passt: Relicense to GPL 2.0, or any later version In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas. Change licensing terms to the GNU General Public License Version 2, or any later version, with written permission from all current and past contributors, namely: myself, David Gibson, Laine Stump, Andrea Bolognani, Paul Holzinger, Richard W.M.

LICENSES: Add license text files, add missing notices, fix SPDX tags SPDX tags don't replace license files. Some notices were missing and some tags were not according to the SPDX specification, too.

treewide: Add include guards ...at the moment, just for consistency with packet.h, icmp.h, tcp.h and udp.h. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> 2022-03-25 23:05:31 +00:00			`#ifndef NDP_H`

ndp: Remove unneeded eh_source parameter ndp() takes a parameter giving the ethernet source address of the packet it is to respond to, which it uses to determine the destination address to send the reply packet to. This is not necessary, because the address will always be the guest's MAC address. Even if the guest has just changed MAC address, then either tap_handler_passt() or tap_handler_pasta() - which are the only call paths leading to ndp() will have updated c->mac_guest with the new value. So, remove the parameter, and just use c->mac_guest, making it more consistent with other paths where we construct packets to send inwards.
