2021-05-11fix pty_test error by releasing tty received from testHoward Zhang
The test Truncate set ControllingTTY without releasing it on VFS2. This leads test ReleaseTTYSignals and ReleaseTTY fail when setting ControllingTTY. Skip the test on VFS1 and native, as setting Controlling TTY when open replica only happens on VFS2. Signed-off-by: Howard Zhang <howard.zhang@arm.com>

Updates #2972 PiperOrigin-RevId: 329584905
2020-08-27Fix JobControl tests for open source.Zach Koopmans
ioctl calls with TIOCSCTTY fail if the calling process already has a controlling terminal, which occurs on a 5.4 kernel like our Ubuntu 18 CI. Thus, run tests calling ioctl TTOCSCTTY in clean subprocess. Also, while we're here, switch out non-inclusive master/slave for main/replica. PiperOrigin-RevId: 328756598

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.

2019-05-03gvisor: run bazel in a docker containerAndrei Vagin
bazel has a lot of dependencies and users don't want to install them just to build gvisor. These changes allows to run bazel in a docker container. A bazel cache is on the local file system (~/.cache/bazel), so incremental builds should be fast event after recreating a bazel container. Here is an example how to build runsc: make BAZEL_OPTIONS="build runsc:runsc" bazel Change-Id: I8c0a6d0c30e835892377fb6dd5f4af7a0052d12a PiperOrigin-RevId: 246570877

2019-04-03Fix index out of bounds in tty implementation.Kevin Krakauer
The previous implementation revolved around runes instead of bytes, which caused weird behavior when converting between the two. For example, peekRune would read the byte 0xff from a buffer, convert it to a rune, then return it. As rune is an alias of int32, 0xff was 0-padded to int32(255), which is the hex code point for ?. However, peekRune also returned the length of the byte (1). When calling utf8.EncodeRune, we only allocated 1 byte, but tried the write the 2-byte character ?. tl;dr: I apparently didn't understand runes when I wrote this.
