Because we should not call smbd_smb2_request_error() on an
request that is still running.
If the subreq implementes a cancel function, this should
take care of triggering smbd_smb2_request_error.

If we can find a valid session or tcon we'll set it after the lookup,
but it need to make sure to reset it if we don't find the session.
This fixes a problem where a compound unrelated request between
related requests doesn't reset the session.
If we have 3 requests in a compound chain, request 3 should never
use the id's cached from request 1. It should only every inherit
handles from request 2.

Sorry for the mistake, but the LastDir singleton cache in vfs_ChDir()
actually plays an important role. When we're processing a stream of
SMB1/SMB2/SMB3 requests we don't want to add a chdir()/getcwd()
system call pair on every request if they're all on the same connection
and dealing with the same base path.
I did some testing with a program that times 1,000,000 chdir()
requests vs. 1,000,000 strcmp requests and it's a penalty of 10x
doing the system calls.
Just because it's old code, doesn't mean it's bad :-(.

This will allow us to hash this, rather than the NT ACL it maps to.
This will in turn allow us to know if the NT ACL is valid even if we

We only grant durable handles for CIFS/SMB2 only access,
that means "kernel oplocks", "kernel share modes" and "posix locking"
need to be set to "no".
For now we also don't grant durable handles if delete on close
is active on the handle.

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,

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.

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].
