Problems with default ACLs over NFS

[J.A. MagallÃn]

Hi all...

I have a strange problem with 2.6.29-rc8-git3.
It looks like a kernel bug... ?

I have a box with NFS autofs-mounted home directories. Server is a
Solaris 10 system. This worked in previous kernel versions, so I
don't blame Solaris, at this moment.

With this acls set in my home:


prometeo:~> getfacl .  

# file: .
# owner: magallon
# group: giga
user::rwx
user:webservd:r-x       #effective:r-x
group::--x      #effective:--x
mask:r-x
other:--x
default:user::rwx
default:group::--x
default:other:--x

I get this strange message in the linux client:

cicely:~> mkdir kk  
mkdir: cannot create directory `kk': Invalid argument

But the directory is created, and its ACLs are correct:

prometeo:~> getfacl kk  

# file: kk
# owner: magallon
# group: giga
user::rwx
group::--x      #effective:--x
other:--x
default:user::rwx
default:group::--x
default:other:--x

If I remove the 'default' entries, the error message goes away.

With strace, I get this:

mkdir("kk", 0777)                       = -1 EINVAL (Invalid argument)

Mount info from /proc/mounts:

ldap:danae-nfs:automountMapName=auto_home,o=diis /home autofs rw,fd=7,pgrp=3165,timeout=600,minproto=5,maxproto=5,indirect 0 0

danae-nfs:/export/home/usuarios/giga/magallon /home/magallon nfs rw,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,nointr,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=155.210.152.202,mountvers=3,mountproto=tcp,addr=155.210.152.202 0 0

It happens the same If I try to create a file with "> kk", or try to cp -r one
other dir, but "touch kk" works.

Any idea ?

TIA
