To avoid complications with unexpected IP versions, the wanted
IP version was added as an extra argument to DNS query functions
(defaults to NSAPI_IPv4).
Internal API changes:
m nsapi_dns_query
m nsapi_dns_query_multiple
Interestingly, though multiple questions can be encoded in a single
DNS packet, few, if any, nameservers respect any but the first
question. This makes support for coelescing DNS queries useless.
Internal API changes:
+ nsapi_dns_query_multiple
Note, dns_query_multiple takes a buffer of nsapi_addr_t to fill. This is
less dynamic than the linked-list method used in linux's gethostbyname,
but is easier to manage and more constrained.
Internal API changes:
dnsQuery -> nsapi_dns_query
Additionally restructured query code to emit/parse network structures
in stream form to hopefully document the underlying structure more
explicitly.
Fixes issue #2399 by optionally returning a SocketAddress from
TCPServer::accept().
This entails changes to underlying NetworkStack and nsapi. This
commit deals only with lwip and higher level APIs; other users of
NetworkStack and nsapi may be affected. Currently lwip is the only
in-tree user of nsapi.
Currently this uses the same mechanism used by the rtos to conditionally
include the network-socket API. Perhaps this should be builtin to the
config system?
Note: this does require that the bug-compatible inclusion of mbed.h
be removed to avoid include-order issues.
