audit: issue CWD record to accompany LSM_AUDIT_DATA_* records
The LSM_AUDIT_DATA_* records for PATH, FILE, IOCTL_OP, DENTRY and INODE are incomplete without the task context of the AUDIT Current Working Directory record. Add it. This record addition can't use audit_dummy_context to determine whether or not to store the record information since the LSM_AUDIT_DATA_* records are initiated by various LSMs independent of any audit rules. context->in_syscall is used to determine if it was called in user context like audit_getname. Please see the upstream issue https://github.com/linux-audit/audit-kernel/issues/96 Adapted from Vladis Dronov's v2 patch.
