[gpfsug-discuss] Enforce ACLs

[Fosburgh,Jonathan]

I'm not 100% sure this is that it is, but it is most likely your ACL config. If you have to use the nfsv4 ACLs, check in mmlsconfig to make sure you are only using nfsv4 ACLs. I think the options are posix, nfsv4, and both. I would guess you are set to both.

Subject: [EXT] [gpfsug-discuss] Enforce ACLs

Hello,

we are using GPFS 4.2.3 and at the moment we are looking into acls and
inheritance.

I have the following acls on a directory:
#NFSv4 ACL
#owner:root
#group:root
special:owner@:rwxc:allow:FileInherit:DirInherit
 (X)READ/LIST (X)WRITE/CREATE (X)APPEND/MKDIR (X)SYNCHRONIZE
(X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (X)DELETE_CHILD (X)CHOWN        (X)EXEC/SEARCH
(X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

special:group@:r-x-:allow:FileInherit:DirInherit
 (X)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (X)SYNCHRONIZE
(X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-
)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

special:everyone@:----:allow:FileInherit:DirInherit
 (-)READ/LIST (-)WRITE/CREATE (-)APPEND/MKDIR (-)SYNCHRONIZE (-
)READ_ACL  (-)READ_ATTR  (-)READ_NAMED
 (-)DELETE    (-)DELETE_CHILD (-)CHOWN        (-)EXEC/SEARCH (-
)WRITE_ACL (-)WRITE_ATTR (-)WRITE_NAMED

user:userABC:rwx-:allow:FileInherit:DirInherit
 (X)READ/LIST (X)WRITE/CREATE (X)APPEND/MKDIR (X)SYNCHRONIZE
(X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (X)DELETE    (X)DELETE_CHILD (-)CHOWN        (X)EXEC/SEARCH (-
)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED



Then the user creates a new folder in this directory and it does not
get the same acl but normal unix permissions.
Is there any way to enforce the new permissions from the parent?

Kind regards
 Philipp
