mount.cifs fails with "cannot allocate memory"

[Michael Stevens]

Binary package hint: samba

mstevens@mstevens-desktop:/export % lsb_release -rd
Description: Ubuntu 10.04 LTS
Release: 10.04

mstevens@mstevens-desktop:/export % uname -a
Linux mstevens-desktop 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 i686 GNU/Linux

Trying to mount a CIFS share with mount.cifs gives an "out of memory" error:

mstevens@mstevens-desktop:/export % sudo mount -t cifs -o credentials=/etc/cifs.credentials,rw,nodev,noexec,nosuid,uid=mstevens,gid=mstevens '\\files.local\backup' /export/backup
mount error(12): Cannot allocate memory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Other shares on the same server can be correctly mounted.

dmesg contains:

[1493914.423643] CIFS VFS: Send error in QFSAttributeInfo = -5
[1493914.424928] CIFS VFS: cifs_read_super: get root inode failed

which may be related.

What version are you copying from?

[Michael Stevens (mstevens-etla-deactivatedaccount)]

Server is a ReadyNAS Duo running RAIDiator 4.1.6 [1.00a043].

Client is Ubuntu 10.04 x86.

On further experiment I was able to fix the problem by deleting and recreating the share on the server.

This appears to be resolved in Ubuntu server bug #570456 if I am reading the thread correctly:

http://<email address hidden>/msg38649.html

Seems there is an unimplemented cp15 register write (c9, c12, {0, 0}) with Ubuntu OMAP image that is at the root of the issue and is fixed in Maverick's qemu-kvm package.

Perhaps I'm being dumb, but I can't see the relevance?

You're not being dumb - my mistake. I managed to find the issue locally. The two are unrelated as the issue actually traced down to a misconfigured share in AD and not the same issue as above. Call this one a "mea culpa" - and never mind the report.
