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.
