Subject: Re: [PATCH net] net/rds: An rds_sock is added too early to the
 hash table

> In rds_bind(), an rds_sock is added to the RDS bind hash table before
> rs_transport is set.  This means that the socket can be found by the
> receive code path when rs_transport is NULL.  And the receive code
> path de-references rs_transport for congestion update check.  This can
> cause a panic.  An rds_sock should not be added to the bind hash table
> before all the needed fields are set.
