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(char **con);
int getsockcreatecon_raw(char **con);
int setsockcreatecon(char *context);
int setsockcreatecon_raw(char *context);
DESCRIPTION
getsockcreatecon() retrieves the context used for creating a new la-
beled 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 explicitly
sanitize it upon startup.
setsockcreatecon() can be applied prior to library functions that in-
ternally 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 unexpected
behavior.
Note: Contexts are thread specific.
RETURN VALUE
On error -1 is returned. On success 0 is returned.
