on the wire. This allows us to go to nsec resolution
for systems that support it. It should also now be
easy to add a correct "create time" (birth time)
for systems that support it (*BSD). I'll be watching
the build farm closely after this one for breakage :-).

libreadline and those that don't. We always use the built-in readline
replacement for non-interactive mode. Interactive prompts are always
emitted to stdout and non-interactive mode never prompts at all.
Introduce x_fdup to avoid spuriously closing stdout when a logfile is
specified on the command line and setup_logging is called a second time.
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 :-).

lp_load() could not be called multiple times to modify parameter settings based
on reading from multiple configuration settings. Each time, it initialized all
of the settings back to their defaults before reading the specified
configuration file.
This patch adds a parameter to lp_load() specifying whether the settings should
be initialized. It does, however, still force the settings to be initialized
the first time, even if the request was to not initialize them. (Not doing so
could wreak havoc due to uninitialized values.)
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.

* BUG 2680: copy files from an MSDFS win2k root share
* BUG 2688: re-implement support for the -P (--port) option
* support connecting to an 'msdfs proxy' share on a Samba server
note that this does not handle the situation where the same \\server\share
is mounted mutliple times in the dfs tree since I store a single mount
path per struct cli_state *
* all the unix extension commands should work
* send the correct TRANS2_FINDFIRST format to 2k to
get a listing from a msdfs root share (tested against
smbd as well).
* mkdir, rmdir, etc... all seem ok.
I'm sure bugs will pop up so keep testing.
Last thing I plan on doing is to clean up the horrible
mess with connection management in smbclient and global
variables (so i can move the cli_cm_xx() routines to a
separate file).
cd up and down the tree and get directory listings.
Still have to figure out how to get a directory listing on a
2k dfs root. Also have to work out some issues with relative paths
that cross dfs mount points.
We're protected from the new code paths when connecting to
a non-dfs root share ( the flag from the tcon&X is stored
in the struct cli_state* )
and SMBsplclose commands (BUG 2010)
* clarify some debug messages in smbspool (also from Mike)
my changes:
* start adding msdfs client routines
* enable smbclient to maintain multiple connections
* set the CAP_DFS flag for our internal clienht routines.
I actualy have a dfs referral working in do_cd() but that code
is too ugly to live so I'm not checking it in just yet.
Further work is to merge with vl's changes in trunk to support multiple
TIDs per cli_state *.
Need to add printout functions in client and set posix acl in server.
SteveF - take a look at this for the cifsfs client !
Once this is working and tested the next step is to write this up for
the UNIX extensions spec. documents.
Jeremy.
