getsockcreatecon(3) SELinux API documentation getsockcreatecon(3)
getsockcreatecon, setsockcreatecon - get or set the SELinux security
context used for creating a new labeled sockets
#include <selinux/selinux.h>
int getsockcreatecon(char **con);
int getsockcreatecon_raw(char **con);
int setsockcreatecon(char *context);
int setsockcreatecon_raw(char *context);
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
explicitly 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
unexpected behavior.
Note: Contexts are thread specific.
On error -1 is returned. On success 0 is returned.
