TOR fails to run on stable OrangePi Zero build

Hi!

Just installed Orange Pi Zero Armbian (xenial stable legacy kernel - I still want some internal wifi )

But, tor package from default repository is failing.

Error:

Jul 18 22:36:52 localhost systemd[7985]: tor@default.service: Failed at step NO_NEW_PRIVILEGES spawning /usr/bin/tor: Invalid argument

Jul 18 22:36:52 localhost systemd[1]: tor@default.service: Main process exited, code=exited, status=227/NO_NEW_PRIVILEGES

This applies to default tor version and tor version from repository of torproject.org (https://www.torproject.org/docs/debian.html.en)

System info:

orangepizero:~$ uname -a

Linux orangepizero 3.4.113-sun8i #18 SMP PREEMPT Thu Jun 15 02:16:06 CEST 2017 armv7l armv7l armv7l GNU/Linux

orangepizero:~$ cat /etc/armbian-release

# PLEASE DO NOT EDIT THIS FILE

BOARD=orangepizero

BOARD_NAME="Orange Pi Zero"

VERSION=5.31

LINUXFAMILY=sun8i

BRANCH=default

ARCH=arm

IMAGE_TYPE=stable

Exactly the same issue is here: http://tor-bugs.torproject.narkive.com/C3javj0U/17713-tor-debian-8-2-latest-tor-package-tor-0-2-7-5-1-d80-jessie-1-amd64-deb-fails-on-start-with-no-

We have 0.2.7.6 i guess, but symptoms are the same.

Tried "haveged-like" fix with NoNewPrivileges=yes - it just fails immediately with same error. Removing this options lets tor process to run for 5-7 seconds.

Thanks in advance for handling this if possible.

This means that "NoNewPrivileges" option is not correctly applied to the TOR service. What file did you add it to? Did you reload the systemd configuration?

Edit:

You need to add something like

[Service]
NoNewPrivileges=no

to a new file - /etc/systemd/system/tor@.service.d/10-no-new-privileges.conf

this should apply this setting to all TOR instances. "sudo systemctl daemon-reload" is required to reload the configuration after changing.

Upstream Debian Jessie relies on kernel 3.16, Ubuntu Xenial - on kernel 4.4. "NoNewPrivileges" option tries to use kernel features that are not present in kernel 3.4, so it has to be disabled first.
