sayyedarib 5c993f0479 direct_message: Allow DMs to bots and self regardless of policy.
Previously, in DM disabled org messaging to bot was not working when
starting new conversation and adding bot as recipient because of not
updating on recipient change. And secondly, self messaging was not
allowed.
This commit ensures that the DM to bot and self are allowed irrespective
of dm restrictions.

tests: Verify DMs adhere to DM restriction policy.

Fixes #28412

Alex Vandiver 22837fc1b4 message_edit: Carry the QuerySet through as much as possible.
Rather than pass around a list of message objects in-memory, we
instead keep the same constructed QuerySet which includes the later
propagated messages (if any), and use that same query to pick out
affected Attachment objects, rather than limiting to the set of ids.
This is not necessarily a win -- the list of message-ids *may* be very
long, and thus the query may be more concise, easier to send to
PostgreSQL, and faster for PostgreSQL to parse.  However, the list of
ids is almost certainly better-indexed.

After processing the move, the QuerySet must be re-defined as a search
of ids (and possibly a very long list of such), since there is no
other way which is guaranteed to correctly single out the moved
messages.  At this point, it is mostly equivalent to the list of
Message objects, and certainly takes no less memory.

Alex Vandiver 822131fef4 message: Add a bulk_access_stream_messages_query method.
This applies access restrictions in SQL, so that individual messages
do not need to be walked one-by-one.  It only functions for stream
messages.

Use of this method significantly speeds up checks if we moved "all
visible messages" in a topic, since we no longer need to walk every
remaining message in the old topic to determine that at least one was
visible to the user.  Similarly, it significantly speeds up merging
into existing topics, since it no longer must walk every message in
the new topic to determine if the user could see at least one.

Finally, it unlocks the ability to bulk-update only messages the user
has access to, in a single query (see subsequent commit).

Tim Abbott 9efce0b16c create_user: Fix initial unreads ignoring private streams.
This logic was apparently missed when we implemented private streams
with shared history; the correct check is to look at whether the user
can access message history in the stream, which used to be equivalent
to whether it's a private stream.

Mateusz Mandera 6dd6fc045f realm_settings: Improve authentication_methods param validation.
The endpoint was lacking validation that the authentication_methods dict
submitted by the user made sense. So e.g. it allowed submitting a
nonsense key like NoSuchBackend or modifying the realm's configured
authentication methods for a backend that's not enabled on the server,
which should not be allowed.

Both were ultimately harmless, because:
1. Submitting NoSuchBackend would luckily just trigger a KeyError inside
   the transaction.atomic() block in do_set_realm_authentication_methods
   so it would actually roll back the database changes it was trying to
   make. So this couldn't actually create some weird
   RealmAuthenticationMethod entries.
2. Silently enabling or disabling e.g. GitHub for a realm when GitHub
   isn't enabled on the server doesn't really change anything. And this
   action is only available to the realm's admins to begin with, so
   there's no attack vector here.

test_supported_backends_only_updated wasn't actually testing anything,
because the state it was asserting:
```
        self.assertFalse(github_auth_enabled(realm))
        self.assertTrue(dev_auth_enabled(realm))
        self.assertFalse(password_auth_enabled(realm))
```

matched the desired state submitted to the API...
```
        result = self.client_patch(
            "/json/realm",
            {
                "authentication_methods": orjson.dumps(
                    {"Email": False, "Dev": True, "GitHub": False}
                ).decode()
            },
        )
```

so we just replace it with a new test that tests the param validation.

Prakhar Pratyush 1eef052bd1 actions: Rename *topic local variables to *topic_name.
This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.

Currently, we use *topic as the local variable name for
topic names.

We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.

Sahil Batra 92c1dfc248 message_send: Optimize checking access to DM recipients.
We previously used get_accessible_user_ids to check whether the
sender can access all DM recipients, which was not efficient as
it queries the Message table. This commit updates the code to
make sure we use get_inaccessible_user_ids which is much more
efficient as it limits the queries to only DM recipients and
also queries the Message table only if needed.

This can still be optimized further as mentioned in #27835 but
this commit is a nice first step.

result, users who had been removed from a stream, but still had an
account in the organization, could still view metadata for that
stream (including the stream name, description, settings, and an email
address used to send emails into the stream via the incoming email
integration). This potentially allowed users to see changes to a
stream’s metadata after they had lost access to the stream.

This bug was present in all Zulip releases prior to today's Zulip
Server 7.5.

Sahil Batra 432001656e streams: Remove "email_address" field from Subscription objects.
This commit removes "email_address" field from Subscription objects
and we would instead a new endpoint in next commit to get email
address for stream with proper access check.

This change also fixes the bug where we would include email address
for the unsubscribed private stream as well when user did not have
permission to send message to the stream, and having email allowed
the unsubscribed user to send message to the stream.

Note that the unsubscribed user can still send message to the stream
if the user had noted down the email before being unsubscribed
and the stream token is not changed after unsubscribing the user.

Prakhar Pratyush c597de6a1d topic_mentions: Rename wildcard_mentioned to stream_wildcard_mentioned.
Rename the existing 'wildcard_mentioned' flag to
'stream_wildcard_mentioned'.

The 'wildcard_mentioned' flag is deprecated and exists for
backwards compatibility.

We have two separate flags for stream and topic wildcard mentions,
i.e., 'stream_wildcard_mentioned' and 'topic_wildcard_mentioned',
respectively.

* stream wildcard mentions: `@all`, `@everyone`, and `@stream`
* topic wildcard mentions: `@topic`

The `wildcard_mentioned` flag is included in the events and
API response if either `stream_wildcard_mentioned` or
`topic_wildcard_mentioned` is set.

Sahil Batra bb15b2d708 users: Send "update" events when deactivating or reactivating users.
We now send "realm_user/update" (and "realm_bot/update" for bots)
events with "is_active" field when deactivating and reactivating
users, including bots.

We would want to use "remove" event for a user losing access
to another user for #10970, so it is better to use "update"
event for deactivation as we only update "is_active" field
in the user objects and the clients still have the data for
deactivated users.

Previously, we used to send "add" event for reactivation along
with complete user objects, but clients should have the data
for deactivated users as well, so an "update" event is enough
like we do when deactivating users.

Prakhar Pratyush 02f3f73b0c recipient_info: Include 'sender_id' in 'topic_participant_user_ids'.
This commit includes the message's sender id in the
'topic_participant_user_ids' set.

The 'participants_for_topic' function doesn't include the sender_id,
if the user is sending their first message in the topic, because
'participants_for_topic' queries the 'Message' table, but the message
is actually sent at a later stage in the codepath, resulting in
missing the sender_id in this case.

This is needed to set the 'wildcard_mentioned' flag for the sender's
user message in the case of topic wildcard mentions.

This doesn't lead to sending email and push notifications to the
sender because we have a check to skip notifications if the user
to receive notifications is the sender itself.

This should have been included in c0c30bc.

Tim Abbott c6fe799369 i18n: Fix default language for users created via API/LDAP.
This fixes a regression introduced in
9954db4b59, where the realm's default
language would be ignored for users created via API/LDAP/SAML,
resulting in all such users having English as their default language.

The API/LDAP/SAML account creation code paths don't have a request,
and thus cannot pull default language from the user's browser.

We have the `realm.default_language` field intended for this use case,
but it was not being passed through the system.

Rather than pass `realm.default_language` through from each caller, we
make the low-level user creation code set this field, as that seems
more robust to the creation of future callers.

Lauryn Menard 91b40a45fe demo-orgs: Add email and password process for demo organization owners.
Creates process for demo organization owners to add an email address

Uses the same flow as changing an email (via user settings) at the
beginning, but then sends a different email template to the user
for the email confirmation process.

We also encourage users to set their full name field in the modal for
adding an email in a demo organization. We disable the submit button
on the form if either input is empty, email or full name.

When the user clicks the 'confirm and set password' button in the
email sent to confirm the email address sent via the form, their
email is updated via confirm_email_change, but the user is redirected
to the reset password page for their account (instead of the page for
confirming an email change has happened).

Once the user successfully sets a password, then they will be
prompted to log in with their newly configured email and password.

Mateusz Mandera c908b518ef CVE-2023-32678: Prevent unauthorized editing/deletion in priv streams.
Users who used to be subscribed to a private stream and have been
removed from it since retain the ability to edit messages/topics, and
delete messages that they used to have access to, if other relevant
organization permissions allow these actions. For example, a user may be
able to edit or delete their old messages they posted in such a private
stream. An administrator will be able to delete old messages (that they
had access to) from the private stream.

We fix this by fixing the logic in has_message_access (which lies at the
core of our message access checks - access_message() and
bulk_access_messages())
to not rely on only a UserMessage row for checking access but also
verify stream type and subscription status.
2023-08-25 14:10:27 -04:00
Zixuan James Li a081428ad2 user_groups: Make locks required for updating user group memberships.
**Background**

User groups are expected to comply with the DAG constraint for the
many-to-many inter-group membership. The check for this constraint has
to be performed recursively so that we can find all direct and indirect
subgroups of the user group to be added.

This kind of check is vulnerable to phantom reads which is possible at
the default read committed isolation level because we cannot guarantee
that the check is still valid when we are adding the subgroups to the
user group.

**Solution**

To avoid having another transaction concurrently update one of the
to-be-subgroup after the recursive check is done, and before the subgroup
is added, we use SELECT FOR UPDATE to lock the user group rows.

The lock needs to be acquired before a group membership change is about
to occur before any check has been conducted.

Suppose that we are adding subgroup B to supergroup A, the locking protocol
is specified as follows:

1. Acquire a lock for B and all its direct and indirect subgroups.
2. Acquire a lock for A.

For the removal of user groups, we acquire a lock for the user group to
be removed with all its direct and indirect subgroups. This is the special
case A=B, which is still complaint with the protocol.

**Error handling**

We currently rely on Postgres' deadlock detection to abort transactions
and show an error for the users. In the future, we might need some
recovery mechanism or at least better error handling.

**Notes**

An important note is that we need to reuse the recursive CTE query that
finds the direct and indirect subgroups when applying the lock on the
rows. And the lock needs to be acquired the same way for the addition and
removal of direct subgroups.

User membership change (as opposed to user group membership) is not
affected. Read-only queries aren't either. The locks only protect
critical regions where the user group dependency graph might violate
the DAG constraint, where users are not participating.

**Testing**

We implement a transaction test case targeting some typical scenarios
when an internal server error is expected to happen (this means that the
user group view makes the correct decision to abort the transaction when
something goes wrong with locks).

To achieve this, we add a development view intended only for unit tests.
It has a global BARRIER that can be shared across threads, so that we
can synchronize them to consistently reproduce certain potential race
conditions prevented by the database locks.

The transaction test case lanuches pairs of threads initiating possibly
conflicting requests at the same time. The tests are set up such that exactly N
of them are expected to succeed with a certain error message (while we don't
know each one).

**Security notes**

get_recursive_subgroups_for_groups will no longer fetch user groups from
other realms. As a result, trying to add/remove a subgroup from another
realm results in a UserGroup not found error response.

We also implement subgroup-specific checks in has_user_group_access to
keep permission managing in a single place. Do note that the API
currently don't have a way to violate that check because we are only
checking the realm ID now.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Prakhar Pratyush 665f491f22 message_edit: Fix wildcard_mentioned flag set for all user-messages.
Earlier, for topic wildcard mentions, the 'wildcard_mentioned'
flag was set for all the user-messages. (similar to stream wildcard
mention).

The flag should be set for the topic participants only.

The bug was introduced in 4c9d26c.

Prakhar Pratyush 379a08eb1e message_send: Fix wildcard_mentioned flag unset for few participants.
For topic wildcard mentions, the 'wildcard_mentioned' flag is set
for those user messages having 'user_profile_id' in
'topic_participant_user_ids', i.e. all topic participants.

Earlier, the flag was set if the 'user_profile_id' exists in
'all_topic_wildcard_mention_user_ids'.
'all_topic_wildcard_mention_user_ids' contains the ids of those
users who are topic participants and have enabled notifications
for '@topic' mentions.

The earlier approach was incorrect, as it would set the
'wildcard_mentioned' flag only for those topic participants
who have enabled the notifications for '@topic' mention instead
of setting the flag for all the topic participants.

The bug was introduced in 4c9d26c.

Zixuan James Li 37660dd0e7 linkifier: Support reordering linkifiers.
This adds API support to reorder linkifiers and makes sure that the
returned lists of linkifiers from `GET /events`, `POST /register`, and
`GET /realm/linkifiers` are always sorted with the order that they
should processed when rendering linkifiers.

We set the new `order` field to the ID with the migration. This
preserves the order of the existing linkifiers.

New linkifiers added will always be ordered the last. When reordering,
the `order` field of all linkifiers in the same realm is updated, in
a manner similar to how we implement ordering for
`custom_profile_fields`.

Prakhar Pratyush c4e4737cc6 notification_trigger: Rename `private_message` to `direct_message`.
This commit renames the 'PRIVATE_MESSAGE' attribute of the
'NotificationTriggers' class to 'DIRECT_MESSAGE'.

Custom migration to update the existing value in the database.

It includes 'TODO/compatibility' code to support the old
notification trigger value 'private_message' in the
push notification queue during the Zulip server upgrades.

Earlier 'private_message' was one of the possible values for the
'trigger' property of the '[`POST /zulip-outgoing-webhook`]' response;
Update the docs to reflect the change in the above-mentioned trigger
value.

Sahil Batra ae72151ec1 streams: Pass stream_weekly_traffic field in stream objects.
This commit adds code to pass stream traffic data using
the "stream_weekly_traffic" field in stream objects.

We already include the traffic data in Subscription objects,
but the traffic data does not depend on the user to stream
relationship and is stream-only information, so it's better
to include it in Stream objects. We may remove the traffic
data and other stream information fields for Subscription
objects in future.

This will help clients to correctly display the stream
traffic data in case where client receives a stream
creation event and no subscription event, for an already
existing stream which the user did not have access to before.

Alex Vandiver b67108c8c6 retention: Prevent deletion of partially-archived messages.
Previously, this code:
```python3
old_archived_attachments = ArchivedAttachment.objects.annotate(
    has_other_messages=Exists(
        Attachment.objects.filter(id=OuterRef("id"))
        .exclude(messages=None)
        .exclude(scheduled_messages=None)
    )
).filter(messages=None, create_time__lt=delta_weeks_ago, has_other_messages=False)
```

...protected from removal any ArchivedAttachment objects where there
was an Attachment which had _both_ a message _and_ a scheduled
message, instead of _either_ a message _or_ a scheduled message.
Since files are removed from disk when the ArchivedAttachment rows are
deleted, this meant that if an upload was referenced in two messages,
and one was deleted, the file was permanently deleted when the
ArchivedMessage and ArchivedAttachment were cleaned up, despite being
still referenced in live Messages and Attachments.

Switch from `.exclude(messages=None).exclude(scheduled_messages=None)`
to `.exclude(messages=None, scheduled_messages=None)` which "OR"s
those conditions appropriately.

Pull the relevant test into its own file, and expand it significantly
to cover this, and other, corner cases.

of user_group whose members can mention the group.

This commit renames this field to `can_mention_group`.
