[Bug 1804508] Re: dropbear-initramfs init-bottom script uses wrong ps options, can't kill descendants
This seems to be fixed since at least focal. dropbear (2018.76-3) unstable; urgency=medium * debian/initramfs/bottom-dropbear: + Read and parse /proc/*/stat instead of ps(1)'s output, as ps(1) options differ between Debian and Ubunt's busybox. Thanks to 'eviljoel' for the patch.

I patched this issue with the following fragment
if PID="$(cat /run/dropbear.pid)" 2>/dev/null &&
[ "$(readlink -f "/proc/$PID/exe")" = /sbin/dropbear ]; then
log_begin_msg "Stopping dropbear"
# Patch issue #1804508
# Kill all children and the parent dropbear
kill -TERM $(ps l | awk '$4~/^'$PID'$/ {print $3}') $PID
log_end_msg
fi

[Bug 1804508] Re: dropbear-initramfs init-bottom script uses wrong ps options, can't kill descendants
I'm using the attached patch on my system without issue, but it only kills direct children instead of everything in the process group. (busybox's kill doesn't support PGID at all from what I can see) It might be possible to solve this with a change to busybox-initramfs for additional ps options, or include /bin/busybox instead of /usr/lib /initramfs-tools/bin/busybox. ** Patch added: "dropbear.patch" https://bugs.launchpad.net/ubuntu/+source/dropbear/+bug/1804508/+attachment/5215081/+files/dropbear.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804508 Title: dropbear-initramfs init-bottom script uses wrong ps options, can't kill descendants To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dropbear/+bug/1804508/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
