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.
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.
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.
Support intended for DNS servers provided by DHCP requests.
Provides proper integration with DHCP through lwip
- Separated overloads based on language - Removed NSAPI_C_LINKAGE definition
@0xc0170, thoughts on the rewrite of nsapi_dns.h? It should be cleaner now, with clear language separation. |
LGTM 👍 Do we have any tests for DNS? If not could we add at least a smoke test? |
There is currently a simple test on DNS inside the nist_internet_time_service test: https://github.com/ARMmbed/mbed-os/blob/master/features/net/FEATURE_IPV4/TESTS/mbedmicro-net/nist_internet_time_service/main.cpp#L32 I've also been testing locally with mbed-os-example-client on WiFi. |

This should resolve several long running issues related to local DNS servers, such as #2369 and https://github.com/ARMmbed/mbed-os-morpheus/issues/462.
