This slightly modified networkmanager ebuild will support a new useflag to enable modemmanager for making connections via USB-based modem devices. This made my HDSPA USB device work properly with NM. I hope to get some feedback and testing.
Created attachment 180954 [details] modified NM ebuild This ebuild has a new useflag to enable or disable the modemmanager stuff. When enabled it will patch the original sources and pull in modemmanager as a dep.
Created attachment 180955 [details, diff] patch for NM sources
Created attachment 180956 [details] git version of modemmanager needed primarily for debugging, but will also install some dbus configuration
Hi Christian, Thank you for your patch. As you probably saw, we were considering adding modemmanager support in the past (pre-0.7) in the overlay. Because modemmanager is still a moving target (no official release yet) and because networkmanger doesn't have direct support (without patching) we postponed it. I will have a chat with modemmanager maintainer and ask about NM integration.
If you mean Tambet with developer, I talked to him on IRC today. He plans to merge the MM stuff into NM trunk soon. But even then it will take some time till it gets released, IMHO. That's why I decided to make my work of today available here.
Yeah, I meant Tambet. I dropped him an email just a few minutes ago. Once modemmanager gets merged to the trunk, I will backport the changes to current NM. Hopefully 0.7.1 should also be available soon. Rob

After that he will push some patches to NM for proper integration. Once it's in NM git tree - I will backport it. Rob
Just a quick update. It seems Tambet released ModemManager-0.2 today and pushed necessary patches to the tree. You will find updated ebuild in rbu's overlay tomorrow. Rob
As promised networkmanger-0.7.0-r2 is now available in rbu's overlay (with modemmanager-0.2). This version has some patches backported from trunk and well as modemmanger support (via modemmanager use flag). This package needs some testing as I didn't have enough time to extensively test it myself. Please test it and report the results. Rob
Just gave it a try on my PPC machine. It works great now and makes a mobile connection that just works. Thanks for the backporting.
Hmm, too early to tell if it works: I am just noticing that I suddenly have a modemmanager process running, eating all my CPU time. It started roughly about 5-10 minutes after disconnecting my test connection. Can anyone reproduce it?

After running NM for around 10 min: $ ps ax | grep Network 5475 ? S 0:01 /usr/sbin/nm-system-settings --config /etc/NetworkManager/nm-system-settings.conf 8869 ? Ssl 0:00 /usr/sbin/NetworkManager --pid-file /var/run/NetworkManager.pid $ ps ax | grep modem 8880 ? S 0:00 /usr/sbin/modem-manager I can't see it on top/powertop/iotop. It's almost invisible (only ps ax | grep shows it's there). I tested with Huawei E169 and it seems ok.
Still debugging the issue, but I found another bug: modemmanager does not compile with stable glib. I had to keyword it unstable to make it work.
...and here is a patch that should solve the CPU issue: http://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=13facad4fa3be24d07768892135caebd88e95fcc

If it doesn't compile fine with glib 2.16.6 (last mark stable in gentoo), than that's a bug in modemmanager.
Sorry, I was not able to test it until now since I had problems with the applet. Now it's working again and I can confirm that the patch solves the problem.

Thanks for testing. Patch backported in rbu's overlay. When it comes to glib, I couldn't test it myself. It seems downgrading glib is the best way to mess up your system (after downgrade revdep-rebuild wanted to reinstall half of my system: Total: 149 packages (2 upgrades, 147 rebuilds), 126.31 MBytes to download )
Ok, I also found the problem that leads to the compile error with glib-2.16. It is a missing #include <signal.h> in main.c of MM. See this commit here: http://cgit.freedesktop.org/ModemManager/ModemManager/diff/src/main.c?id=bef9c48ffc926b97a7c0b1d56b9de751e37efe69
I've start shipping NM-0.8_pre version, which include modemmanager support. Backporting current code to work with 0.7.x was a way too much overhead.
