[SR-Users] 5.0 to 5.1 - No module matching <geoip2> found

After a clean system install (CentOS 7) -

Using default 5.1 cfg file this time for testing with these added lines (in proper locations):

loadmodule "geoip2.so"

modparam("geoip2", "path", "/usr/local/share/GeoIP/GeoLite2-City.mmdb")

if (geoip2_match("$si", "src")) {
                }

Again, I have working fine on another host, that does have a different kernel version / other packages.
Any ideas?

I noticed that there were SE contexts applied to pretty much all folders, /usr/bin/lib (where my libmaxminddb lives)  /usr/local/sbin and even /usr/local/src/.

The security context applied was: unconfined_u:object_r:usr_t:s0

I haven’t figured out what caused this, as I have systems without this behavior. My guess is it is related to disabling selinux after the build was complete. Despite my efforts resetting SE linux and removing contexts from affected files the problem persists. I’ve removed all install and src files, built again and the same problem persisted.

As far as the script errors, there are none. The cfg file is in active operation on other hosts. If I leave the IFDEF/ENDIF statements active and comment out only the statements related to geoip Kamailio starts fine.

A system rebuild will fix but I thought this behavior was odd and there could be a way to fix.

Hello,

On 15.12.17 05:12, Daniel W. Graham wrote:
Its installed and was working prior to the 5.1 upgrade.

I got the module error fixed. For whatever reason there was an SE context applied to the libmaxminddb.* files that was killing permissions. I was able to reset them. SE linux was disabled prior and is currently.
interesting and good to know that SE linux behaves like this ... could you find a reason for this restriction by SE linux, like the file being in a specific folder?


I still get -

Can you check the blocks IFDEF/ENDIF to be sure you have matching pairs?

Cheers,
Daniel

You need to have libmaxminddb library installed.

What OS are you using?

If deb based:

$ dpkg -l | grep maxmind

If rpm based:

$ rpm -qa | grep maxmind


Cheers,
Joel.

Upgraded two installs to 5.1.

If I copy cfg file from install 2 to install 1, no issues with install 1.

Any idea what could be going wrong?
