Hi, robert I am reading the ACL implementation based FreeBSD5.0 release. I have some problems, please help. 1. the 'extattrctl initattr -p / 388 posix1e.acl_access' command: why the size is 388. the 'ufs_extattr_header' size is 12 and the 'acl' is 324, so the sum is 336. 2. what is the relationship of ACL_GROUP_OBJ and ACL_MASK? If I do not set the ACL EA, we can not get the information of 'ACL_MASK'. ACL_MASK represents what? 3. "As part of the ACL is stored in the inode, and the rest in an EA, assemble both into a final ACL product. Right now this is not done very efficiently.", Do you any viewpoint about that? How we can improve the efficiency? 4. about ACL based on UFS2, do the ACLs of an inode store di_extb? Could you introduce the ACLs' management on UFS2? Thank you very much!
