Subject: [PATCH] xtables-translate: don't fail if help was requested
|
||
|
|
|
||
|
|
If the user called `iptables-translate -h` then we have CMD_NONE and we should gracefully handle
|
||
|
|
this case in do_command_xlate().
|
||
|
|
|
||
|
|
Before this patch, you would see:
|
||
|
|
|
||
|
|
user@debian:~$ sudo iptables-translate -h
|
||
|
|
[..]
|
||
|
|
nft Unsupported command?
|
||
|
|
user@debian:~$ echo $?
|
||
|
|
1
|
||
|
|
|
||
|
|
After this patch:
|
||
|
|
|
||
|
|
user@debian:~$ sudo iptables-translate -h
|
||
|
|
[..]
|
||
|
|
user@debian:~$ echo $?
|
||
|
|
0
|
||
|
|
|
||
|
|
Fixes: d4409d449c10fa ("nft: Don't exit early after printing help texts")
