Neither of these is an ET_DYN file; they are both ET_EXEC, so it *should* be unaffected by the PIE randomization patch. Obviously, that seems to not be the case.

I checked it by unpacking the initrd.img file. Notify also that I used git-bisect to identify the PIE patch. This requires successful builds. Reverting the patch clearly resolved the issue at the end. > Ulrich, did your initrd contain the correct .so? Sure! I have only one klibc-*.so on my box in /lib. I diffed the file in the unpacked initrd.img with the file in /lib and there has been no difference. I always recreate the initial ramdisk after the kernel rebuild with make install and my own installkernel script, which uses mkinitramfs. The mkinitramfs script ensures that the klibc so object from /lib and the klibc binaries from /usr/lib/klibc/bin are copied into the initrd image. Usually that works without any issue on x86, x86-64. PPC can't use make install, but I use mkinitramfs there too, which handles klibc the same way. > Did you try rebuilding klibc after building the new kernel?

However at the end busybox is called and then there is a shell, where I can call the binaries and force the segmentation violation. Pencil and paper work usually.

The message looks like: sleep[7888]: segfault at 000000000004001C rip 000000000004001C rsp 00007fff14776468 error 14 Repeated calls get the same message with the stack pointer changing. Other binaries (mount) have a segmentation fault at another addressi (0x400184). It appears that the instruction pointer fails at the start address of the klibc binary. Notify that this lies in the binary itself and not in the /lib/klibc*.so object, so it appears that the klibc binary sections are loaded at randomized addresses.

Hi Ulrich, I just now quickly tried to with klibc-1.5 on i386 with the PIE-randomization patched kernel, and it seems to load static libraries fine. I just downloaded klibc-1.5, built it, and executed a few of the programs in usr/utils/static, all of them worked. Does this also work for you and you are experiencing the problems solely when the binaries are being run from initramfs during boot? I will test more shortly (on x86_64, directly from initramfs) in order to reproduce. Thanks, -- Jiri Kosina SUSE Labs ^ permalink raw reply [flat|nested] 24+ messages in thread

Thanks, Here is the .config file. I used it directly with 60bfba7e8 and could reproduce the bug. (All other builds after the patch could also reproduce the bug.) I use klibc-utils 1.4.30-3ubuntu2 which depends on libklibc with the same version number. The processor is an Intel Core 2 Duo T5500 @ 1.66 GHz, if that helps. # # Automatically generated make config: don't edit # Linux kernel version: 2.6.22 # Wed Jul 25 07:48:18 2007 # CONFIG_X86_64=y CONFIG_64BIT=y CONFIG_X86=y CONFIG_GENERIC_TIME=y CONFIG_GENERIC_TIME_VSYSCALL=y CONFIG_ZONE_DMA32=y CONFIG_LOCKDEP_SUPPORT=y CONFIG_STACKTRACE_SUPPORT=y CONFIG_SEMAPHORE_SLEEPERS=y CONFIG_MMU=y CONFIG_ZONE_DMA=y CONFIG_RWSEM_GENERIC_SPINLOCK=y CONFIG_GENERIC_HWEIGHT=y CONFIG_GENERIC_CALIBRATE_DELAY=y CONFIG_X86_CMPXCHG=y CONFIG_EARLY_PRINTK=y CONFIG_GENERIC_ISA_DMA=y CONFIG_GENERIC_IOMAP=y CONFIG_ARCH_MAY_HAVE_PC_FDC=y CONFIG_ARCH_POPULATES_NODE_MAP=y CONFIG_DMI=y CONFIG_AUDIT_ARCH=y CONFIG_GENERIC_BUG=y #

In my case the buggy klibc worked fine with a stock 2.6.18 kernel, but broke when the execshield patch was applied - and the commit 60bfba7e code comes from execshield, so it looks like the same problem. > filesz 0x0000000000000100 memsz 0x0000000000004288 flags rw- > STACK off 0x0000000000000000 vaddr 0x0000000000000000 paddr 0x0000000000000000 align 2**3 > filesz 0x0000000000000000 memsz 0x0000000000000000 flags rwx > > Sections: > Idx Name Size VMA LMA File off Algn > 0 .text 0000da94 0000000000200200 0000000000200200 00000200 2**2 > CONTENTS, ALLOC, LOAD, READONLY, CODE > 1 .rodata 00003cde 000000000020dca0 000000000020dca0 0000dca0 2**5 > CONTENTS, ALLOC, LOAD, READONLY, DATA > 2 .data 00000100 0000000000411980 0000000000411980 00011980 2**5 > CONTENTS, ALLOC, LOAD, DATA > 3 .bss 00004188 0000000000411a80 0000000000411a80 00011a80 2**5 > ALLOC > 4 .gnu_debuglink 0000002c 0000000000000000 0000000000000000 00011a80 2**0 > CONTENTS, READONLY > SYMBOL TABLE: > no symbols > [-- Attachment #2: Type: application/pgp-signature, Size: 189 bytes --] ^ permalink raw reply [flat|nested] 24+ messages in thread

Bret -- could you please clarify whether you have experienced also klibc-related segfaults with pie-randomization.patch applied, or you have had just random binaries segfaulting, as you pointed out here: http://lkml.org/lkml/2007/7/21/31 Seems like you are also using ubuntu, same as Ulrich, so you might have been hitting the very same behavior of klibc-1.4. Thanks in advance for clarifying this, so that I can eventually resubmit the pie-randomization patch. Thanks, -- Jiri Kosina SUSE Labs ^ permalink raw reply [flat|nested] 24+ messages in thread
