Hi,
This patchset is base on [1] and [2], adding implementation of ACLs for ubifs.
Implement ACLs features based on POSIX to solve some difficulties that require fine-grained access control. At the same time, it is also to facilitate cross-file system migration.
In order to simplify the implementation, only v2 version POSIX ACLs are implemented, eliminating the need for in-memory and on-flash format conversion. And no need to implement security xattr handler in ubifs.
Some testcases have been tested and passed: * generic testcases (modified version) for acl group in xfstest[3], they are generic/026/053/077/099/105/237/307/318/319/375/389/444/449/529/697. * tacl_xattr.sh (modified version) in LTP[4].
