New issue 370 by [email protected]: Kernel compilation error when using
KSAN
https://code.google.com/p/address-sanitizer/issues/detail?id=370
What steps will reproduce the problem?
Step 1:
To instrument the kernel we need to use a custom GCC, which I have download
https://address-sanitizer.googlecode.com/files/gcc-r203101-snapshot.tar.gz
Step2:
download ksan patched kernel https://github.com/google/kasan
Step3:
Untar the gcc downloaded in step 1 and kernel in step 2
export GCC_KASAN=<path_to_gcc_base_directory>
Step4.
cd <kernel_base_directory>
make CC='$GCC_KASAN/bin/gcc' olddefconfig
make CC='$GCC_KASAN/bin/gcc' menuconfig
Enable ( Generalsetup -> CONFIG_SLAB ) and ( Kernel hacking -> Memory
Debugging -> CONFIG_ASAN )
Step5:
make CC='$GCC_KASAN/bin/gcc' -j<no.jobs>
by following above procedure after Step5 I have encountered below Error:

What is the expected output? What do you see instead?
I expect compiled kernel Image but I have received error in compile time
What version of the product are you using? On what operating system?
I am trying on X64
$ uname -a
Linux ls3 3.13.0-32-generic #57~precise1-Ubuntu SMP Tue Jul 15 03:51:20 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux
Please provide any additional information below.
I have tried compiling a small C program with the compiler downloaded form
https://address-sanitizer.googlecode.com/files/gcc-r203101-snapshot.tar.gz
$ gcc --param asan-globals=0 global.c -o global
cc1: error: invalid parameter ‘asan-globals’
I will provide any additional information if required, please give me a
hint to solve this error.
Thanks in advance
