Harald Welte dab0287b3f msgb: fix printing of msgb pointer during MSGB_ABORT() 2010-11-09 13:42:26 +01:00
Harald Welte 46a45a6c4f msgb: don't compare unsigned int with int (fix lcr build) 2010-11-09 13:41:48 +01:00
Harald Welte be6cb17228 msgb_abort(): better formatting 2010-11-05 07:52:22 +01:00
Harald Welte 088e68aff4 generate backtrace in msgb_abort() 
This helps us to debug where we encounter insufficient headroom...
 2010-11-05 07:52:22 +01:00
Harald Welte 929d8870d2 Change msgb_abort() function in MSGB_ABORT argument with variable arguments 
This enables callers to provide format string and arguments to it

Also, put conditionals into the macro, and remove them from the caller
site.

Holger Hans Peter Freyther af270a41e3 gsm0808: Move the clear request from bsc_msc_ip to here 
This method should use the msgb_tlv_put routines instead
of the stuff it is doing. This will be cleaned up.
 2010-11-04 12:42:50 +01:00
Holger Hans Peter Freyther c25c668106 gsm0808: Add a method to create a new DTAP message with a msgb 2010-11-04 12:27:48 +01:00
Holger Hans Peter Freyther a3f05d8609 gsm0808: Add a method to create a clear command message. 
Use the msgb_tv_put functions for putting the data into
the message. Do not support the extended error reports.
 2010-10-27 11:53:23 +02:00
Holger Hans Peter Freyther acffb60c1a msgb: Add non-inlined helper functions to ease with language bindings 
It is easier from languages that dlopen libosmocore to have a function
to access this data than to poke at the bytes of the struct directly. Add
copyright for this method and the reset method I did earlier this year.

Holger Hans Peter Freyther c64970ede5 gsm0480: Add method create own number response 2010-10-18 17:04:49 +02:00
Holger Hans Peter Freyther daa653fc22 ussd: Add a test case, switch parsing to use a gsm48_hdr and len 
The current USSD code is not doing any size checks, add a test
case to find out how easily we access the data out of bounds.
Begin to use the length in some places.
 2010-10-11 09:25:14 +02:00
Holger Hans Peter Freyther 00cb5700e6 gsm0480: Move the USSD parsing code to libosmocore 
- Change u_int8 to uint8
- Change DEBUGP to LOGP
- Change fprintf(stderr, to LOGP(0, LOGL_DEBUG
- We should define log areas used inside libosmocore
 2010-10-09 01:49:11 +08:00
Holger Hans Peter Freyther c87f266522 msgfile: Add a file parser for a simple file format 
This file format will be used to store per country code,
per network code messages. This will be used for various
things ranging from access control, to messages...
 2010-10-08 19:23:18 +08:00
Holger Hans Peter Freyther 55aea5099c gsm0480: Add USSD format functions to libosmocore 
These routines come from OpenBSC, the msgb_wrap_* functions
belong to Mike Haben, the rest is mine. The msgb allocation
is compatible to the GSM48 allocation in OpenBSC.

Harald Welte 6eb7d6c887 [RSL] split rsl_rll_push_l3() L3 LV pushign and rsl_rll_push_hdr()
