Subject: [PATCH net-next 1/3] llc: move the type 2 sockets out of tree
Date: Mon, 28 Sep 2026 12:07:58 -0700 [thread overview]
Message-ID: <20260928190800.2521749-2-kuba@kernel.org> (raw)
In-Reply-To: <20260928190800.2521749-1-kuba@kernel.org>
802.2 LLC is only used in tree by protocols which need the
connectionless type 1 subset: STP, which carries the bridge's BPDUs,
GARP, which sends its own UI PDUs, and SNAP. The llc2 module on top of
the core - the type 2 connection state machine, the type 1 SAP state
machine, the station component and the PF_LLC socket family - has no
in-kernel users and nobody who can test it; what we get instead is a
slow trickle of drive-by fixes.
There was a recent patch from Ernestas Kulik indicating potential
real life use, but it was new/experimental and that person is
not responding to off-list pings.
Let LLC2 follow AX.25, hamradio and AppleTalk out of the Linux tree.
We will maintain the code at: github.com/linux-netdev/mod-orphan
for anyone interested in playing with it.
PF_LLC goes in full, both the class two SOCK_STREAM and the class one
SOCK_DGRAM half, and so do /proc/net/llc/ and /proc/sys/net/llc/. Note
that the kernel also stops answering XID and TEST commands, addressed
to a SAP or to the station - those are type 1, but they lived in the
module, and they got answered whether or not any socket was open.
Nothing in tree asks for them; what the core keeps is SAP registration
and the UI path the in-tree users need.
Retain the uAPI for now, like we did for AppleTalk. Only the socket ABI
half of it is vestigial: STP, GARP, the bridge and openvswitch use the
SAP numbers it defines. Cleaning up what the core no longer needs
follows in the next patch.

- * llc_c_ev.c - Connection component state transition event qualifiers
- *
- * A 'state' consists of a number of possible event matching functions,
- * the actions associated with each being executed when that event is
- * matched; a 'state machine' accepts events in a serial fashion from an
- * event queue. Each event is passed to each successive event matching
- * function until a match is made (the event matching function returns
- * success, or '0') or the list of event matching functions is exhausted.
- * If a match is made, the actions associated with the event are executed
- * and the state is changed to that event's transition state. Before some
- * events are recognized, even after a match has been made, a certain
- * number of 'event qualifier' functions must also be executed. If these
- * all execute successfully, then the event is finally executed.
- *
- * These event functions must return 0 for success, to show a matched
- * event, of 1 if the event does not match. Event qualifier functions
- * must return a 0 for success or a non-zero for failure. Each function
- * is simply responsible for verifying one single thing and returning
- * either a success or failure.
- *
- * All of followed event functions are described in 802.2 LLC Protocol
- * standard document except two functions that we added that will explain
- * in their comments, at below.
