pstore/ram: Add kmsg hlen zero check to ramoops_pstore_write() If zero-length header happened in ramoops_write_kmsg_hdr(), that means we will not be able to read back dmesg record later, since it will be treated as invalid header in ramoops_pstore_read(). So we should not execute the following code but return the error. Signed-off-by: Yue Hu <huyue2@yulong.com> Signed-off-by: Kees Cook <keescook@chromium.org>
