Subject: [PATCH] extensions: libip6t_dst: Fix output for empty options
|
||
|
|
|
||
|
|
If no --dst-opts were given, print_options() would print just a
|
||
|
|
whitespace.
|
||
|
|
|
||
|
|
Fixes: 73866357e4a7a ("iptables: do not print trailing whitespaces")
|
||
|
|
Signed-off-by: Phil Sutter <phil@nwl.cc>
|
||
|
|
(cherry picked from commit 11e06cbb3a87739a3d958ba4c2f08fea7b100a68)
