551b387164 CVE-2021-43791: Validate confirmation keys in /accounts/register/ codepath.
A confirmation link takes a user to the check_prereg_key_and_redirect
endpoint, before getting redirected to POST to /accounts/register/. The
problem was that validation was happening in the check_prereg_key_and_redirect
part and not in /accounts/register/ - meaning that one could submit an
expired confirmation key and be able to register.

We fix this by moving validation into /accouts/register/.

5b16ee0c08 auth: show _OR_ during login only when other methods are available.
There might be good reasons to have other external authentication
methods such as SAML configured, but none of them is available.

This happens, for example, when you have enabled SAML so that Zulip is
able to generate the metadata in XML format, but you haven't
configured an IdP yet. This commit makes sure that the phrase _OR_ is
only shown on the login/account page when there are actually other
authentication methods available. When they are just configured, but
not available yet, the page looks like as if no external
authentication methods are be configured.

We achieve this by deleting any_social_backend_enabled, which was very
similar to page_params.external_authentication_methods, which
correctly has one entry per configured SAML IdP.

e4ff372fc3 emails: Transform SMTPException into EmailNotDeliveredException.
Django's default SMTP implementation can raise various exceptions
when trying to send an email. In order to allow Zulip calling code
to catch fewer exceptions to handle any cause of "email not
sent", we translate most of them into EmailNotDeliveredException.
The non-translated exceptions concern the connection with the
SMTP server. They were not merged with the rest to keep some
details about the nature of these.

Tests are implemented in the test_send_email.py module.

55da3329ef registration: Rename source_realm field to source_realm_id.
Now that we are passing source realm's id instead of string_id in
source realm selector, it makes sense to rename the "source_realm" field
to "source_realm_id".

4262c04db1 registration: Encode source realm as an integer.
In the source realm selector, when we select a realm from which we want
to import the data, we pass the source realm's string_id. The problem
with this approach is that the string_id can be an empty string. This
commit makes the source_realm pass the realm's id instead of string_id.
Now, the source_realm's value will either be an integer or "" (empty
string) when we don't want to import settings from any realm.

a4c3224328 users: Remove redundant get_role_for_new_user in lib/create_user.py.
The function get_role_for_new_user was added to get role from the
invited_as value, as invited_as values were one of (1,2,3,4)
previously, but it was then changed to be the actual role value,
i.e. one of (100, 200, 400, 600), in 1f8f227444.

So, we can safely remove this function now and use invited_as value
directly and handle realm_creation case by using an if condition.

08d716c741 registration: Re-use the redirect_to_email_login_url helper.
In the case of reusing a registration link, reuse the

now showing a "you've already registered" note, which did not happen
previously, but that seems probably for the best, since the user did

c60f48c889 registration: Move "already in realm" check outside of validation.
Checking for `validate_email_not_already_in_realm` again (after the
form already did so), but only in the case that the form fails to
validate, means that we may be spending time pushing totally invalid
emails to the DB to check.  In the case of emails containing nulls,
this can even trigger a 500 error from PostgreSQL.

Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`.  The latter is
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.

Fixes #17015.

c44500175d database: Remove short_name from UserProfile.
A few major themes here:

    - We remove short_name from UserProfile
      and add the appropriate migration.

    - We remove short_name from various
      cache-related lists of fields.

    - We allow import tools to continue to
      write short_name to their export files,
      and then we simply ignore the field
      at import time.

    - We change functions like do_create_user,
      create_user_profile, etc.

    - We keep short_name in the /json/bots
      API.  (It actually gets turned into
      an email.)

    - We don't modify our LDAP code much
      here.

69c0959f34 python: Fix misuse of Optional types for optional parameters.
There seems to have been a confusion between two different uses of the
word “optional”:

• An optional parameter may be omitted and replaced with a default
  value.
• An Optional type has None as a possible value.

Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type.  But in
other cases, optional parameters should not have Optional type.  Fix
them.

365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

461d5b1a3e pysa: Introduce sanitizers, models, and inline marking safe.
This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.

If a user receives more than one invite to join a

f1ec02b40a auth: Add ExternalAuthResult to manage data in authentication flows.
This new type eliminates a bunch of messy code that previously
involved passing around long lists of mixed positional keyword and
arguments, instead using a consistent data object for communicating
about the state of an external authentication (constructed in
backends.py).

The result is a significantly more readable interface between
zproject/backends.py and zerver/views/auth.py, though likely more
could be done.

This has the side effect of renaming fields for internally passed
structures from name->full_name, next->redirect_to; this results in
most of the test codebase changes.

Modified by tabbott to add comments and collaboratively rewrite the
initialization logic.
