2020-08-31Run syscall tests in uts namespaces.Rahat Mahmood
Some syscall tests, namely uname_test_* modify the host and domain name, which modifies the execution environment and can have unintended consequences on other tests. For example, modifying the hostname causes some networking tests to fail DNS lookups. Run all syscall tests in their own uts namespaces to isolate these changes. PiperOrigin-RevId: 329348127

2020-08-28Don't bind loopback to all IPs in an IPv6 subnetGhanan Gowripalan
An earlier change considered the loopback bound to all addresses in an assigned subnet.

2020-08-28Improve type safety for network protocol optionsGhanan Gowripalan
The existing implementation for NetworkProtocol.{Set}Option take arguments of an empty interface type which all types (implicitly) implement; any type may be passed to the functions. This change introduces marker interfaces for network protocol options that may be set or queried which network protocol option types implement to ensure that invalid types are caught at compile time. Different interfaces are used to allow the compiler to enforce read-only or set-only socket options. PiperOrigin-RevId: 328980359

2020-08-27Fix vfs2 pipe behavior when splicing to a non-pipe.Dean Deng
Fixes *.sh Java runtime tests, where splice()-ing from a pipe to /dev/zero would not actually empty the pipe. There was no guarantee that the data would actually be consumed on a splice operation unless the output file's implementation of Write/PWrite actually called VFSPipeFD.CopyIn. Now, whatever bytes are "written" are consumed regardless of whether CopyIn is called or not. Furthermore, the number of bytes in the IOSequence for reads is now capped at the amount of data actually available. Before, splicing to /dev/zero would always return the requested splice size without taking the actual available data into account. This change also refactors the case where an input file is spliced into an output pipe so that it follows a similar pattern, which is arguably cleaner anyway. Updates #3576.
