8e703c8c35 Provide a default "loadPage()" implementation on "CursorPagedPolicyAwareQuery"
Summary: Ref T13682. Many subclasses of "CursorPagedPolicyAwareQuery" have the same implementation of "loadPage()", and this is a sensible default behavior.

Test Plan: Examined changes to verify that all removed methods have the same behavior.

84b5ad09e6 Remove all readers and all nontrivial writers for "accountType" and "accountDomain" on "ExternalAccount"
Summary:
Depends on D21018. Ref T13493. Ref T6703. The "ExternalAccount" table has a unique key on `<accountType, accountDomain, accountID>` but this no longer matches our model of reality and changes in this sequence end writes to `accountID`.

Remove this key.

Then, remove all readers of `accountType` and `accountDomain` (and all nontrivial writers) because none of these callsites are well-aligned with plans in T6703.

This change has no user-facing impact today: all the rules about linking/unlinking/etc remain unchanged, because other rules currently prevent creation of more than one provider with a given "accountType".

Test Plan:
- Linked an OAuth1 account (JIRA).
- Linked an OAuth2 account (Asana).
- Used `bin/auth refresh` to cycle OAuth tokens.
- Grepped for affected symbols.
- Published an Asana update.
- Published a JIRA link.

bcaf60015a Write ExternalAccountIdentifiers when interacting with external authentication providers
Summary:
Depends on D21015. When we sync an external account and get a list of account identifiers, write them to the database.

Depends on D21010. Ref T13493. External accounts may have multiple different unique identifiers, most often when v1 of the API makes a questionable choice (and provies a mutable, non-unique, or PII identifier) and v2 of the API uses an immutable, unique, random identifier.

d22495a820 Make external link/refresh use provider IDs, switch external account MFA to one-shot
Summary:
Depends on D20113. Ref T6703. Continue moving toward a future where multiple copies of a given type of provider may exist.

Switch MFA from session-MFA at the start to one-shot MFA at the actual link action.

Add one-shot MFA to the unlink action. This theoretically prevents an attacker from unlinking an account while you're getting coffee, registering `alIce` which they control, adding a copy of your profile picture, and then trying to trick you into writing a private note with your personal secrets or something.

Test Plan: Linked and unlinked accounts. Refreshed account. Unlinked, then registered a new account. Unlinked, then relinked to my old account.

541d794c13 Give ExternalAccount a providerConfigPHID, tying it to a particular provider
Summary:
Depends on D20111. Ref T6703. Currently, each ExternalAccount row is tied to a provider by `providerType` + `providerDomain`. This effectively prevents multiple providers of the same type, since, e.g., two LDAP providers may be on different ports on the same domain. The `domain` also isn't really a useful idea anyway because you can move which hostname an LDAP server is on, and LDAP actually uses the value `self` in all cases. Yeah, yikes.

Instead, just bind each account to a particular provider. Then we can have an LDAP "alice" on seven different servers on different ports on the same machine and they can all move around and we'll still have a consistent, cohesive view of the world.

(On its own, this creates some issues with the link/unlink/refresh flows. Those will be updated in followups, and doing this change in a way with no intermediate breaks would require fixing them to use IDs to reference providerType/providerDomain, then fixing this, then undoing the first fix most of the way.)

Test Plan: Ran migrations, sanity-checked database. See followup changes for more comprehensive testing.

f0364eef8a Remove weird integration between Legalpad and the ExternalAccount table
Summary:
Depends on D20107. Ref T6703. Legalpad currently inserts "email" records into the external account table, but they're never used for anything and nothing else references them.

They also aren't necessary for anything important to work, and the only effect they have is making the UI say "External Account" instead of "None" under the "Account" column. In particular, the signatures still record the actual email address.

Stop doing this, remove all the references, and destroy all the rows.

(Long ago, Maniphest may also have done this, but no longer does. Nuance/Gatekeeper use a more modern and more suitable "ExternalObject" thing that I initially started adapting here before realizing that Legalpad doesn't actually care about this data.)

Test Plan: Signed documents with an email address, saw signature reflected properly in UI. Grepped for other callsites.

4fcb38a2a9 Move the Auth Provider edit flow toward a more modern layout
Summary:

As a step toward making this stuff easier to use and more modern, give them a separate view UI with normal actions, similar to basically every other type of object. Move the timeline and "Disable/Enable" to the view page (from the edit page and the list page, respectively).

6f3bd13cf5 Begin adding more guidance to the "One-Time Login" flow
Summary:
Ref T13244. See PHI774. If an install does not use password auth, the "one-time login" flow (via "Welcome" email or "bin/auth recover") is pretty rough. Current behavior:

  - If an install uses passwords, the user is prompted to set a password.
  - If an install does not use passwords, you're dumped to `/settings/external/` to link an external account. This is pretty sketchy and this UI does not make it clear what users are expected to do (link an account) or why (so they can log in).

Instead, improve this flow:

  - Password reset flow is fine.
  - (Future Change) If there are external linkable accounts (like Google) and the user doesn't have any linked, I want to give users a flow like a password reset flow that says "link to an external account".
  - (This Change) If you're an administrator and there are no providers at all, go to "/auth/" so you can set something up.
  - (This Change) If we don't hit on any other rules, just go home?

This may be tweaked a bit as we go, but basically I want to refine the "/settings/external/" case into a more useful flow which gives users more of a chance of surviving it.

Test Plan: Logged in with passwords enabled (got password reset), with nothing enabled as an admin (got sent to Auth), and with something other than passwords enabled (got sent home).

f0c6ee4823 Add "Contact Numbers" so we can send users SMS mesages
Summary:
Ref T920. To send you SMS messages, we need to know your phone number.

This adds bare-bone basics (transactions, storage, editor, etc).

From here:

**Disabling Numbers**: I'll let you disable numbers in an upcoming diff.

**Primary Number**: I think I'm just going to let you pick a number as "primary", similar to how email works. We could imagine a world where you have one "MFA" number and one "notifications" number, but this seems unlikely-ish?

**Publishing Numbers (Profile / API)**: At some point, we could let you say that a number is public / "show on my profile" and provide API access / directory features. Not planning to touch this for now.

**Non-Phone Numbers**: Eventually this could be a list of other similar contact mechanisms (APNS/GCM devices, Whatsapp numbers, ICQ number, twitter handle so MFA can slide into your DM's?). Not planning to touch this for now, but the path should be straightforward when we get there. This is why it's called "Contact Number", not "Phone Number".

**MFA-Required + SMS**: Right now, if the only MFA provider is SMS and MFA is required on the install, you can't actually get into Settings to add a contact number to configure SMS. I'll look at the best way to deal with this in an upcoming diff -- likely, giving you partial access to more of Setings before you get thorugh the MFA gate. Conceptually, it seems reasonable to let you adjust some other settings, like "Language" and "Accessibility", before you set up MFA, so if the "you need to add MFA" portal was more like a partial Settings screen, maybe that's pretty reasonable.

**Verifying Numbers**: We'll probably need to tackle this eventually, but I'm not planning to worry about it for now.

aa48373889 Update bin/auth MFA commands for the new "MFA Provider" indirection layer
Summary:
Ref T13222. This updates the CLI tools and documentation for the changes in D19975.

The flags `--type` and `--all-types` retain their current meaning. In most cases, `bin/auth strip --type totp` is sufficient and you don't need to bother looking up the relevant provider PHID. The existing `bin/auth list-factors` is also unchanged.

The new `--provider` flag allows you to select configs from a particular provider in a more granular way. The new `bin/auth list-mfa-providers` provides an easy way to get PHIDs.

(In the Phacility cluster, the "Strip MFA" action just reaches into the database and deletes rows manually, so this isn't terribly important. I verified that the code should still work properly.)

Test Plan:
  - Ran `bin/auth list-mfa-providers`.
  - Stripped by user / type / provider.
  - Grepped for `list-factors` and `auth strip`.
  - Hit all (?) of the various possible error cases.

0fcff78253 Convert user MFA factors to point at configurable "MFA Providers", not raw "MFA Factors"
Summary:
Ref T13222. Users configure "Factor Configs", which say "I have an entry on my phone for TOTP secret key XYZ".

Currently, these point at raw implementations -- always "TOTP" in practice.

To support configuring available MFA types (like "no MFA") and adding MFA types that need some options set (like "Duo", which needs API keys), bind "Factor Configs" to a "Factor Provider" instead.

In the future, several "Factors" will be available (TOTP, SMS, Duo, Postal Mail, ...). Administrators configure zero or more "MFA Providers" they want to use (e.g., "Duo" + here's my API key). Then users can add configs for these providers (e.g., "here's my Duo account").

Upshot:

  - Factor: a PHP subclass, implements the technical details of a type of MFA factor (TOTP, SMS, Duo, etc).
  - FactorProvider: a storage object, owned by administrators, configuration of a Factor that says "this should be available on this install", plus provides API keys, a human-readable name, etc.
  - FactorConfig: a storage object, owned by a user, says "I have a factor for provider X on my phone/whatever with secret key Q / my duo account is X / my address is Y".

Couple of things not covered here:

  - Statuses for providers ("Disabled", "Deprecated") don't do anything yet, but you can't edit them anyway.
  - Some `bin/auth` tools need to be updated.
  - When no providers are configured, the MFA panel should probably vanish.
  - Documentation.

Test Plan:
  - Ran migration with providers, saw configs point at the first provider.
  - Ran migration without providers, saw a provider created and configs pointed at it.
  - Added/removed factors and providers. Passed MFA gates. Spot-checked database for general sanity.

2c713b2d25 Add "Auth Messages" to support customizing onboarding/welcome flows
Summary:
Ref T13222. Long ago, we had a Config option (`welcome.html`) to let you dump HTML onto the login screen, but this was relatively hard to use and not good from a security perspective.

In some cases this was obsoleted by Dashboards, but there's at least some remaining set of use cases for actual login instructions on the login screen. For example, WMF has some guidance on //which// SSO mechanism to use based on what types of account you have. On `secure`, users assume they can register by clicking "Log In With GitHub" or whatever, and it might reduce frustration to tell them upfront that registration is closed.

Some other types of auth messaging could also either use customization or defaults (e.g., the invite/welcome/approve mail).

We could do this with a bunch of Config options, but I'd generally like to move to a world where there's less stuff in Config and more configuration is contextual. I think it tends to be easier to use, and we get a lot of fringe benefits (granular permissions, API, normal transaction logs, more abililty to customize workflows and provide contextual help/hints, etc). Here, for example, we can provide a remarkup preview, which would be trickier with Config.

This does not actually do anything yet.

TOTP //could// also have some configuration, like "bits of entropy" or "allowed window size" or whatever, if we want.

Add concrete objects for this and standard transaction / policy / query support. These objects don't do anything interesting yet and don't actually interact with MFA, this is just skeleton code for now.

b8cbfda07c Track MFA "challenges" so we can bind challenges to sessions and support SMS and other push MFA
Summary:
Ref T13222. See PHI873. Ref T9770.

Currently, we support only TOTP MFA. For some MFA (SMS and "push-to-app"-style MFA) we may need to keep track of MFA details (e.g., the code we SMS'd you). There isn't much support for that yet.

We also currently allow free reuse of TOTP responses across sessions and workflows. This hypothetically enables some "spyglass" attacks where you look at someone's phone and type the code in before they do. T9770 discusses this in more detail, but is focused on an attack window starting when the user submits the form. I claim the attack window opens when the TOTP code is shown on their phone, and the window between the code being shown and being submitted is //much// more interesting than the window after it is submitted.

To address both of these cases, start tracking MFA "Challenges". These are basically a record that we asked you to give us MFA credentials.

For TOTP, the challenge binds a particular timestep to a given session, so an attacker can't look at your phone and type the code into their browser before (or after) you do -- they have a different session. For now, this means that codes are reusable in the same session, but that will be refined in the future.

For SMS / push, the "Challenge" would store the code we sent you so we could validate it.

This is mostly a step on the way toward one-shot MFA, ad-hoc MFA in comment action stacks, and figuring out what's going on with Duo.

Test Plan:
  - Passed MFA normally.
  - Passed MFA normally, simultaneously, as two different users.
  - With two different sessions for the same user:
    - Opened MFA in A, opened MFA in B. B got a "wait".
    - Submitted MFA in A.
    - Clicked "Wait" a bunch in B.
    - Submitted MFA in B when prompted.
  - Passed MFA normally, then passed MFA normally again with the same code in the same session. (This change does not prevent code reuse.)

1d34238dc9 Upgrade sessions digests to HMAC256, retaining compatibility with old digests
Summary:
Ref T13222. Ref T13225. We store a digest of the session key in the session table (not the session key itself) so that users with access to this table can't easily steal sessions by just setting their cookies to values from the table.

Users with access to the database can //probably// do plenty of other bad stuff (e.g., T13134 mentions digesting Conduit tokens) but there's very little cost to storing digests instead of live tokens.

We currently digest session keys with HMAC-SHA1. This is fine, but HMAC-SHA256 is better. Upgrade:

  - Always write new digests.
  - We still match sessions with either digest.
  - When we read a session with an old digest, upgrade it to a new digest.

In a few months we can throw away the old code. When we do, installs that skip upgrades for a long time may suffer a one-time logout, but I'll note this in the changelog.

We could avoid this by storing `hmac256(hmac1(key))` instead and re-hashing in a migration, but I think the cost of a one-time logout for some tiny subset of users is very low, and worth keeping things simpler in the long run.

Test Plan:
  - Hit a page with an old session, got a session upgrade.
  - Reviewed sessions in Settings.
  - Reviewed user logs.
  - Logged out.
  - Logged in.
  - Terminated other sessions individually.
  - Terminated all other sessions.
  - Spot checked session table for general sanity.

6df278bea8 In "bin/ssh-auth", cache a structure instead of a flat file because paths may change at runtime
Summary:
Fixes T12397. Ref T13164. See PHI801.

Several installs have hit various use cases where the path on disk where Phabricator lives changes at runtime. Currently, `bin/ssh-auth` caches a flat file which includes the path to `bin/ssh-exec`, so this may fall out of date if `phabricator/` moves.

These use cases have varying strengths of legitimacy, but "we're migrating to a new set of hosts and the pool is half old machines and half new machines" seems reasonably compelling and not a problem entirely of one's own making.

Test Plan:
  - Compared output on `master` to output after change, found them byte-for-byte identical.
  - Moved `phabricator/` to `phabricator2/`, ran `bin/ssh-auth`, got updated output.
  - Added a new SSH key, saw it appear in the output.
  - Grepped for `AUTHFILE_CACHEKEY` (no hits).
  - Dropped the cache, verified that the file regenerates cleanly.

9c00a43784 Add a more modern object for storing password hashes
Summary:
Ref T13043. Currently:

  - Passwords are stored separately in the "VCS Passwords" and "User" tables and don't share as much code as they could.
  - Because User objects are all over the place in the code, password hashes are all over the place too (i.e., often somewhere in process memory). This is a very low-severity, theoretical sort of issue, but it could make leaving a stray `var_dump()` in the code somewhere a lot more dangerous than it otherwise is. Even if we never do this, third-party developers might. So it "feels nice" to imagine separating this data into a different table that we rarely load.
  - Passwords can not be //revoked//. They can be //deleted//, but users can set the same password again. If you believe or suspect that a password may have been compromised, you might reasonably prefer to revoke it and force the user to select a //different// password.

This change prepares to remedy these issues by adding a new, more modern dedicated password storage table which supports storing multiple password types (account vs VCS), gives passwords real PHIDs and transactions, supports DestructionEngine, supports revocation, and supports `bin/auth revoke`.

It doesn't actually make anything use this new table yet. Future changes will migrate VCS passwords and account passwords to this table.

(This also gives third party applications a reasonable place to store password hashes in a consistent way if they have some need for it.)

Test Plan: Added some basic unit tests to cover general behavior. This is just skeleton code for now and will get more thorough testing when applications move.

69053a40f9 Dirty the SSH key cache when usernames change
Summary:
Fixes T12554. The SSH key cache contains usernames, but is not currently dirtied on username changes.

An alternative solution would be to use user PHIDs instead of usernames in the file, which would make this unnecessary, but that would make debugging a bit harder. For now, I think this small added complexity is worth the easier debugging, but we could look at this again if cache management gets harder in the future.

Test Plan:
  - Added a key as `ducksey`, ran `bin/ssh-auth`, saw key immediately.
  - Renamed `ducksey` to `ducker`, ran `bin/ssh-auth`, saw username change immediately.
  - Added another key as `ducker`, ran `bin/ssh-auth`, saw key immediately.

c21a71f024 Cache generation of the SSH authentication keyfile for sshd
Summary:
Ref T11469. This isn't directly related, but has been on my radar for a while: building SSH keyfiles (particular for installs with a lot of keys, like ours) can be fairly slow.

At least one cluster instance is making multiple clone requests per second. While that should probably be rate limited separately, caching this should mitigate the impact of these requests.

This is pretty straightforward to cache since it's exactly the same every time, and only changes when users modify SSH keys (which is rare).

Test Plan:
  - Ran `bin/auth-ssh`, saw authfile generate.
  - Ran it again, saw it read from cache.
  - Changed an SSH key.
  - Ran it again, saw it regenerate.

0308d580d7 Deactivate SSH keys instead of destroying them completely
Summary:
Ref T10917. Currently, when you delete an SSH key, we really truly delete it forever.

This isn't very consistent with other applications, but we built this stuff a long time ago before we were as rigorous about retaining data and making it auditable.

In partiular, destroying data isn't good for auditing after security issues, since it means we can't show you logs of any changes an attacker might have made to your keys.

To prepare to improve this, stop destoying data. This will allow later changes to become transaction-oriented and show normal transaction logs.

The tricky part here is that we have a `UNIQUE KEY` on the public key part of the key.

Instead, I changed this to `UNIQUE (key, isActive)`, where `isActive` is a nullable boolean column. This works because MySQL does not enforce "unique" if part of the key is `NULL`.

So you can't have two rows with `("A", 1)`, but you can have as many rows as you want with `("A", null)`. This lets us keep the "each key may only be active for one user/object" rule without requiring us to delete any data.

Test Plan:
- Ran schema changes.
- Viewed public keys.
- Tried to add a duplicate key, got rejected (already associated with another object).
- Deleted SSH key.
- Verified that the key was no longer actually deleted from the database, just marked inactive (in future changes, I'll update the UI to be more clear about this).
- Uploaded a new copy of the same public key, worked fine (no duplicate key rejection).
- Tried to upload yet another copy, got rejected.
- Generated a new keypair.
- Tried to upload a duplicate to an Almanac device, got rejected.
- Generated a new pair for a device.
- Trusted a device key.
- Untrusted a device key.
- "Deleted" a device key.
- Tried to trust a deleted device key, got "inactive" message.
- Ran `bin/ssh-auth`, got good output with unique keys.
- Ran `cat ~/.ssh/id_rsa.pub | ./bin/ssh-auth-key`, got good output with one key.
- Used `auth.querypublickeys` Conduit method to query keys, got good active keys.

a837c3d73e Make temporary token storage/schema more flexible
Summary:
Ref T10603. This makes minor updates to temporary tokens:

  - Rename `objectPHID` (which is sometimes used to store some other kind of identifier instead of a PHID) to `tokenResource` (i.e., which resource does this token permit access to?).
  - Add a `userPHID` column. For LFS tokens and some other types of tokens, I want to bind the token to both a resource (like a repository) and a user.
  - Add a `properties` column. This makes tokens more flexible and supports custom behavior (like scoping LFS tokens even more tightly).

Test Plan:
- Ran `bin/storage upgrade -f`, got a clean upgrade.
- Viewed one-time tokens.
- Revoked one token.
- Revoked all tokens.
- Performed a one-time login.
- Performed a password reset.
- Added an MFA token.

In the AppSearch case, interfaces like Notifications, Calendar, Legalpad all need more custom layouts. I think this also leaves a resonable path forward for NUX as well. Also, not sure I implemented the class correctly, but assume thats easy to fix?

a4784e03ff [Redesign] Add Table, Collapse support to ObjectBox

Test Plan: I did a grep of `appendChild($table)` as well as searches for `PHUIObjectBoxView`, also with manual opening of hundreds of files. I'm sure I missed 5-8 places. If you just appendChild($table) nothing breaks, it just looks a little funny.

6f0d3b0796 Add a query/policy layer on top of SSH keys for Almanac
Summary:
Ref T5833. Currently, SSH keys are associated only with users, and are a bit un-modern. I want to let Almanac Devices have SSH keys so devices in a cluster can identify to one another.

For example, with hosted installs, initialization will go something like this:

  - A request comes in for `company.phacility.com`.
  - A SiteSource (from D10787) makes a Conduit call to Almanac on the master install to check if `company` is a valid install and pull config if it is.
  - This call can be signed with an SSH key which identifies a trusted Almanac Device.

In the cluster case, a web host can make an authenticated call to a repository host with similar key signing.

To move toward this, put a proper Query class on top of SSH key access (this diff). In following diffs, I'll:

  - Rename `userPHID` to `objectPHID`.
  - Move this to the `auth` database.
  - Provide UI for device/key association.

An alternative approach would be to build some kind of special token layer in Conduit, but I think that would be a lot harder to manage in the hosting case. This gives us a more direct attack on trusting requests from machines and recognizing machines as first (well, sort of second-class) actors without needing things like fake user accounts.

Test Plan:
  - Added and removed SSH keys.
  - Added and removed SSH keys from a bot account.
  - Tried to edit an unonwned SSH key (denied).
  - Ran `bin/ssh-auth`, got sensible output.
  - Ran `bin/ssh-auth-key`, got sensible output.

e46826ad36 Introduce CAN_EDIT for ExternalAccount, and make CAN_VIEW more liberal
Summary:
Fixes T3732. Ref T1205. Ref T3116.

External accounts (like emails used as identities, Facebook accounts, LDAP accounts, etc.) are stored in "ExternalAccount" objects.

Currently, we have a very restrictive `CAN_VIEW` policy for ExternalAccounts, to add an extra layer of protection to make sure users can't use them in unintended ways. For example, it would be bad if a user could link their Phabricator account to a Facebook account without proper authentication. All of the controllers which do sensitive things have checks anyway, but a restrictive CAN_VIEW provided an extra layer of protection. Se T3116 for some discussion.

However, this means that when grey/external users take actions (via email, or via applications like Legalpad) other users can't load the account handles and can't see anything about the actor (they just see "Restricted External Account" or similar).

Balancing these concerns is mostly about not making a huge mess while doing it. This seems like a reasonable approach:

  - Add `CAN_EDIT` on these objects.
  - Make that very restricted, but open up `CAN_VIEW`.
  - Require `CAN_EDIT` any time we're going to do something authentication/identity related.

This is slightly easier to get wrong (forget CAN_EDIT) than other approaches, but pretty simple, and we always have extra checks in place anyway -- this is just a safety net.

I'm not quite sure how we should identify external accounts, so for now we're just rendering "Email User" or similar -- clearly not a bug, but not identifying. We can figure out what to render in the long term elsewhere.

Test Plan:
  - Viewed external accounts.
  - Linked an external account.
  - Refreshed an external account.
  - Edited profile picture.
  - Viewed sessions panel.
  - Published a bunch of stuff to Asana/JIRA.
  - Legalpad signature page now shows external accounts.

cac61980f9 Add "temporary tokens" to auth, for SMS codes, TOTP codes, reset codes, etc
Summary:
Ref T4398. We have several auth-related systems which require (or are improved by) the ability to hand out one-time codes which expire after a short period of time.

In particular, these are:

  - SMS multi-factor: we need to be able to hand out one-time codes for this in order to prove the user has the phone.
  - Password reset emails: we use a time-based rotating token right now, but we could improve this with a one-time token, so once you reset your password the link is dead.
  - TOTP auth: we don't need to verify/invalidate keys, but can improve security by doing so.

This adds a generic one-time code storage table, and strengthens the TOTP enrollment process by using it. Specifically, you can no longer edit the enrollment form (the one with a QR code) to force your own key as the TOTP key: only keys Phabricator generated are accepted. This has no practical security impact, but generally helps raise the barrier potential attackers face.

Followup changes will use this for reset emails, then implement SMS multi-factor.

Test Plan:
  - Enrolled in TOTP multi-factor auth.
  - Submitted an error in the form, saw the same key presented.
  - Edited the form with web tools to provide a different key, saw it reject and the server generate an alternate.
  - Change the expiration to 5 seconds instead of 1 hour, submitted the form over and over again, saw it cycle the key after 5 seconds.
  - Looked at the database and saw the tokens I expected.
  - Ran the GC and saw all the 5-second expiry tokens get cleaned up.
