The recently-upgraded gosec linter has a rule for archive extraction
code which may be vulnerable to directory traversal attacks, a.k.a. Zip
Slip. Gosec's detection is unfortunately prone to false positives,
however: it flags any filepath.Join call with an argument derived from a
tar.Header value, irrespective of whether the resultant path is used for
filesystem operations or if directory traversal attacks are guarded
against.
All of the lint errors reported by gosec appear to be false positives.

pkg/ is a collection of utility packages used by the Moby project without being specific to its internals.
Utility packages are kept separate from the moby core codebase to keep it as small and concise as possible.
If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the
Moby organization, to facilitate re-use by other projects. However that is not the priority.
The directory pkg is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good
place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
