[opensuse] rndis and usbnet module symbol problems
Dear All, I am running OpenSuSE 11.3. Since I have an HTC legend Android phone, I want to use the usb tethering from it with my Linux box. In order to do this, I looked for an usb-rndis-lite-kmp package for 11.3. I did not find one (I only found one for 11.2 in the SynCE repository), so I just took the spec file and adapted it for 11.3. The module was built and everything works fine. I can us the tethering from the phone. Unfortunately, there are some modules from the kernel that I can't use any more. For example, once I modprobe the modules from the rpm package (usbnet, cdc_eth and rndis_host), if I modprobe sierra_net, I get: [90376.255544] sierra_net: Unknown symbol usbnet_change_mtu [90376.255847] sierra_net: Unknown symbol usbnet_open [90376.255932] sierra_net: disagrees about version of symbol usbnet_skb_return [90376.255934] sierra_net: Unknown symbol usbnet_skb_return [90376.256121] sierra_net: Unknown symbol usbnet_tx_timeout [90376.256505] sierra_net: Unknown symbol usbnet_start_xmit [90376.256664] sierra_net: disagrees about version of symbol usbnet_get_endpoints [90376.256665] sierra_net: Unknown symbol usbnet_get_endpoints [90376.256857] sierra_net: Unknown symbol usbnet_stop The problem seems to lie in the usbnet module. There are two, one from the kernel and on from my rpm pakcage. Sierra_net, which comes with the kernel, only works with the usbnet from the system. But cdc_eth only works with the one from my package. My question is: why? The "disagrees about version of symbol" error seem to point to the fact that the kernel and the new module were compiled using different compilers. But how is this possible? I always used the compiler from the 11.3 distribution. Has anyone more information on this? How can I build a module that is fully compatible with the kernel I am using (the kernel-desktop)?

Why did you decide you needed to do this? The rndis module is already included in the shipped kernel, the one available from system:SynCE is a patched version. Availability is purposely disabled because some of the (SynCE-specific) patches are a bit hack-y and it's not advised to use it without having a good reason. (I'm the maintainer of system:SynCE btw)

Does it work if you try just using the kernel built-in rndis module? Regards, Tejas -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
@Mark: thanks for pointing me to the 11.3 rpm. However, if you install it and try to modprobe sierra_net, you will get exactly the same problem @Teja: Actually there seem to be no rndis in the standard module that I can modprobe. I see it in the rt (real time) kernel, but not in any other. Thanks for all your help guys!

@Teja:
Wait a sec. You are right. The kernel ships with a rndis_host module.
But Yast was not telling me the same thing and shows the rt kernel as
the only provider of the module. In a few ours I will be home from
work and I will try it out
Thanks

Dear All, thanks to all who helped. All the kernels come in fact with the rndis module, that works perfectly. Thanks again Valerio -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
