atomic on POSIX.
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.

the create disposition correctly.

guaranteed indication of creation of a new file.

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.

on *BSD we get the immutable flag via st_flags, we should use that if possible.

A few lines before we did check for x != NULL. I think this might
fix a potential remote crash.

structures are available
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.

smbd_smb2_request_check_tcon()
smbXsrv_tcon0 is the internal name for the (current) version0 of the
structure. Externally, only smbXsrv_tcon should be used.
|
|
smbXsrv_session0 is the internal name of (current) version 0 of
the structure. Externally, only smbXsrv_session should be used.

If the SMB_VFS_OPEN() function returns -1, EINTR -> NT_STATUS_RETRY,
then queue the open up to be completed when the async open completes.

Ensure it is initialized so we know what mid created this file.

This makes sure we generate unique persistent file ids,
which are stored in smbXsrv_open_global.tdb.

smbd_smb2_request_verify_creditcharge()
The client can send any credit charge value, it's ok to send more than needed.

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.

simpler
We just need a max_charge variable to make the algorithm independent
of multi_credit support.

A credit charge of 0 is really not a special case, it just means the same
as 1.

In future we'll have other transports like RDMA.
This makes NBT (tcp port 139) special instead of port 445.

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.

Otherwise we'll never consume sequence id '0'.

This should also fix the build on Tru64. Tru64 has a POSIX compliant statvfs()
function while most *BSD systems ignore POSIX.

All calls which take an file handle have the same,
so we should also log it, when we create a handle.

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.
