This is a follow up to 69d61453df6019caef4e7960fa78c6a3c51f3d2a to
adjust the API to allow the lower layers allocate memory. Now the
memory can explicitly be freed rather than relying on talloc_tos().

This commit is mostly to cope with the removal of SamOemHash (replaced
by arcfour_crypt()) and other collisions (such as changed function
arguments compared to Samba3).
We still provide creds_hash3 until Samba3 uses the credentials code in
netlogon server

sbuf as invalid (if not already read via stat()). Still trying
to find the build farm RAW-STREAM errors and it's happening
in a openX call....

We keep the seqnum/mid mapping in the smb_request structure.
This also moves one global variable into the
smbd_server_connection struct.

Was missing case of "If file exists open. If file doesn't exist error."
Damn damn damn. CIFSFS client will have to have fallback cases
for this error for a long time.

This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS,
BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically:
* I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to
*_default as the default implementations of the VFS ops.
* The blocking_lock_record (BLR) is now passed into the brl_lock_windows and
brl_cancel_windows paths. The Onefs implementation uses it - future
implementations may find it useful too.
* Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a
lock_struct and call either the Posix or Windows lock function. These happen
to be the same for the default implementation.
* Added helper functions: increment_current_lock_count() and
decrement_current_lock_count().
* Minor spelling correction in brl_timeout_fn: brl -> blr.
* Changed blocking_lock_cancel() to return the BLR that it has cancelled. This
allows us to assert its the lock that we wanted to cancel. If this assert ever
fires, this path will need to take in the BLR to cancel, rather than choosing
on its own.
* Adds a small helper function: find_blocking_lock_record_by_id(). Used by the
OneFS implementation, but could be useful for others.

search requests.
By default this VFS call is a NOOP, but the onefs vfs module takes advantage
of it to initialize direntry search caches at the beginning of each

This changelist allows for the addition of custom performance
monitoring modules through smb.conf. Entrypoints in the main message
processing code have been added to capture the command, subop, ioctl,
identity and message size statistics.
|

This allows module implementors to customize what allocation size is
returned to the client.

|
1) Add in smb_file_time struct to clarify code and make room for createtime.
2) Get and set create time from SMB messages.
3) Fixup existing VFS modules + examples Some OS'es allow for the
setting of the birthtime through kernel interfaces. This value is
generically used for Windows createtime, but is not settable in the
code today.

version.h changes rather frequently. Since it is included via includes.h,
this means each C file will be a cache miss. This applies to the following
situations:
* When building a new package with a new Samba version
* building in a git branch after calling mkversion.sh
after a new commit (i.e. virtually always)
This patch improves the situation in the following way:
* remove inlude "version.h" from includes.h
* Use samba_version_string() instead of SAMBA_VERSION_STRING
in files that use no other macro from version.h instead of
SAMBA_VERSION_STRING.
* explicitly include "version.h" in those files that use more
macros from "version.h" than just SAMBA_VERSION_STRING.

When there are enough streams on a file to fill up the max_data_count
when responding to a trans2 streaminfo, samba is returning
NT_STATUS_BUFFER_TOO_SMALL. Windows handles this by returning
NT_STATUS_BUFFER_OVERFLOW while still sending as much of the data that
it can fit into the buffer. When the windows client sees
BUFFER_OVERFLOW, it retries the streaminfo with a larger buffer (2x).
The windows client starts at 2K and will continue increasing the
buffer size by two until it reaches 64K. If the streams don't fit in
64K the windows client seems to give up.
This patch fixes marshall_stream_info to overfill the buffer by 1
stream so that send_trans2_replies can properly detect the overflow
and return the correct status.

This replaces the is_dos_path bool with a more future-proof argument.
The next step is to plumb INTERNAL_OPEN_ONLY through this flag instead
of overridding the oplock_request.

SMB_VFS_CREATE_FILE

Now unix paths can be differentiated from windows paths so the
underlying create_file implementations can convert paths correctly.

Modify all callers of create_file to go through SMB_VFS_CREATE_FILE

The Windows Explorer creates temporary streams and renames
them later via SFILEINFO_RENAME_INFO. The newname comes
in as ":Stream:$DATA".

This is the one where I found the problem that led to 3.2.5. So if there is one
checkin in the last year that I would like others to review and *understand*,
it is this one :-)

This fixes a potential crash bug, a client can make us read memory we
should not read. Luckily I got the disp checks right...

Instead, fix up the outbuf in send_xx_reply. In those routines, we know
what we are returning.

If total_data == 4 Windows doesn't care what values
are placed in that field, it just ignores them.
The System i QNTC IBM SMB client puts bad values here,
so ignore them.

with write time,
just return what the underlying filesystem says. Trying not to confuse UNIX apps any more than necessary.

When alignment was in place, we pretended to send more data/params according to
the param_offset/param_length and data_offset/data_length parameters than would
actually fit into the SMB according to the NBSS length field.

Ok, here's the fix for the write times breakage
with the new tests in S4 smbtorture.
The key is keeping in the share mode struct
the "old_file_time" as the real write time,
set by all the write and allocation calls,
and the "changed_write_time" as the "sticky"
write time - set by the SET_FILE_TIME calls.
We can set them independently (although I
kept the optimization of not setting the
"old_file_time" is a "changed_write_time"
was already set, as we'll never see it.
This allows us to update the write time
immediately on the SMBwrite truncate case,
SET_END_OF_FILE and SET_ALLOCATION_SIZE calls,
whilst still have the 2 second delay on the
"normal" SMBwrite, SMBwriteX calls.
I think in a subsequent patch I'd like to
change the name of these from "old_file_time"
to "write_time" and "changed_write_time" to
"sticky_write_time" to make this clearer.
I think I also fixed a bug in Metze's original
code in that once a write timestamp had been
set from a "normal" SMBwriteX call the fsp->update_write_time_triggered
variable was set and then never reset - thus
meaning the write timestamp would never get
updated again on subsequent SMBwriteX's.
The new code checks the update_write_time_event
event instead, and doesn't update is there's
an event already scheduled.
Metze especially, please check this over for
your understanding.
Jeremy.
