63 *
64 * The platform lacks support for double-width integer division (64-bit
65 * division on a 32-bit platform, 128-bit division on a 64-bit platform).
66 *
67 * Used in:
68 * include/mbedtls/bignum.h
69 * library/bignum.c
70 *
71 * The bignum code uses double-width division to speed up some operations.
72 * Double-width division is often implemented in software that needs to
73 * be linked with the program. The presence of a double-width integer
74 * type is usually detected automatically through preprocessor macros,
75 * but the automatic detection cannot know whether the code needs to
76 * and can be linked with an implementation of division for that type.
77 * By default division is assumed to be usable if the type is present.
78 * Uncomment this option to prevent the use of double-width division.
79 *
80 * Note that division for the native integer type is always required.
81 * Furthermore, a 64-bit type is always required even on a 32-bit
Andres Amaya Garcia2801d002017-07-21 10:56:22 +010082 * platform, but it need not support multiplication or division. In some
83 * cases it is also desirable to disable some double-width operations. For
84 * example, if double-width division is implemented in software, disabling
85 * it can reduce code size in some embedded targets.

92 * The platform lacks support for 32x32 -> 64-bit multiplication.
93 *
94 * Used in:
95 * library/poly1305.c
96 *
97 * Some parts of the library may use multiplication of two unsigned 32-bit

99 * platforms, this is not available in hardware and has to be implemented in
100 * software, usually in a library provided by the toolchain.
101 *
102 * Sometimes it is not desirable to have to link to that library. This option
103 * removes the dependency of that library on platforms that lack a hardware
104 * 64-bit multiplier by embedding a software implementation in Mbed TLS.
105 *
106 * Note that depending on the compiler, this may decrease performance compared
107 * to using the library function provided by the toolchain.

275 * For example, when a function accepts as input a pointer to a buffer that may
276 * contain untrusted data, and its documentation mentions that this pointer
277 * must not be NULL:
Gilles Peskinec7ad1222019-06-13 16:44:19 +0200278 * - The pointer is checked to be non-NULL only if this option is enabled.
279 * - The content of the buffer is always validated.
Andrzej Kurekc470b6b2019-01-31 08:20:20 -0500280 *
281 * When this flag is defined, if a library function receives a parameter that
Gilles Peskinec7ad1222019-06-13 16:44:19 +0200282 * is invalid:
283 * 1. The function will invoke the macro MBEDTLS_PARAM_FAILED().
284 * 2. If MBEDTLS_PARAM_FAILED() did not terminate the program, the function
285 * will immediately return. If the function returns an Mbed TLS error code,
286 * the error code in this case is MBEDTLS_ERR_xxx_BAD_INPUT_DATA.
Andrzej Kurekc470b6b2019-01-31 08:20:20 -0500287 *
Gilles Peskinec7ad1222019-06-13 16:44:19 +0200288 * When defining this flag, you also need to arrange a definition for
289 * MBEDTLS_PARAM_FAILED(). You can do this by any of the following methods:
290 * - By default, the library defines MBEDTLS_PARAM_FAILED() to call a
291 * function mbedtls_param_failed(), but the library does not define this
292 * function. If you do not make any other arrangements, you must provide
293 * the function mbedtls_param_failed() in your application.
294 * See `platform_util.h` for its prototype.
295 * - If you enable the macro #MBEDTLS_CHECK_PARAMS_ASSERT, then the
Jaeden Amerodbe4ff82019-07-04 21:15:37 +0100296 * library defines MBEDTLS_PARAM_FAILED(\c cond) to be `assert(cond)`.
Gilles Peskinec7ad1222019-06-13 16:44:19 +0200297 * You can still supply an alternative definition of
298 * MBEDTLS_PARAM_FAILED(), which may call `assert`.
299 * - If you define a macro MBEDTLS_PARAM_FAILED() before including `config.h`
300 * or you uncomment the definition of MBEDTLS_PARAM_FAILED() in `config.h`,
301 * the library will call the macro that you defined and will not supply
302 * its own version. Note that if MBEDTLS_PARAM_FAILED() calls `assert`,
303 * you need to enable #MBEDTLS_CHECK_PARAMS_ASSERT so that library source
304 * files include `<assert.h>`.
Andrzej Kurekc470b6b2019-01-31 08:20:20 -0500305 *
306 * Uncomment to enable validation of application-controlled parameters.

Andrzej Kurekc470b6b2019-01-31 08:20:20 -0500493 * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_free are
Janos Follathc44ab972016-11-18 16:38:23 +0000494 * called before and after each point operation and provide an opportunity to
495 * implement optimized set up and tear down instructions.
Janos Follathb0697532016-08-18 12:38:46 +0100496 *
Steven Cooreman6226a122021-01-21 13:58:31 +0100497 * Example: In case you set MBEDTLS_ECP_INTERNAL_ALT and
498 * MBEDTLS_ECP_DOUBLE_JAC_ALT, mbed TLS will still provide the ecp_double_jac()
499 * function, but will use your mbedtls_internal_ecp_double_jac() if the group
500 * for the operation is supported by your implementation (i.e. your
501 * mbedtls_internal_ecp_grp_capable() function returns 1 for this group). If the
502 * group is not supported by your implementation, then the original mbed TLS
503 * implementation of ecp_double_jac() is used instead, unless this fallback
504 * behaviour is disabled by setting MBEDTLS_ECP_NO_FALLBACK (in which case
505 * ecp_double_jac() will return MBEDTLS_ERR_ECP_FEATURE_UNAVAILABLE).
506 *
507 * The function prototypes and the definition of mbedtls_ecp_group and
508 * mbedtls_ecp_point will not change based on MBEDTLS_ECP_INTERNAL_ALT, so your

Johan Pascal842d6712020-09-23 13:34:40 +02001649 * through the use_srtp extension.
1650 *
1651 * \note This feature provides the minimum functionality required
1652 * to negotiate the use of DTLS-SRTP and to allow the derivation of
1653 * the associated SRTP packet protection key material.
1654 * In particular, the SRTP packet protection itself, as well as the
1655 * demultiplexing of RTP and DTLS packets at the datagram layer
1656 * (see Section 5 of RFC 5764), are not handled by this feature.
1657 * Instead, after successful completion of a handshake negotiating
1658 * the use of DTLS-SRTP, the extended key exporter API
1659 * mbedtls_ssl_conf_export_keys_ext_cb() should be used to implement
1660 * the key exporter described in Section 4.2 of RFC 5764 and RFC 5705
1661 * (this is implemented in the SSL example programs).
1662 * The resulting key should then be passed to an SRTP stack.
1663 *
1664 * Setting this option enables the runtime API
1665 * mbedtls_ssl_conf_dtls_srtp_protection_profiles()
1666 * through which the supported DTLS-SRTP protection
1667 * profiles can be configured. You must call this API at
1668 * runtime if you wish to negotiate the use of DTLS-SRTP.

3307 * \brief This macro is invoked by the library when an invalid parameter
Gilles Peskinec7ad1222019-06-13 16:44:19 +02003308 * is detected that is only checked with #MBEDTLS_CHECK_PARAMS
Andrzej Kurekc470b6b2019-01-31 08:20:20 -05003309 * (see the documentation of that option for context).
3310 *
Gilles Peskinec7ad1222019-06-13 16:44:19 +02003311 * When you leave this undefined here, the library provides
3312 * a default definition. If the macro #MBEDTLS_CHECK_PARAMS_ASSERT
3313 * is defined, the default definition is `assert(cond)`,
3314 * otherwise the default definition calls a function
3315 * mbedtls_param_failed(). This function is declared in
3316 * `platform_util.h` for the benefit of the library, but
3317 * you need to define in your application.
Andrzej Kurekc470b6b2019-01-31 08:20:20 -05003318 *
3319 * When you define this here, this replaces the default
3320 * definition in platform_util.h (which no longer declares the
3321 * function mbedtls_param_failed()) and it is your responsibility
3322 * to make sure this macro expands to something suitable (in
3323 * particular, that all the necessary declarations are visible
3324 * from within the library - you can ensure that by providing
3325 * them in this file next to the macro definition).
Gilles Peskinec7ad1222019-06-13 16:44:19 +02003326 * If you define this macro to call `assert`, also define
3327 * #MBEDTLS_CHECK_PARAMS_ASSERT so that library source files
3328 * include `<assert.h>`.
Andrzej Kurekc470b6b2019-01-31 08:20:20 -05003329 *
3330 * Note that you may define this macro to expand to nothing, in
3331 * which case you don't have to worry about declarations or
3332 * definitions. However, you will then be notified about invalid
3333 * parameters only in non-void functions, and void function will
3334 * just silently return early on invalid parameters, which
3335 * partially negates the benefits of enabling
3336 * #MBEDTLS_CHECK_PARAMS in the first place, so is discouraged.
