2019-09-19Job control: controlling TTYs and foreground process groups.Kevin Krakauer
Adresses a deadlock with the rolled back change: https://github.com/google/gvisor/commit/b6a5b950d28e0b474fdad160b88bc15314cf9259 Creating a session from an orphaned process group was causing a lock to be acquired twice by a single goroutine. This behavior is addressed, and a test (OrphanRegression) has been added to pty.cc. Implemented the following ioctls: - TIOCSCTTY - set controlling TTY - TIOCNOTTY - remove controlling tty, maybe signal some other processes - TIOCGPGRP - get foreground process group. Also enables tcgetpgrp(). - TIOCSPGRP - set foreground process group. Also enabled tcsetpgrp(). Next steps are to actually turn terminal-generated control characters (e.g. C^c) into signals to the proper process groups, and to send SIGTTOU and SIGTTIN when appropriate.

2019-09-19Place the host UDS mounting behind --fsgofer-host-uds-allowed.Robert Tonic
This commit allows the use of the `--fsgofer-host-uds-allowed` flag to enable mounting sockets and add the appropriate seccomp filters.
2019-09-19Accelerate byte lookup in string with `bytealg/indexbyte`Hang Su
`bytealg/indexbyte` will use AVX or SSE instruction set, if possible, which could accelerate `CopyStringIn` function by 28%. In worst case(CPU doesn't support SSE), `bytealg/indexbyte` will degenerate to traversal lookup. When dealing with short strings, `bytealg/indexbyte` has the same performance level as before.

2019-09-18Signalfd supportAdin Scannell
Note that the exact semantics for these signalfds are slightly different from Linux. These signalfds are bound to the process at creation time. Reads, polls, etc. are all associated with signals directed at that task. In Linux, all signalfd operations are associated with current, regardless of where the signalfd originated. In practice, this should not be an issue given how signalfds are used. In order to fix this however, we will need to plumb the context through all the event APIs. This gets complicated really quickly, because the waiter APIs are all netstack-specific, and not generally exposed to the context. Probably not worthwhile fixing immediately.

2019-09-12Implement 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
