here is another error on the latest available grsec patch :

[...]

can you post your .config and your ld version?

thanks, will be fixed in the next patch.

its the same with grsecurity-2.1.14-2.6.31-200909121839
any idea ?

[radegand]

I seem to be affected by the same issue:
CC init/version.o
LD init/built-in.o
LD vmlinux
ld: vmlinux: section .text lma 0x40001140 overlaps previous sections
ld: vmlinux: section `.text' can't be allocated in segment 0
ld: final link failed: Bad value
make: *** [vmlinux] Error 1

That's an x86 box - I've successfully compiled the kernel on two amd64 boxes and it seems to be running fine so far. All systems in questions are running hardened gentoo with glibc-2.10.1
ld version below:
# ld --version
GNU ld (GNU Binutils for Debian) 2.18.0.20080103

Thanks

Could you try the latest patch? Some changes were made to the linker script. If that still doesn't work, could you confirm for us that you can build a vanilla 2.6.31 kernel? It seems that the problem may be dependent upon the binutils version you're using, as I wasn't able to reproduce the problem here with binutils 2.18.50 or 2.19

Hi,
The latest patch did not work :(

It bailed out here:

CC arch/x86/kernel/pcspeaker.o
kernel/futex.c: In function 'exit_robust_list':
kernel/futex.c:2434: warning: 'next_pi' may be used uninitialized in this function
AS arch/x86/kernel/head_32.o
arch/x86/kernel/head_32.S: Assembler messages:

make[2]: *** [arch/x86/kernel/head_32.o] Error 1
make[1]: *** [arch/x86/kernel] Error 2
make: *** [arch/x86] Error 2

However - upgrading binutils to 2.19.1 did the trick and so far my x86 is running 2.6.31-grsec fine...thanks! :)

I've fixed two compile errors with the patch and uploaded updated versions. Is there anyone still using binutils 2.18 that can confirm they're still unable to build a working kernel?

-Brad

[final_inode]

Although with 2.19.1 it compiles,I'm getting a Kernel panic - not syncing: Out of memory and no killable processes...
on 2.6.31-grsec

I'm using the hardened profile "hardened/linux/x86/10.0"

No, the 2.6.31-grsec still fails to build against ld version 2.18

I have the same problem, can't compile.
the patch version grsecurity-2.1.14-2.6.31-200909171758.patch
binutils 2.18.50
kernel 2.6.31

here is the error:
CC init/version.o

LD vmlinux

Can you post your config?

-Brad

[ngsupb]

sure it is: http://vetala.org.ua/config

it is on 64 if it makes any difference.

[PaX Team]

sure it is: http://vetala.org.ua/config

2.19 linked this fine but that can be due to other reasons as well. in any case, could you stick a

Code: Select all

. = ALIGN(16);

just before the .init.data section in arch/x86/kernel/vmlinux.lds.S (similar to how .init.setup has one already) and see if it helps?
