segmentation faults with uClibc-ng

[wbx-github]

When using a system with uClibc-ng for embedded targets with Buildroot or
Gentoo/hardened on Desktop there is a segmentation fault trying to use cryptsetup.
The reason for it is, that uClibc-ng does not support symbol versioning.

See here a workaround:

Is the combat code still required in libdm/ioctl/libdm-iface.c?

Thanks

Hi.
Please see my patch here: https://www.redhat.com/archives/dm-devel/2018-July/msg00187.html
In general after applying this patch you can compile lvm2 with --disable-symvers option, so lvm2 under uclibc will work successfully.

Issue resolved with option --with-symvers / --without-symvers based on this originating patch for upstream lvm2 2.03.12 in this commit: 1cedbaf.
