Hi,
The README file in the audit userspace package says:
  LICENSE
  =======
  The audit daemon is released as GPL'd code. The
  audit daemon's libraries libaudit.* and libauparse.* are released
  under LGPL so that it may be linked with 3rd party software.
However don't these libraries contain code from this file
https://github.com/linux-audit/audit-userspace/blob/master/lib/strsplit.c
which states its license is GPLv2+?
