2019-08-13Bump Bazel to v0.28.0Nicolas Lacasse
The new version has a change in behavior when using a custom platform: * Old behavior: rules that don't require a toolchain used host_platform, no matter what execution platforms are specified. * New behavior: rules that don't require a toolchain use standard platform resolution that starts with execution platforms. As part of this change, we cannot use the "extra_exectution_platforms" flag provided by the default bazelrc. I got rid of the default bazelrc file, and made our custom .bazelrc as minimal as possible. PiperOrigin-RevId: 263176802
2019-08-12Handle ENOSPC with a partial write.Nicolas Lacasse
Similar to the EPIPE case, we can return the number of bytes written before ENOSPC was encountered. If the app tries to write more, we can return ENOSPC on the next write. PiperOrigin-RevId: 263041648

2019-08-09netlink: return an error in nlmsgerrAndrei Vagin
Now if a process sends an unsupported netlink requests, an error is returned from the send system call. The linux kernel works differently in this case. It returns errors in the nlmsgerr netlink message. Reported-by: syzbot+571d99510c6f935202da@syzkaller.appspotmail.com PiperOrigin-RevId: 262690453
2019-08-09Create tests for common.Search().Brett Landau
Using the path_test.go file built by the Golang devs as a base, tests have been created to verify the functionality of common.Search(). A mock file system is created and fake test files are generated to see if they get picked up by common.Search(). Also included in this CL is a bug fix for proctor-nodejs that was discovered using this test. proctor-nodejs used to allow multiple "-" in its test name filter. The regex has been updated to prevent this. PiperOrigin-RevId: 262647263
2019-08-09Add congestion control states to sender.Bhasker Hariharan
This change just introduces different congestion control states and ensures the sender.state is updated to reflect the current state of the connection. It is not used for any decisions yet but this is required before algorithms like Eiffel/PRR can be implemented. Fixes #394 PiperOrigin-RevId: 262638292

2019-08-08Return a well-defined socket address type from socket funtions.Rahat Mahmood
Previously we were representing socket addresses as an interface{}, which allowed any type which could be binary.Marshal()ed to be used as a socket address. This is fine when the address is passed to userspace via the linux ABI, but is problematic when used from within the sentry such as by networking procfs files. PiperOrigin-RevId: 262460640
2019-08-08netstack: Don't start endpoint goroutines too soon on restore.Rahat Mahmood
Endpoint protocol goroutines were previously started as part of loading the endpoint. This is potentially too soon, as resources used by these goroutine may not have been loaded. Protocol goroutines may perform meaningful work as soon as they're started (ex: incoming connect) which can cause them to indirectly access resources that haven't been loaded yet. This CL defers resuming all protocol goroutines until the end of restore. PiperOrigin-RevId: 262409429

2019-08-06Fix for a panic due to writing to a closed accept channel.Bhasker Hariharan
This can happen because endpoint.Close() closes the accept channel first and then drains/resets any accepted but not delivered connections. But there can be connections that are connected but not delivered to the channel as the channel was full. But closing the channel can cause these writes to fail with a write to a closed channel. The correct solution is to abort any connections in SYN-RCVD state and drain/abort all completed connections before closing the accept channel. PiperOrigin-RevId: 261951132
2019-08-06Require pread/pwrite for splice file offsetsMichael Pratt

2019-08-05Alter Dockerfiles to include common.go and use a prebuilt JDK.Samantha Sample
After the refactoring of the proctor binaries, the Dockerfiles for each language must be altered to copy the common folder into their image. Additionally, Java has been changed to use the pre-built version of JDK-11 from Ubuntu, instead of building it from the source. This allows for a smaller image and faster test execution within the container. PiperOrigin-RevId: 261805158
2019-08-05Expand runtimes test suite to include Go, Java, PHP, and Python.Samantha Sample
This change adds functionality for running more languages using the runtimes test suite. It divides the languages into separate test functions, which each call the helper testLang function in the runtimes_test.go file. This allows them to be run individually or as a group. PiperOrigin-RevId: 261791935

syscall.EPOLLET has been defined with different values on amd64 and arm64(-0x80000000 on amd64, and 0x80000000 on arm64), while unix.EPOLLET has been unified this value to 0x80000000(golang/go#5328). ref #63 Signed-off-by: Haibo Xu <haibo.xu@arm.com> Change-Id: Id97d075c4e79d86a2ea3227ffbef02d8b00ffbb8

2019-08-02Job control: controlling TTYs and foreground process groups.Kevin Krakauer
(Don't worry, this is mostly tests.) 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.

2019-08-02Stops container if gofer is killedFabricio Voznika

2019-08-02Remove kernel.mounts.Nicolas Lacasse
We can get the mount namespace from the CreateProcessArgs in all cases where we need it. This also gets rid of kernel.Destroy method, since the only thing it was doing was DecRefing the mounts. Removing the need to call kernel.SetRootMountNamespace also allowed for some more simplifications in the container fs setup code. PiperOrigin-RevId: 261357060
2019-08-01Refactor ListTests() to common.Search().Brett Landau
This change removes the filepath.Walk() function from proctor- go, php, and nodejs. The filepath.Walk() is now defined in common.go in Search(). Each proctor binary passes root directory and testFilter arguments to Search(). proctor-python.go no longer uses filepath.Walk() to search for tests. There is a built-in list test function within python's language test suite so that is being used instead. PiperOrigin-RevId: 261242897
2019-08-01Set sandbox oom_score_adjIan Lewis
Set /proc/self/oom_score_adj based on oomScoreAdj specified in the OCI bundle. When new containers are added to the sandbox oom_score_adj for the sandbox and all other gofers are adjusted so that oom_score_adj is equal to the lowest oom_score_adj of all containers in the sandbox.

2019-07-31Fix test execution bugs in proctor-go and proctor-python.Brett Landau
proctor-go had a bug where it would incorrectly identify a tool test as a disk test. Instead of searching for the test on disk as the identification method, we now check if the test name ends in ".go". If the test ends in ".go" it is run as a disk test, otherwise the test is run as a tool test. Python tests need to be run from within the directory they exist. Functionality to split the test name from it's parent directory has been added and a cmd.Dir argument has been set. PiperOrigin-RevId: 261021693
2019-07-31Flipcall refinements.Jamie Liu
Note that some of these changes affect the protocol in backward-incompatible ways. - Replace use of "initially-active" and "initially-inactive" with "client" and "server" respectively for clarity. - Fix a race condition involving Endpoint.Shutdown() by repeatedly invoking FUTEX_WAKE until it is confirmed that no local thread is blocked in FUTEX_WAIT. - Drop flipcall.ControlMode.

2019-07-31Initialize kernel.unimplementedSyscallEmitter with a sync.Once.Nicolas Lacasse

2019-07-31Refactor proctor binaries to implement testRunner interface.Brett Landau
Shared code among proctor-*.go files has been refactored into common/common.go. The common package is imported in each proctor binary and a struct is created to implement the testRunner interface defined in common.go. This allows for the proctor binaries to be updated without having to copy/paste the same code across all files. There are no usage or functionality changes. PiperOrigin-RevId: 260967080
2019-07-31Fix ICMPv4 EchoReply packet checksumAustin Kiekintveld
The checksum was not being reset before being re-calculated and sent out. This caused the sent checksum to always be `0x0800`. Fixes #605. PiperOrigin-RevId: 260965059
