b7f958a02e binfmt/, binfmt/libelf: binfmt/elf: Call umm_initialize as soon as possible otherwise elf_loadctors/elf_loaddtors will fail to allocate memory. 2019-01-26 11:36:38 -06:00

0edcd6b85e binfmt/libelf, libs/libc/modlib: Optimize elf load speed: (1) Don't zero out memory, (2) Reduce the initial buffer size to 32 bytes. 2019-01-26 11:34:40 -06:00

264a7164bc binfmt/: If there is an address environment (CONFIG_ARCH_ADDRENV), binfmt/elf doesn't need to free ctor/dtor alloc since freeing the address environment releases the heap automatically. 2019-01-26 11:29:08 -06:00

38ffb98f1b Kconfig files, binfmt/libelf, libs/libc/machin, libs/libxx: Correct libcxx exception handling by introducing the generic config(CXX_EXCEPTION and CXX_LIBSUPCXX) 2019-01-26 11:23:31 -06:00

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.

3521aaf944 Squashed commit of the following: 
binfmt/, configs/, grahics/, libc/, mm/, net/, sched/:  OS references to the errno variable should always use the set_errno(), get_errno() macros
    arch/arm/src/stm32 and stm32f7:  Architecture-specific code is not permitted to modify the errno variable.  drivers/ and libc/:  OS references to the errno variable should always use the set_errno(), get_errno() macros

181875f3ba fs/vfs: Add new internal OS interface nx_read(). nx_read() is functionally equivalent to read() except that it does not modify the errno variable and it is not a cancellation point. Changed all references to read() in the OS to nx_read(). 2017-10-11 12:13:41 -06:00

241a7e17bd addrenv interface changes: up_addrenv_create() may need to create .text and .bss/.data separately because of differing access privileges (read/execute vs read/write).
