# AWS VPN Client Patcher

Scripts for patching the AWS VPN client for Linux.

 - Removes function that disables `net.ipv4.ip_forward` when connecting.
 - Makes the SAML success page close automatically.

### Setup

To setup the build, run:

```
make init
```

This copies the DLLs that will be patched into the `origin` directory.
> Note:
> - After install the unpatched versions can be restored by running `make reset`.
> - When upgrading the AWS VPN client, delete the origin directory to clear the local copies of the patched DLLs.
> - If the origin directory is removed and the DLLs have not been reset then you must re-install the AWS VPN client.

### Build

To build patched binaries, run:

```
make
```

### Install

To install the binaries, first close any VPN client windows, then run:

```
make install
```

> Note: May need to be run as root

After install, make sure you restart the VPN service:

```
systemctl restart awsvpnclient.service
```

### Making Changes

Check out the relevant branch for your tool version.

Run:
```
make unpack
```

This creates a directory `.unpack` and disassembles the DLLs into it.

To apply the existing patches, run:

```
patch .unpack/${ASSEMBLY}.il src/${ASSEMBLY}.il.diff
```

Modify the .il files as required then run:

```
diff -u .unpack/${ASSEMBLY}.il.original .unpack/${ASSEMBLY}.il > src/${ASSEMBLY}.il.diff
```

This generates the patch that will be applied by the build process.
