Mateusz Mandera 3f55c10685 saml: Rework SP-initiated logout config to support IdP-level config.
This gives more flexibility on a server with multiple organizations and
SAML IdPs. Such a server can have some organizations handled by IdPs
with SLO set up, and some without it set up. In such a scenario, having
a generic True/False server-wide setting is insufficient and instead
being able to specify the IdPs/orgs for SLO is needed.

Mateusz Mandera 0bb0220ebb saml: Implement SP-initiated Logout.
Closes #20084

This is the flow that this implements:
1. A logged-in user clicks "Logout".
2. If they didn't auth via SAML, just do normal logout. Otherwise:
3. Form a LogoutRequest and redirect the user to
https://idp.example.com/slo-endpoint?SAMLRequest=<LogoutRequest here>
4. The IdP validates the LogoutRequest, terminates its own user session
and redirects the user to
https://thezuliporg.example.com/complete/saml/?SAMLRequest=<LogoutResponse>
with the appropriate LogoutResponse. In case of failure, the
LogoutResponse is expected to express that.
5. Zulip validates the LogoutResponse and if the response is a success
response, it executes the regular Zulip logout and the full flow is
finished.

Alex Vandiver 8f8a9f6f04 sentry: Add frontend event monitoring.
Zulip already has integrations for server-side Sentry integration;
however, it has historically used the Zulip-specific `blueslip`
library for monitoring browser-side errors.  However, the latter sends
errors to email, as well optionally to an internal `#errors` stream.
While this is sufficient for low volumes of users, and useful in that
it does not rely on outside services, at higher volumes it is very
difficult to do any analysis or filtering of the errors.  Client-side
errors are exceptionally noisy, with many false positives due to
browser extensions or similar, so determining real real errors from a
stream of un-grouped emails or messages in a stream is quite
difficult.

Add a client-side Javascript sentry integration.  To provide useful
backtraces, this requires extending the pre-deploy hooks to upload the
source-maps to Sentry.  Additional keys are added to the non-public
API of `page_params` to control the DSN, realm identifier, and sample
rates.

Alex Vandiver 015a10637b docs: Document how to use SMTP without authentication.
This is the behaviour inherited from Django[^1].  While setting the
password to empty (`email_password = `) in
`/etc/zulip/zulip-secrets.conf` also would suffice, it's unclear what
the user would have been putting into `EMAIL_HOST_USER` in that
context.

Because we previously did not warn when `email_password` was not
present in `zulip-secrets.conf`, having the error message clarify the
correct configuration for disabling SMTP auth is important.

Fixes: #23938.

Alessandro Toppi ff89590558 auth: Add JWT-based user API key fetch.
This adds a new endpoint /jwt/fetch_api_key that accepts a JWT and can
be used to fetch API keys for a certain user. The target realm is
inferred from the request and the user email is part of the JWT.

A JSON containing an user API key, delivery email and (optionally)
raw user profile data is returned in response.
The profile data in the response is optional and can be retrieved by
setting the POST param "include_profile" to "true" (default=false).

Mateusz Mandera 16829bd84b auth: Fix up AzureAD Oauth2 docs and config.
This commit brings AzureAD config in line with other backends:
- SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET gets fetched in computed_settings.py
  instead of default_settings, consistent with github/gitlab/etc.
- SOCIAL_AUTH_AZUREAD_OAUTH2_KEY gets fetched in default_settings via
  get_secret(..., development_only=True) like other social backends, to
  allow easier set up in dev environment, in the dev-secrets.conf file.
- The secret gets renamed from azure_oauth2_secret to
  social_auth_azuread_oauth2_secret to have a consistent naming scheme with
  other social backends and with the SOCIAL_AUTH_AZUREAD_OAUTH2_KEY
  name. This is backwards-incompatible.

The instructions for setting it up are updated to fit how this is
currently done in AzureAD.

Alex Vandiver 4f93b4b6e4 uploads: Skip the outgoing proxy if S3_KEY is unset.
When the credentials are provided by dint of being run on an EC2
instance with an assigned Role, we must be able to fetch the instance
metadata from IMDS -- which is precisely the type of internal-IP
request that Smokescreen denies.

While botocore supports a `proxies` argument to the `Config` object,
this is not actually respected when making the IMDS queries; only the
environment variables are read from.  See
https://github.com/boto/botocore/issues/2644

As such, implement S3_SKIP_PROXY by monkey-patching the
`botocore.utils.should_bypass_proxies` function, to allow requests to
IMDS to be made without Smokescreen impeding them.

Fixes #20715.

Alex Vandiver 49ad188449 rate_limit: Add a flag to lump all TOR exit node IPs together.
TOR users are legitimate users of the system; however, that system can
also be used for abuse -- specifically, by evading IP-based
rate-limiting.

For the purposes of IP-based rate-limiting, add a
RATE_LIMIT_TOR_TOGETHER flag, defaulting to false, which lumps all
requests from TOR exit nodes into the same bucket.  This may allow a
TOR user to deny other TOR users access to the find-my-account and
new-realm endpoints, but this is a low cost for cutting off a
significant potential abuse vector.

If enabled, the list of TOR exit nodes is fetched from their public
endpoint once per hour, via a cron job, and cached on disk.  Django
processes load this data from disk, and cache it in memcached.
Requests are spared from the burden of checking disk on failure via a
circuitbreaker, which trips of there are two failures in a row, and
only begins trying again after 10 minutes.

YashRE42 778b7c0bdb links: Replace all references to Django docs to link to /3.2/ version.
Previously, our codebase contained links to various versions of the
Django docs, eg https://docs.djangoproject.com/en/1.8/ref/
request-response/#django.http.HttpRequest and https://
docs.djangoproject.com/en/2.2/ref/settings/#std:setting-SERVER_EMAIL
opening a link to a doc with an outdated Django version would show a
warning "This document is for an insecure version of Django that is no
longer supported. Please upgrade to a newer release!".

Most of these links are inside comments.

Following the replacement of these links in our docs, this commit uses
a search with the regex "docs.djangoproject.com/en/([0-9].[0-9]*)/"
and replaces all matches with "docs.djangoproject.com/en/3.2/".

All the new links in this commit have been generated by the above
replace and each link has then been manually checked to ensure that
(1) the page still exists and has not been moved to a new location
(and it has been found that no page has been moved like this), (2)
that the anchor that we're linking to has not been changed (and it has
been found that no anchor has been changed like this).

One comment where we mentioned a Django version in text before linking
to a page for that version has also been changed, the comment
mentioned the specific version when a change happened, and the history
is no longer relevant to us.

Mateusz Mandera 8ad7520180 ldap: Support alternative attrs to userAccountControl.
Fixes #17456.

The main tricky part has to do with what values the attribute should
have. LDAP defines a Boolean as
Boolean = "TRUE" / "FALSE"
so ideally we'd always see exactly those values. However,
although the issue is now marked as resolved, the discussion in
https://pagure.io/freeipa/issue/1259 shows how this may not always be
respected - meaning it makes sense for us to be more liberal in
interpreting these values.

Mateusz Mandera 4c9792b6a3 saml: Set requestedAuthnContext to False in prod_settings_template.
AuthnContextClassRef tells the IdP what forms of authentication the user
should use on the IdP's server for us to be okay with it. I don't think
there's a reason for us to enforce anything here and it should be up to
the IdP's configuration to handle authentication how it wants.

The default AuthnContextClassRef only allows PasswordProtectedTransport,
causing the IdP to e.g. reject authentication with Yubikey in AzureAD
SAML - which can be confusing for folks setting up SAML and is just not
necessary.

Mateusz Mandera fb3864ea3c auth: Change the look of SOCIAL_AUTH_SUBDOMAIN when directly opened.
SOCIAL_AUTH_SUBDOMAIN was potentially very confusing when opened by a
user, as it had various Login/Signup buttons as if there was a realm on
it. Instead, we want to display a more informative page to the user
telling them they shouldn't even be there. If possible, we just redirect
them to the realm they most likely came from.
To make this possible, we have to exclude the subdomain from
ROOT_SUBDOMAIN_ALIASES - so that we can give it special behavior.

Mateusz Mandera c54b48452d saml: Support syncing custom profile fields with SAML attributes.
Fixes #17277.

The main limitation of this implementation is that the sync happens if
the user authing already exists. This means that a new user going
through the sign up flow will not have their custom fields synced upon
finishing it. The fields will get synced on their consecutive log in via
SAML in the future. This can be addressed in the future by moving the
syncing code further down the codepaths to login_or_register_remote_user
and plumbing the data through to the user creation process.

We detail that limitation in the documentation.
