getsockcreatecon retrieves the context used for creating a new labeled
network socket. This returned context should be freed with freecon if
non-NULL. getsockcreatecon sets *con to NULL if no sockcreate context
has been explicitly set by the program (i.e. using the default policy
setsockcreatecon sets the context used for creating a new labeled net-
work sockets NULL can be passed to setsockcreatecon to reset to the
default policy behavior. The sockcreate context is automatically reset
after the next execve, so a program doesn't need to explicitly sanitize
it upon startup.
setsockcreatecon can be applied prior to library functions that inter-
nally perform an file creation, in order to set an file context on the

save, reset, and restore the sockcreate context to avoid unexpected
