| * cifs: fix oops while traversing open file list (try #4)Shirish Pargaonkar2012-05-232-24/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While traversing the linked list of open file handles, if the identfied file handle is invalid, a reopen is attempted and if it fails, we resume traversing where we stopped and cifs can oops while accessing invalid next element, for list might have changed. So mark the invalid file handle and attempt reopen if no valid file handle is found in rest of the list. If reopen fails, move the invalid file handle to the end of the list and start traversing the list again from the begining. Repeat this four times before giving up and returning an error if file reopen keeps failing.

| * CIFS: Introduce SMB2 mounts as vers=2.1Steve French2012-05-234-1/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Introduce SMB2 Kconfig optionSteve French2012-05-231-0/+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.

We first allocate a set of pages to hold the replies, then issue the reads in parallel and then collect the replies and copy the results into the iovec.

The false return from cifs_d_revalidate(), due to the inode now being marked with the S_AUTOMOUNT flag, might not invalidate the dentry if there is a concurrent unlazy path walk. This is because the dentry reference count will be at least 2 in this case causing d_invalidate() to return EBUSY. So the asumption that the dentry will be discarded then correctly instantiated via ->lookup() might not hold.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing, I've found that even when we are able to negotiate a much larger rsize with the server, on-the-wire reads often end up being capped at 128k because of ra_pages being capped at that level. Lifting this restriction gave almost a twofold increase in sequential read performance on my craptactular KVM test rig with a 1M rsize. I think this is safe since the actual ra_pages that the VM requests is run through max_sane_readahead() prior to submitting the I/O.
