50-50: Consider security implications of logging the full IV.While logging the full IV can help with debugging, it may expose sensitive information used in encryption. Consider:
- Logging only when debugging is enabled
- Masking part of the IV in logs
Example implementation with debug-only logging:
- echo "iv=$IV" >>$SSLINPUT + if [[ "${DEBUG:-0}" == "1" ]]; then + echo "iv=$IV" >>$SSLINPUT + else + echo "iv=$IV" | sed 's/\(.\{4\}\).*\(.\{4\}\)/\1****\2/' >>$SSLINPUT + fi

Security concern: IV generation method may weaken encryption.
The current IV generation method using MAC address with fixed prefix/suffix ("12" and "34") has several security implications:
- MAC addresses are publicly visible and can be spoofed
- Fixed prefix/suffix reduces entropy
- Predictable IVs can weaken the encryption of sensitive data (USERNAME and PASSWORD)
Consider using a cryptographically secure random number generator instead:
- IV="12$(cat $SYSTEM/$PORT/address | sed 's/://g')34"
+ IV="$(openssl rand -hex 16)"📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

38-39: Consider caching network driver information.The network driver information is fetched every time the script runs. Consider caching this information to improve performance, especially since network configurations don't change frequently during runtime.
Example implementation:
-// get network drivers -$driver = DockerUtil::driver(); +// get network drivers with caching +$driver = DockerUtil::getCachedDriver(); // In DockerUtil class: +private static $driverCache = null; + +public static function getCachedDriver() { + if (self::$driverCache === null) { + self::$driverCache = self::driver(); + } + return self::$driverCache; +}Also applies to: 298-298
1148-1152: Add error handling for network driver retrieval.The
driver()method should include error handling for cases where Docker daemon is not responsive or network commands fail.Example implementation:
public static function driver() { + try { $list = []; foreach (static::docker("network ls --format='{{.Name}}={{.Driver}}'",true) as $network) { [$net,$driver] = array_pad(explode('=',$network),2,''); $list[$net] = $driver; } return $list; + } catch (Exception $e) { + error_log("Failed to retrieve network drivers: " . $e->getMessage()); + return []; + } }

38-39: LGTM! Network driver initialization looks good.The addition of the global
$drivervariable with proper initialization usingDockerUtil::driver()is well-placed and appropriately commented.
298-298: LGTM! Consistent global variable declaration.The addition of
$driverto the global declaration ingetAllInfomethod is consistent with its usage within the method for network mode checks.

52-55: Consider rate limiting locale checks for better performance.While the locale change detection works correctly, checking for locale changes in every iteration of a 3-second loop might be unnecessary. Consider implementing a less frequent check or using an event-driven approach.
Here's a suggested implementation using a time-based check:
+$last_locale_check = 0; +$locale_check_interval = 60; // Check every minute while (true) { extract(parse_plugin_cfg('dynamix',true)); - if (_var($display,'locale') != $locale_init) { + $current_time = time(); + if ($current_time - $last_locale_check >= $locale_check_interval) { + $last_locale_check = $current_time; + if (_var($display,'locale') != $locale_init) { $locale_init = _var($display,'locale'); update_translation($locale_init); + } }

25-26: LGTM! Clean implementation of locale tracking.The initialization of
$locale_initis well-placed and follows good practices.
