Pablo Neira Ayuso 14af167a55 osmux: fix buffer management mess in snprintf() calls SNPRINTF_BUFFER_SIZE() looks too complex, previous version maintains two different variables to account for the remaining space in the buffer, one of them is always decremented based on what snprintf() returns, which may result in underflow. These variables are swapped - not used consistently - all over this code. Replace this macro by a simplified version, with one single parameter to account for remaining space. This macro also deals with two corner cases: 1) snprintf() fails, actually never happens in practise, but documentation indicates it may return -1, so let's catch this case from here to stick to specs. 2) There is not enough space in the buffer, in that case, keep increasing offset, so we know how much would have been printed, just like snprintf() does. Thanks to Pau Espin for reporting, and Holger for clues on this. I have run osmux_test and, at quick glance, it looks good.

libosmo-netif- Osmocom network interface interface library

This repository contains a C-language library that form the basis of various higher-layer cellular communications protocol implementation. It implements stream server and clients for TCP, UDP, IPA as well as the non-standard/proprietary OSMUX protocol.

Homepage

The official homepage of the project is https://osmocom.org/projects/libosmo-netif

GIT Repository

You can clone from the official libosmo-netif.git repository using

git clone git://git.osmocom.org/libosmo-netif.git

There is a cgit interface at http://git.osmocom.org/libosmo-netif/

Documentation

There is no Doxygen-generated API documentation yet for this library. It would be great to some day have it, comparable to libosmocore.
