Source: opt Version: 3.19-1.2 Severity: important User: [email protected] Usertags: pie-bindnow-20160906 Justification: makes proftmb FTBFS with extra hardening Affects: proftmb
Dear Maintainers, During a rebuild of all packages in sid, proftmb failed to build on amd64 with patched GCC and dpkg. The root cause seems to be that libopt.a is shipped as a non-PIC library. The rebuild tested if packages are ready for a transition enabling PIE and bindnow for amd64 (and selected architectures). For more information about the changes to sid's dpkg and GCC please visit: https://wiki.debian.org/Hardening/PIEByDefaultTransition Relevant part of proftmb's build log: ... g++ -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -Wl,-z,relro -Wl,-z,now -o proftmb proftmb.o libhmm.a -lgsl -lgslcblas -lm -lopt /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/6/../../../../lib/libopt.a(opt_proc.o): relocation R_X86_64_32 against `.bss' can not be used when making a shared object; recompile with -fPIC ...
