[sr-dev] [tracker] Task opened: ndb_redis redisc_free_reply bug

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Vicente Hernando (vicente) Attached to Project - sip-router Summary - ndb_redis redisc_free_reply bug Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - All Severity - Critical Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - Due to ndb_redis redisc_free_reply function I created in redis_client.c file, a bug has appeared able to crash kamailio. In pv_get_redisc function in ndb_redis_mod.c these lines appear: if(rpv->reply==NULL) { rpv->reply = redisc_get_reply(&rpv->rname); if(rpv->reply==NULL) return pv_get_null(msg, param, res); } That means it stores old redisc_reply_t in rpv->reply and if it has been freed with redisc_free_reply function a segmentation fault would happen. I find three solutions: patch one changes if(rpv->reply==NULL) into if(1). Disadvantage is it will always have to search the reply using redisc_get_reply adding some overhead. patch two changes redisc_free_reply function and deletes only inner redisReply structure. So once a redisc_reply_t is created it could be reused, but never deleted. Another solution would be completely deleting redisc_free_reply function. In my opinion second and third approaches are the best. Any comments?
