Ofer Tal <otsmb@shmoop.org> fully correctly noted that we're incrementing
num_validated_vuids twice per session setup, but decrement it only once.
Looking at sesssetup.c we always call register_initial_vuid() before
register_existing_vuid(), so there's no point in incrementing it in
register_existing_vuid().
Jeremy, please check!
str_list_make(). From Dan Sledz <dan.sledz@isilon.com>:
In samba 3.2 passing NULL or an empty string returned NULL.
In master, it now returns a list of length 1 with the first string set
to NULL (an empty list).
Jeremy.
Remove pstring from libsmb/clidfs.c except for a nasty
hack (that will be removed when pstrings are gone from
client/).

BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

vuid that was allocated whilst the connection is
being constructed and after the connection has been set up.
This is what Windows does and at least one client
(and HP printer) depends on this behaviour. As it
depends on the req struct not yet ported to SAMBA_3_2_0
(Volker, hint hint.... :-) I am not yet adding this
to that branch, but will investigate that tomorrow.

talloc_free()'ed at the end of a session.
Rework the passwd cache code to use talloc_unlink and
talloc_reference, to more carefully manage the cache.

fragmented into "max xmit" size security blob
chunks. Bug #4400. Needs limits adding, and also
a client-side version.

Vista sends the NTLMv2 blob by default in the tconX
packet. Make sure we save off the workgroup the user
was logged into on the client in the sessionsetupX
and re-use it for the NTLMv2 calc.

right now. r14112 broke it, in 3.0.22 register_vuid for security=share returns
UID_FIELD_INVALID which in current 3_0 is turned into an error condition. This
makes sure that we only call register_vuid if sec!=share and meanwhile also
fixes a little memleak.
Then I also found a crash in smbclient with sec=share and hostmsdfs=yes.
There's another crash with sec=share when coming from w2k3, but I need sleep
now.
Someone (jerry,jra?) please review the sesssetup.c change.
Thanks,

fail and we would still return success in the SMBsesssetup reply :-(
* Make sure to create the local token for the server_fino struct
in reply_spnego_kerberos() so that register_vuid() does not fail.
(how did this ever work?)
(This used to be commit 8dafa45b97020d1aceb027a85e18401c965bf402)
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 :-).
