[Lamobo-R1] [5.20] swconfig & problem with last 5.20 Armbian update

Rui Ribeiro · September 16, 2016

Hi,

Did today a kernel update...upon reboot, has no connectivity. I have lost swconfig; copied the one that comes with the sdcard/img download, it booting the switch by default, but does not allow to do much more...the reset and set operations are giving an error.

What could I do?

zador.blood.stained · September 16, 2016

Please install this swconfig (and remove the one you copied manually to be sure that you are using the new one): http://apt.armbian.com/pool/utils/s/swconfig/swconfig_15.04-1~armbian5.20%2B1_armhf.deb

After that, please post exact output/error messages that you have.

Rui Ribeiro · September 16, 2016

Thanks Zador.b.s, it has got exactly the same behaviour.

root@ruir:/etc/network# swconfig dev eth0 set reset 1

failed

root@ruir:/etc/network# swconfig dev eth0 set enable_vlan 1

root@ruir:/etc/network# swconfig dev eth0 vlan 101 set ports '3 8t'

root@ruir:/etc/network# swconfig dev eth0 set apply 1

failed

root@ruir:/etc/network# uname -r

4.7.3-sunxi

root@ruir:/etc/network# swconfig list

Found: switch0 - eth0

zador.blood.stained · September 16, 2016

And output of

swconfig dev eth0 help

please

@zador.blood.stain

thanks, I thought I had a problem 2 days ago when I compiled the kernel (I copy/paste the swconfig binary from older debs)

Probably default compiler settings for packaging are wrong, I'll have to tweak these and make some versions for testing.

Rui Ribeiro · September 16, 2016

wildcat_paris · September 16, 2016

@Rui

check if you still have the old binary in /usr/local/bin/

whereis swconfig

test it then overwrite the /sbin/swconfig

so Zador has spare time to fix this problem

Rui Ribeiro · September 16, 2016

@goldfich_paris Even I had checked earlier with find, I checked again after your post. I do not have it. Thanks.

root@ruir:/sbin# whereis swconfig

swconfig: /sbin/swconfig

wildcat_paris · September 16, 2016

ok, I uploaded my working binary, not a clean way but should be working

I looked at

objdump -D -M intel /sbin/swconfig

but it is ASM and I don't read ASM fluently

Rui Ribeiro · September 16, 2016

@goldfish, your binary restored my switch

wildcat_paris · September 16, 2016

@Rui

Cool, so we have a workaround solution for others Lamobo-R1 Armbian users

Rui Ribeiro · September 16, 2016

@zador, last binary still problematic.

zador.blood.stained · September 16, 2016

@Rui Ribeiro

Thanks, I hope this will be sorted out in next release, meanwhile we need to find and test working sources for swconfig and use precompiled one before that.

Rui Ribeiro · September 16, 2016

@Rui

Yep, specially problematic for me as the R1 is my home router...

No problem, I am using the one from golfish.

wildcat_paris · September 16, 2016

@Mikhail

if it can help

the "old" swconfig has (with readelf)

0x00000001 (NEEDED) Shared library: [libdl.so.2]
0x00000001 (NEEDED) Shared library: [libc.so.6]

the new one

test1

0x00000001 (NEEDED)                     Shared library: [libnl-3.so.200]
0x00000001 (NEEDED)                     Shared library: [libnl-genl-3.so.200]
0x00000001 (NEEDED)                     Shared library: [libc.so.6]
0x00000001 (NEEDED)                     Shared library: [ld-linux-armhf.so.3]

test2

0x00000001 (NEEDED)                     Shared library: [libnl-3.so.200]
0x00000001 (NEEDED)                     Shared library: [libnl-genl-3.so.200]
0x00000001 (NEEDED)                     Shared library: [libc.so.6]

so as I am using Ubuntu 14.04 and the binary "looks like" for Ubuntu 15.04

Maybe there is a library issue.

edit: I have the libnl-3

looking more closely I have libnl 3.2.21 it seems I would need libnl (network library) 3.2.24

maybe it is not related.

The pthread library seems out of place here.

@goldfish the difference in size is because the new is stripped

Even then, after stripping

zador.blood.stained · September 17, 2016

@goldfish_paris

@Rui Ribeiro

Difference in size and used libraries suggests that the old binary was statically linked with libnl* and stuff, the newer one wasn't.

wildcat_paris · September 17, 2016

@Mikhail

while this one (generating swconfig*15.04*.deb) seems to be broken

https://github.com/jekader/swconfig

this one (also doing debian packaging "debuild -uc -us" and closer to openwrt) works ok

https://github.com/xypron/swconfig

edit:

before using debuild -uc -us

./autogen.sh has to be launched (if not there is no binary)

the Bananian switch.h has the same xypron/swconfig switch.h

but looking at the diff of the 2 files (openwrt-mirror vs. Bananian), I am surprised the compilation can even work, there are many more enum-ed attributes.

I am thinking of a conspiracy of Bananian over Lamobo-R1 users

zador.blood.stained · September 18, 2016

PS: Nice people developers, please test your code that working on 100% before to release new versions

Except that

This is not "our code", this is wrong configuration for someone else's code
This is not "core functionality" and can easily be fixed by replacing a single file
We don't have all the boards that are listed on download page, some boards are just assumed to work since they are similar to others
Even if we wanted to extensively test all the images, it would probably take several weeks and a box of microSD cards to do it

tkaiser · September 18, 2016

This is not "core functionality"

This is not even 'known to work' functionality: http://linux-sunxi.org/Lamobo_R1#Security_Implications (trying to use a dumb switch for routing/security purposes is just wrong)
