2020-07-23[vfs2][gofer] Fix update attributes race condition.Ayush Ranjan
We were getting the file attributes before locking the metadataMu which was causing stale updates to the file attributes. Fixes OpenTest_AppendConcurrentWrite. Updates #2923 PiperOrigin-RevId: 322804438

2020-07-22make connect(2) fail when dest is unreachableKevin Krakauer
Previously, ICMP destination unreachable datagrams were ignored by TCP endpoints. This caused connect to hang when an intermediate router couldn't find a route to the host. This manifested as a Kokoro error when Docker IPv6 was enabled. The Ruby image test would try to install the sinatra gem and hang indefinitely attempting to use an IPv6 address. Fixes #3079.
2020-07-22iptables: don't NAT existing connectionsKevin Krakauer
Fixes a NAT bug that manifested as: - A SYN was sent from gVisor to another host, unaffected by iptables. - The corresponding SYN/ACK was NATted by a PREROUTING REDIRECT rule despite being part of the existing connection. - The socket that sent the SYN never received the SYN/ACK and thus a connection could not be established. We handle this (as Linux does) by tracking all connections, inserting a no-op conntrack rule for new connections with no rules of their own. Needed for istio support (#170).

2020-07-22iptables: replace maps with arraysKevin Krakauer
For iptables users, Check() is a hot path called for every packet one or more times. Let's avoid a bunch of map lookups. PiperOrigin-RevId: 322678699
