https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291948 Bug ID: 291948 Summary: Stop using NetApp's OUI for generated MAC addresses Product: Base System Version: 16.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bhyve Assignee: virtualization@FreeBSD.org Reporter: michaelo@FreeBSD.org If a MAC address is not supplied for a NIC the code says: > ./usr.sbin/bhyve/net_utils.c: * The default MAC address is the standard NetApp OUI of 00-a0-98, We should stop using NetApp's OUI (see net_genmac()). The manpage says: > If mac is not specified, the MAC address is derived from a > fixed OUI and the remaining bytes from an MD5 hash of the > slot and function numbers and the device name. Since "fixed" is not specified it is implementation specific and can be changed anytime. AT least 16-CURRENT shall use 58:9C:FC. It needs to be made sure that the generated MAC address is within > ./sys/net/ieee_oui.h:#define OUI_FREEBSD_BHYVE_LOW OUI_FREEBSD(0x000001) > ./sys/net/ieee_oui.h:#define OUI_FREEBSD_BHYVE_HIGH OUI_FREEBSD(0x0fffff) -- You are receiving this mail because: You are the assignee for the bug.help
