kamailio fail to start when there are many records in DB in location or in pua table
by laura testi 06 Dec '11

06 Dec '11

Hi all, when there many records in DB tables like location(usrloc use write back mode), pua etc, kamailio fail to start by complaining "no pkg memory left" when try to load (restore) all records from DB to hashtable of location/pua. The share momory are allocated enough for the hashtable, but the default compilation of the PKG_MEMORY_SIZE is 4MB, which allow only restore several thousands records. I know I can increase the PKG_MEMORY_SIZE, but anyway there is a limitation which may fail to restore all records from DB during the startup of kamailio if it reach the limit of the number of records in DB. Is there anyway to reload the hashtable from table by doing query n rows a time and loop until non more result from DB? this will avoid the kamailio startup problem when there are many records in hashtable which are save also in DB. Thank you very much in advanced! Laura

[tracker] Task opened: textopsx:msg_apply_changes() can corrupt incoming TCP message buffer
by sip-router 30 Nov '11

30 Nov '11

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 - textopsx:msg_apply_changes() can corrupt incoming TCP message buffer Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - All Severity - High Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - The msg_apply_changes function in textopsx module creates a new request in pkg memory and copies it back into the main message parse buffer. When data has been read from a TCP stream, it may include more than one message. The buffer and pointers will be corrupted if the new request is larger, causing failure to parse the subsequent messages. More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=185 You are receiving this message because you have requested it from the Flyspray bugtracking system.

Memory corruption in textopsx
by Hugh Waite 30 Nov '11

30 Nov '11

Hi, I've discovered a bug within textopsx to do with msg_apply_changes. After creating the new request in pkg memory it is memcpy'ed back into msg->buf. This is a issue when more than one SIP message has been read from a TCP stream. If the new request is larger it will corrupt the following message. I don't know the best way to resolve this immediately, but I felt it was worth mentioning here as you are about to release 3.2.1. Best regards, Hugh Code path to recreate bug: Send in 3 requests very quickly on a TCP stream, this is read as a single block. tcp_read.c: tcp_read_req() first message is parsed. receive_msg() -> In the cfg, insert a header (e.g. Max-Forwards: 10), msg_apply_changes() and forward. More data exists in buffer, which is shifted to the start of the buffer, however this has been overwritten. Parse fails on second request.

git:3.1: dialplan: fix usage of avps in replacement expression
by Daniel-Constantin Mierla 30 Nov '11

Module: sip-router Branch: 3.1 Commit: 8371befc51d8a0db7e57e686a77d9e700f609239 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=8371bef… Author: Daniel-Constantin Mierla <miconda(a)gmail.com> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: Mon Oct 17 18:27:42 2011 +0200 dialplan: fix usage of avps in replacement expression - clone the replacement expression to shared memory before parsing it in order to have variables names available at runtime - most of variables should be safe to use now in replacement expressions, including avps with string name. This fixes FS#153 reported by Andrew Pogrebennyk - variables with dynamic name have no easy way to clone at this moment, thus avoid using them directly. Use instead avps or script vars ($var(...)), copying the value from initial variable to it. Variables pointing to sip message attributes are safe to use. --- modules/dialplan/dialplan.c | 101 ++++++++++++++++++------------------ modules/dialplan/dp_db.c | 122 +++++++++++++++++++++---------------------- modules/dialplan/dp_repl.c | 108 +++++++++++++++++++++----------------- 3 files changed, 170 insertions(+), 161 deletions(-) Diff: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commitdiff;h=837…
