getkeycreatecon(3) SELinux API documentation getkeycreatecon(3)

NAME getkeycreatecon, setkeycreatecon - get or set the SELinux security con- text used for creating a new kernel keyrings.

SYNOPSIS #include <selinux/selinux.h>

int getkeycreatecon(security_context_t *con);

int setkeycreatecon(security_context_t context);

DESCRIPTION getkeycreatecon retrieves the context used for creating a new kernel keyring. This returned context should be freed with freecon 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 to setkeycreatecon to reset to the default policy behavior. The keycreate context is automatically reset after the next execve, so a program doesnt need to explicitly sanitize it upon startup.

setkeycreatecon 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 setkeycreate must take care to save, reset, and restore the keycreate context to avoid unexpected behavior.

RETURN VALUE On error -1 is returned. On success 0 is returned.
