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. --- drivers/net/wireguard/generated/netlink.c | 73 +++++++++++++++++++++++++++++++ drivers/net/wireguard/generated/netlink.h | 30 +++++++++++++ 2 files changed, 103 insertions(+) create mode 100644 drivers/net/wireguard/generated/netlink.c create mode 100644 drivers/net/wireguard/generated/netlink.h (limited to 'drivers/net/wireguard/generated') diff --git a/drivers/net/wireguard/generated/netlink.c b/drivers/net/wireguard/generated/netlink.c new file mode 100644 index 000000000..3ef8c2990 --- /dev/null +++ b/drivers/net/wireguard/generated/netlink.c @@ -0,0 +1,73 @@ +// SPDX-License-Identifier: ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) +/* Do not edit directly, auto-generated from: */ +/* Documentation/netlink/specs/wireguard.yaml */ +/* YNL-GEN kernel source */ +/* YNL-ARG --function-prefix wg */ +/* To regenerate run: tools/net/ynl/ynl-regen.sh */ + +#include +#include + +#include "netlink.h" + +#include +#include + +/* Common nested types */ +const struct nla_policy wireguard_wgallowedip_nl_policy[WGALLOWEDIP_A_FLAGS + 1] = { + [WGALLOWEDIP_A_FAMILY] = { .type = NLA_U16, }, + [WGALLOWEDIP_A_IPADDR] = NLA_POLICY_MIN_LEN(4), + [WGALLOWEDIP_A_CIDR_MASK] = { .type = NLA_U8, }, + [WGALLOWEDIP_A_FLAGS] = NLA_POLICY_MASK(NLA_U32, 0x1), +};
