Subject: nsresource: fix buffer overrun reported by ASAN
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=41cf6891213dd78c5af3c2b8ff05194c52efa62f;p=thirdparty%2Fsystemd.git

nsresource: fix buffer overrun reported by ASAN

This came up when running systemd-vmspawn with ASAN to fix another bug
and thus I had to fix this overrun here first: The dispatch tables were
missing the terminator, add it.
