Adding FILE_SHARE_READ in filter driver

NTFSD
1

Hi, all

A filter driver in its CREATE dispatch handler
adds FILE_SHARE_READ into ShareMode
for network files (for every file, regardles of
desired access, file name or whatever).

Does anyone see a caveat with it ?

A VERY unlikely scenario where two apps by same vendor use no share reading in
first to indicate something to the second? (too much philosophy here;-)
Other than that, nope.

Or some file system test application, which tests file sharing rules :slight_smile:
