2021-01-26Move SO_SNDBUF to socketops.Nayana Bidari
This CL moves {S,G}etsockopt of SO_SNDBUF from all endpoints to socketops. For unix sockets, we do not support setting of this option. PiperOrigin-RevId: 353871484

2021-01-26Do not generate extraneous IN_CLOSE inotify events.Dean Deng

2021-01-25Adjust included data size on icmp errorsJulian Elischer
The RFC for icmpv6 specifies that an errant packet should be included in the returned ICMP packet, and that it should include up to the amount needed to fill the minimum MTU (1280 bytes) if possible. The current code included the Link header in that calculation but the RFC is referring to the IP MTU not the link MTU. Some conformance tests check this and report an error agains the stack for this. The full header length shoudl however continue to be used when allocating header space. Make the same change for IPv4 for consistency. Add a test for icmp payload sizing. Test that the included data in an ICMP error packet conforms to the requirements of RFC 972, RFC 4443 section 2.4 and RFC 1812 Section 4.3.2.3. Fixes #5311 PiperOrigin-RevId: 353790203

2021-01-25Add per endpoint ARP statisticsArthur Sfez
The ARP stat NetworkUnreachable was removed, and was replaced by InterfaceHasNoLocalAddress. No stats are recorded when dealing with an missing endpoint (ErrNotConnected) (because if there is no endpoint, there is no valid per-endpoint stats). PiperOrigin-RevId: 353759462
