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. --- lib/audit.c | 89 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 lib/audit.c (limited to 'lib/audit.c') diff --git a/lib/audit.c b/lib/audit.c new file mode 100644 index 000000000..bc07fbd3a --- /dev/null +++ b/lib/audit.c @@ -0,0 +1,89 @@ +// SPDX-License-Identifier: GPL-2.0 +#include +#include +#include +#include + +static unsigned dir_class[] = { +#include +~0U +}; + +static unsigned read_class[] = { +#include +~0U +}; + +static unsigned write_class[] = { +#include +~0U +}; + +static unsigned chattr_class[] = { +#include +~0U +}; + +static unsigned signal_class[] = { +#include +~0U +}; + +int audit_classify_arch(int arch) +{ + if (audit_is_compat(arch)) + return 1; + else + return 0; +} + +int audit_classify_syscall(int abi, unsigned syscall) +{ + if (audit_is_compat(abi)) + return audit_classify_compat_syscall(abi, syscall); + + switch (syscall) { +#ifdef __NR_open + case __NR_open: + return AUDITSC_OPEN; +#endif +#ifdef __NR_openat + case __NR_openat: + return AUDITSC_OPENAT; +#endif +#ifdef __NR_socketcall + case __NR_socketcall: + return AUDITSC_SOCKETCALL; +#endif +#ifdef __NR_execveat + case __NR_execveat: +#endif + case __NR_execve: + return AUDITSC_EXECVE; +#ifdef __NR_openat2 + case __NR_openat2: + return AUDITSC_OPENAT2; +#endif + default: + return AUDITSC_NATIVE; + } +} + +static int __init audit_classes_init(void) +{ +#ifdef CONFIG_AUDIT_COMPAT_GENERIC + audit_register_class(AUDIT_CLASS_WRITE_32, compat_write_class); + audit_register_class(AUDIT_CLASS_READ_32, compat_read_class); + audit_register_class(AUDIT_CLASS_DIR_WRITE_32, compat_dir_class); + audit_register_class(AUDIT_CLASS_CHATTR_32, compat_chattr_class); + audit_register_class(AUDIT_CLASS_SIGNAL_32, compat_signal_class); +#endif + audit_register_class(AUDIT_CLASS_WRITE, write_class); + audit_register_class(AUDIT_CLASS_READ, read_class); + audit_register_class(AUDIT_CLASS_DIR_WRITE, dir_class); + audit_register_class(AUDIT_CLASS_CHATTR, chattr_class); + audit_register_class(AUDIT_CLASS_SIGNAL, signal_class); + return 0; +} + +__initcall(audit_classes_init); -- cgit v1.3.1
