Subject: [PATCH net-next v11 07/15] quic: add connection id management
Date: Tue, 24 Mar 2026 23:47:12 -0400 [thread overview]
Message-ID: <18c72217e52fbdca9971a81ce5aba21096319ec9.1774410440.git.lucien.xin@gmail.com> (raw)
In-Reply-To: <cover.1774410440.git.lucien.xin@gmail.com>
This patch introduces 'struct quic_conn_id_set' for managing Connection
IDs (CIDs), which are represented by 'struct quic_source_conn_id'
and 'struct quic_dest_conn_id'.
It provides helpers to add and remove CIDs from the set, and handles
insertion of source CIDs into the global connection ID hash table
when necessary.
- quic_conn_id_add(): Add a new Connection ID to the set, and inserts
it to conn_id hash table if it is a source conn_id.
- quic_conn_id_remove(): Remove connection IDs the set with sequence
numbers less than or equal to a number.
It also adds utilities to look up CIDs by value or sequence number,
search the global hash table for incoming packets, and check for
stateless reset tokens among destination CIDs. These functions are
essential for RX path connection lookup and stateless reset processing.
- quic_conn_id_find(): Find a Connection ID in the set by seq number.
- quic_conn_id_lookup(): Lookup a Connection ID from global hash table
using the ID value, typically used for socket lookup on the RX path.
- quic_conn_id_token_exists(): Check if a stateless reset token exists
in any dest Connection ID (used during stateless reset processing).
Note source/dest conn_id set is per socket, the operations on it are
always protected by the sock lock.

---
v3:
- Clarify in changelog that conn_id set is always protected by sock lock
(suggested by Paolo).
- Adjust global source conn_id hashtable operations for the new hashtable
type.
v4:
- Replace struct hlist_node with hlist_nulls_node for the node in
struct quic_source_conn_id to support lockless lookup.
v7:
- Break the loop earlier if common->number > number in
quic_conn_id_remove/find() (suggested by Paolo).
- Add a comment in quic_conn_id_first_number().
v8:
- Add a comment to quic_conn_id_remove() clarifying that the ID number
must be smaller than the sequence number of the last ID in the set.
v11:
- Note for AI review: each id_set contains at most 8 connection IDs, so
using an RB-tree for faster lookup is unnecessary.
- Set maximum line length to 80 characters.
- Add a check for number in quic_conn_id_remove().
