Holger Hans Peter Freyther f632371b76 ussd: Verify that parsing is stil working and print the decoded text. 2010-10-11 09:26:19 +02:00
Holger Hans Peter Freyther c88a44f493 ussd: Add next test that show that we access the data out of bounds 
This test is showing that the internal ASN1 code is not checking
the size properly.

Holger Hans Peter Freyther 8ac0486c28 ussd: Check the structure of the IE. 
This is fixing the current crashes. Next we will need to
manipulate the content...

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.

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

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...

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.

Sylvain Munaut 47ee693170 gsm48: Fix gsm48_encode_called - Set no extension bit 
The highest bit must be set as "No extension byte" marker,
so that the next byte is considered to be the BCD number
and not some more control stuff

Holger Hans Peter Freyther a55caad039 gsm0808: Fix the TLV definition of CIC and Service Handover 
The nat code stumbled over the CIC bug as it was detecting
timeslot 0x1 as a new CIC and we were patching the data outside
the actual packet... The TLV parser needs some better size
checking too.

Holger Hans Peter Freyther 08aaded3b8 vty: Add functions to access index and node 
It is easier to call these two functions from bindings than
wrapping the vty structure and figuring out the alignment of
the enum on all different ABIs.

Holger Hans Peter Freyther e25b18aa29 vty: Link osmovty to osmocore as it is using the symbols 
Use SUBDIRS to build src first and the src/vty. We will need
to find the right way add the dependencies.

Holger Hans Peter Freyther 8304b1e3e9 vty: Everything <= CONFIG_NODE is not a child of config 
The method should be renamed to is child of config node
as it was comparing if vty->node > CONFIG_NODE. This is
fixing an assert in go_to_parent as we tried to find a
parent for the CONFIG_NODE.

Holger Hans Peter Freyther 50cfb780d2 vty: Move the assumption of the config nodes into a function 
Move the assumption that something is a child of the CONFIG_NODE
into a new function. The next step will be to use something else
for that.

code will workaround the issue and provide a way to set a breakpoint
at the right position in the code.

Holger Hans Peter Freyther f8a342c350 gsm_7bit_decode: rtext does not hold a null byte, reduce the size 
I have added the + 1 as I thought rtext will hold a terminating
null byte but it will not.

Nico Golde c0ce9aa20d tests: don't hardcode length values of expected encoding gsm_7bit_encode: 
make sure to return the number of actually written bytes gsm_7bit_decode:
calculate length of resulting septets from input length before decoding

The input length to gsm_7bit_decode reflects the number of encoded bytes
to be decoded. As the decoding is done on the input in septetes we need
to take this into account and recalculate the length.

Holger Hans Peter Freyther 446bf37698 gsm_7bit_decode: Handle the case of the last charachter being an escape 
If i + 1 == length and it is an escape charachter we would try
to read rtext[length] which is one after the field we have allocated.
