David Sidrane 2953880f5c fs_cromfs: Removed DEBUGASSERT on non-exiting var node 2020-08-20 14:10:02 +01:00
Gregory Nutt 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.

Gregory Nutt b599aa0cee fs/cromfs/fs_cromfs.c: Back out an erroneous change I made during a code review. Noted by Jussi Kivilinna. 2019-12-02 08:44:50 -06:00
Gregory Nutt d2af57169b tools/nxstyle.c: Fix a rare false alarm that could occur if a variable or function name begins with the sub-string 'union' or 'struct'. misc fixes under fs/ and sched/ from application of current version of nxstyle. 2019-12-01 13:01:16 -06:00

Gregory Nutt 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.

David Sidrane b30db5dcb0 fs/cromfs/fs_cromfs.c: Fixes hardfault 2018-12-06 16:42:20 -06:00
Gregory Nutt db3b507a41 tools/gencromfs.c: Was duplicating all mode bits in source directory in CROMFS directory. Some make no sense. In particular, all write-able bits are cleard unconditionally. Executable bits are still copying because there is really no way for the tool to know if the file is executable or not. 2018-03-24 15:05:22 -06:00
Gregory Nutt 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
Gregory Nutt 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

Gregory Nutt 16d0a8c2d1 fs/cromfs: More directory traversal fixes. tools/gencromfs.c: Add ability use a callback with directory traversal. Not currently used but left in place in case it is needed in the future. 2018-03-20 16:20:31 -06:00
Gregory Nutt aeeee54921 tools/gencromfs.c and fs/cromfs: More corrections to directory traversal logic. Still some bugs. 2018-03-20 14:30:05 -06:00
Gregory Nutt 22484386ee fs/cromfs and tools/gencromfs: Various fixes for traversal relative file paths. Biggest changes is in types used: Cannot use size_t or mode_t in common structures because they have different sizes on the (64-bit) host and the (32-bit) target. Use uint32_t instead of size_t for offsets. Use uint16_t instead of mode_t. 2018-03-20 12:37:01 -06:00
Gregory Nutt 87fd4e2916 fs/cromfs: Fix read logic. tools/genromfs.c: Last node in directory needs to have zero for peer offset. Still some issues with empty directories. 2018-03-20 10:37:42 -06:00
Gregory Nutt eec44d1f01 This commit adds tools/gencromfs.c, a tool that can be used to generate CROMFS file system images.
Squashed commit of the following:

    tools/gencromfs.c:  Seems basically functional but has not has not yet been integrated with CROMFS.
    tools/gencromfs.c:  Revist previous commit.  Let's make no assumptions about the compatibility of the host system and NuttX.
    tools/gencromfs.c:  I think access mode bits are sufficiently standard that we can just copy them from the host.  This is don't mostly to pick up the executable bits and other conbinations of bits without doing a bit-for-bit decode.
    tools/gencromfs.c:  Code complete but only partially functional.
    tools/gencromfs.c:  type definitions must precede data definitions
    tools/gencromfs.c:  Adds a little more logic to gencromfs tools.  Still not complete but can traverse directories and generate directory and hard-link nodes.
    tools/gencromfs.c: Beginning of a genromfs tool that will eventually be used for generation of CROMFS file system images.

Gregory Nutt 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.
