[RFC][PATCH 0/4] eCryptfs credentials patches

[Roberto Sassu]

This patch set modifies the credentials presented by eCryptfs to open
inodes in the lower filesystem. These credentials are initially obtained
through the function prepare_kernel_cred() and may be overridden in order
to identify or restrict actions performed by a specific eCryptfs
filesystem.

More details about how to manage the eCryptfs credentials and how to
measure eCryptfs files with IMA can be found in the file:

'Documentation/filesystems/ecryptfs-security.txt'
