Summary:
@alok reported a vulnerability where Flash will run carefully-crafted plain text
files.
When the user requests a raw file, cache it into Files if it isn't already
there. Then redirect them to Files. This solves the problem by executing the
SWF/TXT with CDN-domain permissions, not content-domain permissions, provided
the install is correctly configured. (Followup diff coming to make this more
universally true.)
NOTE: We'll still show raw data in Diffusion. The barrier to XSS here is much
higher (you need commit access) but I'll do something similar there. We aren't
vulnerable in Paste, since we already use Files.
Test Plan: Clicked "View Old File", "View New File" in an alt-domain
configuration, got redirected to a cookie-free domain before being delivered the
response.

"Content-Disposition: attachment"
Summary:
We currently serve some files off the primary domain (with "Content-Disposition:
attachment" + a CSRF check) and some files off the alternate domain (without
either).
This is not sufficient, because some UAs (like the iPad) ignore
"Content-Disposition: attachment". So there's an attack that goes like this:
- Alice uploads xss.html
- Alice says to Bob "hey download this file on your iPad"
- Bob clicks "Download" on Phabricator on his iPad, gets XSS'd.
NOTE: This removes the CSRF check for downloading files. The check is nice to
have but only raises the barrier to entry slightly. Between iPad / sniffing /
flash bytecode attacks, single-domain installs are simply insecure. We could
restore the check at some point in conjunction with a derived authentication
cookie (i.e., a mini-session-token which is only useful for downloading files),
but that's a lot of complexity to drop all at once.
(Because files are now authenticated only by knowing the PHID and secret key,
this also fixes the "no profile pictures in public feed while logged out"
issue.)
Test Plan: Viewed, info'd, and downloaded files

@vrana patched an important external-CSRF-leaking hole recently (D1558), but
since we are sloppy in building this form it got caught in the crossfire.
We set action to something like "http://this.server.com/oauth/derp/", but that
triggers CSRF protection by removing CSRF tokens from the form. This makes OAuth

Summary:
We save search information and then redirect to a "/search/<query_id>/" URI in
order to make search URIs short and bookmarkable, and save query data for
analysis/improvement of search results.
Currently, there's a vague object enumeration security issue with using
sequential IDs to identify searches, where non-admins can see searches other
users have performed. This isn't really too concerning but we lose nothing by
using random keys from a large ID space instead.
- Drop 'authorPHID', which was unused anyway, so searches can not be
personally identified, even by admins.
- Identify searches by random hash keys, not sequential IDs.
- Map old queries' keys to their IDs so we don't break any existing bookmarked
URIs.
Test Plan: Ran several searches, got redirected to URIs with random hashes from
a large ID space rather than sequential integers.

Summary:
In D1515, I introduced some excessively-complicated semantics for detecting
connections that are lost while transactional. These semantics cause us to
reenter establishConnection() and establish twice as many connections as we need
in the common case.
We don't need a hook there at all -- it's sufficient to throw the exception
rather than retrying the query when we encounter it. This doesn't have
reentrancy problems.
Test Plan:
- Added some encapsulation-violating hooks and a unit test for them
- Verified we no longer double-connect.

- Disable fields by default, allow them to be enabled in config (these fields
were useful for me at Facebook when I had access to all the machines).
- Remove 'sourcePath' from Conduit methods other than differential.query.
- Condition 'sourcePath' field in Conduit on the caller being the revision
author. This is a bit hacky but not so awful.
Test Plan:
- Verified fields are gone by default and restored by configuration.
- Verified Conduit no longer returns these fields other than
differential.query.
- Verified field presence/absence according to authorship in
differential.query.
- Grepped around in arcanist to make sure we aren't relying on sourcePath.
There's a workflow in "arc merge" that technically might hit it, but I think
it's unreachable, definitely irrelvant (we never use source path as a
distinguisher under git/hg, and can't 'arc merge' in SVN) and it's going away
