Hi all,
Unlike the unlink path that is called from the VFS layer, we need to call d_delete() ourselves when a variable is deleted in efivarfs_file_write(). Failure to do so means we can access a stale struct efivar_entry when reading/writing the file, which can result in the following oops,
I still get an oops from Linghu Xiang's open/unlink test with this patch applied, running on OVMF. I'll investigate further..
