Compatible cifs.ko

Can some one compile or point me to a cifs.ko that is compatible with the incredible. The ones I can find do not seem to be. Thanks in advance.
Interesting
http://linux.die.net/man/8/mount.cifs Not that I can help but if anyone wanted a quick reference.
Alot of the roms for other phones have it but its not compatible with out kernel. Is there a guide how to compile kernels? I made a couple in linux that worked. long ago..
here ya go...what app are you using to browse CIFS shares? I haven't tested this module, but just compiled it now.
Forgive me as I haven't actually tried this, but here is the 10,000 foot view:
At a minimum, you will need a linux system, with a gcc-arm cross compiler set up. I believe the android-sdk provides one. The version used by current kernels is gcc-4.4.4.
Then you will need the sources of the kernel you are running. The hydra kernel git tree is here: http://github.com/ejhart/Hydra-kernels.git , and the stock kernel sources are here: http://member.america.htc.com/download/RomCode/Source_and_Binaries/incrediblec_cc1c2268.tar.bz2
The hydra git tree doesn't seem to have a a working .config included, but this isn't so important if you are only building and installing kernel modules. From there, you'll need to configure the kernel in cross compiler mode, add the modules you want, and you will need to make sure the version magic string is identical to the kernel you are using. From there run make, and once the compile is finished, find the .ko 's you want, and push them to the /system/modules folder where you can insmod them.
Edit: You can use the .config from /proc/config.gz, didn't see it in there before.

I got one from another user but thanks do you still want me to try it? I mounted my share in a directory on the SDCARD so i can browse it with any file manager. I think any app that scans the sd card will also scan my server with about 8TB so that is a minor issue.
kernel compile guide
A guide for compiling kernels can be found here :
http://code.google.com/p/android-serialport-api/wiki/Htc
I not a techie and a newbie at any android development.
Since the guide is more or less a a set of instructions with no theory.
Got it to run, but not sure what I was doing.
Any assistance in provide either cifs.ko for the HTC Aria w/ kernel version :
liberty-2.6.29-21f066a6 or instructions on how to compile the module would be greatly
appreciated.
BTW - there an app on the store for automating the CIFS mount (CIFSManager

Note that the post you quote was from before the 2.2 OTA, and hence that cifs.ko would be incompatible with the current kernel.

Thanks for pointing that out. So does anyone have a compatible cifs.ko for the current DINC kernel?

[Q] How to compile bcm4329.ko module to N1

Dear All,
How can I compile bcm4329.ko module from source code to Nexus One?
I downloaded the latest android source code which includes the bcm4329 driver in the following directory:
/hardware/broadcom/wlan/bcm4329.
I simply run make under the root folder of anroid source code. It seems that /out/target/product/passion/system/lib/modules/bcm4329.ko is directly copied from /device/htc/passion-common/bcm4329.ko. The driver source code is not compiled at all. Could anyone please tell me how to build it separately? Thanks for any help!
Best,
Hao
Does anyone know? Appreciate any kind of hits!

i face the same problem as yours...do you have solved it??
i had to deal with this when i compiled my kernel before, but i honestly dont remember how to do it. i had to get help from some devs ultimately.

[KERNEL] Building additional modules for JB stock kernels

Some background info:
I'm the author of PPP Widget which is an app that enables mobile data connections on Android devices with USB host capabilities - even if they are WiFi-only.
It turned out that many Android devices have the drivers for 3G sticks already on board, included with the stock kernel. The one large exception are Samsung devices ...
I started to provide the missing drivers as modules (mostly "ppp_async" and "option" which depends on "usb_wwan"). That worked well for some Google devices and also for Samsung devices running ICS, using the source packages from
http://opensource.samsung.com/
In their JB kernels though, Samsung enabled the "MODVERSION" option. Furthermore, compiling the modules with the officially recommended toolchain resulted in a different "module_layout" checksum than in the modules provided in the firmware.
This prevents using any additonal modules on the devices. "insmod" refuses to load these modules.
The only explanation for this problem is that the custom device configuration provided in the source packages does not match the configuration of the device kernel.
This is the case for all GT-P31xx and GT-P51xx models as far as I can tell.
My take is that Samsung is required to provide the correct kernel configuration under the rules of the GPL. Maybe anyone else wants to contact Samsung on this behalf; I already did several times - still waiting for an answer ...
That's the reason why I build everyting from source including the GPU driver and lost exFAT support http://forum.xda-developers.com/showthread.php?t=1859227 and the boot image result http://forum.xda-developers.com/showthread.php?t=1855700 .

Unfortunately, replacing the kernel is no option for end users. The modules I provide are going into a folder on the sdcard, and can be "insmod'ed" from there with no problem - once their magic string and the "modversions" are matching the kernel on the device. The latter is the wall I'm hitting ...

Thanx alot for such a great development. ...

I have received a reply from Samsung. They have updated the JB open source package for GT-P3110, GT-P5110 and GT-N7100 (which previously included a config file from 3.0.15 for a kernel version of 3.0.31 !!).
Unfortunately, the modversions of the compiled kernel are still different and incompatible. I have replied with these finding.
Waiting again ...
BTW, the only recent kernel config consistent with the actual device kernel that I have found is for the GT-N8000 (3.0.31). So it is possible to provide a matching configuration.

If You will start to work with kernel I'm willing to beta test with my P5110. Only issue for me is that I need to know what 3G dongle to buy (well need it anyway so would prefer an advice from someone who know something about it). I'm living in Poland and Ireland (once here once there) so I can even test LTE modems (well donations here, myself can spend up to ~50€ on 3G one) because in Wroclaw, Poland I heard it's quite good, also I got H+/H on SGSII here. While in Ireland signal is not THAT strong due to fact most of places are quite remote (except Dublin, Galway etc). Hope I can help in either way
This is what I wrote to Samsung concerning the botched configuration file provided with the latest GT-P3110 kernel source:
Thank you for the source code update.
However, I have asked for the kernel configuration that matches exactly the kernel on the GT-P3110.
I have compiled the kernel from the provided update, but the module layout checksum does *not* match the one from the kernel running on my device.
On the device: module_layout 0xb5a27644
From source: module_layout 0x143474f1
I have used the recommended toolchain "CodeSourcery 2010q1" and the unchanged config file provided with the source ("android_espresso_omap4430_r04_user_defconfig").
Please be aware that you are obliged by the GPL to provide the correct config file for the binary kernel that you are distributing.
As a side note: the configuration provided with the kernel source for the GT-N8000 *does* match the kernel on the device, so there is no doubt that it is possible to get the configuration right.
Other Android vendors are just enabling the "embedded" config file in the kernel, so that the correct configuration is simply available on the device as "/proc/config.gz". This is so much less trouble. I suggest that you enable this option for Samsung kernels too.

...

The GT-N8010 is also in the same situation you describe - config for 3.0.15 and jb stock kernel at 3.0.31, can't build working modules for stock.
davp, there seems to have been some activity at the Samsung open source center after my messages.
I suggest you make yourself heard as well. Use the "Inquiry" button next to the package download link in the table for your device.
To be able to add working modules to the device, the kernel configuration for the source has to be 100% compatible. It does not matter if any closed drivers are missing as we don't want to replace the kernel - but all those general debugging config options should be correct.
BTW, there is a history of similar issues:
http://forum.xda-developers.com/showthread.php?t=1123643
The kernel source for the GT-P3110 has been updated once more, and this time they have fixed the configuration.
With the latest JB update we can actually build working modules for the current firmware.
I confirmed this to the Samsung people and reminded them of the other devices in need of this fix: GT-P3100, GT-P5100, GT-P5110, GT-N7100 and probably more (like the GT-N8010).

So for now we might get stock kernel which will support 3G modems via USB OTG? How about other kernels such as CM10.1?
I'm looking for good 3G dongle then Any advices?
Additional kernel modules for stock JB P31xx (tested) and P51xx (untested), contains:
- usb_wwan, ppp_async, and option module for PPP Widget
- dns_resolver, md4, and cifs module for cifs/samba filesystem support
- sunrpc, lockd, and nfs module for nfs filesystem support
Kernel config file attached.
FTDI Single Port Serial Driver added.

Hi ketut.kumajaya,
I'm trying to use cifs.ko but i get:
/system/lib/modules # insmod cifs.ko
insmod: can't insert 'cifs.ko': unknown symbol in module or invalid parameter
I have:
/system/lib/modules # uname -a
Linux localhost 3.0.31-1084989 #1 SMP PREEMPT Mon Mar 25 14:53:07 KST 2013 armv7l GNU/Linux
I tried other cirs.ko with same result.
Can you give me some clues of what can I do?
Thank you.
Try insmod in order:
insmod dns_resolver.ko
insmod md4.ko
insmod cifs.ko
If something goes wrong, see the kernel messages using dmesg.

Great!!!
That's the solution.
In my Tab 10.1 4.0.4 I'm loading (different kernel and different modules, of course):
insmod cifs.ko
insmod md4.ko
insmod nls_utf8.ko
So I was not thinking I should use a different order.
Thank you.

Wifi module in S5830 stock kernel.

Ok so I have compiled a kernel for S5830 just for testing. I have created the ZImage and then placed it in AnyKernel-Master.zip - kernel. Below attatched is the screenshot of AnyKernel-Master.zip structure. I need to make sure whether it is correct or not. Also I don't know the location of wifi module for galaxy ace. Any suggestions will be welcomed.
Anyone??

Samsung msm7x27 kernel contains ramdisk+zimage(=boot.img). So, that's not the correct format. I don't know for which version(2.3+ or 4+), but you should use proper ramdisk to boot respective android versions for ace. Check here for reference

For further details, pm me.
