Summary: See T489. Provide slightly more detail so we can figure out if there's
a real issue here.
Test Plan:
Hit URIs like:
/differential/comment/preview/29/
/differential/comment/preview/29/?__ajax__=1
/differential/comment/preview/29/?__csrf__=1
..and got appropriate error messages.

Summary: HPHP has behaviorial differences from PHP which make this logic
problematic and we provide a good error message to users when there's a cookie
issue now, so unsplit the cookie logic and just clear the same cookie we'd
otherwise set, as per ssl / base domain.
Test Plan: Logged in and out of my local install.

Summary:
When an object is updated, record the content source for the update. This mostly
isn't terribly useful but one concrete thing I want to do with it is let admins
audit via-email replies more easily since there are a bunch of options which let
you do hyjinx if you intentionally configure them insecurely. I think having a
little more auditability around this feature is generally good. At some point
I'm going to turn this into a link admins can click to see details.
It also allows us to see how frequently different mechanisms are used, and lets
you see if someone is at their desk or on a mobile or whatever, at least
indirectly.
The "tablet" and "mobile" sources are currently unused but I figured I'd throw
them in anyway. SMS support should definitely happen at some point.
Not 100% sure about the design for this, I might change it to plain text at some
point.
Test Plan: Updated objects and saw update sources rendered.

purposes
Summary:
Browsers send port numbers (like ":443" or proxy ports) in the Host header and
we'll currently reject them with a message like:
> Blah is configured on "x.y.com" but you are accessing it on "x.y.com:443".
Instead, examine only the host part.
Test Plan: Had my local listen on port 81 and accessed Phabricator before/after
the change; it now works without throwing.

Summary:
In D758, I tightened the scope for which we issue cookies. Instead of setting
them on the whole domain we set them only on the subdomain, and we set them as
HTTPS only if the install is HTTPS.
However, this can leave the user with a stale HTTP cookie which the browser
sends and which never gets cleared. Handle this situation by:
- Clear all four <domain, https> pairs when clearing cookies ("nuke it from
orbit").
- Clear 'phsid' cookies when they're invalid.
Test Plan: Applied a hackier version of this patch to secure.phabricator.com and
was able to login with a stale HTTP cookie.

domain
Summary:
See D758, D759.
- Provide a strongly recommended setting which permits configuration of an
alternate domain.
- Lock cookies down better: set them on the exact domain, and use SSL-only if
the configuration is HTTPS.
- Prevent Phabriator from setting cookies on other domains.
This assumes D759 will land, it is not effective without that change.
Test Plan:
- Attempted to login from a different domain and was rejected.
- Logged out, logged back in normally.
- Put install in setup mode and verified it revealed a warning.
- Configured an alterate domain.
- Tried to view an image with an old URI, got a 400.
- Went to /files/ and verified links rendered to the alternate domain.
- Viewed an alternate domain file.
- Tried to view an alternate domain file without the secret key, got a 404.

Summary:
We don't currently validate CSRF tokens on this workflow. This allows an
attacker to upload arbitrary files on the user's behalf. Although I believe the
tight list of servable mime-types means that's more or less the end of the
attack, this is still a vulnerability.
In the long term, the right solution is probably to pass CSRF tokens on all Ajax
requests in an HTTP header (or just a GET param) or something like that.
However, this endpoint is unique and this is the quickest and most direct way to
close the hole.
Test Plan:
- Drop-uploaded files to Files, Maniphest, Phriction and Differential.
- Modified CSRF vaidator to use __csrf__.'x' and verified uploads and form
submissions don't work.

Summary:
We currently cycle CSRF tokens every hour and check for the last two valid ones.
This means that a form could go stale in as little as an hour, and is certainly
stale after two.
When a stale form is submitted, you basically get a terrible heisen-state where
some of your data might persist if you're lucky but more likely it all just
vanishes. The .js file below outlines some more details.
This is a pretty terrible UX and we don't need to be as conservative about CSRF
validation as we're being. Remedy this problem by:
- Accepting the last 6 CSRF tokens instead of the last 1 (i.e., pages are
valid for at least 6 hours, and for as long as 7).
- Using JS to refresh the CSRF token every 55 minutes (i.e., pages connected
to the internet are valid indefinitely).
- Showing the user an explicit message about what went wrong when CSRF
validation fails so the experience is less bewildering.
They should now only be able to submit with a bad CSRF token if:
- They load a page, disconnect from the internet for 7 hours, reconnect, and
submit the form within 55 minutes; or
- They are actually the victim of a CSRF attack.
We could eventually fix the first one by tracking reconnects, which might be
"free" once the notification server gets built. It will probably never be an
issue in practice.
Test Plan:
- Reduced CSRF cycle frequency to 2 seconds, submitted a form after 15
seconds, got the CSRF exception.
- Reduced csrf-refresh cycle frequency to 3 seconds, submitted a form after 15
seconds, got a clean form post.
- Added debugging code the the csrf refresh to make sure it was doing sensible
things (pulling different tokens, finding all the inputs).

Summary:
Fixes the issue caused by rPa0af5b66437719dba6136579c051982ab275e6a0. Prior to
that patch, isCommentInNewFile() returned $comment->getIsNewFile(). While this
was often the wrong value, it came from the database and was the integer 1 if
true.
After the patch, the function returns 'true' as a boolean, which is passed to JS
and then back to PHP, interpreted as an integer, and evaluates to 0.
To avoid this issue in general, provide an isBool() method on AphrontRequest
which interprets this correctly.
I will also revert the revert of rPa0af5b66437719dba6136579c051982ab275e6a0 when
I land this.
Test Plan:
Clicked "reply" on the right hand side of a diff, got a right-hand-side inline
comment.
