Title:
Access right (execute) is not correct deduced by Ubuntu-client from
NFSv3 Access Reply.
Status in apport package in Ubuntu:
Expired
Bug description:
release of Ubuntu:
Ubuntu 12.04.2 LTS
version of the package:
nfs-common 1:1.2.5-3ubuntu3.1
Description of problem:
NFSv3 mounted export (mount -t nfs -o nfsvers=3,acl)
NFS-Client does an Access Call to determinate the Access rights for users
actual UID/GID for a file.
The received Access right (EXECUTE) isn't correct deduced by Ubuntu-client
from NFSv3 Protocols Access Reply.
How reproducible:
NFS-Server on IBM GPFS filesystem with activated ACL-support or similiar.
Users UID is autorized in ACE with read,write and execute rights, but
mapped posix permissions (OWNER@, GROUP@ EVERYONE@) for this file has no
execute rights.
114364@client:~$ id
uid=114364(******) gid=1029(******) groups=1029(******)
mapped standard posix permissions:
114364@client:~$ ll -n
-rw------- 1 30006 201 17 Mar 20 19:23 execute-test.sh
ACL output -> ACE for user (UID:114364) has execute rights:
----------------------------------------------------------------------------
#NFSv4 ACL
#owner:30006
#group:201
user:114364:rwxc:allow:Inherited
(X)READ/LIST (X)WRITE/CREATE (-)MKDIR (X)SYNCHRONIZE (X)READ_ACL
(X)READ_ATTR (X)READ_NAMED
(X)DELETE (X)DELETE_CHILD (X)CHOWN (X)EXEC/SEARCH (X)WRITE_ACL
(X)WRITE_ATTR (X)WRITE_NAMED
special:owner@:rw--:allow:Inherited

(X)READ_ATTR (X)READ_NAMED
(X)DELETE (-)DELETE_CHILD (-)CHOWN (-)EXEC/SEARCH (-)WRITE_ACL
(X)WRITE_ATTR (X)WRITE_NAMED
----------------------------------------------------------------------------
Actual results:
114364@client:~$ ./execute-test.sh
bash: /mnt/id_sd_test_ane/x-test/execute-test.sh: Permission denied
Expected results:
114364@client:~$ ./execute-test.sh
-> execution of file successful
additional info:
In general, it is not sufficient for the client to attempt to deduce access
permissions by inspecting the uid, gid, and mode fields in the file attributes
client misinterprets the execute rights through replied mode (600) in
obj_attributes.
