2011-05-19cifs: Simplify handling of submount options in cifs_mount.Sean Finney1-13/+11
With CONFIG_DFS_UPCALL enabled, maintain the submount options in cifs_sb->mountdata, simplifying the code just a bit as well as making corner-case allocation problems less likely.

2011-05-19cifs: cifs_parse_mount_options: do not tokenize mount options in-placeSean Finney1-35/+74
To keep strings passed to cifs_parse_mount_options re-usable (which is needed to clean up the DFS referral handling), tokenize a copy of the mount options instead. If values are needed from this tokenized string, they too must be duplicated (previously, some options were copied and others duplicated). Since we are not on the critical path and any cleanup is relatively easy, the extra memory usage shouldn't be a problem (and it is a bit simpler than trying to implement something smarter).

2011-05-19cifs: Add support for mounting Windows 2008 DFS sharesSean Finney1-0/+18
Windows 2008 CIFS servers do not always return PATH_NOT_COVERED when attempting to access a DFS share. Therefore, when checking for remote shares, unconditionally ask for a DFS referral for the UNC (w/out prepath) before continuing with previous behavior of attempting to access the UNC + prepath and checking for PATH_NOT_COVERED.

2011-05-19cifs: turn BCC into a static inlined functionJeff Layton1-3/+6
It's a bad idea to have macro functions that reference variables more than once, as the arguments could have side effects. Turn BCC() into a static inlined function instead. While we're at it, make it return a void * to discourage anyone from dereferencing it as-is.

2011-05-19cifs: keep BCC in little-endian formatJeff Layton9-82/+41
This is the same patch as originally posted, just with some merge conflicts fixed up... Currently, the ByteCount is usually converted to host-endian on receive. This is confusing however, as we need to keep two sets of routines for accessing it, and keep track of when to use each routine. Munging received packets like this also limits when the signature can be calulated. Simplify the code by keeping the received ByteCount in little-endian format. This allows us to eliminate a set of routines for accessing it and we can now drop the *_le suffixes from the accessor functions since that's now implied. While we're at it, switch all of the places that read the ByteCount directly to use the get_bcc inline which should also clean up some unaligned accesses.

2011-05-19consistently use smb_buf_length as be32 for cifs (try 3)Steve French7-101/+102
There is one big endian field in the cifs protocol, the RFC1001 length, which cifs code (unlike in the smb2 code) had been handling as u32 until the last possible moment, when it was converted to be32 (its native form) before sending on the wire. To remove the last sparse endian warning, and to make this consistent with the smb2 implementation (which always treats the fields in their native size and endianness), convert all uses of smb_buf_length to be32. This version incorporates Christoph's comment about using be32_add_cpu, and fixes a typo in the second version of the patch.

2011-05-19cifs: Invoke id mapping functions (try #17 repost)Shirish Pargaonkar2-24/+325
rb tree search and insertion routines. A SID which needs to be mapped, is looked up in one of the rb trees depending on whether SID is either owner or group SID. If found in the tree, a (mapped) id from that node is assigned to uid or gid as appropriate. If unmapped, an upcall is attempted to map the SID to an id. If upcall is successful, node is marked as mapped. If upcall fails, node stays marked as unmapped and a mapping is attempted again only after an arbitrary time period has passed. To map a SID, which can be either a Owner SID or a Group SID, key description starts with the string "os" or "gs" followed by SID converted to a string. Without "os" or "gs", cifs.upcall does not know whether SID needs to be mapped to either an uid or a gid. Nodes in rb tree have fields to prevent multiple upcalls for a SID. Searching, adding, and removing nodes is done within global locks. Whenever a node is either found or inserted in a tree, a reference is taken on that node. Shrinker routine prunes a node if it has expired but does not prune an expired node if its refcount is not zero (i.e. sid/id of that node is_being/will_be accessed). Thus a node, if its SID needs to be mapped by making an upcall, can safely stay and its fields accessed without shrinker pruning it. A reference (refcount) is put on the node without holding the spinlock but a reference is get on the node by holding the spinlock. Every time an existing mapped node is accessed or mapping is attempted, its timestamp is updated to prevent it from getting erased or a to prevent multiple unnecessary repeat mapping retries respectively. For now, cifs.upcall is only used to map a SID to an id (uid or gid) but it would be used to obtain an SID for an id.

2011-05-19Introduce smb2 mounts as vers=2Steve French1-0/+17
As with Linux nfs client, which uses "nfsvers=" or "vers=" to indicate which protocol to use for mount, specifying "vers=smb2" or "vers=2" will force an smb2 mount. When vers is not specified cifs is used ie "vers=cifs" or "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.

2011-05-19Introduce SMB2 Kconfig optionSteve French1-0/+20
SMB2 is the followon to the CIFS (and SMB) protocols and the default for Windows since Windows Vista, and also now implemented by various non-Windows servers. SMB2 is more secure, has various performance advantages, including larger i/o sizes, flow control, better caching model and more. SMB2 also resolves some scalability limits in the cifs protocol and adds many new features while being much simpler (only a few dozen commands instead of hundreds) and since the protocol is clearer it is also more consistently implemented across servers and thus easier to optimize. After much discussion with Jeff Layton, Jeremy Allison and others at Connectathon, we decided to move the smb2 code from a distinct .ko and fstype into distinct C files that optionally build in cifs.ko. As a result the Kconfig gets simpler. To avoid destabilizing cifs, the smb2 code is going to be moved into its own experimental CONFIG_CIFS_SMB2 ifdef as it is merged and rereviewed. The changes to stable cifs (builds with the smb2 ifdef off) are expected to be fairly small. Reviewed-by: Jeff Layton <[email protected]> Signed-off-by: Steve French <[email protected]>

2011-05-19Don't compile in unused reparse point symlink codeSteve French3-15/+14
Recent Windows versions now create symlinks more frequently and they do use this "reparse point" symlink mechanism. We can of course do symlinks nicely to Samba and other servers which support the CIFS Unix Extensions and we can also do SFU symlinks and "client only" "MF" symlinks optionally, but for recent Windows we currently can not handle the common "reparse point" symlinks fully, removing the caller for this. We will need to extend and reenable this "reparse point" worker code in cifs and fix cifs_symlink to call this. In the interim this code has been moved to its own config option so it is not compiled in by default until cifs_symlink fixed up (and tested) to use this.

2011-05-19MIPS: JZ4740: setup: Autodetect physical memory.Maarten ter Huurne1-0/+32

It is still possible to override with with the "mem=" parameter, but we have a sensible default now.
