The User has all rights and obligations granted by grsecurity's software license, version 2 of the GNU GPL. These rights and obligations are listed at

Notwithstanding these rights and obligations, the User acknowledges that redistribution of the provided stable patches or changelogs outside of the explicit obligations under the GPL to User's customers will result in termination of access to future updates of grsecurity stable patches and changelogs.

Works Made For Hire

No work performed in the process of grsecurity stable patch maintenance or changes made to the grsecurity patches as part of a support agreement shall be considered "works made for hire". Unless a specific arrangement has been put forth otherwise by the Company, the Company retains all Intellectual Property rights and will publish these changes under the GPL to all customers.

Governing Law

This Agreement shall be governed by and construed in accordance with the laws of Pennsylvania without regard to the conflicts of laws provisions thereof. Exclusive jurisdiction and venue for any action arising under this Agreement is in the federal and state courts having jurisdiction over The Company's principal office, and both parties hereby consent to such jurisdiction and venue for this purpose.


While the Company aims only to terminate access to the stable patches in the event of willful violation of the terms in this agreement, we reserve the right to revoke access to the stable patches and changelogs at any time for any reason. In the event of termination, the Company will at its own discretion refund payment for any remaining pre-paid period.

Waiver of Liability
