The estimated EA size needs to be of the main file. However, the fsp
may point to the stream, so we need to ignore it if this is the case.
This may mean we estimate wrong if there has been a rename.
Andrew Bartlett
This ensures that we return the ea size of the stream, not the overall file.
This is important as if there is an EA on the main file, the raw.streams
test was failing.
Andrew Bartlett
It's not the client fault, if he doesn't know that encryption is required.
We should just return ACCESS_DENIED and let the client work on other
shares and open files on the current SMB connection.

We no longer do struct smb_acl_t manipuations via the VFS layer,
which is now reduced to handling the get/set functions.
The only backend that implemented these functions (aside from audit)
was the vfs_default module calling the sys_acl code. The various ACL
implementation modules either worked on the fully initilaised
smb_acl_t object or on NT ACLs.
This not only makes the operation of the posix ACL code more efficient
(as allocation and free is not put via the VFS), it makes it easier to
test and removes the fantasy that a module could safely redefine this
structure or the behaviour here.
The smb_acls.idl now defines the structure, and it is now allocated
with talloc.
These operations were originally added to the VFS in commit
3bb219161a.

This will allow us to remove the struct smb_acl_t manipuations from the VFS layer,
which will be reduced to handling the get/set functions.

As the test for a valid posix ACL is based on the unix uid/gid only appearing once in the ACL
the merge process also needs to be UID/GID based.
This is a problem when we have multiple builtin groups mapped to the same POSIX group
as happens in a Samba4 provision.

This is consistent with the rest of Samba which uses this structure to represent
a unix uid or gid.
World values remain represented by the owner_type being WORLD_ACE in the containing
structure. A -1 value is filled in to the unixid.id in the same way the .world value
was initialised in the union.

When a user owns a file, but does not have specific permissions on that file, we need to
make up the user permissions. This change ensures that the first thing that we do
is to look up the SID, and confirm it is a user. Then, we avoid the getpwnam()
and directly create the token via the SID.

req->in.vector[0] is reserved for the transport and might be removed in future.
This is currently always { NULL, 0 }, as it's not used, by our
transport layer code. The SMB2 layer should never touch this!

A timed brlock with 2 locks comes in and the second one blocks,
file is closed. smbd_cancel_pending_lock_requests_by_fid sets
blr->fsp to NULL. reply_lockingX_error (called via
MSG_SMB_BLOCKING_LOCK_CANCEL) deferences blr->fsp because
blr->lock_num==1 (the second one blocked).
This patch fixes the bug by only undoing the locks if fsp!=NULL.
fsp==NULL is the close case where everything is undone anyway.

Look for Server.Session.SessionKeyState in [MS-SMB].
The first SMBtconX sets the state to available, which makes it possible
to protect the session key at that stage, if client and server
support TREE_CONNECT_ANDX_EXTENDED_SIGNATURE.

We already have a server address in sockaddr_storage format.
Also the name "client_socket" was very miss leading,
as it returns the local address of the socket.

Only Windows8 Beta uses this and it's broken, the client send wrong

The core smbd must have taken care of this. If we don't do this properly,
we have a race of the close(2) against a pwrite(2). We might end up
writing to the wrong file.

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 fstat call into the block which opens a file descriptor.
Remove the stat() call in the stat-open case. We already failed

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.
