Good evening!
I am trying to install an external WIFI antenna on my tablet (BQ Maxwell 2 Plus, rooted, CM10.1). The model of the antenna is TP - Link 722n.
I have downloaded the drivers from backports project and, after compiling them, I have 8 .ko modules:
- ath.ko
- ath9k.ko
- ath9k_common.ko
- ath9k_htc.ko
- ath9k_hw.ko
- cfg80211.ko
- compat.ko
- mac80211.ko
When I try to insmod the cfg80211.ko module, an error occurs. The dmesg output is:
Code:
cfg80211: exports duplicate symbol __ieee80211_get_channel (owned by kernel)
Anyone knows a way to solve the problem?
Thanks!!!
Finally I made it!
The problem was that the kernel included both cfg80211 and mac80211 drivers, so what I needed to do was to compile it without them.
After that, I flashed it in the device and insmod the drivers.

Need help with compiling modules for Dell Streak kernel.
Because i could not find cifs.ko module for mounting network shares for Dell Streak stock Froyo 318, i decided to make it on my own.
I did not have any clue how can it be done, but with lot of googling and reading forum posts on xda and modaco, i got vague idea how i can do it.
There was lots of trial-and-error attempts until i learned how to use all comands and tools, and here is final list of things id did to make it:
Already had VMWare workstation with Ubuntu 10.10 instalation, i got Android Froyo source tree from net, replaced kernel with Dell Streak 3.09 kernel (from opensource.dell.com) which is also Froyo, i think, and is closest to my kernel version (318).
Got toolchains from codesourcery.com
Extracted my phone config from /proc/config.gz, renamed to .config, uncommented and changed option for CONFIG_CIFS=m. Did same for tun.ko module which i did not need, but just for comparison. Placed .config file in kernel root.
Did comand:
Code:
make ARCH=arm CROSS_COMPILE=/path-to-toolchains/bin/arm-none-eabi- modules
after confirming some options (irellevant to this), and some compiling in terminal, all went ok without errors and did produce modules in fs/cifs and drivers/net
i also did some debugging to reduce filesize, bud also had tried module without debugging with same result (see below)
transferred modules to my phone in /system/lib/modules and tried to load them via insmod.
loaded tun.ko without problem (i dunno whteher is working because i have no means to try it and have no need for it). i compiled it just to see whether it will be loaded in phone kernel. it DID load without error messages.
when tried to load cifs.ko via insmod cifs.ko, got this error message:
Code:
insmod: init_module 'cifs.ko' failed (no such file or directory)
dmesg provided following errors:
Code:
cifs: Unknown symbol slow_work_register_user
cifs: Unknown symbol slow_work_enqueue
found in similar thread for Galaky Tab that i need to compile slow_work module and load it before because of that dependancies, Found another thread with instructions for compiling slow-work, followed them:
copied all slow-work files in cifs, Remove the calls to round_jiffies in fs/cifs/slow-work.c: round_jiffies(jiffies + SLOW_WORK_CULL_TIMEOUT)); changed to
jiffies + SLOW_WORK_CULL_TIMEOUT); AND round_jiffies(jiffies + SLOW_WORK_OOM_TIMEOUT)); TO jiffies + SLOW_WORK_OOM_TIMEOUT);
edited fs/cifs/Makefile and added slow-work.o to the obj-$(CONFIG_CIFS) += cifs.o line: obj-$(CONFIG_CIFS) += cifs.o slow-work.o.
Ran make command from above, got both modules (cifs.ko and slow-work.ko) in fs/cifs directory without errors.
Copied them to phone, done insmod and got error for slow-work:
Code:
insmod: init_module 'slow-work.ko' failed (no such file or directory)
dmesg provided following message:
Code:
slow_work: module licese "unspecified" taints kernel
slow_work: Unknown symbol mutex_lock_nested
Now i'm clueless (like i haven't been all the time :-D).
All modules compiled without errors, tun.ko will load, cifs.ko apparently need slow-work to run, slow-work compiled, but can't load.
So, if somebody can help, or point me where is possible error, i will be very grateful.
UPDATE:
Found references for missing slow_work modules in cifsfs.c and misc.c, deleted them and ran make.
produced cifs.ko without error.
LOADED cifs in phone without error!!!! With lsmod it shows that module is loaded!
BUT, does not work! Cannot mount anything. When tried with cifsmanager or manually via terminal get error message "No such device" which points that there is no valid cifs.ko module in kernel.
So, module is produced and loaded in phone without errors, BUT DOES NOT WORK. It looks like Streak Froyo need slow-work module after all...
I'm desperate, please if somebody did compiling cifs.ko for Streak, or use cifs mounting with found module, share your thoughts and experiences.
Thanks everybody.
CIFS and Slow worked - compiled
I was able to successfully compile both the slow work module and the CIFS module for the most recent 4G EVO. Took me a couple of days, but I think I could walk you through the specifics fairly easily. Let me know if you want the details.
of course I do!
please write your way.

dmandic, did you ever get this working? I went through similar pains doing this for the xperia arc, and did manage to get it working. I have some thoughts about your situation if you want to discuss further.
please, any help is appreciated.
i'm open to any kind of suggestions.
write your thoughts here.

Hmm. I originally stumbled upon this thread because I was searching for others who compiled a cifs.ko against a kernel with version "2.6.32.9-perf" (from the android about phone menu), hoping to avoid going through figuring out how to do this. I saw that others with the Dell Streak also had this kernel, and then I found your thread.
Anyway, I was thinking that maybe the kernel you got from the dell website had a slightly different version than your phone (because your phone is 3.18 vs 3.09), and that's why you're getting runtime symbol errors. I thought maybe there's a chance you needed exactly 2.6.32.9-perf and I could offer you mine. However, I downloaded the dell 3.09 kernel source and found that it's also 2.6.32.9-perf... so I guess that idea's out the window. (By the way, is this what your phone shows?)
Well just for kicks, I actually compiled slow-work and cifs from the dell kernel and loaded it on my xperia arc phone and they worked (was able to use CIFSManager).
It's a long shot but just in case there's something about the way you're compiling them, I attached them here - give it a try. [Edit: Duh, I forgot I need your .config file. Email it to me and I'll re-post these]
I tried out the Xperia files from the thread [DEV]TUN, CIFS modules files on my Streak 5. It did not go well, these are my messages from dmesg.
Code:
<4>[ 341.187030] tun: Unknown symbol dynamic_debug_enabled
<4>[ 341.190600] tun: Unknown symbol dynamic_debug_enabled2
<4>[ 341.219513] slow_work: module license 'unspecified' taints kernel.
<4>[ 341.220411] slow_work: Unknown symbol mutex_lock
<4>[ 341.638099] cifs: Unknown symbol mem_section
<4>[ 341.638397] cifs: Unknown symbol mutex_lock
<4>[ 341.641609] cifs: Unknown symbol slow_work_register_user
<4>[ 341.642835] cifs: Unknown symbol slow_work_enqueue
Looks like the kernel is differently compiled and or still some modules missing.
I noticed that in another thread Samba/CIFS for Motorola defy froyo nls_utf8.ko also has been required, however I do not have the 2.6.32.9-perf version of this to try it out.
How has the progression been for you guys?
I'm trying to compile the rtl8187 kernel module for my archos 101 g9, I've pulled the archos-gpl-gen9-kernel-ics git repository and I've used the android-ndk r8 to compile the modules. Everything looks perfectly fine (the vermagic is matching the other modules "3.0.8+ SMP preempt mod_unload ARMv7" no issues there) except when I try to insmod the eeprom_93cx6.ko (This module needs to be loaded before the rtl8187.ko) I get told in dmesg "eeprom_93cx6: unknown relocation: 27"
After googling around it hasn't really helped me any.
So hopefully you guys can help me out. Any ideas of whats causing the above error?

Hi !
You can try to update :
sudo apt-get install build-essential
sudo apt-get install libssl-dev
...and now recompile the module ....and also you need to take a look at Module.symvers - look into it an see if export symbols !

Thanks for replying.
I'm using the latest build-utils and libssl for my os and inside my Module.symver the modules does appear.
Code:
0x00000000 eeprom_93cx6_read drivers/misc/eeprom/eeprom_93cx6 (unknown)
0x00000000 eeprom_93cx6_multiread drivers/misc/eeprom/eeprom_93cx6 (unknown)

Ok !
Seem to be good ! If you want I can try to compile for you ...but I need your source module ...I will take a look tomorrow if you upload it !
Digging deeper into google I actually found a solution, adding -fno-pic to the compiler flags stops the error.

EDIT:
Yesssssss, Originally inserting the realtek dongle was causing a backtrace to appear in the dmesg but unloading the built-in modules (compat, wl12xx*, mac80211, and then cfg80211) and then loading my compiled modules (cfg80211, lib80211, mac80211, eeprom_93cx6, and then rtl8187) has resulted in success
So finally got my tablet where I want it, arch linux chroot with aircrack-ng / kismet running on it nicely with my alfa dongle. Thanks for trying to help me solve my issue at least surdu_petru
Compiled Modules tested and working on surdu_petru's 4.0.7 rooted rom.

Im trying to compile the rtl8187 driver for my s3 - could you point me in the right directions to try and compile it. My s3 is rooted running a custom kernel. Thanks.

I was trying to download the rtl8187 for my device that you posted and the link is bad. Any chance I can get it from you? Im trying to get an 8187.ko to work on my MK808 TV Stick and the rtl8187.ko that I have is giving me an "exec format error" when I insmod.
Hello,
I've recently bought a MELE A1000 [link], which currently has ICS and Linux kernel version 3.0.8.
But I've come across a problem; my Xbox 360 wired usb joystick isn't working with the MELE.
Research tells me that the module isn't compiled/included in the kernel [link]
This gives me two options, each with it's problems:
1- Re-compile the kernel, including the Xpad module:
I'd have to get the kernel source (either this "generic" kernel, or this Allwinner-specific kernel) then include it in the boot image, which is specific for the MELEA1000 link (check the first comment with the Chinese link to the official image)
Problems with this option
a) I don't know if the generic kernel will work with my device (Are there differences other than included modules?)
b) I can't compile the specific Allwinner kernel for some reason
c) Will the specific boot image work with a custom kernel? I think so.
2- Compile and include the module with insmod
I'd have to get the source of the ffmemless module [Source] and the xpad module [Source], compile them and do insmod to get them working.
Problems with this option
a) I can't seem to compile the modules in the correct version for my kernel (kernel 3.0.8+ #24 PREEMPT, armv71)
b) the precompiled modules I found were for 2.6*
Easiest scenario: compile modules + insmod.
Ideal scenario: get custom kernel, working + mod the rom (this is not within this thread's scope)
Could you give me any links, ideas or keywords to help me continue?
PS: I'm a programmer and I have previously modded/compiled kernels (from Debian's official repositories though)
Thanks
With information I've been reading I got up to this point:
Download the ARM kernel
git clone git://github.com/amery/linux-allwinner.git
Install the necessary libraries / binaries
apt-get install gcc-4.4-arm-linux-gnueabi build-essential u-boot-tools (if u-boot-tools not found, try uboot-mkimage)
Configure
make ARCH=arm sun4i_defconfig
make ARCH=arm xconfig
Check the following modules:
Input device support -> Support for memoryless force-feedback device
Input device support -> Joystick / gamepad
Input device support -> Joystick / gamepad -> X-box gamepad
Compile the modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j3 INSTALL_MOD_PATH=output modules
Then move the xpad.ko module to the MELE and run insmod xpad.ko, but I'm stuck with xpad: disagrees about version of symbol module_layout
I'm guessing this is a compile issue.
I've started a blog in which I'll try to document everything I do in the most detailed way I can.
Cheers
I think easier will be to get already compiled modules for A10 3.0.8+ from some firmware. I got cp210x.ko from "Aurora CM9 Nightly By Feiyu 0803.zip", successfully insmod-ed it into my device, and later added that insmod command to autorun with script manager app. I checked xpad module - it is in this firmware.
First sorry for my bad english, I want to port or make a module for the Oukitel k10000 PRO with kernel 3.18.35+ from the usb wifi TP-LINK WDN3200 (The usb driver is rt2800usb.ko), I get the .ko file and insmod the file and I get:
Code:
insmod 'rt2800usb.ko' failed (Function not implemented)
I want to use in a chrooted linux and I dont know how to cross compile the driver.
Can someone help me? or guide me to do that? Thanks.
Hello, i'm trying to add cifs.ko kernel's module to my rooted (with Magisk) Redmi Note 9 Pro (Joyeuse Global).
On my Ubuntu computer, i've cloned smb3-cifs-linux-stable-backports (linux 4.14, the same kernel version as my phone run) and compiled the cifs.ko module using
Code:
make -C . M=fs/cifs ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
The kernel module compiled successfully, then I've created a Magisk module which load into /vendor/lib/modules the compiled cifs.ko, but I get
Code:
insmod: failed to load cifs.ko: Required key not available
, but my compiled kernel module isn't signed and i've checked a factory kernel module : isn't signed too.
I don't know what i've done wrong, if someone can tells me how to do and how.
Thanks
could you resolve this? I want to add cifs in the same kernel (v4.14.180). do you have the cifs.ko file? thank you!
