Secure software update in a wireless mesh radio network using peer-to-peer file sharing
Systems, methods and computer software are disclosed for performing a secure software update in a mesh network. In one embodiment, a method is disclosed, comprising: receiving, at each node of a network, a notification from a coordinating server, wherein each node of the network is listening for an image available notification; receiving, at a first node of the network, the image available notification; downloading and installing a software update image by the first node of the network; broadcasting, at the first node of the network, the image available notification to other peer nodes of the first node of the network; and downloading and installing the software update image from the first node of the network by at least one other peer node of the network.
1. A method of performing a secure software update in a mesh network, the method comprising:
downloading and installing a software update image at a first node of a network;
sending a NODE ARMED response by the first node of the network when the software update image has successfully been installed;
downloading and installing the software update image from the first node of the network by at least one other peer node of the mesh network;
determining an error condition has occurred based on performing an audit comparing a number of ACKs received from other peer nodes of the mesh network and a number of NODE ARMED messages received; and
performing a rollback operation in response to the error condition.
2. The method of claim 1 wherein the determining an error condition has occurred comprises the second node of the network not sending a NODE ARMED response.
3. The method of claim 2 wherein the determining an error condition has occurred comprises the second node of the network not sending a NODE ARMED response after a predetermined period of time has been reached.
4. The method of claim 1 wherein the determining an error condition has occurred comprises determining the system did not reboot after the update.
5. The method of claim 1 wherein all nodes of the network are at a same software version after the rollback operation has been performed.
6. The method of claim 1 wherein an update starts by broadcasting a control packet to all nodes.
7. A system for performing a secure software update in a network, the system comprising:
a network having a plurality of nodes in communication with one another;
a first node of the network configured to download and install a software update image at a first node of the network;
a second node of the network configured to download and install the software update image from the first node of the network;
the plurality of nodes of the network configured to send a NODE ARMED response when the software update image has successfully been installed;
the system configured to determine that an error condition has occurred based on performing an audit comparing a number of ACKs received from other peer nodes of the mesh network and a number of NODE ARMED messages received; and
the system configured to perform a rollback operation in response to the error condition.
8. The system of claim 7 wherein the error condition occurs when the second node of the network has not sent a NODE ARMED response.
9. The system of claim 8 wherein the error condition occurs when the second node of the network has not sent a NODE ARMED response after a predetermined period of time has been reached.
10. The system of claim 7 wherein the error condition occurs when the system does not reboot after the update.
11. The system of claim 7 wherein all nodes of the network are at a same software version after the rollback operation has been performed.
12. The system of claim 7 wherein an update starts when a control packet is broadcast to all nodes.
13. A non-transitory computer-readable medium containing instructions for performing a secure software update in a mesh network, when executed, cause a system to perform steps comprising:
downloading and installing a software update image at a first node of a network;
sending a NODE ARMED response by the first node of the network when the software update image has successfully been installed;
downloading and installing the software update image from the first node of the network by at least one other peer node of the mesh network;
determining an error condition has occurred based on performing an audit comparing a number of ACKs received from other peer nodes of the mesh network and a number of NODE ARMED messages received; and
performing a rollback operation in response to the error condition.
14. The computer-readable medium of claim 13 wherein the determining an error condition has occurred comprises the second node of the network not sending a NODE ARMED response.
15. The computer-readable medium of claim 14 wherein the instructions for determining an error condition has occurred comprises instructions for when the second node of the network not sending a NODE ARMED response after a predetermined period of time has been reached.
16. The computer-readable medium of claim 13 wherein the instructions for determining an error condition has occurred comprises instructions for determining the system did not reboot after the update.
17. The computer-readable medium of claim 13 further comprising instructions wherein all nodes of the network are at a same software version after the rollback operation has been performed.
18. The computer-readable medium of claim 13 further comprising instructions wherein an update starts by broadcasting a control packet to all nodes.
