Is there any problem with this patch? It's archived in patchwork, but still in state "new". Therefore I guess it was dropped before being considered for review. This problem precludes the implementation of a kernel selftest for TCA_FLOWER_KEY_MPLS_OPTS. Just let me know if I should respin. Thanks, William

My guess is it got auto archived :S Here is the list of all patches that are Archived as New: https://patchwork.kernel.org/project/netdevbpf/list/?state=1&archive=true Should any of these have been reviewed?

I thought some patches had magically disappeared - and some of those are in that list.

I think your patches are covered, but you should check the repo to make
sure.

This patch ("tc: flower: fix json output with mpls lse") doesn't appear in the upstream tree.

Will do, thanks.

The json output of the TCA_FLOWER_KEY_MPLS_OPTS attribute was invalid. Example: $ tc filter add dev eth0 ingress protocol mpls_uc flower mpls \ lse depth 1 label 100 \ lse depth 2 label 200 $ tc -json filter show dev eth0 ingress ...{"eth_type":"8847", " mpls":[" lse":["depth":1,"label":100], " lse":["depth":2,"label":200]]}... This is invalid as the arrays, introduced by "[", can't contain raw string:value pairs. Those must be enclosed into "{}" to form valid json ojects. Also, there are spurious whitespaces before the mpls and lse strings because of the indentation used for normal output. Fix this by putting all LSE parameters (depth, label, tc, bos and ttl) into the same json object. The "mpls" key now directly contains a list of such objects. Also, handle strings differently for normal and json output, so that json strings don't get spurious indentation whitespaces. Normal output isn't modified. The json output now looks like: $ tc -json filter show dev eth0 ingress ...{"eth_type":"8847", "mpls":[{"depth":1,"label":100}, {"depth":2,"label":200}]}...
