The backtrace also indicates the problem is more likely in in6_selectsrc_ad= dr() than in the pfsync code. I don't have any armv7 hardware, and given armv7's status I'm not expecting= to spend any time on this. The problem might be the 'dst_sa.sin6_addr =3D *dst;' line, which might be corrected by doing a memcpy/bcopy instead, but again, I can't test this and it's only going to fix a single instance of this class of problem. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Mon Aug 18 17:19:29 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 4c5KFv0nMdz64CnM for ;

Hi,

Running the pf tests I very occasional (say 1 out of 10 r= uns) see panics freeing an rtentry.
This mostly manifests during bricoler test runs, and usually with the KMS= AN kernel config. I assume that=E2=80=99s because there=E2=80=99s a timin= g factor involved rather than it being an issue that=E2=80=99s directly d= etected by KMSAN/KASAN.

Here=E2=80=99s the panic:

Fr=
eed UMA keg (rtentry) was not empty (2 items).  Lost 1 pages of memory.

Thanks for your help with this frustrating problem. I have set up a 14.3 box with the instructions you provided for enabling TCP Blackbox logging. In my case where I'm running several websites and an Internet based streami= ng radio station I don't want this to be my main server. If/when it reboots it knocks all of my listeners off the station.=20=20 Do you know of a way to stress the Internet connection in an attempt to for= ce a reboot? In my experience this problem is more likely when the connection is busy. As it stands now, this "experimental" server isn't seeing much traff= ic.

Hi,

Running the pf tests I very occasional (say 1 out of 10 r= uns) see panics
freeing an rtentry.
This mostly manifests during bricoler test runs, and usually with the KMS= AN
kernel config. I assume that=E2=80=99s because there=E2=80=99s a timing f= actor involved
rather than it being an issue that=E2=80=99s directly detected by KMSAN/K= ASAN.

I've seen this before, but not in the past few months. I= 'm running with
the default parallelism of 4 most of the time.

I have the distinct impression (but no data to prove it) = that it comes and goes.

We=E2=80=99re panicing because the V_rtzone zone has been= cleaned up (in
vnet_rtzone_destroy()). I explicitly NULL out V_rtzone too, to make this<= br> more obvious.
Note that we failed to completely free all rtentries (Freed UMA keg (rtentry) was no= t empty (2 items). Lost 1 pages of memory.). Presumably at
least on of those two gets freed later, and that=E2=80=99s the panic we s= ee.

rt_free() queues the actual delete as an epoch callback (NET_EPOCH_= CALL(destroy_rtentry_epoch, &rt->rt_epoch_ctx);), and that=E2= =80=99s
what we see here: the zone is removed before we=E2=80=99re done freeing a= ll of the
rtentries.

vnet_rtzone_destroy() is called from rtables_destroy(), b= ut that explicitly
calls NET_EPOCH_DRAIN_CALLBACKS() first, so I=E2=80=99d expect all of the= pending
cleanups to have been done at that point. The comment block above does suggest that there may still be nexthop entries pending deletion even aft= er
the we drain the callbacks. I think I can see how that=E2=80=99d happen f= or
nexthops, but I do not see how it can happen for rtentries.

Is it possible that if_detach_internal()->rt_flushifro= utes() is running
after the rtentry zone is being destroyed? That is, maybe we're
destroying interfaces too late in the jail teardown process?

I don=E2=80=99t think so, I expect all of the if_detach()= calls to be done by the time we hit rtables_destroy() -> vnet_rtzone_= destroy(), because that=E2=80=99s SI_SUB_PROTO_DOMAIN/SI_ORDER_FIRST.
= We should have hit vnet_if_return() (SI_SUB_VNET_DONE/SI_ORDER_ANY) by th= en.

SI_SUB_VNET_DONE is 0xdc00000, SI_SUB_PROTO_DOMAIN is 0x8= 800000 and the vnet_uninit calls are done in descending order, so VNET_DO= NE should be first.

I=E2=80=99m going to kick off a few test runs where I ass= ert that V_rtzone hasn=E2=80=99t been freed yet when we=E2=80=99re in if_= detach_interal() to confirm, because clearly I=E2=80=99m missing some= thing, and it could be this.

But when the panic happens, you have to write a core file. If it just reboots, we don't = have the core to extract the information from. If you don't have a memory constrained server, you might enable BBLog on it= . If you run into any problem, you can issue `sysctl net.inet.tcp.bb.disable_all= =3D1` and BBlog is disabled. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Thu Aug 21 13:03:44 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 4c73RQ0JZ7z64rqK for ;

Doesn't vnet_if_return() just rehome interfaces? I'd expect if_clone_detach() to be responsible for destroying most interfaces (though some are destroyed by the PR_METHOD_REMOVE callback since they hold on to resources which prevent jail teardown.) Various drivers seem to call if_clone_detach() at SI_SUB_PSEUDO, e.g., vnet_gif_uninit(), which will run after SI_SUB_PROTO_DOMAIN during teardown. > SI_SUB_VNET_DONE is 0xdc00000, SI_SUB_PROTO_DOMAIN is 0x8800000 and the > vnet_uninit calls are done in descending order, so VNET_DONE should be > first. > > I’m going to kick off a few test runs where I assert that V_rtzone hasn’t > been freed yet when we’re in if_detach_interal() to confirm, because clearly > I’m missing *something*, and it could be this. > > — > Kristof From nobody Thu Aug 21 19:09:44 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 4c7CYt1sHkz65XpK for ; Thu, 21 Aug 2025 19:09:54 +0000 (UTC) (envelope-from hausen@punkt.de) Received: from FR6P281CU001.outbound.protection.outlook.com (mail-germanywestcentralazlp170100001.outbound.protection.outlook.com [IPv6:2a01:111:f403:c20c::1]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange ECDHE (secp384r1) server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (2048 bits) client-digest SHA256) (Client CN "mail.protection.outlook.com", Issuer "DigiCert Cloud Services CA-1" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4c7CYs2Yb0z3tGw for ; Thu, 21 Aug 2025 19:09:53 +0000 (UTC) (envelope-from hausen@punkt.de) Authentication-Results: mx1.freebsd.org; dkim=none; dmarc=pass (policy=none) header.from=punkt.de; spf=pass (mx1.freebsd.org: domain of hausen@punkt.de designates 2a01:111:f403:c20c::1 as permitted sender) smtp.mailfrom=hausen@punkt.de; arc=reject ("signature check failed: fail, {[1] = sig:microsoft.com:reject}") ARC-Seal: i=1; a=rsa-sha256; s=arcselector10001; d=microsoft.com; cv=none; b=PmOqU8pUiUvidRgVwjg59bYAFunIXMieVDBIl1513HOqUfhY96iEV26wtd/iFrrUPeiKRFi2/QygsKNTdU22A/mUQxMxteLZTeH3KD7hhS6XHiNZ+FoAR1XxhK9swoghWnLtW+9z+3T0mwPQj3PgRXjPozgfBgP2s1122rRlf0DsAPiF1PLV6ik4iJYhAvLRJh4vJ2ykGVFPDD8GTkOkHbOl64XnyiajWMedvvgNBqBS5sxX3g4i73wLjCrVB01xYPWmAdWAElmSJTu0WEh6RHTP+kSlP6UPAPDBE6wnXCk9Mz2NR8sglPWoLGvzStKSt89a4JHKoc6Rc3mvEH+wlA== ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=microsoft.com; s=arcselector10001; h=From:Date:Subject:Message-ID:Content-Type:MIME-Version:X-MS-Exchange-AntiSpam-MessageData-ChunkCount:X-MS-Exchange-AntiSpam-MessageData-0:X-MS-Exchange-AntiSpam-MessageData-1; bh=WtccDcIPSBrOL/MHxcf+s/L0szZUUXf/6R+hMptA1Yo=; b=kEzKf8KB8t3dyMFM/Kgio73WEHnZFOqsPE3ifKs7vbe3BTY3e7W8kU8dpbf142hn3ezBN0yZP1YAWDzq9CDF/qjZ7zGkZbZGcpVNEUJOWNoOOblbYC+iQsjx5cld0elnb6amrOC0+hiT8CqdTeYX37eb/Yno6eSiM7TG5w+TIAF0PNeEu/ZO3Ul/3Jh9piSbjTUPIQJmTv/MqWta3d6Yju7ZwB8wEfmwmFD2WuVa/tEDEHvUp/2w45sYdjCyI5XutyVkazhcTkdDVSGhwi3g5nycbxojlZGOGBAUXXdBO70VmgLBECDWDpxbD0n6geeanByrvkojQJKfq3DaGQUnNA== ARC-Authentication-Results: i=1; mx.microsoft.com 1; spf=pass smtp.mailfrom=punkt.de; dmarc=pass action=none header.from=punkt.de; dkim=pass header.d=punkt.de; arc=none Received: from BEZP281MB3159.DEUP281.PROD.OUTLOOK.COM (2603:10a6:b10:2d::7) by FRYP281MB3185.DEUP281.PROD.OUTLOOK.COM (2603:10a6:d10:40::6) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id 15.20.9052.15; Thu, 21 Aug 2025 19:09:44 +0000 Received: from BEZP281MB3159.DEUP281.PROD.OUTLOOK.COM ([fe80::d3b4:7f52:df34:f8e7]) by BEZP281MB3159.DEUP281.PROD.OUTLOOK.COM ([fe80::d3b4:7f52:df34:f8e7%7]) with mapi id 15.20.9052.014; Thu, 21 Aug 2025 19:09:44 +0000 From: "Patrick M.

Well the rc.d scripts actually run late. =46rom rc.d/netif, ``` # Create IEEE802.11 interface wlan_up $cmdifn # Create cloned interfaces clone_up $cmdifn # Rename interfaces. ifnet_rename $cmdifn # Configure the interface(s). netif_common ifn_start $cmdifn ``` The cloned interfaces are created first, then they, including the = physical interfaces, say em0 and ue0, are configured. So I guess your config of em0 is before vxlan0, and ue0 is after vxlan0. = You may move ue0 before vxlan0 in rc.conf and give it another try.

Yes, you're right ! So vxlan interface is created and brought up prior to the usb ethernet. Hi Patrick, Another approach to overcome this is preloading the driver via = `/boot/loader.conf` since your usb ethernet is always plugged in. I managed to repeat the issue you reported, and can confirm that preload = the usb ethernet driver can workaround it.

I am hoping y'all could help me add more debugging to a FreeBSD 14.= x based router/gateway. The device has two ix(4) NICs for the WAN/LAN. Per= iodically the device stops routing traffic entirely, but the machine is st= ill online and interactive. What is particularly interesting is when I console into the machine I can = still send traffic out from the device over the WAN interface, but anythin= g that relies on the gateway seems to fail. I.e. routing to any host on th= e LAN interface (ix1) no longer works. `service routing restart` does nothing, `service netif restart` also does = nothing. Downing the ix1 interface and bringing it back up does nothing. A reboot however does puts it back into working order. = On one instance the console had a lot of arpresolve "cannot allocate llinf= o" errors, chasing that rabbit led nowhere.

A reboot however does puts it back into working order.=20


On one instance the console had a lot of arpresolve "cannot allocate llin=

Because this freezing behavior is intermittent but _does_ seem to correla=

I'm open to any recommendations that prevent me from setting up a cron ev=

What physical hardware is on that driver?

rring.

Probably.=C2=A0 Do you have TSO and LRO off on at least the extern= al interface?=C2=A0 You might try turning those off on BOTH interfaces.=C2=A0=C2=A0When it goes dead is it Ip4, Ip6 or both?=C2= =A0 =C2=A0I'm on 14.3 but as you can see the kernel is a couple of months old.

I had some funky-chicken stuff going on here with Ip6 for a while with my ISP (Gigabit fiber) when I switched to them from former cable service; the inside interface on my end is on 10Gig SFP+ (Twinax to the switch) where the external is a copper SFP transceiver to the back of the ONT.=C2=A0 I got it sorted; they wer= e being rather persnickety (and odd) in that their end "married" the duid presented to the MAC and my setup runs all out of RAM (nanobsd, thus power safe) and thus by default duid is not invariant across boots.=C2=A0 It only impacted Ip6; it would not ge= t a delegation after the first time it booted unless they reset their end, but Ip4 was unaffected -- apparently they have completely different infrastructure on their end between the stacks when it comes to delegation.=C2=A0 I was able to fix that by making sure th= e duid was in fact invariant but it took a good long while to figure out what was going on, plus they also are a bit bizarre in how they send down route advertisements to my end.=C2=A0 Its been stabl= e now for ~2 months; last reset on that box was some 60 days ago with no network disruptions and I run a fair bit of video streaming out that connection to users on the Internet at-large (the actual source is on the inside network link through a Mellanox card into the switch at 10G.)

My level of success with RealTek 2.5Gb NICs in this service has not been good at all but the ix driver has not caused any trouble.=C2=A0 I saw plenty of issue with arp mappings for the ISP = side of the link just flat-out *disappearing* with the RealTek interfaces from time to time; downing and uping the interface would clear it but obviously that's very bad news and iperf3 into those interfaces would also show ridiculous retry counts thus jitter to stream watchers was off-the-rack.=C2=A0 I know the issue wasn't on the ISP side because an older pcEngines box, while not able to saturate the link, had zero trouble (it has Intel chipset gigabit interfaces in it) as does what I'm using now on the ix interfaces.
