From 3a75f9f2f9ad19bb9a0f566373ae91d8f09db85e Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 21 Jun 2022 15:48:29 +0200 Subject: efi: vars: Use locking version to iterate over efivars linked lists Both efivars and efivarfs uses __efivar_entry_iter() to go over the linked list that shadows the list of EFI variables held by the firmware, but fail to call the begin/end helpers that are documented as a prerequisite. So switch to the proper version, which is efivar_entry_iter(). Given that in both cases, efivar_entry_remove() is invoked with the lock held already, don't take the lock there anymore.
