That is still the old code.

The error message is complaining about this line in libopeniscsiusr/sysfs.c:

> [   44s] sysfs.c: In function '_iscsi_host_id_of_session':
> [   44s] sysfs.c:326:48: error: '/iscsi_host/' directive output may be truncated writing 12 bytes into a region of size between 1 and 4096 [-Werror=format-truncation=]

But that code has been changed is now looks like:

>         strncpy(sys_scsi_host_dir_path, sys_dev_path, PATH_MAX);
>         strncat(sys_scsi_host_dir_path, iscsi_host_dir_str,
>                 PATH_MAX - iscsi_host_dir_strlen);

So you need to trigger a rebuild?
