1This is the memory safety proof for DHCPProcessEndPoint function, which is the
2function that triggers the DHCP protocol.

4The main stubs in this proof deal with buffer management, which assume
5that the buffer is large enough to accomodate a DHCP message plus a
6few additional bytes for options (which is the last, variable-sized
7field in a DHCP message). We have abstracted away sockets, concurrency
8and third-party code. For more details, please check the comments on
9the harness file.

11This proof is a work-in-progress. Proof assumptions are described in
12the harness. The proof also assumes the following functions are
13memory safe and have no side effects relevant to the memory safety of
14this function:

16* FreeRTOS_sendto
17* FreeRTOS_setsockopt
18* FreeRTOS_socket
19* ulRand
20* vARPSendGratuitous
21* vApplicationIPNetworkEventHook
22* vLoggingPrintf
23* vPortEnterCritical
24* vPortExitCritical
25* vReleaseNetworkBufferAndDescriptor
26* vSocketBind
27* vSocketClose
