2024-02-02configdict: T5894: preserve old behavior when dealing with PKIChristian Breunig
Commit b152b5202 ("configdict: T5894: add get_config_dict() flag with_pki") added the generic PKI flag but if there was no PKI subsystem available in the configuration, no pki dict key ever manifested in the resulting dictionary requested by the caller. This is different to the old behavior (which each caller implementing the call itself) where there always was a pki key present - even if it was empty. This triggered a bug in the IPSec script Traceback (most recent call last): File "/usr/libexec/vyos/conf_mode/vpn_ipsec.py", line 600, in <module> verify(ipsec) File "/usr/libexec/vyos/conf_mode/vpn_ipsec.py", line 372, in verify verify_pki_rsa(ipsec['pki'], rsa) ~~~~~^^^^^^^ KeyError: 'pki' As it wanted to verify keys, but there was no pki dictionary key available. This commit restores the previous behavior.
2024-01-06pki: T5886: add support for ACME protocol (LetsEncrypt)Christian Breunig
The "idea" of this PR is to add new CLI nodes under the pki subsystem to activate ACME for any given certificate. vyos@vyos# set pki certificate NAME acme Possible completions: + domain-name Domain Name email Email address to associate with certificate listen-address Local IPv4 addresses to listen on rsa-key-size Size of the RSA key (default: 2048) url Remote URL (default: https://acme-v02.api.letsencrypt.org/directory) Users choose if the CLI based custom certificates are used set pki certificate EXAMPLE acme certificate <base64> or if it should be generated via ACME. The ACME server URL defaults to LetsEncrypt but can be changed to their staging API for testing to not get blacklisted. set pki certificate EXAMPLE acme url https://acme-staging-v02.api.letsencrypt.org/directory Certificate retrieval has a certbot --dry-run stage in verify() to see if it can be generated. After successful generation, the certificate is stored in under /config/auth/letsencrypt. Once a certificate is referenced in the CLI (e.g. set interfaces ethernet eth0 eapol certificate EXAMPLE) we call vyos.config.get_config_dict() which will (if with_pki=True is set) blend in the base64 encoded certificate into the JSON data structure normally used when using a certificate set by the CLI. Using this "design" does not need any change to any other code referencing the PKI system, as the base64 encoded certificate is already there. certbot renewal will call the PKI python script to trigger dependency updates.
2024-01-04configdict: T5894: add get_config_dict() flag with_pkiChristian Breunig
VyOS has several services relaying on the PKI CLI tree to retrieve certificates. Consuming services like ethernet, openvpn or ipsec all re-implemented the same code to retrieve the certificates from the CLI. This commit extends the signature of get_config_dict() with a new option with_pki that defaults to false. If this option is set, the PKI CLI tree will be blended into the resulting dictionary.

Drop low-level merge_defaults function in favor of Config method for a middle-grained level of control when merging defaults.

2023-06-22config: T5228: add get_config_defaults options to match get_config_dictJohn Estabrook
For those cases not covered by automatic merging of defaults in get_config_dict(..., with_defaults=True), get_config_defaults should take arguments consistent with those of get_config_dict, for ease of merging results.

2022-04-14config: T4361: correct exists()/exists_effective() on value(s)John Estabrook
The check for existence of value(s) in config.exists relied solely on return_value, causing the return of a false negative on multi-valued nodes; this is corrected. Also, config.exists_effective did no check for existence of values; this is added.

2020-05-05config: T2427: always return copies of listsJernej Jakob
Since lists in python are assigned by reference, taking the return value from these functions and modifying it will modify all other return values of functions that called the function before and did not explicitly copy it. To be safe, always make a copy of lists before returning them.
