Onderwerp: 14.1-R rc.conf/ifconfig netmask issue was really hard to figure out

I had a machine with this line in /etc/rc.conf:

    ifconfig_bla0="192.168.87.11"

I found out the hard way, that this defaults to /8 now.

The main symptom was that DNS was /really/ busted, which makes sense
when none of the DNS servers in the 192/8 "swamp" can be reached.

Since we all know that it is always DNS(SEC), I spent a lot of time
having fun with that, before I noticed the /8 netmask on the interface.

I agree that the class A/B/C netmask assumptions should have died long ago.

But from a foot-shooting point of view, it makes no sense to default
192.168/16 to a /8 netmask.

If we're going to default to /8, at the very least ifconfig should
spitting out a very noisy warning and wait 5 seconds before proceeding,
when the netmask is not explicitly specified.

But I also think we can do better than /8.

One option is to go for "limit the damage in RFC1918" and default
them according to their size: reach:

    10/8
    172.16/12
    192.168/16

That will prevent the DNS weirdness I had to figure out, and probably
still DWIM in most cases.

Another option is to default all three to /24, which in my experience
is how people deploy RFC1918.

A third option is to default any missing netmask to /24 instead of /8,
which would be what I would personally have done in the first place.

What do you thing about defaulting to /32 on a missing netmask?
An interface with 1 IP address without any information about the network. All traffic can go to the gateway.

Ronald.

I completely understand the situation and I can feel your pain, I just wanted to throw in how to reach the default gateway when using a /32 mask. Hence me ending with "in the context of deciding on default behavior when no mask is given this is probably not very helpful". Maybe no news for those following this thread, so sorry if the noise annoyed you. > > We are talking about people who have /etc/rc.conf files which relied > on how default netmasks have worked for nearly three decades, > > Now that we have changed that default, many of them will see a > single line rapidly scroll off their console, and a set of very > bewilding symptoms of DNS not working correctly. We had similar breaking changes with the route command[0] (personally I really would like to support the same syntax for ip/netmasks that is accepted by pf.conf, but that's off-topic). If I remember correctly, there was also a breaking change in the syntax on how to create vlandev's recently. > > The solution is not for them to apply some weird, complex and > unnecessary interface configuration.

Agreed - for RFC1918 addresses at least applying the natural default netmasks (/8, /10, and /16) would feel more logical. The question is if adding all this magic actually makes sense, or if it wouldn't be better to just not accept an IP without netmask anymore (like suggested, make it emit a warning or even make it an error). Ideally, this should have been a warning/deprecation notice a while ago. Going back to previous behavior is probably not an option at this point. One way forward could be to support validating interface settings in rc.conf by using the a "check" or "configtest" subcommand - this is already used by many rc scripts (e.g., `service pf check`, `service nginx configtest`). So there could be `service netif check`, which can be run manually as well as automatically as part of freebsd-update/pkgbase (ideally on a updated config files, but **before** the installation is actually done). It could also run automatically during boot and display an error + sleep 5 in case it finds any issues to warn the admin. Adding such `check` subcommands could actually benefit many rc scripts (e.g., `service mountlate check`). Being able to call check on all rc scripts supporting it with one command could also help admins to identify problems early and therefore give more confidence when reboot testing configuration changes.

I dont think that will work ?

The gateway will not be inside any of the attached networks, so you have no route to it ?

Never attribute to malice what can adequately be explained by incompetence.

Ai. Of course. Typed quicker than I was thinking. :-)

Well. Then it is maybe best to just error out on boot with a misconfigured network. Or revert back to the pre-14.1 behavior because of POLA.

Why have I been bitching for 20 years about how the project just changes "defaults" that effect how a system behavies without any change by the user. In my book these are just plainly WRONG and well, have and continue to bite someone in the ass. No one else seems to complain unless it bites THEM in the ass, well there is ALWAYS and THEM so the project should be far more considerate than they have been, IMHO, about bitting asses, as those asses are connected to the hands that feed this project by growth.

Probably 13.x > @Bjoern I checked again, I'm pretty sure the problem was introduced in https://cgit.freebsd.org/src/commit/?id=4bf44dd73bc0a (this was part of adding netlink into the code). The preparation work by the late Mike Karels was consistent, as one can see in 13.x. So basically the behavior on 13.x is: - ifconfig bla0 10.1.1.1 => 10.1.1.1/8 - ifconfig bla0 192.168.1.1 => 192.168.1.1/24 This is in line with one would expect. On 14.x it's the opposite. The code in 4bf44dd73bc0a68b73f7ee50d52adf5d7cda3eb8 introduced a function to emulate the previous behavior. This function uses IN_CLASSX_NSHIFT as bitmask - therefore 10.1.1.1 uses /24 and 192.168.1.1 uses /8. To fix the code, one has to actually use the bitmask, which is (32 - IN_CLASSX_NSHIFT). So this is simply a bug.

An EN for 14.0 and 14.1 (as suggested in your review) is certainly warranted. As for the path forward, what do folks think about changing the warning into an error in main in the near future (prior to 15.0)? That would provide about four years of releases that emit the warning, hopefully enough time for users to notice and update their configuration.

I couldn't agree more. CPEs, WiFi AP's and most other network(ing) equipment that most users encounter, generally default to a /24 (255.255.255.0).

I opened a review in https://reviews.freebsd.org/D45585 to turn it into an error. I've intentionally made it a minimal change to avoid conflicts on future MFCs; it could be cleaned up and simplified once older branches pass EOL.

I think what Poul-Henning meant is that 31 years ago, in 1993, classless inter-domain routing (CIDR) was introduced by the IETF, and it rendered "class"es of ip addresses obsoletes.

That is an incorrect interpretation of what CIDR does, CIDR did NOT remove the Class A/B/C applied to address space, it simply added functionality (supernetting and subnetting) of the A/B/C space that allows you to do things DIFFERENT than the default /8 /16 and /24 bit prefix length that classfull addresses implied. > -- > Mathieu Arnold -- Rod Grimes rgrimes@freebsd.org From nobody Sat Jun 15 00:00:53 2024 X-Original-To: freebsd-current@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 4W1GWT4nSvz5MJZ3; Sat, 15 Jun 2024 00:00:53 +0000 (UTC) (envelope-from salvadore@freebsd.org) Received: from freefall.freebsd.org (freefall.freebsd.org [IPv6:2610:1c1:1:6074::16:84]) (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 "freefall.freebsd.org", Issuer "R3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4W1GWT41NKz4nVJ; Sat, 15 Jun 2024 00:00:53 +0000 (UTC) (envelope-from salvadore@freebsd.org) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1718409653; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:cc; bh=Zo/nxmY3NMGzs/HocIrbPCQuSo5fsPZ9J+VRhg7pgRI=; b=BmXpTEnXKfoikxGyck0PIOkZxmX0oSBzFLMZQuC59VwG2YT08oBzIm/Mm2T1u2dv4279vg KSR5/RhzqZMkuwNF0AcFDJHiajh6Ix2JxuJ72Rx8kf8fT9S7T+j9wNfSJ1NAY6VzM/2twq 4w9/T29+tmU7JFqN//lgMIwofMMHUuUC60yefUVygOTgmwEjGNq8TNNDvgHfBlaYot7zg/ CRaAiCKrfGunT02/kn2WAGKkI7+4f1RFRLVmvuMwnqIXJ6764BXe8DUnBYrVhDZRsyk2pb ggyTx8+eoBLP7x3Tq4Pt1OP+nKeK9rU/+bn3qpJPHmVr9FeGnS2cgONgh+IM/A== ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1718409653; a=rsa-sha256; cv=none; b=kvkV+3E6Xe+VSv1xTwQjBcaNWbqx9G1362joPwIrgsuW7hqCAnKWmWqZ9FSVBd3XVW8Iun z4+6Al072wIPu95htdwBrB4lwXjPSZwtwoONXJaX4uM6V/zwSRgrohMhzW1VcgNm553EhJ r9eaiPXrhaQ2HEIoM1LjW5xgHEttNW6AY5mZijn1tLeELZeKTBoNbSk95TfXWBhkK+PKA6 9Zslq7X+yiYSyJAy9L+YxhaUABmz23uQxAez5bOiJJugO8TGRKaeXE+KDFY14pEGzH5zeg wqjejiTXu8+IDDSkQbiViBCQqgnYyDI5AY9Cvs19MiIpLXiz9JmazgEYu/ws+Q== 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=1718409653; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:cc; bh=Zo/nxmY3NMGzs/HocIrbPCQuSo5fsPZ9J+VRhg7pgRI=; b=xT+JCujCCxHKan68cALKUVf+aUsO5fhnMjOJKD19yZbS1bEUJ+g95gqXUtNf682gi+sPsU phqRb2+ItdseXPo+xke5LYJIPitaomjHgDYveFEVVg48DQmGFOPsQMxm3xUrHUQPwoq6Wo 1/zcUgOc9evqGYki1EqPihAuUoKTiPE4IkN4KM+lKO2PUx1o++BN9WNsjHjVT6IB9hmDtm 2y1xsrjl7pZt4GlUBnC1r1Y8nQGBYApeNHvOJpRH+ukpbryHRdmE8vvL6HWgBS/WJoFKo7 dpUrqadgBVFpyZj+s91ko77E6YLKYOJS8nY2snHzq4SOB2M9oxcrQjq/cSpvTA== Received: by freefall.freebsd.org (Postfix, from userid 1472) id 51428133AA; Sat, 15 Jun 2024 00:00:53 +0000 (UTC) To: freebsd-status-calls@FreeBSD.org Subject: [2 WEEKS LEFT REMINDER] Call for 2024Q2 status reports Cc: freebsd-current@FreeBSD.org,freebsd-hackers@FreeBSD.org,devsummit@FreeBSD.org,info@bsdcan.org,soc-students@FreeBSD.org,soc-mentors@FreeBSD.org Message-Id: <20240615000053.51428133AA@freefall.freebsd.org> Date: Sat, 15 Jun 2024 00:00:53 +0000 (UTC) From: Lorenzo Salvadore List-Id: Discussions about the use of FreeBSD-current List-Archive: https://lists.freebsd.org/archives/freebsd-current List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-current@FreeBSD.org Dear FreeBSD Community, The deadline for the next FreeBSD Status Report update is June, 30th 2024 for work done since the last round of quarterly reports: April 2024 - June 2024. I would like to remind you that reports are published on a quarterly basis and are usually collected during the last month of each quarter, You are also welcome to submit them even earlier if you want, and the earlier you submit them, the more time we have for reviewing. Status report submissions do not need to be very long. They may be about anything happening in the FreeBSD project and community, and they provide a great way to inform FreeBSD users and developers about work that is underway or has been completed. Report submissions are not limited to committers; anyone doing anything interesting and FreeBSD related can -- and should -- write one! The following methods are available to submit your reports: * submit a review on Phabricator and add the group "status" to the reviewers list. You should put your reports in the directory doc/website/content/en/status/report-2024-04-2024-06/ (create it if it is missing); * submit a pull request at . You should put your reports in the directory doc/website/content/en/status/report-2024-04-2024-06/ (create it if it is missing); * send an email to status-submissions@FreeBSD.org including your report. An AsciiDoc template is available at . We look forward to seeing your 2024Q2 reports!

if anyone wants ZFS images for BASIC-CI I can add them easily enough). And another change will be happening some time in the next few months: * The non-filesystem-labelled images, which are identical to the UFS images and exist for backwards compatibility with scripts which were written before we added support for non-UFS images, will cease to be published on 15.x (but remain on older branches).
