Summary:
Ref T12509. This adds support for HMAC+SHA256 (instead of HMAC+SHA1). Although HMAC+SHA1 is not currently broken in any sense, SHA1 has a well-known collision and it's good to look at moving away from HMAC+SHA1.
The new mechanism also automatically generates and stores HMAC keys.
Currently, HMAC keys largely use a per-install constant defined in `security.hmac-key`. In theory this can be changed, but in practice essentially no install changes it.
We generally (in fact, always, I think?) don't use HMAC digests in a way where it matters that this key is well-known, but it's slightly better if this key is unique per class of use cases. Principally, if use cases have unique HMAC keys they are generally less vulnerable to precomputation attacks where an attacker might generate a large number of HMAC hashes of well-known values and use them in a nefarious way. The actual threat here is probably close to nonexistent, but we can harden against it without much extra effort.
Beyond that, this isn't something users should really have to think about or bother configuring.
Test Plan:
- Added unit tests.
- Used `bin/files integrity` to verify, strip, and recompute hashes.
- Tampered with a generated HMAC key, verified it invalidated hashes.

Summary:
The goal is to make fulltext search back-ends more extensible, configurable and robust.
When this is finished it will be possible to have multiple search storage back-ends and
potentially multiple instances of each.
Individual instances can be configured with roles such as 'read', 'write' which control
which hosts will receive writes to the index and which hosts will respond to queries.
These two roles make it possible to have any combination of:
* read-only
* write-only
* read-write
* disabled
This 'roles' mechanism is extensible to add new roles should that be needed in the future.
In addition to supporting multiple elasticsearch and mysql search instances, this refactors
the connection health monitoring infrastructure from PhabricatorDatabaseHealthRecord and
utilizes the same system for monitoring the health of elasticsearch nodes. This will
allow Wikimedia's phabricator to be redundant across data centers (mysql already is,
elasticsearch should be as well).
The real-world use-case I have in mind here is writing to two indexes (two elasticsearch clusters
in different data centers) but reading from only one. Then toggling the 'read' property when
we want to migrate to the other data center (and when we migrate from elasticsearch 2.x to 5.x)
Hopefully this is useful in the upstream as well.
Remaining TODO:
* test cases
* documentation
Test Plan:
(WARNING) This will most likely require the elasticsearch index to be deleted and re-created due to schema changes.
Tested with elasticsearch versions 2.4 and 5.2 using the following config:
```lang=json
"cluster.search": [
{
"type": "elasticsearch",
"hosts": [
{
"host": "localhost",
"roles": { "read": true, "write": true }
}
],
"port": 9200,
"protocol": "http",
"path": "/phabricator",
"version": 5
},
{
"type": "mysql",
"roles": { "write": true }
}
]
Also deployed the same changes to Wikimedia's production Phabricator instance without any issues whatsoever.

Summary:
Fixes T12400. Adds a "Has MFA" filter to People so you can figure out who you need to harass before turning on "require MFA".
When you run this as a non-admin, you don't currently actually hit the exception: the query just doesn't work. I think this is probably okay, but if we add more of these it might be better to make the "this didn't work" more explicit since it could be confusing in some weird edge cases (like, an administrator sending a non-administrator a link which they expect will show the non-administrator some interesting query results, but they actually just get no constraint). The exception is more of a fail-safe in case we make application changes in the future and don't remember this weird special case.
Test Plan:
- As an administrator and non-administrator, used People and Conduit to query MFA, no-MFA, and don't-care-about-MFA. These queries worked for an admin and didn't work for a non-admin.
- Viewed the list as an administrator, saw MFA users annotated.
- Viewed config help, clicked link as an admin, ended up in the right place.

Summary:
Fixes T12195. For the past few years, Recaptcha (now part of Google) has supported
a new, "no captcha" one-click user interface. This new UI is stable, doesn't
require any typing or reading words, and can even work without JavaScript (if
the administrator enables it on the Recaptcha side).
Furthermore, the new Recaptcha has a completely trivial API that can be dealt
with in a few lines of code. Thus, the external `recaptcha` php library is now
gone.
This API is a complete replacement for the old one, and does not require any
upgrade path for users or Phabricator administrators - public and secret keys
for the "new" Recaptcha UI are the exact same as the "classic" Recaptcha. Any
old Recaptcha keys for a domain will continue to work.
Note that Google is currently testing Yet Another new Captcha API, called
"Invisible reCAPTCHA", that will not require user interaction at all. In fact,
the user will not even be aware there //is even a captcha form//, as far as I
understand. However, this new API is 1) in beta, 2) requires new Recaptcha keys
(so it cannot be a drop-in replacement), and 3) requires more drastic API
changes, as form submission buttons must instead invoke JavaScript code, rather
than a token being passed along with the form submission. This would require far
more extensive changes to the controllers. Maybe when it's several years old, it
can be considered.
Signed-off-by: Austin Seipp <aseipp@pobox.com>
Test Plan:
Created a brand-new Phabricator installation, saw the new Captcha UI
on administrator sign up. Logged out, made 5 invalid login attempts, and saw the
new Captcha UI. Reworked the conditional to invert the condition, etc to test
and make sure the API responded properly.

In modern Phabricator, you can subclass `SiteConfig` to provide dynamic configuration, and we do so in the Phacility cluster. This lets you change any config, and change in response to requests (e.g., for instancing) and is generally more powerful than this mechanism was.
This configuration provider theoretically let you roll your own replication or partitioning, but in practice I believe no one ever did, and no one ever could have anyway without more support in the upstream (for migrations, read-after-write, etc).

- Provide a new configuation option, `keyring`, for specifying encryption keys.
- One key may be marked as `default`. This activates AES256 encryption for Files.
- Add `bin/files generate-key`. This is helps when generating valid encryption keys.
- Add `bin/files encode`. This changes the storage encoding of a file, and helps test encodings and migrate existing data.
- Add `bin/files cycle`. This re-encodes the block key with a new master key, if your master key leaks or you're just paraonid.
- Document all these options and behaviors.
Test Plan:
- Configured a bad `keyring`, hit a bunch of different errors.
- Used `bin/files generate-key` to try to generate bad keys, got appropriate errors ("raw doesn't support keys", etc).
- Used `bin/files generate-key` to generate an AES256 key.
- Put the new AES256 key into the `keyring`, without `default`.
- Uploaded a new file, verified it still uploaded as raw data (no `default` key yet).
- Used `bin/files encode` to change a file to ROT13 and back to raw. Verified old data got deleted and new data got stored properly.
- Used `bin/files encode --key ...` to explicitly convert a file to AES256 with my non-default key.
- Forced a re-encode of an AES256 file, verified the old data was deleted and a new key and IV were generated.
- Used `bin/files cycle` to try to cycle raw/rot13 files, got errors.
- Used `bin/files cycle` to cycle AES256 files. Verified metadata changed but file data did not. Verified file data was still decryptable with metadata.
- Ran `bin/files cycle --all`.
- Ran `encode` and `cycle` on chunked files, saw commands fail properly. These commands operate on the underlying data blocks, not the chunk metadata.
