OpenBSC / lcr integration through unix domain socket
by Harald Welte 23 Dec '10

23 Dec '10

Hi! I've finally taken up the taks to split the 'siamese twin' of linking lcr with bsc_hack and replace it with a PF_UNIX, SOCK_SEQPACKET socket. I've done quite a bit of testing and it seems to work fine. The bsc_hack side is complete, i.e. it properly handles the loss of the lcr connection and drops all CC transactions at that point. The lcr side is less finished, especially * it will not drop all calls when the OpenBSC [socket] goes away * it will not re-connect if OpenBSC has disappeared I hope those can still be adressed properly ahead of 27C3. Andreas: Not sure if you have some time to look at it. I'll be working on higher priority items for the 27C3 deployment tomorrow... The openbsc code is in the laforge/mncc_sock branch of openbsc.git The lcr code can be found in the mncc_sockk branch of the unofficial lcr.git repo at git://git.osmocom.org/lcr.git Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

> newbie question: what does this dmesg mean? hi thomas, this happens, if the user space process does not read from the b-channel socket. since the b-channels have no flow control, the packets get dropped and an error message is printed by the kernel. what program do you use? andreas
