  "title": "net/rds: clear cp_flags bits individually in rds_conn_path_reset()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net/rds: clear cp_flags bits individually in rds_conn_path_reset()  rds_conn_path_reset() wipes the whole flag word with a plain cp-\u003Ecp_flags = 0 store.  Every other accessor of that word uses atomic bitops, and some of them can run concurrently with the reset: RDS_LL_SEND_FULL is set from rds_send_xmit() and cleared from the transport completion paths, neither of which holds anything that excludes the shutdown worker.  A plain store racing an atomic read-modify-write on the same word is a data race, and whichever side loses has its update silently discarded.  Clear the two bits the reset is actually responsible for instead. RDS_IN_XMIT and RDS_RECV_REFILL need no store at all here: they belong to the caller, rds_conn_shutdown(), which waits for both to be clear before calling the transport shutdown and this reset.  This also gives every bit in cp_flags a single well-defined writer discipline, which the following patches rely on when they turn RDS_IN_XMIT and RDS_RECV_REFILL into bit locks held across the teardown: a blanket store mid-teardown would destroy lock ownership that an atomic clear preserves.  Oracle UEK carries the same conversion (\u0022net/rds: Preserve essential connection state flags\u0022), motivated by its asynchronous shutdown state machine, whose progress and destroy flags must survive the reset.  UEK\u0027s variant also clears RDS_IN_XMIT and RDS_RECV_REFILL because there the reset runs as the final step of a teardown that owns both bits, making those clears its unlock.  Upstream that release belongs in rds_conn_shutdown(): once a later patch in this series turns the two bits into locks held across the teardown, ending ownership needs release semantics and a wake-up that a plain clear inside the reset would not provide.  Based on Oracle UEK commit \u0022net/rds: Preserve essential connection state flags\u0022 by Gerd Rausch.",
