download one git branch only

by Daniel-Constantin Mierla

Hello, is anyone aware of a git command that downloads locally only one branch of sip repository? I searched on the web and found only some tools, but maybe there are standard git commands to help. Thanks, Daniel -- Daniel-Constantin Mierla * Kamailio SIP Masterclass, Nov 9-13, 2009, Berlin * http://www.asipto.com/index.php/sip-router-masterclass/

Permission problem and setuid in Kamailio 1.5

by marius zbihlei

Hi all, There is a permission problem if the daemon is started given -u and -g parameters (sets up user and group for the process). The do_suid function (defined in demonize.c) is called after the call to init_modules(), so the mod_init functions of the configured module are loaded before the call to do_suid. This wasn't a problem in 1.3 because no module(I am aware off) use the uid and gid of the process to do permission checks. This has changed in 1.5, module carrierroute, as there is a check to see if the route file in config-file mode (usually /etc/kamailio/carrierroute.conf) has the right permission set on it (Issues an warning if it's worldly writable and error if it's not writable by the process owner). This of course is a problem because kamailio hasn't yet setuid()/setgid() so the checks are done using the wrong uid. A correct (imho) course of action is to move the call to do_suid function before the call to init_modules()(and before any other calls to initialization functions). I've attached a small patch that does this (tested). There are any considerations on why the init_modules() should be called with another uid/gid?

sercmd renaming

by Juha Heinanen

currently i have to make these hacks in order to rename sercmd and DEFAULT_CTL_SOCKET: # Rename sercmd and DEFAULT_CTL_SOCKET sed -i -e 's/NAME=sercmd/NAME=sip-proxy_ctl/' utils/sercmd/Makefile sed -i -e 's!sercmd/sercmd!sercmd/sip-proxy_ctl!' Makefile sed -i -e 's/ser_ctl/sip-proxy_ctl/' modules/ctl/ctl_defaults.h those hack should not be needed and renaming should happen automatically based on MAIN_NAME or SHORT_NAME. i tried once to hack the makefiles for that, but was not successful. -=- juha

[ openser-Bugs-2877313 ] fix_nated_contact() then encode_contact() causes core dump

by SourceForge.net

Bugs item #2877313, was opened at 2009-10-12 21:35 Message generated for change (Tracker Item Submitted) made by You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=743020&aid=2877313&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: modules Group: ver devel Status: Open Resolution: None Priority: 5 Private: No Submitted By: https://www.google.com/accounts () Assigned to: Nobody/Anonymous (nobody) Summary: fix_nated_contact() then encode_contact() causes core dump Initial Comment: When one runs fix_nated_contact() from the nathelper module for it's intended purpose (it must complete successfully) and then run encode_contact() from the siputils module (it also must complete) Kamailio always core-dumps with: CRITICAL:core:del_lump: offset exceeds message size (202688 > 602) aborting... This seems to have something to do with re-writing the contact header twice and not fixing the message size the second time but I can't say for sure. I have a core file, but it seems rather large (44M). It can be uploaded if need be. This is occurring with both the release 1.5.2tls & 1.6.0notls dev trunk. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=743020&aid=2877313&group_…
