06:15 Changeset in rtems [3ad5f86]5 by Sebastian Huber <sebastian.huber@…>
rtems: Fix no protocol mutex release The Classic binary semaphores without a locking protocol (RTEMS_BINARY_SEMAPHORE) could be released by everyone, e.g. in contrast to the POSIX mutexes (all variants) or the Classic binary semphores with priority inheritance or ceiling, there was no owner check in the release path. This behaviour was a bit unexpected and not documented. Add an owner check to the release path. Update sptests/sp42 accordingly. This change has nothing to do with the simple binary semaphores (RTEMS_SIMPLE_BINARY_SEMAPHORE) which have no owner at all. Update #2725

score: Maybe fix _Thread_Lock_acquire() The approach with the generation number was broken. The load/store of the current lock, the thread queue and the thread queue operations were not properly synchronized. Under certain conditions on a PowerPC T4240 old thread queue operations operated on a new thread queue (NULL pointer).
09:04 Changeset in rtems [f807b84]5 by Sebastian Huber <sebastian.huber@…>
score: Fix _Thread_Lock_acquire() A read-modify-write operation is necessary to read the last value written. See for example C11 standard or Power ISA 2.07, Book II: Power ISA Virtual Environment Architecture, Section 1.6.3 Memory Coherence Required [Category: Memory Coherence] and Section 1.7.3 Atomic Update.

Retune SHA2 code for improved performance on CPUs with more ILP and a preference for memory load instructions over large code footprints with embedded immediate variables. On amd64 CPUs from 2007-2008 there is not a significant change, but amd64 CPUs from 2009-2010 get roughly 10% more throughput with this code; amd64 CPUs from 2011-2012 get roughly 15% more throughput; and AMD64 CPUs from 2013-2015 get 20-25% more throughput. The Raspberry Pi 2 increases its throughput by 6-8%. Sponsored by: Tarsnap Backup Inc. Performance tested by: allanjude MFC after: 3 weeks

16:06 Changeset in rtems [7b4296e] by Allan Jude <allanjude@…>
Implement SHA-512 truncated (224 and 256 bits) This implements SHA-512/256, which generates a 256 bit hash by calculating the SHA-512 then truncating the result. A different initial value is used, making the result different from the first 256 bits of the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on 64bit platforms, so the result is a faster 256 bit hash. The main goal of this implementation is to enable support for this faster hashing algorithm in ZFS. The feature was introduced into ZFS in r289422, but is disconnected because SHA-512/256 support was missing. A further commit will enable it in ZFS. This is the follow on to r292782 Reviewed by: cem Sponsored by: ScaleEngine? Inc. Differential Revision: ​https://reviews.freebsd.org/D6061

12:43 Changeset in rtems [93306058]5 by Sebastian Huber <sebastian.huber@…>
score: _CORE_mutex_Check_dispatch_for_seize() Move the safety check performed by _CORE_mutex_Check_dispatch_for_seize() out of the performance critical path and generalize it. Blocking on a thread queue with an unexpected thread dispatch disabled level is illegal in all system states. Add the expected thread dispatch disable level (which may be 1 or 2 depending on the operation) to Thread_queue_Context and use it in _Thread_queue_Enqueue_critical().

score: Add _Thread_queue_Context_set_MP_callout() Add _Thread_queue_Context_set_MP_callout() to simplify _Thread_queue_Context_initialize(). This makes it possible to more easily add additional fields to Thread_queue_Context.

crypto routines: Hint minimum buffer sizes to the compiler Use the C99 'static' keyword to hint to the compiler IVs and output digest sizes. The keyword informs the compiler of the minimum valid size for a given array. Obviously not every pointer can be validated (i.e., the compiler can produce false negative but not false positive reports). No functional change. No ABI change.

score: Add Status_Control for all APIs Unify the status codes of the Classic and POSIX API to use the new enum Status_Control. This eliminates the Thread_Control::Wait::timeout_code field and the timeout parameter of _Thread_queue_Enqueue_critical() and _MPCI_Send_request_packet(). It gets rid of the status code translation tables and instead uses simple bit operations to get the status for a particular API. This enables translation of status code constants at compile time. Add _Thread_Wait_get_status() to avoid direct access of thread internal data structures.
