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 getkeycreatecon_raw(security_context_t *con);
int setkeycreatecon(security_context_t context);
int setkeycreatecon_raw(security_context_t context);
DESCRIPTIONgetkeycreatecon() retrieves the context used for creating a new kernel
keyring. This returned context should be freed with freecon(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 to setkeycreatecon() to reset to the
default policy behavior. The keycreate context is automatically reset
after the next execve(2), so a program doesn't need to explicitly sani‐
tize 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.
getkeycreatecon_raw() and setkeycreatecon_raw() behave identically to
their non-raw counterparts but do not perform context translation.
Note: Signal handlers that perform a setkeycreatecon() 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.
