I'd be interested to see the 3 thread race that actually makes this code fail. The more you think on this race, the more you would think that the code that does it is not correct. By definition, if your *m->m_ext.ext_cnt is 1, then you OWN this mbuf, and nobody else should see it. So how does two other find it? Given that bug report is quite old, I'd prefer not to change any code unless submitter comes back and gives more information. btw, thanks for bring it up, Zhenlei. I totally missed it, and didn't know about its existence. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sat Mar 15 02:53:11 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 4ZF5QJ6SSqz5rCHX for ; Sat, 15 Mar 2025 02:53:12 +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 "R10" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4ZF5QJ5h06z3y15 for ; Sat, 15 Mar 2025 02:53:12 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1742007192; 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=BzUBBBVQ+O026JMXOTtm/Nba8aAwM3zBE5Xn/ttFU3Y=; b=A35IhIvNveVgb/u58XRbELUEBadxsYp9sQzO2P1vwcUmDc+q+bqNuwM62DLg9dg6FiteUJ VLDIf1U6KGxdHJiSAyxLDhMOebZvSjmR2TmFsA9agrSCbTl4BEV65ufPC3Z1M9x0IB8EDn aL1V2FTHqLq+34mB5qFBJbQhdpLr4FtCQjSAp9FaGM7SNeL8Xj+PvbIwCRx9qimUsJ0omD 4xI4JdfChLqKI093gL0XvBifjx9gIyM8tAvWw89iTzLYI5wPLa3iWbl4p6HWnjCBlYJe6t lnwCgv2QJIeauw9weSekP7oCLkMWMwieaAcu3/3l8ZUgKWGkzgqXZ8KmQD820Q== ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1742007192; a=rsa-sha256; cv=none; b=njyKnFfdsSeX5zedObQFw6cUuWuj2D31AB4DaY8eh49mi/ygh2C+gPokr3s4mNGR+M1Jey am+ty91nSRU7u6LlQKl+VfheXoa6Spa9IUml2O9vmky4OArJxEYL/9GbVusVphCuMVtiPW CsxCwVdZWZnjYYoSqPRMkZpJ0/a4t+xeRvA9t2YcbCtUYtaRLUKmj1mZW6pZxCQ5h4VlQE yFG0LobPajj1IBkJHBCJrZKdIkqsQP6A5c/IOdEF1MKFOWXmvw1VGoL+CccWbPVLi8is7D qooyWSzpaXemdZbXByieoUbxoUewMxbZKL6m8B4OvhXT8n43mwmZmbZ6xooVzQ== ARC-Authentication-Results: i=1; mx1.freebsd.org; none ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1742007192; 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=BzUBBBVQ+O026JMXOTtm/Nba8aAwM3zBE5Xn/ttFU3Y=; b=tBa/fF4NwkYnJrc9lkKQ1SeEogHS2GHV435b0bi16PXnv49IVB0k0MZYbaIO96R0AMRznq R0/64aY8Rovzam1J6o/tzRZ38TFv+Hf97XgRqoX4Z5KAvTLUxk3mtzKZ4JFiiMqd6cx34n ypg+ptUOFgK4JKTRZ6ueFiTUPuUzROHFsloVP/gmP818sp943HNt+JtJ2uN0QSKzn0lpsa h/RG6bdk23c/5aGJd2sCLQJHH4355jAkJrPcDjNTucBOkHjcihmfkwFRk5xFLuCU6TzNcP /zfC+86YhGBSVZhLV3fwDwLGSxSZJx1rJG60NxyTl4jA1jxgF/qsIAla62LwHA== 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 4ZF5QJ5F3lz1BZM for ; Sat, 15 Mar 2025 02:53:12 +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 52F2rCGU046714 for ; Sat, 15 Mar 2025 02:53:12 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from bugzilla@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 52F2rCGk046713 for net@FreeBSD.org; Sat, 15 Mar 2025 02:53:12 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 284857] wg(4): IPv4 packet with IPv6 nexthop not forwarded Date: Sat, 15 Mar 2025 02:53:11 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 15.0-CURRENT 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: kevans@freebsd.org X-Bugzilla-Flags: mfc-stable14?

If we have a valid header that matches a known peer, then we have no reason to decline the packet. Convert it to an assertion that it matches the destination as viewed by the stack below it, instead. `dst` may be the gateway instead of the destination in the case of a nexthop, so the `af` assignment must be switched to use the destination in all cases. Add a test case that approximates a setup like in the PR and demonstrates the issue.

In RFC 5735 we can read: 0.0.0.0/8 - Addresses in this block refer to source hosts on "this" netw= ork. Address 0.0.0.0/32 may be used as a source address for this host on this network; other addresses within 0.0.0.0/8 may be used to refer to specified hosts on this network ([RFC1122], Section 3.2.1.3). Why do you think that address 0.0.0.0 is the wrong one? You can still use t= he loopback address as the source for ping here:=20 # ping 2.2.2.2 -S 1.1.1.1 --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sat Mar 15 08:03:18 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 4ZFDJ61d1Nz5qLwq for ;

But there is a scenario of multiple owners, some dropping their reference a= nd some just getting it. For example, let's start with refcnt of 2 and three threads: T1, T2, T3. T1 and T2 are getting a new reference while T3 is dropping its reference. There is also another owner, Tx, that just keeps its reference. 1. T1 reads refcnt, sees 2; 2. T3 decrements refcnt to 1 3. T2 reads refctnt see 1; 4. T2 proceeds to non-atomic *refcnt +=3D 1 and reads refcnt as 1 again; 5. T1 proceeds to atomic_add_int and increments refcnt to 2; 6. T2 sets refcnt to 2 as well (based on step 4); In the end, we have 3 owners (T1, T2, Tx) but the refcnt is 2. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sat Mar 15 15:40:10 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 4ZFQRH57S6z5qyvT for ;

As Cheng pointed out, this can help keep some state fresh ( idle window), or help elicit a retransmission from the other side, when one of the final pac= kets from a non-RACK stack was discarded and these empty ACKs serve as dupacks.= =20 This is not only in PRR but other phases as well, when you look closely into the behavior of the FreeBSD stack. Do you have evidence of this behavior being detrimental to anything? --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sun Mar 16 15:06:30 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 4ZG1dz20C8z5qcHj for ;

I don't know what kind of code people can write to manipulate mbuf, this is just a theoretical example. Larger point is why have the special case, does it provide a lot of win for performance? I know that atomic operations are expensive. A branch is not free, however, too.
