Interesting... then this problem is much more serious than I thought.
Looks like in RX path the bridge sets the checksum to CHECKSUM_NONE
too:
static inline void skb_forward_csum(struct sk_buff *skb)
{
/* Unfortunately we don't support this one. Any brave souls? */
if (skb->ip_summed == CHECKSUM_COMPLETE)
skb->ip_summed = CHECKSUM_NONE;
}
I guess this is probably why Docker/Kubernetes could be affected too.
