Current BUGS
- NAME SIZE
- Bug with opening a file with a name of 1,000,000 char long with no errors.
- The open function should be returning ENAMETOOLONG.
-
- Bug with unlinking a file with 1,000,000 get the error ENOENT but should
- be geting ENAMETOOLONG.
-
- Bug with mounting a too long non-existant mount point is returning
- ENODEV. yaffs_mount should be returning ENAMETOOLONG.
- When the name is passed into the yaffs_mount function the length of the
- mount point decreases from around 10000000 to 200. This needs to be investigated.

-
- ENOTDIR ERRORS
- Bug when trying to access a non-existing directory the error ENOENT is
- returned. It should be ENOTDIR.
-
- Bug when trying to truncate a file in a non-existing directory. The error
- returned is ENOENT it should be ENOTDIR.
+
Bug with truncating to a very large size. The yaffs_truncate function truncates the file to a massive size without any errors.
The function should return the error EINVAL.
Should cause the error EINVAL.
+ Bug when writing a file. The writing to the file causes the file size to exceed the size of yaffs file system memory.
