Bug with unmounting a non-existing mountpoint. The function returns ENODEV
but should be returning EINVAL.
- Unmount2 forcing the unmount needs to break the handles so they return EBADF.
-
- Bug with reading -1 bytes of a file without an error (test is in test_yaffs_read_EINVAL).
- It should return EINVAL. This is because it was reading an empty file.
- When text is added to the file a read of -1 bytes tries to read 4 gig of data
Bug when writing a file. The writing to the file causes the file size to exceed the size of yaffs file system memory.
Output of test:
- test_yaffs_write_EFBIG
+ test_yaffs_write_big_file

wrote a large amount of text to a file.(which is a bad thing)
