Description Jeff Layton 2010-02-08 20:04:42 UTC

+++ This bug was initially created as a clone of Bug #562788 +++

Upstream has has a rash of elusive problem reports in the last several months with CIFS. I finally was able to get a reproducer and track down the cause of at least one of them.

http://git.kernel.org/?p=linux/kernel/git/sfrench/cifs-2.6.git;a=commitdiff;h=f12f98dba6ea1517cd7fbb912208893b9c014c15

...I also have a patch queued up to fix the way dentries are hashed in the readdir code for case-insensitive mounts.

Comment 1 Jeff Layton 2010-02-08 20:05:51 UTC

Note that these bugs are generally papered over on RHEL5 by the fact that "noserverino" is the default there.

Comment 2 Jeff Layton 2010-02-12 14:21:50 UTC

Setting blocker flag and changing this to a more generic title.

Comment 4 Jeff Layton 2010-02-12 14:37:46 UTC

I'd like to see these patches make 5.5. They just hit mainline a day or two ago, but are small fixes and probably ought to go in.

    BZ#562947: cifs: fix dentry hash calculation for case-insensitive mounts
    BZ#562947: CIFS shouldn't make mountpoints shrinkable
    BZ#562947: [CIFS] Maximum username length check in session setup does not match
