Dear all
The X2Go project is proud to announce a new release of the X2Go
component ,,nx-libs''.
New gains of this version of ,,nx-libs'' are:
o further reduction of code size by Mike Gabriel (93MB -> 41MB
uncompressed, 16MB -> 6.5MB compressed)
o ~/.x2go/config/keystrokes.cfg, /etc/x2go/keystrokes.cfg and
/etc/nxagent/keystrokes.cfg are now respected thanks to Horst Schirmeier
o security fixes for CVE-2011-2895, CVE-2011-4028, CVE-2013-4396,
CVE-2013-6462, CVE-2014-0209, CVE-2014-0210, CVE-2014-0211,
CVE-2014-8092, CVE-2014-8097, CVE-2014-8095, CVE-2014-8096,
CVE-2014-8099, CVE-2014-8100, CVE-2014-8102, CVE-2014-8101,
CVE-2014-8093, CVE-2014-8098, CVE-2015-0255 by Michael DePaulo
o Debian/Ubuntu packaging rework; libnx-x11 now split up into multiple
packages; new -dev packages; setting LD_LIBRARY_PATH now unnecessary;
new multi-arch support; new hardened support
o libraries now versioned on RPM-based distros; miscellaneous RPM fixes
o new patch naming scheme based on four digits
o other (build) bug fixes
We thank Horst Schirmeier for improving our software.

Changes:
nx-libs (3.5.0.29) RELEASED; urgency=medium
.
[ Mike Gabriel ]
* Update 0320_nxagent_configurable-keystrokes.full.patch. Fix patch
header
referring to keystrokes.cfg (plural), not keystroke.cfg.
* Allow sysadmins to manipulate nxagent's / x2goagent's rgb file by
placing
it into /etc/nxagent or /etc/x2go.
* Provide support for separate .keyboard files for nxagent/x2goagent.
* Modify 0101_nxagent_set-rgb-path.full.patch. Allow configurable rgb
files.
* Extend 0999_nxagent_unbrand-nxagent-brand-x2goagent.full.patch. Let rgb
file shipped with x2goagent supersede rgb file shipped with nxagent.
FIXME: a better approach would be to decide at runtime if to use
/etc/x2go/rgb or /etc/nxagent/rgb.
* Extend 0999_nxagent_unbrand-nxagent-brand-x2goagent.full.patch. Allow
separate .keyboard files for x2goagent and nxagent.
* Update 0600_nx-X11+nxcompext+nxcompshad_unique-libnames.full.patch.
Don't
patch files that get removed during code reduction.
* Add 0991_fix-hr-typos.full+lite.patch and 991_fix-hr-typos.full.patch.
Fix several typos in upstream code detected by lintian.
* Makefile.nx-libs: Don't allow symlinks to point into buildroot.
* Makefile.nx-libs: Install man pages via main Makefile.
* Add Description: and Author: fields to various patch headers.
* Makefile.nx-libs: Run make install for nxproxy first, then create the
wrapper script.
* Make install-lite rule in Makefile.nx-libs more predictable and not
rely on nxproxy/Makefile.in.
* Makefile.nx-libs: Fix uninstall-lite rule. The nxproxy and nxcomp
uninstallation has to be in uninstall-lite, not in uninstall-full.
* Update 1042-Do-proper-input-validation-to-fix-for-CVE-2011-2895.patch.
Fix broken comment paragraph, whitespace fix.
.
* NX code reduction efforts (from 93Mb to 41Mb):
- Drop more unused code in nx-X11/programs/Xserver/hw/. Do this in
roll-tarball.sh and in debian/rules alike.
- Stop shipping unused / very old xterm code.
- Drop nx-X11/programs/Xserver/hw/xfree86 except of four files
symlinked
to other locations in the source tree at build time.
- More source tree size reduction by analyzing what exactly of the Mesa
source code in nx-X11/extras/ is used and what not.
- Drop more unused folders from tarball release / before .deb
package build:
. nx-X11/programs/Xserver/miext/shadow/
. nx-X11/programs/Xserver/XpConfig/
. nx-X11/programs/Xserver/Xprint/
- Makefile.nx-libs: Don't install Mesa header files into DESTDIR
anymore.
- Unify source tree reduction (debian/rules vs. roll-tarball.sh)
via file/
folder lists in text files named debian/CODE-REDUCTION_*.
- Update 0991_fix-hr-typos.full.patch. Don't patch files that get
removed by
the NX code reduction effort.
- Drop 0604_nx-X11_recent-freetype-API.full.patch. Not used in
current build
process.
- Update
0600_nx-X11+nxcompext+nxcompshad_unique-libnames.full.patch. Don't
patch files matter to the NX code reduction efforts.
- Update 0031_nx-X11_parallel-make.full.patch. Don't patch
.original files
in NX code tree.
- Drop patches: 0017_nx-X11_update-autotools-helper-files.full.patch,
0018_nx-X11_update-libtool-ltmain-script.full.patch,
0019_nx-X11_expat-build-against-system-libxmltok.full.patch. They
patch
files that are not used at build time.
.
* Patch system:
- Prepend a "0" to every patch file name in debian/patches/. The patch
order is now given by a 4 digit ID. Adapt only this changelog
stanza to
this modification.
.
* Debian/Ubuntu packaging:
+ Fully rework the way nx-libs gets packaged for Debian/Ubuntu.
+ Split up libnx-x11 into individual packages.
+ Provide dbg:packages for each bin:package containing binaries.
+ Use Makefile logic to install files into DESTDIR.
+ Provide dev:packages for each lib:package individually.
+ Provide nx-x11proto-*-dev packages for all libnx-* libraries.
+ Install _all_ library files (*.so*) to /usr/lib/<triplet>/, so
no extra settings of LD_LIBRARY_PATH is necessary.
+ Add Multi-Arch support for Debian based distro versions that
support Multi-Arch.
+ Support hardened builds for nxcomp* libraries.
+ Support hardened builds for nxagent and libNX_*.so files.
+ Add debian/*.symbols files for shared nx-X11 libraries.
+ Support .symbols for 64bit and 32bit alike.
+ Provide CDBS-generated debian/copyright.in file.
.
* debian/rules:
+ Backup nxcomp/VERSION file from NoMachine before replacing it with
a symlink to debian/VERSION. Recreate the original file when cleaning
up.
+ Fix removal of unused code (that part of the code that we know of so
far). (The debian/rules file is a Makefile and Makefiles don't
understand
shell globbing with curly braces).
+ Correctly link config files (etc/rgb, etc/nxagent.keyboard,
etc/x2goagent.keyboard) before dh_auto_build.
+ Add to B-D: expat.
+ Install upstream ChangeLogs into bin:packages.
+ Remove upstream nx-libs ChangeLog during override_dh_clean.
+ Use proper quoting on build flag vars (they may contain spaces).
.
* nx-libs.spec:
+ The gpg-offline bin:package is not available in our SLE repo. We
can do
without.
+ Update .spec file to meet changes in tarball size reduction and
restructuring.
+ Use SONAME based library package naming scheme.
+ Mention NX technology in every package description.
+ Install man pages into bin:packages.
+ Make libNX_X11-6 and libXinerama1 compliant to Shared Library Policy.
+ Add Obsoletes: fields to all shared libs for marking the
non-versioned
library package (names) as obsolete.
+ Don't depend on nx-libs base package with fixed version.
+ Don't fail if removing *.a files fails due to the files being
non-present.
+ Set PREFIX=%{_prefix} USRLIBDIR=%{_libdir} SHLIBDIR=%{_libdir} at
build
time.
+ Assure that BuildRoot: is set.
+ On SLE 11.x: libX* packages are prefixed with "xorg-x11-".
+ Install "%{_libdir}/nx/bin" into nxproxy package.
.
* debian/roll-tarball.sh:
+ Install etc/ files into etc/ subfolder (rgb, nxagent.keyboard,
x2goagent.keyboard).
.
[ Horst Schirmeier ]
* Update 0320_nxagent_configurable-keystrokes.full.patch. Fix a typo that
prevented the /etc/nxagent/keystrokes.cfg file from being parsed.
(Fixes:
#741).
* Add 0321_nxagent_x2go-specific-keystroke-config.full.patch. If
nxagent is
launched as x2goagent, use X2Go-specific paths for the
keystrokes.cfg file.
(Fixes: #744).

[ Michael DePaulo ]
* Security Fixes:
- Rebase loads of X.Org patches (mainly from RHEL-5) against NX. If not
all patches from a CVE patch series appear here, then it means that
the affected file/code is not used in NX at build time.
