Hello @aymericDD. Could you please explain this weird behaviour so we can provide more context for this change. |
|
When I was using a BPF_MAP_TYPE_HASH with a struct key and struct value, the map was not returned in the list of IDs. I take a look at the bpftool and I notice the ID was not re-incremented manually. |
|
I added a unit test to cover this case. I don't have a local dev environment because I have a Macbook pro M1 and vagrant with virtualbox is not supported for now with the ARM architecture. |

It retrieves the next available map ID after the given startID.

Remove custom error to reduce maintenance toil. Just return the syscall error is enough and does not ask to create custom error for each kind of syscall errors.

The startId was not a pointer, so its value was never updated for the caller of the GetMapsIDsByName function.

The
idis incremented byC.bpf_map_get_next_idso no need to define thestartIdandnextId. I encounter some weird behavior in my project when I was using map with a BPF_MAP_TYPE_HASH type.
