Merge tag 'audit-pr-20200803' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit
Pull audit updates from Paul Moore:
"Aside from some smaller bug fixes, here are the highlights:
- add a new backlog wait metric to the audit status message, this is
intended to help admins determine how long processes have been
waiting for the audit backlog queue to clear
- generate audit records for nftables configuration changes
- generate CWD audit records for for the relevant LSM audit records"
* tag 'audit-pr-20200803' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
audit: report audit wait metric in audit status reply
audit: purge audit_log_string from the intra-kernel audit API
audit: issue CWD record to accompany LSM_AUDIT_DATA_* records
audit: use the proper gfp flags in the audit_log_nfcfg() calls
audit: remove unused !CONFIG_AUDITSYSCALL __audit_inode* stubs
audit: add gfp parameter to audit_log_nfcfg
audit: log nftables configuration change events
audit: Use struct_size() helper in alloc_chunk
