The release binding is "patch/micro" and consolidation is "ON". The stability level of the ifconfig output with new interface flag is "Committed". Problem Definition and Proposal: --------------------------------- Today the ifconfig(1m) output does not display the promiscuous state of an underlying physical interface. The Solaris kernel has all the provisions to record the promiscuous state of the underlying physical interface in 'phyint_flags' member variable of struct phyint, but it does not expose that state using the existing (unused) IFF_PROMISC flag. Further, IFF_PROMISC is a standard flag that works on other Unix variants and we should support it for compatibility. Making IP subscribe to the DLPI DL_NOTE_PROMISC_ON/OFF_PHYS notifications and set/reset the IFF_PROMISC flag would fix the problem. With this fix the ifconfig(1m) output would have a new interface flag 'PROMISC' displayed in the output. (In fact, ifconfig already supports the flag, but hasn't yet displayed it due to a lack of kernel support.) The flag will not be set on IP virtual interfaces, such as "lo0", "ipmp0", or "vni0", as these lack underlying hardware. For example: bash-3.2# ifconfig -a bge0: flags=1004943 mtu 1500 index 2 inet 10.8.48.152 netmask ffffff80 broadcast 10.8.48.255 ether 0:3:ba:94:2f:56 bge0: flags=2000941 mtu 1500 index 2 inet6 fe80::203:baff:fe94:2f56/10 ether 0:3:ba:94:2f:56 bge0:1: flags=2080941 mtu 1500 index 2 inet6 2002:a08:39f0:3:203:baff:fe94:2f56/64 As shown above, all the IP interfaces defined on 'bge0' have PROMISC interface flag set. Interface change: Name Stability Comments PROMISC Committed ifconfig(1M) flag The ifconfig(1M) man page will be updated to document the new interface flag. The man page will say that the PROMISC flag means that the underlying hardware is in "promiscuous mode," and that the exact definition of that mode depends on the hardware in use. Virtual interfaces do not use this flag.
