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 getsockcreatecon_raw(security_context_t *con);
int setsockcreatecon(security_context_t context);
int setsockcreatecon_raw(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(3) 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(2), so a program doesn't need to explic-
itly sanitize 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.
getsockcreatecon_raw() and setsockcreatecon_raw() behave identically to their non-raw counterparts but do not perform context translation.
Note: Signal handlers that perform a setsockcreatecon() must take care to save, reset, and restore the sockcreate context to avoid unex-
pected behavior.
Note: Contexts are thread specific.
RETURN VALUE
On error -1 is returned. On success 0 is returned.
