[patch] portknocking module: casting bug

[fender <frozenspot@xxxxxxxxx>]

Hi,
I have received a patch that solves a bug on ixp4xx ARM architectureused on some Linksys. This patch fixes the problem in the iptableslibrary of the port knocking module. The bug causes that port knockingsequence is not property parsed. For example, without this patch youwould get 0,2,0,4,0,6 instead of the port sequence 1,2,3,4,5,6.
Thanks Piotr Gasidło for the patch.
Regards,
