[SR-Users] memory leak fix on xcap_ auth.c

Hi Daniel, I'm sending you some memory leak fix we have found and fixed on modules/utils/xcap_ auth.c. The fixed memory leak is in pres_watcher_allowed (), and it is about the "xmlFreeDoc" that it's never called for the "xcap_tree" variable. We downloaded the source file from master branch and then we fixed it. You can find here the diff from original and new code and in attach both the original and the new files. diff -u a/modules/utils/xcap_auth.c b/modules/utils/xcap_auth.c --- a/modules/utils/xcap_auth.c +++ b/modules/utils/xcap_auth.c @@ -280,13 +280,15 @@ } node= get_rule_node(subs, xcap_tree); - if (node== NULL) + if (node== NULL){ + xmlFreeDoc(xcap_tree); return 0; - + } /* process actions */ actions_node = xmlNodeGetChildByName(node, "actions"); if (actions_node == NULL) { LM_DBG("actions_node NULL\n"); + xmlFreeDoc(xcap_tree); return 0; } LM_DBG("actions_node->name= %s\n", actions_node->name); @@ -294,6 +296,7 @@ sub_handling_node = xmlNodeGetChildByName(actions_node, "sub-handling"); if (sub_handling_node== NULL) { LM_DBG("sub_handling_node NULL\n"); + xmlFreeDoc(xcap_tree); return 0; } sub_handling = (char*)xmlNodeGetContent(sub_handling_node); @@ -302,6 +305,7 @@ if (sub_handling == NULL) { LM_ERR("Couldn't get sub-handling content\n"); + xmlFreeDoc(xcap_tree); return -1; } if (strncmp((char*)sub_handling, "block", 5) == 0) { @@ -325,10 +329,12 @@ else { LM_ERR("unknown subscription handling action\n"); xmlFree(sub_handling); + xmlFreeDoc(xcap_tree); return -1; } xmlFree(sub_handling); + xmlFreeDoc(xcap_tree); return 0; Kind Regards, laura
