I think I see the problem.

We can reproduce the issue by = adding an artificial delay after the if_attach in ether_ifattach.

In most cases that should not = matter, as at that moment the interface has not been flagged up ( IFF_UP = ) yet.

It works fine and I'd like to commit it soon so it can get proper testing and avoid rotting as a patch. Since I am not src committer I'll need explicit approval to commit to the src tree.

Elsukov from comment #22 & #23) > I still doesn't understand your problem. Me too :) As a result of being stingy with the money I pay upstream (removing services like phone and cable TV), the upstream provider only gives me a /64 prefix = :) In this case, the terminal connected to the downstream interface cannot communicate with the upstream unless the downstream interface belongs to the same bridge as the upstream interface. By using NPTv6, it is possible to make it a layer 3 packet forward. However, since the upstream prefix is already /64, there can only be one /64 prefix available for use downstream. There are two interfaces downstream. It seems that bridging those two interfaces would work, but since it operat= es in a dual stack with IPv4 and dhcpd is also running, it causes issues with = the operation. It was also tried to set a prefix length of /64+x on the interface when receiving a /64 RA from upstream via another patch. This method itself works pleasantly on FreeBSD. However, everything gets ruined because Andr=E2=97=8Bid refuses to operate = with a prefix longer than /64. Wind=E2=97=8Bws also requires that DHCPv6 is running when the prefix is lon= ger than /64. And the keep-state rule was introduced to identify which prefix to choose w= hen translating two or more downstream prefixes to the address of one upstream prefix and then returning it. Since NPTv6 has the same prefix length before and after translation, it see= ms that routing cannot return to the original interface, and this method must = be used. I was considering what to do about the part you pointed out, as the dynamic rules for ICMPv6 require that the addresses on both ends match exactly. As you can see in my patch, normal ICMPv6 packets should have a port value = of 0, so I feel that having a port that is not 0 can be interpreted differentl= y :) In any case, there is no problem with NPTv6 itself. It seems that a person like me is just trying to use it in a strange way :) --=20 You are receiving this mail because: You are on the CC list for the bug.= From nobody Thu May 8 00:37:30 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 4ZtCrq06dTz5vXBr for ;

Thank you for working on this implementation. It looks like complete and ready to ship, but I am only FreeBSD user, so I can't support you much. There is probably concern if your contribution breaks something for the user XY running XXX year old code someone will have to fix it. This fear prevents pushing things further. That's the tradeoff. Please let me note that we are still in pair with NetBSD and DFflyBSD - the cherished implementation from WIDE and KAME projects was left almost untouched. There is no need to modify or rewrite this code; it's decent code, a model implementation, and it will not be a trivial task, but maybe adding enhancements, only tested ones, one by one, is the way to go. It seems that some people have already given up on IPv6 in FreeBSD and do not consider FreeBSD to be a popular OS anymore. Let me cite a 2 and 1/2 years old post from RIPE ipv6-wg mailing list:  "After over 10 (yes, *ten*) years, we have finally addressed security/privacy issues in the generation of IPv6 stable addresses in most popular operating systems. (...) Over time, popular operating systems and packages adopted the proposed algorithm: the Linux kernel, NetworkManager, OpenBSD's slaacd, MacOS, etc. Eventually, virtually every popular OS had adopted the scheme.... except Windows (...)"[1].

Message-ID: <0np2s799-446r-n801-2os5-oqon276851r2@SerrOFQ.bet> X-OpenPGP-Key-Id: 0x14003F198FEFA3E77207EE8D2B58B8F83CCF1842 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; format=flowed; charset=US-ASCII Hi, in 356ab07e2dba0 IFCAP_RXCSUM_IPV6 was introduced along with duplicating all the other bits to not break hardware offload for IPv4. Almost 13 years later I wonder if for any interface (apart from the loopback interface maybe) IFCAP_RXCSUM_IPV6 ever made any difference? A driver would know what RX offload features it can do and one flag should fit all of them. People might say or have said 'but if it is broken for IPv6' we can no longer disable it. Well, yes we can, in the driver as it doesn't make sense for an admin of some hardware having to toggle off a broken feature manually. So I wonder if (temporary, say for 15) we can define IFCAP_RXCSUM_IPV6 to IFCAP_RXCSUM as well, get the bit back as "reserved" during 15 and then be done with it again? I haven't done the full due diligens but a quick grep resulted in a lot of "same code". What am I missing (apart from the painful to do patch)? /bz -- Bjoern A.

I think it could be a simplification. Note that we no longer have a shortage of the cap bits, now that there is at least IFCAP2 and full nv-based cap passing ioctl.

Hi,

Next to hostuuid you could add a jailname in the mix.

That is what ether_gen_addr(9) does to make it easier to prevent collisions while copying jails around or run a jail on a readonly shared base filesystem.

Regards,
Ronald.

I ran several tests in VNET jails to evaluate the combined behavior of D49681 and D50108. Based on the results, I concluded that since the logic is implemented entirely in the kernel, only the host system’s hostid has an effect. This means that cloned or copied jails using interfaces with different names will not interfere with each other. However, if multiple jails are running on the same host and use the same internal interface names, they will be affected by this behavior.

I posted an updated patch, addressing feedback and containing some more improvements.

If testing this new patch, the flag needs to be activated per interface with ifconfig(8) now, or via tunable in loader.conf.

Should generate the same addresses it was generating before, with the only exception of the (relatively improbable) case that the previous patch was generating a reserved IPv6 address, which is now checked for and another one generated in such a case.
