[S] Change in libosmo-netif[master]: icmpv6: Re-license code under GPL-v2-or-later
by laforge 23 Mar '26

23 Mar '26

laforge has uploaded a new patch set (#2). ( https://gerrit.osmocom.org/c/libosmo-netif/+/42476?usp=email ) Change subject: icmpv6: Re-license code under GPL-v2-or-later ...................................................................... icmpv6: Re-license code under GPL-v2-or-later The original statement in my code from osmo-ggsn commit d46bcd236e93432c894a939f4e5810dc5e9b4974 in 2017 was worded GPLv2-only, which was due to the fact that the original OpenGGSN code is v2-only. All subsequent modifications to this code were done by either me or Pau Espin, who was doing the work under contract with sysmocom, of which I'm the managing director. Therefore, I have legal authority to re-license this file to v2-or-later.
