getfscreatecon(3) SELinux API documentation getfscreatecon(3)NAME
getfscreatecon, setfscreatecon - get or set the SELinux security con‐
text used for creating a new file system object
SYNOPSIS
#include <selinux/selinux.h>
int getfscreatecon(security_context_t *con);
int getfscreatecon_raw(security_context_t *con);
int setfscreatecon(security_context_t context);
int setfscreatecon_raw(security_context_t context);
DESCRIPTIONgetfscreatecon() 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 inter‐
nally 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.
RETURN VALUE
On error -1 is returned. On success 0 is returned.
