cifs: Switch to generic xattr handlers

2016-04-23T19:33:03+00:00

Use xattr handlers for resolving attribute names. The amount of setup code required on cifs is nontrivial, so use the same get and set functions for all handlers, with switch statements for the different types of attributes in them. The set_EA handler can handle NULL values, so we don't need a separate removexattr function anymore. Remove the cifs_dbg statements related to xattr name resolution; they don't add much. Don't build xattr.o when CONFIG_CIFS_XATTR is not defined. Signed-off-by: Andreas Gruenbacher Signed-off-by: Al Viro

cifs: add new case-insensitive conversion routines that are based on wchar_t's

2013-09-08T19:38:05+00:00

The existing NLS case conversion routines do not appropriately handle the (now common) case where the local host is using UTF8. This is because nls_utf8 has no support at all for converting a utf8 string between cases and the NLS infrastructure in general cannot handle a multibyte input character. In any case, what we really need for cifs is to emulate how we expect the server to convert the character to upper or lowercase. Thus, even if we had routines that could handle utf8 case conversion, we likely would end up with the wrong result if the name ends up being in the upper planes. This patch adds a new scheme for doing unicode case conversion. The case conversion tables that Microsoft has published for Windows 8 have been converted to a set of lookup tables, and a routine is added to convert a wchar_t from lower to uppercase using those tables.

CIFS: Add capability to send SMB2 negotiate message

2012-07-24T17:54:55+00:00

and add negotiate request type to let set_credits know that we are only on negotiate stage and no need to make a decision about disabling echos and oplocks. Signed-off-by: Pavel Shilovsky Signed-off-by: Steve French

CIFS: Make demultiplex_thread work with SMB2 code

2012-07-24T17:54:52+00:00

Now we can process SMB2 messages: check message, get message id and wakeup awaiting routines. Signed-off-by: Pavel Shilovsky Signed-off-by: Steve French

CIFS: Map SMB2 status codes to POSIX errors

2012-07-24T15:25:15+00:00

Add mapping table for 32 bit SMB2 status codes to linux errors. Note that SMB2 does not use DOS/OS2 errors (ever) so mapping to DOS/OS2 errors as a common network subset (as we do for cifs) doesn't help. And note that the set of status codes is much more complete here. Signed-off-by: Steve French Signed-off-by: Pavel Shilovsky Signed-off-by: Steve French

CIFS: Introduce SMB2 mounts as vers=2.1

2012-05-23T08:33:15+00:00

As with Linux nfs client, which uses "nfsvers=" or "vers=" to indicate which protocol to use for mount, specifying "vers=2.1" will force an SMB2 mount. When vers is not specified CIFS is used "vers=1" We can eventually autonegotiate down from SMB2 to CIFS when SMB2 is stable enough to make it the default, but this is for the future. At that time we could also implement a "maxprotocol" mount option as smbclient and Samba have today, but that would be premature until SMB2 is stable. Intially the SMB2 Kconfig option will depend on "BROKEN" until the merge is complete, and then be "EXPERIMENTAL" When it is no longer experimental we can consider changing the default protocol to attempt first.

cifs: add a smb_version_operations/values structures and a smb_version enum

2012-05-17T01:13:34+00:00

We need a way to dispatch different operations for different versions. Behold the smb_version_operations/values structures. For now, those structures just hold the version enum value and nothing uses them. Eventually, we'll expand them to cover other operations/values as we change the callers to dispatch from here.
