[PATCH ghak59 V2 0/6] audit: config_change normalizations and event record gathering

Make a number of changes to normalize CONFIG_CHANGE records by adding missing op= fields, providing more information in existing op fields and connecting all records to existing audit events. The user record patch is included but is *optional* since there is doubt that we want to disconnect the records from a single event. Since tree purge records are processed after the EOE record is produced, the order of operation of the EOE record and the purge will have to be reversed so that the purge records can be included in the event. For reference, here are the calling methods and function tree for all CONFIG_CHANGE events: - audit_log_config_change() "op=set" - AUDIT_SET:AUDIT_STATUS_PID - AUDIT_SET:AUDIT_STATUS_LOST - audit_do_config_change() - AUDIT_SET:AUDIT_STATUS_FAILURE - AUDIT_SET:AUDIT_STATUS_ENABLED - AUDIT_SET:AUDIT_STATUS_RATE_LIMIT - AUDIT_SET:AUDIT_STATUS_BACKLOG_LIMIT - AUDIT_SET:AUDIT_STATUS_BACKLOG_WAIT_TIME - audit_log_common_recv_msg() - AUDIT_*USER* events (not CONFIG_CHANGE like all the rest) - AUDIT_LOCKED "op=%s_rule"(add/remove) - AUDIT_TRIM "op=trim" - AUDIT_MAKE_EQUIV: "op=make_equiv" - AUDIT_TTY_SET: "op=tty_set" - audit_log_rule_change() - AUDIT_ADD_RULE -F dir=: - AUDIT_DEL_RULE -F dir=: - audit_mark_log_rule_change() - audit_autoremove_mark_rule() "op=autoremove_rule(mark)" - audit_mark_handle_event() - audit_mark_fsnotify_ops.handle_event - audit_tree_log_remove_rule() "op=remove_rule(tree:%s)" from kill_rules() - from trim_marked() - AUDIT_TRIM: audit_trim_trees() "trim" - audit_add_tree_rule() iterate_mounts err "add" - audit_add_rule() - audit_rule_change() - AUDIT_ADD_RULE -F dir=: - AUDIT_MAKE_EQUIV: audit_tag_tree() iterate_mounts err "equiv" - from audit_kill_trees() - __audit_free() "free" - do_exit() - copy_process() err - __audit_syscall_exit() "exit" - from evict_chunk() "evict" - audit_tree_freeing_mark() - audit_tree_ops.freeing_mark - audit_watch_log_rule_change() - audit_update_watch() "updated_rules(watch:inval)" : "updated_rules(watch:set)" - audit_watch_handle_event() FS_CREATE|FS_MOVED_TO, FS_DELETE|FS_MOVED_FROM - audit_watch_fsnotify_ops.handle_event - audit_remove_parent_watches() "remove_rule(watch:parent)" - audit_watch_handle_event() FS_DELETE_SELF|FS_UNMOUNT|FS_MOVE_SELF - audit_watch_fsnotify_ops.handle_event See: https://github.com/linux-audit/audit-kernel/issues/50 See: https://github.com/linux-audit/audit-kernel/issues/59 Changelog: v2: - re-order audit_log_exit() and audit_kill_trees() - drop EOE reordering patch - rebase on 4.18-rc1 (audit/next) Richard Guy Briggs (6): audit: give a clue what CONFIG_CHANGE op was involved audit: add syscall information to CONFIG_CHANGE records audit: exclude user records from syscall context audit: hand taken context to audit_kill_trees for syscall logging audit: kill trees before logging syscall exit for exit/free audit: extend config_change mark/watch/tree rule changes kernel/audit.c | 20 ++++++++++++++------ kernel/audit.h | 4 ++-- kernel/audit_fsnotify.c | 4 ++-- kernel/audit_tree.c | 28 +++++++++++++++------------- kernel/audit_watch.c | 8 +++++--- kernel/auditfilter.c | 2 +- kernel/auditsc.c | 9 ++++----- 7 files changed, 43 insertions(+), 32 deletions(-) -- 1.8.3.1
