Description

decode-ipv4.c：In function DecodeIPV4Options [line 313] Options length must be padded to 8byte boundary

According to RFC 791, the total length of the IPv4 header must be an integer multiple of 4 bytes, including the IP option field. The length of the option field can be arbitrary, but it must be aligned to a 32-bit word (4 bytes). In other words, if the length of the IP option is not a multiple of 4 bytes, you should make sure that the length of the IP header is a multiple of 4 bytes by padding.
