We need to revalidate the pathname once re-constructed from a root fsp.

These variables, of type struct auth_serversupplied_info were poorly
named when added into 2001, and in good consistant practice, this has
extended all over the codebase in the years since.
The structure is also not ideal for it's current purpose. Originally
intended to convey the results of the authentication modules, it
really describes all the essential attributes of a session. This
rename will reduce the volume of a future patch to replaced these with
a struct auth_session_info, with auth_serversupplied_info confined to
the lower levels of the auth subsystem, and then eliminated.
(The new structure will be the output of create_local_token(), and the
change in struct definition will ensure that this is always run, populating
local groups and privileges).

Makes SMB2Create call re-entrant internally.
Now this infrastructure is in place, oplocks will follow shortly.
Tested with Win7 client and with W2K8R2.

This will allow us to share logic much easier between SMB1 and SMB2
servers.

Rename functions to be internally consistent. Next step is
to cope queueing single (non-compounded) SMB2 requests to
put some code inside the stubs.

Ensure we don't use any of the create_options for Samba private
use. Add a new parameter to the VFS_CREATE call (private_flags)
which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS
and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code).
Rev. the VFS interface to version 28.

in the "user.DOSATTRIB" EA. From the docs:
In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to store
the create time for a file as well as the DOS attributes. This is done in a backwards compatible
way so files created by Samba 3.5.0 and above can still have the DOS attribute read from this
extended attribute by earlier versions of Samba, but they will not be able to read the create
time stored there. Storing the create time separately from the normal filesystem meta-data
allows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem.
Passes make test but will need more testing.

When racing to the open and loosing we may get a share_mode violation.
In this case handle the 1-second delay via a defferred open properly.
This requires us to retrieve the share_mode_lock before deferring
open so we don't dereference a NULL pointer assuming we already had
the lck because we were the first opener.

to the same file.
Two openers can stat a file at the same time, see that it doesn't exist,
and then both race to open it first. The loser will enter
onefs_open_file_ntcreate believing that the file doesnt exist, and thus
skip any current state lookups for that file. This includes setting
the file_id, and having a valid stat buffer.
Normally on first create the file_id will be set during the open, but
the second opener in this scenario may fail the open (oplock/share mode)
and file_id will not be set, nor will the stat buffer be valid.
In the error paths of this patch, we now double check that the file_id
and the stat buffer are valid before doing other operations.

I used the smb_filename struct everywhere that was feasible for the
first pass. There are still some places in this path that need to be
changed to use smb_filename, but this is a good start.
I also:
- Removed fname/path arguments from a few functions that weren't
really using them.
- Added a utility function for detecting whether an smb_filename is a
stream.
|

This is the first of a series of patches that change path based
operations to operate on a struct smb_filename instead of a char *.
This same concept already exists in source4.
My goals for this series of patches are to eventually:
1) Solve the stream vs. posix filename that contains a colon ambiguity
that currently exists.
2) Make unix_convert the only function that parses the stream name.
3) Clean up the unix_convert API.
4) Change all path based vfs operation to take a struct smb_filename.
5) Make is_ntfs_stream_name() a constant operation that can simply
check the state of struct smb_filename rather than re-parse the
filename.
6) Eliminate the need for split_ntfs_stream_name() to exist.
My strategy is to start from the inside at unix_convert() and work my
way out through the vfs layer, call by call. This first patch does
just that, by changing unix_convert and all of its callers to operate
on struct smb_filename. Since this is such a large change, I plan on
pushing the patches in phases, where each phase keeps full
compatibility and passes make test.
The API of unix_convert has been simplified from:
NTSTATUS unix_convert(TALLOC_CTX *ctx,
connection_struct *conn,
const char *orig_path,
bool allow_wcard_last_component,
char **pp_conv_path,
char **pp_saved_last_component,
SMB_STRUCT_STAT *pst)
to:
NTSTATUS unix_convert(TALLOC_CTX *ctx,
connection_struct *conn,
const char *orig_path,
struct smb_filename *smb_fname,
uint32_t ucf_flags)
Currently the smb_filename struct looks like:
struct smb_filename {
char *base_name;
char *stream_name;
char *original_lcomp;
SMB_STRUCT_STAT st;
};
One key point here is the decision to break up the base_name and
stream_name. I have introduced a helper function called
get_full_smb_filename() that takes an smb_filename struct and
allocates the full_name. I changed the callers of unix_convert() to
subsequently call get_full_smb_filename() for the time being, but I
plan to eventually eliminate get_full_smb_filename().

A few functions in oplocks_onefs.c need to be accessed from the onefs
vfs module. It would be ideal if oplocks were implemented at the vfs
layer, but since they aren't yet, a new header is added to
source3/include to make these functions available to the onefs vfs
module. oplocks_onefs.o doesn't need to be linked into the onefs vfs
module explicitly, since it is already linked into smbd by default.
