Hi Stephen, I'm a bit unsure of the decorum in this particular situation. Kernel support for mpls/ip tunnels was integrated back in July of 2016. At the time, the author of that feature sent out a RFC patch for the iproute support but never followed up on subsequent code review comments.
The kernel support got merged, but the iproute support never made it in. I wanted to run some tests with these features. In the process, I tracked down the author's original patches, merged them into current iproute, and attempted to address the comments from code reviewers. I've attached an 'Original-Author' label to each commit, and have CC'd him and the code reviewer on this patch. If any part of this is improper, please let me know and I'll respin accordingly. Mostly, I wanted to close the loop here so the mpls in ip tunnel support is usable through iproute. The original threads for the 2016 patch are here: http://marc.info/?l=linux-netdev&m=146782946216005&w=2 http://marc.info/?l=linux-netdev&m=146782941615977&w=2 http://marc.info/?l=linux-netdev&m=146782947016007&w=2 http://marc.info/?l=linux-netdev&m=146782942915988&w=2 Thanks, -K Krister Johansen (3): iptunnel: document mode parameter for sit tunnels iptunnel: add support for mpls/ip to sit tunnels iptunnel: add support for mpls/ip to ipip tunnels include/utils.h | 3 +++ ip/link_iptnl.c | 30 ++++++++++++++++++++++++++---- ip/tunnel.c | 3 +++ man/man8/ip-link.8.in | 12 +++++++++++- 4 files changed, 43 insertions(+), 5 deletions(-) -- 2.7.4
