* termios: Replace rtems_termios_isig_status_codeSebastian Huber2020-05-071-19/+28
| | | | | | | | | | Merge the rtems_termios_isig_status_code and rtems_termios_iproc_status_code enums into a single rtems_termios_iproc_status_code which is now a part of the API. Simplify rtems_termios_posix_isig_handler() to avoid unreachable code. Close #3800.

| | | | | | | | | | | | This define is * not documented, * not used in the RTEMS code base, and * longer than sizeof(rtems_name). Close #3971.

* libmisc/shell: Fix the handling of joel scripts in telnetChris Johns2020-04-151-1/+6
| | | | | | | | | | | | - Fix the passing of std[in/out] to child threads - Fix deleting of managed memory in the key destructor - Only set the key in the main loop thread - Only allocate a shell env outside of the main loop - Fix memory leak if the task start fails - Remove error level from shell env, it cannot be returned this way. Add exit_code but the API is broken so it cannot be returned. Closes #3859

* config: Fix _ISR_Stack_area_endSebastian Huber2020-04-081-6/+9
| | | | | | | | | | | | | | In the previous implementation, the _ISR_Stack_area_begin and _ISR_Stack_area_end symbols were in different sections. If they do not have the same alignment, then the following linker directive could separate them: *(SORT_BY_ALIGNMENT (SORT_BY_NAME (.rtemsstack*))) Do not use different sections and instead define _ISR_Stack_area_end directly. Update #3799.

| | | | | | | | | | The _ISR_Stack_area_begin and _ISR_Stack_area_end symbols are in different sections. They must have the same alignment, otherwise the following linker directive could separate them: *(SORT_BY_ALIGNMENT (SORT_BY_NAME (.rtemsstack*))) Update #3799.

* ftpd: Remove superfluous definesSebastian Huber2020-03-311-9/+0
| | | | | | These defines are not used and easily conflict with application code. They are also defined by the standard header file <arpa/ftp.h> if someone needs them.

* score: Fix size of TLS_Thread_control_blockSebastian Huber2020-03-231-1/+3
| | | | | On most architectures, the size of the thread-local storage TCB must be 8 bytes. Fix the definition for 64-bit targets.

| | | | | | | Check for configuration errors earlier. Allow fatal dumps without the other extensions. Add some warnings. Update #3904.

| | | | | | | | | Add rtems_record_dump_base64() and rtems_record_dump_base64_zlib(). Add CONFIGURE_RECORD_FATAL_DUMP_BASE64 and CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB configuration options. Update #3904.

* libio: Robust file descriptor reference countingSebastian Huber2020-03-132-24/+2
| | | | | | | | | | | | There was a race conditon in the reference counting of file descriptors during a close() operation. After the call to the close handler, the rtems_libio_free() function cleared the flags to zero. However, at this point in time there may still exist some holders of the file descriptor. With RTEMS_DEBUG enabled this could lead to failed assertions in rtems_libio_iop_drop(). Change the code to use only atomic read-modify-write operations on the rtems_libio_iop::flags.
* imfs: Replace devfs with an IMFS specializationSebastian Huber2020-03-095-320/+49
| | | | | | | | | | | | | | | | Add a simplified path evaluation function IMFS_eval_path_devfs() for a device only IMFS configuration. The code size can be further reduced by the application if it disables the support for legacy IO drivers via: #define CONFIGURE_IMFS_DISABLE_MKNOD #define CONFIGURE_IMFS_DISABLE_MKNOD_DEVICE Obsolete CONFIGURE_MAXIMUM_DEVICES. Remove BSP_MAXIMUM_DEVICES. Update #3894. Update #3898.
* imfs: Constify imfs_memfile_bytes_per_blockSebastian Huber2020-03-092-3/+2
| | | | | | | | The CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK value is validated by <rtems/confdefs/libio.h>. Changing this value during runtime could lead to memory corruption. Update #3894.

* imfs: Remove IMFS_NODE_FLAG_NAME_ALLOCATEDSebastian Huber2020-03-041-3/+0
| | | | | | | | Remove IMFS_NODE_FLAG_NAME_ALLOCATED and instead replace the node control in rename operations. This avoids a special case in the general node destruction which pulled in free(). Update #3894.
* rtems: rtems_scheduler_get_processor_maximum()Sebastian Huber2020-03-041-2/+3
| | | | | | | | | | | | In uniprocessor configurations, use compile-time constants for rtems_scheduler_get_processor_maximum() and rtems_scheduler_get_processor(). This helps compilers and static analyzers to deduce that some loop bodies are only executed once and some conditional statements have a fixed outcome (may improve code generation and reduce false positives). In SMP configurations, directly provide the internal implementation for performance reasons.
* config: Remove <rtems/btimer.h> includeSebastian Huber2020-03-041-4/+0
| | | | | | | The use of CONFIGURE_APPLICATION_NEEDS_TIMER_DRIVER does not define anything, so remove the <rtems/btimer.h> include. Update #3875.

* score: Fix context switch extensions (SMP)Sebastian Huber2020-02-282-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In uniprocessor and SMP configurations, the context switch extensions were called during _Thread_Do_dispatch(): void _Thread_Do_dispatch( Per_CPU_Control *cpu_self, ISR_Level level ) { Thread_Control *executing; executing = cpu_self->executing; ... do { Thread_Control *heir; heir = _Thread_Get_heir_and_make_it_executing( cpu_self ); ... _User_extensions_Thread_switch( executing, heir ); ... _Context_Switch( &executing->Registers, &heir->Registers ); ... } while ( cpu_self->dispatch_necessary ); ... } In uniprocessor configurations, this is fine and the context switch extensions are called for all thread switches except the very first thread switch to the initialization thread. However, in SMP configurations, the context switch may be invalidated and updated in the low-level _Context_Switch() routine. See: https://docs.rtems.org/branches/master/c-user/symmetric_multiprocessing_services.html#thread-dispatch-details In case such an update happens, a thread will execute on the processor which was not seen in the previous call of the context switch extensions. This can confuse for example event record consumers which use events generated by a context switch extension. Fixing this is not straight forward. The context switch extensions call must move after the low-level context switch. The problem here is that we may end up in _Thread_Handler(). Adding the context switch extensions call to _Thread_Handler() covers now also the thread switch to the initialization thread. We also have to save the last executing thread (ancestor) of the processor. Registers or the stack cannot be used for this purpose. We have to add it to the per-processor information. Existing extensions may be affected, since now context switch extensions use the stack of the heir thread. The stack checker is affected by this. Calling the thread switch extensions in the low-level context switch is difficult since at this point an intermediate stack is used which is only large enough to enable servicing of interrupts. Update #3885.
