Subject: [PATCH] nft: Fix command name in ip6tables error message
|
|
|
7cc531 |
|
|
|
7cc531 |
Upon errors, ip6tables-nft would prefix its error messages with
|
|
|
7cc531 |
'iptables:' instead of 'ip6tables:'. Turns out the command name was
|
|
|
7cc531 |
hard-coded, use 'progname' variable instead.
|
|
|
7cc531 |
While being at it, merge the two mostly identical fprintf() calls into
|
|
|
7cc531 |
one.
