frame_eval()

static unlang_frame_action_t frame_eval ( request_t *  request, unlang_stack_frame_t *  frame  )

inlinestatic

Evaluates all the unlang nodes in a section.

This function interprets a list of unlang instructions at a given level using the same stack frame, and pushes additional frames onto the stack as needed.

This function can be seen as moving horizontally.

Parameters

[in]	request	The current request.
[in]	frame	The current stack frame.

Returns

• UNLANG_FRAME_ACTION_NEXT evaluate more instructions in the current stack frame which may not be the same frame as when this function was called.
• UNLANG_FRAME_ACTION_POP the final result has been calculated for this frame.

result_calculate()

static unlang_frame_action_t result_calculate ( request_t *  request, unlang_stack_frame_t *  frame, unlang_result_t *  result  )

inlinestatic

Update the current result after each instruction, and after popping each stack frame.

Note

Sets stack->scratch to be the the result of the frame being popped.

Parameters

[in]

request

The current request.

Returns

• UNLANG_FRAME_ACTION_NEXT evaluate more instructions.
• UNLANG_FRAME_ACTION_POP the final result has been calculated for this frame.

result_pop()

static unlang_frame_action_t result_pop ( request_t *  request, unlang_stack_frame_t *  frame, unlang_result_t *  result  )

inlinestatic

Function called to merge inter-stack-frame results.

This function is called whenever a frame is popped from the stack.

'result' is the result from the frame being popped, and 'frame' is the next highest frame in the stack.

The logic here is very similar to result_eval(), with two important differences:

• The priority of the lower frame is ignored, and the default priority of the higher frame is used. Unless the higher frame's priority is MOD_ACTION_NOT_SET, in which case the lower frame's priority is used.

unlang_interpret()

rlm_rcode_t unlang_interpret	(	request_t *	request,

	)

Run the interpreter for a current request.

This function runs the interpreter for a request. It deals with popping stack frames, and calaculating the final result for the frame.

Parameters

[in]	running	Is the interpreter already running.

Returns

The final request rcode.

	)

Initialize a unlang compiler / interpret.

Parameters

unlang_interpret_signal()

void unlang_interpret_signal	(	request_t *	request,

This does NOT immediately stop the request, it just deliveres signals, and in the case of a cancel, marks up frames for unwinding and adds it to the runnable queue if it's yielded.

This function should be safe to call anywhere.

Here is the caller graph for this function:

unlang_stack_signal()

void unlang_stack_signal	(	request_t *	request,
		fr_signal_t	action,
		int	limit
	)

Delivers a frame to one or more frames in the stack.

This is typically called via an "async" action, i.e. an action outside of the normal processing of the request.

For FR_SIGNAL_CANCEL all frames are marked up for cancellation, but the cancellation is handled by the interpret.

Other signal types are delivered immediately, inrrespecitve of whether the request is currently being processed or not.

Signaling stops at the "limit" frame. This is so that keywords such as "timeout" and "limit" can signal frames lower than theirs to stop, but then continue with their own work.

Note

It's better (clearer) to use one of the unwind_* functions unless the entire request is being cancelled.

Parameters

[in]	request	The current request.
[in]	action	to signal.
[in]	limit	the frame at which to stop signaling.
