2021-04-02Implement cgroupfs.Rahat Mahmood
A skeleton implementation of cgroupfs. It supports trivial cpu and memory controllers with no support for hierarchies. PiperOrigin-RevId: 366561126
2021-01-22Detect failures in forked functionFabricio Voznika
EXPECT*/ASSERT* functions are not async-signal-safe and should not be called from the function passed to InForkedProcess. However, these happen accidentally sometimes but do no cause InForkedProcess to fail. Detect and notify in such cases. PiperOrigin-RevId: 353354540
2020-10-23Support VFS2 save/restore.Jamie Liu
Inode number consistency checks are now skipped in save/restore tests for reasons described in greatest detail in StatTest.StateDoesntChangeAfterRename. They pass in VFS1 due to the bug described in new test case SimpleStatTest.DifferentFilesHaveDifferentDeviceInodeNumberPairs. Fixes #1663 PiperOrigin-RevId: 338776148

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.

2019-09-16Migrate from gflags to absl flagsMichael 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
2019-09-06Load C++ rules from @rules_ccMichael Pratt
See https://github.com/bazelbuild/bazel/issues/8743. This will be required in Bazel 1.0. Protobuf was updated in https://github.com/protocolbuffers/protobuf/commit/bf0c69e1302fe9568fbe310cc54b37d20a9d16a3#diff-96239ee297e0a92ac6ff96a6bc434ef0. GoogleTest was updated in https://github.com/google/googletest/commit/6fd262ecf787d0dc2a91696fd4bf1d3ee1ebfa14. gflags has not yet been updated, so the repo still won't build with --incompatible_load_cc_rules_from_bzl.

Also enables tcgetpgrp(). - TIOCSPGRP - set foreground process group. Also enabled tcsetpgrp().

2019-01-10Fixing select call to not enforce RLIMIT_NOFILE.Zach Koopmans
Removing check to RLIMIT_NOFILE in select call. Adding unit test to select suite to document behavior. Moving setrlimit class from mlock to a util file for reuse. Fixing flaky test based on comments from Jamie. PiperOrigin-RevId: 228726131 Change-Id: Ie9dbe970bbf835ba2cca6e17eec7c2ee6fadf459
2018-12-27Fix deadlock between epoll_wait and getdentsFabricio Voznika
epoll_wait acquires EventPoll.listsMu (in EventPoll.ReadEvents) and then calls Inotify.Readiness which tries to acquire Inotify.evMu. getdents acquires Inotify.evMu (in Inotify.queueEvent) and then calls readyCallback.Callback which tries to acquire EventPoll.listsMu. The fix is to release Inotify.evMu before calling Queue.Notify. Queue is thread-safe and doesn't require Inotify.evMu to be held.
