open.
Since the catia translation is implemented for open, it should not
also be done in createfile. By removing createfile from catia,
translation is now done correctly for the primary open path.
In order to support systems that have custom createfile
implementations that don't eventually call SMB_VFS_OPEN,
SMB_VFS_TRANSLATE_NAME has been expanded to take an additional
argument that specifies direction.

This vop is designed to work in tandem with SMB_VFS_READDIR to allow
vfs modules to make modifications to arbitrary filenames before
they're consumed by callers. Subsequently the core directory
enumeration code in smbd is now changed to free the memory that may be
allocated in a module. This vop enables the new version of catia in
the following patch.

This patch introduces two new temporary helper functions
vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me
to call the new smb_filename version of stat, while avoiding plumbing
it through callers that are still too inconvenient. As the conversion
moves along, I will be able to remove callers of this, with the goal
being to remove all callers.
There was also a bug in create_synthetic_smb_fname_split (also a
temporary utility function) that caused it to incorrectly handle
filenames with ':'s in them when in posix mode. This is now fixed.

smb_filename struct
Some of the callers required minimal changes, while others
(copy_internals) required significant changes. The task is simplified
a little bit because we are able to do operations and checks on the
base_name when a stream isn't used.
This patch should cause no functional changes.

This is required for the shadow_copy2 module and "wide links = no". The file
system snapshots by nature are typically outside of share directory. So the
REALPATH result fails the wide links = no test.

This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

This is to be able to provide more specific error messages.

* this allows VFS implementations that prefetch stat information on
readdir to return it through one VFS call
* backwards compatibility is maintained by passing in NULL
* if the system readdir doesn't return stat info, the stat struct is
set to invalid

This replaces release_level2_oplocks_on_change with
contend_level2_oplock_begin/end in order to contend level2 oplocks
throughout an operation rather than just at the begining. This is
necessary for some kernel oplock implementations, and also lays the
groundwork for better correctness in Samba's standard level2 oplock
handling. The next step for non-kernel oplocks is to add additional
state to the share mode lock struct that prevents any new opens from
granting oplocks while a contending operation is in progress.
All operations that contend level 2 oplocks are now correctly spanned
except for aio and synchronous writes. The two write paths both have
non-trivial error paths that need extra care to get right.
RAW-OPLOCK and the rest of 'make test' are still passing with this
change.

I'm not certain if the dummy pointer is needed in struct vfs_fsp_data,
but I added it to be consistent with the comment below.

The goal is to move all this variables into a big context structure.

This is a more general API that caches data with a LRU scheme. See
include/cache.h. No comments yet, I'm still working on it. But Jeremy has given
me a hint in one of his checkins that he would like to make use of this now.
The idea is that we get rid of all our silly little caches and merge them all
into one cache that we can then very easily trim, for example even with a
smbcontrol message if someone decides memory is tight. The main user is the
stat cache, this patch also converts the getwd cache. More caches to come.

value will be left in the socket buffer for later handling
with recvfile (or userspace equivalent). Definition of
recvfile for your system is left as an exercise for
the reader (I'm working on getting splice working :-).

Right now I'm testing a vfs object. I can't right now in make test, because
"vfs objects" assumes the .so files to be in $libdir/vfs. This patch parses the
module name out of the object name in case it starts with "/". The module name
is assumed to be the last path component's basename.
