[kamailio] rtpengine: hash table to keep the selected nodes (#390)
by Stefan Mititelu 10 Dec '15

10 Dec '15

Shared memory hash table with global hashtable lock. Add state maintaining the selected rtp node, for a given callid. Hashtable entry expiration time configurable using hash_entry_tout modparam. The actual deletion happens on the fly while insert/remove/lookup are called. Updated doku.

[kamailio] dialog's keepalives keep sending to old address after re-INVITE with updated location (#273)
by Andrey Utkin 10 Dec '15

10 Dec '15

Hi, we use pretty recent kamailio: ``` version: kamailio 4.4.0-dev2 (x86_64/linux) 1a758d flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 1a758d compiled on 14:49:47 Jul 20 2015 with gcc 4.8.2 ``` The case: consider the mobile SIP agent which switches between networks (e.g. wifi -> mobile) during the call. It sends re-INVITE with its new location. We use keep-alives provided by dialog module. And it seems that keep-alives don't use new address and are always sent to initial address. Any thoughts? Thanks. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/273

info: kamailio.org updates - letsencrypt for https and dkim for email
by Daniel-Constantin Mierla 09 Dec '15

09 Dec '15

Hello, during the past few days I made some updates related to the security aspects of kamailio.org services. Two are relevant for the community. 1) First, kamailio.org uses now a TLS certificate signed by letsencrypt.org, a free trusted CA backed up by Mozilla and other internet companies, so browsing via HTTPS should no longer issue any warning of untrusted certificate (previously we used a CACert.org certificate which was not trusted automatically by browsers). Wiki and mailing lists portals use the letsencrypt certificate as well, so is no reason not to browse all kamailio.org and lists.sip-router.org pages only via HTTPS. Perhaps in the near future we will try to enable redirect of HTTP to HTTPS at least for the main page and login pages for wiki, mailing lists and other places that require sensitive data. Now SSLLabs test ranks https://kamailio.org with grade A: * https://www.ssllabs.com/ssltest/analyze.html?d=kamailio.org&latest As a side note, for those that haven't noticed it, for quite some time kamailio.org is available also over IPv6. 2) Second, emails forwarded by kamailio.org and lists.sip-router.org are having now a DKIM signature. Also, there are SPF records in DNS for these domains. Hopefully, those two will help getting the emails to be allowed by various spam filters out there, as their legit origin can be checked. If you check the sources of an email messages and the email server of receiving party is doing DKIM/SPF checks, you should see some headers like next (taken from an email I received to my gmail account from sr-users mailing list): """ Authentication-Results: mx.google.com; spf=pass (google.com: domain of sr-users-bounces(a)lists.sip-router.org designates 193.22.119.66 as permitted sender) smtp.mailfrom=sr-users-bounces(a)lists.sip-router.org; dkim=pass header.i=(a)lists.sip-router.org DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=lists.sip-router.org; s=20151206; h=Sender:Content-Type:List-Subscribe:List-Help:List-Post:List-Archive:List-Unsubscribe:List-Id:Reply-To:Subject:MIME-Version:Message-ID:To:From:Date; bh=lGjvCZYcxBHUHaJDnut1j2YTyPsXTnXHzUb0CgcDc1Q=; b=DlD+MKoEqyISB5Ba775t3zg70FC6ouC+tEo7j5zv4dn2Dhm4pWqkQXSfU4Kp1NqW1ZRYFC/mpg/7LEcGW2FlDL9J0FpUg1VjNmN7D1wvtW08hBBw91tsXImu9yf7KZjg/p4IbXu6vznldubrSxweIaV3q/xbrLgaqP5Dsrvs/9A=; """ Kamailio is not enforcing any of those policies on received email messages, so sending to the lists should not be affected. Should anyone discover problems when browsing the web portals or notices issues with emails from our mailing lists, report them to sr-dev mailing list. Also, if anyone has more hints on increasing the security/privacy for the web server and email systems we run for kamailio.org, do not hesitate to provide us suggestions.

[kamailio] PDB module prefixes (#433)
by igorPot 09 Dec '15

09 Dec '15

Hi all, I had configured my pdb module to accept 5 number prefixes by modifying: In pdbt.c: bufsize = slen + 1 + 1 + 4 + 1 + 1; // line buffer (telephone number + colon + white space + carrier ID + newline + \0) ... ret = snprintf(p, 7, "%d\n", node->carrier); if (ret < 1 || ret > 6) { And in common.h: #define MAX_PDB_CARRIERID 99999 And i hadn't had any problem until now. I had rows in my .csv like: 0645052050;10122 And it worked. The problem I have now is with prefixes bigger than 40000. I get segmentation fault when doiong a query with pdbt, however the pdbt build works good without any error. At first i thought of a buffer problem but eventhough testing with a .csv of 2 rows with 50000 prefixes will not work. Another curious effect is that for a prefix like 84238 the server changes the answer to 18754. I dont know why... Could anyone help me please? Thanks. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/433
