When using route-to (or reply-to) pf sends the packet directly to the output interface. If that interface doesn't support checksum offloading the checksum has to be calculated in software. That was already done in the IPv4 case, but not for the IPv6 case. As a result we'd emit packets with pseudo-header checksums (i.e. incorrect checksums). This issue was exposed by the changes in r289316 when pf stopped performing full checksum calculations for all packets. Submitted by: Luoqi Chen MFC after: 1 week |
