G." Subject: 2009/304 IP PROMISC Flag X-Mailer: VM 7.01 under Emacs 21.3.1 Status: RO Content-Length: 1892 I'm sponsoring this fast-track request for Girish Moodalbail. The timer is set to 05/22/2009. 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.) 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.

It's just that we will be on-par with other Unix variants, when it comes to supporting this standard flag. Further, all the SIOCGLIFFLAGS callers would start seeing this flag, hence forth. AFAIK, there is no way to know if underlying device is promiscuous or not, using any of the CLI utilities, today. Going forward, ifconfig(1m) is one way to do so. thanks ~Girish From Sebastien.Roy@Sun.COM Fri May 15 08:10:01 2009 Received: from dm-sfbay-02.sfbay.sun.com (dm-sfbay-02.SFBay.Sun.COM [129.146.11.31]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id n4FFA1DX015555 for ; Fri, 15 May 2009 08:10:01 -0700 (PDT) Received: from brmea-mail-4.sun.com (brmea-mail-4.Sun.COM [192.18.98.36]) by dm-sfbay-02.sfbay.sun.com (8.13.8+Sun/8.13.8/ENSMAIL,v2.2) with ESMTP id n4FFA1c0057629 for ; Fri, 15 May 2009 08:10:01 -0700 (PDT) Received: from fe-amer-10.sun.com ([192.18.109.80]) by brmea-mail-4.sun.com (8.13.6+Sun/8.12.9) with ESMTP id n4FFA1Bv015431 for ; Fri, 15 May 2009 15:10:01 GMT MIME-version: 1.0 Content-transfer-encoding: 7BIT Content-type: text/plain; CHARSET=US-ASCII Received: from conversion-daemon.mail-amer.sun.com by mail-amer.sun.com (Sun Java(tm) System Messaging Server 7u2-7.02 64bit (built Apr 16 2009)) id <0KJO00B00XFM3200@mail-amer.sun.com> for psarc-ext@sac.sfbay.sun.com; Fri, 15 May 2009 09:10:01 -0600 (MDT) Received: from [129.148.174.103] ([unknown] [129.148.174.103]) by mail-amer.sun.com (Sun Java(tm) System Messaging Server 7u2-7.02 64bit (built Apr 16 2009)) with ESMTPSA id <0KJO006WYY46OJ80@mail-amer.sun.com> for psarc-ext@sac.sfbay.sun.com; Fri, 15 May 2009 09:09:43 -0600 (MDT) Date: Fri, 15 May 2009 11:08:56 -0400 From: Sebastien Roy Subject: Re: 2009/304 IP PROMISC Flag In-reply-to: <18957.30225.816658.10165@gargle.gargle.HOWL> Sender: Sebastien.Roy@Sun.COM To: James Carlson Cc: psarc-ext@sac.sfbay.sun.com, "Girish M.

The more correct place to show whether or not a given datalink has had DL_PROMISC_PHYS enabled would be in dladm output, perhaps through a read-only link property. That, however, doesn't seem to be this case, but I thought I would note that this (to me) will be an architectural wart on Solaris that seems to only be introduced for familiarity. Given my grumbling above, I'm almost giving my "plus one", but would like some additional clarifications below.

Administrators don't really know or care about the "phyint_flags" member of struct phyint in the kernel. What they do care about is the meaning of PROMISC flag when they see it in the ifconfig output. You'll likely need to specify something more administratively meaningful in the ifconfig man page anyway, could that verbiage be specified in this case please? Does the flag have any semantics on IPMP interfaces? What about lo0; should it ever appear there?

Sure; feel free to include it there if you want. The point of this project is that not only do all of the other OSes include IFF_PROMISC and a "PROMISC" flag, but that *we* actually have them as well (because we inherited them from BSD), but they're just sitting around dormant. This project kicks them back to life. (And, if I recall correctly, SunOS 4.x _also_ included this flag. We just broke it in Solaris.) > Administrators don't really know or care about the "phyint_flags" member > of struct phyint in the kernel.

"The interface is in promiscuous mode." What "promiscuous" actually means is likely highly dependent on the actual hardware in use, and probably can't be fully explained. (Many of those old BSD interfaces seem to have been designed with Ethernet alone in mind, where the meaning for this sort of flag is obvious.) > Does the flag have any semantics on IPMP interfaces?
