[PATCH 0/2] security/smack implement logging V3

[Etienne Basset]

Hello,

the following 2 patches implements auditing of security events for Smack.

patch 1 : created common LSM auditing code 
patch 2 : convert smack to use it

Changes since V2 :
- don't make Smack depend on AUDIT
I tried to make it zero overhead in the !CONFIG_AUDIT case,
without making the code too ugly (??). I hope i didn't mess it too much
- makes everything a key=value pair
- various other cleanup suggested by Eric and Casey 

Change since V1 :
moves shareable code to include/linux/lsm_audit.h and security/lsm_audit.c.
Smack specific logging functions are now defined in smack_access.c


sample logs produced :
