Brad Fitzpatrick	c95fdb0f8a	net/packet/checksum: copy the gvisor checksum, remove the dep ... As part of making Tailscale's gvisor dependency optional for small builds, this was one of the last places left that depended on gvisor. Just copy the couple functions were were using.

Maisem Ali	f205efcf18	net/packet/checksum: fix v6 NAT ... We were copying 12 out of the 16 bytes which meant that the 1:1 NAT required would only work if the last 4 bytes happened to match between the new and old address, something that our tests accidentally had. Fix it by copying the full 16 bytes and make the tests also verify the addr and use rand addresses. Updates #9511 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	9d96e05267	net/packet: split off checksum munging into different pkg ... The current structure meant that we were embedding netstack in the tailscale CLI and in the GUIs. This removes that by isolating the checksum munging to a different pkg which is only called from `net/tstun`. Fixes #9756 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
