2020-04-13Add Sniffer.Drain() draining socket receive buffergVisor bot
Add Sniffer.Drain() which drains the socket's receive buffer by temporarily setting the socket to non-blocking, and receiving in a loop until EINTR, EWOULDBLOCK or EAGAIN. This method should be used when long periods of time elapses without receiving on the socket, because uninteresting packets may have piled up in the receive buffer, filling it up and causing packets critical to test operation to be dropped.

2020-04-13Remove unnecessary threadsTamir Duberstein
The work being done in these threads is not asynchronous with respect to the test; that is, it is equivalent to issue non-blocking `connect` calls serially, since the work is done asynchronously with respect to the caller. Futhermore, this test was added to test closing a listener with completed but not delivered connections, which never required threading in the first place. PiperOrigin-RevId: 306339486

2020-04-13Port socket-related syscalls to VFS2.Dean Deng
Note that most kinds of sockets are not yet supported in VFS2 (only Unix sockets are partially supported at the moment), so these syscalls will still generally fail. Enabling them allows us to begin running socket tests for VFS2 as more features are ported over. Updates #1476, #1478, #1484, #1485. PiperOrigin-RevId: 306292294

2020-04-10Port extended attributes to VFS2.Dean Deng
As in VFS1, we only support the user.* namespace. Plumbing is added to tmpfs and goferfs. Note that because of the slightly different order of checks between VFS2 and Linux, one of the xattr tests needs to be relaxed slightly. Fixes #2363. PiperOrigin-RevId: 305985121

Continues the modifications in cl/272963663. This prevents non-syscall errors from being propogated to kernel/task_syscall.go:ExtractErrno(), which causes a sentry panic. PiperOrigin-RevId: 305913127

2020-04-10Remove TODO from kernel.StracerFabricio Voznika
The dependency strace=>kernel grew over time. strace also depends on task's FD table and FSContext. It could be fixed with some interfaces the other way, but then we're trading an interface for another, and kernel.Stracer is likely cleaner. Closes #155 PiperOrigin-RevId: 305909678
