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 network 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 san-
itize it upon startup.
setsockcreatecon can be applied prior to library functions that internally 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.
