[PATCH 0/2] security/smack implement logging V2

[Etienne Basset <etienne.basset@numericable.fr>]

Hello,

the following 2 patches implements auditing of security events for Smack.
It tries to implement what Eric Paris suggested, and 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

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

the patches are against current mainline
thanks,
Etienne
