When the user specifies a directory to delete with the suffix '/', the audit record fails to collect the filename, resulting in the following logs: type=PATH msg=audit(10/30/2024 14:11:17.796:6304) : item=2 name=(null) type=PATH msg=audit(10/30/2024 14:11:17.796:6304) : item=1 name=(null) It happens because the value of the variables dname, and n->name->name in __audit_inode_child() differ only by the suffix '/'. This commit treats this corner case by handling pathname's trailing slashes in audit_compare_dname_path(). Steps to reproduce the issue: # auditctl -w /tmp $ mkdir /tmp/foo $ rm -r /tmp/foo/ # ausearch -i | grep PATH | tail -3 The first version of this patch was based on a GitHub patch/PR by user @hqh2010 [1].
