* 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.

* 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.

* 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.

| | | | | | | | 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.

| | | | | | | | | | | | | Searching for duplicate names scales O(n^2) with the number of names added to a fdt, which can cause a noticable slowdown with larger device trees and very slow CPU cores. Add FDT_CREATE_FLAG_NO_NAME_DEDUP that allow the caller to trade fdt size for speed in the creation process.

* libfdt: Introduce fdt_create_with_flags()Nicholas Piggin2020-03-021-1/+37
| | | | | | | | | | | | | | | | | | | | | | | There is a need to be able to specify some options when building an FDT with the SW interface. This can be accomplished with minimal changes by storing intermediate data in the fdt header itself, in fields that are not otherwise needed during the creation process and can be set by fdt_finish(). The fdt.magic field is already used exactly this way, as a state to check with callers that the FDT has been created but not yet finished. fdt.version and fdt.last_comp_version are used to make room for more intermediate state. These are adjacent and unused during the building process. last_comp_version is not yet used for intermediate state, but it is zeroed and treated as used, so as to allow future growth easily. A new interface, fdt_create_with_flags() is added, which takes 32-bit flag value to control creation.

* libfdt: Make fdt_get_max_phandle() an inlineDavid Gibson2020-03-021-1/+11
| | | | | | | | | | It's now a trivial wrapper around fdt_find_max_phandle() so we might as well inline it. We also remove it from the versioning linker script. Theoretically, that's a breaking ABI change except that we haven't yet released a version with it exposed in the shared object, so we can get away with it.

* libfdt: Add phandle generation helperThierry Reding2020-03-021-0/+19
| | | | | | | | | | | | | | | | | The new fdt_generate_phandle() function can be used to generate a new, unused phandle given a specific device tree blob. The implementation is somewhat naive in that it simply walks the entire device tree to find the highest phandle value and then returns a phandle value one higher than that. A more clever implementation might try to find holes in the current set of phandle values and fill them. But this implementation is relatively simple and works reliably. Also add a test that validates that phandles generated by this new API are indeed unique.

* libfdt: Add new maximum phandle lookup functionThierry Reding2020-03-022-0/+17
| | | | | | | | | | | | | | | | | | | | | | The fdt_get_max_phandle() function has some shortcomings. On one hand it returns just a uint32_t which means to check for the "negative" error code a caller has to explicitly check against the error code (uint32_t)-1. In addition, the -1 is the only error code that can be returned, so a caller cannot tell the difference between the various failures. Fix this by adding a new fdt_find_max_phandle() function that returns an error code on failure and 0 on success, just like other APIs, and stores the maximum phandle value in an output argument on success. This also refactors fdt_get_max_phandle() to use the new function. Add a note pointing out that the new fdt_find_max_phandle() function should be preferred over fdt_get_max_phandle().
