OpenWRT MetaROUTER with 12.09 and Linux 3.3 [PATCH and tgz]

RouterOS Virtualization
1

I have purchased a Routerboard 750GL and I’m currently waiting for several PPC-based Routerboards to be shipped.

I’m highly interested in the Metarouter functionality described here:

http://wiki.mikrotik.com/wiki/Manual:Metarouter#OpenWRT_as_virtual_machine

I’ve created a patch against the latest OpenWRT stable release (attitude_adjustment) which compiles MIPS and PPC cleanly as of the latest attitude_adjustment/12.09 rev (r37811). I’ve updated the kernel patches for PPC and MIPS to support Linux kernel version 3.3.8.

When I boot the MIPS image (RouterOS 6.2 on 750GL) Metarouter reports the machine as “running” and this is the kernel output from the console:

Where it hangs…

I’m betting PPC might “just work” because I had to do far fewer shady things to port it to Linux 3.3.8. Unfortunately I can’t test it because I don’t have the hardware!

Any help, support, or suggestions would be greatly appreciated. I have the patch and binary images available here:

http://www.kriskinc.com/mikrotik-metarouter

Thanks!

unfortunately there is no output on the terminal with PPC image.

3

Thank you for trying my image on PPC hardware; that’s not a good sign. I’m still working on MIPS and PPC will have to wait until my hardware gets here.

Thanks again!

Hi Kristian,

Did you get progress for the Mips ?
I’m very interested in a up-to-date openwrt metarouter port.

Thanks
Pierre

5

This might not have to do with anything that Kristian did wrong with his patch, but might be because of the bug in PPC RouterOS that prevents any custom kernel from booting under RouterOS 6 MetaROUTER (ticket 2013100466000193; see http://forum.mikrotik.com/t/bug-custom-metarouter-kernels-no-longer-work-on-ppc-w-ros6/70244/1). Did you try booting Kristian’s PPC image under 5.26?

– Nathan

6

yes, the output is the same. That is - no output.

7

I’ve just recreated this exact issue, tested a RB951G originally on 5.25 and now on 6.7.

The MikroTik provided image works fine, a manually built image from OpenWRT svn (as per MikroTik) and patch 1.2 also works fine, but attitude adjustment with the 1.3 patch has absolutely no output at all.

I’ve been looking at the various patches with a view to porting to a much more recent OpenWRT kernel and I don’t think it’s quite as simple as just porting the 1.2 patch as there seem to be quite a few significant changes to the mips tree, and even the way the various mips options are structured.

If you look at the 3.3.5 patch that Mikrotik appear to use then you can see quite a few different ways of doing things for the “vm” board type. If you look at the sections within CONFIG_MAPPED_KERNEL you’ll see lots of new stuff that wasn’t in the 1.2 patch, presumably to deal with changes in the mips implementation.

I think the answer will be a combination of bits of the 1.2 patch and the 3.3.5 patch.

I’m going to see if I can build a vanilla 3.3.5 kernel with the 3.3.5 patch and just hack it into an OpenWRT image, that way I’ll know whether it will start to boot or not … I know it won’t subsequently work, but it will make it clear whether it’s worth trying to port the 3.3.5 bits to 3.3.8 or later.

Lee.

Ok, I’ve made some progress … I now have a 3.3.5 kernel which appears to boot. The console isn’t working properly, so I don’t get any of the boot messages, however I do get the following:

[Ctrl-A is the prefix key]

init started: BusyBox v1.16.1 (2010-04-13 10:25:42 EEST)
/etc/init.d/rcS: line 17: can't open '/dev/null'

At this point my guess is that the startup messages are hidden as this is the same behaviour with the standard non-openWRT metarouters, or it could just be that I’m not using the virtual console properly somehow in my .config … I will investigate further.

I don’t think it will be too much of a stretch to port this to 3.3.8, but I’d like to get to the bottom of the console problem first.

Lee.

Update: I’ve fixed the console by doing a clean build, so it was a problem caused by adding .config items as I was testing.

Bear in mind this is just a bare kernel build, with minimal config just to get it working, it’s not a proper OpenWRT kernel yet. But it’s a pleasing start!

Lee.

AFAIK, patch 1.2 has to be updated with stuff from 3.3.5 patch.

11



MikroTik’s own kernels have always been configured/patched to not print out boot messages. They do this by redefining the DEFAULT_CONSOLE_LOGLEVEL preprocessor constant in printk.c from 7 to 1. (They only do this in their full kernel patch sets, not the ones that contain only the MetaROUTER subset.) Traditionally, I have simply thrown out their entire patch to printk.c since as far as I can tell, the rest of their modifications to it have to do with providing a hook for RouterOS to intercept printk messages (perhaps for the purpose of being able to collect them and then, say, stash them inside of SUPOUT files?), which we obviously have no use for in OpenWRT.

So your experience is interesting. Perhaps DEFAULT_CONSOLE_LOGLEVEL can be overridden inside of .config, in which case I’m not sure why MikroTik bothers patching the source code file directly.

(To onlookers of this thread, it should be pointed out that the issues with booting MetaROUTER kernels on PowerPC RouterOS are unrelated, and this console ‘fix’ isn’t a solution for that problem. We’re only talking about the MIPS kernel port here.)

MikroTik’s own kernels have always been configured/patched to not print out boot messages. They do this by redefining the DEFAULT_CONSOLE_LOGLEVEL preprocessor constant in printk.c from 7 to 1.

This is really interesting because I left this patch in yet I seem to be having full messages on the console.

I genuinely believe my earlier problem was because I was manually changing .config to add the options one at a time to get the build working, and I wasn’t doing a clean rebuild each time, and some of the last adds were around the HVC and VIRTIO.

That said, it doesn’t explain why I’m seeing log messages! I’ll look at this more closely later.

I got a vanilla 3.3.8 kernel to build and run ok, I’m now fighting with OpenWRT and the sheer scale of their patches that impact the MikroTik kernel stuff.

Lee.

13

Ok … not sure what was happening with the console, it’s behaving as expected now.

I have a build of OpenWRT now working with the 3.3.8 kernel, unfortunately there are still issues to be resolved. The failsafe mode works ok, but once it starts trying to load modules you get this:

[ 0.000000] ------------[ cut here ]------------

I can’t say I’m surprised because the whole module.c stuff for relocating modules looks completely different. There’s an openwrt patch (305-mips_module_reloc.patch) that looks like it covers all the stuff that the Mikrotik main patch had, so I took most of the Mikrotik stuff out … perhaps it wasn’t the right approach.

[EDIT] I’ve fixed this issue, it was the is_phys_addr() function. Now it just hangs after loading a few modules. More digging to do…

[EDIT] This is now ok as well (school boy error) … now I have a “kernel bug” when you have an interface configured. Getting there!

Lee.

14

I’ve cut a load of stuff out of the patch to try to get back to basics, but I’m still struggling with a bridge related problem:

It’s all fine up to the point an interface is configured, then I see the kernel bug as above … experimenting with failsafe it’s pretty clear that this is a direct result of adding a ‘bridge’ rather than eth0. brctl add causes it immediately.

I’ve spent far too many hours on this today … will resume tomorrow.

Regards,

Lee.

15

OK … now it seems to be working … I’ve deleted lots of the MikroTik patch, which is a bit of a shame, but now I have a fully functional (at least as far as I have tested) mips Attitude Adjutment build.

I’ll try to get back to a controlled state and then post a patch tomorrow.

Regards,

Lee.

16

Here is an initial patch … a few comments:

  1. This is against Attitude Adjustment (12.09) r39154.
  2. I have only looked at mips, the ppc code is in there but I haven’t tested a build or created the target stuff for it
    (I don’t have a ppc system, so can’t test this anyway)
  3. This is based on the MikroTik 3_3_5 patch (but applied to 3_3_8.)

I have removed the tile stuff and a few other bits from the 3_3_5 patch, but there is still a lot of stuff in here that isn’t needed for metarouter so it’s currently much bigger than it needs to be, but it will take a while to unpick as there are lots of dependencies.

My plan at this point is to simplify as much as possible and then see if I can get it ported to trunk.

I’m keen to hear if anyone else gets this to work!

Regards,

Lee.

OK, final post for a while (hopefully) …

I effectively started again only putting in the 3_3_5 patch stuff that I though was necessary, so all of the extra stuff is now removed, this is a much simpler patch, and much closer in spirit to the original 1.2 patch from Mikrotik.

I have produced two patches, one for Attitude Adjustment 12.09 (r39154) and one for the current trunk (r39218) which is kernel 3.10.24.

Some cavates:

  1. This is only for mips, I have only tested on the RB951G so far.
  2. I have only done very basic testing … checking it boots and recognises an interface.
  3. I am not a kernel or mips expert so I may have broken stuff, especially on the trunk one.

Enjoy, and let me know how it goes.

Regards,

Lee.

There are still problems with this … at least on trunk…

[EDIT] This does appear to be only a problem on trunk, it seems ok on 12.09.

I will continue to investigate…

I try to work with the patch for 1209 instead of the official metarouter-1.2 but when I run make menuconfig I cant find Mikrotik MetaROUTER MIPS at Target System.

Do i make something wrong?

Hi,

You need to download the 12.09 release from OpenWRT using either git or svn…

git clone git://git.openwrt.org/12.09/openwrt.git

Then you need to apply the patch… (replace patch_file with the full or relative path to the patch)…

cd openwrt
patch -p1 < patch_file

Then you should be able to “make menuconfig” and you’ll see “Mikrotik MetaROUTER MIPS” under the target systems item.

Regards,

Lee.
