# Kubernetes Flannel CNI Issue - Valkey Pod Restarts
|
||||
|
||||
## Problem Summary
|
||||
|
||||
The Valkey (Redis-compatible) pod in the `towerops` namespace has restarted **24 times in 28 hours** due to Kubernetes networking issues with the Flannel CNI plugin.
|
||||
|
||||
## Symptoms
|
||||
|
||||
```bash
|
||||
$ kubectl get pods -n towerops | grep valkey
|
||||
valkey-0 1/1 Running 24 (3m36s ago) 28h
|
||||
```
|
||||
|
||||
### Pod Events
|
||||
|
||||
```
|
||||
Warning NodeNotReady Node is not ready
|
||||
Warning FailedCreatePodSandBox Failed to create pod sandbox:
|
||||
rpc error: code = Unknown
|
||||
desc = failed to setup network for sandbox:
|
||||
plugin type="flannel" failed (add):
|
||||
failed to load flannel 'subnet.env' file:
|
||||
open /run/flannel/subnet.env: no such file or directory.
|
||||
Check the flannel pod log for this node.
|
||||
```
|
||||
|
||||
## Root Cause
|
||||
|
||||
The Flannel CNI plugin is unable to find the `/run/flannel/subnet.env` file, which is required for pod network configuration. This file is typically created by the Flannel DaemonSet when it initializes networking on each node.
|
||||
|
||||
## Impact
|
||||
|
||||
1. **Application Errors**: Exq background job processor crashes when Redis connections are dropped
|
||||
2. **Data Loss Risk**: Background jobs may fail or be lost during Redis restarts
|
||||
3. **Degraded Performance**: Constant pod restarts consume cluster resources
|
||||
4. **Monitoring Disruption**: SNMP polling and device monitoring may be delayed
|
||||
|
||||
## Investigation Steps
|
||||
|
||||
### 1. Check Flannel DaemonSet Status
|
||||
|
||||
```bash
|
||||
kubectl get daemonset -n kube-flannel
|
||||
kubectl describe daemonset kube-flannel -n kube-flannel
|
||||
kubectl logs -n kube-flannel -l app=flannel --tail=100
|
||||
```
|
||||
|
||||
### 2. Verify Node Network Configuration
|
||||
|
||||
```bash
|
||||
# SSH to the node where Valkey is running
|
||||
# Check if flannel subnet.env exists
|
||||
ls -la /run/flannel/subnet.env
|
||||
|
||||
# Check flannel network interface
|
||||
ip addr show flannel.1
|
||||
|
||||
# Check flannel routes
|
||||
ip route show | grep flannel
|
||||
```
|
||||
|
||||
### 3. Check CNI Plugin Configuration
|
||||
|
||||
```bash
|
||||
# On the node
|
||||
ls -la /etc/cni/net.d/
|
||||
cat /etc/cni/net.d/*flannel*.conf
|
||||
```
|
||||
|
||||
### 4. Restart Flannel Pods (if needed)
|
||||
|
||||
```bash
|
||||
kubectl delete pods -n kube-flannel -l app=flannel
|
||||
```
|
||||
|
||||
### 5. Check Talos Configuration
|
||||
|
||||
If using Talos Linux, verify CNI configuration in machine config:
|
||||
|
||||
```bash
|
||||
talosctl get machineconfig -n <node-ip>
|
||||
```
|
||||
|
||||
## Potential Solutions
|
||||
|
||||
### Option 1: Restart Flannel DaemonSet
|
||||
|
||||
```bash
|
||||
kubectl rollout restart daemonset/kube-flannel -n kube-flannel
|
||||
```
|
||||
|
||||
### Option 2: Reinstall Flannel
|
||||
|
||||
```bash
|
||||
# Remove existing Flannel
|
||||
kubectl delete -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml
|
||||
|
||||
# Reinstall Flannel
|
||||
kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml
|
||||
```
|
||||
|
||||
### Option 3: Switch to Different CNI Plugin
|
||||
|
||||
Consider migrating to a different CNI plugin if Flannel continues to have issues:
|
||||
- **Cilium** - Advanced networking with eBPF
|
||||
- **Calico** - Feature-rich networking and security
|
||||
- **Weave Net** - Simple overlay network
|
||||
|
||||
### Option 4: Talos-Specific Fix
|
||||
|
||||
If using Talos, ensure CNI configuration in machine config matches Flannel requirements.
|
||||
|
||||
## Workaround (Temporary)
|
||||
|
||||
The application has been updated to handle Redis connection failures gracefully:
|
||||
|
||||
1. **RedisHealthCheck**: Waits for Redis availability before starting Exq
|
||||
2. **ExqSupervisor**: Prevents rapid crash loops with limited restart policy
|
||||
3. **Application continues**: Can function without background jobs if Redis unavailable
|
||||
|
||||
However, this is **not a permanent solution**. The underlying Flannel issue must be resolved.
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Check Valkey Status
|
||||
|
||||
```bash
|
||||
# Check pod restart count
|
||||
kubectl get pod valkey-0 -n towerops -o jsonpath='{.status.containerStatuses[0].restartCount}'
|
||||
|
||||
# Check recent events
|
||||
kubectl get events -n towerops --field-selector involvedObject.name=valkey-0 --sort-by='.lastTimestamp'
|
||||
|
||||
# Check logs
|
||||
kubectl logs -n towerops valkey-0 --tail=50
|
||||
```
|
||||
|
||||
### Check Application Redis Errors
|
||||
|
||||
```bash
|
||||
# Check application logs for Redis connection errors
|
||||
kubectl logs -n towerops deployment/towerops | grep -i "redis\|exq"
|
||||
```

|
||||
|
||||
## Solution Implemented
|
||||
|
||||
### Root Cause Analysis
|
||||
|
||||
The issue was **not** a Flannel failure, but a **race condition** during node restarts:
|
||||
|
||||
1. When nodes restart or Flannel pods restart, there's a brief window where `/run/flannel/subnet.env` doesn't exist yet
|
||||
2. Valkey (and other pods) with default priority can start during this window
|
||||
3. CNI plugin fails because subnet.env isn't available yet
|
||||
4. Pods fail to create network sandbox and retry
|
||||
5. By the time Flannel finishes initializing (writes subnet.env), pods succeed on retry
|
||||
|
||||
This explains why:
|
||||
- Flannel logs showed successful initialization
|
||||
- Valkey eventually stabilized after restarts
|
||||
- Issue only occurred during node/pod restart events
|
||||
|
||||
### Fixes Implemented
|
||||
|
||||
#### 1. Application-Level Resilience (Commit: 8ff0c44)
|
||||
|
||||
Added Redis health checks and Exq supervisor improvements:
|
||||
- **RedisHealthCheck module**: Waits for Redis availability before starting Exq
|
||||
- **ExqSupervisor**: Prevents rapid crash loops with limited restart policy
|
||||
- **Benefit**: Application continues functioning even during Redis connection issues
|
||||
|
||||
#### 2. Infrastructure Fix (Commit: 30a0b9a)
|
||||
|
||||
Added `priorityClassName: system-cluster-critical` to Valkey StatefulSet:
|
||||
- Gives Valkey same priority as etcd, coredns, and other cluster services
|
||||
- Scheduler ensures CNI is fully ready before starting Valkey
|
||||
- Significantly reduces race condition window
|
||||
|
||||
### Verification
|
||||
|
||||
Monitor Valkey restart count over next 24-48 hours:
|
||||
|
||||
```bash
|
||||
# Check restart count
|
||||
kubectl get pod valkey-0 -n towerops -o jsonpath='{.status.containerStatuses[0].restartCount}'
|
||||
|
||||
# Monitor for new restart events
|
||||
kubectl get events -n towerops --field-selector involvedObject.name=valkey-0 --watch
|
||||
```
|
||||
|
||||
**Expected Result**: Restart count should remain stable at 0 even during Flannel pod restarts.
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. ✅ **Application fixes deployed** - Added Redis health checks and error handling
|
||||
2. ✅ **Root cause identified** - Race condition during CNI initialization
|
||||
3. ✅ **Infrastructure fix applied** - Added priority class to Valkey
|
||||
4. ⏳ **Monitor stability** - Verify no restarts over 24-48 hours
|
||||
5. ⏳ **Apply to other critical pods** - Consider adding priority classes to towerops deployment
|
||||

# Security Analysis and Mitigations
|
||||
|
||||
This document tracks Sobelow security findings and the mitigations applied to address them.
|
||||
|
||||
## Summary
|
||||
|
||||
As of 2026-02-01, the following high-confidence security issues have been addressed:
|
||||
|
||||
- ✅ **Config.CSP**: Content-Security-Policy headers configured
|
||||
- ✅ **Config.HTTPS**: HTTPS enforcement enabled in production
|
||||
- ✅ **Traversal.FileModule**: Directory traversal protections added to MIB controller
|
||||
- ⚠️ **Vendored Libraries**: Low-risk warnings in SnmpKit (vendored library)
|
||||
|
||||
---
|
||||
|
||||
## Fixed Issues
|
||||
|
||||
### 1. Config.CSP: Missing Content-Security-Policy (FIXED)
|
||||
|
||||
**Severity**: High
|
||||
**Location**: `lib/towerops_web/router.ex:19`
|
||||
**Status**: ✅ Fixed
|
||||
|
||||
**Mitigation**:
|
||||
Added Content-Security-Policy headers to the `:browser` pipeline with LiveView-compatible settings:
|
||||
|
||||
```elixir
|
||||
plug :put_secure_browser_headers, %{
|
||||
"content-security-policy" =>
|
||||
"default-src 'self'; " <>
|
||||
"script-src 'self' 'unsafe-inline' 'unsafe-eval'; " <>
|
||||
"style-src 'self' 'unsafe-inline'; " <>
|
||||
"img-src 'self' data: https:; " <>
|
||||
"font-src 'self' data:; " <>
|
||||
"connect-src 'self' ws: wss:; " <>
|
||||
"frame-ancestors 'none';"
|
||||
}
|
||||
```
|
||||
|
||||
**Note**: `'unsafe-inline'` for scripts is required for Phoenix LiveView to function. This is a documented requirement for LiveView applications.
|
||||
|
||||
---
|
||||
|
||||
### 2. Config.HTTPS: HTTPS Not Enabled (FIXED)
|
||||
|
||||
**Severity**: High
|
||||
**Location**: `config/prod.exs`
|
||||
**Status**: ✅ Fixed
|
||||
|
||||
**Mitigation**:
|
||||
Configured `force_ssl` in production endpoint configuration (`config/runtime.exs`):
|
||||
|
||||
```elixir
|
||||
config :towerops, ToweropsWeb.Endpoint,
|
||||
force_ssl: [
|
||||
hsts: true,
|
||||
rewrite_on: [:x_forwarded_host, :x_forwarded_port, :x_forwarded_proto]
|
||||
]
|
||||
```
|
||||
|
||||
**Security Benefits**:
|
||||
- Automatically redirects HTTP → HTTPS
|
||||
- Enables HSTS (HTTP Strict Transport Security)
|
||||
- Respects X-Forwarded-* headers from reverse proxy (Traefik)
|
||||
|
||||
---
|
||||
|
||||
### 3. Traversal.FileModule: Directory Traversal in MIB Controller (FIXED)
|
||||
|
||||
**Severity**: High
|
||||
**Locations**:
|
||||
- `lib/towerops_web/controllers/api/v1/mib_controller.ex:119` (File.rm_rf)
|
||||
- `lib/towerops_web/controllers/api/v1/mib_controller.ex:229` (File.cp)
|
||||
|
||||
**Status**: ✅ Fixed
|
||||
|
||||
**Mitigation**:
|
||||
Added comprehensive input validation to prevent directory traversal attacks:
|
||||
|
||||
#### Vendor Name Validation
|
||||
```elixir
|
||||
defp validate_vendor_name(vendor) when is_binary(vendor) do
|
||||
# Reject path traversal characters
|
||||
if String.contains?(vendor, [".", "/", "\\", ":"]) do
|
||||
{:error, "Invalid vendor name: cannot contain path separators or dots"}
|
||||
else
|
||||
# Only allow alphanumeric, hyphen, underscore
|
||||
if vendor =~ ~r/^[a-zA-Z0-9_-]+$/ do
|
||||
:ok
|
||||
else
|
||||
{:error, "Invalid vendor name: must contain only letters, numbers, hyphens, and underscores"}
|
||||
end
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
#### Filename Validation
|
||||
```elixir
|
||||
defp validate_filename(filename) when is_binary(filename) do
|
||||
# Reject directory traversal sequences
|
||||
if String.contains?(filename, ["..", "/", "\\"]) or String.starts_with?(filename, ".") do
|
||||
{:error, "Invalid filename: cannot contain path separators or parent directory references"}
|
||||
else
|
||||
:ok
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
**Additional Protections**:
|
||||
- All vendor names validated before path construction
|
||||
- Filenames sanitized with `Path.basename/1`
|
||||
- Superuser-only API access required for all MIB management endpoints
|
||||
- All operations logged for audit trail
|
||||
|
||||
---
|
||||
|
||||
## Remaining Low-Risk Findings
|
||||
|
||||
### Vendored Library Warnings (SnmpKit)
|
||||
|
||||
**Severity**: Low Confidence
|
||||
**Status**: ⚠️ Accepted Risk
|
||||
|
||||
The following warnings are in the vendored `SnmpKit` library (`lib/snmpkit/`):
|
||||
|
||||
#### Misc.BinToTerm: Unsafe `binary_to_term`
|
||||
- **Location**: `lib/snmpkit/snmp_lib/mib/compiler.ex:203`
|
||||
- **Risk Level**: Medium-High
|
||||
- **Reason**: Used for loading compiled MIB files from trusted sources only
|
||||
- **Mitigation**: MIB files are only loaded from the application's `priv/mibs/` directory, which is controlled by administrators. No user-provided binary data is deserialized.
|
||||
|
||||
#### DOS.StringToAtom / DOS.ListToAtom
|
||||
- **Locations**: Multiple files in `lib/snmpkit/snmp_lib/` and `lib/snmpkit/snmp_mgr/`
|
||||
- **Risk Level**: Low
|
||||
- **Reason**: SNMP MIB parsing and tokenization
|
||||
- **Mitigation**: MIB files are from trusted vendor sources and validated before processing. Atom creation is bounded by the finite set of SNMP OID names in standard MIBs.
|
||||
|
||||
#### Traversal.FileModule
|
||||
- **Locations**: MIB parser and compiler files
|
||||
- **Risk Level**: Low
|
||||
- **Reason**: MIB file reading from trusted directories
|
||||
- **Mitigation**: File paths are constructed from application-controlled base directories (`priv/mibs/`). User input does not directly influence file paths.
|
||||
|
||||
#### SQL.Query: SQL injection
|
||||
- **Locations**: `lib/towerops/monitoring.ex` (multiple functions)
|
||||
- **Risk Level**: Very Low (False Positive)
|
||||
- **Reason**: Uses parameterized queries with string interpolation only for table/column names
|
||||
- **Mitigation**: Table names are hardcoded constants, not user input. All user values use proper `$1`, `$2` parameter binding.
|
||||
|
||||
---
|
||||
|
||||
## Ignored Low-Confidence Warnings
|
||||
|
||||
The following warnings have been reviewed and determined to be false positives:
|
||||
|
||||
### XSS.Raw in API Documentation
|
||||
- **Location**: `lib/towerops_web/controllers/api_docs_html/index.html.heex`
|
||||
- **Reason**: Uses `raw(~S"""...""")` to display static code examples in API documentation
|
||||
- **Risk**: None - all content is static, developer-authored code examples
|
||||
- **No Action Required**
|
||||
|
||||
---
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
### File Upload Security
|
||||
1. ✅ Validate all filenames and vendor names
|
||||
2. ✅ Use `Path.basename/1` to strip directory components
|
||||
3. ✅ Restrict operations to predefined base directories
|
||||
4. ✅ Require superuser authentication for file management
|
||||
5. ✅ Log all file operations for audit trail
|
||||
|
||||
### HTTPS Configuration
|
||||
1. ✅ Force SSL with HSTS enabled
|
||||
2. ✅ Respect X-Forwarded-* headers from reverse proxy
|
||||
3. ✅ Use secure cipher suites (default Phoenix configuration)
|
||||
|
||||
### Content Security Policy
|
||||
1. ✅ Default to 'self' for all resources
|
||||
2. ✅ Allow WebSocket connections for LiveView
|
||||
3. ✅ Prevent framing with `frame-ancestors 'none'`
|
||||
4. ⚠️ Allow `'unsafe-inline'` scripts (required for LiveView)
|
||||
|
||||
---
|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
### Manual Security Testing
|
||||
- [ ] Test MIB upload with path traversal attempts (`../../../etc/passwd`)
|
||||
- [ ] Verify HTTPS redirect in production environment
|
||||
- [ ] Test CSP headers don't break LiveView functionality
|
||||
- [ ] Verify file upload restrictions (filename validation)
|
||||
|
||||
### Automated Testing
|
||||
- Run `mix sobelow` regularly in CI/CD pipeline
|
||||
- Monitor for new security vulnerabilities in dependencies
|
||||
- Use Dialyzer for type safety checks
|
||||
|
||||
---
|
||||
|
||||
## Future Improvements
|
||||
|
||||
1. **Stricter CSP**: Explore using nonces for scripts instead of `'unsafe-inline'` (requires LiveView 1.0+)
|
||||
2. **File Upload Limits**: Add file size limits for MIB uploads
|
||||
3. **Rate Limiting**: Implement rate limiting on API endpoints
|
||||
4. **Security Headers**: Add additional security headers (Permissions-Policy, etc.)
|
||||
5. **Dependency Scanning**: Set up automated dependency vulnerability scanning
|
||||

# Firmware Version Tracking System Design
|
||||
|
||||
**Date:** 2026-02-01
|
||||
**Status:** Draft
|
||||
**Target:** MikroTik initially, extensible to all vendors
|
||||
|
||||
## Overview
|
||||
|
||||
Implement a firmware version tracking system that:
|
||||
1. Fetches latest stable firmware versions from vendor sources (MikroTik RSS feed initially)
|
||||
2. Tracks firmware version changes over time with audit logging
|
||||
3. Displays update indicators on device detail pages with download links
|
||||
4. Supports multiple vendors through polymorphic design
|
||||
|
||||
## Database Schema
|
||||
|
||||
### New Tables
|
||||
|
||||
#### 1. `firmware_releases` - Latest available firmware versions
|
||||
|
||||
Stores the most recent stable firmware version for each vendor/product line.
|
||||
|
||||
```elixir
|
||||
create table(:firmware_releases, primary_key: false) do
|
||||
add :id, :binary_id, primary_key: true
|
||||
add :vendor, :string, null: false # "mikrotik", "cisco", "ubiquiti"
|
||||
add :product_line, :string # "routeros", "ios-xe", "unifi", null for single product vendors
|
||||
add :version, :string, null: false # "7.14.1", "17.9.4a"
|
||||
add :release_date, :date # When this version was released
|
||||
add :download_url, :string # Official download page URL
|
||||
add :changelog_url, :string # Release notes URL
|
||||
add :metadata, :map, default: %{} # JSON: RSS item data, API response, etc.
|
||||
add :fetched_at, :utc_datetime, null: false # When we last fetched this
|
||||
|
||||
timestamps(type: :utc_datetime)
|
||||
end
|
||||
|
||||
# Unique constraint: one current version per vendor/product_line
|
||||
create unique_index(:firmware_releases, [:vendor, :product_line])
|
||||
```
|
||||
|
||||
**Design Notes:**
|
||||
- `vendor` is lowercase string for consistency ("mikrotik", not "MikroTik")
|
||||
- `product_line` allows vendors with multiple firmware branches (Cisco IOS vs IOS-XE, MikroTik RouterOS vs SwOS)
|
||||
- `metadata` stores raw source data for debugging and future feature extraction
|
||||
- Single record per vendor/product_line, updated in place when new version detected
|
||||
|
||||
#### 2. `device_firmware_history` - Version change audit trail
|
||||
|
||||
Tracks when devices change firmware versions.
|
||||
|
||||
```elixir
|
||||
create table(:device_firmware_history, primary_key: false) do
|
||||
add :id, :binary_id, primary_key: true
|
||||
add :snmp_device_id, references(:snmp_devices, type: :binary_id, on_delete: :delete_all), null: false
|
||||
add :old_version, :string # Previous version (null for first discovery)
|
||||
add :new_version, :string, null: false # New version detected
|
||||
add :detected_at, :utc_datetime, null: false # When the change was detected
|
||||
add :detection_method, :string # "discovery", "polling", "manual"
|
||||
|
||||
timestamps(type: :utc_datetime, updated_at: false)
|
||||
end
|
||||
|
||||
create index(:device_firmware_history, [:snmp_device_id, :detected_at])
|
||||
create index(:device_firmware_history, [:detected_at])
|
||||
```
|
||||
|
||||
**Design Notes:**
|
||||
- Links to `snmp_devices` (not `devices`) since firmware is SNMP-discovered data
|
||||
- `old_version` nullable for initial discovery (no previous version)
|
||||
- `detected_at` separate from `inserted_at` to record actual change time vs when we logged it
|
||||
- Index on `snmp_device_id + detected_at` for efficient device history queries
|
||||
- Cascading delete: history removed when SNMP device deleted
|
||||
|
||||
### Schema Modifications
|
||||
|
||||
No changes to existing `snmp_devices` table needed - the existing `firmware_version` field remains as the "current version" source of truth.
|
||||
|
||||
## RSS Fetching Implementation
|
||||
|
||||
### Oban Worker: `FirmwareVersionFetcherWorker`
|
||||
|
||||
**Location:** `lib/towerops/workers/firmware_version_fetcher_worker.ex`
|
||||
|
||||
```elixir
|
||||
defmodule Towerops.Workers.FirmwareVersionFetcherWorker do
|
||||
use Oban.Worker, queue: :maintenance, max_attempts: 3
|
||||
require Logger
|
||||
|
||||
@impl Oban.Worker
|
||||
def perform(%Oban.Job{}) do
|
||||
Logger.info("Starting firmware version fetch")
|
||||
|
||||
# Fetch each vendor's latest firmware
|
||||
results = [
|
||||
fetch_mikrotik_routeros(),
|
||||
# Future: fetch_cisco_ios(),
|
||||
# Future: fetch_ubiquiti_unifi()
|
||||
]
|
||||
|
||||
case Enum.all?(results, &match?(:ok, &1)) do
|
||||
true -> :ok
|
||||
false -> {:error, "One or more firmware fetches failed"}
|
||||
end
|
||||
end
|
||||
|
||||
defp fetch_mikrotik_routeros do
|
||||
# Implementation details below
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
**Cron Schedule:** Daily at 2:00 AM
|
||||
|
||||
Add to `config/dev.exs` and `config/runtime.exs` (production):
|
||||
|
||||
```elixir
|
||||
config :towerops, Oban,
|
||||
plugins: [
|
||||
{Oban.Plugins.Cron,
|
||||
crontab: [
|
||||
# ... existing cron jobs ...
|
||||
{"0 2 * * *", Towerops.Workers.FirmwareVersionFetcherWorker}
|
||||
]}
|
||||
]
|
||||
```
|
||||
|
||||
### MikroTik RSS Parsing
|
||||
|
||||
**RSS URL:** `https://cdn.mikrotik.com/routeros/latest-stable.rss`
|
||||
|
||||
**Sample RSS Structure:**
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<rss version="2.0">
|
||||
<channel>
|
||||
<title>RouterOS latest stable version</title>
|
||||
<item>
|
||||
<title>7.14.1</title>
|
||||
<link>https://mikrotik.com/download</link>
|
||||
<pubDate>Wed, 15 Jan 2025 12:00:00 +0000</pubDate>
|
||||
<description>RouterOS 7.14.1 stable release</description>
|
||||
</item>
|
||||
</channel>
|
||||
</rss>
|
||||
```
|
||||
|
||||
**Parsing Implementation:**
|
||||
|
||||
```elixir
|
||||
defp fetch_mikrotik_routeros do
|
||||
url = "https://cdn.mikrotik.com/routeros/latest-stable.rss"
|
||||
|
||||
with {:ok, %{status: 200, body: body}} <- Req.get(url),
|
||||
{:ok, parsed} <- parse_mikrotik_rss(body),
|
||||
{:ok, _release} <- upsert_firmware_release(parsed) do
|
||||
Logger.info("Successfully fetched MikroTik RouterOS: #{parsed.version}")
|
||||
:ok
|
||||
else
|
||||
{:error, reason} = error ->
|
||||
Logger.error("Failed to fetch MikroTik firmware: #{inspect(reason)}")
|
||||
error
|
||||
end
|
||||
end
|
||||
|
||||
defp parse_mikrotik_rss(xml_body) do
|
||||
# Use :xmerl or SweetXml library
|
||||
import SweetXml
|
||||
|
||||
try do
|
||||
version = xml_body |> xpath(~x"//item/title/text()"s) |> String.trim()
|
||||
link = xml_body |> xpath(~x"//item/link/text()"s) |> String.trim()
|
||||
pub_date_str = xml_body |> xpath(~x"//item/pubDate/text()"s) |> String.trim()
|
||||
|
||||
release_date = parse_rfc822_date(pub_date_str)
|
||||
|
||||
{:ok, %{
|
||||
vendor: "mikrotik",
|
||||
product_line: "routeros",
|
||||
version: version,
|
||||
release_date: release_date,
|
||||
download_url: link,
|
||||
changelog_url: "https://mikrotik.com/download/changelogs",
|
||||
metadata: %{
|
||||
rss_title: version,
|
||||
rss_description: xml_body |> xpath(~x"//item/description/text()"s)
|
||||
}
|
||||
}}
|
||||
rescue
|
||||
e -> {:error, "XML parsing failed: #{inspect(e)}"}
|
||||
end
|
||||
end
|
||||
|
||||
defp parse_rfc822_date(date_str) do
|
||||
# "Wed, 15 Jan 2025 12:00:00 +0000" -> ~D[2025-01-15]
|
||||
case Timex.parse(date_str, "{RFC822}") do
|
||||
{:ok, datetime} -> DateTime.to_date(datetime)
|
||||
_ -> Date.utc_today() # Fallback to today if parse fails
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
**Dependencies:**
|
||||
- Add `{:sweet_xml, "~> 0.7"}` to `mix.exs` for XML parsing
|
||||
- Use existing `:req` for HTTP (already in project)
|
||||
- Add `{:timex, "~> 3.7"}` for RFC822 date parsing (or use standard library alternative)
|
||||
|
||||
### Database Upsert Logic
|
||||
|
||||
```elixir
|
||||
defp upsert_firmware_release(attrs) do
|
||||
import Ecto.Query
|
||||
|
||||
# Use ON CONFLICT to update existing record
|
||||
%Towerops.Devices.FirmwareRelease{}
|
||||
|> Towerops.Devices.FirmwareRelease.changeset(attrs)
|
||||
|> Towerops.Repo.insert(
|
||||
on_conflict: {:replace_all_except, [:id, :inserted_at]},
|
||||
conflict_target: [:vendor, :product_line]
|
||||
)
|
||||
end
|
||||
```
|
||||
|
||||
## Version Change Detection
|
||||
|
||||
### Integration Point: Discovery Flow
|
||||
|
||||
**File:** `lib/towerops/snmp/discovery.ex`
|
||||
|
||||
**Current Flow:**
|
||||
1. `run_discovery/1` orchestrates discovery stages
|
||||
2. `build_device_info/3` extracts firmware version from SNMP
|
||||
3. `upsert_device/2` updates/inserts SNMP device record
|
||||
|
||||
**New Logic:** Add version change detection in `upsert_device/2`
|
||||
|
||||
```elixir
|
||||
defp upsert_device(device, device_info) do
|
||||
# Fetch current version BEFORE update
|
||||
current_version = get_current_firmware_version(device.id)
|
||||
new_version = device_info[:firmware_version]
|
||||
|
||||
# Perform existing upsert
|
||||
result =
|
||||
device
|
||||
|> SnmpDevice.changeset(device_info)
|
||||
|> Repo.insert_or_update()
|
||||
|
||||
# Detect and log version change
|
||||
case result do
|
||||
{:ok, snmp_device} ->
|
||||
if version_changed?(current_version, new_version) do
|
||||
log_firmware_change(snmp_device.id, current_version, new_version)
|
||||
end
|
||||
{:ok, snmp_device}
|
||||
|
||||
error -> error
|
||||
end
|
||||
end
|
||||
|
||||
defp get_current_firmware_version(device_id) do
|
||||
case Repo.get_by(SnmpDevice, device_id: device_id) do
|
||||
nil -> nil
|
||||
snmp_device -> snmp_device.firmware_version
|
||||
end
|
||||
end
|
||||
|
||||
defp version_changed?(nil, new_version) when is_binary(new_version), do: false # Initial discovery
|
||||
defp version_changed?(old, new) when old == new, do: false
|
||||
defp version_changed?(old, new) when is_binary(old) and is_binary(new), do: true
|
||||
defp version_changed?(_, _), do: false
|
||||
```
|
||||
|
||||
### Firmware Change Logging
|
||||
|
||||
**File:** `lib/towerops/devices/firmware.ex` (new context module)
|
||||
|
||||
```elixir
|
||||
defmodule Towerops.Devices.Firmware do
|
||||
import Ecto.Query
|
||||
alias Towerops.Repo
|
||||
alias Towerops.Devices.DeviceFirmwareHistory
|
||||
|
||||
def log_firmware_change(snmp_device_id, old_version, new_version) do
|
||||
attrs = %{
|
||||
snmp_device_id: snmp_device_id,
|
||||
old_version: old_version,
|
||||
new_version: new_version,
|
||||
detected_at: DateTime.utc_now(),
|
||||
detection_method: "discovery"
|
||||
}
|
||||
|
||||
%DeviceFirmwareHistory{}
|
||||
|> DeviceFirmwareHistory.changeset(attrs)
|
||||
|> Repo.insert()
|
||||
|> case do
|
||||
{:ok, history} ->
|
||||
# Create audit log entry
|
||||
create_audit_log(history)
|
||||
|
||||
# Broadcast to device topic for real-time updates
|
||||
broadcast_firmware_change(snmp_device_id, old_version, new_version)
|
||||
|
||||
{:ok, history}
|
||||
|
||||
error -> error
|
||||
end
|
||||
end
|
||||
|
||||
defp create_audit_log(history) do
|
||||
# Use existing audit log system if available
|
||||
# Or create device event
|
||||
Logger.info("Firmware changed on device #{history.snmp_device_id}: #{history.old_version} -> #{history.new_version}")
|
||||
end
|
||||
|
||||
defp broadcast_firmware_change(snmp_device_id, old_version, new_version) do
|
||||
Phoenix.PubSub.broadcast(
|
||||
Towerops.PubSub,
|
||||
"device:#{snmp_device_id}",
|
||||
{:firmware_changed, snmp_device_id, old_version, new_version}
|
||||
)
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
## Version Comparison Logic
|
||||
|
||||
### Semantic Version Parser
|
||||
|
||||
**File:** `lib/towerops/devices/version_comparator.ex`
|
||||
|
||||
```elixir
|
||||
defmodule Towerops.Devices.VersionComparator do
|
||||
@moduledoc """
|
||||
Semantic version comparison for firmware versions.
|
||||
|
||||
Handles common formats:

|
||||
- X.Y (7.14)
|
||||
- X.Y.Z-suffix (7.14.1-beta)
|
||||
"""
|
||||
|
||||
def compare(version1, version2) do
|
||||
parsed1 = parse_version(version1)
|
||||
parsed2 = parse_version(version2)
|
||||
|
||||
do_compare(parsed1, parsed2)
|
||||
end
|
||||
|
||||
def newer?(current, available) do
|
||||
compare(current, available) == :lt
|
||||
end
|
||||
|
||||
defp parse_version(version) when is_binary(version) do
|
||||
# Remove common prefixes
|
||||
cleaned = version
|
||||

|> String.split(["-", " "], parts: 2)
|
||||
|> List.first()
|
||||
|> String.split(".")
|
||||
|> Enum.map(&String.to_integer/1)
|
||||
|
||||
# Pad to [major, minor, patch] format
|
||||
case parts do
|
||||
[major, minor, patch] -> {major, minor, patch}
|
||||
[major, minor] -> {major, minor, 0}
|
||||
[major] -> {major, 0, 0}
|
||||
_ -> {0, 0, 0}
|
||||
end
|
||||
rescue
|
||||
_ -> {0, 0, 0} # Invalid version defaults to 0.0.0
|
||||
end
|

```
|

```
|
||||
|
||||
## LiveView Integration
|
||||
|
||||
### Device Detail Page Updates
|
||||
|
||||
**File:** `lib/towerops_web/live/device_live/show.ex`
|
||||
|
||||
**Add to mount/assigns:**
|
||||
|
||||
```elixir
|
||||
def mount(%{"id" => id}, _session, socket) do
|
||||
# ... existing code ...
|
||||
|
||||
socket = socket
|
||||
# ... existing assigns ...
|
||||
|> assign(:available_firmware, nil) # Will be loaded on first refresh
|
||||
|> load_available_firmware() # New helper
|
||||
|
||||
{:ok, socket}

## Extensibility for Future Vendors
|
||||
|
||||
### Adding Cisco IOS Support (Example)
|
||||
|
||||
**1. Add fetch function to worker:**
|
||||
|
||||
```elixir
|
||||
# In FirmwareVersionFetcherWorker
|
||||
defp fetch_cisco_ios do
|
||||
# Cisco uses different mechanism - maybe API or web scraping
|
||||
url = "https://software.cisco.com/download/latest/ios-xe"
|
||||
|
||||
with {:ok, %{status: 200, body: body}} <- Req.get(url, headers: [{"Accept", "application/json"}]),
|
||||
{:ok, parsed} <- parse_cisco_api(body),
|
||||
{:ok, _release} <- Towerops.Devices.Firmware.upsert_firmware_release(parsed) do
|
||||
:ok
|
||||
end
|
||||
end
|
||||
|
||||
defp parse_cisco_api(json_body) do
|
||||
# Vendor-specific parsing
|
||||
data = Jason.decode!(json_body)
|
||||
|
||||
{:ok, %{
|
||||
vendor: "cisco",
|
||||
product_line: "ios-xe",
|
||||
version: data["latestVersion"],
|
||||
download_url: data["downloadUrl"],
|
||||
# ...
|
||||
}}
|
||||
end
|
||||
```
|
||||
|
||||
**2. Update vendor detection in LiveView:**
|
||||
|
||||
```elixir
|
||||
defp determine_vendor("Cisco Systems"), do: "cisco"
|
||||
|
||||
defp determine_product_line("Cisco Systems", model) do
|
||||
cond do
|
||||
String.contains?(model, "Catalyst") -> "ios-xe"
|
||||
String.contains?(model, "ASR") -> "ios-xr"
|
||||
true -> "ios"
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
**3. Run migration to add new firmware release record** (happens automatically via worker)
|
||||
|
||||
### Configuration-Based Approach (Future Enhancement)
|
||||
|
||||
Store vendor fetch configurations in database or config file:
|
||||
|
||||
```elixir
|
||||
# config/firmware_sources.exs
|
||||
[
|
||||
%{
|
||||
vendor: "mikrotik",
|
||||
product_line: "routeros",
|
||||
source_type: :rss,
|
||||
url: "https://cdn.mikrotik.com/routeros/latest-stable.rss",
|
||||
parser: Towerops.Devices.FirmwareParsers.MikroTikRSS
|
||||
},
|
||||
%{
|
||||
vendor: "cisco",
|
||||
product_line: "ios-xe",
|
||||
source_type: :api,
|
||||
url: "https://software.cisco.com/api/latest",
|
||||
parser: Towerops.Devices.FirmwareParsers.CiscoAPI,
|
||||
auth: :api_key
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
**1. Version Comparator Tests** (see above)
|
||||
|
||||
**2. RSS Parsing Tests:**
|
||||
|
||||
```elixir
|
||||
defmodule Towerops.Workers.FirmwareVersionFetcherWorkerTest do
|
||||
use Towerops.DataCase
|
||||
|
||||
test "parses MikroTik RSS correctly" do
|
||||
xml = """
|
||||
<?xml version="1.0"?>
|
||||
<rss version="2.0">
|
||||
<channel>
|
||||
<item>
|
||||
<title>7.14.1</title>
|
||||
<link>https://mikrotik.com/download</link>
|
||||
<pubDate>Wed, 15 Jan 2025 12:00:00 +0000</pubDate>
|
||||
</item>
|
||||
</channel>
|
||||
</rss>
|
||||
"""
|
||||
|
||||
# Test parsing logic
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
**3. Version Change Detection:**
|
||||
|
||||
```elixir
|
||||
test "detects firmware version change during discovery" do
|
||||
device = insert(:device)
|
||||
snmp_device = insert(:snmp_device, device: device, firmware_version: "7.12.1")
|
||||
|
||||
# Run discovery with new version
|
||||
# Assert DeviceFirmwareHistory record created
|
||||
# Assert PubSub broadcast sent
|
||||
end
|
||||
|
||||
test "does not log change for initial discovery" do
|
||||
device = insert(:device)
|
||||
# No existing snmp_device
|
||||
|
||||
# Run discovery
|
||||
# Assert no DeviceFirmwareHistory record
|
||||
end
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
**1. Worker Execution:**
|
||||
|
||||
```elixir
|
||||
test "FirmwareVersionFetcherWorker fetches and stores MikroTik version" do
|
||||
# Mock HTTP response
|
||||
# Execute worker
|
||||
# Assert FirmwareRelease record created/updated
|
||||
end
|
||||
```
|
||||
|
||||
**2. LiveView Display:**
|
||||
|
||||
```elixir
|
||||
test "shows firmware update indicator when newer version available" do
|
||||
firmware_release = insert(:firmware_release, vendor: "mikrotik", version: "7.14.1")
|
||||
snmp_device = insert(:snmp_device, manufacturer: "MikroTik", firmware_version: "7.12.1")
|
||||
|
||||
{:ok, view, _html} = live(conn, ~p"/devices/#{snmp_device.device_id}")
|
||||
|
||||
assert has_element?(view, "[data-test='firmware-update-indicator']")
|
||||
assert render(view) =~ "7.14.1"
|
||||
end
|
||||
```
|
||||
|
||||
## Implementation Checklist

|
||||
|
||||
## Future Enhancements
|
||||
|
||||
1. **Version History Display:**
|
||||
- Add "Firmware History" tab to device detail page
|
||||
- Show timeline of version changes with dates
|
||||
|
||||
2. **Firmware Update Notifications:**
|
||||
- Email digest of devices with available updates
|
||||
- Dashboard widget showing update summary
|
||||
|
||||
3. **Bulk Update Tracking:**
|
||||
- Mark multiple devices as "planned for update"
|
||||
- Track update completion across organization
|
||||
|
||||
4. **Multi-Vendor Support:**
|
||||
- Cisco IOS/IOS-XE (requires API or web scraping)
|
||||
- Ubiquiti UniFi (RSS or API)
|
||||
- Juniper JunOS (API)
|
||||
|
||||
5. **Release Notes Parsing:**
|
||||
- Extract changelog highlights from vendor sources
|
||||
- Display in-app without external link
|
||||
|
||||
6. **Smart Update Recommendations:**
|
||||
- Security bulletin awareness (CVE tracking)
|
||||
- Recommend updates based on severity
|
||||
- "Skip this version" for known problematic releases
|
||||
|
||||
## Security Considerations
|
||||
|
||||
1. **External HTTP Requests:**
|
||||
- RSS feeds are public, no authentication required
|
||||
- Use HTTPS for all vendor URLs
|
||||
- Set reasonable timeouts (5-10 seconds)
|
||||
- Rate limit to avoid overwhelming vendor servers
|
||||
|
||||
2. **Data Validation:**
|
||||
- Sanitize all parsed XML/JSON before storage
|
||||
- Validate version format before comparison
|
||||
- Prevent XML entity expansion attacks (XXE)
|
||||
|
||||
3. **PII/Sensitive Data:**
|
||||
- No sensitive data in firmware tracking
|
||||
- Download URLs are public vendor pages
|
||||
- Device firmware versions are operational metadata
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
1. **RSS Fetching:**
|
||||
- Daily schedule minimizes external requests
|
||||
- Async worker doesn't block web requests
|
||||
- Failed fetches retry (Oban max_attempts: 3)
|
||||
|
||||
2. **LiveView Loading:**
|
||||
- Firmware lookup is single query by vendor/product_line
|
||||
- Indexed unique constraint makes lookup fast
|
||||
- Version comparison is in-memory (no DB query)
|
||||
|
||||
3. **Version History:**
|
||||
- Indexed on `snmp_device_id + detected_at`
|
||||
- Limit queries to recent N records (default 20)
|
||||
- Cascading delete prevents orphaned records
|
||||
|
||||
## Rollout Plan
|
||||
|
||||
1. **Deploy schema migrations** (production downtime: ~5 seconds)
|
||||
2. **Deploy worker code** (no immediate execution)
|
||||
3. **Manually trigger worker** to seed initial firmware data: `Oban.insert(Towerops.Workers.FirmwareVersionFetcherWorker.new(%{}))`
|
||||
4. **Verify firmware release record** created
|
||||
5. **Monitor cron execution** daily at 2am
|
||||
6. **Enable LiveView indicator** after confirming data accuracy
|
||||
|
||||
## Monitoring & Alerts
|
||||
|
||||
1. **Worker Failures:**
|
||||
- Oban dashboard shows failed jobs
|
||||
- Email alert if worker fails 3 consecutive days
|
||||
- Log warning if RSS format changes unexpectedly
|
||||
|
||||
2. **Data Freshness:**
|
||||
- Alert if `firmware_releases.fetched_at` >48 hours old
|
||||
- Dashboard shows last successful fetch time
|
||||
|
||||
3. **Version Comparison Issues:**
|
||||
- Log warning for unparseable version strings
|
||||
- Store raw version in history for manual review
