Firefly mediaserver

To improve device security, Android 7.0 breaks up the monolithicmediaserver process into multiple processes with permissions andcapabilities restricted to only those required by each process. These changesmitigate media framework security vulnerabilities by:Splitting AV pipeline components into app-specific sandboxed processes.Enabling updatable media components (extractors, codecs, etc.).These changes also improve security for end users by significantly reducingthe severity of most media-related security vulnerabilities, keeping end userdevices and data safe.OEMs and SoC vendors need to update their HAL and framework changes to makethem compatible with the new architecture. Specifically, because vendor-providedAndroid code often assumes everything runs in the same process, vendors mustupdate their code to pass around native handles (native_handle)that have meaning across processes. For a reference implementation of changesrelated to media hardening, refer to frameworks/av andframeworks/native.Architectural changesPrevious versions of Android used a single, monolithicmediaserver process with great many permissions (camera access,audio access, video driver access, file access, network access, etc.). Android7.0 splits the mediaserver process into several new processes thateach require a much smaller set of permissions:Figure 1. Architecture changes formediaserver hardeningThis new architecture ensures that even if a process is compromised,malicious code does not have access to the full set of permissions previouslyheld by mediaserver. Processes are restricted by SElinux and seccomp policies.Note: Because of vendor dependencies, some codecsstill run in the mediaserver and consequently grantmediaserver more permissions than necessary. Specifically, WidevineClassic continues to run in the mediaserver for Android 7.0.MediaServer changesIn Android 7.0, the mediaserver process exists for drivingplayback and recording, e.g. passing and synchronizing buffers betweencomponents and processes. Processes

Communicate through the standard Bindermechanism.In a standard local file playback session, the app passes a filedescriptor (FD) to mediaserver (usually via the MediaPlayer JavaAPI), and the mediaserver:Wraps the FD into a Binder DataSource object that is passed to the extractorprocess, which uses it to read from the file using Binder IPC. (Themediaextractor doesn't get the FD but instead makes Binder calls back to themediaserver to get the data.)Examines the file, creates the appropriate extractor for the file type(e.g. MP3Extractor, or MPEG4Extractor), and returns a Binder interface for theextractor to the mediaserver process.Makes Binder IPC calls to the extractor to determine the type of data in thefile (e.g. MP3 or H.264 data).Calls into the mediacodec process to create codecs of therequired type; receives Binder interfaces for these codecs.Makes repeated Binder IPC calls to the extractor to read encoded samples,uses the Binder IPC to send encoded data to the mediacodec processfor decoding, and receives decoded data.In some use cases, no codec is involved (such as an offloaded playback whereencoded data is sent directly to the output device), or the codec may render thedecoded data directly instead of returning a buffer of decoded data (videoplayback).MediaCodecService changesThe codec service is where encoders and decoders live. Due to vendordependencies, not all codecs live in the codec process yet. In Android 7.0:Non-secure decoders and software encoders live in the codec process.Secure decoders and hardware encoders live in the mediaserver(unchanged).An app (or mediaserver) calls the codec process to create a codec ofthe required type, then calls that

The DW Media Server replace the old cert.pem file with new file that was created in Part 1: Creating a Custom SSL Certificate. When ready, start the DW Spectrum Media Server. Windows OS Locate the Service Tray on the Windows Task Bar. Right-click on the DW Media Server icon and select Start Server (stopped). Ubuntu OS Start the DW Media Server in the Terminal program with the command:service digitalwatchdog-mediaserver startThis completes the application of the new cert.pem SSL certification file.Expired Self-Signed SSL CertificatesIf a DW Spectrum Server’s SSL Certificate (self-signed or public) has expired, the following prompt will appear:Enable (check) the “Trust this server” checkbox and select “Connect Anyway” to continue with connecting to the Server. This prompt will continue to appear each time you attempt to connect with the Server until the certificate has been renewed.Alternatively, you can disable the SSL Certificate verification setting in the DW Spectrum Mobile application, but this is not recommended as it will lower the security level of your connection.Renewing (Recreating) an Expired Self-Signed SSL CertificateA new self-signed cert.pem file can be generated and will be valid for up to one year after it has been re-created by the system.To renew (re-create) another self-signed SSL certificate for DW Spectrum: Stop the DW Spectrum Media Server. Windows OS Locate the Service Tray on the Windows Task Bar. Right-click on the DW Media Server icon and select Stop server (started). Ubuntu OS Open the Terminal program on the Linux computer. You can do this by using the Search function in the system Unity menu.Alternatively, you can simultaneously press the Ctrl+Alt+T keys on the keyboard to launch the Terminal program. The Terminal window will display.Log in as the root Administrator by using: When prompted, enter the root admin password (will not display). **NOTE: For older DW Blackjack units purchased prior to June 18, 2021, the previously utilized default Linux OS login was “admin/admin”. Next stop the DW Media Server with:service digitalwatchdog-mediaserver stop Next, locate the old self-signed certificate file labeled “cert” (cert.pem file). Systems Using Windows OS:C:\Windows\System32\config\systemprofile\AppData\Local\Digital Watchdog\Digital Watchdog Media Server\ssl Systems Using Ubuntu OS:/opt/digitalwatchdog/mediaserver/var/sslOnce located, right-click on the file and select “Delete” to remove the old self-signed certificate file. After deleting the old self-signed certificate, start the DW Spectrum Media Server. A new cert.pem file will be generated and will display in the same SSL folder where the old file was previously located.This renewed certificate will be valid for up to one (1) year following this re-creation. Windows OS Locate the Service Tray on the Windows Task Bar. Right-click on the DW Media Server icon and select Start Server (stoppe. Ubuntu OS Start the DW Media Server using the Terminal program with the command:service digitalwatchdog-mediaserver start
