* clock:_TOD_To_seconds(): Fix year 2514 overflowFrank Kühndel2021-04-211-0/+16
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes issue #4338 by changing _TOD_Validate() to only accept years till 2105. This requires another patch to change the documentation of rtems_clock_set() and other affected API functions (indicating the end date is 2105 not 2514). I tried to support till year 2514 but it turned out that this needs changing the Timer Manager too. That in turn would mean to change _TOD_Seconds_since_epoch( void ) from 32 to 64 bit. Sebastian pointed out that a naive extension leads to trouble with 32 bit processors. He deemed a safe re-implementation too costly performance wise considering that year 2106 is far away and current binaries using RTEMS Classic API are unlikely to be in use by 2106. The constant TOD_SECONDS_AT_2100_03_01_00_00 in cpukit/rtems/src/clocktodtoseconds.c happens to be wrong by 1 hour. When setting the date 2100-Feb-28 23:59:59 and then reading the date again you will find yourself in 2100-Feb-27. Update #4338
* malloc: Hide RTEMS_Malloc_Sbrk_amountSebastian Huber2021-04-201-6/+1
| | | | | | Move RTEMS_Malloc_Sbrk_amount to the only implementation file which uses it and make it private to hide implementation-details from an API header.

* Revert "cpukit/include: Remove telnetd.h"Vijay Kumar Banerjee2021-04-131-0/+137
| | | | This reverts commit 8383572963e261ea384cddfa43cd9606e7c23cdd.
* cpukit/include: Remove telnetd.hVijay Kumar Banerjee2021-04-071-137/+0

| | | | Update #3850
* rtems: Fix rtems_semaphore_release() documentationSebastian Huber2021-04-071-1/+1
| | | | | The directive returns RTEMS_UNSATISFIED if the semaphore's count already had the maximum value of UINT32_MAX.
* score: Replace Objects_Name_or_id_lookup_errorsSebastian Huber2021-04-074-49/+23
| | | | | Replace Objects_Name_or_id_lookup_errors with new Status_Control codes. Get rid of the _Status_Object_name_errors_to_status lookup table.
* score: Fix internal error status numberSebastian Huber2021-04-071-2/+2
| | | | | | The value of STATUS_CLASSIC_INTERNAL_ERROR must be equal to RTEMS_INTERNAL_ERROR. Add static assertions to ensure that the status codes match.
* score: Fix task stack initializationSebastian Huber2021-03-272-11/+24
| | | | | | | | | Do not adjust the stack area begin address since this may confuse the stack allocator and result in failed stack frees. Account for the alignment overhead in the stack space size estimate. Check that the stack size is in the expected interval.
* libblock: Add rtems_bdbuf_peek()Christian Mauderer2021-03-262-2/+45
| | | | | | | | Adds a peek function that allows (for example) a file system to suggest the next blocks that should be used for read ahead. This can increase the read speed of fragmented files. Update #3689
* rtems: Allow initially locked MrsP semaphoresSebastian Huber2021-03-162-9/+22
| | | | | | Rejecting initially locked MrsP semaphores was due to a limitiation of the early limitiation of the MrsP protocol. This limitation no longer exists.
* rtems: Require RTEMS_PRIORITY for MrsP semaphoresSebastian Huber2021-03-161-1/+2
| | | | | | | | | MrsP semaphores are a generalization of the priority ceiling semaphores for SMP configurations. Priority ceiling semaphores are required to use the priority task wait queue discipline. Require this discipline also for MrsP semaphores. Close #4347.
* score: Add Thread_Configuration::cpu_time_budgetSebastian Huber2021-03-162-13/+18
| | | | | Move the CPU time budget to the thread configuration. This simplifies _Thread_Initialize().

* cpukit: Explicitly enforce alignment requirementsKinsey Moore2021-03-051-20/+32
| | | | | | | | | | | According to commentary on GCC bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99143, the alignment behavior of linker sections on which RTEMS has relied was never guaranteed to be consistent across platforms and any alignment requirements for linker sections needs to be enforced explicitly. This adds those explicit alignment requirements. Closes #4255.
* score: Ensure stack alignment requirementSebastian Huber2021-03-053-13/+30
| | | | | | | | Make sure that a user-provided stack size is the minimum size allocated for the stack. Make sure we meet the stack alignment requirement also for CPU ports with CPU_STACK_ALIGNMENT > CPU_HEAP_ALIGNMENT.
* CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZESebastian Huber2021-03-051-0/+5
| | | | | Ensure that CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZE meets the task storage alignment requirement.
* rtems: Fix RTEMS_TASK_STORAGE_ALIGNMENTSebastian Huber2021-03-041-1/+1
| | | | | Make sure we meet the stack alignment requirement for user-provided thread storage areas.
* score: Fix _Stack_Extend_size()Sebastian Huber2021-03-011-7/+21
| | | | | Check for an integer overflow. Add a validation test for task create errors.
* score: Fix thread initializationSebastian Huber2021-02-262-10/+19
| | | | | | | | Close the thread object if a thread create extension fails. Also call the delete extension to avoid resource leaks in early extensions if a late extension fails. Close #4270.

| | | | Update #4269.
* config: Adjust stack allocator initializationSebastian Huber2021-02-242-2/+2
| | | | | | | Use the right system initialization step for the stack allocator initialization. Do the stack allocator initialization before the workspace initialization so that _Memory_Allocate() can be used to get memory for the allocator.

* rtems: Move rtems_task_priority definitionSebastian Huber2021-02-243-4/+11
| | | | | | This type is not only used by Task Manager directives. This is a preparation to move the rtems_scheduler_*() directives from <rtems/rtems/tasks.h> to a new <rtems/rtems/scheduler.h>.
* score: Remove _CORE_barrier_Do_flush()Sebastian Huber2021-02-241-17/+6
| | | | Call _Thread_queue_Flush_critical() directly.
* score: Simplify core barrierSebastian Huber2021-02-242-80/+32
| | | | | | Use the number of threads which must arrive at the barrier to trip the automatic release also to indicate if the barrier is a manual release barrier.
* score: Remove _Objects_Open()Sebastian Huber2021-02-242-41/+23
| | | | | Use the type safe _Objects_Open_u32() instead. Return the object identifier to enforce a common usage pattern.

| | | | Update #4244.

| | | | | | Ensure that no invalid modes are set during ASR processing. Update #4244.
* rtems: Remove _Modes_Set_interrupt_level()Sebastian Huber2021-02-201-14/+0
| | | | | | This call just obfuscated the call to _ISR_Set_level(). Update #4244.
* rtems: Simplify signal handlingSebastian Huber2021-02-203-102/+0
| | | | | | | Remove superfluous ASR_Information::signals_posted. Move code out of trivial inline functions. Update #4244.

| | | | Update #4244.
* score: Change thread action lockingSebastian Huber2021-02-201-8/+11
| | | | | | | | Require that the corresponding lock is acquired before the action handler returns. This helps to avoid recursion in the signal processing. Update #4244.
