7f11e8d740 Improve handling of email verification and "activated" accounts
Summary:
Small step forward which improves existing stuff or lays groudwork for future stuff:

  - Currently, to check for email verification, we have to single-query the email address on every page. Instead, denoramlize it into the user object.
    - Migrate all the existing users.
    - When the user verifies an email, mark them as `isEmailVerified` if the email is their primary email.
    - Just make the checks look at the `isEmailVerified` field.
  - Add a new check, `isUserActivated()`, to cover email-verified plus disabled. Currently, a non-verified-but-not-disabled user could theoretically use Conduit over SSH, if anyone deployed it. Tighten that up.
  - Add an `isApproved` flag, which is always true for now. In a future diff, I want to add a default-on admin approval queue for new accounts, to prevent configuration mistakes. The way it will work is:
    - When the queue is enabled, registering users are created with `isApproved = false`.
    - Admins are sent an email, "[Phabricator] New User Approval (alincoln)", telling them that a new user is waiting for approval.
    - They go to the web UI and approve the user.
    - Manually-created accounts are auto-approved.
    - The email will have instructions for disabling the queue.

I think this queue will be helpful for new installs and give them peace of mind, and when you go to disable it we have a better opportunity to warn you about exactly what that means.

Generally, I want to improve the default safety of registration, since if you just blindly coast through the path of least resistance right now your install ends up pretty open, and realistically few installs are on VPNs.

Test Plan:
  - Ran migration, verified `isEmailVerified` populated correctly.
  - Created a new user, checked DB for verified (not verified).
  - Verified, checked DB (now verified).
  - Used Conduit, People, Diffusion.

888b3839e7 Prepare to route VCS connections through SSH
Summary:
Fixes T2229. This sets the stage for a patch similar to D7417, but for SSH. In particular, SSH 6.2 introduced an `AuthorizedKeysCommand` directive, which lets us do this in a mostly-reasonable way without needing users to patch sshd (if they have a recent enough version, at least).

The way the `AuthorizedKeysCommand` works is that it gets run and produces an `authorized_keys`-style file fragment. This isn't ideal, because we have to dump every key into the result, but should be fine for most installs. The earlier patch against `sshd` passes the public key itself, which allows the script to just look up the key. We might use this eventually, since it can scale much better, so I haven't removed it.

Generally, auth is split into two scripts now which mostly do the same thing:

  - `ssh-auth` is the AuthorizedKeysCommand auth, which takes nothing and dumps the whole keyfile.
  - `ssh-auth-key` is the slightly cleaner and more scalable (but patch-dependent) version, which takes the public key and dumps only matching options.

I also reworked the argument parsing to be a bit more sane.

Test Plan:
This is somewhat-intentionally a bit obtuse since I don't really want anyone using it yet, but basically:

  - Copy `phabricator-ssh-hook.sh` to somewhere like `/usr/libexec/openssh/`, chown it `root` and chmod it `500`.
    - This script should probably also do a username check in the future.
  - Create a copy of `sshd_config` and fix the paths/etc. Point the KeyScript at your copy of the hook.
  - Start a copy of sshd (6.2 or newer) with `-f <your config file>` and maybe `-d -d -d` to foreground and debug.
  - Run `ssh -p 2222 localhost` or similar.

Specifically, I did this setup and then ran a bunch of commands like:

  - `ssh host` (denied, no command)
  - `ssh host ls` (denied, not supported)
  - `echo '{}' | ssh host conduit conduit.ping` (works)

90b83d7a92 Fix logged-out Diffusion calls to Conduit
Summary:
Conduit doesn't currently have an analog to "shouldAllowPublic", so the recent policy checks added here caught legitimate Conduit calls when viewing Diffusion as a logged-out user.

Add `shouldAllowPublic()` and set it for all the Diffusion queries.

(More calls probably need this, but we can add it when we hit them.)

2a5c987c71 Lock policy queries to their applications
Summary:
While we mostly have reasonable effective object accessibility when you lock a user out of an application, it's primarily enforced at the controller level. Users can still, e.g., load the handles of objects they can't actually see. Instead, lock the queries to the applications so that you can, e.g., never load a revision if you don't have access to Differential.

This has several parts:

  - For PolicyAware queries, provide an application class name method.
  - If the query specifies a class name and the user doesn't have permission to use it, fail the entire query unconditionally.
  - For handles, simplify query construction and count all the PHIDs as "restricted" so we get a UI full of "restricted" instead of "unknown" handles.

Test Plan:
  - Added a unit test to verify I got all the class names right.
  - Browsed around, logged in/out as a normal user with public policies on and off.
  - Browsed around, logged in/out as a restricted user with public policies on and off. With restrictions, saw all traces of restricted apps removed or restricted.

073cb0e78c Make PhabricatorPolicyInterface require a getPHID() method
Summary:
Ref T603. This cleans up an existing callsite in the policy filter, and opens up some stuff in the future.

Some policy objects don't have real PHIDs:

  PhabricatorTokenGiven
  PhabricatorSavedQuery
  PhabricatorNamedQuery
  PhrequentUserTime
  PhabricatorFlag
  PhabricatorDaemonLog
  PhabricatorConduitMethodCallLog
  ConduitAPIMethod
  PhabricatorChatLogEvent
  PhabricatorChatLogChannel

Although it would be reasonable to add real PHIDs to some of these (like `ChatLogChannel`), it probably doesn't make much sense for others (`DaemonLog`, `MethodCallLog`). Just let them return `null`.

Also remove some duplicate `$id` and `$phid` properties. These are declared on `PhabricatorLiskDAO` and do not need to be redeclared.

Test Plan: Ran the `testEverythingImplemented` unit test, which verifies that all classes conform to the interface.

c3b2184977 Mostly modernize Conduit logs

  - Add GC support to conduit logs.
  - Add Query support to conduit logs.
  - Record the actual user PHID.
  - Show client name.
  - Support querying by specific method, so I can link to this from a setup issue.

@wez, this migration may not be fast. It took about 8 seconds for me to migrate 800,000 rows in the `conduit_methodcalllog` table. This adds a GC which should keep the table at a more manageable size in the future.

You can safely delete all data older than 30 days from this table, although you should do it by `id` instead of `dateCreated` since there's no key on `dateCreated` until this patch.

Test Plan:
  - Ran GC.
  - Looked at log UI.
  - Ran Conduit methods.

e78898970a Implement SSHD glue and Conduit SSH endpoint
Summary:
  - Build "sshd-auth" (for authentication) and "sshd-exec" (for command execution) binaries. These are callable by "sshd-vcs", located [[https://github.com/epriestley/sshd-vcs | in my account on GitHub]]. They are based on precursors [[https://github.com/epriestley/sshd-vcs-glue | here on GitHub]] which I deployed for TenXer about a year ago, so I have some confidence they at least basically work.
    - The problem this solves is that normally every user would need an account on a machine to connect to it, and/or their public keys would all need to be listed in `~/.authorized_keys`. This is a big pain in most installs. Software like Gitosis/Gitolite solve this problem by giving you an easy way to add public keys to `~/.authorized_keys`, but this is pretty gross.
    - Roughly, instead of looking in `~/.authorized_keys` when a user connects, the patched sshd instead runs `echo <public key> | sshd-auth`. The `sshd-auth` script looks up the public key and authorizes the matching user, if they exist. It also forces sshd to run `sshd-exec` instead of a normal shell.
    - `sshd-exec` receives the authenticated user and any command which was passed to ssh (like `git receive-pack`) and can route them appropriately.
    - Overall, this permits a single account to be set up on a server which all Phabricator users can connect to without any extra work, and which can safely execute commands and apply appropriate permissions, and disable users when they are disabled in Phabricator and all that stuff.
  - Build out "sshd-exec" to do more thorough checks and setup, and delegate command execution to Workflows (they now exist, and did not when I originally built this stuff).
  - Convert @btrahan's conduit API script into a workflow and slightly simplify it (ConduitCall did not exist at the time it was written).

The next steps here on the Repository side are to implement Workflows for Git, SVN and HG wire protocols. These will mostly just proxy the protocols, but also need to enforce permissions. So the approach will basically be:

  - Implement workflows for stuff like `git receive-pack`.
  - These workflows will implement enough of the underlying protocol to determine what resource the user is trying to access, and whether they want to read or write it.
  - They'll then do a permissons check, and kick the user out if they don't have permission to do whatever they are trying to do.
  - If the user does have permission, we just proxy the rest of the transaction.

Next steps on the Conduit side are more simple:

  - Make ConduitClient understand "ssh://" URLs.

Test Plan: Ran `sshd-exec --phabricator-ssh-user epriestley conduit differential.query`, etc. This will get a more comprehensive test once I set up sshd-vcs.

ee392ada93 Add user parameter to differential.createrevision
Summary: arc incorrectly passes a "user" parameter to differential.createrevision (long ago, we respected it, I think). After D4191 this fatals. Provide a stub call until the next version bump.

0b9c54a6bb Detect missing 'params' in Conduit calls
Summary:
Suhosin has about 50 options for filtering input variables, doucmented here:

http://www.hardened-php.net/suhosin/configuration.html

The default behavior of Suhosin is to drop the variable entirely if it violates any of the rules, then continue with the request. It doesn't affect 'php://input' and doesn't drop other variables, so it evades existing detection, and we can't figure out that it's happened at runtime. We could add blanket checks (Suhosin enabled + suhosin.filter.action set to nothing means this may happen, and will be undetectable if it does happen) but can't tailor a check or recovery to this specific problem.

Instead, raise a better error in the specific case where we encounter this, which is Conduit calls of "arc diff" of files over 1MB (the default POST limit). In these cases, Suhosin drops the variable entirely. If there is no 'params', scream. We never encounter this case normall (`arc`, including `arc call-conduit`, always sends this parameter) although other clients might omit it. The only exception is the web console with `conduit.ping`, which submits nothing; make it submit something so it keeps working.

See also https://github.com/facebook/phabricator/issues/233#issuecomment-11186074

Test Plan: Brought up a Debian + Suhosin box, verified the behavior of Suhosin, made requests with and without 'params'.
