Concrete regression coverage for this fix is ready: a sigint-group autopkgtest
that reproduces the failure (a second Ctrl-C kills the restore vpnc-script
mid-run, leaving route + DNS stale) and passes on fixed code (upstream commit
c0ed1606, setpgid in main.c, released v9.20/v9.21).
Test style matches the upstream suite: needs root + network namespaces, exits
77 (SKIP) when the environment cannot provide them, so restricted autopkgtest
environments degrade gracefully. Validated against master (70d1e79) and the
9.12 tree: FAIL on unfixed code (route/DNS left behind), PASS on fixed.
Debian-side wrapper (debian/tests/sigint-group):
#!/bin/sh
#
# sigint-group - run the upstream sigint-group regression test
# (openconnect teardown survives a second Ctrl-C; Debian bug #1132360,
# upstream commit c0ed1606, released in v9.20/v9.21).
#
# The test needs root and network namespaces; it exits 77 (skip) when
# the environment cannot provide them, like the other netns-based
# upstream tests (dtls-psk, sigterm).
set -e
# This is the installed path to OpenConnect to be tested
export OPENCONNECT=/usr/sbin/openconnect
# Make a copy of the tests directory from the source package, matching
# the style of the upstream-test-suite wrapper
topdir=$AUTOPKGTEST_TMP
testdir=$topdir/tests
mkdir -p $testdir
cp -a tests/* $testdir
cd $testdir
bash sigint-group
Stanza to append to debian/tests/control:
Tests: sigint-group
Depends: @,
ocserv (>= 0.12.1-2),
iputils-ping
Restrictions: needs-root
The test script itself (tests/sigint-group, with the vpnc-script restore
tracking helper) was sent to the openconnect-devel list on 2026-08-24 and is
still sitting in moderation (the list appears largely dormant). Once it is
visible there, the sid side can pick it up alongside the existing test suite,
and trixie p-u can use it to prove the backport.
