This change brings ntvfs_connect into compliance with other ntvfs functions
which take an ntvfs module, an ntvfs request and an smb io union.
It now becomes the responsibility of ntvfs modules to examine
tcon->generic.level themselves and derive the share name and any other
options
directly; e.g.
const char *sharename;
switch (tcon->generic.level) {
case RAW_TCON_TCON:
sharename = tcon->tcon.in.service;
break;
case RAW_TCON_TCONX:
sharename = tcon->tconx.in.path;
break;
case RAW_TCON_SMB2:
default:
return NT_STATUS_INVALID_LEVEL;
}
if (strncmp(sharename, "\\\\", 2) == 0) {
char *p = strchr(sharename+2, '\\');
if (p) {
sharename = p + 1;
}
}
service.c smbsrv_tcon_backend() is called before ntvfs_connect and fills in
some of the tcon->..out values.
For the case of RAW_TCON_TCONX, it filles out tcon->tconx.out.tid and
tcon->tconx.out.options
For the case of RAW_TCON_TCON it fills out tcon->tcon.out.tid and
tcon->tcon.out.max_xmit
Thus the ntvfs_connect function for vfs modules may override these values
if desired, but are not required to.
ntvfs_connect functions are required to fill in the tcon->tconx.out.*_type
fields, for RAW_TCON_TCONX, perhaps something like:
if (tcon->generic.level == RAW_TCON_TCONX) {
tcon->tconx.out.fs_type = ntvfs->ctx->fs_type;
tcon->tconx.out.dev_type = ntvfs->ctx->dev_type;
}

(I fixed the ntvfs_connect() in the smb_server/smb2/
and the RAW_TCON_SMB2 switch case in the modules)

smbsrv_tcon_backend no longer creates the ntvfs_request wrapper,
so smbsrv_reply_tcon* can now do this and then invoke ntvfs_connect
in the typical manner using SMBSRV_SETUP_NTVFS_REQUEST and
SMBSRV_CALL_NTVFS_BACKEND
Previously smbsrv_tcon_backend has been responsible for instantiating
the ntvfs_module_context to service a tree-connect request, and
then create an ntvfs_request wrapper around the smbsrv_request
and pass this to ntvfs_connect for the newly created ntvfs.
These actions could not be invoked asynchronously.
This meant that any client requests made while instantiating the
ntvfs module, including any composite's used during authentication
(or related client connections for the case of proxy modules)
would block other ntvfs modules and requests in the current process as
they executed a nested event loop to await completion.

Note that we don't use any protocol specific values here.
For now only NTVFS_CLIENT_CAP_LEVEL_II_OPLOCKS is defined
others should be defined, when we find out that the ntvfs
layer needs to know about it.

There are still a few tidyups of old FSF addresses to come (in both s3
and s4). More commits soon.

- to use a struct ntvfs_handle instead of a uint16_t fnum.
(to make it independend from the frontend protocol)
- the allocation of handles now is provided by the frontend
(smbsrv_*) via callbacks and not by each backend module
- this also makes sure that file handles are only passed
to the ntvfs subsystem when the tcon and session matches,
so modules can rely on this and need to check this.
- this allows multiple modules in the ntvfs module chain
to allocate file handles. This can be used for virtual
files like "\\$Extend\\$Quota:$Q:$INDEX_ALLOCATION"...
- also this will make SMB2 with 128 bit file handles possible

with this it's now possible to write a
ntvfs_test programm like the vfstest in samba3
also smb2 support will be possible later

in other places...
