# The default syslog implementation should make syslog.service a
# symlink to itself, so that this socket activates the right actual
# syslog service.
#
# Examples:
#
# /etc/systemd/system/syslog.service -> /lib/systemd/system/rsyslog.service
# /etc/systemd/system/syslog.service -> /lib/systemd/system/syslog-ng.service
#
# Best way to achieve that is by adding this to your unit file
# (i.e. to rsyslog.service or syslog-ng.service):
#
# [Install]
# Alias=syslog.service

fuzz-unit-file: simply do not test ListenNetlink= at all msan doesn't understand sscanf with %ms, so it falsely reports unitialized memory. Using sscanf with %ms is quite convenient in socket_address_parse_netlink(), so let's just not run the fuzzer for ListenNetlink= at all for now. If msan is fixed, we can remove this. https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=6884 2018-03-18 15:39:38 +03:00			`#ListenNetlink=`
