[PATCH 0/6] gtp: misc improvements
by Andreas Schultz 30 Jan '17

30 Jan '17

Hi Pablo, This series lays the groundwork for removing the socket references from the GTP netdevice by removing duplicate code and simplifying the logic on some code paths. It slighly changes the GTP genl API by making the socket parameters optional (though one of them is still required). The removal of the socket references will break the 1:1 releation between GTP netdevice and GTP socket that prevents us to support multiple VRFs with overlaping IP addresse spaces attached to the same GTP socket (needed for multi APN support). Regards Andreas -- Andreas Schultz (6): gtp: make GTP sockets in gtp_newlink optional gtp: merge gtp_get_net and gtp_genl_find_dev gtp: unify genl_find_pdp and prepare for per socket lookup gtp: consolidate pdp context destruction into helper gtp: add socket to pdp context gtp: consolidate gtp socket rx path drivers/net/gtp.c | 564 +++++++++++++++++++++++++++--------------------------- 1 file changed, 280 insertions(+), 284 deletions(-) -- 2.10.2

[PATCH net v3 0/3] various gtp fixes
by Andreas Schultz 27 Jan '17

I'm sorry for the compile error mess up in the last version. It's no excuse for not test compiling, but the hunks got lost in a rebase. This is the part of the previous "simple gtp improvements" series that Pablo indicated should go into net. The addition of the module alias fixes genl family autoloading, clearing the DF bit fixes a protocol violation in regard to the specification and the netns comparison fixes a corner case of cross netns recv.

HEADS UP: jenkins DOWN
by Neels Hofmeyr 27 Jan '17

27 Jan '17

While I was waiting for jenkins just now, I noticed that it was getting impossibly slow despite an idle CPU. An attempt to restart resulted in failure to launch jenkins due to "Disk quota exceeded". There are things happening that I don't understand (file system is shrinking as I remove files). I need help from Holger (or Harald?), to understand and probably fix with a simple command making more space for the jail... Until then our jenkins will be DOWN :/ ~N -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

test error analysis on build services
by Neels Hofmeyr 26 Jan '17

26 Jan '17

On jenkins and opensuse, we have builds where we cannot easily analyse the testsuite.dir after a build failed. So we only see which tests failed and not why. On jenkins I have in most places added a script invocation that prints all testsuite.dir/*/*.log in case of build failure, so we can see it in the jenkins log right away. On opensuse.org, IIUC, the 'make check' is run by dh or something, so it's not trivial (to me) to make it output the test logs in case of failure. I'm thinking now, don't we always want to see these failures anyway? We could include in our Makefile.am a tweak to print the test logs in case of testsuite failure. Sometimes this output can become fairly large though; e.g. when a long test fails early and prints "nothing", the test log shows a huge diff with all expected output as minus-lines. My main goal right now is to see why/how the libosmo-netif OBS build failed (osmux test fails) without further local reproduction effort. This situation will certainly repeat over and over, for all of the other projects as well. What do you think? Can we get that easily? ~N -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

jenkins nr of executors
by Neels Hofmeyr 26 Jan '17

26 Jan '17

FYI, no "Broken Pipe" errors in a long time, so today I increased the OsmocomBuild1 nr of executors from 3 to 4 ... and immediately got two subsequent openbsc builds hitting the "Broken Pipe" again. https://jenkins.osmocom.org/jenkins/job/OpenBSC-gerrit/1716/IU=--enable-iu,… https://jenkins.osmocom.org/jenkins/job/OpenBSC-gerrit/1717/IU=--disable-iu… This time I tried something else: lower the "make -j 9" to "make -j 3" and leave the nr of executors at 4... Just dabbling, would be nicer to pinpoint the real cause. ~N -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

[PATCH 0/5] simple gtp improvements
by Andreas Schultz 25 Jan '17

25 Jan '17

As requested are here the simple and most obvious changes from the larger GTP changeset. I'll break down the rest and send them out separately. The module alias addition and the rcu_lock removal are just small convenience changes. The other changes are needed to correctly implement one of the 3GPP GW functions, userspace needs to see invalid T-PDU's in order to generate the proper error messages, GTP fragmentation rules need the cleared DF bit.
