getsockcreatecon(3) SELinux API documentation getsockcreatecon(3)

NAME getsockcreatecon, setsockcreatecon - get or set the SELinux security context used for creating a new labeled sockets.

SYNOPSIS #include <selinux/selinux.h>

int getsockcreatecon(security_context_t *con);

int setsockcreatecon(security_context_t context);

DESCRIPTION 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 behavior).

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 objects.

Note: Signal handlers that perform an setsockcreate must take care to save, reset, and restore the sockcreate context to avoid unexpected behavior.

RETURN VALUE On error -1 is returned. On success 0 is returned.
