Commit 76350316de38 ("Handle IPv6 interfaces correctly.") added
a string copy that creates this gcc-11 error message:
> gcc-11 -O2 -g -Wall -Werror -Wextra -fvisibility=hidden -fPIC -I/usr/include/kmod -c -o idbm.o idbm.c
> idbm.c: In function _idbm_node_rec_link:

> 999 | strncpy((*node).iface.name, iface_name, ISCSI_MAX_IFACE_LEN);
> | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So copy one less character, maximum.
