[Libguestfs] [Bug 1406906] [PATCH 0/3] Fix segmentation fault in Python bindings

This series addresses the issue where non UTF8 file names in a guest image lead to libguestfs segfault with Python 3 APIs. The core issue is the APIs are not checking the return value when constructing a new PyObject. Therefore NULL pointers are added to Python collections (lists and dictionaries) crashing the application. Few notes regarding the comments on the previous patch. - Added a regression test file - Removed the Exception string setter functions as Python APIs already set them in case of error https://docs.python.org/3.6/c-api/exceptions.html#exception-handling (third paragraph) - Fixed functions in python/handle.c - Correctly clear and decrement the refcount of the list/dictionary object before returning on error Matteo Cafasso (3): generator: check return value of Python object functions python: check return value of object functions in handle.c python: add regression test for RHBZ#1406906 generator/python.ml | 119 +++++++++++++++++++++++++---------------- python/handle.c | 48 +++++++++++++---- python/t/test830RHBZ1406906.py | 55 +++++++++++++++++++ 3 files changed, 165 insertions(+), 57 deletions(-) create mode 100644 python/t/test830RHBZ1406906.py -- 2.11.0
