getfscreatecon, setfscreatecon - get or set the SELinux security context used
for creating a new file system object
#include <selinux/selinux.h>
int getfscreatecon(char **con);
int getfscreatecon_raw(char **con);
int setfscreatecon(char *context);
int setfscreatecon_raw(char *context);
getfscreatecon() retrieves the context used for creating a new file
system object. This returned context should be freed with
freecon(3) if
non-NULL.
getfscreatecon() sets *con to NULL if no fscreate context has
been explicitly set by the program (i.e. using the default policy behavior).
setfscreatecon() sets the context used for creating a new file system
object. NULL can be passed to
setfscreatecon() to reset to the default
policy behavior. The fscreate context is automatically reset after the next
execve(2), so a program doesn't need to explicitly sanitize it upon
startup.
setfscreatecon() can be applied prior to library functions that
internally perform an file creation, in order to set an file context on the
objects.
getfscreatecon_raw() and
setfscreatecon_raw() behave identically
to their non-raw counterparts but do not perform context translation.
Note: Signal handlers that perform a
setfscreatecon() must take
care to save, reset, and restore the fscreate context to avoid unexpected
behavior.
Note: Contexts are thread specific.
On error -1 is returned. On success 0 is returned.
