3d6049d0da Remove CAN_JOIN policy from Conpherence

ada9046e31 Fix a fulltext search issue where finding token length and stopwords could fail
Summary:
Ref T12137. If a database is missing the InnoDB or MyISAM table engines, the big combined query to get both will fail.

Instead, try InnoDB first and then MyISAM.

50e809e06f Fix an issue where recurring ghost events could go missing if queried with a limit
Summary:
Ref T11816. Depends on D17644. When you executed a query like "upcoming, limit 5 events" you might match some recurring events starting from, say, a year ago and repeating every month.

We'd then generate the first 5 ghosts for these events (say, last January, February, ... May) and later throw them out, so the correct events in the query window (say, this April) would never get generated.

Instead, generate ghosts beginning with the start of the window. The fix in D17644 to number results correctly allows us to do this.

Test Plan:
  - Made a query panel showing 5 events, scheduled an event long in the past, did not visit any of the instances of it so they didn't generate concrete objects.
  - Before the patch, near-future instances failed to show; after the patch, they show.

Summary:
Ref T11816. Two minor issues:

  - We used `$event`, not `$next_event`, as the event providing the PHID for "Busy at <event name>". This rendered "Busy at <most future event>" on the profile instead of "Busy at <next upcoming event".
  - The TTL computation used the event start, not the event end, so we could end up rebuilding the cache too often for users busy at an event.

Test Plan:
  - Attended an event in the near future and one later on.
  - Saw profile now say "busy at <near future event>" correctly.
  - In DarkConsole "Services" tab, no longer saw unnecessary cache refills while attending an event.

d450a08890 Support HMAC+SHA256 with automatic key generation and management
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.

08a4225437 Provide "bin/files integrity" for debugging, maintaining and backfilling integrity hashes
Summary:
Ref T12470. Provides an "integrity" utility which runs in these modes:

  - Verify: check that hashes match.
  - Compute: backfill missing hashes.
  - Strip: remove hashes. Useful for upgrading across a hash change.
  - Corrupt: intentionally corrupt hashes. Useful for debugging.
  - Overwrite: force hash recomputation.

Users normally shouldn't need to run any of this stuff, but this provides a reasonable toolkit for managing integrity hashes.

I'll recommend existing installs use `bin/files integrity --compute all` in the upgrade guidance to backfill hashes for existing files.

Test Plan:
  - Ran the script in many modes against various files, saw expected operation, including:
  - Verified a file, corrupted it, saw it fail.
  - Verified a file, stripped it, saw it have no hash.
  - Stripped a file, computed it, got a clean verify.
  - Stripped a file, overwrote it, got a clean verify.
  - Corrupted a file, overwrote it, got a clean verify.
  - Overwrote a file, overwrote again, got a no-op.

This simplification lets us render "epriestley accepted this revision." instead of "epriestley accepted this revision onbehalf of: long, list, of, every, default, reviewer, they, have, authority, over." so it's a good thing, but make it only affect the reviewers it's supposed to affect.

Test Plan:
  - Did an accept with a force-accept available but unchecked.
  - Before patch: incorrectly accepted all possible reviewers.
  - After patch: accepted only checked reviewers.
  - Also checked the force-accept box, accepted, got a proper force-accept.

2f4ff6a850 Fix bad "editPolicy" key in Paste
Summary: Fixes T12508. Files don't have an `editPolicy`, and we started actually checking that the keys are real things in D17616.

Test Plan:
  - Before patch: created a paste, got an "editPolicy" exception.
  - After patch: created a paste that worked properly.

d1a971e221 Support "Range: bytes=123-" requests
Summary:
Ref T12219. We currently only support Range requests like "bytes=123-456", but "bytes=123-", meaning "until end of file", is valid, and Chrome can send these requests.

I suspect this is the issue with T12219.

Test Plan: Used `nc local.phacility.com 80` to pipe raw requests, saw both "bytes=123-456" and "bytes=123-" requests satisfied correctly.

63828f5806 Store and verify content integrity checksums for files
Summary:
Ref T12470. This helps defuse attacks where an adversary can directly take control of whatever storage engine files are being stored in and change data there. These attacks would require a significant level of access.

Such attackers could potentially attack ranges of AES-256-CBC encrypted files by using Phabricator as a decryption oracle if they were also able to compromise a Phabricator account with read access to the files.

By storing a hash of the data (and, in the case of AES-256-CBC files, the IV) when we write files, and verifying it before we decrypt or read them, we can detect and prevent this kind of tampering.

This also helps detect mundane corruption and integrity issues.

Test Plan:
  - Added unit tests.
  - Uploaded new files, saw them get integrity hashes.
  - Manually corrupted file data, saw it fail. Used `bin/files cat --salvage` to read it anyway.
  - Tampered with IVs, saw integrity failures.

45fc4f6f64 Iterate over ranges correctly for encryped files
Summary:
Fixes T12079. Currently, when a file is encrypted and a request has "Content-Range", we apply the range first, //then// decrypt the result. This doesn't work since you can't start decrypting something from somewhere in the middle (at least, not with our cipher selection).

Instead: decrypt the result, //then// apply the range.

Test Plan: Added failing unit tests, made them pass

The root issue here is actually just that I cherry-picked stable locally
but did not push it. However, this is a minor issue I also caught while

58011a4e8e Upgrade File content hashing to SHA256
Summary:
Ref T12464. This defuses any possible SHA1-collision attacks by using SHA256, for which there is no known collision.

(SHA256 hashes are larger -- 256 bits -- so expand the storage column to 64 bytes to hold them.)

Test Plan:
  - Uploaded the same file twice, saw the two files generate the same SHA256 content hash and use the same underlying data.
  - Tried with a fake hash algorihtm ("quackxyz") to make sure the failure mode worked/degraded correctly if we don't have SHA256 for some reason. Got two valid files with two copies of the same data, as expected.

440ef5b7a7 Remove SHA1 file content hashing and make Files work without any hashing
Summary:
Ref T12464. We currently use SHA1 to detect when two files have the same content so we don't have to store two copies of the data.

Now that a SHA1 collision is known, this is theoretically dangerous. T12464 describes the shape of a possible attack.

Before replacing this with something more robust, shore things up so things work correctly if we don't hash at all. This mechanism is entirely optional; it only helps us store less data if some files are duplicates.

(This mechanism is also less important now than it once was, before we added temporary files.)

Test Plan: Uploaded multiple identical files, saw the uploads work and the files store separate copies of the same data.

1e181f0781 Deprecate "file.uploadhash"
Summary:
Ref T12464. This is a very old method which let you create a file on the server by referring to data which already existed in another file.

Basically, long ago, `arc` could say "Do you already have a file with hash X?" and just skip some work if the server did.

`arc` has not called this method since D13017, in May 2015.

Since it's easy to do so, just make this method pretend that it never has the file. Very old clients will continue to work, since they would expect this response in the common case and continue by uploading data.

Test Plan:
  - Grepped for `uploadhash` in Phabricator and Arcanist.
  - Called the method with the console, verified it returned `null`.
