cover Update iptables runtime recommends and add default init scripts and configs

Update iptables runtime recommends and add default init scripts and configs from redhat. That gives users rudimental configures and users only need to update their own iptables rules.

The following changes since commit 7c1a975a1c2fd884aa9f6f4736656d854a6c5edb:

bitbake: toaster: Fix spacing and layout in no image files notification (2014-06-20 14:03:58 +0100)

are available in the git repository at:

As it's for RRECOMMENDS_${PN} your patch will likely work for everyong. Though, you should really only add the ip6* kernel modules if ipv6 is in DISTRO_FEATURES.

(And as a completely unrelated side note, I wonder if it isn't time to start looking at adding an ipv4 DISTRO_FEATURE to make it easier to build IPv6 only devices...)

That's just going to be confusing to anyone who doesn't know that this file was copied directly from RedHat.

Also, is it sensible to ship a static firewall configuration? The one thing we're not is one-size-fits-all.

I just want users could start iptables without any professional work. And these static firewall rules are common for desktop/server.
Or does the empty rule is better? Anyone who wants to use iptables writes his/her own rules. But it is a little difficult for the people who not familiar with iptables.

Any suggestion?

If these rules are common for a desktop/server, do they make sense here? Or should a simplified rule set be your example configuration in that case?

I am thinking put a configure file there without any special rule that allows every input and output. Users could update it with their rules.

Update path of command iptables in init script that we put it in /usr/sbin rather than /sbin. Then update bb file to install init script, configure and rules files.

These new files aren't that big, but could you anyway package at least the rules files into a separate package? Using an RRECOMMENDS would be fine, as I can easily add a BAD_RECOMMENDATION for that package.

It might be that I don't need/want both of iptables and ip6tables installed; or even that I don't want either of those installed by default.

Anders

Of course.

And as I replied in last main, do you think that an empty rule is better? A little concern is for iptables newbies.

It might be that I don't need/want both of iptables and ip6tables installed; or even that I don't want either of those installed by default.

iptables and ip6tables are not split into separated packages, so I put them together. And package iptbales is not installed by default indeed.

Kai

Re: [PATCH 5/5] iptables: update init script and bb file

Update path of command iptables in init script that we put it in /usr/sbin rather than /sbin. Then update bb file to install init script, configure and rules files.

Quoted 8 lines
Quoted 3 lines

These new files aren't that big, but could you anyway package at least the rules files into a separate package? Using an RRECOMMENDS would be fine, as I can easily add a BAD_RECOMMENDATION for that package.

Of course.

And as I replied in last main, do you think that an empty rule is better? A little concern is for iptables newbies.

Well, I'd be at lest a little bit happier to have the ipv6 rules file obey the ipv6 distro feature, see below.

Besides, most users of OE-Core won't have any benefit of a pre-generated iptable rules file. Remember, we're building embedded devices that have everything but a standard setup.

If you want a static firewall configuration supplied by oe-core, can't we package it in a separate package anyway?

No, but at least we're not building IPv6 support into the package if ipv6 is not set in DISTRO_FEATURES. At the very least, the ip6tables rule file should obey that DISTRO_FEATUR also.

I'll update to check DISTRO_FEATURES for ipv6 supports.

iptables: update RRECOMMENDS

iptables: update init script and bb file

Squash these so there's a single commit that adds and integrates a working init script.

Quoted 2 lines

iptables: add default rules
iptables: update rules for ip6tables

Ditto, squash these into a single commit.

Though there is small change for init script, I still want to keep it that make clear which part is our modification.

I prefer to squash

iptables: update RRECOMMENDS
iptables: update init script and bb file

and keep
iptables: add init script and configure file
