Once check_level has identified the first target that might have an output osmo_vlogp will continue from this place. In practice we have one (stderr/syslog) or two (stderr+VTY) log outputs so avoiding to re-iterate is not that important but as we have found the right place we can just use it. http://cgit.osmocom.org/libosmocore/commit/?id=87215d5bd97b0ba9249825dcbfb4… commit 87215d5bd97b0ba9249825dcbfb4d449f42b5a15 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Mon Dec 21 14:45:16 2015 +0100 logging: Remove some code duplication Extract the mapping of the subsystem number and the checking for the loglevel to a inline method that is shared between the new and old. http://cgit.osmocom.org/libosmocore/commit/?id=f96826f2039a4a794f86ea3d81d3… commit f96826f2039a4a794f86ea3d81d3a728a6450847 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Nov 17 11:52:26 2015 +0100 log/test: Extend test case for log_check_level This commit adds OSMO_ASSERTs for mandatory conditions related to log_check_level, and fprintfs for optional conditions, since it is always safe for log_check_level to return != 0. Sponsored-by: On-Waves ehf http://cgit.osmocom.org/libosmocore/commit/?id=67c96eb2babc9eed8a4a6d3c98ad… commit 67c96eb2babc9eed8a4a6d3c98ad52eb9ad63877 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Nov 17 11:52:25 2015 +0100 log: Add conditional logging based on log_check_level Currently the LOGP/DEBUGP arguments are always evaluated even if no logging will happen at all. This can be expensive, for instance if hexdumps or pretty printed object names are generated. This causes high base load especially on embedded devices and is a major part of CPU usage e.g. of the osmo-pcu. This commit uses the log_check_level function to avoid the evaluation of the parameters if it is known in advance, that no logging entry will be generated. Sponsored-by: On-Waves ehf http://cgit.osmocom.org/libosmocore/commit/?id=5fcc4f6ff75a3b3e2027ceceb6bc… commit 5fcc4f6ff75a3b3e2027ceceb6bcdaac6c9c0ba2 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Nov 17 11:52:24 2015 +0100 log: Add log_check_level function This commit adds this predicate function which can be used to avoid the execution of code if a certain log level is not enabled. The function will only return 0 (false), if it is sure that a logging call for the same facility and level will not produce any output. This safety criterion shall ensure, that no logging output is lost due to the use of this predicate as a guard. On the other hand, even if the predicate returns != 0 (true), no logging output might get generated by a similar logging command. Note that the current implementation is not focussed on performance, which could be improved by using a lookup table instead of iterating through every target.

You have to specify the real downlink device that will be used to tunnel traffic, eg. -g=eth0 This means that the gtp0 device will be created and it will use eth0 as the real device to encapsulate packet coming from the Internet that are addressed to the MS (so the tunnel devuce encapsulates these IP packets in GTP packets when traveling to the SGSN). Alternatively, you can also add this to the ggsn.conf configuration file: gtpnl eth0 The device has to be the real device that can route packets to the SGSN, if you select the wrong device, the kernel routing code may not find a way to reach the SSGN, you've been warned. Therefore, if this option is set, the operational becomes the following: 1) A gtp0 device is created via rtnetlink and configure the socket encapsulation infrastructure in the kernel. 2) Whenever a PDP context is created, this adds the necessary tunnel configuration via genetlink GTP interface. 3) Whenever a PDP context is destroyed, this deletes the tunnel via genetlink GTP interface. 4) Destroy the gtp0 device if ggsn is stopped, including all of the existing tunnels. You require the osmo-ggsn.git tree, which contains the kernel module gtp.ko and the libgtpnl library that you have to compile and install. Make sure you have loaded the gtp.ko kernel module before launching the ggsn daemon using the kernel driver mode, otherwise you will get a nice "operation not supported" error message ;-). This patch also adds supports for "ipup" configuration option to invoke an external script after the gtp0 device has been brought up. Typical command to add the route to reach the MS behind the GGSN is required, eg. ip route add 10.0.0.0/8 dev gtp0. The (horrible) ggsn parser has been manually extended to support the new configuration option. That code doesn't look nice, but it just mimics what we already have there for consistency, please don't blame me for that. If you want to run in debugging mode, I suggest you to use: sudo ggsn -c ggsn.conf -f -d Note that you do have to run openggsn as root to bring up the gtp0 device. You have to see this message that announce that the GTP kernel mode is enabled. openggsn[1106]: ggsn.c: 656: Using the GTP kernel mode (genl ID is 25) This patch also automagically sets up route to reach MS from Internet just like tun mode does. This is fundamental to get this working, better don't leave to the admin, he may forget to add this route. In this patch, I tried to encapsulate this new feature as much as possible as Harald initially suggested. To compile this feature, you have to pass --enable-gtp-kernel, ie. ./configire --enable-gtp-kernel Otherwise, the code to interact with the gtp kernel part is not compiled.
