[RFC][PATCH 3/4] selinux: use file->f_cred to determine task's SID

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Security IDentifier to be associated to the newly created file
descriptor is computed from the credentials set in the 'f_cred' field of
the same structure instead of those relative to the 'current' process.
