Hi James,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

In file included from init/main.c:35:
include/linux/security.h:1788: error: static declaration of 'security_capable' follows non-static declaration
include/linux/capability.h:524: error: previous declaration of 'security_capable' was here
include/linux/security.h:1793: error: static declaration of 'security_capable_noaudit' follows non-static declaration
include/linux/capability.h:525: error: previous declaration of 'security_capable_noaudit' was here

Caused by commit 06112163f5fd9e491a7f810443d81efa9d88e247 ("Add a new
capable interface that will be used by systems that use audit to").

Please compile test with and without CONFIG_SECURITY.

I have dropped the security-testing tree for today.

Only works in the config security case because every function that calls
has_capability() also includes security.h

Since these are inlined the original caller needs to have the
security_capable and security_capable_noaudit prototype.  The filesystem
changes to use this new interface often do not already #include
security.h.  I'll look at it and wrap them in CONFIG_SECURITY rather
than include security.h in all the filesystem changes.....

Hi James,

Today's linux-next build (powerpc pseries_defconfig) failed like this:

kernel/built-in.o: In function `.__audit_log_bprm_fcaps':
(.text+0x63aec): undefined reference to `.get_vfs_caps_from_disk'
kernel/built-in.o: In function `.audit_copy_inode':
auditsc.c:(.text+0x64594): undefined reference to `.get_vfs_caps_from_disk'

get_vfs_caps_from_disk() is protected by
CONFIG_SECURITY_FILE_CAPABILITIES but the call sites in kernel/auditsc.c
are not.

This error is still there today.  I will have to drop the
security-testing tree on Monday if this is not fixed.

I am aware.  James didn't like my first fix for CONFIG_AUDIT but not
CONFIG_SECURITY_FILE_CAPABILITIES so I just sent another one which
should address the concern.

Hi James,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

fs/namei.c: In function 'may_open':
fs/namei.c:1516: error: 'nd' undeclared (first use in this function)

This was also fixed before I pushed my tree out (can you re-pull the 
security-testing tree at ~11am your time if you get a conflict?  chances 
are I've fixed it by then).

Sorry, I thought I put the definitions outside of the ifdef in
security.h but clearly they aren't.  Looks like James's tree has the fix
as of a couple of hours ago, so you should be fix on your next pull from
him.

Hi ,

Today's linux-next build (sparc64 defconfig) failed like this:

cc1: warnings being treated as errors
include/linux/security.h:3012: error: 'security_key_session_to_parent' declared 'static' but never defined

Caused by commit ee18d64c1f632043a02e6f5ba5e045bb26a5465f ("KEYS: Add a
keyctl to install a process's session keyring on its parent [try #6]")
which I have reverted for today.

(I also reverted commit 945af7c3289c26c9070d6b1bf3ca759d36643e0b ("KEYS:
security_cred_alloc_blank() should return int under all circumstances")
which is a fix for the above commit.)

The avr32 defconfig build fails the same way as well.  Thee may be
others, that is as far as we have gone so far.

This also broke the alpha and mips builds.  I am going to use the version
of the security-testing tree from next-20090902 (the latest version I
have before the above commit was added) for today.
