In a few places, we where using a fixed buffer of sizeof(Dir)+100 size for stat. This is not correct and fails if the name returned in stat is long. This results in being unable to seek to the end of file with a long filename. The kernel should do the same thing as dirfstat() from libc; handling the conversion and buffer allocation and returning a freeable Dir* pointer. For this, a new dirchanstat() function was added. The fstat syscall was not rewriting the name to the last path element; fix it. In addition, gracefully handle the mountfix case, reallocating the buffer to accomidate the required stat length plus size of the new name so dirsetname() does not fail. |
