2023-12-24snmp: 5856: fix service removal errorChristian Breunig
When deleting SNMP from CLI the 'delete' key was not honored in the config dictionary, leading to a false process startup causing the following error: Job for snmpd.service failed because the control process exited with error code. See "systemctl status snmpd.service" and "journalctl -xeu snmpd.service" for details. (cherry picked from commit 20b98e780fda4131eb242921884d4955147ce51a)

2023-02-10snmp: T4857: explicitly define default community networks 0.0.0.0/0 and ::/0Christian Breunig
After the RESTRICTED view was introduced snmpd requires a network to be specified. Before adding the RESTRICTED view snmpd always assumed the default network 0.0.0.0/0. This commit re-adds the build in default networks for IPv4 and IPv6 and exposes it as a proper default to the CLI so the user is informed about it: vyos@vyos# set service snmp community foooo Possible completions: authorization Authorization type (default: ro) + client IP address of SNMP client allowed to contact system + network Subnet of SNMP client(s) allowed to contact system (default: 0.0.0.0/0, ::/0)

2023-01-14systemd: T2185: always place generated override files in /runChristian Breunig
This prevents any stale override files when the system is beeing rebooted, but the actual configuration was not saved. /run is a tmpfs and thus always fresh after boot.

2022-02-07FRR: T4020: Updated CLI options processing for FRR daemonszsdc
- Reverted changes from `python/vyos/util.py`. This may lead to unnecessary FRR restart during each boot, depending on a default file content and template, but makes this changeset cleaner. - Fixed typos in node names (extra `>` characters). - Added SNMP module for `isisd` and `ldpd`, since they have it compiled now.

Added first CLI items for controlling FRR daemons parameters that cannot be changed via vtysh and are available via arguments only. Now it is possible to enable/disable modules: SNMP (for each daemon), BMP (for BGP), IRDP (for Zebra).
2021-11-17snmp: T3996: fix invalid IPv6 localhost handling when using listen-addressChristian Poessinger
We need to use a temporary variable when validating the tuple if address is used. If not the else branch will always add the tuple to the list of addresses used for listen-address.

We had two places were the is_ip, is_ipv4 and is_ipv6 helpers had been defined. All places now have been converged into vyos.template as they are used both in the Jinja2 templates and also in our scripts.

2020-07-12snmp: T2687: replace 3rd party hash library with custom codeChristian Poessinger
The 3rd party library used for calculating the SNMP hashes in advance only worked for SHA and nod for MD5 as SHA was hardcoded [1]. The code has been replaced by a class-less implementation providing only the required functionality. [1]: https://github.com/TheMysteriousX/SNMPv3-Hash-Generator/issues/2
2020-07-11snmp: T2687: precalculate snmpv3 encrypted keysChristian Poessinger
As of now when adding new credentials for any SNMPv3 user we submit the credential either plaintext or encrypted. A plaintext credential will be hashed by SNMPd in the background and then passed back into the CLI so it's not stored in cleartext. This feels like the wrong way in changing the CLI content with data produced by a 3rd party daemon which implements the service. It feels like the tail wiggles the entire dog. This should be changed in the following way: - After retrieving the plaintext password from CLI, use Python to hash the key in advance - Re-populate the encrypted key into the CLI and drop the plaintext one - Generate service configuration and continue startup of SNMPd This also fixes a race condition when SNMPd started up but not properly provided the hasehd keys in the configuration resulting in a ConfigurationError. Now as we also support binding SNMPd to a VRF this fixes a deadlock situation on bootup as we can only bind late to the VRF and require up to 5 restarts of the service - but the service will never start.
2020-07-04snmp: vrf: T2682: support restart on failure indefinitely.Christian Poessinger
Linux tries to bind sshd to the VRF but it is yet not ready - for any arbitrary reason. After restarting SSH to often (rate-limiting) it is blocked by systemd. Using Restart/RestartSec is not enough - systemd services use start rate limiting (enabled by default). If service is started more than StartLimitBurst times in StartLimitIntervalSec seconds is it not permitted to start any more. Parameters are inherited from DefaultStartLimitIntervalSec (default 10s) and DefaultStartLimitBurst (default 5).

After migrating PowerDNS to systemd and also its configuration files to a volatile directory in commit 77d725f ("dns-forwarding: T2185: move configuration files to volatile /run directory") the path for the control file has not been altered and pushed to the client rec_control binary"

2020-04-09util: T2226: os.system was wrongly converted to runThomas Mangin
os.system does print the ouput of the command, run() does not. A new function called call() does the printing and return the error code.
2020-04-06util: T2226: covert most calls from os.system to utilThomas Mangin
As little change a possible but the function call The behaviour should be totally unchanged.
