[OE-core] [PATCH 2/2] dosfstools: Remove initial directory contents feature

Darren Hart dvhart at linux.intel.com
Fri Dec 16 06:14:20 UTC 2011


By using mtools, we don't need to continue to maintain and workaround
the issues generated by the -d feature included in the OE version of
mkdosfstools. This reduces the number of out-of-tree patches we have to
carry by 3 and eliminates a rather buggy chunk of code.

Drop the initial patch adding -d as well as those applied to improve it
and those applied to work around its deficiencies.

-UpstreamStatus: Inappropriate
-
-This patch fixes populated dosfs image creation with directory 
-structures. Earlier it was causing segfault; and only image 
-population with no subdirectories was working.
-
-Issues fixed:
-1. (dir->count == dir->entries) check was only needed for root 
-   directory entries. And this check is wrong for non-root 
-   directories.
-2. For each dir entry 2 dir->table entries were needed, one for 
-   the file/dir and 2nd for long file name support. Earlier long
-   name support was added for filenames but the 2nd entry 
-   allocation, initialization & counting was missed.
-3. The memory clearing was missed at the code path after dir->table 
-   memroy allocation.
-4. Add entries for . & .. directories in all non-root directories.
-5. The . directory points to the correct entry in fat now.
-6. All directoriy entries' size was not zero as required for dosfsck,
-   Now all directory entries' size is zero.
-
-Enhancements:
-1. Added support for long names for directory names. This is same
-   as the existing long name support for filenames.
-2. Added error messages for previously silent memory allocation and 
-   other errors.
-3. -d options does not work correctly with fat32, so now throwing 
-   an error for that.
-4. Use predefined structures from kernel's msdos_fs.h file, rather 
-   than defining again here. And accordingly change the names & use
-   of structure variables.
-
-Outstanding Issues:
-1. The .. directory entry do not point to the parent of current
-   directory. This issue can be fixed by running dosfsck -a after
-   image creation.
-2. For files the filesize is correct, but the clusters size is more 
-   than it needs to be, this also can be fixed by running dosfsck -a
-   after image creation.

-FAT32 appears to be broken when used with the -d option to populate the msdos
-image. This disables the FAT32 autoselection code which means we don't get
-broken images with the -d option. It can still be enabled on the commandline
-at the users own risk. This changes us back to the 2.10 version's behaviour
-which was known to work well even with large images.
