Bug#360669: linux-2.6: CIFS mounts against servers which require packet signing (eg. Win2K3) cannot read files



Package: linux-2.6
Severity: normal
Tags: patch
Version: 2.6.16-4

Basically, the CIFS in 2.6.16 fails to sign packets properly when
reading files. This is a regression against 2.6.15.

The upstream author's GIT tree has a patch [1] which he states in [2]
that he will push upstream ASAP, and [3] suggests it as a 2.6.16.2
possibility.

As a workaround, apparently SMBFS still works, but that'll break unicode
and other CIFS improvements over SMB.

Just by the by, at [4] you can see a couple of small patchsets to
prevent heavy-load oopses in CIFS. I presume they're going upstream, but
can't say for sure how soon, and if they're candidates for Debian's
kernel. They're short though, so they might even be 2.6.16.2 fodder
too...
