Increase ssh wait timeout according to the target slowdown.

The way to diagnose generally depends on the issue.
E.g. do we need register dump to debug this issue?
Do we need host dmesg dump? Some diagnosis may be
directly specific to a particular problem (e.g. dumping
a particular debugfs/procfs file).
Pass Report to Diagnose to make this possible.

Currently we squash VerboseError which leads to too lengthy build error titles.
Handle verbose error more carefully.
|
| |
|
|
|
|
| |
Rather than writing the diagnosis to the kernel console, Diagnose can
now directly return the extra debugging info, which will be appended ot
the kernel console log.

* build/openbsd: minor cleanup (use tuples instead of maps)
* Grammar nits in comments.
* Simplify openbsd.Create, will defer when there's more than one error exit.
* pkg/build: Support copying kernel into GCE image
* Simple test for openbsd image copy build.
* Cleanup in case something failed before.
* Support multi-processor VMs on GCE.
* More debug
* Reformat
* OpenBSD gce image needs to be raw.
* GC
* Force format to GNU directly on Go 1.10 or newer.
* Use vmType passed as a parameter inside openbsd.go
* gofmt
* more fmt
* Can't use GENERIC.mp just yet.
* capitalize
* Copyright

We currently have this list in multiple places (somewhat diverged).
Specify this "overcommit" property in VM implementations.
In particular, we also want to allow overcommit for "vmm" type.

Diagnose is called on machine hang to try to get
some additional diagnostic information from it.
For now it's all stubs.

Make it possible to monitor health and operation
of all managers from dashboard.
1. Notify dashboard about internal syz-ci errors
(currently we don't know when/if they happen).
2. Send statistics from managers to dashboard.
|
| |
|
|
|
|
|
| |
Boot and minimally test images before declaring them as good
and switching to using them.
If image build/boot/test fails, upload report about this to dashboard.
|
| |
|
|
|
|
|
| |
Support custom pre-created images.
Support non-root user.
Use dir instead of pwd on windows.
Don't use sudo on windows.
|

Allows future VM tuning based on target OS/arch.

Sshkey is a property of image, which is in manager config.
Move sshkey to the same location as image.
The motivation for the move is as follows.
Continuous build produces an image and the key,
both need to be passed manager instance.
Continuous build system should not distinguish
different VM types and mess with their configs.
NOTE FOR USERS: this breaks manager configs again.
Hopefully the last time for now. Docs are updated.

VM infrastructure currently has several problems:
- Config struct is complete mess with a superset of params for all VM types
- verification of Config is mess spread across several places
- there is no place where VM code could do global initialization
like creating GCE connection, uploading GCE image to GCS,
matching adb devices with consoles, etc
- it hard to add private VM implementations
such impl would need to add code to config package
which would lead to constant merge conflicts
- interface for VM implementation is mixed with interface for VM users
this does not allow to provide best interface for both of them
- there is no way to add common code for all VM implementations
This change solves these problems by:
- splitting VM interface for users (vm package) and VM interface
for VM implementations (vmimpl pacakge), this in turn allows
to add common code
- adding Pool concept that allows to do global initialization
and config checking at the right time
- decoupling manager config from VM-specific config
each VM type now defines own config
Note: manager configs need to be changed after this change:
VM-specific parts are moved to own "vm" subobject.
Note: this change also drops "local" VM type.
Its story was long unclear and there is now syz-stress which solves the same problem.
