Description Bastien Nocera 2005-11-01 09:22:38 EST
Using smbfs on a 2.6.9-11.EL kernel, with the server being a Win2k, Win2k3,
Win9x, NT4 or Samba3, when listing a directory with a large number of files, and
some long names, some files end up missing in the listing.

From the comments in RHEL4's linux-2.6.9/fs/smbfs/request.c:
         * max parameters + max data + max setup == bufsize to make NT4 happy
         * and not abort the transfer or split into multiple responses. It also
         * makes smbfs happy as handling packets larger than the buffer size
         * is extra work.
         * OS/2 is probably going to hate me for this ...

max data = bufsize - max parameters - max setup
which means:
mdata = req->rq_bufsize - SMB_TRANS2_MAX_PARAM - server->opt.max_xmit - 100; /*
the -100 being to make OS/2 happy, apparently */

The current code doesn't do that...

Adding a blocker. Work will be done on the RHEL3 version.

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update

I've not been able to reproduce this problem at all with a client running my
current peoplepage kernels. I've tried samba 3.0.25 (running on f7 and fc6), and
a win2k server. I've also tried having the script create varying amounts of
files (700, 900, 1000, and 7000). I always seem to get the correct number of
files returned.

Can you verify whether this bug is already fixed in 4.5 kernels and/or the
kernels on my peoplepage:

Comment 12 RHEL Product and Program Management 2007-09-07 15:46:57 EDT
This request was previously evaluated by Red Hat Product Management
for inclusion in the current Red Hat Enterprise Linux release, but
Red Hat was unable to resolve it in time.  This request will be
reviewed for a future Red Hat Enterprise Linux release.

Closing this BZ since there's been no activity on it for a long time and the IT
associated with it has closed. Please reopen if this is still an issue.
