talloc-allocated. Ideally, this memory should be talloc-stolen
(and perhaps have DATA_BLOB in the interface everywhere), but
that requires some more complex changes so I've just changed it to copy
it for now.
to specific bits every time a security descriptor is set. The S4 torture suite proves
that generic bits are not returned when querying an ACL set using them (ie. only
the specific bits are stored on disk).

This API is unusual in that if used to remove a non-list head it nulls out
the next and prev pointers. This is what you want for debugging (don't want
an entry removed from the list to be still virtually linked into it) but
means there is no consistent idiom for use as the next and prev pointers
get trashed on removal from the list, meaning you must save them yourself.
You can use it one way when deleting everything via the head pointer, as
this preserves the next pointer, but you *must* use it another way when not
deleting everything via the head pointer. Fix all known uses of this (the main
one is in conn_free_internal() and would not free all the private data entries
for vfs modules. The other changes in web/statuspage.c and winbindd_util.c
are not strictly neccessary, as the head pointer is being used, but I've done
them for consistency. Long term we must revisit this as this API is too hard
to use correctly.

This was my fault. I use a singleton cache (positive and negative) to speed up pathname based qfileinfo/setfileinfo lookups for alternate fsp's open on the same path. I only invalidated the negative cache on adding a new file fsp, as I incorrectly imagined the new fsp was put at the *end* of the open files list. DLIST_ADD puts it at the start, meaning any subsequent open wasn't seen once the cache was set. Doh !
Jeremy.
We don't need to deny a DELETE open on a readonly file (I'm also adding a s4
torture test for this), the set_file_disposition call will return
NT_STATUS_CANNOT_DELETE if the delete-on-close bit is set
on a readonly file (and we already do this).

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.

- only the first non truncating write causes
the write time update with 2 seconds delay.
It's not enough to check for an existing update event
as it will be NULL after the event was triggered.
- SMBwrite truncates always update the write time
unless the sticky write time is set.
- SMBwrite truncates don't trigger a write time update on close.

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.

The following test program prints "8" on 64-bit :-)
static void print_size(const char lenbuf[4])
{
printf("sizeof(lenbuf) = %d\n", (int)sizeof(lenbuf));
}
int main(void)
{
const char lenbuf[4];
print_size(lenbuf);
return 0;
}
Jeremy, please check :-)

We need to become root for AIO read and write to allow the AIO thread
to send a completion signal to the parent process when the IO
completes
(This used to be commit c548e5c69f)
Some of the bits generate INVALID_PARAMETER and some bits
are ignored when they come from a client, that's why we need
to use bits from the ignored range for our internal usage.

map_nt_error_from_unix() now assumes that it is called in
an error path and returns an error even for a given errno == 0.
The original behaviour of unix_convert() used the mapping
of errno == 0 ==> NT_STATUS_OK to return success through
an error path.
I think this must have been an oversight, and unix_convert() worked
only by coincidence (or because explicitly using the knowledge
of the conceptually wrong working of map_nt_error_from_unix().
This patch puts this straight by not interpreting errno == 0
as an error condition and proceeding in that case.
Jeremy - please check!
