isOverrunActive(). Once the overrun has been noted, we need to manually reset the state in our converter using resetOverrunActive().
Data truncation
occurs when the selected output converter can’t write all bytes in a data frame to the output file. This can happen if CAN FD data is extracted to a format that only supports up to 8 data bytes, e.g. KME40. This condition is reset by a call to resetStatusTruncated().
New output filename
is a change in the output filename that occurs when the converter creates a new file. This can e.g. be the result of splitting output files (which we will look into briefly later).1 The call to isOutputFilenameNew() will return True when the last converted event resulted in the creation of a new output file. This condition will automatically reset during the next call to convertEvent(). We can get the name of the newly created output file by calling getOutputFilename().[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Let us now create a function that, beside of doing the actual conversion, also looks for the above conditions and prints some informational messages to the user.[/vc_column_text][vc_code_raket language="python" code="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"][/vc_column][/vc_row][vc_row disable_element="yes"][vc_column][vc_column_text]

[/vc_message][vc_accordion active_tab="0" collapsible="yes"][vc_accordion_tab title="Original Article"][vc_single_image image="15486"][vc_message]This blog uses now deprecated functions, see blog "Improved API in Python canlib v1.5" for more information.[/vc_message][vc_column_text]This is the final post in a 3-part series about using the Converter Library (kvlclib) in CANlib SDK:
- Writer formats and properties (1 of 3)
- Converting to plain ASCII (2 of 3)
- Special converter conditions (3 of 3)
kvlcIsOverrunActive(). Once the overrun has been noted, we need to manually reset the state using kvlcResetOverrunActive().
Data truncation occurs when the selected output converter can’t write all bytes in a data frame to the output file. This can happen if CAN FD data is extracted to a format that only supports up to 8 data bytes, e.g. KVLC_FILE_FORMAT_KME40. This condition is reset by a call to kvlcResetStatusTruncated().
New output filename is a change in the output filename occurs when the converter has created a new file, which can be the result when splitting output files (which we will look into briefly later).1 The call to kvlcIsOutputFilenameNew() will return true when the last converted event resulted in the creation of a new output file. This condition will automatically reset during the next call to kvlcConvertEvent(). When a split has occurred, we can get the new output filename by calling kvlcGetOutputFilename().
[/vc_column_text][vc_column_text]Let us now create a function that, beside of doing the actual conversion, also looks for the above conditions and prints some informational messages to the user.[/vc_column_text][vc_code_raket language="python" code="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"][vc_column_text]

- Secure Boot on Linux systems
- Build and install signed Kvaser driver modules
openssl command, we now create a private key and a DER encoded certificate.2 Remember to set the Common Name (CN) field (YOUR_NAME) to something meaningful for a human observer.3 We use kvaser.com as the Common Name in our example.[/vc_column_text][vc_code_raket code="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"][vc_column_text]We now end up with two files.[/vc_column_text][vc_code_raket code="JTI0JTIwbHMlMEFtb2R1bGVzaWduLmRlciUyMG1vZHVsZXNpZ24ucHJpdg=="][vc_raw_html]JTNDYnIlM0U=[/vc_raw_html][/vc_column][/vc_row][vc_row][vc_column][vc_header_raket header_type="h3" header="Import and enroll the public key to the system"][vc_column_text]The next step is to use the mokutil4 command to import the public key so that it can be trusted by the system.

When the bootloader starts, the MOK manager EFI utility should automatically start. On my machine I got a screen with white text on light blue background, telling me to "Press any key to perform MOK management" and "Booting in 10 seconds"5, YMMV. Choose "Enroll MOK", select the key, and enroll the key. We will be asked for the password we set during the import step above. Complete the enrollment steps, then continue with the boot. The Linux kernel will log the keys that are loaded, and we can see our own key with the dmesg command.[/vc_column_text][vc_code_raket code="JTIwJTIwJTI0JTIwZG1lc2clN0NncmVwJTIwJUUyJTgwJTk5RUZJJTNBJTIwTG9hZGVkJTIwY2VydCVFMiU4MCU5OSUwQSUyMCUyMCU1QiUyMCUyMCUyMCUyMDAuNjcxODk3JTVEJTIwRUZJJTNBJTIwTG9hZGVkJTIwY2VydCUyMCVFMiU4MCU5OU1pY3Jvc29mdCUyMFdpbmRvd3MlMjBQcm9kdWN0aW9uJTIwUENBJTIwMjAxMSUzQSUwQWE5MjkwMjM5OGUxNmM0OTc3OGNkOTBmOTllNGY5YWUxN2M1NWFmNTMlRTIlODAlOTklMjBsaW5rZWQlMjB0byUyMCVFMiU4MCU5OS5idWlsdGluX3RydXN0ZWRfa2V5cyVFMiU4MCU5OSUwQSUyMCUyMCU1QiUyMCUyMCUyMCUyMDAuNjcxOTA4JTVEJTIwRUZJJTNBJTIwTG9hZGVkJTIwY2VydCUyMCVFMiU4MCU5OU1pY3Jvc29mdCUyMENvcnBvcmF0aW9uJTIwVUVGSSUyMENBJTIwMjAxMSUzQSUwQTEzYWRiZjQzMDliZDgyNzA5YzhjZDU0ZjMxNmVkNTIyOTg4YTFiZDQlRTIlODAlOTklMjBsaW5rZWQlMjB0byUyMCVFMiU4MCU5OS5idWlsdGluX3RydXN0ZWRfa2V5cyVFMiU4MCU5OSUwQSUyMCUyMCU1QiUyMCUyMCUyMCUyMDAuNjczNzcxJTVEJTIwRUZJJTNBJTIwTG9hZGVkJTIwY2VydCUyMCVFMiU4MCU5OWt2YXNlci5jb20lM0ElMjA3NGZkODkyOWQ5ZTJmYjY0YTliZDBhYmUzYmRmJTBBNDJkNTE5YjczODJmJUUyJTgwJTk5JTIwbGlua2VkJTIwdG8lMjAlRTIlODAlOTkuYnVpbHRpbl90cnVzdGVkX2tleXMlRTIlODAlOTklMEElMjAlMjAlNUIlMjAlMjAlMjAlMjAwLjY3MzkwMiU1RCUyMEVGSSUzQSUyMExvYWRlZCUyMGNlcnQlMjAlRTIlODAlOTlDYW5vbmljYWwlMjBMdGQuJTIwTWFzdGVyJTIwQ2VydGlmaWNhdGUlMjBBdXRob3JpdHklM0ElMEFhZDkxOTkwYmMyMmFiMWY1MTcwNDhjMjNiNjY1NWEyNjhlMzQ1YTYzJUUyJTgwJTk5JTIwbGlua2VkJTIwdG8lMjAlRTIlODAlOTkuYnVpbHRpbl90cnVzdGVkX2tleXMlRTIlODAlOTk="][vc_column_text]We can now also test that our certificate has been enrolled using the mokutil command.[/vc_column_text][vc_code_raket code="JTI0JTIwY2QlMjB+JTJGc2lnbl9jZXJ0JTBBJTI0JTIwbW9rdXRpbCUyMC0tdGVzdC1rZXklMjBtb2R1bGVzaWduLmRlciUwQW1vZHVsZXNpZ24uZGVyJTIwaXMlMjBhbHJlYWR5JTIwZW5yb2xsZWQlMEE="][vc_raw_html]JTNDYnIlM0U=[/vc_raw_html][/vc_column][/vc_row][vc_row][vc_column][vc_header_raket header_type="h3" header="Build, sign and install the modules"][vc_column_text]Before building, we need to download the latest version of linuxcan from the Kvaser download page, which as of this writing is v5.20.6[/vc_column_text][vc_code_raket code="JTI0JTIwd2dldCUyMGh0dHAlM0ElMkYlMkZ3d3cua3Zhc2VyLmNvbSUyRnNvZnR3YXJlJTJGNzMzMDEzMDk4MDc1NCUyRlY1XzIwXzAlMkZsaW51eGNhbi50YXIuZ3olMEElMjQlMjB0YXIlMjB4dnpmJTIwbGludXhjYW4udGFyLmd6JTBBJTI0JTIwY2QlMjBsaW51eGNhbiUwQQ=="][vc_column_text]In order to make it easy for us to sign the files as part of the normal build process, we modify the kv_module target in the file config.mak as follows.7[/vc_column_text][vc_code_raket code="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"][vc_column_text]It is now possible to build and sign the driver modules using the normal make command by just adding the two environment variables KV_SIGN_CERT_PATH and KV_SIGN_CERT_NAME.

2 You can read more about the different X509 file extensions such as DER in the SSL installation knowledge base at https://support.ssl.com/Knowledgebase/Article/View/19/0/der-vs-crt-vs-cer-vs-pem-certificates-and-how-to-convert-them/.
3 For a description of the significance of the Common Name, read more in the stackexchange article at https://security.stackexchange.com/questions/40026/openssl-x509-whats-the-significance-of-cn-common-name/.
4 You use the mokutil command to manage Machine Owner Keys (MOK) used by the shim layer to validate grub2 and kernel images.
5 If you miss this timeout, you need to rerun the mokutil --import command and reboot again.
6 Kvaser download page is located at https://www.kvaser.com/download.
7 The adjusted makefile target will be incorporated in the next release of linuxcan.
8 Unfortunatly it is currently not possible to use modinfo to see if a module is signed or not, see the github issue in coreos at https://github.com/coreos/bugs/issues/1054/ for more information.[/vc_column_text][/vc_column][/vc_row]
