|
|
|
|
the change causes non-ipv6 addresses to not be printed at all in case
|
|
a nfproto was given.
|
|
|
|
Also add a test case to catch this.
|
|
|
|
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1117
|
|
Fixes: 5ab0e10fc6e2c22363a ("src: support for RFC2732 IPv6 address format with brackets")
