2021-08-13	[syserror] Remove pkg syserror.	Zach Koopmans
	Removes package syserror and moves still relevant code to either linuxerr or to syserr (to be later removed). Internal errors are converted from random types to *errors.Error types used in linuxerr. Internal errors are in linuxerr/internal.go. PiperOrigin-RevId: 390724202
2021-06-30	[syserror] Update syserror to linuxerr for EACCES, EBADF, and EPERM.	Zach Koopmans
	Update all instances of the above errors to the faster linuxerr implementation. With the temporary linuxerr.Equals(), no logical changes are made. PiperOrigin-RevId: 382306655
2021-06-22	[syserror] Add conversions to linuxerr with temporary Equals method.	Zach Koopmans
	Add Equals method to compare syserror and unix.Errno errors to linuxerr errors. This will facilitate removal of syserror definitions in a followup, and finding needed conversions from unix.Errno to linuxerr. PiperOrigin-RevId: 380909667
2020-01-28	fs/splice: don't report partial errors for special files	Andrei Vagin
	Special files can have additional requirements for granularity. For example, read from eventfd returns EINVAL if a size is less 8 bytes. Reported-by: syzbot+3905f5493bec08eb7b02@syzkaller.appspotmail.com PiperOrigin-RevId: 292002926
2020-01-27	Update package locations.	Adin Scannell
	Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
2020-01-07	fs/splice: don't report a partialResult error if there is no data loss	Andrei Vagin
	PiperOrigin-RevId: 288642552
2019-09-30	splice: try another fallback option only if the previous one isn't supported	Andrei Vagin
	Reported-by: syzbot+bb5ed342be51d39b0cbb@syzkaller.appspotmail.com PiperOrigin-RevId: 272110815
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
2019-06-24	fs: synchronize concurrent writes into files with O_APPEND	Andrei Vagin
	For files with O_APPEND, a file write operation gets a file size and uses it as offset to call an inode write operation. This means that all other operations which can change a file size should be blocked while the write operation doesn't complete. PiperOrigin-RevId: 254873771
2019-06-13	Update canonical repository.	Adin Scannell
	This can be merged after: https://github.com/google/gvisor-website/pull/77 or https://github.com/google/gvisor-website/pull/78 PiperOrigin-RevId: 253132620
2019-05-21	Add basic plumbing for splice and stub implementation.	Adin Scannell
	This does not actually implement an efficient splice or sendfile. Rather, it adds a generic plumbing to the file internals so that this can be added. All file implementations use the stub fileutil.NoSplice implementation, which causes sendfile and splice to fall back to an internal copy. A basic splice system call interface is added, along with a test. PiperOrigin-RevId: 249335960 Change-Id: Ic5568be2af0a505c19e7aec66d5af2480ab0939b
