From 6c3eba1c5e283fd2bb1c076dbfcb47f569c3bfde Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Tue, 13 Jun 2023 15:35:32 -0700 Subject: bpf: Centralize permissions checks for all BPF map types This allows to do more centralized decisions later on, and generally makes it very explicit which maps are privileged and which are not (e.g., LRU_HASH and LRU_PERCPU_HASH, which are privileged HASH variants, as opposed to unprivileged HASH and HASH_PERCPU; now this is explicit and easy to verify).
