Description Walkie 2006-10-29 07:09:19 UTC
ls returns
ls: reading directory .: Invalid argument
on cifs mounted volume on directories with many files+directories (tested 105 number is ok, more gets error)
and orter methods to stat that directory also non-funcctionsl
server uses FC5 samba3.0.21b-2 client is FC6 samba 3.0.23c-2
when client was FC5 samba 3.0.23c-2 everything works fine
Comment 1 Timothee Besset 2007-01-15 10:52:30 UTC
I am experiencing something very similar, with directories that have respectively  159, 124 and 175 files in them. Likely all the directories in the tree that have a  higher file count.

The client is running up to date FC5 (kernel version: 2.6.18-1.2200.fc5), I have no idea what the server is (a Windows box probably). man mount.cifs says cifs version 1.39

Going to see about upgrading to latest.

Comment 2 Timothee Besset 2007-01-15 11:00:07 UTC
I mistakenly reported version 1.39, looks like it's 1.45:

trace of an ls /mount/baddirectory operation

A trace of an ls performed on one of those bad directories. It loops through the files, the only thing I can notice is this at the end:

 fs/cifs/readdir.c: filldir rc = -22
 fs/cifs/readdir.c: new entry ea1f51ac old entry ea1f514c
 fs/cifs/readdir.c: CIFS VFS: leaving cifs_readdir (xid = 16530490) rc = -22

moving to cifsvfs. I guess this is long fixed and should be closed, right?
Comment 7 Ronnie Sahlberg 2022-05-12 22:30:00 UTC
This was fixed more than a decade ago. Lets close it.
