This fixes bug #6519.
|
|
|
|
this works around some terrible use of talloc in the libnet code
|
|
|
|
These changes follow from the discussions on samba-technical. The
changes are in several parts, and stem from the inherent ambiguity
that was in talloc_free() and talloc_steal() when the pointer that is
being changes has more than one parent, via references.
The changes are:
1) when you call talloc_free() on a pointer with more than one parent
the free will fail, and talloc will log an error to stderr like this:
ERROR: talloc_free with references at some/foo.c:123
reference at other/bar.c:201
reference at other/foobar.c:641
2) Similarly, when you call talloc_steal() on a pointer with more
than one parent, the steal will fail and talloc will log an error to
stderr like this:
ERROR: talloc_steal with references at some/foo.c:123
reference at other/bar.c:201
3) A new function talloc_reparent() has been added to change a parent
in a controlled fashion. You need to supply both the old parent and
the new parent. It handles the case whether either the old parent was
a normal parent or a reference
The use of stderr in the logging is ugly (and potentially dangerous),
and will be removed in a future patch. We'll need to add a debug
registration function to talloc.

A dcerpc request may have a reference from a still completing async
callback, but we now consider the request to be complete. We want to
lose the main parent, leaving just the reference, if any.
|
|
|
|
This is one of the few cases where we want the object to be owned by
both the python object and C code
|
|
|
|
The previous code caused memory leaks, and also caused situations
where talloc_free could be called on pointers with multiple parents
The new approach is to have two functions:
py_talloc_import : steals the pointer, so it becomes wholly owned by
the python object
py_talloc_reference: uses a reference, so it is owned by both python
and C
|
|
|
|
|
|
|
|
The previous use of talloc_steal could cause a steal of a pointer that
had references. This ensures that doesn't happen
|
|
The upcoming talloc_free/talloc_reference changes change talloc_free
to be a macro. These two bits of code relied on it being a function
pointer

consumed_ucs is the number of bytes
of the UCS2 path consumed not counting any
terminating null. We need to convert
back to unix charset and count again
to get the number of bytes consumed from
the incoming path.

Now that the sanity checks for mount.cifs default to matching the
behavior of /bin/mount, then there is virtually no need for umount.cifs.
The only exception is when someone enables the loose setuid behavior in
mount.cifs.
If an unprivileged user mounts a share that isn't in /etc/fstab, then
/bin/mount won't allow that user to unmount it. In that situation,
umount.cifs will be necessary to allow unmounting the share.

This reworks the notes file to be less stream-of-consciousness and more
task for porting, with a very particular focus on a potential port of
Samba4 to use MIT Kerberos.

It seems quite reasonable to allow modules to re-initialise the set of
cached DNs on the ldb context.

This job is not complete (the partition module remains a unfinished
task), but now we do use the private ldb headers much less.

The previous code only allowed an KRB5_NT_ENTERPRISE name (an e-mail
list user principal name) in an AS-REQ. Evidence from the wild
(Win2k8 reportadely) indicates that this is instead valid for all
types of requests.
While this is now handled in heimdal/kdc/misc.c, a flag is now defined
in Heimdal's hdb so that we can take over this handling in future (once we start
using a system Heimdal, and if we find out there is more to be done
here).

The function LDB_lookup_principal() has been eliminated, and it's
contents spread back to it's callers. Removing the abstraction makes
the code clearer.
Also ensure we never pass unescaped user input to a LDB search
function.

I some cases the pointer value of tevent_context is the same again,
if we do something like:
ev1 = tevent_context_init();
...
fde = tevent_add_fd(ev1, fd, TEVENT_FD_READ...);
...
talloc_free(ev1);
...
ev2 = tevent_context_init();
if (ev1 == ev2) {
/* this can happen! */
}
if (tevent_fd_get_flags(fde) == 0) {
/* this is always true */
}
But the "talloc_free(ev1)" will set fde->event_ctx to NULL
and tevent_fd_get_flags() will always return 0.

This test talks to a DC as a joined workstation member - in the same way
winbindd does, in particular the calls used in this test's query pattern
will all request for SEC_FLAG_MAXIMUM_ALLOWED access_mask
(which pretty much all of samba's client code does as well).
In fact this test verifies that winbind can correctly talk to a samba dc using
samr dcerpc calls.

Unlike torture_suite_add_machine_bdc_rpc_iface_tcase() which joins as a BDC
(ACB_SRVTRUST) this joins as a member workstation (ACB_WSTRUST).

/bin/mount strips off the ro/rw options after setting the MS_RDONLY
flag appropriately. Make mount.cifs do the same thing.

By adding a new common setup_logging_stdout() API, we no longer need to abuse the ABI compatability between the different setup_logging() calls in Samba3 and Samba4's DEBUG() subsystems.
The revert of 49a6d757b4d944cd22c91b2838beb83f04fbe1e9 works with this
to fix bug 6211.

The problem is that the enum was previously a 'rachet', that is, it
would only reset to a level higher than it was previouly set to.
Changing the order broke file-based logging for our production sites.
This reverts commit 49a6d757b4d944cd22c91b2838beb83f04fbe1e9.
