Summary:
Ref T4593. There are a variety of clever attacks against OAuth which involve changing the redirect URI to some other URI on the same domain which exhibits unexpected behavior in response to an OAuth request. The best approach to dealing with this is for providers to lock to a specific path and refuse to redirect elsewhere, but not all providers do this.
We haven't had any specific issues related to this, but the anchor issue in T4593 was only a step away.
To mitigate this in general, we can reject the OAuth2 `'code'` parameter on //every// page by default, and then whitelist it on the tiny number of controllers which should be able to receive it.
This is very coarse, kind of overkill, and has some fallout (we can't use `'code'` as a normal parameter in the application), but I think it's relatively well-contained and seems reasonable. A better approach might be to whitelist parameters on every controller (i.e., have each controller specify the parameters it can receive), but that would be a ton of work and probably cause a lot of false positives for a long time.
Since we don't use `'code'` normally anywhere (as far as I can tell), the coarseness of this approach seems reasonable.
Test Plan:
- Logged in with OAuth.
- Hit any other page with `?code=...` in the URL, got an exception.
- Grepped for `'code'` and `"code"`, and examined each use to see if it was impacted.

Summary:
We've been building a Jenkins plugin that allows you to use your Phabricator login details in Jenkins using the inbuilt OAuthServer. I noticed that when making a request to /oauthserver/auth/?client_id=&response_type=code I get an error back from the server.
I've traced this down to two bugs in PhabricatorOAuthServerAuthController, the first causes a null value error on $access_token_uri, and the second fails on userHasAuthorizedClient without a $scope array.
Test Plan: Go to /oauthserver/auth/?client_id=<client_id>&response_type=code and get a valid authorization code back

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

Summary:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.
Test Plan: Browsed around various affected tools; any issues here should throw/fail in a loud/obvious way.

Summary:
This diff makes the OAuthServer more compliant with the spec by
- making it return well-formatted error codes with error types from the spec.
- making it respect the "state" variable, which is a transparent variable the
client passes and the server passes back
- making it be super, duper compliant with respect to redirect uris
-- if specified in authorization step, check if its valid relative to the client
registered URI and if so save it
-- if specified in authorization step, check if its been specified in the access
step and error if it doesn't match or doesn't exist
-- note we don't make any use of it in the access step which seems strange but
hey, that's what the spec says!
This diff makes the OAuthServer suck less by
- making the "cancel" button do something in the user authorization flow
- making the client list view and client edit view be a bit more usable around
client secrets
- fixing a few bugs I managed to introduce along the way
Test Plan:
- create a test phabricator client, updated my conf, and then linked and
unlinked phabricator to itself
- wrote some tests for PhabricatorOAuthServer -- they pass!
-- these validate the various validate URI checks
- tried a few important authorization calls
--
http://phabricator.dev/oauthserver/auth/?client_id=X&state=test&redirect_uri=http://www.evil.com
--- verified error'd from mismatching redirect uri's
--- verified state parameter in response
--- verified did not redirect to client redirect uri
-- http://phabricator.dev/oauthserver/auth/?client_id=X w/ existing
authorization
--- got redirected to proper client url with error that response_type not
specified
-- http://phabricator.dev/oauthserver/auth/?client_id=X&response_type=code w/
existing authorization
--- got redirected to proper client url with pertinent code!
- tried a few important access calls
-- verified appropriate errors if missing any required parameters
-- verified good access code with appropriate other variables resulted in an
access token
- verified that if redirect_uri set correctly in authorization required for
access and errors if differs at all / only succeeds if exactly the same

for scope
Summary:
this patch makes the access token response "complete" relative to spec by
returning when it expires AND that the token_type is in fact 'Bearer'.
This patch also lays the groundwork for scope by fixing the underlying data
model and adding the first scope checks for "offline_access" relative to expires
and the "whoami" method. Further, conduit is augmented to open up individual
methods for access via OAuth generally to enable "whoami" access. There's also
a tidy little scope class to keep track of all the various scopes we plan to
have as well as strings for display (T849 - work undone)
Somewhat of a hack but Conduit methods by default have SCOPE_NOT_ACCESSIBLE. We
then don't even bother with the OAuth stuff within conduit if we're not supposed
to be accessing the method via Conduit. Felt relatively clean to me in terms
of additional code complexity, etc.
Next up ends up being T848 (scope in OAuth) and T849 (let user's authorize
clients for specific scopes which kinds of needs T850). There's also a bunch of
work that needs to be done to return the appropriate, well-formatted error
codes. All in due time...!
Test Plan:
verified that an access_token with no scope doesn't let me see
anything anymore. :( verified that access_tokens made awhile ago expire. :(

Summary:
adds a Phabricator OAuth server, which has three big commands:
- auth - allows $user to authorize a given client or application. if $user has already authorized, it hands an authoization code back to $redirect_uri
- token - given a valid authorization code, this command returns an authorization token
- whoami - Conduit.whoami, all nice and purdy relative to the oauth server.
Also has a "test" handler, which I used to create some test data. T850 will
delete this as it adds the ability to create this data in the Phabricator
product.
This diff also adds the corresponding client in Phabricator for the Phabricator
OAuth Server. (Note that clients are known as "providers" in the Phabricator
codebase but client makes more sense relative to the server nomenclature)
Also, related to make this work well
- clean up the diagnostics page by variabilizing the provider-specific
information and extending the provider classes as appropriate.
- augment Conduit.whoami for more full-featured OAuth support, at least where
the Phabricator client is concerned
What's missing here... See T844, T848, T849, T850, and T852.
Test Plan:
- created a dummy client via the test handler. setup development.conf to have
have proper variables for this dummy client. went through authorization and
de-authorization flows
- viewed the diagnostics page for all known oauth providers and saw
provider-specific debugging information
