* cifs: fix error handling in mount-time DFS referral chasing codeJeff Layton2009-07-281-3/+9
| | | | | | | | | | | | If the referral is malformed or the hostname can't be resolved, then the current code generates an oops. Fix it to handle these errors gracefully.

* [CIFS] make sure that DFS pathnames are properly formedSteve French2008-12-261-12/+36
| | | | | | | | | | | | | | | | | | | | | | The paths in a DFS request are supposed to only have a single preceding backslash, but we are sending them with a double backslash. This is exposing a bug in Windows where it also sends a path in the response that has a double backslash. The existing code that builds the mount option string however expects a double backslash prefix in a couple of places when it tries to use the path returned by build_path_from_dentry. Fix compose_mount_options to expect properly formed DFS paths (single backslash at front). Also clean up error handling in that function. There was a possible NULL pointer dereference and situations where a partially built option string would be returned. Tested against Samba 3.0.28-ish server and Samba 3.3 and Win2k8.

* Fixed parsing of mount options when doing DFS submountIgor Mammedov2008-11-181-24/+47
| | | | | | | | | | | | | Since these hit the same routines, and are relatively small, it is easier to review them as one patch. Fixed incorrect handling of the last option in some cases Fixed prefixpath handling convert path_consumed into host depended string length (in bytes) Use non default separator if it is provided in the original mount options Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Igor Mammedov <niallain@gmail.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

| * Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck2008-02-141-11/+12

In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
