We should try and make it more non deterministic.
Suggested change
| pxNetworkEndPoints->pxNext = ( NetworkEndPoint_t * ) malloc( sizeof( NetworkEndPoint_t ) ); | |
| __CPROVER_assume( pxNetworkEndPoints->pxNext != NULL ); | |
| if( nondet_bool() ) | |
| { | |
| pxNetworkEndPoints->pxNext = ( NetworkEndPoint_t * ) malloc( sizeof( NetworkEndPoint_t ) ); | |
| __CPROVER_assume( pxNetworkEndPoints->pxNext != NULL ); | |
| } | |
| else | |
| { | |
| pxNetworkEndPoints->pxNext = NULL; | |

Here similarly we should do this.
| __CPROVER_assume( pxSocket != FREERTOS_INVALID_SOCKET ); | ||

| pxSocket->pxUserWakeCallback = safeMalloc( sizeof( SocketWakeupCallback_t ) ); | ||
| pxSocket->pxUserWakeCallback = &SocketWakeupCallback_Stub; |
