Are you referring to checks of the form “ip-length <= L2 length,” which happen in .../src/vnet/ip/ip[46]_input.c?

Hi I wonder that how VPP detect illegal packet length. I couldn't find in dpdk and unix/tap, ethernet, ipv4/6 source codes. Linux uses 'pskb_may_pull' function to detect wrong packets whereas VPP does not use 'vlib_buffer_pull' like functions. Why VPP does not check the length of received packets? Does It guarantee to access the packet's data which has wrong size? Thanks.
