2020-03-16	fdtable: don't try to zap fdtable entry if close is called for non-existing fd	Andrei Vagin
	FDTable.setAll is used to zap entries, but it grows the table up to a specified fd. Reported-by: syzbot+9e281b0750d2d4caa190@syzkaller.appspotmail.com PiperOrigin-RevId: 301280000
2020-03-13	Add remaining procfs files	Fabricio Voznika
	Closes #1195 PiperOrigin-RevId: 300867055
2020-03-13	Panic if file in FDTable has been destroyed	Fabricio Voznika
	This will give more information about the file to identify where possibly the extra DecRef() would be. PiperOrigin-RevId: 300855874
2020-02-25	Port most syscalls to VFS2.	Jamie Liu
	pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2. mount and umount2 aren't ported out of temporary laziness. access and faccessat need additional FSImpl methods to implement properly, but are stubbed to prevent googletest from CHECK-failing. Other syscalls require additional plumbing. Updates #1623 PiperOrigin-RevId: 297188448
2020-01-28	Changes missing in last submit	Fabricio Voznika
	Updates #1487 Updates #1623 PiperOrigin-RevId: 292040835
2020-01-28	Add vfs.FileDescription to FD table	Fabricio Voznika
	FD table now holds both VFS1 and VFS2 types and uses the correct one based on what's set. Parts of this CL are just initial changes (e.g. sys_read.go, runsc/main.go) to serve as a template for the remaining changes. Updates #1487 Updates #1623 PiperOrigin-RevId: 292023223
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
2020-01-27	Fix licenses.	Adin Scannell
	The preferred Copyright holder is "The gVisor Authors". PiperOrigin-RevId: 291786657
2020-01-09	New sync package.	Ian Gudger
	* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387
2019-10-23	Keep minimal available fd to accelerate fd allocation	DarcySail
	Use fd.next to store the iteration start position, which can be used to accelerate allocating new FDs. And adding the corresponding gtest benchmark to measure performance. @tanjianfeng COPYBARA_INTEGRATE_REVIEW=https://github.com/google/gvisor/pull/758 from DarcySail:master 96685ec7886dfe1a64988406831d3bc002b438cc PiperOrigin-RevId: 276351250
2019-07-17	Fix race in FDTable.GetFDs().	Bhasker Hariharan

2019-07-02	Remove map from fd_map, change to fd_table.	Adin Scannell
	This renames FDMap to FDTable and drops the kernel.FD type, which had an entire package to itself and didn't serve much use (it was freely cast between types, and served as more of an annoyance than providing any protection.) Based on BenchmarkFDLookupAndDecRef-12, we can expect 5-10 ns per lookup operation, and 10-15 ns per concurrent lookup operation of savings. This also fixes two tangential usage issues with the FDMap. Namely, non-atomic use of NewFDFrom and associated calls to Remove (that are both racy and fail to drop the reference on the underlying file.) PiperOrigin-RevId: 256285890
