[cs631apue] "setfacl: .: Operation not supported" when create git repo

[hao wu]

Thanks. I have done the following testing:

1. getfacl config    //ok
# file: config
# owner: hwu9
# group: student
user::rw-
group::---
mask::rwx
other::---

//strace output
getxattr("config", "system.posix_acl_access",
"\x02\x00\x00\x00\x01\x00\x06\x00\xff\xff\xff\xff\x04\x00\x00\x00\xff\xff\xff\xff\x10\x00\x07\x00\xff\xff\xff\xff
\x00\x00\x00\xff\xff\xff\xff", 132) = 36


2.setfacl -m u::w config   //fail
setfacl: config: Operation not supported

//strace output
getxattr("config", "system.posix_acl_access",
"\x02\x00\x00\x00\x01\x00\x06\x00\xff\xff\xff\xff\x04\x00\x00\x00\xff\xff\xff\xff\x10\x00\x07\x00\xff\xff\xff\xff
\x00\x00\x00\xff\xff\xff\xff", 132) = 36
setxattr("config", "system.posix_acl_access",
"\x02\x00\x00\x00\x01\x00\x02\x00\xff\xff\xff\xff\x04\x00\x00\x00\xff\xff\xff\xff\x10\x00\x00\x00\xff\xff\xff\xff
\x00\x00\x00\xff\xff\xff\xff", 36, 0) = -1 EOPNOTSUPP (Operation not
supported)



3.nfs4_getfacl config    //fail
Operation to request attribute not supported.

//strace output
stat("config", {st_mode=getxattr("config", "system.posix_acl_access",
"\x02\x00\x00\x00\x01\x00\x06\x00\xff\xff\xff\xff\x04\x00\x00\x00\xff\xff\xff\xff\x10\x00\x07\x00\xff\xff\xff\xff
\x00\x00\x00\xff\xff\xff\xff", 132) = 36
S_IFREG|0600, st_size=66, ...}) = 0
getxattr("config", "system.nfs4_acl", 0x0, 0) = -1 EOPNOTSUPP (Operation
not supported)


4.nfs4_setfacl -a  A::hwu9 at linux-lab.cs.stevens.edu:RW config  //fail
Operation to request attribute not supported.
Failed to instantiate ACL.

//strace output
getxattr("/home/hwu9/cs631/git.sws/config", "system.nfs4_acl", 0x0, 0) = -1
EOPNOTSUPP (Operation not supported)


any ideas?

Thanks,
-Hao
