Hi, i think i have found a bug in the unix ACL permissions.
I tested this problem in the Ubuntu 9.10 and in SLES 10 and 11, all of them with setfacl 2.2.47.
Well, I have done the following test:
1) Create a folder and set some named user, and set the same ACL entry for the Default ACL, like the following example:
Code:
mkdir dir1
setfacl -m u:rodrigo:rwx dir1/
setfacl -d -m u:rodrigo:rwx dir1/
getfacl dir1/
# file: dir1/
# owner: root
# group: root
user::rwx
user:rodrigo:rwx
group::r-x
mask::rwx
other::r-x
default:user::rwx
default:user:rodrigo:rwx
default:group::r-x
default:mask::rwx
default:other::r-x
At this moment I'm getting the following result when I type ls -l:
Code:
drwxrwxr-x+ 3 root root 4096 2010-04-18 10:35 dir1
Note that the permissions for the owner group is different than the ones shows by the getfacl command!
2) Now I create a file in this directory, that should inherit the Default ACL from dir1/
Code:
cd dir1/
touch file1
getfacl dir1/
# file: file1
# owner: rodrigo
# group: rodrigo
user::rw-
user:rodrigo:rwx #effective:rw-
group::r-x #effective:r--
mask::rw-
other::r--
Note that some permissions are different from the ones in the Default ACL in the dir1/
My question is: why the file1's permissions are diferrent from the dir1's default ACL entries? Is this a bug?
Thanks for reading!
