Summary: lttng-tools and lttng-babeltrace executables contain
bad RPATH pointing to host machine
Product: buildroot

OS/Version: Linux
Status: NEW
Severity: normal

The lttng-tools and lttng-babeltrace executables contain bad RPATHs pointing to
the buildroot output/build directory. This happens with lttng-tools versions
2.6.0 and 2.7.0-rc1, as well as with lttng-babeltrace.
objdump -p shows the following:
RPATH
/workspace/sw/bhshelto/buildroot/buildroot/output/build/lttng-tools-2.7.0-rc1/src/lib/lttng-ctl/.libs:/workspace/sw/bhshelto/buildroot/buildroot/output/host/usr/aarch64-buildroot-linux-gnu/sysroot/usr/lib:/workspace/sw/bhshelto/buildroot/buildroot/output/build/liburcu-0.8.7/.libs
This is a problem for us because /workspace is an NFS mount that we use for
development builds, and we also mount it on our embedded targets. When
/workspace is not mounted on the embedded target, the lttng utilities run fine,
since the RPATH does not match anything. However, if I mount /workspace, I see
the following:
[root at buildroot cli]# lttng stop
lttng: error while loading shared libraries:
/workspace/sw/bhshelto/buildroot/buildroot/output/build/lttng-tools-2.7.0-rc1/src/lib/lttng-ctl/.libs/liblttng-ctl.so.0:
file too short
[root at buildroot cli]# cd
[root at buildroot ~]# umount /workspace
[root at buildroot ~]# lttng stop
Waiting for data availability
Tracing stopped for session my-session
When I use patchelf to remove the RPATH, everything works as expected.
