30bae2ca47 fs/cromfs: Fix faulty DEBUGASSERT() check 
The logic being tested is wrong, obviously when accessing file the
driver private data has to be valid (open() has been called).

moving mmap beforee truncate could make three struct more compatible

b256b2055f Add support to hard links to CROMFS 
This will resolve numerous problems with the way that hard links, in particular "." and ".." are handled.  Instead of trying to fudge the stat flags, the correct implementation is to follow the hard link to the final link target node.  That is what must determine the attributes of the directory entry.

dd97fb991b This commit moves shared builtin information out of binfmt/libbuiltin and into libs/libc/builtin where it can be shared. This should permit builtin application in the PROTECTED build where binfmt/libbuiltin is not available in user space. 
Squashed commit of the following:

    Correct some additional compile-related issues.

    Move  include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h.  Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.

    Move binfmt/libbuiltin to libs/libc/builtin.  There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.

67e0603b5a fs/cromfs: Block length only needs to be uint16_t, not uint32_t. Add pading to node structure to assue that alignment is the same on all platforms. tools/gencromfs.c: Fix the target offset of the '.' hard link. 2018-03-24 14:44:38 -06:00

8b4b61f140 fs/cromfs: Fix a error in reading partial compressed blocks. The LZF decompressor does not support that operation. Instead we have to decompress full block into a temporary buffer and copy out the parts that we need. To compensate for the performance hit, a caching mechanism was added so that we do not have to read the same block repeatedly. Unrelated: Also updates some README files. 2018-03-24 11:30:35 -06:00

Use uint32_t instead of size_t for offsets. Use uint16_t instead of mode_t. 2018-03-20 12:37:01 -06:00

0478b5bce4 Addes CROMFS prototype. CROMFS is a commpressed, in-memory read-only file system based on LZF. 
Squashed commit of the following:

    fs/cromfs:  Now depends on EXPERIMENTAL because it is not yet verified.
    fs/cromfs:  This commit brings the CROMFS file system to code complete.  Still completely untested.  Next steps:  Need a tool to generate CROMFS file system images and a test case under apps/
    fs/cromfs:  Add logic to traverse the in-memory file system nodes.
    fs/cromfs:  Add initial support for an in-memory, compressed, read-only file system.
