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