[RFC 0/2] ima: Fix detection of read/write violations on stacked filesystems

Posted by Stefan Berger 1 year, 10 months ago

This series fixes the detection of read/write violations on stacked
filesystems. To be able to access the relevant dentries necessary to
detect files opened for writing on a stacked filesystem a new d_real_type
D_REAL_FILEDATA is introduced that allows callers to access all relevant
files involved in a stacked filesystem.
