2021-10-07add convenient wrapper for eventfdKevin Krakauer
The same create/write/read pattern is copied around several places. It's easier to understand in a package with names and comments, and we can reuse the smart blocking code in package rawfile. PiperOrigin-RevId: 401647108
2021-03-03[op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t. Updates #214 PiperOrigin-RevId: 360701387
2021-02-24Move //pkg/gate.Gate to //pkg/sync.Jamie Liu
- Use atomic add rather than CAS in every Gate method, which is slightly faster in most cases. - Implement Close wakeup using gopark/goready to avoid channel allocation. New benchmarks: name old time/op new time/op delta GateEnterLeave-12 16.7ns ± 1% 10.3ns ± 1% -38.44% (p=0.000 n=9+8) GateClose-12 50.2ns ± 8% 42.4ns ± 6% -15.44% (p=0.000 n=10+10) GateEnterLeaveAsyncClose-12 972ns ± 2% 640ns ± 7% -34.15% (p=0.000 n=9+10) PiperOrigin-RevId: 359336344

2020-08-20Consistent precondition formattingMichael Pratt
Our "Preconditions:" blocks are very useful to determine the input invariants, but they are bit inconsistent throughout the codebase, which makes them harder to read (particularly cases with 5+ conditions in a single paragraph). I've reformatted all of the cases to fit in simple rules: 1. Cases with a single condition are placed on a single line. 2. Cases with multiple conditions are placed in a bulleted list. This format has been added to the style guide. I've also mentioned "Postconditions:", though those are much less frequently used, and all uses already match this style. PiperOrigin-RevId: 327687465

2020-01-09New 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
2019-09-12Remove go_test from go_stateify and go_marshalMichael Pratt
They are no-ops, so the standard rule works fine. PiperOrigin-RevId: 268776264
2019-07-30Change syscall.POLL to syscall.PPOLL.Haibo Xu

This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

2018-06-11Set CLOEXEC option to socketsFabricio Voznika
hostinet/socket.go: the Sentry doesn't spawn new processes, but it doesn't hurt to protect the socket from leaking. unet/unet.go: should be setting closing on exec. The FD is explicitly donated to children when needed. PiperOrigin-RevId: 200135682 Change-Id: Ia8a45ced1e00a19420c8611b12e7a8ee770f89cb
