I am trying to compile and insert the CFG80211.ko module
I have built an Ubuntu VM and installed the correct codesourcery cross compiler.
I have been able to build several modules which successfully insert. (ntfs, lib80211, all three lib80211_crypt modules, all three wusb modules, uwb, veth etc etc)
however the cfg80211.ko module always fails with invalid argument.
dmesg reports :-
Code:
[140146.246732] cfg80211: disagrees about version of symbol wireless_send_event
[140146.246751] cfg80211: Unknown symbol wireless_send_event (err -22)
cfg80211 depends on rfkill which is, as far as I cant tell, precompiled into the phone kernel.
the relevant section of the config file is as follows:-

I have tried converting RFKILL to a module, in order to enable CONFIG_RFKILL_INPUT to yes but the compile completely fails when this is set.
I have added WIRELESS_COMPAT details in the Kconfig file but this did not help and I am now lost as to how to troubleshoot this?
Anyone have any idea on what might be missing?
If you're able to compile the modules, you should be able to compile the kernel - do the modules insmod against the compiled kernel?

Yes all the other modules I mentioned all insert fine the ones that I have compiled that dont insert have dependancies that all stem back to the cfg80211.ko that is giving me the messages in the first post.
from the documentation cfg80211 is dependant on RFKILL which is precompiled into the kernel.

Ahhh rereading your post, I see what you mean, I haven't installed the built kernel (though I did do the full build) on the phone, not entirely sure how to package it and I haven't tried to look because I really dont want to install a full kernel on the phone.
In any case I have used the default samsung config to build from fro the correct kernel.

Are you installing the kernel and modules, or just the modules? If you are just installing the modules, are you using an IDENTICAL version of gcc, with nothing changed between N<=>M<=>Y except for your rt2x00 module in the .config?
useful information would be:
Your kernel version string from the phone: uname -a
A diff of the base .config and the new .config: diff -ubw orig.config new.config
A diff of the phone's working .config and your .config.
You can generally get the .config your running kernel was compiled with from /proc/config.gz on the device. You would then need to gunzip that and compare it to your .config with the diff command above.

Unfortunately /proc/config.gz support is not configured in the samsung kernel by default therefore the file is not present. uname gives 2.6.35.7-I9100XXKH3-CL479037
And I have tried the recommended codesourcery cross compiler and one other variant of this and the results are the same.
it's a stock rom with an insecure kernel (basically a repack of the stock kernel) to allow rooting from what I can gather.
I have tried many configuration of build from the default .config and just building the top dependancy module from the default config
In this case the top of the tree is CFG80211
(rt2x00usb depends on rt2x00lib, depends upon mac80211, mac8211 depends upon cfg80211 and cfg80211 depends upon rfkill. There are also some dependencies on kernel crypto libraries which I am unclear about but should be in the kernel build)
I have found it makes no difference at all if I build lots of modules at once or just the very bare CFG80211.ko with as few options as possible. The failures are the same trying to insert cfg80211.ko. as it is whether I use busybox insmod, standard insmod or insmod from within a chroot. (in the searches I read modules can behave differently with busybox)
the only changes I made from the samsung default config is switching some debugging options off as per this thread http://forum.xda-developers.com/showthread.php?t=1123643
other than that it is a stock samsung default config for a 2.6.25.7 kernel build, as distributed in the samsung source code.
I haven't had the nerve to install the fully built kernel because the phone is a key tool for me reflashing a kernel is kind of a last resort
The attached rar file includes the default config (c1_rev02_premium_defconfig) the config used (.config) the output of diff -uwb between the two (differences.txt) and the two modules built ntfs.ko and cfg80211.ko.
file reveal ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), not stripped on both modules. (done chroot)
I use ntfs.ko as a control since it's a small module and in this build it inserts just fine. cfg80211.ko fails with the same message and dmesg info mentioned in the first post.
As I previously mentioned I did try modifying the RFKILL sections to be built as a module but when this is attempt the kernel build fails completely with the error:-
Code:
ERROR: "s3c_gpio_slp_cfgpin" [arch/arm/mach-s5pv310/c1-rfkill.ko] undefined!

Thanks for looking at this for me
Do you have a link to your kernel tree? I'd suspect that CFG80211_WEXT being enabled makes some changes in the WEXT functions that get compiled in kernel. With CONFIG_WEXT_* being =Y, your enableing CFG80211_WEXT probably made things not agree. Also, I believe the rt2x00 driver is a mac80211 one, so you'll likely need that too.
In summary, you'll very likely have to use your own kernel to get this going. At least loading the ntfs.ko answers that it's not a toolchain/source tree issue.

This error is due to another missing dependency (and the lack of proper dependency definitions in KCONFIG). You need to do:
egrep "s3c_gpio_slp_" -rsn
to find where those functions are defined, and find out why they're not being compiled. It's quite likely something like enabling rfkill for your arch/tree pulled in that c1-rfkill file (is your board a c1?) which is either not for your actual device, or dependent on something else being enabled. This is wholly based on previous experience with HTC kernel trees, where files from other Boards seemed to tag along.
I have no samsung hardware (although the GSII is on the list of what I'm considering ;-) )

I am aware I'll need other modules but they all come back to dependancy on CFG80211 so I am concentrating my efforts around that.
The link to the kernel tree is
git://opensource.samsung.com/p_497
but I have also used :-
https://github.com/GalaxySII/samsung-kernel-galaxysii
with the exact same results.
The config_wext elements are listed under the bluetooth elements, but I am firstly concerned that disabling these elements with adversely effect the standard wifi comms. which would not be acceptable even if I could package and install a fully kernel build. (which I can probably do enough research, on this site, to work out eventually, although I admit to some trepidation about this).

Ok, per:
https://github.com/GalaxySII/samsun...gt-i9100-gingerbread/net/wireless/wext-core.c
Lines: 434, 548, and 613, 653
Your kernel will have to be replaced to have cfg80211, mac80211, and rt2x00 working. There is no way around this, as that code is compiled into the kernel, and cfg80211 and mac80211 depend on those function doing more than your kernel does. There's no way around it. That's only analyzing the wext-core... there may be other differences.

Hey xda people,
I have been looking for custom Galaxy S 3 i9300 Wifi Drivers to enable monitor mode. At first i figured out that the device has a "Murata M2322007 WiFi Module" on board.
Source: stuff-review .com/2012-06/samsung-galaxy-s-iii-receives-the-teardown-treatment/
"Murata supplies its M2322007 WiFi module, which features Broadcom's (BRCM) BCM4330"
Source: seekingalpha .com/article/647181-the-galaxy-s-iii-supply-chain-winners
It workes with Broadcom's that means aircrack has a support for right?
Aircrack Driver List: aircrack-ng .org/doku.php?id=compatibility_drivers
brcm80211 - brcmfmac (SDIO) driver: BCM4330: wireless.kernel .org/en/users/Drivers/brcm80211
Has anyone have a clue that i go to the right direction? Or isnt it possible at the moment because code has to rewriten before it works?
I did little more research and found this about the Galaxy S II: ns3.spinics .net/lists/linux-wireless/msg85390.html
I found this and downlaod the firmware. But is this the right one? and how can i install it on my android?
"Alternatively, when not available the Android version can be used as well:
git clone https :// android.googlesource .com/platform/hardware/broadcom/wlan

Lupo,
Could you please upload that firmware files somewhere? This f**ing git is pain in ass ((
Thanks in advance!!
BRs,

According to the i9300_defconfig, the i9300 has a BCM4334. This is also confirmed by looking at the device behind the wlan0 interface:
Code:
$ grep . -H /sys/class/net/wlan0/device/* 2>/dev/null
/sys/class/net/wlan0/device/class:0x00
/sys/class/net/wlan0/device/device:0x4334

/sys/class/net/wlan0/device/uevent:MODALIAS=sdio:c00v02D0d4334
/sys/class/net/wlan0/device/vendor:0x02d0
Monitoring mode appears to be supported if WLP2P and WL11N (depends on WLP2P) are disabled. On i9300, both configuration options are enabled, which prevents adding monitor interfaces:
Code:
# iw dev wlan0 interface add mon0 type monitor
command failed: Operation not supported on transport endpoint (-95)
See function wl_cfg80211_add_monitor_if in kernel/samsung/smdk4412/drivers/net/wireless/bcmdhd/wl_cfg80211.c. After disabling that ifdef, and the ifdef near interface_modes (in function wl_setup_wiphy), I could add a monitor, but this interface was unusable.
Another attempt, this time with the following patch:

Unfortunately, the network module does not load at all (getting I/O timeouts in dmesg).
I think I'll go for a USB adapter + USB OTG cable instead of messing with this driver.
Aside, according to the mainline Linux sources (checked 3.12), the device is supported by the brcmfmac module which does not support monitor modes yet: http://wireless.kernel.org/en/users/Drivers/brcm80211#To_be_done_for_fullmac_driver
(I know this is an old post but for those interested int he answer, here's one).
You've to differentiate between the wifi driver (in the linux kernel) and the firmware (that is uploaded to and runs on the bcm4334 chipset).
WiFi driver cracking is (quite) easily doable.
But there's normally no need to patch the wifi driver: If you're running a standard bcmdhd DRIVER, cracking tools should be run after a LD_PRELOAD of the fake driver library to make them understand the interface is in monitor mode, without changing the driver.
Now, for the firmware part...
bcmon team said:
We are currently working on GS3&4 support (which have a different broadcom chipset), we will release it “when it’s done”.
Click to expand...

And that was mid-2013. Bcmon team has not shown any sign of life since (maybe they've been caught by Qualcomm! ).
So that means, if you want bcmon to work on the Galaxy S3, you've to crack the firmware binary code yourself.
And good luck because cracking steps are superficially documented and human-readable patching source code is non-existent.
i found a way to get it working
flash i9100 kernel modifed and use bcmon
Hey friends, I am interested in this post, I have a s3 and a mini, I have seen that they have the wifi chip BCM4334 and it is exactly what they are talking about in this post for trying to put it in monitor mode, I still have not tried it but I would like , I wonder if you know what to do in detail, I have read every thing in the post, but in the end it seems that all have died, but if anyone is here, he has my time and interest in doing everything, I can create an apk that can be compatible with this chip, I do anything if you explain how and I will do it until I get it, if I have to desigrar any thing I will do but if they explain how. THANK YOU!.
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.

Yes, I don't know why the Clearpad touchscreen is enabled for the C6833, but not for the C6843; I think it's just garbage (perhaps they made the togari defconfig based off honami, and corrected that when making the togari_brazil defconfig). It doesn't make any difference for me, disabling them keep the touchscreen (MAX1187) functions normal.
Well, back to the point: even when applying these differences to the ZU DooMKernel, the digital TV doesn't work. The app stays a long time in a black screen, and finally closes (FC). I investigated the kmsg and logcat, but nothing useful.
CONFIG_DVB_CORE is "m" by default. I tried insmod'ing every module in /system/lib/modules, but same result. I temporarily gave up, because I don't watch the crap they broadcast on the open TV here. But yeah, it would be good to have everything working...

I hadn't got around to diff'ing them I just noticed the DVB line and had a quick look at the brazil defconfig.
I guess there is a binary blob that is needed?
For some reason I have to include the clearpad stuff at the moment in the pimped kernel, I should dig to find out why so the kernel is a tad smaller.

Hmm very good insight about the binary blob... It's very possible. I have FTFs for the C6833 and C6843, I'll extract them and compare the file list.
I made it work!! Well, involves some manual steps, but it's a very good progress. I started by comparing the file listing in /system from stock C6833 and C6843 firmwares, and although there is no kernel blob, there ARE some files related to DTV, mostly dynamic libs (.so), some configuration, but most importantly, these two:
Code:
/system/bin/dtvsdserver
/system/bin/dtvserver
So, I insmod'ed every module related to DTV/DVB, and then started these guys... And the TV works! BUT, as soon as I quit the Mobile TV app, the process "dtvserver" is killed with a hangup signal, and opening the app again does not restart it, so I have to manually bring the dtvserver up first (otherwise the same previous issue happens, black screen and finally Mobile TV FC's).
I notice some DTV/DVB modules couldn't be insmod'ed:
Code:
insmod: init_module 'dib3000mc.ko' failed (No such file or directory)
insmod: init_module 'dib7000m.ko' failed (No such file or directory)
insmod: init_module 'dib7000p.ko' failed (No such file or directory)
insmod: init_module 'dib8000.ko' failed (No such file or directory)
insmod: init_module 'dib9000.ko' failed (No such file or directory)
insmod: init_module 'mpq-dmx-hw-plugin.ko' failed (No such file or directory)
insmod: init_module 'tuner-simple.ko' failed (No such file or directory)
But the modules are there, and they are the new ones... I don't get it why they can't be insmod'ed, perhaps something is missing from the kernel config? It could be one of the reasons.
Another thing I've been wondering, is why the DVB modules necessary for the Mobile TV are not loaded automatically, like the wlan module is, for instance. Perhaps a difference in the ramdisk? Something to investigate next.

Congrats on getting that far with the DTV, will make for a more complete device for the c6843 users that want to use custom ROMs
Any differences in udev or init.rc or whatever android uses?
Development using the GPL and GPL'd code
The GPL is a very powerful tool, as are the other OSS licences. One has to know how they are used and can/can't be enforced before publishing any code under these licences or modifying code that that been published under a OSS licence. Using a OSS licence brings with it risks and rewords, often these are one and the same.
When we do anything with Android [Linux] kernels we fall under the bounds of the GPL v2 that it is published under. Any modification to the kernel has to be published under the same licence, and we have to publish the newly modified source in a sate that can recreate the binary that you publish to the public/xda.
I'll leave you with this quote from http://programmers.stackexchange.com
...are you prepared to live by it, and let other people use what you've written, rather than just liking it because of what you can get out of it?

F2FS mount and sysfs options
Now that we have an F2FS-enabled firmware by default, I've been reading about the mount options and sysfs entries available. As many of us know, there are lots of tweaks out there for EXT4, but what about F2FS? Well, here is the official documentation from the Linux kernel:
https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
As for the mount options, I think only discard could be interesting (but it's questionable, some people say it's better to schedule a regular fstrim call instead). There are also some sysfs tunables which I think can have a noticeable impact in battery life, and performance. Testing them would require a lot of trial and error. I'm pasting them below for those who don't want to go through the full document:
Code:
================================================================================
SYSFS ENTRIES
================================================================================
Information about mounted f2f2 file systems can be found in
/sys/fs/f2fs. Each mounted filesystem will have a directory in
/sys/fs/f2fs based on its device name (i.e., /sys/fs/f2fs/sda).
The files in each per-device directory are shown in table below.
Files in /sys/fs/f2fs/<devname>
(see also Documentation/ABI/testing/sysfs-fs-f2fs)
..............................................................................
File Content
gc_max_sleep_time This tuning parameter controls the maximum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_min_sleep_time This tuning parameter controls the minimum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_no_gc_sleep_time This tuning parameter controls the default sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_idle This parameter controls the selection of victim
policy for garbage collection. Setting gc_idle = 0
(default) will disable this option. Setting
gc_idle = 1 will select the Cost Benefit approach
& setting gc_idle = 2 will select the greedy aproach.
reclaim_segments This parameter controls the number of prefree
segments to be reclaimed. If the number of prefree
segments is larger than the number of segments
in the proportion to the percentage over total
volume size, f2fs tries to conduct checkpoint to
reclaim the prefree segments to free segments.
By default, 5% over total # of segments.
max_small_discards This parameter controls the number of discard
commands that consist small blocks less than 2MB.
The candidates to be discarded are cached until
checkpoint is triggered, and issued during the
checkpoint. By default, it is disabled with 0.
ipu_policy This parameter controls the policy of in-place
updates in f2fs. There are five policies:
0: F2FS_IPU_FORCE, 1: F2FS_IPU_SSR,
2: F2FS_IPU_UTIL, 3: F2FS_IPU_SSR_UTIL,
4: F2FS_IPU_DISABLE.
min_ipu_util This parameter controls the threshold to trigger
in-place-updates. The number indicates percentage
of the filesystem utilization, and used by
F2FS_IPU_UTIL and F2FS_IPU_SSR_UTIL policies.
max_victim_search This parameter controls the number of trials to
find a victim segment when conducting SSR and
cleaning operations. The default value is 4096
which covers 8GB block address range.
dir_level This parameter controls the directory level to
support large directory. If a directory has a
number of files, it can reduce the file lookup
latency by increasing this dir_level value.
Otherwise, it needs to decrease this value to
reduce the space overhead. The default value is 0.
ram_thresh This parameter controls the memory footprint used
by free nids and cached nat entries. By default,
10 is set, which indicates 10 MB / 1 GB RAM.

I'm giving it a try - downloaded the latest sources from CodeAurora and applied to your kernel (adjusting Kconfigs, Makefiles and defconfig). The compilation stops here:
Code:
drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.c: In function ‘wlan_hdd_send_avoid_freq_event’:
drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.c:574:18: warning: assignment makes pointer from integer without a cast
error, forbidden warning: wlan_hdd_cfg80211.c:574
make[3]: *** [drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.o] Error 1
OK, so I edited wlan_hdd_cfg80211.c and changed line 574 to add an explicit cast:
Code:
vendor_event = (struct sk_buff *)cfg80211_vendor_event_alloc(pHddCtx->wiphy,
Then it passes by this point, but stops in following lines with similar errors (not even pasting here). What I noticed from these errors it that CodeAurora's sources seem to be incompatible with Sony's kernel, because for instance, the function cfg80211_vendor_event_alloc is not defined anywhere (ran a grep over all *.c and *.h files in the kernel).
Comparing with a CM11 kernel, this function is also not defined anywhere, but the prima sources are very different, they don't call it. So I thought: let's use CM11's prima sources.
Bingo!
Compiled fine, booted, and with the correspoding firmware in /system/etc/firmware/wlan/prima, WLAN came up normally after boot. :victory:
Now you mentioned something about CM11's prima sources, from what I understood they are not ideal. Is that true? Because there are CM11-based custom kernels which implement intelliplug (dependent on custom WLAN drivers), for instance.
Hope it works for you. In this case, I'll put together a more organized how-to of what I did.

great!
can you just fork my repo and shift to the branch which worked for you, then send pull request? i will investigate on the Z1...
and yes please do send the steps!
well if we get custom compiled WLAN modules properly working on custom compiled kernel for stock ROM then i can have features like intelli-plug, F2FS, AsyncFS and lots more on stock ROMs!

Well I'm still learning my way around git & GitHub, so I think it will be faster if you just reproduce the steps below:
1) Copy Prima WLAN sources from CM11-based kernel:
I copied from SlimRom's kernel source. Put the sources under drivers/staging/prima.
2) Modify related Kconfig and Makefile:
drivers/staging/Kconfig
Code:
131,132d130
< source "drivers/staging/prima/Kconfig"
<
drivers/staging/Makefile
Code:
58,59d57
< obj-$(CONFIG_PRIMA_WLAN) += prima/
< obj-$(CONFIG_PRONTO_WLAN) += prima/
3) Modify defconfig:
I'm pasting every option related to WLAN. The Prima options should appear after a "make menuconfig".
Code:

/system/etc/firmware/wlan/prima
Code:
WCNSS_cfg.dat
WCNSS_qcom_cfg.ini

5) Include wlan.ko in kernel ZIP file:
Actually I include every compiled kernel module, because we are using a different toolchain and they may benefit from it too. Remember that /system/lib/module/wlan.ko is a symlink, but in my test the target got updated accordingly.

The branch from your kernel was master_kk-4.4.2. The Prima WLAN sources were, as I mentioned, from SlimRom's kernel, branch kk4.4.

Wow this is very nice! Follows the same line of research I've been doing, but this is more "elegant" and in-depth, especially because of all the benchmarks and other comparisons he has done. I'll try this approach myself on my custom builds.
One thing I noticed is that we may still have to use the "hammer" approach with the find & replace of the "-O" flags in *.mk and Makefiles I've been doing, because some of them have these flags hardcoded (i.e. they don't take the value from core/combo/TARGET_linux-arm.mk or other base files). I'll tip JustArchi in his thread about it.
Hi guys, I posted this in the general android section and have had no answer, maybe some one here might know?
I'm trying to build AOSP using CM 11's device tree for togari/togari_gpe and have hit a brick wall after solving the first few make errors.
I have to errors, that I suspect are the same problem:
The first is if I just build with make I get this error:
Code:

and if I do make bootimage I get this:
Code:
make: *** No rule to make target `out/target/product/togari/kernel', needed by `out/target/product/togari/boot.img'. Stop.
I suspect that both stem from aosp not finding the kernel source?
kernel source is at ~/dev/aosp/kernel/sony/msm8974/ and I'm building in ~/dev/aosp
I'm also trying to build vanir aosp using the same device tree and kernel and make bootimage completes fine.
Any help would be great
Yo, @DooMLoRD, @blueether @dbolivar
You guys have probably registred that Geohot (iPhone, PS3 jailbreaker) has successfully rooted the Galaxy S5 (and can now claim the $18,000 bounty), but i just read that this one-click root tool should work on any device running a pre-June 3rd kernel, i.e Android 4.4.2. The question is, does it work on the Ultra? I'm aware that it's easy to root an UItra AS LONG as the bootloader is unlocked, but this thing circumvents that part, and roots it. I think.
Are there anyone here still left on 4.4.2 that can try?
