69 | * Based on ipv6_skip_exthdr() in net/ipv6/exthdr.c | |
70 | * | |
71 | * This function parses (probably truncated) exthdr set "hdr" | |
72 | * of length "len". "nexthdrp" initially points to some place, | |
73 | * where type of the first header can be found. | |
74 | * | |
75 | * It skips all well-known exthdrs, and returns pointer to the start | |
76 | * of unparsable area i.e. the first header with unknown type. | |
77 | * if success, *nexthdr is updated by type/protocol of this header. | |
78 | * | |
79 | * NOTES: - it may return pointer pointing beyond end of packet, | |
80 | * if the last recognized header is truncated in the middle. | |
81 | * - if packet is truncated, so that all parsed headers are skipped, | |
82 | * it returns -1. | |
83 | * - if packet is fragmented, return pointer of the fragment header. | |
84 | * - ESP is unparsable for now and considered like | |
85 | * normal payload protocol. | |
86 | * - Note also special handling of AUTH header. Thanks to IPsec wizards. | |
