Description of problem: The cyrus-sasl-lib package contains libraries. We would like them to be built with partial RELRO support as a security enhancement. Additional info: Partial RELRO requires these passed at link: -Wl,-z,relro You can fix this by patching the Makefiles to add this link flag to LDFLAGS or you might be able to simply add LDFLAGS="$LDFLAGS -Wl,-z,relro" to the configure line in the rpm's spec file. You will have to test the built packages to ensure the flags are properly passed all the way to the end of build. It does not hurt anything if the package contains applications that pick up partial relro support, too. You can test the resulting package for compliance with this program: http://people.redhat.com/sgrubb/files/rpm-chksec

Jan, there are some executables that are not yet even partial RELRO, also DSO is missing in one case. Is this expected? And if so, why pls? :: [ FAIL ] :: Check if all executables/libraries support RELRO - partial or full in cyrus-sasl (Expected 1, got 0) /usr/sbin/pluginviewer exec no no /usr/sbin/saslauthd daemon no no /usr/sbin/testsaslauthd exec no no :: [ FAIL ] :: Check if all executables/libraries support RELRO - partial or full in cyrus-sasl-lib (Expected 1, got 0) /usr/lib64/sasl2/libanonymous.so.2.0.23 library partial DSO /usr/sbin/sasldblistusers2 exec no no /usr/sbin/saslpasswd2 exec no no
Miro, only libraries should have relro! Look at bugzilla name!
