10.10.1. Appendix H thereof.

While communicating with the smart card is considered outside the scope for the -Anjay library, the “bootstrapper” feature, available commercially, implements a -parser for the file format described in section G.3.4 of the Appendix G -mentioned above.

+

The “bootstrapper” feature, available as a commercial extension to the Anjay +library, includes two modules that aid in implementing this part of the +specification:

+
    +

  • bootstrapper implements a parser for the file format described in +section G.3.4 of the Appendix G +mentioned above

    • +

  • sim_bootstrap implements the flow of ISO/IEC 7816-4 commands +necessary to retrieve the aforementioned file

    • +
+

With the above features in place, all that’s left to implement is actual +communication with the smart card, typically sending and receiving AT+CSIM +commands to a cellular modem.

Bootstrapping from smart card has a number of advantages, including:

+
+

10.10.2.2. Enabling and configuring the sim_bootstrap module

+

Similarly, to enable the sim_bootstrap module, you can enable the +ANJAY_WITH_MODULE_SIM_BOOTSTRAP macro in the anjay_config.h file or, if +using CMake, enable the corresponding WITH_MODULE_sim_bootstrap CMake +option. This requires that the bootstrapper feature is also enabled.

+

By default, the module will access the PKCS#15 application directory file and +search it for the EF(DODF-bootstrap) file in a way that is compliant with LwM2M +TS Appendix G mentioned above.

+

However, you can override the OID of the file to look for, by defining the +ANJAY_MODULE_SIM_BOOTSTRAP_DATA_OID_OVERRIDE_HEX macro in anjay_config.h +or setting the corresponding MODULE_sim_bootstrap_DATA_OID_OVERRIDE_HEX +CMake option. It shall be set to a string containing hexlified DER +representation of the desired OID. The default, standards-compliant value is +"672b0901" (which corresponds to OID 2.23.43.9.1), but you may need to +change it to a different value, for example some cards are known to use a +mistakenly encoded value of "0604672b0901".

+

Alternatively, you might define the +ANJAY_MODULE_SIM_BOOTSTRAP_HARDCODED_FILE_ID macro (or set the +MODULE_sim_bootstrap_HARDCODED_FILE_ID CMake option) to bypass the directory +search entirely and set a hardcoded file ID, e.g. 0x6432.

+

Once the module is enabled and configured, you can use the +anjay_sim_bootstrap_stream_create() function to +create an input stream suitable for passing to anjay_bootstrapper(). In the +simplest case, you can also use the anjay_sim_bootstrap_perform() function +that combines both calls and automatically closes the stream as well.

This shares similarities with the restore_objects_if_possible() function
-from the Persistence support tutorial.

-
As mentioned in the Enabling the bootstrapper module section above, to
-perform bootstrap using an actual smart card, the
-avs_stream_simple_input_create() function from the avs_stream_simple_io.h
-header could be used instead of the avs_stream_file_create() call that is
-used here to access regular file system.

+
The sim_perform_command() function is a callback that is passed to the
+sim_bootstrap module logic, and performs the AT+CSIM command over a
+serial port. The modem_getline() function it calls is almost identical to
+the one originally implemented for Non-IP Data Delivery.

+
The bootstrap_from_sim() function itself is a wrapper over
+anjay_sim_bootstrap_perform() that
+additionally initializes and closes the card communication channel.

 update. We can implement it as follows:

     // Reset can be issued even if the download never started.

+    }
 
-    return fw_open_download_file(0);
-}
+    return fw_open_download_file(0);

Then, we can implement storing the download state logic in fw_stream_write:

-
static int fw_stream_write(void *user_ptr, const void *data, size_t length) {
-    (void) user_ptr;
+
static int fw_stream_write(void *user_ptr, const void *data, size_t length) {
+    (void) user_ptr;
     // NOTE: fflush() and fsync() are done to be relatively sure that
     // the data is passed to the hardware and so that we can update
     // resume_offset in the download state. They are suboptimal on UNIX-like
     // platforms, and are used just to illustrate when is the right time to
     // update resume_offset on embedded platforms.
-    if (fwrite(data, length, 1, FW_STATE.firmware_file) != 1
-            || fflush(FW_STATE.firmware_file)
-            || fsync(fileno(FW_STATE.firmware_file))) {
-        fprintf(stderr, "Writing to firmware image failed\n");
-        return -1;
-    }
-    if (FW_STATE.download_state.persisted_uri) {
-        FW_STATE.download_state.resume_offset += length;
-        if (store_download_state(&FW_STATE.download_state)) {
+    if (fwrite(data, length, 1, FW_STATE.firmware_file) != 1
+            || fflush(FW_STATE.firmware_file)
+            || fsync(fileno(FW_STATE.firmware_file))) {
+        fprintf(stderr, "Writing to firmware image failed\n");
+        return -1;
+    }
+    if (FW_STATE.download_state.persisted_uri) {
+        FW_STATE.download_state.resume_offset += length;
+        if (store_download_state(&FW_STATE.download_state)) {
             // If we returned -1 here, the download would be aborted, so it
             // is probably better to continue instead.
-            fprintf(stderr,
-                    "Could not store firmware download state - ignoring\n");
-        }
-    }
-    return 0;
-}
+            fprintf(stderr,
+                    "Could not store firmware download state - ignoring\n");
+        }
+    }
+    return 0;
+}
 

 

 
The next step is to make sure that fw_reset resets the download state as well:

-
static void fw_reset(void *user_ptr) {
+
static void fw_reset(void *user_ptr) {
     // Reset can be issued even if the download never started.
-    if (FW_STATE.firmware_file) {
+    if (FW_STATE.firmware_file) {
         // We ignore the result code of fclose(), as fw_reset() can't fail.
-        (void) fclose(FW_STATE.firmware_file);
+        (void) fclose(FW_STATE.firmware_file);
         // and reset our global state to initial value.
-        FW_STATE.firmware_file = NULL;
-    }
+        FW_STATE.firmware_file = NULL;
+    }
     // Finally, let's remove any downloaded payload
-    unlink(FW_IMAGE_DOWNLOAD_NAME);
+    unlink(FW_IMAGE_DOWNLOAD_NAME);
     // And reset any download state.
-    reset_download_state(&FW_STATE.download_state);
-}
+    reset_download_state(&FW_STATE.download_state);
+}
 

 

 
And the last piece of the implementation would be to read the download state (if any)
 at initialization stage, and before installing the firmware update module in Anjay:

-
int fw_update_install(anjay_t *anjay) {
-    anjay_fw_update_initial_state_t state;
-    memset(&state, 0, sizeof(state));
+
int fw_update_install(anjay_t *anjay) {
+    anjay_fw_update_initial_state_t state;
+    memset(&state, 0, sizeof(state));
 
-    if (access(FW_UPDATED_MARKER, F_OK) != -1) {
+    if (access(FW_UPDATED_MARKER, F_OK) != -1) {
         // marker file exists, it means firmware update succeded!
-        state.result = ANJAY_FW_UPDATE_INITIAL_SUCCESS;
-        unlink(FW_UPDATED_MARKER);
+        state.result = ANJAY_FW_UPDATE_INITIAL_SUCCESS;
+        unlink(FW_UPDATED_MARKER);
         // we can get rid of any download state if the update succeeded
-        reset_download_state(&FW_STATE.download_state);
-    } else if (!restore_download_state(&FW_STATE.download_state)) {
+        reset_download_state(&FW_STATE.download_state);
+    } else if (!restore_download_state(&FW_STATE.download_state)) {
         // download state restored, it means we can try using download
         // resumption
-        if (fw_open_download_file(state.resume_offset)) {
+        if (fw_open_download_file(state.resume_offset)) {
             // the file cannot be opened or seeking failed
-            reset_download_state(&FW_STATE.download_state);
-        } else {
-            state.persisted_uri = FW_STATE.download_state.persisted_uri;
-            state.resume_offset = FW_STATE.download_state.resume_offset;
-            state.resume_etag = FW_STATE.download_state.resume_etag;
-            state.result = ANJAY_FW_UPDATE_INITIAL_DOWNLOADING;
-        }
-    }
+            reset_download_state(&FW_STATE.download_state);
+        } else {

+            state.result = ANJAY_FW_UPDATE_INITIAL_DOWNLOADING;

+    }
     // make sure this module is installed for single Anjay instance only
-    assert(FW_STATE.anjay == NULL);
-    FW_STATE.anjay = anjay;

     // install the module, pass handlers that we implemented and initial state

-    net_socket_impl_t *sock = (net_socket_impl_t *) sock_;

-    if (sock->fd >= 0) {

-        sock->shut_down = true;
-    }
-    return err;

+    if (sock->fd >= 0) {
+        err = shutdown(sock->fd, SHUT_RDWR) ? avs_errno(AVS_EIO) : AVS_OK;
+        sock->shut_down = true;
+    }
+    return err;
+}
 
      
 
      
 
      Similarly, the “get remote hostname” method code is just a simple string copy:
      
-
      static avs_error_t net_remote_hostname(avs_net_socket_t *sock_,
-                                       char *out_buffer,

-                           < 0
-                   ? avs_errno(AVS_UNKNOWN_ERROR)
-                   : AVS_OK;
-}
+
      static avs_error_t net_remote_hostname(avs_net_socket_t *sock_,
+                                       char *out_buffer,
+                                       size_t out_buffer_size) {
+    net_socket_impl_t *sock = (net_socket_impl_t *) sock_;
+    return avs_simple_snprintf(out_buffer, out_buffer_size, "%s",
+                               sock->remote_hostname)
+                           < 0
+                   ? avs_errno(AVS_UNKNOWN_ERROR)
+                   : AVS_OK;
+}
 
      
 
      
 
      Of course the newly implemented functions need to be referenced in the virtual
 method table:

+header is likely to be the easiest way to provide such an implementation, aside
+from using the SIM bootstrap module described below.
+
+Enabling and configuring the sim_bootstrap module
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Similarly, to enable the sim_bootstrap module, you can enable the
+``ANJAY_WITH_MODULE_SIM_BOOTSTRAP`` macro in the ``anjay_config.h`` file or, if
+using CMake, enable the corresponding ``WITH_MODULE_sim_bootstrap`` CMake
+option. This requires that the bootstrapper feature is also enabled.
+
+By default, the module will access the PKCS#15 application directory file and
+search it for the EF(DODF-bootstrap) file in a way that is compliant with LwM2M
+TS Appendix G mentioned above.
+
+However, you can override the OID of the file to look for, by defining the
+``ANJAY_MODULE_SIM_BOOTSTRAP_DATA_OID_OVERRIDE_HEX`` macro in ``anjay_config.h``
+or setting the corresponding ``MODULE_sim_bootstrap_DATA_OID_OVERRIDE_HEX``
+CMake option. It shall be set to a string containing hexlified DER
+representation of the desired OID. The default, standards-compliant value is
+``"672b0901"`` (which corresponds to OID 2.23.43.9.1), but you may need to
+change it to a different value, for example some cards are known to use a
+mistakenly encoded value of ``"0604672b0901"``.
+
+Alternatively, you might define the
+``ANJAY_MODULE_SIM_BOOTSTRAP_HARDCODED_FILE_ID`` macro (or set the
+``MODULE_sim_bootstrap_HARDCODED_FILE_ID`` CMake option) to bypass the directory
+search entirely and set a hardcoded file ID, e.g. ``0x6432``.
+
+Once the module is enabled and configured, you can use the
+`anjay_sim_bootstrap_stream_create()
+<../api/sim__bootstrap_8h.html#a7cd497f30bfc7d36c6f0efb1db1d5a19>`_ function to
+create an input stream suitable for passing to ``anjay_bootstrapper()``. In the
+simplest case, you can also use the `anjay_sim_bootstrap_perform()
+<../api/sim__bootstrap_8h.html#aa94114321f3af6532babde1efd9bdcec>`_ function
+that combines both calls and automatically closes the stream as well.

-`_
-header could be used instead of the ``avs_stream_file_create()`` call that is
-used here to access regular file system.
+The ``bootstrap_from_sim()`` function itself is a wrapper over
+`anjay_sim_bootstrap_perform()
+<../api/sim__bootstrap_8h.html#aa94114321f3af6532babde1efd9bdcec>`_ that
+additionally initializes and closes the card communication channel.

      No other values than the default are valid according to the specification, but some SIM cards are known to use other non-standard values, e.g. "0604672b0901" - including a superfluous nested BER-TLV header, as erroneously illustrated in the EF(DODF-bootstrap) file coding example in LwM2M TS 1.2 and earlier (fixed in LwM2M TS 1.2.1) - which is interpreted as OID 0.6.4.103.43.9.1 (note that it is invalid as the 0.6 tree does not exist in the repository as of writing this note).
