2020-02-03Allow mlock in system call filtersMichael Pratt
Go 1.14 has a workaround for a Linux 5.2-5.4 bug which requires mlock'ing the g stack to prevent register corruption. We need to allow this syscall until it is removed from Go. PiperOrigin-RevId: 292967478

2020-01-28Add vfs.FileDescription to FD tableFabricio Voznika
FD table now holds both VFS1 and VFS2 types and uses the correct one based on what's set. Parts of this CL are just initial changes (e.g. sys_read.go, runsc/main.go) to serve as a template for the remaining changes. Updates #1487 Updates #1623 PiperOrigin-RevId: 292023223

2020-01-27Cleanup glog and add real caller information.Adin Scannell
In general, we've learned that logging must be avoided at all costs in the hot path. It's unlikely that the optimizations here were significant in any case, since buffer would certainly escape. This also adds a test to ensure that the caller identification works as expected, and so that logging can be benchmarked.

2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

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

2019-12-03Support IP_TOS and IPV6_TCLASS socket options for hostinet sockets.Dean Deng
There are two potential ways of sending a TOS byte with outgoing packets: including a control message in sendmsg, or setting the IP_TOS/IPV6_TCLASS socket options (for IPV4 and IPV6 respectively). This change lets hostinet support the latter. Fixes #1188 PiperOrigin-RevId: 283550925

2019-11-04Add NETLINK_KOBJECT_UEVENT socket supportMichael Pratt
NETLINK_KOBJECT_UEVENT sockets send udev-style messages for device events. gVisor doesn't have any device events, so our sockets don't need to do anything once created. systemd's device manager needs to be able to create one of these sockets. It also wants to install a BPF filter on the socket. Since we'll never send any messages, the filter would never be invoked, thus we just fake it out.

2019-11-01Allow the watchdog to detect when the sandbox is stuck during setup.Nicolas Lacasse
The watchdog currently can find stuck tasks, but has no way to tell if the sandbox is stuck before the application starts executing. This CL adds a startup timeout and action to the watchdog. If Start() is not called before the given timeout (if non-zero), then the watchdog will take the action. PiperOrigin-RevId: 277970577
