Subject: [PATCH v2 00/13] Manage more flow related things from generic flow code
Date: Wed, 20 Dec 2023 18:08:55 +1100 [thread overview]
Message-ID: <20231220070908.2506277-1-david@gibson.dropbear.id.au> (raw)
There are a number of things that are more-or-less general to flows
which are still explicitly handled in tcp.c and tcp_splice.c including
allocation and freeing of flow entries, and dispatch of deferred and
timer functions.
Even without adding more fields to the common flow structure, we can
handle a number of these in a more flow-centric way.
Unlike v1 this version is based on the hash table rework series.
Changes since v1:
* Store the timestamp of last flow timers run in a global, rather
than a ctx field
* Rebased on the TCP hash table rework
* Add patches 9..13/13 with changes to allocation and freeing of flow
entries.
David Gibson (13):
flow: Make flow_table.h #include the protocol specific headers it
needs
treewide: Standardise on 'now' for current timestamp variables
tcp, tcp_splice: Remove redundant handling from tcp_timer()
tcp, tcp_splice: Move per-type cleanup logic into per-type helpers
flow, tcp: Add flow-centric dispatch for deferred flow handling
flow, tcp: Add handling for per-flow timers
epoll: Better handling of number of epoll types
tcp, tcp_splice: Avoid double layered dispatch for connected TCP
sockets
flow: Move flow_log_() to near top of flow.c
flow: Move flow_count from context structure to a global
flow: Abstract helpers for allocating new flows
flow: Enforce that freeing of closed flows must happen in deferred
handlers
flow: Avoid moving flow entries to compact table
