Fwd: btrfs-progs: libbtrfsutil is under LGPL-3.0 and statically liked into btrfs
This is https://bugs.debian.org/985400 - Forwarded message from Claudius Heine - Dear Maintainer, I looked into the licenses of the btrfs-progs project and found that the libbtrfsutils library is licensed under LGPL-3.0-or-later [1] The `copyright` file does not show this this. IANAL, but I think since `btrfs` (under GPL-2.0-only [2]) links to `libbtrfsutil` statically this might cause a license conflict. See [3]. This would be the part that might require upstream fixing. regards, Claudius [1] https://github.com/kdave/btrfs-progs/blob/master/libbtrfsutil/btrfsutil.h [2] https://github.com/kdave/btrfs-progs/blob/master/btrfs.c [3] http://gplv3.fsf.org/dd3-faq#gpl-compat-matrix
