[Libguestfs] Nbdkit old test plugins link to selinux.so.1
Hi all, the old 1.2.8 plugins checked into the source repo that are used for testing the plugin are linking to libselinux.so.1. This prevents these tests being run on distros without libselinux. (Arch Linux in my case) $ ldd tests/old-plugins/x86_64/Linux/v1.2.8/nbdkit-file-plugin.so linux-vdso.so.1 (0x00007ffde31d6000) libselinux.so.1 => not found libc.so.6 => /usr/lib/libc.so.6 (0x00007f72139ed000) The other old plugins don't require libselinux. Could the 1.2.8 plugins be replaced with ones not linking to libselinux? Thanks, Thomas

The plugins shouldn't be linked to libselinux at all (only the server should be linked, and only on platforms that have this library). We fixed this over-linking problem back in: commit 6c51add6bef8a08c99cb3e1d37ce6cb1812dba9d Author: Richard W.M. Jones <rjones at redhat.com> Date: Wed Jan 16 10:10:50 2019 +0000 build: Don't link everything, only the server, with libselinux. That in nbdkit 1.9. I had to backpork this patch to the stable-1.2 branch in order to compile a "new" old 1.2 file plugin without the over-linking: $ ldd ./plugins/file/.libs/nbdkit-file-plugin.so linux-vdso.so.1 (0x00007ffc341e9000) libc.so.6 => /lib64/libc.so.6 (0x00007f67c36ad000) /lib64/ld-linux-x86-64.so.2 (0x00007f67c38a4000) This should be fixed in: https://github.com/libguestfs/nbdkit/commit/76c59e92dc8ccbb6edc08f67ad752459d54d780e Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-top is 'top' for virtual machines.
