Agoric offer signer endo maker #64

SES_EVAL_REJECTED in protobufjs

tried testing...

fincaps$ endo make src/hdWallet.js -n w1
CapTP cli exception: (RemoteSyntaxError(error:captp:Endo#20001)#1)
RemoteSyntaxError(error:captp:Endo#20001)#1: Possible direct eval expression rejected at <unknown>:12. (SES_EVAL_REJECTED)

  at decodeErrorCommon (packages/marshal/src/marshal.js:281:28)
  at decodeErrorFromCapData (packages/marshal/src/marshal.js:297:14)
  at decodeFromCapData (packages/marshal/src/encodeToCapData.js:404:27)

  at dispatch (packages/captp/src/captp.js:776:7)
  at packages/daemon/src/connection.js:34:7

worker log is not much help:

Endo worker started on pid 167205
Temporary logging of sent error (SyntaxError#1)
SyntaxError#1: Possible direct eval expression rejected at <unknown>:12. (SES_EVAL_REJECTED)

  at rejectSomeDirectEvalExpressions (packages/ses/src/transforms.js:222:9)
  at applyTransforms (packages/ses/src/transforms.js:252:14)
  at safeEvaluate (packages/ses/src/make-safe-evaluator.js:65:14)

so I used the b2zip.sh idiom:

#!/bin/sh
bundle=$1
zip=$2
jq -r .endoZipBase64 b.json| base64 -d > $2

And I found eval in @protobufjs/inquire-v1.1.0/index.js

and then jq -r .source @protobufjs/inquire-v1.1.0/index.js|less -N
to see... sure enough...

   12         var mod = eval("quire".replace(/^/,"re"))(moduleName); // eslint-disable-line no-eval

signing client can `sendTokens`

check balance before:

~/projects/gimix$ yarn docker:make balance-q
$ docker-compose exec agd make -C /workspace balance-q
agd query bank balances agoric1a3zu5aqw255q0tuxzy9aftvgheekw2wedz3xwq
balances:
- amount: "329930000"
  denom: ubld

send tokens using endo:

finquick/packages/fincaps$ make send-tokens
++ Send tokens
endo eval "E(client).sendTokens(\
  'agoric14pfrxg63jn6ha0cp6wxkm4nlvswtscrh2pymwm', \
  'agoric1a3zu5aqw255q0tuxzy9aftvgheekw2wedz3xwq', \
  [{ denom: 'ubld', amount: '12345' }], 'auto').then( \
  tx => tx.code === 0 ? tx.transactionHash : assert.fail(tx.rawLog))" client:validator-client
EABABE9AEF40D07E8185C3E608DE29F9CFECA0B653772FFFC01D299C5FA61EBA

balance after:

~/projects/gimix$ yarn docker:make balance-q
...
balances:
- amount: "329942345"
  denom: ubld

endo smartWallet plugin can query vstorage, execute offers

This endo plug-in has the essential features of a client in the Smart Wallet Dapp Architecture. It can

query the chain to look up things like brands and contract instances
sign and broadcast offers
- track offers until they complete

~/projects/finquick/packages/fincaps$ make reserve-add
++ look up IST in user1 marshal context
endo eval "E(kit.query).lookup('agoricNames', 'brand', 'IST')" -n u1-ist kit:user1-kit
Object [Alleged: IST brand] {}
++ Add to reserve
endo eval "E(reserve).addToReserve(kit.smartWallet, \
  { brand, value: 7_000_000n }, 'add2')" \
  reserve:reserve-tool kit:user1-kit brand:u1-ist
{
  status: {
    id: 'add2',
    invitationSpec: {
      callPipe: [Array],
      instancePath: [Array],
      source: 'agoricContract'
    },
    numWantsSatisfied: 1,
    payouts: { Collateral: [Object] },
    proposal: { give: [Object] },
    result: 'added Collateral to the Reserve'
  },
  tx: {
    height: 270595,
    transactionHash: '4789F93D1BC8262AE8DFB598923BF1267EFED05F287328EC78C888A6EB49EA5C'
  }
}

#64 (comment)

How were you able to get around this?

0xpatrickdev · 2023-11-22T02:33:37Z

packages/fincaps/src/batchQuery.js

+   */
+  const getJSON = (href, options = {}) => {
+    const opts = {
+      keepalive: true,


What does LCD stand for?

Also, curious why you are choosing to use keepalive? My MDN search is not providing helpful clues for this context

The keepalive option can be used to allow the request to outlive the page. Fetch with the keepalive flag is a replacement for the Navigator.sendBeacon() API.

LCD = Light client daemon

I copied keepAlive from something else... IOU some git spelunking.

0xpatrickdev · 2023-11-22T03:01:47Z

packages/fincaps/src/smartWallet.js

+
+  for await (const record of history) {
+    // TODO: mustMatch(record, OfferStatusShape)
+    if (record.updated === 'offerStatus' && record.status.id === id) {


This is a really helpful pattern

0xpatrickdev · 2023-11-22T03:05:23Z

packages/fincaps/src/offerSigner.js

+};
+
+/** @param {import('./secret-tool').PassKey} item */
+const fromPassKey = async item => {


What is PassKey? It seems like secret-tool.js wasn't checked in.... Does this read from a YubiKey? Or does secret-tool just get a secret from process.env?

it's there: secret-tool.js

It lets you access the FreeDesktop Secret Sevice, analogous to keychain.

from the package readme:

Plugins with POLA: Google Sheets, Desktop Secrets, sqlite3

Each of these plugins provdes POLA-shaped access:

...

secret-tool.js - SecretTool.makePasskey(attrs1)
makes a PassKey. From there, E(p).subKey(attrs2)
attenuates access to items with { ...attrs2, ...attrs1 }.

Finally got around to reading this, looks awesome! I would like to port this to gimix, but am not sure I understand how we can preserve all of the security properties created here in the REST api context.

Some questions (from a novice endo-er):

does everything need a compartment? Or just the privileged resources
a. should the fastify instance (makeApp) go in its own compartment?
b. should different fastify “route groups” go in different compartments?
i.e., oracelAccept, sendJobReport, and ghOauth require different powers
where do we grant powers?
a. is there one entry point, or should we make multiple entry points? (In current gimix, there’s just one entry point and one resource (fastify app) created)
b. would the fastify app ever call the steps to load a wallet / signer, or would we just give it a pointer to a highly scoped (yet powerful) function like signAndSubmitJobOfferReport

How were you able to get around [SES_EVAL_REJECTED in protobufjs]?

with --UNSAFE :-/

The protobuf code is fundamentally just moving bits around in memory; it has no need for I/O etc. It's a perfect candidate to run fully confined. But it looks like it might do a direct eval, so I'm running it un-confined, with all the ambient authority of normal node code.
