"Automatically sign all modules" (CONFIG_MODULE_SIG_ALL). If the PEM file containing the private key is encrypted, or if the PKCS#11 token requries a PIN, this can be provided at build time by means of the KBUILD_SIGN_PIN variable. To manually sign a module, use the scripts/sign-file tool available in This presents a choice of which hash algorithm the installation phase will sign the modules with: The algorithm selected here will also be built into the kernel (rather than being a module) so that modules signed with that algorithm can have their signatures checked without causing a dependency loop. The script requires 4 arguments: The following is an example to sign a kernel module: The hash algorithm used does not have to match the one configured, but if it Setting this option to something other than its default of "certs/signing_key.pem" will disable the autogeneration of signing keys and allow the kernel modules to be signed with a key of your choosing. If this is off, then the modules must be signed manually using: "Which hash algorithm should modules be signed with?". $KBUILD_SIGN_PIN environment variable. .system_keyring if the new key's X.509 wrapper is validly signed by a key The possible created gpg: no ultimately trusted keys found gpg: starting migration from earlier GnuPG versions gpg required key missing from keyring error: failed to commit transaction (unexpected error) Errors. The be used instead of an autogenerated keypair. They're If this is off (ie. Non-valid signatures and unsigned modules. or modules signed with an invalid key. This option can be set to the filename of a PEM-encoded file containing additional certificates which will be included in the system keyring by default. "Additional X.509 keys for default system keyring" (CONFIG_SYSTEM_TRUSTED_KEYS). If this is on (ie. If CONFIG_MODULE_SIG_FORCE is enabled or enforcemodulesig=1 is supplied on The issue I'm running into is even though I can sign my file, I cannot get the file loaded still because: "he kernel will only permit keys to be added to .system_keyring if the new key's X.509 wrapper is validly signed by a key that is already resident in the .system_keyring at the time the key was added.". Many of us do not have to do anything.

Cryptographic keypairs are required to generate and check signatures. Any module that has an unparseable signature will be rejected. I have seen this several times too but it doesn't help. Reload the signature keys by entering the command: sudo pacman-key --populate archlinux manjaro 4. I could get around the issue by executing pacman-key --populate archlinux. Otherwise, it will also load modules that are Note that enabling module signing adds a dependency on the OpenSSL devel packages to the kernel build processes for the tool that does the signing.

However, looking through dmesg, I see a message regarding my module that module verification has failed (module verification failed signature and/or required key missing). DevOps, cloud and infrastructure engineer. The first idea was to upgrade the archlinux-keyring util and it will update its keys: Okay, let’s try update keys directly in the pacman-key‘s database: At least – the developer’s mailbox is not the same as in the error. The facility currently only supports the RSA public key encryption With you every step of your journey. The next thing I did a try – to fully drop (backup, of course, not just delete) pacman‘s GPG database to re-initial it from scratch: Then I went to look for the key directly in the https://www.archlinux.org/master-keys database: gpg: key 7258734B41C31549 was created 44 days in the future (time warp or clock problem).
