* cifs: fix noserverino handling when unix extensions are enabledJeff Layton2010-05-171-0/+1
| | | | | | | | | The uniqueid field sent by the server when unix extensions are enabled is currently used sometimes when it shouldn't be. The readdir codepath is correct, but most others are not.

* cifs: clean up handling when server doesn't consistently support inode numbersJeff Layton2009-11-061-0/+1
| | | | | | | | | | | | | | | | | | It's possible that a server will return a valid FileID when we query the FILE_INTERNAL_INFO for the root inode, but then zeroed out inode numbers when we do a FindFile with an infolevel of SMB_FIND_FILE_ID_FULL_DIR_INFO. In this situation turn off querying for server inode numbers, generate a warning for the user and just generate an inode number using iunique. Once we generate any inode number with iunique we can no longer use any server inode numbers or we risk collisions, so ensure that we don't do that in cifs_get_inode_info either.

* cifs: convert oplock breaks to use slow_work facility (try #4)Jeff Layton2009-09-241-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the fourth respin of the patch to convert oplock breaks to use the slow_work facility. A customer of ours was testing a backport of one of the earlier patchsets, and hit a "Busy inodes after umount..." problem. An oplock break job had raced with a umount, and the superblock got torn down and its memory reused. When the oplock break job tried to dereference the inode->i_sb, the kernel oopsed. This patchset has the oplock break job hold an inode and vfsmount reference until the oplock break completes. With this, there should be no need to take a tcon reference (the vfsmount implicitly holds one already). Currently, when an oplock break comes in there's a chance that the oplock break job won't occur if the allocation of the oplock_q_entry fails. There are also some rather nasty races in the allocation and handling these structs. Rather than allocating oplock queue entries when an oplock break comes in, add a few extra fields to the cifsFileInfo struct. Get rid of the dedicated cifs_oplock_thread as well and queue the oplock break job to the slow_work thread pool. This approach also has the advantage that the oplock break jobs can potentially run in parallel rather than be serialized like they are today.

* cifs: fix oplock request handling in posix codepathJeff Layton2009-09-151-1/+1
| | | | | | | | | | | | | | | | cifs_posix_open takes a "poplock" argument that's intended to be used in the actual posix open call to set the "Flags" field. It ignores this value however and declares an "oplock" parameter on the stack that it passes uninitialized to the CIFSPOSIXOpen function. Not only does this mean that the oplock request flags are bogus, but the result that's expected to be in that variable is unchanged. Fix this, and also clean up the type of the oplock parameter used. Since it's expected to be __u32, we should use that everywhere and not implicitly cast it from a signed type.

* cifs: add new cifs_iget function and convert unix codepath to use itJeff Layton2009-07-011-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs: add new cifs_iget function and convert unix codepath to use it In order to unify some codepaths, introduce a common cifs_fattr struct for storing inode attributes. The different codepaths (unix, legacy, normal, etc...) can fill out this struct with inode info. It can then be passed as an arg to a common set of routines to get and update inodes. Add a new cifs_iget function that uses iget5_locked to identify inodes. This will compare inodes based on the uniqueid value in a cifs_fattr struct. Rather than filling out an already-created inode, have cifs_get_inode_info_unix instead fill out cifs_fattr and hand that off to cifs_iget. cifs_iget can then properly look for hardlinked inodes. On the readdir side, add a new cifs_readdir_lookup function that spawns populated dentries. Redefine FILE_UNIX_INFO so that it's basically a FILE_UNIX_BASIC_INFO that has a few fields wrapped around it. This allows us to more easily use the same function for filling out the fattr as the non-readdir codepath. With this, we should then have proper hardlink detection and can eventually get rid of some nasty CIFS-specific hacks for handing them.

* [CIFS] Reduce number of socket retries in large write pathSteve French2008-10-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | CIFS in some heavy stress conditions cifs could get EAGAIN repeatedly in smb_send2 which led to repeated retries and eventually failure of large writes which could lead to data corruption. There are three changes that were suggested by various network developers: 1) convert cifs from non-blocking to blocking tcp sendmsg (we left in the retry on failure) 2) change cifs to not set sendbuf and rcvbuf size for the socket (let tcp autotune the buffer sizes since that works much better in the TCP stack now) 3) if we have a partial frame sent in smb_send2, mark the tcp session as invalid (close the socket and reconnect) so we do not corrupt the remaining part of the SMB with the beginning of the next SMB. This does not appear to hurt performance measurably and has been run in various scenarios, but it definately removes a corruption that we were seeing in some high stress test cases.

* [CIFS] Fix oops when slow oplock process races with unmountSteve French2008-04-151-0/+1
| | | | | | | | | | If a tcon is being freed in call tconInfoFree, clean up any entries that may exist in global oplock queue as the tcon structure hanging off of those entries will be invalid and can cause oops while accesing any elements in the tcon structure.

* [CIFS] file create with acl support enabled is slowSteve French2008-03-141-2/+3
| | | | | | | | | | | | | | | | Shirish Pargaonkar noted: With cifsacl mount option, when a file is created on the Windows server, exclusive oplock is broken right away because the get cifs acl code again opens the file to obtain security descriptor. The client does not have the newly created file handle or inode in any of its lists yet so it does not respond to oplock break and server waits for its duration and then responds to the second open. This slows down file creation signficantly. The fix is to pass the file descriptor to the get cifsacl code wherever available so that get cifs acl code does not send second open (NT Create ANDX) and oplock is not broken.
