From b718342a7fbaa2dff5fefc31988c07af8c6cbc21 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 27 Apr 2026 12:58:56 -0700 Subject: net: psp: require admin permission for dev-set and key-rotate The dev-set and key-rotate netlink operations modify shared device state (PSP version configuration and cryptographic key material, respectively) but do not require CAP_NET_ADMIN. The only access control is psp_dev_check_access() which merely verifies netns membership.
