[Kernel-packages] [Bug 1242713] Re: NFSv3 hangs when using ACLs and KRB5 with linux-image-generic-lts-raring
I am happy for the bug report to be closed as 14.04LTS has fixed the
problem and there is also now a 12.04LTS hardware update kernel that
does not have the problem.

NFSv3 hangs when using ACLs and KRB5 with linux-image-generic-lts-
raring
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I was testing upgrading some computers to 12.04.3 (with the LTS raring
kernel - 3.8.0) and came across a problem with NFSv3/ACLs and KRB5
security. Any access to the NFS mounted filesystem that tries to
access the access control list (ACL) hangs.
The NFS server is running 12.04.3 with the normal 3.2.0 kernel.
I mount the filesystem using:
mount -o nfsvers=3,tcp,sec=krb5 fileserver:/export/home /home
and it mounts fine.
Afterwards though, if you try and do something simple such as an 'ls -l
/home' then it hangs. Using strace to see why the ls -l hangs reveals that it
is hanging at

lstat(/home/student, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lgetxattr(/home/student, security.selinux, 0xc77ea0, 255) = -1 EOPNOTSUPP
(Operation not supported)
lgetxattr(/home/student, system.posix_acl_access
It all works fine if you either use the noacl mount option or remove
the sec=krb5 mount option.
I have tried using 13.04 as the client and it has the same problem. I
can also confirm that the problem exists with using the LTS raring
kernel on the server. The LTS quantal kernel (3.5.0) as the client
works fine.

Ian Gordon, could you please confirm this issue exists on your client
with the latest development release of Ubuntu? ISO images are available
from http://cdimage.ubuntu.com/daily-live/current/ . If the issue
remains, could you please run the following command in the development

updated debug information to this report:

I can also state that NFSv3 still hangs when using ubuntu 13.10 as the nfs

It also still hangs when using the mainline kernel 3.8.13-03081311-generic
The mainline kernel 3.12.0-031200rc6-generic seems to work fine.

[Kernel-packages] [Bug 1242713] Re: NFSv3 hangs when using ACLs and KRB5 with linux-image-generic-lts-raring
If this hangs in an lsgetxattr() syscall with the raring kernel but not
when using the quantal kernel with the same userspace, then I think this
is clearly a kernel issue. Reassigning.
FWIW I never saw this issue here with the raring kernel, but all of my
krb5 NFS mounts are v4.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.12 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot,
please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as
Confirmed.
Thanks in advance.

Title:
NFSv3 hangs when using ACLs and KRB5 with linux-image-generic-lts-
raring
Status in “linux” package in Ubuntu:
Incomplete
Status in “linux-lts-raring” package in Ubuntu:
New
Bug description:
I was testing upgrading some computers to 12.04.3 (with the LTS raring
kernel - 3.8.0) and came across a problem with NFSv3/ACLs and KRB5
security. Any access to the NFS mounted filesystem that tries to
access the access control list (ACL) hangs.
The NFS server is running 12.04.3 with the normal 3.2.0 kernel.
I mount the filesystem using:
mount -o nfsvers=3,tcp,sec=krb5 fileserver:/export/home /home
and it mounts fine.
Afterwards though, if you try and do something simple such as an 'ls -l
/home' then it hangs. Using strace to see why the ls -l hangs reveals that it
is hanging at
.
lstat(/home/student, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lgetxattr(/home/student, security.selinux, 0xc77ea0, 255) = -1 EOPNOTSUPP
(Operation not supported)
lgetxattr(/home/student, system.posix_acl_access
It all works fine if you either use the noacl mount option or remove
the sec=krb5 mount option.
I have tried using 13.04 as the client and it has the same problem. I
can also confirm that the problem exists with using the LTS raring
kernel on the server. The LTS quantal kernel (3.5.0) as the client
works fine.
