MS-CIFS section 2.2.7.4.2 states this is mandatory. WinXP clients
don't seem to care, but a Win7 client will send an immediate Close()
to the directory handle when receiving an incorrectly aligned
change notify response.
This shrinks include/includes.h.gch by the size of 7 MB and reduces build time
as follows:
ccache build w/o patch
real 4m21.529s
ccache build with patch
real 3m6.402s
pch build w/o patch
real 4m26.318s
pch build with patch

This patch introduces two new temporary helper functions
vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me
to call the new smb_filename version of stat, while avoiding plumbing
it through callers that are still too inconvenient. As the conversion
moves along, I will be able to remove callers of this, with the goal
being to remove all callers.
There was also a bug in create_synthetic_smb_fname_split (also a
temporary utility function) that caused it to incorrectly handle
filenames with ':'s in them when in posix mode. This is now fixed.
This optimizes non-recursive notifys. For non-recursive notifies we can use a
per-directory file-id indexed notify record. This matters for the Windows
Explorer and IIS cases which do not use recursive notifies. In these cases, we
do not have to shuffle around the whole notify record on every change.
For the cluster case, this improves correctness of the notifies, ctdb only
distributes the tdb seqnum once a second, so we can lose notifies.
* This allows a problem in the underlying CN backend to be bubbled up
to the general CN layer so a catch-all reply can be returned
* We now also return a catch-all response immediately if the server-side
event queue becomes too big
The OneFS kernel based change notify system takes an fd of the directory
to watch in it's initialization syscall. Since we already have this
directory open, this commit plumbs that fd down to the VFS layer via the
notify_entry struct.
We also need to know if the watch is taken out on a snapshot directory.
The full file_id struct is also passed down to make this determination.
The file_id marshalling wrappers are hand written here, but should
eventually be auto-generated by moving the struct file_id into the idl.
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 is necessary if we want to keep the whole smb_request for deferred ops.
The explicit settings of req->inbuf will be removed once all those deferring
operations are converted to store the whole request and not just the inbuf.
This patch is the first iteration of an inside-out conversion to cleanup
functions in charcnv.c returning size_t == -1 to indicate failure.

to zero). If non-zero, writeX calls greater than this
value will be left in the socket buffer for later handling
with recvfile (or userspace equivalent). Definition of
recvfile for your system is left as an exercise for
the reader (I'm working on getting splice working :-).

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()
