[PATCH 0/4] use standalone libtalloc instead of own copy
by pablo＠gnumonks.org 05 Jul '11

05 Jul '11

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi! With these patches, libosmocore, libosmo-sccp, openbsc and osmo-tetra does not use anymore our own copy of talloc and they rely on the standalone library that is provided by major distributors. The osmocom-bb part is still missing, my idea is to include a copy of libtalloc in the tree in the shared/ directory via rsync. This patch will follow later since we can still rely on the outdated copy of libosmocore. Please, apply.

[PATCH 0/2] libosmocore: logging and signal support for libraries
by pablo＠gnumonks.org 04 Jul '11

04 Jul '11

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi Harald! These are the two patches that I'm using to support signalling and logging in the libraries. The patch that adds the logging support reworks your previous contribution so we only keep the logging subsystem in libosmocore, instead of the full definition of the logging subsystem. See patches descriptions for further details. Let me know if you're OK with these changes.

Question about how to read / send SMS from an external program
by Kang-min Liu 03 Jul '11

03 Jul '11

Hi all, I have been working on a project involved using osmo-nitb and trying to read / send SMS by doing SQL queries directly hlr.sqlite3 in a perl program, but I cannot figure out the encode/decode process on the "user_data" field. From "sms_from_text" function in libmsc/gsm_04_11.c, it appears to me that the content of user_data is a gsm_7bit_encode-ed of text if the SMS is sent with VTY interface. I then tried to port gsm_7bit_decode to perl and the implementation successfully decoded two test strings in libosmocore/tests/sms/sms_test.c. However it does not successfully decode any SMS user_data record in hlr.sqlite3 to the original text. The result looks like just a piece of garbled text, not even close to any human-readable text at all. I also tried briefly to include gsm0338 decoding process, or some other perl-based implementation from CPAN, no success at all. I am currently out of ideas to try. It will be really appreciated if anyone with similar experience can offer insight to my issue here.
