[Dovecot] quota_set leak

The quota plugin in 2.0.beta6 leaks 2KB "quota settings" pools. Here is a patch to plug this leak, assuming you intended the caller of quota_init to retain ownership of the quota_set. If on the other hand you intended for quota_init to assume ownership of the quota_set, then the quota_settings_deinit call belongs in quota_deinit. --- a/src/plugins/quota/quota-storage.c (beta6) +++ b/src/plugins/quota/quota-storage.c (patched) @@ -427,6 +427,7 @@ { struct quota_user *quser = QUOTA_USER_CONTEXT(user); + quota_settings_deinit(&quser->quota->set); quota_deinit(&quser->quota); quser->module_ctx.super.deinit(user); }
