internal/derrors: add an internal errors package

An internal errors package is added that implements some simple common
error semantics.

derrors.Wrap allows errors to be annotated with a defer statement. It is
applied to the following packages / commands:

- cmd/cvetriage
- cmd/dbdiff
- cmd/report2cve
- internal

This pattern will be applied to other packages in later CLs.

The Go Vulnerability Database golang.org/x/vulndb

This repository is a prototype of the Go Vulnerability Database. Read the Draft Design.

Neither the code, nor the data, nor the existence of this repository is to be considered stable until an approved proposal.

Important: vulnerability entries in this repository are represented in an internal, unstable format that can and will change without notice.

Consuming database entries

Database clients must not rely on the contents of this repository. Instead, they can access the tree of JSON entries rooted at

https://storage.googleapis.com/go-vulndb/

An index.json file maps module paths to last modified timestamps (link).

For each module, a NAME.json file contains a list of vulnerability entries (example).

Note that this path and format are provisional and likely to change until an approved proposal.

Packages

Some of these packages can probably be coalesced, but for now are easier to work on in a more segmented fashion.

  • osv provides a package for generating OSV-style JSON vulnerability entries from a report.Report
  • client contains a client for accessing HTTP/fs based vulnerability databases, as well as a minimal caching implementation
  • cmd/dbdiff provides a tool for comparing two different versions of the vulnerability database
  • cmd/gendb provides a tool for converting YAML reports into JSON database
  • cmd/linter provides a tool for linting individual reports
  • cmd/report2cve provides a tool for converting YAML reports into JSON CVEs
