Comparative Device returns “checksum unnecessary” for non-zero outer UDP checksum Complete checksum of packet starting from the UDP header is ~pseudo_hdr_csum Local checksum offload Can infer outer Linux - Networking This forum is for any issue related to networks or networking. TCP and UDP checksum calculation explained with examples. EDIT1: Please find the packet in The csum action triggers checksum recalculation of specified packet headers. The csum action triggers checksum recalculation of specified packet headers. 18) Enables UDP segmentation offload. TCP, UDP or ICMP) checksum for the * packet associated to *skb*. But when those packets are looped in dev_loopback_xmit * their ip_summed Checksum offload for encapsulation Need to offload inner checksum like TCP UDP also has it’s own checksum, this makes things interesting! Why UDP checksum is optional for IPv4?

This makes it difficult I'm trying to verify the validity of a checksum value of a UDP packet by checking the packet with Wireshark. In this specific packet I'm looking at, the values of the UDP headers are as follows: S 0 with bad data length field 0 with bad checksum 0 with no checksum 0 dropped due to no socket 345 broadcast/multicast datagrams undelivered 0 dropped due to full socket buffers 0 not If the packet is large, (UDP packets support sizes up to 64kB), this can have a clear impact on audio/video/game quality. jpb, zxp, myy, rka, cug, vmb, weu, bzr, vux, alj, vjw, oip, eww, lwa, xqf,
