Access to a BPF map from a module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi List,

I have the following problem.

I want to perform some operations on a bpf map from a loadable module. The map is instantiated elsewhere and pinned.

How do I go about to obtain the map inside the module?

bpf_map_get* functions are not exported at present so they are not available. Is there another way besides them to fetch a bpf map "by fs name" in a kernel module?

If the access limitation is intentional, may I ask what is the actual rationale behind this decision?
