From 9cc63f8bcd560c760d0b12e15bba8f81c86237cf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 14 Aug 2026 15:43:51 -0700 Subject: Merge branches 'expcb.2026.07.24a', 'misc.2026.07.30a', 'rcu-tasks.2026.07.30a', 'srcu.2026.08.11a' and 'torture.2026.08.14a' into HEAD Changes: Make expedited grace periods expedite normal RCU callbacks Miscellaneous fixes: * Improve diagnostic output with character task states. * Mark accesses to inform KCSAN of concurrency design. * Move from kmalloc() to kmalloc_obj(). * Documentation updates. * Improve handling of RCU deferred quiescent states. * Clean up unused function arguments and structure fields. * Reduce show_rcu_gp_kthreads() stack space. Tasks RCU updates: * Clean up after SRCU re-implementation of Tasks Trace RCU. * Mark accesses to inform KCSAN of concurrency design. * Add ->lazy_timer status to diagnostic output. * Remove an unnecessary memory barrier. * Fix a data race, courtesy of KCSAN. * Documentation updates. * Convert cond_resched_tasks_rcu_qs() from macro to static inline function. SRCU updates: * Add Rust helpers for SRCU. * Avoid losing queued work at cleanup_srcu_struct() time. Torture-test updates: * Preparation work for immediate RCU priority deboosting. * Test RCU readers from real interrupt handlers (as opposed to softirq). * Simplify code through use of cpumask_next_wrap(). * Improve diagnostic output with character task states. * Add rcutorture.nwriters parameter to allow lightweight stall testing, and rcutorture.stall_only to make doing so easier. * Test an RCU Tasks Trace grace period implying an RCU grace period. * Make RCU Tasks Trace torturing track reader batches. * Fix a data race, courtesy of KCSAN. * Plug a shuffle_tmp_mask memory leak on kthread spawn failure. --- include/net/llc_if.h | 63 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 include/net/llc_if.h (limited to 'include/net/llc_if.h') diff --git a/include/net/llc_if.h b/include/net/llc_if.h new file mode 100644 index 000000000..a33325961 --- /dev/null +++ b/include/net/llc_if.h @@ -0,0 +1,63 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef LLC_IF_H +#define LLC_IF_H +/* + * Copyright (c) 1997 by Procom Technology,Inc. + * 2001 by Arnaldo Carvalho de Melo + */ +/* Defines LLC interface to network layer */ +/* Available primitives */ +#include +#include +#include +#include +#include + +#define LLC_DATAUNIT_PRIM 1 +#define LLC_CONN_PRIM 2 +#define LLC_DATA_PRIM 3 +#define LLC_DISC_PRIM 4 +#define LLC_RESET_PRIM 5 +#define LLC_FLOWCONTROL_PRIM 6 /* Not supported at this time */ +#define LLC_DISABLE_PRIM 7 +#define LLC_XID_PRIM 8 +#define LLC_TEST_PRIM 9 +#define LLC_SAP_ACTIVATION 10 +#define LLC_SAP_DEACTIVATION 11 + +#define LLC_NBR_PRIMITIVES 11 + +#define LLC_IND 1 +#define LLC_CONFIRM 2 + +/* Primitive type */ +#define LLC_PRIM_TYPE_REQ 1 +#define LLC_PRIM_TYPE_IND 2 +#define LLC_PRIM_TYPE_RESP 3 +#define LLC_PRIM_TYPE_CONFIRM 4 + +/* Reset reasons, remote entity or local LLC */ +#define LLC_RESET_REASON_REMOTE 1 +#define LLC_RESET_REASON_LOCAL 2 + +/* Disconnect reasons */ +#define LLC_DISC_REASON_RX_DM_RSP_PDU 0 +#define LLC_DISC_REASON_RX_DISC_CMD_PDU 1 +#define LLC_DISC_REASON_ACK_TMR_EXP 2 + +/* Confirm reasons */ +#define LLC_STATUS_CONN 0 /* connect confirm & reset confirm */ +#define LLC_STATUS_DISC 1 /* connect confirm & reset confirm */ +#define LLC_STATUS_FAILED 2 /* connect confirm & reset confirm */ +#define LLC_STATUS_IMPOSSIBLE 3 /* connect confirm */ +#define LLC_STATUS_RECEIVED 4 /* data conn */ +#define LLC_STATUS_REMOTE_BUSY 5 /* data conn */ +#define LLC_STATUS_REFUSE 6 /* data conn */ +#define LLC_STATUS_CONFLICT 7 /* disconnect conn */ +#define LLC_STATUS_RESET_DONE 8 /* */ + +int llc_establish_connection(struct sock *sk, const u8 *lmac, u8 *dmac, + u8 dsap); +int llc_build_and_send_pkt(struct sock *sk, struct sk_buff *skb); +int llc_send_disc(struct sock *sk); +#endif /* LLC_IF_H */ -- cgit v1.3.1
