[Q] (HELP) Cannot allocate TUN/TAP dev dynamically - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I want to use OpenVPN with Kebrum settings, but when i sellect kebrum.UDP.ovpn appears: FATAL: Cannot allocate TUN/TAP dev dynamically
I have bootloader locked, and Real ICS R6

probably its the kernel. stock sony kernel doesn't have tun driver for openvpn.

Moved to Q&A

[Q] Netfilter & iptable

Is there any way to compile the new 2.1 kernel with netfilter enable ?
No one ?
bootloader needs to be cracked...

[Q] 2.3.3 Kernel port

I found this in the X10 forum http://developer.sonyericsson.com/cws/download/1/938/364/1299757634/3.0.A.2.181_182.tar.bz2 ... They are the uncomplied Xperia Play open source files. I noticed there was a kernel folder, and my question is quite simply.
Is there any way to port this kernel?
I figured that this should be possible since i assume that these files are compatible with and also signed for the S1 bootloader. Although this is only me guessing
nope wont work, you need to compile kernel and then sign it. unless xperia play would use exact! same kernel config and drivers you would be able to use the play kernel. but unfortunately its not so we can not sign it

How to build a Linux kernel and flash it to the phone {from SE Dev Blog}

WOW! i couldnt believe that SE would be so open about this...
this info was released by SE Developer Blog... and i must say its very good info for developers (especially those who are working on custom kernel development)...
How to build a Linux kernel and flash it to the phone
it seems to be specifically for Xperia 2011 lineup devices but i think some components can be used even for X10...
something very interesting:
"The ARM cross-compiler. A cross-compiler is used to build ARM binaries on a different architecture, such as x86. This allows you to compile software (such as the kernel) into a format that the device can run. We recommend getting the CodeSourcery Lite compiler, especially the GNU/Linux variant, as you’ll need that if you want to build binaries for a full-blown Linux system on the device later. However, any EABI ARM compiler capable of compiling the Linux kernel should be enough for this step."
one of the SE devs actually posted this on Xperia Arc Android Dev thread:

Being not one of the newer se devices
Note: Replace/opt/arm-2010q1 with where you installed your cross-compiler. Also, this example is for Xperia™ PLAY. Replacedefconfig with the following values depending on what device you want to configure it for: Xperia™ PLAY semc_zeus_defco Xperia™ arc semc_anzu_defco Xperia™ neo semc_hallon_defco
What is the solution

need some help..
to configure x10i kernel what do i replace deconfig with?
eg: zeus for Play ; anzu for Arc..what for x10i..?
thnx in advance..

its not that straightforward... u will have to trace this defined variable among all files and check the corresponding configuration values...
also the latest Xperia devices are based on QSD8255 SoC chipset... our X10 is based on QSD8250 (older generation Snapdragon)... so u will have to search for QSD8250 specific config (values of variables) to compile this...
u can check the 2.6.29 kernel sources for X10 to get QSD8250 specific config/codes...
EDIT:
btw the kernel in latest Xperia devices is 2.6.32
for starters u can just try compiling 2.6.29 kernel released by SE for X10
FreeXperia project is already working on modded 2.6.29 kernel and they have plans for porting 2.6.32 for X10... so if u have some experience in compiling kernels/porting kernels between devices then contact jerpelea

[Q] Openvpn on FreeKernel mod 3.50

I'm currently using erickwill's EWJet rom, he switched to a different kernel and I want to install openvpn to it. The problem is I have the tun.ko from the stock kernel and when I try to do insmod it said I need a module that uses .o format like tun.o. I tried to do without the tun.ko but there was an error, unable to dynamically allocate TUN/TAP... something like that. I forgot because I switched back to the old rom. If there's an already compiled version of the tun module for the new kernel please show me the link because I've tried to search and couldn't find a new one. Please provide me the new tun module for the FreeKernel mod 3.50. thanks
pm jimbo..he can do the math

(Dev request)Overclocking without custom kernel

I have heard of some devices like SE W8 phone in which by overwriting some .ko files with root permit you can have overclock without bootloader unlock .... if possible can any dev here do that for our novathor phones
Xpetia P,U,Go and Sola are different devices (2012) then the w8 so no not possible !!

While building we have to edit arch/arm/mach-msm/acpuclock-7×30.c from the kernel source and therefore we have to make custom kernels. We may somehow be able to add governor and i/o schedulers modules on locked bootloader but as of now I don't think changing CPU clock speed is possible(correct me if I'm wrong). The 2010 phones are lot different and maybe they are also able to flash even custom kernels on locked bootloader via ftf format since it bypasses the sony signature verification which is not possible in 2012 phones.
tl;dr- Not possible
Cheers,

Thanks for the comprehensive answers .... btw if you can also solve my doubt abt any way of updating mali drivers without building a new kernel (cuz i am not a dev)
