BPF Maps with wildcards
|
Marinos Dimolianis
Hi all, I am trying to find a way to represent wildcards in BPF Map Keys?
I could not find anything relevant to that, does anyone know anything further. Are there any efforts towards that functionality? Regards, Marinos |

The closest map is lpm (trie) map. You may want to take a look. |

Thanks for the response. LPM is actually the closest solution however I wanted a structure closer to the way TCAMs operate in which you can have wildcards also in the interim bits. I believe that something like that does not exist and I need to implement it using available structures in eBPF/XDP.
