Alexey Kodanev 4890349d79 vti6: remove !skb->ignore_df check from vti6_xmit() ... [ Upstream commit 9f28954614 ] Before the commit d6990976af ("vti6: fix PMTU caching and reporting on xmit") '!skb->ignore_df' check was always true because the function skb_scrub_packet() was called before it, resetting ignore_df to zero. In the commit, skb_scrub_packet() was moved below, and now this check can be false for the packet, e.g. when sending it in the two fragments, this prevents successful PMTU updates in such case. The next attempts to send the packet lead to the same tx error. Moreover, vti6 initial MTU value relies on PMTU adjustments. This issue can be reproduced with the following LTP test script: udp_ipsec_vti.sh -6 -p ah -m tunnel -s 2000 Fixes: ccd740cbc6 ("vti6: Add pmtu handling to vti6_xmit.")
