pcre's behavior is changed so that pcre2_match always allocates heap for match_data, rather than stack, regardless of size. The heap isn't freed until explicitly calling pcre2_match_data_free. This new behavior may result in heap overhead, which may increase the peak memory usage about a few megabytes. It's because regex_match is first called for regex_data objects, and then regex_data objects are freed at once. To workaround it, free match_data as soon as we call regex_match. It's fine because libselinux currently doesn't use match_data, but use only the return value. Signed-off-by: Inseob Kim <inseob@google.com> Acked-by: Jason Zaman <jason@perfinion.com> |
