2019-12-16Remove useless comments from p9/handlers.go.Nicolas Lacasse
These comments provided nothing, and have been copy-pasted into all implementations. The code is clear without them. I considered also removing the "handle implements handler.handle" comments, but will let those stay for now. PiperOrigin-RevId: 285876428

2019-12-16Implement checks for get/setxattr at the syscall layer.Dean Deng
Add checks for input arguments, file type, permissions, etc. that match the Linux implementation. A call to get/setxattr that passes all the checks will still currently return EOPNOTSUPP. Actual support will be added in following commits. Only allow user.* extended attributes for the time being. PiperOrigin-RevId: 285835159
2019-12-16Fix deadlock in overlay bindYong He
Copy up parent when binding UDS on overlayfs is supported in commit 02ab1f187cd24c67b754b004229421d189cee264. But the using of copyUp in overlayBind will cause sentry stuck, reason is dead lock in renameMu. 1 [Process A] Invoke a Unix socket bind operation renameMu is hold in fs.(*Dirent).genericCreate by process A 2 [Process B] Invoke a read syscall on /proc/task/mounts waitng on Lock of renameMu in fs.(*MountNamespace).FindMount 3 [Process A] Continue Unix socket bind operation wating on RLock of renameMu in fs.copyUp Root cause is recursive reading lock of reanmeMu in bind call trace, if there are writing lock between the two reading lock, then deadlock occured. Fixes #1397
2019-12-16Fix UDS bind cause fd leak in goferYong He
After the finalizer optimize in 76039f895995c3fe0deef5958f843868685ecc38 commit, clientFile needs to closed before finalizer release it. The clientFile is not closed if it is created via gofer.(*inodeOperations).Bind, this will cause fd leak which is hold by gofer process.

2019-12-15Set CPU number to CPU quotaAleksandr Razumov
When application is not cgroups-aware, it can spawn excessive threads which often defaults to CPU number. Introduce a opt-in flag that will set CPU number accordingly to CPU quota (if available). Fixes #1391

2019-12-12Add iptables testing framework.Kevin Krakauer
It would be preferrable to test iptables via syscall tests, but there are some problems with that approach: * We're limited to loopback-only, as syscall tests involve only a single container. Other link interfaces (e.g. fdbased) should be tested. * We'd have to shell out to call iptables anyways, as the iptables syscall interface itself is too large and complex to work with alone. * Running the Linux/native version of the syscall test will require root, which is a pain to configure, is inherently unsafe, and could leave host iptables misconfigured. Using the go_test target allows there to be no new test runner. PiperOrigin-RevId: 285274275

2019-12-11Add support for TCP_USER_TIMEOUT option.Bhasker Hariharan
The implementation follows the linux behavior where specifying a TCP_USER_TIMEOUT will cause the resend timer to honor the user specified timeout rather than the default rto based timeout. Further it alters when connections are timedout due to keepalive failures. It does not alter the behavior of when keepalives are sent. This is as per the linux behavior. PiperOrigin-RevId: 285099795

2019-12-11GCloudProducer: tunnel_dispatch, mock_recorder, and machine.Zach Koopmans
Work to import GCloudProducer, written in gerrit, which is too large to do in one CL. GCloudProducer sets up gcloud instances to run benchmark workloads. Included are: - gcloud_mock_recorder - used to Mock GCloudProducer - tunnel_dispatcher - updates to this module to bring it in line with the style guide - machine - updates to this module to bring it in line with the style guide All changes are independent of the rest of the changes, and should "just build".
