I have 3 Dell desktops with a NetXtreme I= I BCM57810 10 Gigabit Ethernet (10Gtek 10Gb PCI-E Network Card) each. One h= as been running FreeBSD 14 (now upgraded to 15) for over a year. One is run= ning Linux. And the third one is running a newly setup FreeBSD 15 instance. The NetXtreme II works fine in the original FreeBSD box (box 1) and always = has. However, it will not work on the new FreeBSD 15 box (box 3). It shows = "bxe0" having "no carrier" (i.e. it thinks no cable is plugged in). But I c= an boot a Linux or OpenIndiana (OpenSolaris) install media on that box, and= the network card will work just fine. In addition, I also experimented wit= h the Linux box (box 2) and booted the FreeBSD installer (14 & 15, actually= ). bxe0 shows "no carrier" on that box, too, even though it has been workin= g fine for a year under Linux. To summarize: Box 1 (FreeBSD 14 =E2=86=92 15): NetXtreme II works just fine under FreeBSD= 14 & 15 Box 2 (Linux): NetXtreme II works under Linux; "no carrier" under FreeBSD 1= 4 & 15 installer Box 3 (FreeBSD 15): NetXtreme II "no carrier" under FreeBSD; works fine wit= h Linux or OpenSolaris installer Box 1: $ ifconfig bxe0 bxe0: flags=3D1008843 metr= ic 0 mtu 1500 options=3D527bb =09ether 98:b7:85:1f:85:45 =09inet 10.0.1.37 netmask 0xffffff00 broadcast 10.0.1.255 =09media: Ethernet autoselect (10Gbase-SR ) =09status: active =09nd6 options=3D29 Box 3: $ ifconfig bxe0 bxe0: flags=3D8802 metric 0 mtu 1500 options=3D527bb =09ether 98:b7:85:20:f8:ed =09media: Ethernet autoselect (none) =09status: no carrier =09nd6 options=3D29 Any thoughts on what might be going on? Any ideas how to troubleshoot this? Of course one would expect the cable or the switch or something like that, = but that doesn't explain why different cables won't make a difference but b= ooting a different OS (without changing the cable) will.

And, > with single UDP stream I would expect all packets to hit the same queue= =2E With a single UDP stream and RSS disabled the DUT gets 2 CPU cores loaded. One at 100%, I understand this is where the interrupts for incoming packets land and it handles receiving, forwarding and sending the packet (with direct ISR dispatch) and another around 15-20%, my best guess that it's handling interrupts for confirmations of packets sent out through the other NIC. With a single UDP stream and RSS enabled the DUT gets only 1 CPU core loaded. I understand that thanks to RSS the outbound queue on mce1 is the same as inbound queue on mce0 and thus the same CPU core handles irq for both queues. > As consequence, with/without RSS should be same (low). It is low for no RSS, but with RSS it's not just low, it's terrible. > Would it be UDP which encapsulates some other traffic, e.g. tunnel that= > can be further classified by the internal headers, like inner headers > of the vxlan, then more that one receive queue could be used. The script stl/udp_1pkt_simple.py (provided with TRex) creates UDP packets from port 1025 to port 12, filled with 0x78, length 10 B. My goal is to test packets per second performance, so I've choosen this test as it creates very short packets. > BTW, mce cards have huge numbers of supported offloads, but all of them= are > host-oriented, they would not help for the forwarding. > Again, since iperf stream would hit single send/receive queue. > Parallel iperfs between same machines scale. It seems that parallel streams forwarded through the machine scale too.

Zeeb CommitDate: 2025-12-08 15:43:51 +0000 LinuxKPI: pci: undo the pci_resource_len() check in lkpi_pci_request_region() Creating non-passthru SR-IOV interfaces on a mlx5en(4) failed. The problem lies in the pci_resource_len() call but not that the BAR le= ngth is tmeporary 0 but in that we call lkpi_pci_get_bar() with a true argum= ent which will create the BAR resource for us and report the approriate len= gth back. However, the later call to bus_alloc_resource_any() will then fa= il given the resource already exists. Restore the previous behaviour and let bus_alloc_resource_any() do the work. Adjust the return values from -ENODEV to -EBUSY to match callers expectations. In linuxkpi_pcim_request_all_regions(), like in linuxkpi_pci_request_regions(), filter out the -EBUSY errors as "not an error" and try the next bar. This also seems to be consistent with the expectations of the callers.

If you disable txcsum on the epair interface, the problem goes away. I just want to understand the root cause of the problem. If I understand your data correctly, then the problem goes away if you set forced_udpcsum to 1. I think the problem should be limited to UDP, because bge devices announce TXCSUM support, but only do this for TCP, whereas the implicit assumption by the rest of the system is that TCP and UDP is supported. Setting forced_udp= csum to 1 enforces support for UDP. The default is forced_udpcsum =3D 0, since Broadcom NICs don't compute the UDP always correctly (I am not sure if this= is currently fixed). We try to reproduce it in my lab, but we need to test it on a system with a Broadcom NIC. Once it is clear, we will work on a solution. As a workaround you can just disable txcsum for the epair interface. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Mon Dec 8 16:33:25 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 4dQ6xG2vT3z6K3hV for ; Mon, 08 Dec 2025 16:33:38 +0000 (UTC) (envelope-from adrian.chadd@gmail.com) Received: from mail-qt1-f173.google.com (mail-qt1-f173.google.com [209.85.160.173]) (using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (2048 bits) client-digest SHA256) (Client CN "smtp.gmail.com", Issuer "WR4" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4dQ6xF69zxz3LNl for ; Mon, 08 Dec 2025 16:33:37 +0000 (UTC) (envelope-from adrian.chadd@gmail.com) Authentication-Results: mx1.freebsd.org; none Received: by mail-qt1-f173.google.com with SMTP id d75a77b69052e-4eddfb8c7f5so46624561cf.1 for ; Mon, 08 Dec 2025 08:33:37 -0800 (PST) X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20230601; t=1765211617; x=1765816417; h=cc:to:subject:message-id:date:from:in-reply-to:references :mime-version:x-gm-gg:x-gm-message-state:from:to:cc:subject:date :message-id:reply-to; bh=1PTPb+iqCX11rayrYer5IhVx8PfqXMOk/bORCRFoFEg=; b=X1l2avJ9nef28ZiiVNjRQe9PXyFFnei9VarZjj1pp4tKw8DxteFPVQ3geHPeZ6k/bp atTxzJ0sLbBKFI8bM2hypca3PpOA2aWFqaYYj3iXJT4tvVVdc+cTCwcJabBhpchUhq6h KV5gWC7UbF0VbdOhcn7aqjD5euOLyUlEUTdTmz0GbjSTdar0iS6tMFifi5r168PxjKyp yL+fPqRCym9dGtQct66HdM88S+VyKrLwqUFgGzlzmHWOi7MQi7wIUxuaJE+TFZV37x81 eEPlU3dYRTz4Y0kWGiraDKjQczdvvvFCBNYFrX2RhLE4eRDhnmPXBGWcuZzGOnXnwbPi KxmA== X-Forwarded-Encrypted: i=1; AJvYcCXQN+31cbwkfk+J/5q34C7ADIzJBs2SmZ3XZQtlfYdeRm5wlswr9b4sD9hWv7R1/vMlJZE=@freebsd.org X-Gm-Message-State: AOJu0YwbIYrB28773j/fAU4sLx/LsYsnB6upjNLV5Kx7KdkMbwmNqrig SZxSxXQxqU8WlBuYYWf7L171NL6qFeuqrzOUTaji5eMlOmYzwbcL4wvCQOyqY9CrEe1kkYozNnc 66+QUXjXw+QLVb6suBZwq+pxmTh2jbHj9/qtc X-Gm-Gg: ASbGnctFXgIbCki1inDLvpMMe0Zd4mPbMh0CdHj+Bb7ALWMwALq+kdHpYkexs0qIhhg 9qVLl0DIL9J7PLJwXEfWUZ1+njRJTAk1XD5Qpi7unOSuwipqZhwbwFYhHbT5Xcx1ya18bh74/kf 69pDocHPU84A6MTCatUIfu5/p8uGroJHPF3macvNWPfdSL7IWU9T9qi+GEe6gE7SEY83hvfUC+B HwwyCOen9qK8hu4bVyoNmoewpT5R2ui7mQi1bSDX+C69ZRKCoIePa/+zLR59zXHKDlpspSqEub6 sQ1BZ1aaWCEo8mQmO4+3HqAGWjWkyw== X-Google-Smtp-Source: AGHT+IHlXi4zwfecTFyeXRKdo0KJmIr8FuJfZzI5fm64buppBaCzwT7P8Yp/xbbilfUKVCCmihzRDxZ4ixkRE76YgSw= X-Received: by 2002:a05:622a:4a18:b0:4ee:2868:4e4a with SMTP id d75a77b69052e-4f03fd4fe1emr132461581cf.14.1765211616771; Mon, 08 Dec 2025 08:33:36 -0800 (PST) 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 References: In-Reply-To: From: Adrian Chadd Date: Mon, 8 Dec 2025 08:33:25 -0800 X-Gm-Features: AQt7F2pJAB0TVsD9lTrKJ5Z2jactmAeKbq6BbBowW9wAqZn6eKOdkPdm2g1_AwU Message-ID: Subject: Re: RSS causing bad forwarding performance?

RSS was never really designed for optimising a single flow by having it consume two CPU cores. It was designed for optimising a /whole lot of flows/ by directing them to a consistent CPU mapping and if used in conjunction with CPU selection for the transmit side, to avoid cross-CPU locking/synchronisation entirely. It doesn't help that the RSS defaults (ie only one netisr, not hybrid mode IIRC, etc) are not the best for lots of flows. So in short, I think you're testing the wrong thing. -adrian From nobody Mon Dec 8 21:44:08 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 4dQFqk75Npz6KRBv for ; Mon, 08 Dec 2025 21:44:18 +0000 (UTC) (envelope-from vegeta@tuxpowered.net) Received: from mail-ej1-x62a.google.com (mail-ej1-x62a.google.com [IPv6:2a00:1450:4864:20::62a]) (using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (2048 bits) client-digest SHA256) (Client CN "smtp.gmail.com", Issuer "WR4" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4dQFqj3fMJz3C8T for ; Mon, 08 Dec 2025 21:44:17 +0000 (UTC) (envelope-from vegeta@tuxpowered.net) Authentication-Results: mx1.freebsd.org; dkim=pass header.d=tuxpowered-net.20230601.gappssmtp.com header.s=20230601 header.b=22fiq2zM; dmarc=none; spf=pass (mx1.freebsd.org: domain of vegeta@tuxpowered.net designates 2a00:1450:4864:20::62a as permitted sender) smtp.mailfrom=vegeta@tuxpowered.net Received: by mail-ej1-x62a.google.com with SMTP id a640c23a62f3a-b73161849e1so78825966b.2 for ; Mon, 08 Dec 2025 13:44:17 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=tuxpowered-net.20230601.gappssmtp.com; s=20230601; t=1765230250; x=1765835050; darn=freebsd.org; h=in-reply-to:autocrypt:references:cc:to:content-language:subject :from:user-agent:mime-version:date:message-id:from:to:cc:subject :date:message-id:reply-to; bh=odlaVl98Q11fBDq/TUOvW4gfRTCF/0kZUJ/1iSRK2z0=; b=22fiq2zMUsJIfW8ZvVI1yWtII8xUZf22dRJnix8z6TkbKAQm7c3f1LCDMnnjD1C+8o 58iVRBD0v6cvucCm8vq9fys10yqImFYdLDKwHLcAFY6lBKUIKp4I0YYLCCT81uVu/zdd Z4UhaRXWJIDmsuKdsx7U1WKAjFC0EFg+7+0U+RPWwSmWlH1tkW05l6DpZ54w4xfmEn6W Q3WKgUFVzddEmkfPYq1Eizu5YiJCB9c4i4BzY+VcC+2twvd8vMKpYrYCcyQ3G3wStR4E 3MrENXeEDSwYh63FxJpQgkw6eM7hPpkPqUg2mSxH9lwkevIdmiZ7rOplfGAhoRWGPCCE 96gw== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20230601; t=1765230250; x=1765835050; h=in-reply-to:autocrypt:references:cc:to:content-language:subject :from:user-agent:mime-version:date:message-id:x-gm-gg :x-gm-message-state:from:to:cc:subject:date:message-id:reply-to; bh=odlaVl98Q11fBDq/TUOvW4gfRTCF/0kZUJ/1iSRK2z0=; b=WF3Sftb/KiLMxp8K4ArPE08W6lqb6geiEr2P4apAB0z7nAgzFPt75wF8xwl4YG0+wj JsCmFucXinhQSUm+DBPyjT+hcUkG6TPrjJhyOotgJFVAo3+LpgJe/U6gDXI9xDuLOVuu ivd+q2yqKYl8z5biwmYWQ1nBcNAiPLxqJERZL60wZ6x4tPeYkZXEJrgUF1xkR4EK6WiM pJYTXRNpTdhRHgtKibDxW1aMsWjl533YmwYun+89rrJZZsLYywdkDi1QGB5wlSia3erx FLUtEbpk2Rna361ulfxkXEod3USXvH5S0hJs8XY/hF8tCTtsOZqK9exLR6anePBOBia/ yq2Q== X-Gm-Message-State: AOJu0YzWIMtpohcgXeH2gA4deHwcqK7+5bAKhz68AyMVveTzNx8AyShU PwvJmys3hxaFx1Bj9Hk6J7k7b3HXdplcgEMtBv3jL1vQ7ADWDdoQupzeFii3+RctSdN7ELX6tZ9 wu/dx X-Gm-Gg: ASbGncueenvRs+HduE+lafJUc9RFjq9r/OBu/rVdyjJA1b1vRtCAehUrN+BKi1a65X5 2x7GXrLNY4Lkzh07ugQfqO8xhbNZB0WrbDFindQPzdfDLEv9DOHTR9Ye32ip/NXNNoeeizDnXtF epQKDr5MHCWZAP8md3rtJr0tNlW+ATrdsqVGlPv3E/5I68O2CEwICbxhuYOmy0VkdlIRh1DeiL0 zH9PO8Q9q9V+tK7uUMV49XSWo0E9l1yeyT8k6VaTYkFZfZfcY6tI8GoqPQlkjSw/ZjJsar7wAa/ 4kIO2HF/JaNMKVEOAKd2i3FY9zyACUcaf3Muinao/CWJr355QMALbY7PIbjadyviI6vaHtignf8 X6s3WCvnK+1zsRMEWUwemIUeisy2oVyNr2bPjpa8m1Ggxwnn3gvt0cXDBFOILKz/v3lrzmxSGLw TBH5BB4KvcqoDppIxdNpmZrXMbvrM86KfpaJhTp4YTrXgPA71N1n/OVOQJrOv12hhJMT8ViKKT7 a8lSajuUdE= X-Google-Smtp-Source: AGHT+IH68qVK2W+X3AjtpcdA0DG/WH1l7AftFspRA7GmHNa6uz1xmYCyFSaULsyBe3H8nm7iKuKFxQ== X-Received: by 2002:a17:907:3f1c:b0:b79:fe3a:6d3 with SMTP id a640c23a62f3a-b7a24777343mr865179566b.37.1765230250068; Mon, 08 Dec 2025 13:44:10 -0800 (PST) Received: from [192.168.178.122] (149.224.164.71.dynamic-pppoe.dt.ipv4.wtnet.de.

When using RSS the mlx5 driver binds queue interrupts to CPUs. To simulate what it would do, but without RSS, I've configured both NICs to have only one queue and then bound the RX NIC to CPU 1 and the TX NIC to CPU 2. I got 3.3Mpps forwarded this way. Then I've bound the TX NIC to CPU 1. The forwarding rate immediately dropped to 0.5Mpps. Both NIC queues on CPU 1: RX IRQ 546/s TX IRQ 546/s dev.mce.1.txstat0tc0.enobuf grows at 3.9M/s Forwarding at 0.5Mp/s mce0 queue 0 on CPU 1, mce1 queue 0 on CPU 2: RX IRQ: 403/s TX IRQ: 85000/s dev.mce.1.txstat0tc0.enobuf does not grow Forwarding at 3.3Mp/s Let's play with the TX NICs sysctls dev.mce.1.conf.tx_coalesce_mode=3D1 dev.mce.1.conf.tx_completion_fact=3D32 dev.mce.1.conf.tx_coalesce_pkts=3D128 dev.mce.1.conf.tx_coalesce_usecs=3D128 TX IRQ: 4300/s dev.mce.1.txstat0tc0.enobuf grows at 1.6M/s Forwarding rate 2.19Mp/s dev.mce.1.conf.tx_queue_size=3D16384 dev.mce.1.conf.tx_coalesce_mode=3D0 dev.mce.1.conf.tx_completion_fact=3D512 dev.mce.1.conf.tx_coalesce_pkts=3D128 dev.mce.1.conf.tx_coalesce_usecs=3D128 TX IRQ: 7700/s dev.mce.1.txstat0tc0.enobuf does not grow Forwarding at 3.39Mp/s Now the TX IRQ can be set back to CPU 1 and forwarding rate is at 3.27Mp/= s. Lesson learned: don't forget about interrupt coalescing on the TX side to= o. --=20 | pozdrawiam / regards | Powered by Debian and FreeBSD | | Kajetan Staszkiewicz | www: http://tuxpowered.net | | | matrix: @vegeta:tuxpowered.net | `----------------------^--------------------------------' --------------OvOSabp5Sn5BRx3B3bD0M0xD-- --------------9hYYcHnQELeKB44TQwnP7RDJ Content-Type: application/pgp-signature;

The checksum problem is specific to bge devices and the root cause is understood. We are still contemplating how to deal with it. Most likely, we will disable txcsum per default for epair. A longer term fix will improve t= he bridge device to handle checksum offloading. I think that the ICMP problem is not related to this. When Timo configured = the IP address not on the bge member of the bridge, but on the bridge itself, it worked. Can you double check? --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Tue Dec 9 19:30:47 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 4dQpqD2M70z6Jg8f for ;

The problem here is that bge interfaces announce TXCSUM support, but only do this for TCP. All other interfaces I know of, support no checksum offloadin= g at all, TCP and UDP, or SCTP, TCP and UDP. Only TCP is what breaks here UDP traffic. Setting forced_udpcsum to 1, adds support for UDP checksum offloading. Unfortunately, the hardware implementa= tion does not handle the case where the computation gives 0 correctly. That is w= hy the default is off. Disabling TXCSUM also avoids being hit by the problem, since then no checksum offloading at all is done. The long term solution will most likely be to add the capability to the bri= dge interface to compute the checksum in software when needed. The short term solution might be just to disable TXCSUM per default for epair... --=20 You are receiving this mail because: You are on the CC list for the bug.= From nobody Wed Dec 10 13:57:17 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 4dRHMy0lqSz6Kbk4 for ;

Hi Peter=C2=A0
im guessing Loopback cable as in a cros= s over cable between two interfaces.. as opposed to a loopback cable plugge= d into the one interface (ie tx - rx=C2=A0 wired together)=C2=A0
=
in principle you want to put the interface you are routing t= o=C2=A0 into a different routing domain...=C2=A0

s= o lets just say you have IP address A on interface A=C2=A0 on the loopback = cable, and IP address B on the interface B on the loopback cable,=C2=A0

put interface B into a different VRF (networking lang= uage)=C2=A0 / Routing domain=C2=A0 Rtable=C2=A0 =C2=A0(openbsd terminology)= ...

run the process you want to send packets insi= de the VRF listening on IP address B ... and set the default gateway routin= g out to Interface A ...=C2=A0=C2=A0


but that is the approach I would use. which just uses routing and=C2=A0 t= he physical cross over cable=C2=A0 between two interfaces...=C2=A0

and all that can be done without VRF leaking in the firewa= ll support=C2=A0 =C2=A0 =C2=A0in PF=C2=A0

Im not s= ure how to do that in FreeBSD... but im sure they support the same function= ality ...=C2=A0


Tom Smyth=C2=A0

I=E2=80=99ve found references that back in the pre-FreeBSD 10 days there us= ed to exist a sysctl:

=C2=A0 net.link.ether.inet.useloopback

that could be set to 0 to disable this internal shortcut and force the pack= ets out onto the cable=E2=80=A6

Any suggestions? :-)

Any suggestions? :-)

You can use a jail + vnet. Ther= e are examples in this pdf:

Zeeb from comment #1) I'm describing the smallest test case I could find: 1. Boot FreeBSD-15.0-RELEASE-amd64-memstick.img from a USB drive 2. Choose "live system" at the first installer menu 3. Log in as root 4. ifconfig wlan0 create wlandev iwm0 5. ifconfig wlan0.50 create vlan 50 vlandev wlan0 inet6 -ifdisabled up 6. Once the machine came back up, I copied the dmesg output I'm working on the assumption that the dmesg output, which appears to captu= re the first boot, the crash, and the subsequent reboot, is not missing anythi= ng important. I can go back and photograph the screen after triggering the cra= sh if that will contain anything more. I did initially find this with an rc.conf equivalent, but there's no IP addresses here, nor is the wifi card connected to any SSIDs yet - although = it does crash in that case as well. I'm not sure why nothing is visible in the dmesg output, unless you're looking for lines logged by the /etc/rc.d/netif. --=20 You are receiving this mail because: You are on the CC list for the bug.= From nobody Thu Dec 11 11:19:14 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 4dRqq837Cpz6KnBr for ;

Any ideas how to troubleshoot this? I have no experience with bxe but it seems it doesn't recognize the SFP+. But given it says: bxe0: Found 10Gb Fiber media. bxe0: IFMEDIA flags : 20 That should be: 13853 sc->media = IFM_1000_SX; and IFM_ETHER The latter ocnfuses me. What does ifconfig -v -m bxe0 show on box3? What happens if you re-plug the SFP+ once the box is up and running? Also, is there a cable attached and the link supposed to be up? Just random ideas; my 5 Pfennig. /bz -- Bjoern A.

I digged into it with if_printf() and printf(). wg_socket_init() runs with port 0 and for each wg interface with the correct listening port. udp_set_kernel_tunneling() registers wg_input(). But when udp_append() is called it never calls the callback function u_tun_= func that should point to wg_input(). It looks like u_tun_func pointer gets lost somewhere. Not left as a wild pointer but reset to NULL. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Fri Dec 12 15:32:24 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 4dSYNn3W4sz6L3sq for ;

I somewhat suspect this may have more to do with pfil address rewriting, some= how, than it does carp.

Another u_tun_func is set for the inpcb associated with wg1.

A bridge with two vnet jails attached to it. One jail running unbound. The second jail running bhyve and an Ubuntu VM with the vm jail's networking se= tup being another bridge of the vnet epair and the tap. The host handles routing for the bridge network for outside connectivity. The VM cannot use the unbound server running in the dns jail for DNS, the U= DP packets have just a partial checksum (according to Wireshark, and it just n= ot working). The VM can use external DNS servers just fine. If one disables tx= csum on the dns jails epair interface it starts working. At least ICMP between the VM and the DNS jail works fine regardless of the txcsum setting. As does DNS from the jail running bhyve. (Out of curiosity I tried if adding the patches for txcsum support for tap devices ( review D51289, review D51291, review D51688) would make a differe= nce (but still on 14-stable) and that also did not change anything.) If it is useful I could provide this test VM image.

In the 15.0-RELEASE variant (which the network configuration is from) I also manually changed that, but given it lacks the txcsum patches there was no change. I'll try to test on this configuration with those txcsum patches to= o. If the jail's bridge turns of txsum then somehow that does not seem to propagate via the epair to the host's bridge however. --=20 You are receiving this mail because: You are on the CC list for the bug.= From nobody Sun Dec 14 03:34:40 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 4dTTMj2gyzz6Kckj for ;

I have successfully verified this TOCTOU issue dynamically, moving beyond t= he initial static analysis. To reproduce the race condition reliably, I set up a QEMU environment with a custom FreeBSD 14.3 kernel. I injected a busy loop (DELAY) in lagg_transmit_ethernet specifically between the protocol check (sc_proto != =3D NONE) and the function pointer call (lagg_proto_start). I then developed a multi-threaded PoC where one thread repeatedly toggles the lagg protocol via SIOCSLAGG while multiple victim threads flood the interface with packets. This setup successfully triggered a Kernel Panic (Fatal trap 12: page fault with instruction pointer 0x0), proving that the protocol can indeed be swit= ched to NONE after the check passes but before usage. Panic Log: Fatal trap 12: page fault while in kernel mode cpuid =3D 1; apic id =3D 01 fault virtual address =3D 0x0 fault code =3D supervisor read instruction, page not present instruction pointer =3D 0x20:0x0 stack pointer =3D 0x28:0xfffffe0068ff2948 frame pointer =3D 0x28:0xfffffe0068ff2970 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, IOPL =3D 0 current process =3D 873 (poc) rdi: fffff8000360a200 rsi: fffff800043c8700 rdx: 0000000000000000 rcx: 000000000000005a r8: fffffe000937c060 r9: fffff800043c8760 rax: 0000000000000000 rbx: fffff80003663000 rbp: fffffe0068ff2970 r10: 00000000000000a0 r11: fffff800046f2740 r12: 000000000000000e r13: 0000000000000008 r14: fffffe0068ff2ac0 r15: fffff80003663000 trap number =3D 12 panic: page fault cpuid =3D 1 time =3D 1765682403 KDB: stack backtrace: #0 0xffffffff80ba8f1d at kdb_backtrace+0x5d #1 0xffffffff80b5aa11 at vpanic+0x161 #2 0xffffffff80b5a8a3 at panic+0x43 #3 0xffffffff8104dbfa at trap_pfault+0x3da #4 0xffffffff81023dd8 at calltrap+0x8 #5 0xffffffff80c85a50 at ether_output+0x6b0 #6 0xffffffff80d21998 at ip_output+0x13a8 #7 0xffffffff80d52c40 at udp_send+0xb60 #8 0xffffffff80c0145c at sosend_dgram+0x31c #9 0xffffffff80c0242f at sousrsend+0x5f #10 0xffffffff80c0aec0 at kern_sendit+0x1c0 #11 0xffffffff80c0b1f2 at sendit+0x1b2 #12 0xffffffff80c0b02d at sys_sendto+0x4d #13 0xffffffff8104e547 at amd64_syscall+0x117 #14 0xffffffff810246eb at fast_syscall_common+0xf8 Uptime: 1m13s Automatic reboot in 15 seconds - press a key on the console to abort --> Press a key on the console to reboot, --> or switch off the system now. I verified that this vulnerable logic also persists in 15.0. While I plan to attempt a reproduction without artificial delays using pure concurrency to further demonstrate the impact, I believe the current result with the widen= ed window definitively proves the bug's existence and mechanism. I suggest prioritizing a fix for this race condition. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sun Dec 14 07:45:50 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 4dTZxV09Fzz6Kwcq for ;

However, by inserting artificial delays to widen the race window, I captured the specific stack trace below.

This confirms a severe lack of synchronization between the data path and the control path, which can lead to various race conditions. I strongly recommend validating any proposed fix by running the attached stress-test scripts for an extended period. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sun Dec 14 19:44:14 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 4dTttQ3tHSz6KkYP for ;

I observed that crashes on the unmodified kernel often appear to stall at ether_output+0x6b0, masking the deeper call chain. The detailed stack trace provided above (showing ether_output_frame, lagg_transmit_ethernet, and lagg_lacp_start) was only obtained after I explicitly added __noinline and __attribute__((optnone)) to the relevant functions to disable these optimizations. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sun Dec 14 19:48:24 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 4dTtzD0sm0z6KkyY for ;

These are likely just examples of many potential failure points caused by this synchronization issue. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sun Dec 14 21:00:41 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 4dTwZf1kkfz6KrV7 for ; Sun, 14 Dec 2025 21:00:42 +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 "R12" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4dTwZd3rlLz3TKW for ; Sun, 14 Dec 2025 21:00:41 +0000 (UTC) (envelope-from bugzilla-noreply@FreeBSD.org) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1765746041; 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; bh=9FRsINhi/OarNz+8H4JCcUqRGbzMd7Y5++IVGBt5qTM=; b=RUsIFUjf7ZYR16pKh68fip7GYnh18zRIiLsEcVGZU2dTTz8VaYWILIfPD/UcdrfXBlpnUB fP4E1obyhCzxmfbxPXOleQHu2Em4sNYRKHoP7B/mwqZkkxlQT1mPJRcxlJ02cGb3z2elzA JE9f8M5+EMR8bX85Ayu2t394VsEu79WlFnm8f0jFh8qDDG2/a32cZJnXWdk5t/8WByQUW2 ONLvvN0FoIDpb3o4UXwn47h+06cv2UVh9EvOpFgf8y67B2M1h+YFCiETXlM1uKgIKxKUyH 7V0LG097K3ahShvEJ9eyXNCe7AJVDZPbXsjO0JoRexbn2tGWKKJcl/izMEf/aw== ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1765746041; 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; bh=9FRsINhi/OarNz+8H4JCcUqRGbzMd7Y5++IVGBt5qTM=; b=FSAhmhy13CFO38YsyA5P+FzbBwaNK7i/EHoP6LYSpPihDVJ7BM+QRXfrjFsap2I8Vtomtz CJYyrkZAbuRYh7MaMkYr2Gjyb4y4DQivWdjw10c5aRAr5ERJ/EeY92YEL5iPa6MaWwXj6H +7C2vDcp3vDksI6lSidR5fN3dIG+UvoK5Tsz4Erh0ee70UMeDLulg4OK52pby8adL1dMDc bhxCk/pPVW05htonuAUvTQkFugkoanibBg4ips/cn9QvuQT0oz6liRL3/72UCJ6q3i1q6q MWrwAgK3s3uFuwktNyxiIc5GMNE0KIux9ojVBb6ciIn8DvgA8scXKiSlLO1VlQ== ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1765746041; a=rsa-sha256; cv=none; b=gSuqL9H7KX/J3kPKyfGukC4HWywkLPmjbJoYDeDF755bh+BHZWkFGQ7trhrpjhlYJ+7HTK y0RCHXiFag+7NaVkew+iiZ77tUm5KzFi+1zochwudg1u6yxbLJZsIZwme7aWHnP8AEufEV PG5681PJsRaHjVOLIeP1b3/fMn1zx4ypvxvL0d+jQBskch3hpInlRiuhBbVbSuJl27O32q vE2vFueBzqvjjgpzwpBSC0HNVuu/CriTJSoxHjl5o8janGwHlDyFRTxQRX+NByArWB3LTn ewP90Xs4YT+g6Z2Y+qFZ/653Xa2c6Qhf1salmRG+BZMvJoqHqD2BPXhRN3EDog== 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 4dTwZd3QBYzqKZ for ; Sun, 14 Dec 2025 21:00:41 +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 5BEL0frF005885 for ; Sun, 14 Dec 2025 21:00:41 GMT (envelope-from bugzilla-noreply@FreeBSD.org) Received: (from bugzilla@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 5BEL0flx005884 for net@FreeBSD.org; Sun, 14 Dec 2025 21:00:41 GMT (envelope-from bugzilla-noreply@FreeBSD.org) Message-Id: <202512142100.5BEL0flx005884@kenobi.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: Problem reports for net@FreeBSD.org that need special attention Date: Sun, 14 Dec 2025 21:00:41 +0000 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: multipart/alternative; boundary="17657460413.d194E41C.2860" Content-Transfer-Encoding: 7bit --17657460413.d194E41C.2860 Date: Sun, 14 Dec 2025 21:00:41 +0000 MIME-Version: 1.0 Content-Type: text/plain; charset="UTF-8" To view an individual PR, use: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=(Bug Id).
