Previous implementation would disconnect _all_ clients when running `ACL LOAD`, which wasn't very useful. This change brings the behavior in line with that of `ACL SETUSER`, `ACL DELUSER`, in that only clients whose user is deleted or clients subscribed to channels which they no longer have access to will be disconnected. --------- Co-authored-by:

For backwards compatibility in 6.x, channels default permission was set to `allchannels` however with 7.0, we should modify it and the default value should be `resetchannels` for better security posture. Also, with selectors in ACL, a client doesn't have to set channel rules everytime and by default the value will be `resetchannels`. Before this change ``` 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 127.0.0.1:6379> acl setuser hp on nopass +@all ~* OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* &* +@all" 127.0.0.1:6379> acl setuser hp1 on nopass -@all (%R~sales*) OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* &* +@all" 3) "user hp1 on nopass &* -@all (%R~sales* &* -@all)" ``` After this change ``` 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 127.0.0.1:6379> acl setuser hp on nopass +@all ~* OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* resetchannels +@all" 127.0.0.1:6379> acl setuser hp1 on nopass -@all (%R~sales*) OK 127.0.0.1:6379> acl list 1) "user default on nopass ~* &* +@all" 2) "user hp on nopass ~* resetchannels +@all" 3) "user hp1 on nopass resetchannels -@all (%R~sales* resetchannels -@all)" ```

Fix "default" and overwritten / reset users will not have pubsub channels permissions by default. (#8723) Background: Redis 6.2 added ACL control for pubsub channels (#7993), which were supposed to be permissive by default to retain compatibility with redis 6.0 ACL. But due to a bug, only newly created users got this `acl-pubsub-default` applied, while overwritten (updated) users got reset to `resetchannels` (denied). Since the "default" user exists before loading the config file, any ACL change to it, results in an update / overwrite. So when a "default" user is loaded from config file or include ACL file with no channels related rules, the user will not have any permissions to any channels. But other users will have default permissions to any channels. When upgraded from 6.0 with config rewrite, this will lead to "default" user channels permissions lost. When users are loaded from include file, then call "acl load", users will also lost channels permissions. Similarly, the `reset` ACL rule, would have reset the user to be denied access to any channels, ignoring `acl-pubsub-default` and breaking compatibility with redis 6.0. The implication of this fix is that it regains compatibility with redis 6.0, but breaks compatibility with redis 6.2.0 and 2.0.1. e.g. after the upgrade, the default user will regain access to pubsub channels. Other changes: Additionally this commit rename server.acl_pubusub_default to server.acl_pubsub_default and fix typo in acl tests.
