Subject: [PATCH] mountd: Fix is_subdirectory again
|
||||
|
||||
The problem was that is_subdirectory() would also succeed if the two
|
||||
directories were the same. This is needed for path_matches() which
|
||||
needs to see if the child is same-or-descendant.
|
||||
|
||||
So this patch rearranges path_matches() to do the "are they the same"
|
||||
test itself and only bother with is_subdirectory() if it they are not
|
||||
the same.
|
||||
|
||||
So now is_subdirectory() can be strict, and so can be usable for
|
||||
subexport(), which needs a strong 'in subdirectory - not the same' test.
