the fun thing is that i can cd to a lower level directory, and ls

fine there! only the mount point has the problem

Re: [3.0.0+][Regression][Bisected] CIFS: getdents() broken for
large dirs
Hmmm, maybe. What makes you think that it's related? What sort of
server are you seeing this against?
Windows XP service pack 2 (greek)
How many files are in the directory?
140 folders and 20 files
Attached is a tcp dump of my session.
I tried reproducing this here, but wasn't able to. Testing against my
xp box worked fine.
Most likely, the FIND_FILE responses are falling afoul of the code in
coalesce_t2 or check2ndT2. Unfortunately that code is pretty
complicated and I'm not certain what the problem actually is...
One thing that's interesting is that the total data being sent in the
request is rather large (16336 bytes). I think that's legit, but maybe
it's exceeding the end of the buffer once we try to coalesce it.
Would it be possible to get the cFYI output from this test?
I did not get a cFYI output from that test, but i redid a mount-ls-umount
and am attaching the tcpdump
Also here http://pastebin.com/J20uC6kU you can find the cifsFYI and the
contents of /proc/fs/cifs/DebugData form the same test
Is this a regression? Did it work with earlier kernels and only
recently start failing?
I do not know, and i am a bit afraid to downgrade this machine below 3.0
due to some changes arch linux has introduced recently. I can always set up
a few virtual machines though, and i can even request permission from my
company to give you shell access if you like. Which kernel versions would
you like me to test?
I just tested 3.1.5-1-ARCH on a virtual machine and it works, so it is
probably a regression... On the same virtual machine 3.2-rc7 produces
input/output error. The virtual machine is a fresh install of arch linux.
here is the relevant pastebin http://pastebin.com/BwX2DqJC
and attached is the tcpdump
As a am a noob to all this, what should I do next in order to help you?
maybe compile a 3.1 kernel from official sources to make sure no patches
from arch linux interfere?
It is the same request from the cifs client in both the successful and
unsuccessful cases. trans2, findfirst2, infolevel of 261 and search count
of 150.
So nothing has changed from what is emanating from cifs client.
In the error case, Windows XP responds with search count of 142 whereas
in successful case, Windows XP responds with search count of significantly
less number, e.g. 36.
Are files/directories in jobs directory less now i.e. has anything changed
in this directory on the server 192.168.0.11 i.e. have files been deleted,
directories removed etc. since the failure was noticed the very first time?
there are some changes in the jobs directory since the failure was
noticed, but they are quite minor. at most one folder was deleted and
one was added, and the pdf files in the root dir (1_B_MAYRO.pdf 1XR.pdf
....7_B_MAYRO.pdf ) were overwritten, +- one or two files.
