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);
DESCRIPTIONgetkeycreatecon 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 doesn't 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.
