Ahmed Abdelsalam 0cb7498f23 seg6: fix SRH processing to comply with RFC8754 ... The Segment Routing Header (SRH) which defines the SRv6 dataplane is defined in RFC8754. RFC8754 (section 4.1) defines the SR source node behavior which encapsulates packets into an outer IPv6 header and SRH. The SR source node encodes the full list of Segments that defines the packet path in the SRH. Then, the first segment from list of Segments is copied into the Destination address of the outer IPv6 header and the packet is sent to the first hop in its path towards the destination. If the Segment list has only one segment, the SR source node can omit the SRH as he only segment is added in the destination address. RFC8754 (section 4.1.1) defines the Reduced SRH, when a source does not require the entire SID list to be preserved in the SRH. A reduced SRH does not contain the first segment of the related SR Policy (the first segment is the one already in the DA of the IPv6 header), and the Last Entry field is set to n-2, where n is the number of elements in the SR Policy. RFC8754 (section 4.3.1.1) defines the SRH processing and the logic to validate the SRH (S09, S10, S11) which works for both reduced and non-reduced behaviors. This patch updates seg6_validate_srh() to validate the SRH as per RFC8754. Signed-off-by: Ahmed Abdelsalam <ahabdels@gmail.com> Signed-off-by: David S.
