Subtract 4 from the received packet length - the buffer contains the
CRC, which we shouldn't pass up.
Ensure we allocate receive buffers of a size corresponding to the
rounded-up size we tell the hardware - the hardware was overrunning the
allocation by a couple of bytes.
- Changed mutexes to platform mutexes
- Removed not needed null check from delete
- Changed nsapi_dns_call_in_set() to use call_in_callback_cb_t and
added prototype to header
- 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.
Implementation of unified EMAC driver for Renesas mbed boards
Based on the driver so far, Renesas implemented the emac driver for GR-PEACH and VK-RZ/A1H.
The mainly changes is below.
- Add the connection part with LWIP according to the unified emac specification.
- Add three new multicast functions(add, remove, set_all).
The Greentea test netsocket and emac test passed.
Just checking "does the chip have an EMAC" doesn't work - there are
targets using those chips which do not have an Ethernet connector and
don't provide the necessary surrounding infrastructure (eg DISCO_F429ZI,
not providing the board emac config call, and HEXIWEAR not providing PHY
info).
Make the targets that actually do want EMAC define their own local
Freescale_EMAC and STM_EMAC labels, and move the drivers into
the corresponding TARGET_ directories, removing the #ifdefs.
Checking DEVICE_EMAC is problematic - particularly for the Odin W2 where
apps have been shutting this off to disable the Wi-fi interface.
Make drivers check a locally-relevant flag instead, pending new
thoughts on how to achieve application/test-relevant flagging for
XXX:get_default_instance() being provided by a system.
However that is achieved, drivers do require a flag set purely by the
target - they mustn't be tripped up by an add-on module providing itself
as the system's default EMAC.
Make Nanostack an OnboardNetworkInterface, implementing
add_ethernet_interface so it can use EMAC drivers.
Can now be used via EthernetInterface, and be the system's default
network stack.
Legacy support for NanostackEthernetInterface retained. Some
restructuring of mesh interface code to fit into the
OnboardNetworkStack:::Interface system.
As we've introduced virtual inheritance to support EMACInterface, we can
no longer use C-style casts or static_cast to downcast from
NetworkInterface to more specific types. RTTI is disabled in the
toolchains, so dynamic_cast is unavailables.
Add virtual downcast methods to permit conversions to the 6 derived
classes. Probably only needed for EMACInterface, WiFiInterface and
EthInterface, but handles the set.
This has been superceded by CellularBase. Name change occurred late
in review of https://github.com/ARMmbed/mbed-os/pull/4119 and
original unused CellularInterface was left behind.
Rather than let "EthernetInterface" be the base EMAC NetworkInterface,
insert an "EMACInterface" class.
EthernetInterface then derives from EMACInterface and EthInterface.
A Wi-Fi driver can derive from EMACInterface and WiFiInterface - this
will be more logical than deriving from EthernetInterface and
WiFiInterface.
This does mean adding a couple of virtual inheritances to avoid
duplicate NetworkInterfaces:
NetworkInterface

virtual / \ virtual

EMACInterface WiFiInterface

Initial work by Bartek Szatkowski in https://github.com/ARMmbed/mbed-os/pull/4079,
reworked following review of https://github.com/ARMmbed/mbed-os/pull/5202 to
transform the entire system into C++, retaining the basic functionality.
Bartek's summary:
* Porting ethernet to EMAC
* Updating EMAC to enable multiple interfaces
* Untangling networking classes, making the abstractions a bit clearer to follow, etc
* General refactoring
* Removal of DEVICE_EMAC flag and introducing DEVICE_ETH and DEVICE_WIFI
Revisions since initial branch:
* Remove lwip depencies
* Correct doxygen warnings
* Remove emac_api.h, replace with C++ EMAC abstract class.
* Create OnboardNetworkInterface, and LWIP implementation.
* Mappings since #4079
lwip-interface/nsapi_stack_lwip.c -> LWIPStack.cpp
lwip-interface/ipstack_lwip.c -> LWIPInterface.cpp
netsocket/mbed_ipstack.h -> OnboardNetworkStack.h
hal/emac_api.h -> EMAC.h
* Reinstate use of EthInterface abstraction
* Correct and clarify HW address EMAC ops
* Restore MBED_MAC_ADDR implementation
* Integrate PPP support with LWIP::Interface.
* Convert K64F lwIP driver to K64F_EMAC.
To do:
* Convert emac_stack_mem.h to follow this pattern.
* Figure out DEVICE_ETH/EMAC
* Update all drivers to use EMAC
