Bug ID: 272144
Summary: netlink sets ifi_type to FreeBSD if_type instead of
ARPHRD_*
Product: Base System
Version: 13.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: mi...@freebsd.org
Netlink software which uses ifi_type from ifinfomsg structure expects it to be
set to ARPHRD_* values, but currently it's getting set to if_type (from
net/if_types.h).
sys/netlink/route/iface.c:259
ifinfo->ifi_type = ifp->if_type
ifinfomsg defenition is in sys/netlink/route/interface.h
struct ifinfomsg {
...
unsigned short ifi_type /* ARPHRD_* */
...
}
Because of this software receives 0x6 (IFT_ETHER) instead of 0x1 (ARPHRD_ETHER)
for wireless interfaces and 0x18 (IFT_LOOP) instead of 772 (ARPHRD_LOOPBACK).
Same assignment happens in 14-current.
Is this difference from Linux intentional?
