.SH "DESCRIPTION"
|
||
|
|
.BR getkeycreatecon ()
|
||
|
|
retrieves the context used for creating a new kernel keyring.
|
||
|
|
This returned context should be freed with
|
||
|
|
.BR freecon (3)
|
||
|
|
if non-NULL.
|
||
|
|
.BR getkeycreatecon ()
|
||
|
|
sets *con to NULL if no keycreate context has been explicitly
|
||
|
|
set by the program (i.e. using the default policy behavior).
|
||
|
|
|
||
|
|
.BR setkeycreatecon ()
|
||
|
|
sets the context used for creating a new kernel keyring.
|
||
|
|
NULL can be passed to
|
||
|
|
.BR setkeycreatecon ()
|
||
|
|
to reset to the default policy behavior.
|
||
|
|
The keycreate context is automatically reset after the next
|
||
|
|
.BR execve (2),
|
||
|
|
so a program doesn't need to explicitly sanitize it upon startup.
|
||
|
|
|
||
|
|
.BR setkeycreatecon ()
|
||
|
|
can be applied prior to library
|
||
|
|
functions that internally perform an file creation,
|
||
|
|
in order to set an file context on the objects.
|
||
|
|
|
||
|
|
.BR getkeycreatecon_raw ()
|
||
|
|
and
|
||
|
|
.BR setkeycreatecon_raw ()
|
||
|
|
behave identically to their non-raw counterparts but do not perform context
|
||
|
|
translation.
|
||
|
|
|
||
|
|
.B Note:
|
||
|
|
Signal handlers that perform a
|
||
|
|
.BR setkeycreatecon ()
|
||
|
|
must take care to
|
||
|
|
save, reset, and restore the keycreate context to avoid unexpected behavior.
