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/crypto/Kconfig | 276 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 276 insertions(+) create mode 100644 lib/crypto/Kconfig (limited to 'lib/crypto/Kconfig') diff --git a/lib/crypto/Kconfig b/lib/crypto/Kconfig new file mode 100644 index 000000000..591c1c2a7 --- /dev/null +++ b/lib/crypto/Kconfig @@ -0,0 +1,276 @@ +# SPDX-License-Identifier: GPL-2.0 + +config CRYPTO_HASH_INFO + bool + +config CRYPTO_LIB_UTILS + tristate + +config CRYPTO_LIB_AES + tristate + # Select dependencies of modes that are part of libaes. + select CRYPTO_LIB_UTILS if CRYPTO_LIB_AES_CBC_MACS + +config CRYPTO_LIB_AES_ARCH + bool + depends on CRYPTO_LIB_AES && !UML && !KMSAN + default y if ARM + default y if ARM64 + default y if PPC && (SPE || (PPC64 && VSX)) + default y if RISCV && 64BIT && TOOLCHAIN_HAS_VECTOR_CRYPTO && \ + RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS + default y if S390 + default y if SPARC64 + default y if X86 + +config CRYPTO_LIB_AESCFB + tristate + select CRYPTO_LIB_AES + select CRYPTO_LIB_UTILS + +config CRYPTO_LIB_AES_CBC_MACS + tristate + select CRYPTO_LIB_AES + help + The AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC library functions.
