2021-02-09	pipe: writeLocked has to return ErrWouldBlock if the pipe is full	Andrei Vagin
	PiperOrigin-RevId: 356450303
2020-11-16	Reset watchdog timer between sendfile() iterations.	Jamie Liu
	As part of this, change Task.interrupted() to not drain Task.interruptChan, and do so explicitly using new function Task.unsetInterrupted() instead. PiperOrigin-RevId: 342768365
2020-11-06	Fix infinite loop when splicing to pipes/eventfds.	Nicolas Lacasse
	Writes to pipes of size < PIPE_BUF are guaranteed to be atomic, so writes larger than that will return EAGAIN if the pipe has capacity < PIPE_BUF. Writes to eventfds will return EAGAIN if the write would cause the eventfd value to go over the max. In both such cases, calling Ready() on the FD will return true (because it is possible to write), but specific kinds of writes will in fact return EAGAIN. This CL fixes an infinite loop in splice and sendfile (VFS1 and VFS2) by forcing skipping the readiness check for the outfile in send, splice, and tee. PiperOrigin-RevId: 341102260
2020-08-28	Fix EOF handling for splice.	Dean Deng
	Also, add corresponding EOF tests for splice/sendfile. Discovered by syzkaller. PiperOrigin-RevId: 328975990
2020-08-27	Fix 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.

2020-04-13	Don't allow read/write when offset+size overflows.	Nicolas Lacasse
	PiperOrigin-RevId: 306348346
2020-04-03	Ensure EOF is handled propertly during splice.	Adin Scannell
	PiperOrigin-RevId: 304684417
2019-10-03	Don't report partialResult errors from sendfile	Andrei Vagin
	The input file descriptor is always a regular file, so sendfile can't lose any data if it will not be able to write them to the output file descriptor. Reported-by: syzbot+22d22330a35fa1c02155@syzkaller.appspotmail.com PiperOrigin-RevId: 272730357
2019-09-12	Implement splice methods for pipes and sockets.	Adin Scannell
	This also allows the tee(2) implementation to be enabled, since dup can now be properly supported via WriteTo. Note that this change necessitated some minor restructoring with the fs.FileOperations splice methods. If the *fs.File is passed through directly, then only public API methods are accessible, which will deadlock immediately since the locking is already done by fs.Splice. Instead, we pass through an abstract io.Reader or io.Writer, which elide locks and use the underlying fs.FileOperations directly. PiperOrigin-RevId: 268805207
2019-08-27	Fix sendfile(2) error code	Fabricio Voznika
	When output file is in append mode, sendfile(2) should fail with EINVAL and not EBADF. Closes #721 PiperOrigin-RevId: 265718958
2019-06-28	Fix suggestions from clang.	Nicolas Lacasse
