If anyone has any objections, please let me know. ------------------ From: Zygmunt Krynicki [ Upstream commit 340372688bb87da45ff8d4e2f82ccfd1b64c65ff ] apparmor_secmark_init() parses a configured secmark label to obtain its secid. aa_label_strn_parse() returns a refcounted label, but the success path kept that reference after copying the secid.
