Group the audit parameters for each task into one structure. In particular, remove the loginuid and sessionid values and the audit context pointer from the task structure, replacing them with an audit task information structure to contain them. Use access functions to access audit values. Note: Use static allocation of the audit task information structure initially. Dynamic allocation was considered and attempted, but isn't ready yet. Static allocation has the limitation that future audit task information structure changes would cause a visible change to the rest of the kernel, whereas dynamic allocation would mostly hide any future changes. The first four access normalization patches could stand alone. Passes audit-testsuite. Richard Guy Briggs (5): audit: normalize loginuid read access audit: convert sessionid unset to a macro audit: use inline function to get audit context audit: use inline function to set audit context audit: collect audit task parameters MAINTAINERS | 2 +- include/linux/audit.h | 30 ++++++++++--- include/linux/audit_task.h | 31 ++++++++++++++ include/linux/sched.h | 6 +-- include/net/xfrm.h | 4 +- include/uapi/linux/audit.h | 1 + init/init_task.c | 8 +++- kernel/audit.c | 4 +- kernel/audit_watch.c | 2 +- kernel/auditsc.c | 82 ++++++++++++++++++------------------ kernel/fork.c | 2 +- net/bridge/netfilter/ebtables.c | 2 +- net/core/dev.c | 2 +- net/netfilter/x_tables.c | 2 +- net/netlabel/netlabel_user.c | 2 +- security/integrity/ima/ima_api.c | 2 +- security/integrity/integrity_audit.c | 2 +- security/lsm_audit.c | 2 +- security/selinux/hooks.c | 4 +- security/selinux/selinuxfs.c | 6 +-- security/selinux/ss/services.c | 12 +++--- 21 files changed, 129 insertions(+), 79 deletions(-) create mode 100644 include/linux/audit_task.h -- 1.8.3.1
