When a share is mounted using no username, cifs_mount sets volume_info.username as a NULL pointer, and the sesInfo userName as an empty string. The volume_info.username is passed to a couple of other functions to see if there is an existing unc or tcp connection that can be used. These functions assume that the username will be a valid string that can be passed to strncmp. If the pointer is NULL, then the kernel will oops if there's an existing session to which the string can be compared. This patch changes cifs_mount to set volume_info.username to an empty string in this situation, which prevents the oops and should make it so that the comparison to other null auth sessions match.

When mounted with cifsacl mount option, readdir can not instantiate the inode with the estimated mode based on the ACL for each file since we have not queried for the ACL for each of these files yet. So set the refresh time to zero for these inodes so that the next stat will cause the client to go to the server for the ACL info so we can build the estimated mode (this means we also will issue an extra QueryPathInfo if the stat happens within 1 second, but this is trivial compared to the time required to open/getacl/close for each). ls -l is slower when cifsacl mount option is specified, but displays correct mode information.

When mounted with the cifsacl mount option, we were treating any deny ACEs found like allow ACEs and it turns out for SFU and SUA Windows set these type of access control entries often. The order of ACEs is important too. The canonical order that most ACL tools and Windows explorer consruct ACLs with is to begin with DENY entries then follow with ALLOW, otherwise an allow entry could be encountered first, making the subsequent deny entry like "dead code which would be superflous since Windows stops when a match is made for the operation you are trying to perform for your user We start with no permissions in the mode and build up as we find permissions (ie allow ACEs). This fixes deny ACEs so they affect the mask used to set the subsequent allow ACEs. Acked-by:

Also, fix the parser to recognize them and set the secType accordingly. Make CIFSSMBNegotiate not error out automatically after parsing the securityBlob. Also thanks to Q (Igor) and Simo for their help on this set of kerberos patches (and Dave Howells for help on the upcall). Signed-off-by:

Add routines to handle upcalls to userspace via keyctl for the purpose of getting a SPNEGO blob for a particular uid and server combination. Clean up the Makefile a bit and set it up to only compile cifs_spnego if CONFIG_CIFS_UPCALL is set. Also change CONFIG_CIFS_UPCALL to depend on CONFIG_KEYS rather than CONFIG_CONNECTOR. cifs_spnego.h defines the communications between kernel and userspace and is intended to be shared with userspace programs.

Kernel bugzilla bug #9228 If mount helper (mount.cifs) missing, mounts with form like //10.11.12.13/c$ would not work (only mounts with slash e.g. //10.11.12.13\\c$ would work) due to problem with slash supposed to be converted to backslash by the mount helper (which is not there). If we fail on converting an IPv4 address in in4_pton then try to canonicalize the first slash (ie between sharename and host ip address) if necessary. If we have to retry to check for IPv6 address the slash is already converted if necessary. Signed-off-by:

We were requesting GENERIC_READ but that fails when we do not have read permission on the file (even if we could read the ACL). Also move the dump access control entry code into debug ifdef. Signed-off-by:

This path mustn't have been tested :( I did attempt to exercise it by injecting failures here, but I suspect PageMappedToDisk may have been getting in the way. Will need more of a look, although I think nobh mode is OK for an -rc1 (it shouldn't eat anyone's data). Commit 03158cd7 ("fs: restore nobh") introcduced a NULL deref.
