for the QSingleShotTimer::timeout() signal.
     - x2goutils.{h,cpp}: split up show_RichText_WarningMsgBox() into the
       aforementioned function and a new convert_to_rich_text() helper function.
     - non_modal_messagebox.{h,cpp}: add new Non_Modal_MessageBox::critical()
       overloaded functions to be able to use informative text and a (forceful,
       if requested) conversion to rich text.
     - onmainwindow.cpp: prettify non-running sshd error message.
     - onmainwindow.cpp: prettify non-available host key error message.
     - onmainwindow.cpp: also use usermode sshd on OS X, if no global daemon is
       running.
     - onmainwindow.cpp: on OS X, specify sshd's PID file location in its
       server config.
     - onmainwindow.cpp: wait 3 seconds before checking sshd startup state to
       allow it to come up.
     - onmainwindow.cpp: adapt SSH host key warning message to new usermode
       sshd possibilities.
     - configdialog.cpp: make XQuartz detection algorithm QStringList-based and
       add MacPorts location.
     - onmainwindow.cpp: do not define Ctrl+Q two times. Made it unusable on
       Linux and Windows. (Fixes: #830).
     - onmainwindow:cpp: correctly pass escaped single quote when writing
       remote xinerama config file. Post-fixup for #797.
     - {onmainwindow.cpp,README.i18n}: fix localization -- resource strings
       were not correctly updated. Fixes: #828.
     - onmainwindow.cpp: quote commands for generating pulse-client.conf
       correctly, add more quotes and use absolute file path for pulse cookie.
     - version.h: add include guard.
     - help.{cpp,h}: add skeleton for new help system.
     - help.{cpp,h}: add sanitizing helpers.
     - help.cpp: populate pretty_print: fetch max length of params.
     - help.cpp: get terminal window sizes on UNIX-based and Windows operating
       systems.
     - help.cpp: complete pretty printer function.
     - help.cpp: "copy" old command line parameters.
     - help.cpp: document broker options. Fixes: #851.
     - help.cpp: actually output the help message.
     - help.{cpp,h}: also pass the help message on (for display in graphical
       mode.)
     - x2goclient.pro{,.maemo}: add new help.{cpp,h} files.
     - onmainwindow.cpp: replace old help system with new one.
     - {{onmainwindow,help}.cpp},help.h}: fix misc. build errors.
     - help.h: fix run time error by actually giving QTextStream a "device" to
       write to.
     - help.cpp: clear current string if completely written onto one line.
     - help.cpp: enable debugging for pretty_print(). --debug must be supplied
       before --help for this to work.
     - help.cpp: fix splitting algorithm to step over a space character, but
       include hyphens correctly into the current line.
     - help.cpp: don't let qCritical() add even more spaces or quotes around
       the help message.
     - help.cpp: add support for newlines within descriptions.
     - help.cpp: use new newline feature for some options.
     - help.cpp: trying to split at hyphens was a bad idea. Remove that part.
     - help.cpp: fix a compile warning (by including winsock2.h) and error
       (caused by a typo) on Windows.
     - help.cpp: hardcode indentation value to 2 (for the first spaces) +
       maximum length of parameters + 4 (for the trailing 4 spaces).
       Calculations via terminal_cols and remaining do not work, if
       terminal_cols is unknown.
     - x2goutils.{cpp,h}: implement new git_changelog_extract_commit_sha
       helper, extracting the most recent commit shasum from a git changelog
       string.
     - help.cpp: use new git_changelog_extract_commit_sha() helper while
       building the help prelude.
     - helpdialog.cpp: change to monospaced font.
     - helpdialog.cpp: use QT_VERSION macro to select either a monospaced or
       typewriter font (Qt < 4.7.0 only supports TypeWriter.)
     - x2goutils.{cpp,h}: add new font_is_monospaced() helper.
     - helpdialog.cpp: try harder to set a monospaced font.
     - helpdialog.cpp: lower font size to have more space for text.
     - ui/helpdialog.ui: almost double the window size.
     - help.cpp: typo fix for --git-info.
     - help.{cpp,h}: provide string splitting logic as separate
       split_long_line() function. Use this in pretty_print().
     - help.cpp: simplify pretty_print() and make it also split lines for
       non-terminal output or when the terminal width is unknown.
     - help.{cpp,h}: add a boolean terminal_output parameter to the
       pretty_print() function family. Controls terminal width auto-detection
       and automatic printing to stderr.
     - onmainwindow.cpp: don't let a potential terminal affect the help string
       shown in the GUI.
     - help.h: lower default splitting length to 100 characters.
     - onmainwindow.cpp: fix up pulse config file generation and
       PULSE_CLIENTCONFIG setting once more.
     - {macbuild,res/osxbundle/postbuild}.sh: add support for git information
       if not building from a tag. Also includes build date.
     - {{configdialog,onmainwindow}.cpp,x2goutils.{cpp,h}}: new helper
       functions show_XQuartz_not_found_error(), show_XQuartz_start_error() and
       show_XQuartz_generic_error(). The first two are calling the latter one.
       Replace previous messages in configdialog.cpp and onmainwindow.cpp with
       the helpers, because they are supposed to pop up a dialog showing almost
       the same message.
     - x2goutils.cpp: fix compile error. tr () is a member of QObject and must
       be explicitly marked as such in a free function.
     - {configdialog.{cpp,h},onmainwindow.cpp}: miscellaneous typo fixes - no
       functional changes.
     - onmainwindow.cpp: whitespace changes to installTranslator() only.
     - onmainwindow.cpp: correctly let Qt fetch the UI display language for Qt
       4.8.0 and higher. The old "compat" behavior is retained for older
       versions of Qt, which do not have the semantics of a UI display
       language. Fixes: #845.
     - config_win.bat: enable release by default, fetch command line parameter
       and compare against debug. Enable debug and console features in that
       case.
     - onmainwindow.{cpp,h}: follow-up to last translation fix. Actually handle
       English locales correctly and don't duplicate code too much.
     - onmainwindow.{cpp,h}: make new get_translator() function static. Correct
       typo in implementation.
     - onmainwindow.h: include used types/headers.
     - onmainwindow.cpp: correctly call QLocale::uiLanguages ().
     - onmainwindow.cpp: copy strings before manipulating them.
     - onmainwindow.h: make get_translator() const. Does not change any state.
     - onmainwindow.cpp: fix compile error triggered by a missing
       parenthesis/typo.
     - onmainwindow.cpp: workaround https://bugreports.qt.io/browse/QTBUG-25973.
     - onmainwindow.h: revert const-qualifier for get_translator(). It's static
       and can't have any cv-qualifier.
     - copy-deps-win32.bat: actually let xcopy error correctly.
     - general: improve debug output and error messages.
