2021-05-18	Prevent infinite loops from being optimized away.	gVisor bot
	https://github.com/llvm/llvm-project/commit/6c3129549374c0e81e28fd0a21e96f8087b63a78 adds "mustprogress" to loops, which causes empty, side-effect free loops to be optimized away. These loops are intentionally infinite for purposes of testing, so add asm statements that prevent them from being removed. PiperOrigin-RevId: 374546142
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
2020-10-16	Use POSIX interval timers in flock test.	Dean Deng
	ualarm(2) is obsolete. Move IntervalTimer into a test util, where it can be used by flock tests. These tests were flaky with TSAN, probably because it slowed the tests down enough that the alarm was expiring before flock() was called. Use an interval timer so that even if we miss the first alarm (or more), flock() is still guaranteed to be interrupted. PiperOrigin-RevId: 337578751
2020-02-19	Add basic microbenchmarks.	Adin Scannell

2020-02-04	timer_create(2) should return 0 on success	Michael Pratt
	The timer ID is copied out to the argument. Fixes #1738 PiperOrigin-RevId: 293210801
2019-09-16	Migrate from gflags to absl flags	Michael Pratt
	absl flags are more modern and we can easily depend on them directly. The repo now successfully builds with --incompatible_load_cc_rules_from_bzl. PiperOrigin-RevId: 269387081

Manual fixup of "Google Inc" references. 3. Add AUTHORS file. Authors may request to be added to this file. 4. Point netstack AUTHORS to gVisor AUTHORS. Drop CONTRIBUTORS. Fixes #209 PiperOrigin-RevId: 245823212 Change-Id: I64530b24ad021a7d683137459cafc510f5ee1de9
2019-01-11	Clean up some uses of fork() in tests.	Jamie Liu
	- Fix a few cases where async-signal-unsafe code is executed in a forked process pre-execve. - Ensure that the return value of fork() is always checked. PiperOrigin-RevId: 228949310 Change-Id: I3096cb7d7394b8d9ab81b0e0245f2060713ef589
