This is a buggy. If both are set, now, this makes such ELFs be discarded: $ RPM_BUILD_ROOT=/usr /usr/lib/rpm/verify-elf /usr/lib64/libdw-0.155.so section [18] '.tbss': alloc flag set but section not in any loaded segment verify-elf: ERROR: /usr/lib64/libdw-0.155.so: eu-elflint failed verify-elf: ERROR: /usr/lib64/libdw-0.155.so: RPATH contains a non-ascii entry: /usr/lib64/elfutils /usr/lib64/elfutils verify-elf: ERROR: /usr/lib64/libdw-0.155.so: RPATH contains illegal entry "/usr": /usr/lib64/elfutils /usr/lib64/elfutils $ objdump -p /usr/lib64/libdw-0.155.so | fgrep PATH RPATH /usr/lib64/elfutils RUNPATH /usr/lib64/elfutils $ rpm -qf /usr/lib64/libdw-0.155.so elfutils-0.155-alt2 $ (This is an old version of elfutils, just used as an example here.) Hopefully, this is a very rare case that both are set in Sisyphus. This case should be error_strict. (I have overlooked that in verify_rpath(), unlike in other 3 cses where rpath is analyzed, it is not split into lines by : first.) BTW, here is an example of the output of LD_DEBUG=libs , which I'd like to use in a further enhancement to get the standard search path (and to prefix it with RPM_BUILD_ROOT) -- to be as close to the real behavior of the runtime linker as possible. (As for verify_rpath()'s check for the presence of standard patsh in rpath, it should probably take into account not only the arch-specific set of search paths, but all possible ones as looked into by ldconfig, because their presence may signal an error, too.) $ LD_TRACE_LOADED_OBJECTS=1 LD_DEBUG=libs /lib64/ld-linux-x86-64.so.2 --inhibit-cache /usr/lib64/libdw-0.155.so 9473: find library=libelf.so.1 [0]; searching 9473: search path=/usr/lib64/elfutils/tls/x86_64:/usr/lib64/elfutils/tls:/usr/lib64/elfutils/x86_64:/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/tls/x86_64/libelf.so.1 9473: trying file=/usr/lib64/elfutils/tls/libelf.so.1 9473: trying file=/usr/lib64/elfutils/x86_64/libelf.so.1 9473: trying file=/usr/lib64/elfutils/libelf.so.1 9473: search path=/lib64/tls/x86_64:/lib64/tls:/lib64/x86_64:/lib64:/usr/lib64/tls/x86_64:/usr/lib64/tls:/usr/lib64/x86_64:/usr/lib64 (system search path) 9473: trying file=/lib64/tls/x86_64/libelf.so.1 9473: trying file=/lib64/tls/libelf.so.1 9473: trying file=/lib64/x86_64/libelf.so.1 9473: trying file=/lib64/libelf.so.1 9473: trying file=/usr/lib64/tls/x86_64/libelf.so.1 9473: trying file=/usr/lib64/tls/libelf.so.1 9473: trying file=/usr/lib64/x86_64/libelf.so.1 9473: trying file=/usr/lib64/libelf.so.1 9473: 9473: find library=libdl.so.2 [0]; searching 9473: search path=/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/libdl.so.2 9473: search path=/lib64:/usr/lib64 (system search path) 9473: trying file=/lib64/libdl.so.2 9473: 9473: find library=liblzma.so.5 [0]; searching 9473: search path=/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/liblzma.so.5 9473: search path=/lib64:/usr/lib64 (system search path) 9473: trying file=/lib64/liblzma.so.5 9473: 9473: find library=libbz2.so.1 [0]; searching 9473: search path=/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/libbz2.so.1 9473: search path=/lib64:/usr/lib64 (system search path) 9473: trying file=/lib64/libbz2.so.1 9473: 9473: find library=libz.so.1 [0]; searching 9473: search path=/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/libz.so.1 9473: search path=/lib64:/usr/lib64 (system search path) 9473: trying file=/lib64/libz.so.1 9473: 9473: find library=libgcc_s.so.1 [0]; searching 9473: search path=/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/libgcc_s.so.1 9473: search path=/lib64:/usr/lib64 (system search path) 9473: trying file=/lib64/libgcc_s.so.1 9473: 9473: find library=libc.so.6 [0]; searching 9473: search path=/usr/lib64/elfutils (RUNPATH from file /usr/lib64/libdw-0.155.so) 9473: trying file=/usr/lib64/elfutils/libc.so.6 9473: search path=/lib64:/usr/lib64 (system search path) 9473: trying file=/lib64/libc.so.6 9473: linux-vdso.so.1 (0x00007fff157fe000) libelf.so.1 => /usr/lib64/libelf.so.1 (0x0000003de3400000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003ddc800000) liblzma.so.5 => /lib64/liblzma.so.5 (0x0000003dec200000) libbz2.so.1 => /lib64/libbz2.so.1 (0x0000003df0800000) libz.so.1 => /lib64/libz.so.1 (0x0000003ddd400000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003dddc00000) libc.so.6 => /lib64/libc.so.6 (0x0000003ddc400000) /lib64/ld-linux-x86-64.so.2 (0x0000003ddc000000) $ 160326 1 imz 2016-11-30 13:25:21 +0300 $ RPM_BUILD_ROOT=/var/empty /usr/lib/rpm/verify-elf /usr/lib64/libdw-0.155.so section [18] '.tbss': alloc flag set but section not in any loaded segment verify-elf: ERROR: /usr/lib64/libdw-0.155.so: eu-elflint failed verify-elf: ERROR: /usr/lib64/libdw-0.155.so: RPATH contains a non-ascii entry: /usr/lib64/elfutils /usr/lib64/elfutils $ 160339 2 repository-robot 2016-11-30 20:07:10 +0300 rpm-4.0.4-alt100.96 -> sisyphus: * Wed Nov 30 2016 Ivan Zakharyaschev <imz@altlinux> 4.0.4-alt100.96 - verify-elf: don't confuse the initial verify_rpath() in case of two RUNPATH/RPATHs (ALT#32826).
