library dir for x86_64 - lib or lib64

by Daniel-Constantin Mierla

Hello, iirc this was at some point discussed, however, I want to go through it again. Many x86_64 distros expect libraries to be placed under a lib64 directory. For example the RPM spec file language returns /usr/lib64 for %{_libdir} variable. In the master branch I committed a patch that does this detection. As I saw some people saying that 'lib' should be the default also for x86_64, my question is then what do you think we should use? Using 'lib' will definitely make building rpms fail unless we do a patch specific for these distros. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

valgrind errors from 3.1-stable (git 2fe4d633e4ac)

by Timo Teräs

Hi all, I'm running 3.1-branch git head currently under valgrind. And I've seen several invalid reads and writes (apparently most are off by one). ==22274== Invalid read of size 1 ==22274== at 0x6DA2C0A: pv_set_ruri_user (pv_core.c:1755) ==22274== by 0x13BA15: lval_pvar_assign (lvalue.c:357) ==22274== by 0x13BF0F: lval_assign (lvalue.c:405) ==22274== by 0x139E4D: do_action (action.c:1472) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x12FDEB: do_action (action.c:711) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x13A86F: run_actions_safe (action.c:1607) ==22274== by 0x1E2666: rval_get_int (rvalue.c:904) ==22274== by 0x1E5252: rval_expr_eval_int (rvalue.c:1866) ==22274== by 0x131B8A: do_action (action.c:1071) ==22274== by 0x13A6F1: run_actions (action.c:1555) Is fairly obvious. modules_k/pv/pv_core.c has several places which take backup of "val->rs.s[val->rs.len]" and replaces it with zero for string termination. It's than later on set back to the original value. However, it would appear that the value passed does not always point to a memory area which is large enough. This results in multiple invalid reads and writes of one. The remaining reads are not so clear to me. ==22274== Invalid read of size 1 ==22274== at 0x4811A69: strncpy (mc_replace_strmem.c:339) ==22274== by 0x6DA77FF: set_var_value (pv_svar.c:122) ==22274== by 0x6DA1EDB: pv_set_scriptvar (pv_core.c:1636) ==22274== by 0x13BA15: lval_pvar_assign (lvalue.c:357) ==22274== by 0x13BF0F: lval_assign (lvalue.c:405) ==22274== by 0x139E4D: do_action (action.c:1472) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x131E05: do_action (action.c:1086) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x12FDEB: do_action (action.c:711) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x131E05: do_action (action.c:1086) ==22274== Invalid read of size 2 ==22274== at 0x4811E1F: memcpy (mc_replace_strmem.c:523) ==22274== by 0x1E134D: rval_new_str (rvalue.c:269) ==22274== by 0x1E394E: rval_convert (rvalue.c:1301) ==22274== by 0x1E4780: rval_str_add2 (rvalue.c:1610) ==22274== by 0x1E8681: rval_expr_eval (rvalue.c:2399) ==22274== by 0x13BBD9: lval_assign (lvalue.c:389) ==22274== by 0x139E4D: do_action (action.c:1472) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x12FDEB: do_action (action.c:711) ==22274== by 0x13A6F1: run_actions (action.c:1555) ==22274== by 0x139229: do_action (action.c:1342) ==22274== by 0x13A6F1: run_actions (action.c:1555) Any ideas how to fix these? Or any instructions what to provide more in the bug report? Cheers, Timo

RPM packages for Kamailio 3.1.2

by Daniel-Constantin Mierla

Hello, there is now a service on opensuse build server to create kamailio v3.1.2 (git branch 3.1.2) RPMs i586/x86_63 for Centos 5.5, RedHat 5, Fedora 14 and OpenSuse 11.4, you can check this project at: https://build.opensuse.org/package/show?package=kamailio&project=home%3Akam… Download links are: http://download.opensuse.org/repositories/home:/kamailio:/telephony/CentOS_… http://download.opensuse.org/repositories/home:/kamailio:/telephony/RedHat_… http://download.opensuse.org/repositories/home:/kamailio:/telephony/Fedora_… http://download.opensuse.org/repositories/home:/kamailio:/telephony/openSUS… The x86_64 build for opensuse is still not completed, some parameter to gcc compiler is not working, should be fixed soon. Note that not all modules are packaged since not all dependencies were met in these distros. The RPM spec was started from what is in source tree as kamailio.spec.CentOS, radically updated for cross compilation. Personally I am not using these distros, therefore it will be appreciated if people using any of them are willing to give an installation test and report if all goes ok. Moreover, I will be very thankful if anyone (can be many) wants to jump in and take over the maintenance of this kamailio build service. It would be good to enable the build for other versions of these distros, probably for many it will just work, if not it will require some adjustments on dependencies. Once these builds prove to be ok and useful, we can move them in the global telephony repository of the opensuse build service. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

Re: [SR-Users] Outbound socket selection (HA implementation)

by Sean O'Donnell

For what it's worth, make sure you have the mhomed patch in forward.c. As I recall, the 3.1.2 source tarball did not contain the fix, but the latest forward.c did. http://www.mail-archive.com/sr-users@lists.sip-router.org/msg03892.html Sean O'Donnell Senior Engineer uReach Technologies, Inc. ---- On Wed, 30 Mar 2011, Bruce McAlister (bruce.mcalister(a)blueface.ie) wrote: All, Thanks for the tips and suggestions, I have now managed to get this working using mhomed=1 and setting $fs, for some reason I could not get "force_send_socket" to work with avp's (but thats a topic for another thread).

Outbound socket selection (HA implementation)

by Asgaroth

Hi All, I'm trying to setup an active/passive proxy instance with kamailio 3.1.2. I'm using ucarp (www.ucarp.org) to provide the floating ip addresses. I have installed and configured ucarp and it appears to be working as expected. I have configured kamailio on both systems to be online all the time (using the net.ipv4.ip_nonlocal_bind kernel parameter on the "standby" server). I have configured kamailio with the listen parameter to be listening on the floating ip addresses only. The problem now is that kamailio uses the inbound interface as the outbound socket for messages (I think this is the default, expected, behaviour). If I enable the "mhomed" parameter then I get the following error: ERROR: <core> [forward.c:218]: ERROR: get_out_socket: no socket found ERROR: <core> [forward.c:572]: forward_req: ERROR: cannot forward to af 2, proto 1 no corresponding listening socket ERROR: sl [sl_funcs.c:282]: ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) I had a look around on the docuwiki and I found $fs. Would I need to force the outbound socket for each message in this case, or do I have a simple comfiguration issue? Any thoughts/comments would be greatly appreciated. Thanks

About tm retrans time on ser or kamailio 3.1?

by Min Wang

HI I did the trace using ngrep: ngrep -T -W byline -d any port 5060 And I am confused with tm retran. (1) case one tm module, the| retr_timer1| default is 500 ms. #U +0.001824 xxx.17:5060 -> xxx.16:5060 INVITE sip:224@172.16.8.49:2057;line=lnzlkxu5 SIP/2.0. #U +0.000012 xxx.17:5060 -> xxx.16:5060 INVITE sip:224@172.16.8.49:2057;line=lnzlkxu5 SIP/2.0. the ngrep show the delta between packet, the second invite is only 12 ms behind? is my understanding correct? (2) change retr_timer1 to 2000 ms modparam("tm", "retr_timer1", 1000) #U +0.001936 xxx.17:5060 -> xxx.16:5060 INVITE sip:224@172.16.8.49:2057;line=lnzlkxu5 SIP/2.0. #U +0.000013 xxx.17:5060 -> xxx.16:5060 INVITE sip:224@172.16.8.49:2057;line=lnzlkxu5 SIP/2.0. the delta still 13 ms behind, so similar to the case 1, The question is: is the second invite the re-trans by tm? If so why it is around 12/13 ms? not the 500 ms or as configured 2000 ms? thanks. Kind regards / Mit freundlichen Grüßen Min Wang

by Daniel-Constantin Mierla

Hello, I thought it is an useful information to announce here that the SIP Communicator SIP softphone was renamed to Jitsi. There are several pages mentioning Kamailio and SIP Communicator out there, among them our participation to Google Summer of Code 2010 as well as the full SIP SIMPLE Presence configuration with XCAP: * http://asipto.com/u/sp To fetch the latest version of this sip softphone you just go to: * http://www.jitsi.org Btw, Kamailio is participating again in GSoC, the 2011 edition, together with Jitsi project -- I will make another message regarding this subject. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com
