The two I'm using are ADI (now Silicom) boxes that needed some fun deep dives into BIOS versions, interrupt storms and compatible mini-PCIe cards (some just don't actually get probed!) Anyway. I ended up stumbling across one of the Silicom OEM boxes that got turned into an AT&T open compute platform box back in 2018/2019 that has an integrated Marvell 88E6190X switch hanging off of the intel X553 backplane (the ixgbe driver.) However, it wasn't supported in FreeBSD, and the instructions to get the switch up in linux were hit and miss. People had gotten the etherswitch driver patched to work, but only against pfsense plus, which has the MDIO support for ixgbe. But, I couldn't find any diffs online to implement it. So I did what I normally do, I got distracted from wifi stuff and decided to get it going. Having a working amd64 etherswitch platform would be nice for general etherswitch tinkering outside of the arm/mips/ppc world, and then no-one would have any excuses getting involved in improving it! It took a few days, but I figured it out. Here's the fun deep dive. Firstly, DPDK introduced some support for the MDIO bus being exposed on the X553, but with a couple caveats: * it started as clause 22 (which is PHYs pre-2000) diff , but it eventually got turned into a clause 45 (PHYs post-2000) diff, and they .. just deleted the clause 22 code * the MDIO support is really focused on talking MDIO to the PHYs internally inside the X550 series hardware - clause 45, fixed PHY number, etc So it wasn't enough to really bring up the marvell switch, as these all seem to want clause 22 MDIO commands. Then i went digging into the X550 and X553 datasheets. * the X550 datasheet says that it only supports clause 45 * the X553 datasheet says it supports both clause 22 and clause 45, but makes a point of (a) telling you if you need to, you should speak into intel customer engineering, and (b) deleted the MDIO registers from their register programming guide Ok, so the X553 does do Clause 22, but .. how. Then I went through the DPDK and linux driver history and lo and behold, linux actually HAS the correct mdio bus support! specifically, they have a /separate/ mdio bus driver hiding in their X550/X553 support, which: * handles both clause 22 and clause 45 IO * does the correct semaphore handshaking, since MDIO is shared between multiple ethernet MACs, hardware and firmware * exposes only one MDIO bus on the X553, as it only has a single MDIO bus shared between the 1 to 4 MACs the chipset can expose Armed with that I committed some driver sins and got it working. The in progress absolutely disgusting hack diff is attached, so it won't get lost / forgotten. Anyway, on the etherswitch side I did a bunch of cleanup to support etherswitch/miiproxy/e6000sw as modules, and fix a bunch of e6000sw bugs, and they're in -HEAD: * https://reviews.freebsd.org/D50024 to https://reviews.freebsd.org/D50031 are all cleanups * https://reviews.freebsd.org/D50044 adds the 88E6190X support But then the next fun problem - none of the ports came up. Well, I lie. Only one of them came up. I went digging into the PHY registers and found that the marvell gige PHY code didn't actually power up the PHY if it was powered down, so I fixed that too: * https://reviews.freebsd.org/D50045 Then with some hints, I could see and use all of the switch ports on the AT&T ATT-150 CPE device: hint.mdio.0.at="ix0" hint.e6000sw.0.addr="0x10" hint.e6000sw.0.port0disabled="1" hint.e6000sw.0.is6190x=1 hint.e6000sw.0.port9cpu=1 hint.e6000sw.0.port10cpu=1 hint.e6000sw.0.port9speed=2500 hint.e6000sw.0.port10speed=2500 Then, I also acquired a wireguard M270 box, as it also apprently has a marvell switch attached to an X553 backplane, and none of the ethernet ports work at all out of the box. The above hints worked on that too - with addr set to "0x0" instead of "0x10". So, now i have two Atom C3558 boxes w/ X553 2.5gbit backplane ports hooked into an 8 port marvell gige switch working on -HEAD (save the ixgbe mdio diff that I attached; I'll sort that out soon).

i'm not sure what. are you familiar with the sysctl net.add_addr_allfibs, and if so, how was it set when you were testing this? i believe to get this to work (in particul= ar, to add the correct routes) you need to set it to 0. net.inet6.ip6.rfc6204w3 may also be relevant as it seems something about th= is causes the kernel to send NDs from the GUA instead of the LLA. --=20 You are receiving

Please consider epair(4) to be a kind of linking devi= ce, a patchcord usually plugged between different vnet(9) contexts. In epair(4)= one can read: "epair =E2=80=93 A pair of virtual back-to-back connected Ethernet interfaces". But your experimentation looks reasonable and can be successful if both endpoints of the epair(4) device will belong to the same fib. So, please try this approach, it should work: ifconfig epair128a destroy sysctl net.fibs=3D129 ifconfig epair128 create fib 128 ifconfig epair128a inet6 fcff::a/64 ifconfig epair128b inet6 fcff::b/64 fib 128 setfib 128 ping6 -c 3 fcff::a setfib 128 ping6 -c 3 fcff::b --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Thu May 1 13:13:30 2025 X-Original-To: freebsd-net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4ZpDyf3169z5v91F for ;

Without this patch, mountd failed to recognize that a network/host(s) had changed, if there was no other change to the exports line. As such, the change of network/hosts(s) did not take effect until the mountd daemon was (re)started. This patch fixes the code so that it checks for changes in the network/host(s) list for an exports line.

Interface epair (4) will probably not work correctly if one endpoint is in FIB different then another endpoint, at least it has neither been tested nor proven to work passing the traffic between FIBs, since its = main purpose is interconnecting different VNETs. Perhaps adding the requested feature is feasible, but I am not the one to judge here. If your use case requires creating connections between different FIBs, maybe you can use if_bridge (4) to bind them. It should work, though I have not tested it. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sat May 3 17:25:23 2025 X-Original-To: freebsd-net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4ZqZSL25NKz5vdcr for ; Sat, 03 May 2025 17:25:38 +0000 (UTC) (envelope-from emss@mailbox.org) Received: from mout-p-103.mailbox.org (mout-p-103.mailbox.org [IPv6:2001:67c:2050:0:465::103]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 4ZqZSJ1jBJz3qJd for ; Sat, 03 May 2025 17:25:36 +0000 (UTC) (envelope-from emss@mailbox.org) Authentication-Results: mx1.freebsd.org; dkim=pass header.d=mailbox.org header.s=mail20150812 header.b=kllZUwnW; spf=pass (mx1.freebsd.org: domain of emss@mailbox.org designates 2001:67c:2050:0:465::103 as permitted sender) smtp.mailfrom=emss@mailbox.org; dmarc=pass (policy=reject) header.from=mailbox.org Received: from smtp202.mailbox.org (smtp202.mailbox.org [IPv6:2001:67c:2050:b231:465::202]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (No client certificate requested) by mout-p-103.mailbox.org (Postfix) with ESMTPS id 4ZqZS629Tzz9sFm; Sat, 3 May 2025 19:25:26 +0200 (CEST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=mailbox.org; s=mail20150812; t=1746293126; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=WNhje6XD3vd9TUxKLrA8saJjflyvCUliakao5Ge5Ui0=; b=kllZUwnWshu+3i0UimpdS/yFhZpNYINO7A+sumNhpazDiEB1mV4WEJGq50ZF5B8SvLLtDF jaidjPSiex1dyXiMVf4zKNtsNQnIKDEtQLKqyI3tsSRoXRc+om8D9fRZnKL02ckpvhAB2F qeqwQnAotEJqLa2BV93k8Ut0X8pSXUnI7BjjPfv2QRuPEqBCug0aU2AZ+SWIH6V7HrIGD8 vkJTUpmCuZk2UZu/ispcySfvWnJGAg8z/DSD7x/rvn6ZcE97MdtauFrZeWb+D9ExOgiunh OyzYeAnN0074a/VZrenlWqBb7Tr7Th7mpiHj93GB4KYpLQeCQFp1DkYDaAfGsg== From: =?utf-8?Q?=C3=89ric_Masson?= To: Roy Marples Cc: "Eugene Pereviazko" , "freebsd-net" Subject: Re: rtadvd(8) How to IPv6 tokenize interface identifier In-Reply-To: <195299cfe41.d7a8e8731186.6219551516433988607@marples.name> (Roy Marples's message of "Fri, 21 Feb 2025 17:45:09 +0000") References: <20250221075300.4466057d@thor.sb211.local> <195299cfe41.d7a8e8731186.6219551516433988607@marples.name> X-Operating-System: FreeBSD 14.3-STABLE amd64 Date: Sat, 03 May 2025 19:25:23 +0200 Message-ID: <86ecx5y5bw.fsf@one-11.fr.eu.org> List-Id: Networking and TCP/IP with FreeBSD List-Archive: https://lists.freebsd.org/archives/freebsd-net List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-net@FreeBSD.org MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable X-MBO-RS-ID: e949294e4ea0f61438e X-MBO-RS-META: n7mdcba98x4bfxfiowpm3se1ftizuwip X-Rspamd-Queue-Id: 4ZqZSJ1jBJz3qJd X-Spamd-Bar: ---- X-Spamd-Result: default: False [-4.14 / 15.00]; NEURAL_HAM_MEDIUM(-1.00)[-0.999]; NEURAL_HAM_SHORT(-1.00)[-0.998]; NEURAL_HAM_LONG(-0.94)[-0.944]; DMARC_POLICY_ALLOW(-0.50)[mailbox.org,reject]; R_SPF_ALLOW(-0.20)[+ip6:2001:67c:2050::/48]; R_DKIM_ALLOW(-0.20)[mailbox.org:s=mail20150812]; RCVD_IN_DNSWL_LOW(-0.20)[2001:67c:2050:0:465::103:from,2001:67c:2050:b231:465::202:received]; MIME_GOOD(-0.10)[text/plain]; ASN(0.00)[asn:199118, ipnet:2001:67c:2050::/48, country:DE]; RCVD_COUNT_ONE(0.00)[1]; DWL_DNSWL_NONE(0.00)[mailbox.org:dkim]; MIME_TRACE(0.00)[0:+]; MISSING_XM_UA(0.00)[]; ARC_NA(0.00)[]; FROM_EQ_ENVFROM(0.00)[]; FROM_HAS_DN(0.00)[]; TO_MATCH_ENVRCPT_SOME(0.00)[]; RCVD_TLS_ALL(0.00)[]; TO_DN_ALL(0.00)[]; RCPT_COUNT_THREE(0.00)[3]; MLMMJ_DEST(0.00)[freebsd-net@freebsd.org]; DKIM_TRACE(0.00)[mailbox.org:+] Roy Marples writes: Hi Roy > As Eugene said, you can use dhcpcd in ports with the slaac directive like= so > > interface bge0 > slaac token ::dead:beef > > Then you get ::dead:beef appended to each autoconf address from the RA. > You could use ::1 for your token which should meet your needs as above. Quite handy. Is there any way to specify multiple tokens, please? The goal would be to replace rc.conf's ifconfig aliases and automatically use the prefixes advertised to add a set of addresses. I've tried declaring suffixes on the same configuration line the following way : slaac token ::1 ::dead:beef ::ace:cafe Or using multiple lines : slaac token ::1 slaac token ::dead:beef slaac token ::ace:cafe First uses ::1 only & second uses ::ace:cafe (seems expected after a glance at if-options.c code) BR =C3=89ric From nobody Sun May 4 01:07:15 2025 X-Original-To: net@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Zqmj11vxpz5tyNG for ; Sun, 04 May 2025 01:07:17 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R11" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4Zqmj06Px3z41v5 for ; Sun, 04 May 2025 01:07:16 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1746320836; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=8M04r1Wc2e2hRSD8svhoMFmXk4x3aNlvnJBs2M5J2oo=; b=jjQNTY79dWFEGpJrZF9CkpGXBuWNRA6KLTkd6fNOf5XCTZF2d3idOynPbDduP5Ijz9/Jdc HA3wITn4I+MBO5mHV+93uT7JM4YFvIie0k6QJzTfuR6RaBlxS56MdvbwjlaQIx+TNxdk42 uhNTE71CRqFG71XC5JO3HLpUsQCV69KaHL0B9EjpfNsQsiDhVaWEk8biA3bgO3PRlgGcbw H1MC55Dytlol9pOV/vzqG1dDa8V7jJJ9KLz2FVqwF0qWDA2BN9wRoVWiASVbJRpipJk/b2 Ows4xyNHSmB+P20khKUigNCK4MBOXA1FVXHWdTeLWVAIMO9rFVCWayLOUucz6g== ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1746320836; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=8M04r1Wc2e2hRSD8svhoMFmXk4x3aNlvnJBs2M5J2oo=; b=LXKTpr/L4TpRtuvX6JmrZYklYjLAgVQ6Y81L6Q8ShkJa0oIGpM+fX6yFNMlGrnoZp4NDhf +z2GP3ejJ7OWyLqYIDoVxQrHUIuIAKaYlYnwCRqqxzSS3b3kguzWvHRcC4oTDDyFNw513s V+yg7qYKZeZJiYuYBg/I742nq/psrvNZkpgDdE49cLP3adPpq4sz3c8jnDIKJ6wo22dOxA l6a7D0eiQyiIU7s5it4+PQQ66pkg/o44V659tUNQqsG5lc8+aFSo6wF9UXuwBOL46uruRP ju+Cq3oeBz/Degw7Yqfbd/00rzrVCzZ21U0bRkqLysndjDhpf4o+gBlNiLfJRw== ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1746320836; a=rsa-sha256; cv=none; b=hlzGePDPaB+N4KZS5PonwlVMV9RaAuVr2bMD0nuJ+10p9kUlqX7+q64mLCSpm7bGGz9OTS 4zm///HqhQ4mQDZ+e9f5T5jzfZQ9Gw/beP51OmWBBYGzRBt0er2s3AHoSvuJk3Z8n0I+WO 0mojij08G3puWndQOe25Dfk9dU3kcplIPjm09jE30M0TJxVn/E2+oYUzoLkQaKTcpTEpcB dUZwxU48RQdwsJfQHA1J3u8YbghbEnlST1vhURRVs+FsSFYb/vUUAC/dc8s3LBhbTr/gIt iFwNwcoO01KmQJSPuHHi8pGvJHWwUqVl+jPFmTB5G7v1DBzpFzN6zA+u/TiY2Q== ARC-Authentication-Results: i=1; mx1.freebsd.org; none Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4Zqmj05WYmz160X for ; Sun, 04 May 2025 01:07:16 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 54417GGY026911 for ; Sun, 4 May 2025 01:07:16 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from bugzilla@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 54417GNq026910 for net@FreeBSD.org; Sun, 4 May 2025 01:07:16 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: bugzilla set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: net@FreeBSD.org Subject: [Bug 286260] NFS: sharing only for IPv6 subnet fails Date: Sun, 04 May 2025 01:07:15 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: bin X-Bugzilla-Version: 14.3-STABLE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: commit-hook@FreeBSD.org X-Bugzilla-Status: In Progress X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: rmacklem@FreeBSD.org X-Bugzilla-Flags: mfc-stable14? mfc-stable13?

Without this patch, mountd failed to recognize that a network/host(s) had changed, if there was no other change to the exports line.

Without this patch, mountd failed to recognize that a network/host(s) had changed, if there was no other change to the exports line.

We have been running the FreeBSD = stack for some time under QNX and have just recently run into an issue = with this race condition.

Anyway, on the etherswitch side I did a bunch of cleanup to support e= therswitch/miiproxy/e6000sw as modules, and fix a bunch of e6000sw bugs, an= d they're in -HEAD:

* https://reviews.f= reebsd.org/D50044 adds the 88E6190X support

Those are in -HEAD now!

But then the= next fun problem - none of the ports came up. Well, I lie. Only one of the= m came up. I went digging into the PHY registers and found that the marvell= gige PHY code didn't actually power up the PHY if it was powered down,= so I fixed that too:


<= div>=C2=A0


hint.mdio.0.at= =3D"ix0"
hint.e6000sw.0.addr=3D"0x10"
= hint.e6000sw.0.port0disabled=3D"1"
hint.e6000sw.0.is619= 0x=3D1
hint.e6000sw.0.port9cpu=3D1
hint.e6000sw.0.port10cpu=3D1
hi= nt.e6000sw.0.port9speed=3D2500
hint.e6000sw.0.port10speed=3D2500

Then, I also acquired a wireguard M270 box, as it also ap= prently has a marvell switch attached to an X553 backplane, and none of the= ethernet ports work at all out of the box.
The above hints worke= d on that too - with addr set to "0x0" instead of "0x10"= ;.

So, now i have two Atom C3558 boxes w/ X553 2.5= gbit backplane ports hooked into an 8 port marvell gige switch working on -= HEAD (save the ixgbe mdio diff that I attached; I'll sort that out soon= ). All it took was like $250 in hardware, staring at intel documentation an= d linux/dpdk driver code, and three evenings thinking to myself "surel= y this can't be THAT hard.

Without this patch, mountd failed to recognize that a network/host(s) had changed, if there was no other change to the exports line. As such, the change of network/hosts(s) did not take effect until the mountd daemon was (re)started. This patch fixes the code so that it checks for changes in the network/host(s) list for an exports line.

i think this should work, but it does not. btw, earlier i mentioned "net.inet6.ip6.rfc6204w3". that was a brain fart,= i meant net.inet6.icmp6.nd6_onlink_ns_rfc4861. rfc6204w3 has nothing to do w= ith this. --=20 You are receiving this mail because: You are the assignee for the bug.=
