the problem that stops libsmbclient being thread safe. Subsidiary
DFS connections are now hung off a list inside the cli_state struct.
Much more to do in order to get libsmbclient to thread safety, but
this is a good start.

Jeremy: requires your eyes...
If the remote connection timed out while cli_list() was retrieving its list of
files, the error was not returned to the user, e.g. via smbc_opendir(), so the
user didn't have a way to know to set the timeout longer and try again. This
problem would occur when a very large directory is being read with a too-small
timeout on the cli.
Jeremy, although there were a couple of areas that needed to be handled, I
needed to make one change that you should bless, in libsmb/clientgen.c. It
was setting
cli->smb_rw_error = smb_read_error;
but smb_read_error is zero, so this had no effect. I'm now doing
cli->smb_rw_error = READ_TIMEOUT;
instead, and according to the OP, these (cumulative) changes (in a slightly
different form) solve the problem.
Please confirm this smb_rw_error change will have no other adverse effects
that you can see.

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 :-).

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 :-).

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.

to buggy iconv?) we can
be left with a filename that doesn't exist on the remote machine. If we then do a findnext
with this file the server gets confused and restarts from the beginning of the directory,
causing directory listing loops. Fix this by keeping a copy of the "raw" filename data and
length and using this as the argument to findnext. This won't fix the incorrect iconv
conversion into the finfo struct but at least it ensures that directory listings always
terminate. Tested against NTFS and FAT directories.

* 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).
