"No copyright" or "UNKNOWN" files should be covered by COPYING licence(LGPL v2).
Except:

kpartx/
It comes from partx(util-linux), and these files are under "GPL v2" or
"GPL v2 or later". Independent binary.


libmultipath/prioritizers/ontap.c
It's "GPL v2". But it's a plugin. ???


libmultipath/checkers/cciss_tur.c
Source says "GPL v2 or later", and:
/*
 *  This program originally derived from and inspired by
 *  Christophe Varoqui's tur.c, part of libchecker.
 */
At libmultipath/checkers/tur.c there is no licence, but it's derived from src/sg_turs.c
from sg3_utils. And this one is under "GPL v2 or later". But it's a plugin. ???


libmultipath/memory.c
libmultipath/memory.h
libmultipath/parser.c
libmultipath/parser.h
libmultipath/vector.c
libmultipath/vector.h
These comes from keepalived, and they are under "GPL v2 or later".


libmultipath/version.h:
"GPL v2 or later".


libmultipath/file.c
libmultipath/alias.c
Source says:
/*
 * significant parts of this file were taken from iscsi-bindings.c of the
 * linux-iscsi project.
And they are under "GPL v2 or later".


libmultipath/uevent.c
libmultipath/sysfs.c
These come from udev, and they are "GPL v2".


GPL code can not be mixed with LGPL code. So I guess libmultipath/ files are "GPL v2" ???


multipath/main.c
Under "GPL v2 or later". It's linked with libmultipath.so and libmpathcmd.so.
