setfscreatecon
getfscreatecon(3) SE Linux API documentation getfscreatecon(3)
NAME
getfscreatecon, setfscreatecon - get or set the SE Linux security con-
text used for creating a new file system object.
SYNOPSIS
#include <selinux/selinux.h>
int getfscreatecon(security_context_t *con);
int setfscreatecon(security_context_t context);
DESCRIPTION
getfscreatecon retrieves the context used for creating a new file sys-
tem object. This returned context should be freed with freecon 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, 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.
Note: Signal handlers that perform an setfscreate must take care to
save, reset, and restore the fscreate context to avoid unexpected
behaviors.
RETURN VALUE
On error -1 is returned.
On success getfscreatecon returns the length of the context (not
including the trailing zero byte). On success setfscreatecon returns
0.
