Subject: [PATCH 08/58] Rate limiting changes (#2519)

* Rate limiting changes

This makes the following changes:

* For logged in users, the rate limiting now applies to the device session rather than the remote IP address;
* For non-logged in users, the rate limiting continues to apply to remote address as it does today;
* It is now possible to add user IDs to the `exempt_user_ids` option under `rate_limiting` to exclude bots from rate limiting;
* Admin and appservice users are now exempt from rate limiting by default.

* Fix build with media API

 # Changelog
 
+## Dendrite 0.8.8 (2022-06-09)
+
+### Features
+
+* The performance of state resolution has been increased significantly for larger rooms
+* A number of changes have been made to rate limiting:
+  * Logged in users will now be rate-limited on a per-session basis rather than by remote IP
+  * Rate limiting no longer applies to admin or appservice users
+  * It is now possible to configure additional users that are exempt from rate limiting using the `exempt_user_ids` option in the `rate_limiting` section of the Dendrite config
+* Setting state is now idempotent via the client API state endpoints
+
+### Fixes
+
+* Room upgrades now properly propagate tombstone events to remote servers
+* Room upgrades will no longer send tombstone events if creating the upgraded room fails
+* A crash has been fixed when evaluating restricted room joins
+

+# Next steps
+
+Now that you have Dendrite running, the following tweaks will improve the reliability
+of your installation.
+
+## File descriptor limit
+
+Most platforms have a limit on how many file descriptors a single process can open. All
+connections made by Dendrite consume file descriptors — this includes database connections
+and network requests to remote homeservers. When participating in large federated rooms
+where Dendrite must talk to many remote servers, it is often very easy to exhaust default
+limits which are quite low.
+
+We currently recommend setting the file descriptor limit to 65535 to avoid such
+issues. Dendrite will log immediately after startup if the file descriptor limit is too low:
+
+```
+level=warning msg="IMPORTANT: Process file descriptor limit is currently 1024, it is recommended to raise the limit for Dendrite to at least 65535 to avoid issues"
+```
+
+UNIX systems have two limits: a hard limit and a soft limit. You can view the soft limit
+by running `ulimit -Sn` and the hard limit with `ulimit -Hn`:
+
+```
+$ ulimit -Hn
+1048576
+
+$ ulimit -Sn
+1024
+```
+
+Increase the soft limit before starting Dendrite:
+
+```
+ulimit -Sn 65535
+```
+
+The log line at startup should no longer appear if the limit is sufficient.
+
+If you are running under a systemd service, you can instead add `LimitNOFILE=65535` option
+to the `[Service]` section of your service unit file.
+
+## DNS caching
+
+Dendrite has a built-in DNS cache which significantly reduces the load that Dendrite will
+place on your DNS resolver. This may also speed up outbound federation.
+
+Consider enabling the DNS cache by modifying the `global` section of your configuration file:
+
+```
+  dns_cache:
+    enabled: true
+    cache_size: 4096
+    cache_lifetime: 600s
+```
+
+## Time synchronisation
+
+Matrix relies heavily on TLS which requires the system time to be correct. If the clock
+drifts then you may find that federation no works reliably (or at all) and clients may
+struggle to connect to your Dendrite server.
+
+Ensure that the time is synchronised on your system by enabling NTP sync.

Subject: [PATCH 28/58] Verify that the user ID for registration matches the
 spec, and the auth data (#10)

* Blacklist some sytest tests that are failing in our environment

* Commenting out test that isn't reliably passing or failing, probably a race

* refresh latest dendrite main

* pull latest from dendrite-fork subtree

* refresh latest dendrite main

* pull dendrite subtree and resolve merge conflicts

* check that userID matches the signed message

* verify that the user ID for registration is CAIP-10 compliant and MXID compliant

* removed space

 # Changelog
 
+## Dendrite 0.8.9 (2022-07-01)
+
+### Features
+
+* Incoming device list updates over federation are now queued in JetStream for processing so that they will no longer block incoming federation transactions and should never end up dropped, which will hopefully help E2EE reliability
+* The `/context` endpoint now returns `"start"` and `"end"` parameters to allow pagination from a context call
+* The `/messages` endpoint will no longer return `"end"` when there are no more messages remaining
+* Deactivated user accounts will now leave all rooms automatically
+* New admin endpoint `/_dendrite/admin/evacuateUser/{userID}` has been added for forcing a local user to leave all joined rooms
+* Dendrite will now automatically attempt to raise the file descriptor limit at startup if it is too low
+
+### Fixes
+
+* A rare crash when retrieving remote device lists has been fixed
+* Fixes a bug where events were not redacted properly over federation
+* The `/invite` endpoints will now return an error instead of silently proceeding if the user ID is obviously malformed
+
 ## Dendrite 0.8.8 (2022-06-09)

Subject: [PATCH 42/58] Implement EIP-4361 sign in with Ethereum (#5)

* Blacklist some sytest tests that are failing in our environment

* Commenting out test that isn't reliably passing or failing, probably a race

* refresh latest dendrite main

* refresh latest dendrite main

* dendrite implementation of eip-4361

* simplify nonce generation

+# Troubleshooting
+
+If your Dendrite installation is acting strangely, there are a few things you should
+check before seeking help.
+
+## 1. Logs
+
+Dendrite, by default, will log all warnings and errors to stdout, in addition to any
+other locations configured in the `dendrite.yaml` configuration file. Often there will
+be clues in the logs.
+
+You can increase this log level to the more verbose `debug` level if necessary by adding
+this to the config and restarting Dendrite:
+
+```
+logging:
+- type: std
+  level: debug
+```
+
+Look specifically for lines that contain `level=error` or `level=warning`.
+
+## 2. Federation tester
+
+If you are experiencing problems federating with other homeservers, you should check
+that the [Federation Tester](https://federationtester.matrix.org) is passing for your
+server.
+
+Common reasons that it may not pass include:
+
+1. Incorrect DNS configuration;
+2. Misconfigured DNS SRV entries or well-known files;
+3. Invalid TLS/SSL certificates;
+4. Reverse proxy configuration issues (if applicable).
+
+Correct any errors if shown and re-run the federation tester to check the results.
+
+## 3. System time
+
+Matrix relies heavily on TLS which requires the system time to be correct. If the clock
+drifts then you may find that federation no works reliably (or at all) and clients may
+struggle to connect to your Dendrite server.
+
+Ensure that your system time is correct and consider syncing to a reliable NTP source.
+
+## 4. Database connections
+
+If you are using the PostgreSQL database, you should ensure that Dendrite's configured
+number of database connections does not exceed the maximum allowed by PostgreSQL.
+
+Open your `postgresql.conf` configuration file and check the value of `max_connections`
+(which is typically `100` by default). Then open your `dendrite.yaml` configuration file
+and ensure that:
+
+1. If you are using the `global.database` section, that `max_open_conns` does not exceed
+   that number;
+2. If you are **not** using the `global.database` section, that the sum total of all
+   `max_open_conns` across all `database` blocks does not exceed that number.
+
+## 5. File descriptors
+
+Dendrite requires a sufficient number of file descriptors for every connection it makes
+to a remote server, every connection to the database engine and every file it is reading
+or writing to at a given time (media, logs etc). We recommend ensuring that the limit is
+no lower than 65535 for Dendrite.
+
+Dendrite will check at startup if there are a sufficient number of available descriptors.
+If there aren't, you will see a log lines like this:
+
+```
+level=warning msg="IMPORTANT: Process file descriptor limit is currently 65535, it is recommended to raise the limit for Dendrite to at least 65535 to avoid issues"
+```
+
+Follow the [Optimisation](../installation/10_optimisation.md) instructions to correct the
+available number of file descriptors.

Subject: [PATCH 57/58] /hierarchy - return public and knockable rooms for
 authed users

When requesting the room hierarchy with an authenticated user, return public and knockable rooms.

According to the spec, https://github.com/matrix-org/matrix-spec-proposals/blob/main/proposals/2946-spaces-summary.md

```
Any child room that the user is joined or is potentially joinable is included in the response.
```

This is currently not the case. See discussion here: https://matrix.to/#/!NasysSDfxKxZBzJJoE:matrix.org/$t2Csj-6y1PVsn8GOnFZfXzeQW13NfqvrFCxB-XI_uhA?via=matrix.org&via=libera.chat&via=element.io and here: https://matrix.to/#/!NasysSDfxKxZBzJJoE:matrix.org/$EHp1x1DY7tnYZtx_PVEb-sKB9lmJajqHx2uGlhrRh6k?via=matrix.org&via=libera.chat&via=element.io

Test Plan:
create and register clients bob and alice
have bob create a public space
have bob create a public room parented to the space
have alice join the space(room)
have alice sync the space
expect alice to see two rooms in the space hierarchy, the space and the child room
