Description François Valenduc 2008-08-17 06:51:19 UTC 
Latest working kernel version: 2.6.27-rc3-git3
Earliest failing kernel version: 2.6.27-rc3-git4
Distribution: Gentoo
Hardware Environment: Packard Bell Easynote MB86, SMP, Intel Core2 Duo

Problem Description:

Steps to reproduce: try to compile the kernel

When I compile the last git version of kernel 2.6.27-rc3 (git4), I get the following compile error:

In file included from arch/x86/kernel/ptrace.c:19:

  CC      arch/x86/kernel/ptrace.o

In file included from arch/x86/kernel/ptrace.c:19:

include/linux/security.h: In function ‘security_ptrace_traceme’:

include/linux/security.h:1760: erreur: ‘parent’ undeclared (first use in this function)

include/linux/security.h:1760: erreur: (Each undeclared identifier is reported only once

include/linux/security.h:1760: erreur: for each function it appears in.)

After running a bisection, it appears that the commit 	5cd9c58fbe9ec92b45b27e131719af4f2bd9eb40 (security: Fix setting of PF_SUPERPRIV by __capable()) is problematic.

If I revert it, the kernel can be compiled.
