Since there are only 19 command codes, it also is easier to track by exact command code than it was for cifs. Signed-off-by: NPavel Shilovsky <pshilovsky@samba.org> Signed-off-by: NSteve French <smfrench@gmail.com>

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.

Split all requests to echos, oplocks and others - each group uses its own credit slot. This is indicated by new flags CIFS_ECHO_OP and CIFS_OBREAK_OP that are not used now for CIFS. This change is required to support SMB2 protocol because of different processing of these commands.

struct file_lock is pretty large, so we really don't want that on the stack in a potentially long call chain. Reorganize the arguments to CIFSSMBPosixLock to eliminate the need for that. Eliminate the get_flag and simply use a non-NULL pLockInfo to indicate that this is a "get" operation. In order to do that, need to add a new loff_t argument for the start_offset.

Calling key_revoke here isn't ideal as further requests for the key will end up returning -EKEYREVOKED until it gets purged from the cache.

The only checks of the long argument passed to fcntl(fd,F_SETLEASE,.) are done after converting the long to an int. Thus some illegal values may be let through and cause problems in later code. [ They actually *don't* cause problems in mainline, as of Dave Jones's commit 8d657eb3 "Remove easily user-triggerable BUG from generic_setlease", but we should fix this anyway. And this patch will be necessary to fix real bugs on earlier kernels. ] Cc: stable@vger.kernel.org Signed-off-by: NJ.

Pull the big VFS changes from Al Viro: "This one is *big* and changes quite a few things around VFS. What's in there: - the first of two really major architecture changes - death to open intents. The former is finally there; it was very long in making, but with Miklos getting through really hard and messy final push in fs/namei.c, we finally have it. Unlike his variant, this one doesn't introduce struct opendata; what we have instead is ->atomic_open() taking preallocated struct file * and passing everything via its fields. Instead of returning struct file *, it returns -E... on error, 0 on success and 1 in "deal with it yourself" case (e.g. symlink found on server, etc.). See comments before fs/namei.c:atomic_open(). That made a lot of goodies finally possible and quite a few are in that pile: ->lookup(), ->d_revalidate() and ->create() do not get struct nameidata * anymore; ->lookup() and ->d_revalidate() get lookup flags instead, ->create() gets "do we want it exclusive" flag. With the introduction of new helper (kern_path_locked()) we are rid of all struct nameidata instances outside of fs/namei.c; it's still visible in namei.h, but not for long. Come the next cycle, declaration will move either to fs/internal.h or to fs/namei.c itself. [me, miklos, hch] - The second major change: behaviour of final fput(). Now we have __fput() done without any locks held by caller *and* not from deep in call stack. That obviously lifts a lot of constraints on the locking in there. Moreover, it's legal now to call fput() from atomic contexts (which has immediately simplified life for aio.c). We also don't need anti-recursion logics in __scm_destroy() anymore. There is a price, though - the damn thing has become partially asynchronous. For fput() from normal process we are guaranteed that pending __fput() will be done before the caller returns to userland, exits or gets stopped for ptrace. For kernel threads and atomic contexts it's done via schedule_work(), so theoretically we might need a way to make sure it's finished; so far only one such place had been found, but there might be more. There's flush_delayed_fput() (do all pending __fput()) and there's __fput_sync() (fput() analog doing __fput() immediately). I hope we won't need them often; see warnings in fs/file_table.c for details. [me, based on task_work series from Oleg merged last cycle] - sync series from Jan - large part of "death to sync_supers()" work from Artem; the only bits missing here are exofs and ext4 ones. As far as I understand, those are going via the exofs and ext4 trees resp.; once they are in, we can put ->write_super() to the rest, along with the thread calling it. - preparatory bits from unionmount series (from dhowells). - assorted cleanups and fixes all over the place, as usual. This is not the last pile for this cycle; there's at least jlayton's ESTALE work and fsfreeze series (the latter - in dire need of fixes, so I'm not sure it'll make the cut this cycle). I'll probably throw symlink/hardlink restrictions stuff from Kees into the next pile, too. Plus there's a lot of misc patches I hadn't thrown into that one - it's large enough as it is..." * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (127 commits) ext4: switch EXT4_IOC_RESIZE_FS to mnt_want_write_file() btrfs: switch btrfs_ioctl_balance() to mnt_want_write_file() switch dentry_open() to struct path, make it grab references itself spufs: shift dget/mntget towards dentry_open() zoran: don't bother with struct file * in zoran_map ecryptfs: don't reinvent the wheels, please - use struct completion don't expose I_NEW inodes via dentry->d_inode tidy up namei.c a bit unobfuscate follow_up() a bit ext3: pass custom EOF to generic_file_llseek_size() ext4: use core vfs llseek code for dir seeks vfs: allow custom EOF in generic_file_llseek code vfs: Avoid unnecessary WB_SYNC_NONE writeback during sys_sync and reorder sync passes vfs: Remove unnecessary flushing of block devices vfs: Make sys_sync writeout also block device inodes vfs: Create function for iterating over block devices vfs: Reorder operations during sys_sync quota: Move quota syncing to ->sync_fs method quota: Split dquot_quota_sync() to writeback and cache flushing part vfs: Move noop_backing_dev_info check from sync into writeback ...
