Description Arvid Requate

2012-02-07 12:48:43 CET

Der an Bug 25958 Comment 5 angehängte Patche  aktivieren Compiler-Optimierungen (-O2) für den Build von Listener und Notifier. Aktuell sind sie nicht aktiviert. Außerdem wird -fstack-protector --param=ssp-buffer-size=4 aktiviert, mit dem der Prozess bei einem Überlauf kontrolliert beendet wird. (flags.patch)

Außerdem sollten wir D_FORTIFY_SOURCE aktivieren; dadurch ersetzt der Compiler Speicherzugriffe mit konstanter Länge. fortify.patch, open.patch). Die Patches hängen an Bug 25958 Comment 6 und 7

r72517 | Bug #26039 UDL: Fix compilation erros
 I had to fix UDL anyway to fix some compilation problems with gcc from UCS-4.2, so I fixed it.

Package: univention-directory-listener
Version: 11.0.0-1A~4.2.0.201609121259
Branch: ucs_4.2-0

Verified, defined during built time (man dpkg-buildflags):

* -O2 -fstack-protector-strong
* -D_FORTIFY_SOURCE=2

Additional return code checks in the source are ok too.

I've added a changelog entry.
