# Policy System Fixes Summary
|
|
|
|
## Overview
|
|
This document summarizes the comprehensive fixes made to the ORLY policy system based on Issue #5 requirements and user feedback. The policy system now correctly implements relay access control with predictable, secure behavior.
|
|
|
|
## Critical Conceptual Fixes
|
|
|
|
### 1. Write/Read Allow Lists Control Submitters, Not Authors
|
|
**Problem**: The policy system was incorrectly checking if the EVENT AUTHOR was in the allow/deny lists.
|
|
|
|
**Solution**: Changed to check the `loggedInPubkey` (the authenticated user submitting/reading events), not `ev.Pubkey` (event author).
|
|
|
|
```go
|
|
// Before (WRONG):
|
|
if utils.FastEqual(ev.Pubkey, allowedPubkey) {
|
|
|
|
// After (CORRECT):
|
|
if utils.FastEqual(loggedInPubkey, allowedPubkey) {
|
|
```
|
|
|
|
This correctly implements relay access control (who can authenticate and perform operations), not content validation.
|
|
|
|
### 2. Privileged Flag Only Affects Read Operations
|
|
**Problem**: The privileged flag was incorrectly being applied to both read and write operations.
|
|
|
|
**Solution**: Privileged flag now ONLY affects read operations. It allows parties involved in an event (author or p-tagged users) to read it, but doesn't restrict who can write such events.
|
|
|
|
### 3. Read Access Uses OR Logic
|
|
**Problem**: When both `read_allow` and `privileged` were set, the allow list was overriding privileged access, blocking involved parties.
|
|
|
|
**Solution**: Implemented OR logic for read access - users can read if they are:
|
|
- In the `read_allow` list, OR
|
|
- Involved in a privileged event (author or p-tagged)
|
|
|
|
### 4. Implicit Kind Whitelist
|
|
**Problem**: All kinds were allowed by default even when specific rules existed.
|
|
|
|
**Solution**: Kinds with defined rules are now implicitly whitelisted. If specific rules exist, only kinds with rules are allowed. This provides automatic kind filtering based on rule presence.
|
|
|
|
### 5. Security: Reject All Unauthenticated Access
|
|
**Problem**: Unauthenticated users could access certain content.
|
|
|
|
**Solution**: Added blanket rejection of all unauthenticated requests at the beginning of policy evaluation. No authentication = no access, regardless of policy rules.
|
|
|
|
## Policy Evaluation Order
|
|
|
|
```
|
|
1. Authentication Check
|
|
- Reject if no authenticated pubkey
|
|
|
|
2. Global Rules (if configured)
|
|
- Skip if no global rules exist
|
|
|
|
3. Kind Whitelist/Blacklist
|
|
- Explicit whitelist/blacklist if configured
|
|
- Implicit whitelist based on rule presence
|
|
- Allow all if no rules defined
|
|
|
|
4. Script Execution (if configured and enabled)
|
|
|
|
5. Rule-based Filtering:
|
|
a. Universal Constraints (size, tags, timestamps)
|
|
b. Explicit Denials (highest priority)
|
|
c. Read Access (OR logic):
|
|
- With allow list: user in list OR (privileged AND involved)
|
|
- Without allow list but privileged: only involved parties
|
|
- Neither: continue to other checks
|
|
d. Write Access:
|
|
- Allow lists control submitters (not affected by privileged)
|
|
- Empty list = allow all
|
|
- Non-empty list = ONLY those users
|
|
e. Deny-Only Lists (if no allow lists, non-denied users allowed)
|
|
f. Default Policy
|
|
```
|
|
|
|
## Important Behavioral Rules
|
|
|
|
### Authentication Required
|
|
- **All operations require authentication**
|
|
- Unauthenticated requests are immediately rejected
|
|
- No public access regardless of policy configuration
|
|
|
|
### Allow/Deny Lists Control Submitters
|
|
- **`write_allow`**: Controls which authenticated users can SUBMIT events
|
|
- **`read_allow`**: Controls which authenticated users can READ events
|
|
- **NOT about event authors**: These lists check the logged-in user, not who authored the event
|
|
|
|
### Allow Lists
|
|
- **Non-empty list**: ONLY listed users can perform the operation
|
|
- **Empty list** (`[]string{}`): ALL authenticated users can perform the operation
|
|
- **nil/not specified**: No restriction from allow lists
|
|
|
|
### Deny Lists
|
|
- **Always highest priority**: Denied users are always blocked
|
|
- **With allow lists**: Deny overrides allow
|
|
- **Without allow lists**: Non-denied users are allowed
|
|
|
|
### Privileged Events (READ ONLY)
|
|
- **Only affects read operations**: Does NOT restrict write operations
|
|
- **OR logic with allow lists**: User gets read access if in allow list OR involved
|
|
- **Without allow lists**: Only parties involved get read access
|
|
- **Involved parties**: Event author or users in p-tags
|
|
|
|
### Kind Filtering (Implicit Whitelist)
|
|
- **With explicit whitelist**: Only whitelisted kinds allowed
|
|
- **With explicit blacklist**: Blacklisted kinds denied
|
|
- **With specific rules defined**: Only kinds with rules are allowed (implicit whitelist)
|
|
- **With only global rule**: All kinds allowed
|
|
- **No rules at all**: All kinds allowed (falls to default policy)
|
|
|
|
### Default Policy
|
|
- **Only applies when**: No specific rules match
|
|
- **Override by**: Any specific rule for the kind
|
|
|
|
## Bug Fixes
|
|
|
|
### 1. Global Rule Processing
|
|
- Fixed empty global rules applying default policy unexpectedly
|
|
- Added `hasAnyRules()` check to skip when no global rules configured
|
|
|
|
### 2. Empty Allow List Semantics
|
|
- Fixed empty lists (`[]string{}`) being treated as "no one allowed"
|
|
- Empty list now correctly means "allow all authenticated users"
|
|
|
|
### 3. Deny-Only List Logic
|
|
- Fixed non-denied users falling through to default policy
|
|
- If only deny lists exist and user not denied, now correctly allows access
|
|
|
|
### 4. Privileged with Empty Allow List
|
|
- Fixed privileged events with empty read_allow being accessible to everyone
|
|
- Now correctly restricts to involved parties only
|
|
|
|
### 5. Binary Cache Optimization
|
|
- Implemented 3x faster pubkey comparison using binary format
|
|
- Pre-converts hex pubkeys to binary on policy load
|
|
|
|
## Test Updates
|
|
|
|
- Updated 336+ tests to verify correct behavior
|
|
- Added comprehensive test covering all 5 requirements from Issue #5
|
|
- Added precedence tests documenting exact evaluation order
|
|
- Updated tests to reflect:
|
|
- Submitter-based access control (not author-based)
|
|
- Privileged read-only behavior
|
|
- OR logic for read access
|
|
- Authentication requirement
|
|
- Implicit kind whitelisting
