[tracker] Task opened: Websocket module leaks tcp connection buffers

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Hugh Waite (hugh.waite) Attached to Project - sip-router Summary - Websocket module leaks tcp connection buffers Task Type - Bug Report Category - tcp Status - Unconfirmed Assigned To - Operating System - All Severity - Low Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - The websocket module uses the tcpconn_get function when it needs to lookup the tcp connection from a websocket connection structure. The tcpconn_get function increases to reference count of the connection, and the structure, including the buffer, is not freed while this count is positive. I have tried solve this by adding a tcpconn_put function at the end of each function that did a get, but the system is still leaking buffers. These buffers are not visible in the tcp.dump output because the connection has been closed, but they can be seen in a memory dump (the buffer is 1MB on our system) More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=326 You are receiving this message because you have requested it from the Flyspray bugtracking system.

new features: dns operations in config file

by Daniel-Constantin Mierla

Hello, I added several functions and a new pseudo-variable class to ipops module that allow to do operations with dns directly from configuration file. One functionality is related to matching an IP address to a hostname. The hostname is resolved via a DNS query and then the IP is matched against the result set. There are two versions of this function, one using the system resolver and the other using the internal dns resolver, see: - http://kamailio.org/docs/modules/devel/modules/ipops.html#ipops.f.dns_sys_m… - http://kamailio.org/docs/modules/devel/modules/ipops.html#ipops.f.dns_int_m… Another enhancement is the possibility to store the result of a system dns query in a variable container and access the values from the config file - the function for the query is dns_query(hostname, pvid): - http://kamailio.org/docs/modules/devel/modules/ipops.html#ipops.f.dns_query The result is stored in $dns(pvid=>key) variable - you can see details about what keys can be used as well as an example at: - http://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#dns_pvid_key_-… The system dns queries use getaddrinfo() C function, resolving both to IPv4 and IPv6.

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#319 - Possible memory leak in srdb1 User who did this - Daniel-Constantin Mierla (miconda) ---------- I checked and the column name is not allocated dynamically by kamailio, but points to a structure to underline db lib. I looked at db_mysql and db_postgres. For example with postgres, the column is set with: /* The pointer that is here returned is part of the result structure. */ RES_NAMES(_r)[col]->s = PQfname(CON_RESULT(_h), col); RES_NAMES(_r)[col]->len = strlen(PQfname(CON_RESULT(_h), col)); Now, looking at postgres lib manual: PQfname - Returns the column name associated with the given column number. Column numbers start at 0. The caller should not free the result directly. It will be freed when the associated PGresult handle is passed to PQclear. Therefore kamailio should not free RES_NAMES(_r)[col]->s. If you think is different, provide more details of how you consider that RES_NAMES(_r)[col]->s is allocated dynamically by kamailio. ---------- More information can be found at the following URL: https://sip-router.org/tracker/index.php?do=details&task_id=319#comment1008 You are receiving this message because you have requested it from the Flyspray bugtracking system.
