542574acd6 libs/libc/modlib/modlib_init.c: initialize file descriptor with -1
Use -1 instead of 0 to represent an invalid descriptor
so that modlib_uninitialize doesn't try to close the descriptor 0.

33aaefa2d1 modlib: Replace Gregory Nutt's copyright notice with Apache 2.0
While I'm here adding a new file. (modlib_loadshdrs.c)

The licence text was copied from:

7cfcea2938 Move modlib_loadshdrs to a separate file
To avoid pulling otherwise unused modlib_findsection when linking.

81f1133174 ELF64 support (#220)
* include: Introduce elf64.h and elf.h

    Added elf64.h for 64bit ELF support and moved common definitions
    from elf32.h to elf.h. Also introduced Elf_xxx to be used in
    common libraries such as binfmt.

  * binfmt, include, modlib, module: Add support for ELF64

    Elf_xxx must be used instead of Elf32_xxx to support ELF64.
    To use ELF64, CONFIG_ELF_64BIT must be enabled.

  * binfmt, modlib: Add support for relocate address

  * arch: risc-v: Add include/elf.h

  * libs: machine: Add risc-v related files.

    NOTE: Currently only supports ELF64

  * boards: maix-bit: Add elf and posix_spawn configurations

  * boards: maix-bit: Add support for module configuration

5c80b94820 Replace #include <semaphore.h> to #include <nuttx/semaphore.h>
Since the kernel side should call nxsem_xxx instead and remove the unused inclusion

6a3c2aded6 Fix wait loop and void cast (#24)
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

095e28d45e binfmt/, binfmt/libelf/, include/nuttx, libs/libc/machine, libs/libc/modlib, and others: Move elf related arch function to include/nuttx/elf.h because the implementation is located in libs/libc/machine and in order to avoid the conflict with the 3rd party libraries and clean up the file inclusion: (1) Remove redundant elf32.h, (2) Remove nuttx/binfmt/elf.h in libs/libc/machine, (2) Remove nuttx/binfmt/elf.h in modlib, and (4) Rmove nuttx/module.h in modlib. 2019-01-26 11:18:45 -06:00

a7fd58c4db Squashed commit of the following:
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
