* Update company nameSebastian Huber2023-05-201-1/+1
| | | | | The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
* libcsupport: Added futimens() and utimensat()Ryan Long2021-05-281-8/+86
| | | | | | | | | | Created futimens.c and utimensat.c to add support for the POSIX methods futimens() and utimensat(). utime() and utimes() are considered obsolote by POSIX, but RTEMS will continue to support them. Closes #4396
* libio: Robust file descriptor reference countingSebastian Huber2020-03-131-23/+1
| | | | | | | | | | | | 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.

* libio: Add POSIX user environment pointer to TCBSebastian Huber2020-02-251-4/+0
| | | | | | | | | | The IO library used a POSIX key to store an optional POSIX user environment pointer. This pulled in the POSIX keys support in every application configuration. Add a user environment pointer to the thread control block (TCB) instead. Applications which do not need the POSIX user environment will just get an overhead of one pointer per thread. Close #3882.

* Remove make preinstallChris Johns2018-01-251-0/+1049
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

| | | | | | | * libc/libio.c: Initialize more fields to NULL/0 during initialiation. * include/rtems/libio_.h: Fix freenode macro so it works for sockets which do not have the full set of filesystem operations and are initialized via something other than open().

| | | | | | | | * include/rtems/libio_.h: Added ifdef to ensure that LOGIN_NAME_MAX is defined on GNU/Linux (RedHat 6.2 distribution). * libc/unixlibc.c: Added stubs for rtems_io_register_name() and rtems_io_lookup_name() so UNIX port would compile the IO manager sptest that registers /dev/null.

| | | | | * include/rtems/libio_.h: Added login name, uid, gid, euid, and egid so they can be part of the private environment.

| | | | | | | | | | | | | | | | | * include/rtems/libio_.h, libc/chroot.c, libc/privateenv.c: Private environment and chroot() enhancements and fixes. Comments: + privateenv has been modified to let at chroot() to be more POSIX like Sergei Organov recommended. + A task owner lets that rtems_set_private_env() will be called twice or more times. + chroot() can be called without a previous rtems_set_private_env(); (transpanrently) + The second call of rtems_set_private_env() makes a internal chroot("/") into global imfs_root. + chroot() runs like chdir() without a previous chdir("/") with the global root. + The current directory can be in a wrong place like Linux and many other Unices.

This enable giving unique copies of these to individual threads or collection of threads.

Eventually the internal representation should be eliminated in the interest of simplicity and code reduction. This problem was reported by Jake Janovetz <janovetz@tempest.ece.uiuc.edu>.

* More general fix based on bug report and patch from Ian Lance TaylorJoel Sherrill1999-01-201-1/+15
| | | | | | | | | | <ian@airs.com> to fix this problem: There is a small bug in __rtems_close in c/src/lib/libc/libio.c. It does not check whether the file descriptor it is passed is open. This can cause it to make a null dereference if it is passed a file descriptor which is in the valid range but which was not opened, or which was already closed.

* Added base version of file system infrastructure. This includes a majorJoel Sherrill1998-11-231-0/+248
overhaul of the RTEMS system call interface. This base file system is the "In-Memory File System" aka IMFS. The design and implementation was done by the following people: + Joel Sherrill (joel@OARcorp.com) + Jennifer Averett (jennifer@OARcorp.com) + Steve "Mr Mount" Salitasc (salitasc@OARcorp.com) + Kerwin Wade (wade@OARcorp.com) PROBLEMS ======== + It is VERY likely that merging this will break the UNIX port. This can/will be fixed. + There is likely some reentrancy/mutual exclusion needed. + Eventually, there should be a "mini-IMFS" description table to eliminate links, symlinks, etc to save memory. All you need to have "classic RTEMS" functionality is technically directories and device IO. All the rest could be left out to save memory.
