[Devel] [PATCH 02/14] netfilter: Add {ipt, ip6t}_osf aliases for xt_osf

[Kirill Tkhai]

Porting mainstream commit b8ddd9eac8788b0aa9a9d4e09d76dc9e1667bb2c:

    Orig author: Kirill Tkhai <ktkhai at parallels.com>

    netfilter: Add {ipt,ip6t}_osf aliases for xt_osf

    There are no these aliases, so kernel can not request appropriate
    match table:

    $ iptables -I INPUT -p tcp -m osf --genre Windows --ttl 2 -j DROP
    iptables: No chain/target/match by that name.

    setsockopt() requests ipt_osf module, which is not present. Add
    the aliases.
