Summary: Misparsed command line containing --line
Product: iptables
Version: 1.4.x
Platform: arm
OS/Version: other
Status: NEW
Severity: major
Priority: P4
Component: iptables
AssignedTo: netfilter-buglog at lists.netfilter.org

Note: the error message for --line[-numbers] contains <hyphen><zero>. There is
neither a short option zero nor a short option O.
[ 0 ] app_42 at android:/# iptables -v --line -A OUTPUT
iptables v1.4.10: Illegal option `-0' with this command
Try `iptables -h' or 'iptables --help' for more information.
[ 2 ] app_42 at android:/# iptables -v0 -A OUTPUT
iptables v1.4.10: option `-v0' requires an argument
Try `iptables -h' or 'iptables --help' for more information.
[ 2 ] app_42 at android:/# iptables -v -0 -A OUTPUT
iptables v1.4.10: option `-0' requires an argument
Try `iptables -h' or 'iptables --help' for more information.
[ 2 ] app_42 at android:/# iptables -v -0 foo -A OUTPUT
iptables v1.4.10: option `-0' requires an argument
Try `iptables -h' or 'iptables --help' for more information.
[ 2 ] app_42 at android:/# iptables -v -0 foo bar -A OUTPUT
iptables v1.4.10: option `-0' requires an argument
Try `iptables -h' or 'iptables --help' for more information.
[ 2 ] app_42 at android:/# iptables -v -0 1 2 -A OUTPUT
iptables v1.4.10: option `-0' requires an argument
Try `iptables -h' or 'iptables --help' for more information.

Short option O produces the same errors:
[ 2 ] app_42 at android:/# iptables -v -O 1 2 -A OUTPUT
iptables v1.4.10: option `-O' requires an argument
Try `iptables -h' or 'iptables --help' for more information.
[ 2 ] app_42 at android:/#
As it turns out, this is a situation in which iptables processes the entire
command line before attempting to access the filter table, so -A does not
short-circuit the error for ordinary users.
