Unknown system type: Linux 6

[Kucher Dominik]

[ Impact ]

Users that upgrade their kernel to version 6.0 and have ad-hoc changes
to postfix package cannot build it.

[ Test Plan ]

First, we prepare a Kinetic VM with availability to load with a kernel upgrade:

#0. Setting the VM
# lxc init --vm ubuntu-daily:kinetic KLINUX6
# lxc config set KLINUX6 -c security.secureboot=false
# lxc start KLINUX6
# lxc shell KLINUX6
# apt update && apt upgrade -y

#1.Preps for upgrading kernel and getting tools to build postfix

#1.1. Checking we are in LINUX5
# uname -r # this has to return LINUX5 Kernel (5.15.0-60-generic
)
#1.2. Installing mainline
# add-apt-repository ppa:cappelikan/ppa -y
# apt update
# apt install mainline -y
#1.3 Upgrading kernel
# mainline --check
# mainline --install-latest
# shutdown -r now
#1.4 After rebooting, checking kernel version (6.2.8)
# uname -r
#1.5 installing necessary packages for building postfix
# apt install ubuntu-dev-tools libdb5.3-dev -y

#2. BAD CASE
#2.1. Downloading actual postfix's source code in Kinetic
# pull-lp-source postfix kinetic
# cd postfix-3.6.4
#2.2. Generating Makefile (and see expected error)
# /usr/bin/make -f Makefile.in MAKELEVEL= Makefiles

(echo "# Do not edit -- this file documents how Postfix was built for your machine."; /bin/sh makedefs) >makedefs.tmp
ATTENTION:

ATTENTION:
make: *** [Makefile.in:34: Makefiles] Error 1

#3.GOOD CASE
#3.1 Getting the source code (assuming it is in -proposed) with the fix submitted here
# mkdir proposed
# cd proposed
# pull-lp-source postfix kinetic --security
# cd postfix-3.6.4
#3.2 Generating Makefile (process finishes OK)
# /usr/bin/make -f Makefile.in MAKELEVEL= Makefiles

(echo "# Do not edit -- this file documents how Postfix was built for your machine."; /bin/sh makedefs) >makedefs.tmp
set +e; if cmp makedefs.tmp conf/makedefs.out; then rm makedefs.tmp; \
else mv makedefs.tmp conf/makedefs.out; fi >/dev/null 2>/dev/null
set -e; for i in src/util src/global src/dns src/tls src/xsasl src/master src/milter src/postfix src/fsstone src/smtpstone src/sendmail src/error src/pickup src/cleanup src/smtpd src/local src/trivial-rewrite src/qmgr src/oqmgr src/smtp src/bounce src/pipe src/showq src/postalias src/postcat src/postconf src/postdrop src/postkick src/postlock src/postlog src/postmap src/postqueue src/postsuper src/qmqpd src/spawn src/flush src/verify rmail src/virtual src/proxymap src/anvil src/scache src/discard src/tlsmgr src/postmulti src/postscreen src/dnsblog src/tlsproxy src/posttls-finger src/postlogd; do \
 (set -e; echo "[$i]"; cd $i; rm -f Makefile; \
 /usr/bin/make -f Makefile.in Makefile MAKELEVEL=) || exit 1; \
done

cat ../../conf/makedefs.out Makefile.in >Makefile

[ Where problems could occur ]

This fix is part of a stable microrelase. As indicated in the PostfixUpdates MRE exception "Upstream has tight requirements for what goes into stable microreleases, QAs them with regression tests, and has a good history of not breaking anything", which doesn't imply risk-free.

In particular, the fix submitted here adds portability to the postfix package. It doesn't break Ubuntu CI builds and the danger could come from upgrading the kernel itself (that's a risk on the user side, as it is LINUX5 by default -not LINUX6-).

The autopkgtest tests checked the relationships with the versions of the available dependencies and other package-specific issues which is probably what we should focus on to mitigate possible regression scenarios.

[ Other Info ]

It's true that the default kernel in Jammy and Kinetic is not 6.0, but as the upgrade can be done in a kind of supported way through mainline tool,
it's worth adding this fix for these advanced users.

Also, doing this fix because it was part of the latest stable microrelease in the 3.6 band for postfix, and an MRE with it was correctly rejected due to functional regression due to another fix not related to this.

-------------------------------------------------------------

It is not possible to build Postfix on a Linux 6 system!

An upload of postfix to kinetic-proposed has been rejected from the upload queue for the following reason: "Contains a known functional regression".

[Chris Halse Rogers (raof)]

Hello Kucher, or anyone else affected,

Accepted postfix into kinetic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/postfix/3.6.4-1ubuntu2.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-kinetic to verification-done-kinetic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-kinetic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

This bug was fixed in the package postfix - 3.6.4-1ubuntu2.1

---------------
postfix (3.6.4-1ubuntu2.1) kinetic; urgency=medium

  * d/p/1995312-unexpected-eof-fix.patch: Workaround for a breaking
    change in OpenSSL 3: always turn on SSL_OP_IGNORE_UNEXPECTED_EOF,
    to avoid warning messages and missed opportunities for TLS
    session reuse. This is safe because the SMTP protocol implements
    application-level framing, and is therefore not affected
    by TLS truncation attacks. Fix by Viktor Dukhovni (LP: #1995312).
  * d/p/1996524-Linux6-support.patch: Adding LINUX6 support for
    portability (LP: #1996524).

[Robie Basak (racb)]

The verification of the Stable Release Update for postfix has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
