How to access BPF_MAP_TYPE_LRU_PERCPU_HASH in cilium ebpf?

[kawhicurry]

Iterator always return false while Lookup return error:

cpu 0: unexpected EOF

Not support yet?

That might be, the PerCPU LRU maps are kind of peculiar beasts. Feel free to open a bug report with a reproducer.

Got it. I'll prepare the example code for this first.

I try to reproduce the failing code but failed.

I'm not familiar with the ebpf map two weeks ago. I might have misunderstood the PERCPU_LRU_HASH and tried to treat it as hash map in array, so I use an array to extract the contents from hash map. I should take it as a normal hash map that return array.

Sorry for misreport that. I'll be careful next time.
