[systemd-devel] [PATCH] ask-password: prevent buffer overrow when reading from keyring

When we read from keyring, a temporary buffer is allocated in order to determine the size needed for the entire data. However, when zeroing that area, we use the data size returned by the read instead of the lesser size allocate for the buffer. That will cause memory corruption that causes

[systemd-devel] sd-bus dynamic property table

I have a simple application that does provides property table for network devices (maybe it would be useful for a more complete example somewhere). The app is more to show how to use sdbus, not to replace network manager. The next step is to add ethtool statistics. Each type of network device
