/*
Unix socket in ABRT daemon for creating new dump directories.
Why to use socket for creating dump dirs? Security. When a Python
script throwns 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:
-> "NEW"
\0
Providing dump data:
-> "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)
\0
-> "REASON="
string (maximum length 512 bytes)
\0
Finalizing dump creation:
-> "DONE"
\0
