Ramkumar Chinchani eadc9b65ed fix(security): limit API key creation body to 4 KiB (INPUT-2) (#3978)
Wrap req.Body with http.MaxBytesReader before io.ReadAll in
CreateAPIKey. Requests with bodies larger than MaxAPIKeyBodySize
(4 KiB) now return HTTP 413 instead of buffering arbitrary data.

Add the MaxAPIKeyBodySize constant, update the Swagger @Failure
annotation to document 413, and add a unit test.

Ramkumar Chinchani 35c29b95e4 fix(security): limit manifest PUT body to 4 MiB (INPUT-1) (#3977)
Wrap request.Body with http.MaxBytesReader before io.ReadAll in
UpdateManifest. Bodies exceeding MaxManifestBodySize (4 MiB) now
return HTTP 413 with a MANIFEST_INVALID error body instead of
buffering unlimited data into memory.

Add the MaxManifestBodySize constant and a unit test that sends an
oversized body and asserts the 413 status.

Vishwas R 5ae7a028d9 feat(cluster): Add support for request proxying for scale out (#2385)
* feat(cluster): initial commit for scale-out cluster

Signed-off-by: Ramkumar Chinchani <rchincha@cisco.com>

* feat(cluster): support shared storage scale out

This change introduces support for shared storage backed
zot cluster scale out.

New feature
Multiple stateless zot instances can run using the same shared
storage backend where each instance looks at a specific set
of repositories based on a siphash of the repository name to improve
scale as the load is distributed across multiple instances.
For a given config, there will only be one instance that can perform
dist-spec read/write on a given repository.

What's changed?
- introduced a transparent request proxy for dist-spec endpoints based on
siphash of repository name.
- new config for scale out cluster that specifies list of
cluster members.

peusebiu c6b822f3dd refactor(authz): use a struct for user access control info operations (#1682)
fix(authz): fix isAdmin not using groups to determine if a user is admin.
fix(authz): return 401 instead of 403

403 is correct as per HTTP spec
However authz is not part of dist-spec and clients know only about 401
So this is a compromise.

Andrei Aaron 77149aa85c refactor(extensions)!: refactor the extensions URLs and errors (#1636)
BREAKING CHANGE: The functionality provided by the mgmt endpoint has beed redesigned - see details below
BREAKING CHANGE: The API keys endpoint has been moved -  see details below
BREAKING CHANGE: The mgmt extension config has been removed - endpoint is now enabled by having both the search and the ui extensions enabled
BREAKING CHANGE: The API keys configuration has been moved from extensions to http>auth>apikey

mgmt and imagetrust extensions:
- separate the _zot/ext/mgmt into 3 separate endpoints: _zot/ext/auth, _zot/ext/notation, _zot/ext/cosign
- signature verification logic is in a separate `imagetrust` extension
- better hanling or errors in case of signature uploads: logging and error codes (more 400 and less 500 errors)
- add authz on signature uploads (and add a new middleware in common for this purpose)
- remove the mgmt extension configuration - it is now enabled if the UI and the search extensions are enabled

userprefs estension:
- userprefs are enabled if both search and ui extensions are enabled (as opposed to just search)

apikey extension is removed and logic moved into the api folder
- Move apikeys code out of pkg/extensions and into pkg/api
- Remove apikey configuration options from the extensions configuration and move it inside the http auth section
- remove the build label apikeys

other changes:
- move most of the logic adding handlers to the extensions endpoints out of routes.go and into the extensions files.
- add warnings in case the users are still using configurations with the obsolete settings for mgmt and api keys
- add a new function in the extension package which could be a single point of starting backgroud tasks for all extensions
- more clear methods for verifying specific extensions are enabled
- fix http methods paired with the UI handlers
- rebuild swagger docs

peusebiu 17d1338af1 feat: integrate openID auth logic and user profile management (#1381)
This change introduces OpenID authn by using providers such as Github,
Gitlab, Google and Dex.
User sessions are now used for web clients to identify
and persist an authenticated users session, thus not requiring every request to
use credentials.
Another change is apikey feature, users can create/revoke their api keys and use them
to authenticate when using cli clients such as skopeo.

eg:
login:
/auth/login?provider=github
/auth/login?provider=gitlab
and so on

logout:
/auth/logout

redirectURL:
/auth/callback/github
/auth/callback/gitlab
and so on

If network policy doesn't allow inbound connections, this callback wont work!
