Why? It moves these structs from the data into the text segment, so they
will never been copy-on-write copied. Not much, but as in German you say
"Kleinvieh macht auch Mist...."

the main server code paths. We should now be able to cope with
paths up to PATH_MAX length now.
Final job will be to add the TALLOC_CTX * parameter to
unix_convert to make it explicit (for Volker).
Jeremy.
(This used to be commit 7f0db75fb0)
This adds the two functions talloc_stackframe() and talloc_tos().
* When a new talloc stackframe is allocated with talloc_stackframe(), then
* the TALLOC_CTX returned with talloc_tos() is reset to that new
* frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
* happens: The previous talloc_tos() is restored.
*
* This API is designed to be robust in the sense that if someone forgets to
* TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
* resets the talloc_tos().
The original motivation for this patch was to get rid of the
sid_string_static & friends buffers. Explicitly passing talloc context
everywhere clutters code too much for my taste, so an implicit
talloc_tos() is introduced here. Many of these static buffers are
replaced by a single static pointer.
The intended use would thus be that low-level functions can rather
freely push stuff to talloc_tos, the upper layers clean up by freeing
the stackframe. The more of these stackframes are used and correctly
freed the more exact the memory cleanup happens.
This patch removes the main_loop_talloc_ctx, tmp_talloc_ctx and
lp_talloc_ctx (did I forget any?)
So, never do a
tmp_ctx = talloc_init("foo");
anymore, instead, use
tmp_ctx = talloc_stackframe()
:-)

that contains some of the fields from the SMB header, removing the need
to access inbuf directly. This right now is used only in the open file
code & friends, and creating that header is only done when needed. This
needs more work, but it is a start.
Jeremy, I'm only checking this into 3_0, please review before I merge it
to _26.
Volker
(This used to be commit ca988f4e79)
This replaces the internal explicit dev/ino file id representation by a
"struct file_id". This is necessary as cluster file systems and NFS
don't necessarily assign the same device number to the shared file
system. With this structure in place we can now easily add different
schemes to map a file to a unique 64-bit device node.
Jeremy, you might note that I did not change the external interface of
smb_share_modes.c.

(This used to be commit 9b10dbbd5d)
"file existed" case above. This has no functional
change but is easier to see that it's doing the
same thing.
Jeremy.
(This used to be commit 0a7d8362be)
file was being created and we go into the race condition check,
we were testing for compatible open modes, but were not breaking
oplocks in the same way as if the file existed. This meant that
we weren't going into the code path that sets fsp->oplock = FAKE_LEVEL_II_OPLOCK
if the client didn't ask for an oplock on file create. We need
to do this as internally it's what Windows does.
Jeremy.
(This used to be commit 9b9513856e)
Still missing lchown (will add this for 3.0.26).
Don't merge for 3.0.25a - possibly 3.0.25b (if it
exists).
Jeremy.
(This used to be commit f546750176)
This changes "struct process_id" to "struct server_id", keeping both is
just too much hassle. No functional change (I hope ;-))
Volker
(This used to be commit 0ad4b1226c)
Move more error code returns to NTSTATUS.
Client test code to follow... See if this
passes the build-farm before I add it into
3.0.25.
Jeremy.
(This used to be commit 83dbbdff34)
it needs the specific error message.
Make messages.c return NTSTATUS and specificially NT_STATUS_INVALID_HANDLE if
sending to a non-existent process.
Volker
(This used to be commit 3f620d181d)
void message_register(int msg_type,
void (*fn)(int msg_type, struct process_id pid,
- void *buf, size_t len))
+ void *buf, size_t len,
+ void *private_data),
+ void *private_data)
{
struct dispatch_fns *dfn;
So this adds a (so far unused) private pointer that is passed from
message_register to the message handler. A prerequisite to implement a tiny
samba4-API compatible wrapper around our messaging system. That itself is
necessary for the Samba4 notify system.
Yes, I know, I could import the whole Samba4 messaging system, but I want to
do it step by step and I think getting notify in is more important in this
step.

works - even with the strange "initial delete on close"
semantics. The "initial delete on close" flag isn't
committed to the share mode db until the handle is
closed, and is discarded if any real "delete on close"
was set. This allows me to remove the "initial_delete_on_close"
flag from the share db, and move it into a BOOL in files_struct.
Warning ! You must do a make clean after this. Cope with
the wrinkle in directory delete on close which is done
differently from files. We now pass all Samba4 smbtortute
BASE-DELETE tests except for the one checking that files
can't be created in a directory which has the delete on
close set (possibly expensive to fix).
Jeremy.
(This used to be commit f2df77a149)
Allow us to correctly refuse to set delete on close on a
non-empty directory. There are still some delete-on-close
wrinkles to be fixed, but I understand how to do that better
now. I'll fix this tomorrow.
Jeremy.
(This used to be commit 0296358858)
call_nt_transact_notify_change() is now sync if there are changes around.
A notify_message does a direct reply from within the message, so
process_pending_change_notify_queue is not needed anymore for samba-generated
events. Next step is to restructure the kernel-mechanisms to generate
messages.
Volker
(This used to be commit c813f71d00)
Checking in because Jeremy was bugging me. Potentially this becomes quite
intrusive, I'm not sure if I should open a temporary branch for this.
Jeremy, Jerry, do you think 3_0 is the right place for this?
Volker
(This used to be commit bcf5c751cb)
This involved passing the dirname as argument to a few routines instead of
calling parent_dirname() deep down.
Volker
(This used to be commit 7977fd7865)
error messages: We relied upon a stat that a directory did not exist to later
on then do the mkdir or not. This does the mkdir directly and copes with a
potential error.
The second one is more important: It's possible with Samba 3 to do a
ntcreate&x with NTCREATEX_OPTIONS_DIRECTORY and we happily do a NT_STATUS_OK.
Also move up the use_nt_status() logic a bit. I think this does not belong
into the core routines, the smb server as such should take care of it.
Jeremy, do you think this should go to 3.0.24?
I'll update samba4torture when the build farm has picked up this checkin.
Volker
(This used to be commit 472fb11f49)
on write-only files. Jim please check. Should not affect
Windows clients - I ensured all the relevent Samba4
torture tests still pass.
Jeremy.
(This used to be commit 6df3cac44f)
This has had some basic testing. I'll do more during the next couple of days and hopefully also
make RPC-SRVSVC from Samba4 pass against it.
