2021-07-23buildkite: deflake itimer testKevin Krakauer
The self-admittedly arbitrary threshold of 20% of alarms being sent to the main thread was being breached. I saw a run of of ~20-23% [1]. We should allow for a little more breathing room. 1 - https://buildkite.com/gvisor/pipeline/builds/7400 PiperOrigin-RevId: 386503482
2021-07-23Handle EINTR from socket syscalls in send/recv benchmark.Rahat Mahmood
The benchmark check fails if any of the socket syscalls fail with EINTR. We see this manifest in S/R lifecycles since S/R has a high probability of aborting these syscalls with EINTR. PiperOrigin-RevId: 386480365

2021-07-22kvm: set CR0.NE = 1Andrei Vagin
CR0.NE enables internal x87 floating point error reporting when set, else enables PC style x87 error detection. On AMD, the #MF exception isn't generated if CR0.NE isn't set. PiperOrigin-RevId: 386340269
2021-07-22runsc: Wait child processes without timeoutsAndrei Vagin
* First, we don't need to poll child processes. * Second, the 5 seconds timeout is too small if a host is overloaded. * Third, this can hide bugs in the code when we wait a process that isn't going to exit. PiperOrigin-RevId: 386337586

2021-07-22buildkite: move golang installation to VM bootKevin Krakauer
Rather than re-downloading and installing Go for each pipeline run, we should just do it at boot. PiperOrigin-RevId: 386320005

2021-07-21Add metric to count number of segments acknowledged by DSACK.Nayana Bidari
- Creates new metric "/tcp/segments_acked_with_dsack" to count the number of segments acked with DSACK. - Added check to verify the metric is getting incremented when a DSACK is sent in the unit tests. PiperOrigin-RevId: 386135949
2021-07-21buildkite: update GoKevin Krakauer
#6322 tried to update Go to 1.16, but existing nodes fail to upgrade due to the presence of old Go [1]. Specifically when trying to add Go to `/usr/bin`: ``` ln: failed to create symbolic link '/usr/bin/go': File exists ``` Also: - Removing `golang-go` also removes apt installs of `gcc` and `pkg-config`, so those are installed explicitly. - Add `-c` to wget, which will prevent re-downloading Go for each run. - Disable GO111MODULE when building cri-tools and containerd, since we're using pre-module versions of each. 1 - https://buildkite.com/gvisor/pipeline/builds/7285#3593244c-e411-472d-804a-9c7fbbd24762 PiperOrigin-RevId: 386106881

2021-07-20Don't kill container when volume is unmountedFabricio Voznika
The gofer session is killed when a gofer backed volume is unmounted. The gofer monitor catches the disconnect and kills the container. This changes the gofer monitor to only care about the rootfs connections, which cannot be unmounted. Fixes #6259 PiperOrigin-RevId: 385929039

2021-07-13Do not require O_PATH flag to enable verityChong Cai
Remove the hack in gVisor vfs that allows verity to bypass the O_PATH check, since ioctl is not allowed on fds opened with O_PATH in linux. Verity still opens the lowerFD with O_PATH to open it as a symlink, but the API no longer expects O_PATH to open a fd to be verity enabled. Now only O_FOLLOW should be specified when opening and enabling verity features. PiperOrigin-RevId: 384567833

2021-07-13netstack: atomically update buffer sizesKevin Krakauer

2021-07-13Deflake TestRouterSolicitationGhanan Gowripalan
Before this change, transmission of the first router solicitation races with the adding of an IPv6 link-local address. This change creates the NIC in the disabled state and is only enabled after the address is added (if required) to avoid this race. PiperOrigin-RevId: 384493553
2021-07-12netstack: move SO_SNDBUF/RCVBUF clamping logic out of //pkg/tcpipKevin Krakauer

2021-07-12Fix deadlock in procfsFabricio Voznika
Kernfs provides an internal mechanism to defer calls to `DecRef()` because on the last reference `Filesystem.mu` must be held and most places that need to call `DecRef()` are inside the lock. The same can be true for filesystems that extend kernfs. procfs needs to look up files and `DecRef()` them inside the `kernfs.Filesystem.mu`. If the files happen to be procfs files, it can deadlock trying to decrement if it's the last reference. This change extends the mechanism to external callers to defer DecRefs to `vfs.FileDescription` and `vfs.VirtualDentries`. PiperOrigin-RevId: 384361647
2021-07-12Drop dedicated benchmark lifecycle.Adin Scannell
Instead, roll the output scraping into the main runner. Pass a perf flag to the runner in order to control leak checking, apply tags via the macro and appropriately disable logging. This may be removed in the future. PiperOrigin-RevId: 384348035
2021-07-12Fix stdios ownershipFabricio Voznika
Set stdio ownership based on the container's user to ensure the user can open/read/write to/from stdios. 1. stdios in the host are changed to have the owner be the same uid/gid of the process running the sandbox. This ensures that the sandbox has full control over it. 2. stdios owner owner inside the sandbox is changed to match the container's user to give access inside the container and make it behave the same as runc.
