2019-05-30Add build guard to files using go:linknameFabricio Voznika
Funcion signatures are not validated during compilation. Since they are not exported, they can change at any time. The guard ensures that they are verified at least on every version upgrade. PiperOrigin-RevId: 250733742

2019-03-21Allow BP and OF can be called from user spaceYong He
Change the DPL from 0 to 3 for Breakpoint and Overflow, then user space could trigger Breakpoint and Overflow as excepected. Change-Id: Ibead65fb8c98b32b7737f316db93b3a8d9dcd648 PiperOrigin-RevId: 239736648
2019-03-14Decouple filemem from platform and move it to pgalloc.MemoryFile.Jamie Liu
This is in preparation for improved page cache reclaim, which requires greater integration between the page cache and page allocator. PiperOrigin-RevId: 238444706 Change-Id: Id24141b3678d96c7d7dc24baddd9be555bffafe4
2019-03-12Clarify the platform.File interface.Jamie Liu
- Redefine some memmap.Mappable, platform.File, and platform.Memory semantics in terms of File reference counts (no functional change). - Make AddressSpace.MapFile take a platform.File instead of a raw FD, and replace platform.File.MapInto with platform.File.FD. This allows kvm.AddressSpace.MapFile to always use platform.File.MapInternal instead of maintaining its own (redundant) cache of file mappings in the sentry address space.

2019-03-05Priority-inheritance futex implementationFabricio Voznika
It is Implemented without the priority inheritance part given that gVisor defers scheduling decisions to Go runtime and doesn't have control over it. PiperOrigin-RevId: 236989545 Change-Id: I714c8ca0798743ecf3167b14ffeb5cd834302560
2019-03-01ptrace: drop old FIXMEAdin Scannell
The globalPool uses a sync.Once mechanism for initialization, and no cleanup is strictly required. It's not really feasible to have the platform implement a full creation -> destruction cycle (due to the way filters are assumed to be installed), so drop the FIXME.

2018-12-10Validate FS_BASE in Task.CloneMichael Pratt
arch_prctl already verified that the new FS_BASE was canonical, but Task.Clone did not. Centralize these checks in the arch packages. Failure to validate could cause an error in PTRACE_SET_REGS when we try to switch to the app. PiperOrigin-RevId: 224862398 Change-Id: Iefe63b3f9aa6c4810326b8936e501be3ec407f14

2018-11-20Use RET_KILL_PROCESS if available in kernelFabricio Voznika
RET_KILL_THREAD doesn't work well for Go because it will kill only the offending thread and leave the process hanging. RET_TRAP can be masked out and it's not guaranteed to kill the process. RET_KILL_PROCESS is available since 4.14. For older kernel, continue to use RET_TRAP as this is the best option (likely to kill process, easy to debug).

2018-10-31kvm: simplify floating point logic.Adin Scannell
This reduces the number of floating point save/restore cycles required (since we don't need to restore immediately following the switch, this always happens in a known context) and allows the kernel hooks to capture state. This lets us remove calls like "Current()". PiperOrigin-RevId: 219552844 Change-Id: I7676fa2f6c18b9919718458aa888b832a7db8cab
