Vadim Yanitskiy 9c603e64bf logging: fix NULL pointer dereference in _output_buf()
In the _output_buf() we explicitly initialize only the 'buf' and 'len'
fields of the struct osmo_strbuf, leaving the 'pos' field implicitly
initialized to NULL.  Later, in this function, 'sb.pos' is passed to
ctime_r() and strlen(), leading to a NULL pointer dereference (segfault)
in certain scenarios.

This situation can occur when color logging is disabled or when
a specific logging subsystem has no associated color.  Any application
using libosmocore's logging API would crash with the following config:

log stderr
 logging filter all 1
 logging timestamp 1
 logging color 0

Fix this by initializing the 'pos' field explicitly.

Fixes: d71331bc "logging: fix nul octets in log output / use osmo_strbuf"

README.md

libosmocore - set of Osmocom core libraries

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.

The libosmocore.git repository build multiple libraries:

  • libosmocore contains some general-purpose functions like select-loop abstraction, message buffers, timers, linked lists
  • libosmovty contains routines related to the interactive command-line interface called VTY
  • libosmogsm contains definitions and helper code related to GSM protocols
  • libosmoctrl contains a shared implementation of the Osmocom control interface
  • libosmogb contains an implementation of the Gb interface with its NS/BSSGP protocols
  • libosmocodec contains an implementation of GSM voice codecs
  • libosmocoding contains an implementation of GSM channel coding
  • libosmosim contains infrastructure to interface SIM/UICC/USIM cards
