This is of course to avoid buffer overruns
The remaining strcpy instance in the module needs to be audited for

MIB-II: use strlcpy when copying interface names to .ifr_name
.ifra_name is assumed to be NUL terminated; using strlcpy(3)
ensures that it's indeed NUL terminated whereas strncpy does
not.

MIB-II: use strlcpy when copying interface names to .ifr_name
.ifra_name is assumed to be NUL terminated; using strlcpy(3)
ensures that it's indeed NUL terminated whereas strncpy does
not.
Tested and verified as follows with a combination of ifconfig,
snmpget, and snmpset:
% ifconfig create lo1 127.0.0.2/8
% SNMPARGS="-v 3 -n '' -u bsnmp -A bsnmptest -l authPriv -a sha -x des -X bsnmptest localhost"
% snmpget $SNMPARGS IF-MIB::ifAdminStatus.4
IF-MIB::ifAdminStatus.4 = INTEGER: up(1)
% snmpset $SNMPARGS IF-MIB::ifAdminStatus.4 i 2
IF-MIB::ifAdminStatus.4 = INTEGER: down(2)
% snmpget $SNMPARGS IF-MIB::ifAdminStatus.4
IF-MIB::ifAdminStatus.4 = INTEGER: down(2)
% snmpset $SNMPARGS IF-MIB::ifAdminStatus.4 i 1
IF-MIB::ifAdminStatus.4 = INTEGER: up(1)
% snmpget $SNMPARGS IF-MIB::ifAdminStatus.4
IF-MIB::ifAdminStatus.4 = INTEGER: up(1)
