region between detecting a pending lock was needed
and when we added the blocking lock record. Make
sure that we hold the lock over all this period.
Removed the old code for doing blocking locks on
SMB requests that never block (the old SMBlock
and friends).
Discovered something interesting about the strange
NT_STATUS_FILE_LOCK_CONFLICT return. If we asked
for a lock with zero timeout, and we got an error
of NT_STATUS_FILE_LOCK_CONFLICT, treat it as though
it was a blocking lock with a timeout of 150 - 300ms.
This only happens when timeout is sent as zero and
can be seen quite clearly in ethereal. This is the
real replacement for old do_lock_spin() code.
Re-worked the blocking lock select timeout to correctly
use milliseconds instead of the old second level
resolution (far too coarse for this work).

test. Phew - that was painful :-). But what it means
is that we now implement lock cancels and I can add
lock cancels into POSIX lock handling which will fix
the fast/slow system call issue with cifsfs !

This allows a requestor to set FORCE_OPLOCK_BREAK_TO_NONE
to ensure we don't break to level 2. Fixed a couple
of resource leaks in error paths in open_file_ntcreatex.

mid replies on path based set-eof trans2 calls.
Needs modification for HEAD (as in head open_file_ntcreateX
properly returns NTSTATUS - I'll fix this tomorrow my
time). Secondly it still fails the Samba4 RAW-OPLOCK
smbtorture because of an interesting case. Our oplock
code always returns "break to level 2" if it can.
In this case (path-based set-eof or set-allocation size
on an exclusive oplocked file) W2K3 always sends a
break-to-none. We send the break to none (from level2)
after we've done the write for eof or allocation size.
I need to work out some way of telling our break code
to always break to none (might need to extend the message
field).

(Thanks a lot for all your hard work on this).
We were caching the results of *all* directory
scans, not just the results that match the
client wildcard. This actually made no sense,
as only matches on the client wildcard can be
returned to the client and so might need to
be searched for in the cache. This fixes the
directory cache to only cache entries that we
return to the client.

realloc can return NULL in one of two cases - (1) the realloc failed,
(2) realloc succeeded but the new size requested was zero, in which
case this is identical to a free() call.
The error paths dealing with these two cases should be different,
but mostly weren't. Secondly the standard idiom for dealing with
realloc when you know the new size is non-zero is the following :
tmp = realloc(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
However, there were *many* *many* places in Samba where we were
using the old (broken) idiom of :
p = realloc(p, size)
if (!p) {
return error;
}
which will leak the memory pointed to by p on realloc fail.
This commit (hopefully) fixes all these cases by moving to
a standard idiom of :
p = SMB_REALLOC(p, size)
if (!p) {
return error;
}
Where if the realloc returns null due to the realloc failing
or size == 0 we *guarentee* that the storage pointed to by p
has been freed. This allows me to remove a lot of code that
was dealing with the standard (more verbose) method that required
a tmp pointer. This is almost always what you want. When a
realloc fails you never usually want the old memory, you
want to free it and get into your error processing asap.
For the 11 remaining cases where we really do need to keep the
old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR,
which can be used as follows :
tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the
pointer p, even on size == 0 or realloc fail. All this is
done by a hidden extra argument to Realloc(), BOOL free_old_on_error
which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR
macros (and their array counterparts).
It remains to be seen what this will do to our Coverity bug count :-).

reasonable to ensure uniqueness.

as well as the filename). Needed for #3303. Some code written

to locking/locking.c. The smbstatus output is a bit of a mess
and needs overhauling...

of the Samba4 timezone handling code back into Samba3.
Gets rid of "kludge-gmt" and removes the effectiveness
of the parameter "time offset" (I can add this back
in very easily if needed) - it's no longer being
looked at. I'm hoping this will fix the problems people
have been having with DST transitions. I'll start comprehensive
testing tomorrow, but for now all modifications are done.
Splits time get/set functions into srv_XXX and cli_XXX
as they need to look at different timezone offsets.
Get rid of much of the "efficiency" cruft that was
added to Samba back in the day when the C library
timezone handling functions were slow.
