LLC2 sockets are admin-only already. We have been getting a trickle
of LLM-driven fixes for these, even tho we don't know of any active
user. The code is so bad the LLM fixes just turn into a never ending
stream of revisions and follow ups as fixing one condition reveals
5 more bugs. Let's move this code out of tree.
The series itself is LLM generated, the LLM was also nice enough
to generates some tests and validate that the OOT module actually
works.

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.

As far as I remember the only historic use of LLC2 was netbeui (which I've probably misspelled). That was really replaced by NetBios of TCP. So we are in the age of 8-bit ISA ethernet cards that stood no chance of receiving the 15 back-to-back ethernet frames they issued credit for. Oh, and another stunningly bad ISA card that sometimes failed to indicate there was a frame in its rx fifo (for pio reads) until the following frame arrived (even the fifo byte count was wrong). I can't remember exactly why that completely broke llc2.

* [PATCH net-next 2/3] llc: strip the leftovers of the llc2 removal 2026-09-28 19:07 [PATCH net-next 0/3] net: move the type 2 sockets out of tree Jakub Kicinski 2026-09-28 19:07 ` [PATCH net-next 1/3] llc: " Jakub Kicinski @ 2026-09-28 19:07 ` Jakub Kicinski 2026-09-28 19:08 ` [PATCH net-next 3/3] net: drop unused LLC-related includes Jakub Kicinski ` (2 subsequent siblings) 4 siblings, 0 replies; 8+ messages in thread From: Jakub Kicinski @ 2026-09-28 19:07 UTC (permalink / raw) To: davem Cc: netdev, edumazet, pabeni, andrew+netdev, horms, kernel, chenhuacai, tsbogend, deller, razor, idosch, aconole, ardb, tim.bird, loongarch, linux-mips, linux-parisc, Jakub Kicinski Nothing in tree registers the type 1 / type 2 packet handlers or the station handler any more, and nothing looks at the socket hashes hanging off struct llc_sap. The two SAPs opened in tree - SNAP, and STP for the bridge's BPDUs and GARP's PDUs - receive through the per-SAP rcv_func(), so llc_rcv() boils down to a SAP lookup and a call. llc_sap_list becomes static and five exports go away with all this; the llc2 module out of tree has been reworked to open its own SAPs. Frames with a NULL DSAP used to be handed to the station handler before the SAP lookup. They take the normal path now, meaning they get dropped unless something registers SAP 0. struct llc_sap is down to 48 bytes on 64-bit from over a kilobyte, which also moves its GFP_ATOMIC allocation from kmalloc-2k to kmalloc-64. The two 64-entry socket hashes are the bulk of it, and the address it carried is now just the SAP number - nothing has read the MAC half since the socket layer left. llc_pdu.h keeps only what its remaining users need, plus LLC_PDU_RSP to document the one argument which can take it. That takes out the type 2 (I and S format, FRMR) definitions, the XID and TEST builders with their constants - the kernel neither sends nor answers either any more - the SAP address defines, the field accessors, and the prototypes of the llc_pdu.c helpers which went out of tree with the rest of LLC2. With the I and S formats gone llc_pdu_header_init() has one PDU type left, so drop the argument.
