2021-02-04Move getcpu() to core filter listMichael Pratt
Some versions of the Go runtime call getcpu(), so add it for compatibility. The hostcpu package already uses getcpu() on arm64. PiperOrigin-RevId: 355717757

2021-02-03[vfs] Make sticky bit check consistent with Linux.Ayush Ranjan
Our implementation of vfs.CheckDeleteSticky was not consistent with Linux, specifically not consistent with fs/linux.h:check_sticky(). One of the biggest differences was that the vfs implementation did not allow the owner of the sticky directory to delete files inside it that belonged to other users. This change makes our implementation consistent with Linux. Also adds an integration test to check for this. This bug is also present in VFS1. Updates #3027 PiperOrigin-RevId: 355557425

2021-02-02Stub out basic `runsc events --stat` CPU functionalityKevin Krakauer
Because we lack gVisor-internal cgroups, we take the CPU usage of the entire pod and divide it proportionally according to sentry-internal usage stats. This fixes `kubectl top pods`, which gets a pod's CPU usage by summing the usage of its containers. Addresses #172. PiperOrigin-RevId: 355229833

2021-02-02Add support for rate limiting out of window ACKs.Bhasker Hariharan
Netstack today will send dupACK's with no rate limit for incoming out of window segments. This can result in ACK loops for example if a TCP socket connects to itself (actually permitted by TCP). Where the ACK sent in response to packets being out of order itself gets considered as an out of window segment resulting in another ACK being generated. PiperOrigin-RevId: 355206877

2021-02-02Remove go_tool_library references.Adin Scannell
This is required only for the built-in bazel nogo functionality. Since we roll these targets manually via the wrappers, we don't need to use go_tool_library. The inconsistent use of these targets leads to conflicting instantiations of go_default_library and go_tool_library, which both contain the same output files. PiperOrigin-RevId: 355184975

2021-02-02Minor page tables improvements.Adin Scannell
* Make split safe. * Enable looking up next valid address. * Support mappings with !accessType.Any(), distinct from unmap. These changes allow for the use of pagetables in low-level OS packages, such as ring0, and allow for the use of pagetables for more generic address space reservation (by writing entries with no access specified).
