"""Generate an initial set of MeshPackets.
|
|
|
|
The fuzzer uses these MeshPackets as an initial seed of test candidates.
|
|
|
|
It's also good to add any previously discovered crash test cases to this list
|
|
to avoid future regressions.
|
|
|
|
If left unset, the following values will be automatically set by the fuzzer.
|
|
- to: automatically set to the running node's NodeID
|
|
- from: automatically set to the running node's NodeID
|
|
- id: automatically set to the value of an incrementing counter
|
|
|
|
Additionally, if `pki_encrypted` is populated in the packet, the first admin key
|
|
will be copied into the `public_key` field.
