| 44 | * The fixup_args functions are called with the following parameters: |
| 45 | * |
| 46 | * |state| The state we're called in, explained further at the |
| 47 | * end of this comment. |
| 48 | * |translation| The translation item, to be pilfered for data as |
| 49 | * necessary. |
| 50 | * |ctx| The translation context, which contains copies of |
| 51 | * the following arguments, applicable according to |
| 52 | * the caller. All of the attributes in this context |
| 53 | * may be freely modified by the fixup_args function. |
| 54 | * For cleanup, call cleanup_translation_ctx(). |
| 55 | * |
| 56 | * The |state| tells the fixup_args function something about the caller and |
| 57 | * what they may expect: |
| 58 | * |
| 59 | * PKEY The fixup_args function has been called |
| 60 | * from an EVP_PKEY payload getter / setter, |
| 61 | * and is fully responsible for getting or |
| 62 | * setting the requested data. With this |
| 63 | * state, the fixup_args function is expected |
| 64 | * to use or modify |*params|, depending on |
| 65 | * |action_type|. |
| 66 | * |
| 67 | * PRE_CTRL_TO_PARAMS The fixup_args function has been called |
| 68 | * POST_CTRL_TO_PARAMS from EVP_PKEY_CTX_ctrl(), to help with |
| 69 | * translating the ctrl data to an OSSL_PARAM |
| 70 | * element or back. The calling sequence is |
| 71 | * as follows: |
| 72 | * |
| 73 | * 1. fixup_args(PRE_CTRL_TO_PARAMS, ...) |
| 74 | * 2. EVP_PKEY_CTX_set_params() or |
| 75 | * EVP_PKEY_CTX_get_params() |
| 76 | * 3. fixup_args(POST_CTRL_TO_PARAMS, ...) |
| 77 | * |
| 78 | * With the PRE_CTRL_TO_PARAMS state, the |
| 79 | * fixup_args function is expected to modify |
| 80 | * the passed |*params| in whatever way |
| 81 | * necessary, when |action_type == SET|. |
| 82 | * With the POST_CTRL_TO_PARAMS state, the |
| 83 | * fixup_args function is expected to modify |
| 84 | * the passed |p2| in whatever way necessary, |
| 85 | * when |action_type == GET|. |
| 86 | * |
| 87 | * The return value from the fixup_args call |
| 88 | * with the POST_CTRL_TO_PARAMS state becomes |
| 89 | * the return value back to EVP_PKEY_CTX_ctrl(). |
| 90 | * |
| 91 | * CLEANUP_CTRL_TO_PARAMS The cleanup_args functions has been called |
| 92 | * from EVP_PKEY_CTX_ctrl(), to clean up what |
| 93 | * the fixup_args function has done, if needed. |
| 94 | * |
| 95 | * |
| 96 | * PRE_CTRL_STR_TO_PARAMS The fixup_args function has been called |
| 97 | * POST_CTRL_STR_TO_PARAMS from EVP_PKEY_CTX_ctrl_str(), to help with |
| 98 | * translating the ctrl_str data to an |
| 99 | * OSSL_PARAM element or back. The calling |
| 100 | * sequence is as follows: |
| 101 | * |
| 102 | * 1. fixup_args(PRE_CTRL_STR_TO_PARAMS, ...) |
| 103 | * 2. EVP_PKEY_CTX_set_params() or |
| 104 | * EVP_PKEY_CTX_get_params() |
| 105 | * 3. fixup_args(POST_CTRL_STR_TO_PARAMS, ...) |
| 106 | * |
| 107 | * With the PRE_CTRL_STR_TO_PARAMS state, |
| 108 | * the fixup_args function is expected to |
| 109 | * modify the passed |*params| in whatever |
| 110 | * way necessary, when |action_type == SET|. |
| 111 | * With the POST_CTRL_STR_TO_PARAMS state, |
| 112 | * the fixup_args function is only expected |
| 113 | * to return a value. |
| 114 | * |
| 115 | * CLEANUP_CTRL_STR_TO_PARAMS The cleanup_args functions has been called |
| 116 | * from EVP_PKEY_CTX_ctrl_str(), to clean up |
| 117 | * what the fixup_args function has done, if |
| 118 | * needed. |
| 119 | * |
| 120 | * PRE_PARAMS_TO_CTRL The fixup_args function has been called |
| 121 | * POST_PARAMS_TO_CTRL from EVP_PKEY_CTX_get_params() or |
| 122 | * EVP_PKEY_CTX_set_params(), to help with |
| 123 | * translating the OSSL_PARAM data to the |
| 124 | * corresponding EVP_PKEY_CTX_ctrl() arguments |
| 125 | * or the other way around. The calling |
| 126 | * sequence is as follows: |
| 127 | * |
| 128 | * 1. fixup_args(PRE_PARAMS_TO_CTRL, ...) |
| 129 | * 2. EVP_PKEY_CTX_ctrl() |
| 130 | * 3. fixup_args(POST_PARAMS_TO_CTRL, ...) |
| 131 | * |
| 132 | * With the PRE_PARAMS_TO_CTRL state, the |
| 133 | * fixup_args function is expected to modify |
| 134 | * the passed |p1| and |p2| in whatever way |
| 135 | * necessary, when |action_type == SET|. |
| 136 | * With the POST_PARAMS_TO_CTRL state, the |
| 137 | * fixup_args function is expected to |
| 138 | * modify the passed |*params| in whatever |
| 139 | * way necessary, when |action_type == GET|. |
| 140 | * |
| 141 | * CLEANUP_PARAMS_TO_CTRL The cleanup_args functions has been called |
| 142 | * from EVP_PKEY_CTX_get_params() or |
| 143 | * EVP_PKEY_CTX_set_params(), to clean up what |
| 144 | * the fixup_args function has done, if needed. |
