Map.Iterate on a closed map is not throwing error.

[vakalapa]

Hi,

I am using v0.9.0. I closed the map accidentally and tried iterating on the map to get all keys and values.
Iterate.Err() returned nil. Is this expected ?

The map type i used is BPF_MAP_TYPE_PERCPU_HASH.

Thanks

I expected Iterate.Next to throw error if map is closed as well.

I tried to reproduce the described issue with a slightly modified version of ExampleMap_perCPU() by calling arr.Close() while iterating over the map.
After the call to arr.Close() the call of arr.Next() returns false and arr.Err() returns bad file descriptor. So I can't confirm the described issue.
Can you provide a minimal code example to reproduce the issue?
