-Unix socket in ABRT daemon for creating new dump directories.
-
-Why to use socket for creating dump dirs? Security. When a Python
-script throws unexpected exception, ABRT handler catches it, running
-as a part of that broken Python application. The application is running
-with certain SELinux privileges, for example it can not execute other
-programs, or to create files in /var/cache or anything else required
-to properly fill a dump directory. Adding these privileges to every
-application would weaken the security.
-The most suitable solution is for the Python application
-to open a socket where ABRT daemon is listening, write all relevant
-data to that socket, and close it. ABRT daemon handles the rest.
-
-** Protocol
-
-Initializing new dump:
-open /var/run/abrt.socket
-
-Providing dump data (hook writes to the socket):
--> "PID="
-   number 0 - PID_MAX (/proc/sys/kernel/pid_max)
-   \0
--> "EXECUTABLE="
-   string (maximum length ~MAX_PATH)
-   \0
--> "BACKTRACE="
-   string (maximum length 1 MB)
-   \0
--> "ANALYZER="
-   string (maximum length 100 bytes)
-   \0
--> "BASENAME="
-   string (maximum length 100 bytes, no slashes)
-   \0
--> "REASON="
-   string (maximum length 512 bytes)
-   \0
-
-Finalizing dump creation:
--> "DONE"
-   \0
