They use talloc_tos() internally: hoist that up to the callers, some
of whom don't want to us talloc_tos().
A simple patch, but hits a lot of files.

schedule_aio_smb2_write can return NT_STATUS_FILE_LOCK_CONFLICT.
This is a valid error code that smb2.lock.rw-shared expects and
checks for. The code before this patch maps this to NT_STATUS_FILE_CLOSED,
masking the real, correct error message.

This boolean was only set if the old machine account store (with an
MD4 hash in it) was returned. We have not set that password type for
years. If this call ever worked, it would store a plaintext password,
so we could only ever be here if we had set a password using a version
of Samba so old as not to store plaintext, and then never honered the
flag anyway.

On open without create, the file did exist, but some
other (local or NFS) process either renamed/unlinked
and re-created the file with different dev/ino after
we walked the path, but before we did the open. We
could retry the open but it's a rare enough case it's
easier to just fail the open to prevent creating any
problems in the open file db having the wrong dev/ino
key.

Move the inheritance work into the if block
where we created the file. We can never have
created the file (and thus need no inheritance)
for a stat-open.

Move the fstat call into the block which opens a file descriptor.
Remove the stat() call in the stat-open case. We already failed
the open if !file_existed.
A few lines before we did check for x != NULL. I think this might
fix a potential remote crash.

This is currently needed for files_struct and connection_struct
that contain backlinks to smbXsrv_open and smbXsrv_tcon, respectively.
Finally, these backlinks to the smb level structures should be removed.
This makes sure we generate unique persistent file ids,
which are stored in smbXsrv_open_global.tdb.

Will allow thread-specific credentials to be added by modifying
the central definitions. Deliberately left the setXX[ug]id()
call in popt as this is not used in Samba.
If the client hasn't consumed the lowest seqnum, but the distance
between lowest and highest seqnum has reached max credits.
In that case we should stop granting credits.

This helps clarify the role of this structure and wrapper function.
The purpose here is to provide helper functions to the lib/param
loadparm_context that point back at the s3 lp_ functions. This allows
a struct loadparm_context to be passed to any point in the code, and
always refer to the correct loadparm system. If this has not been
set, the variables loaded in the lib/param code will be returned.
As requested by Michael Adam.

eff3609 moved the async signal handler initialization to later in the process
to enable aio_fork and aio_pthread on platforms without realtime signals. This
commit broke the use of the native aio interface. aio_pending_size is
initialized to 0, so aio.c will not allow async i/0 at all if modules do not
set that variable correctly. Initialize to 100 right from the start.

It seems to be important to have unique persistent file ids,
because windows clients seem to index files by server_guid + persistent_file_id.
Which may break, if we just have a 16-bit range per connection
and the client connects multiple times.
Based on code from Ira Cooper. Use fsp->fh->gen_id as the persistent
fileid in SMB2.

This calculates a 64-bit value that most likely uniquely identifies
the files_struct globally to the server.
* 32-bit random gen_id
* 16-bit truncated open_time
* 16-bit fnum (valatile_id)
Based on code from Ira Cooper. Use fsp->fh->gen_id as the persistent
fileid in SMB2.

This makes sure the value is never 0, it's between 1 and UINT32_MAX.
While fsp->fh->gen_id is 'unsigned long' currently (which might by 8 bytes),
there's some oplock code which truncates it to uint32_t (using IVAL()).
Which means we could reuse fsp->fh->gen_id as persistent file id
until we have a final fix, which uses database.
See bug #8995 for more details.
Based on code from Ira Cooper. Ensure fsp->fh->gen_id starts from
a random point. We will use this as the SMB2 persistent_id.

We "TALLOC_FREE(curr)" and assign prev=curr in the for-loop header.
This will lead to "prev"==NULL always. In this loop, we do not need
to correctly re-shuffle the linked list, we delete all from the
beginning anyway.

or should we leave the NetBSD and FreeBSD platforms just broken? Actually these
two *want* to have broken platforms as they use different errno's than POSIX
demands *interntionally*. The POSIX errno ELOOP for O_NOFOLLOW open calls on
symlinks is clear and unambiguous. See http://gnats.netbsd.org/43154 for the
interesting NetBSD discussion on that.

This moves the start of the range of valid cnum values up from 0 to CNUM_OFFSET
(currently 1), so that in a later step we can use 0 as invalid cnum value
instead of the current -1. This will allow us to change the type of cnum to
uint32_t from a mix of int and unsigned.
