Minor tweaks to fix ARM C 5 compatibility.
Pushing "ns_list.h" include to first makes sure "ns_types.h" is included
first, meaning it gets to define `__STDC_LIMIT_MACROS` before the first
include of <stdint.h>, which ensures that UINT8_MAX etc are defined.
Added Multihoming feature to LWIP (ability to use more than one network interfaces) for increasing networking reliability.
This involves:
LWIP interface
LWIP IP routing
DNS storage
Sockets (bind to interface name possibility)
possibility to add non default network interface
cellular middleware modifications if cellular connection is used
Allow more than one callback to be register to NetworkInterfaces.
This introduces new APIs:
void NetworkInterface::add_event_listener(...);
void NetworkInterface::remove_event_listener(...);
Which internally calls interfaces attach() functions.
- Serialized the sending of multiple async DNS queries since limits on event
message box sizes
- Added timer function that supervises the total time used to make DNS query
and triggers socket timeouts
- Changed nsapi_error_t to new nsapi_value_or_error_t on interface headers
- Corrected wording of gethostbyname_async return values
- Clarified .json options
- Added a new data type for socket callback that can be used from interrupts
- Corrected variable limits to use INT32_MAX etc. defines
- Changed mallocs to new
- Optimized variable sizes on DNS_QUERY definition
- Changed call_in/call methods of the stack to callback provided by the stack
- Specified what are limitations for operations that are made in callback
- Added pure virtual class DNS that defines DNS operations
- Added cancel operation and unique ID to DNS request used in cancel
- Added DNS configuration options to netsocket/mbed_lib.json for retries,
response wait time and cache size
- Changed host name to use dynamic memory in DNS query list and cache,
set maximum length for the name to 255 bytes.
- Added mutex to asynchronous DNS
- Reworked retries: there is now total retry count and a server specific count
- Ignores invalid incoming UDP socket messages (DNS header is not valid), and retries DNS query
- Reworked DNS module asynchronous operation functions
- Corrected other review issues (nothrow new, missing free, missing mutex unlock etc.)
- Added non-blocking DNS interface to network interface and
network stack.
- Added caching of DNS replies.
- Added a network stack function to get DNS addresses from stack.
- Added call and call_in hooks to onboard network stack to
allow calling functions from onboard stack context.
- Added support to call and call_in functions to LWIP and
Nanostack.
- Disabled LWIP DNS translator with the exception of DNS
address storage used in DNS address get.
nsapi_error_t - enum of errors or 0 for NSAPI_ERROR_OK
nsapi_size_t - unsigned size of data that could be sent
nsapi_size_or_error_t - either a non-negative size or negative error
