I'm facing a kernel build issue with the latest kernel on my machine. It seem
like a configuration issue, and I haven't been able to resolve it for sometime,
hence need your help. The error message is as below:
<error snip>
ERROR: "copy_from_user_overflow" [net/core/pktgen.ko] undefined!
ERROR: "copy_from_user_overflow" [fs/binfmt_misc.ko] undefined!
ERROR: "copy_from_user_overflow" [drivers/staging/cxt1e1/cxt1e1.ko] undefined!
ERROR: "copy_from_user_overflow" [drivers/isdn/icn/icn.ko] undefined!
ERROR: "copy_from_user_overflow" [drivers/isdn/hardware/avm/b1.ko] undefined!
<error snip>
The subroutine "copy_from_user_overflow" is defined in lib/usercopy.c, and the
'Makefile' in the lib directory looks something like this:
<snip from lib/Makefile>
lib-$(CONFIG_ARCH_HAS_DEBUG_STRICT_USER_COPY_CHECKS) += usercopy.o
<snip from lib/Makefile>
I think that this config option should be a built-in ('y') and I see that this
config option is indeed set to 'y' in the .config file.
<snip from .config>
amit at ubuntu:~/linux-next/linux-next$ grep
CONFIG_ARCH_HAS_DEBUG_STRICT_USER_COPY_CHECKS .config
CONFIG_ARCH_HAS_DEBUG_STRICT_USER_COPY_CHECKS=y
<snip from .config>
So what am I missing here ?

So now my .config file looks something like this: amit at ubuntu:~/linux-next/linux-next$ egrep -i 'pktgen|binfmt_misc|cxt1|isdn' .config # CONFIG_BINFMT_MISC is not set # CONFIG_NET_PKTGEN is not set # CONFIG_ISDN is not set # CONFIG_CXT1E1 is not set I didn't face any issue with the build now and while trying to boot from this newly built kernel, I found myself hopelessly staring at the screen, which seem to have stuck in the boot process. I think the kernel configuration file and the boot screenshot can be helpful for inspecting this boot issue. But before attaching these small files(136K and 32K respectively) and send it to the mailing list, I'd like to ask, if that's fine with you folks.

With these particular settings, I'm able to build the kernel, but still not able to boot from it: $ egrep -i 'pktgen|binfmt_misc|cxt1|isdn' .config CONFIG_BINFMT_MISC=y # CONFIG_NET_PKTGEN is not set # CONFIG_ISDN is not set # CONFIG_CXT1E1 is not set Just to be a little more verbose, I've listed below the steps that I follow to build and boot from the newly built kernel on my ubuntu box: $ sudo apt-get install build-essential $ make oldconfig $ make -jX all ;;Where X= Number of CPU cores $ sudo make modules_install install $ sudo update-grub $ sudo shutdown -y now [1] https://docs.google.com/folder/d/0B4un01St9Hdsb18xYU1yaF9ET0U/edit?usp=sharing Please let me know if you face any problem in accessing these. -Amit ^ permalink raw reply [flat|nested] 19+ messages in thread

You welcome. BTW, (fortunately you already done so), it's better to retest against latest linux-next tree. because possibly you hit a corner case error. And also if it's still possible, test against latest stable. That way. you will get better coverage on what's really going on. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com ^ permalink raw reply [flat|nested] 19+ messages in thread

Kernel config alone usually can't help much I'm trying this on a Virtual Machine using VMware Player. When the VM boots up, it throws lots of messages on the console and then gets stuck. I'd like to know, how I can capture all those console logs till it hits the hung point. -Amit ^ permalink raw reply [flat|nested] 19+ messages in thread

You just need to learn how to use its serial console.....or just use its ncurses display so you simply copy and paste from your terminal program. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -------------- next part -------------- An HTML attachment was scrubbed...
