Detailed Description

Implementation of functions to interact with the security context.

Todo:

Enable checking (not just using a stub returning True.)

Complete implementation for BCB acceptor.

Function Documentation

BSL_SecCtx_ExecutePolicyActionSet()

int BSL_SecCtx_ExecutePolicyActionSet	(	BSL_LibCtx_t *	lib,
		BSL_SecurityResponseSet_t *	output_response,
		BSL_BundleRef_t *	bundle,
		const BSL_SecurityActionSet_t *	action_set
	)

Call the underlying security context to perform the given action.

Parameters

[in]	lib	This BSL context
[out]	output_response	Pointer to allocated, zeroed memory into which the response is populated
[in,out]	bundle	Pointer to bundle, which may be modified.
[in]	action_set	Action containing all params and operations.

Returns

0 on success, negative on failure.

Notes:

• It should evaluate every security operation, even if earlier ones failed.
• The outcome can indicate in the policy action response how exactly it fared (pass, fail, etc)
• BCB will be a special case, since it actively manipulates the BTSD
