- there is no alter_nak or alter_ack packet, its all done in an
alter_response
- auto-allocated the contex_ids
- tried to fix up the dcom code to work again with
alter_context. Jelmer, please take a look :)
dcerpc_alter_context and multiple context_ids in the dcerpc client
library.
This stage does the following:
- split "struct dcerpc_pipe" into two parts, the main part being "struct dcerpc_connection", which
contains all the parts not dependent on the context, and "struct dcerpc_pipe" which has
the context dependent part. This is similar to the layering in libcli_*() for SMB
- disable the current dcerpc_alter code. I've used a #warning until i
get the 2nd phase finished. I don't know how portable #warning is, but
it won't be long before I add full alter context support anyway, so it won't last long
- cleanup the allocation of dcerpc_pipe structures. The previous code
was quite awkward.
- added #if TALLOC_DEPRECATED around the _p functions
- fixes the code that broke from the above
while doing this I fixed quite a number of places that were
incorrectly using the non type-safe talloc functions to use the type
safe ones. Some were even doing multiplies for array allocation, which
is potentially unsafe.
- cleaned up some talloc usage in various files
I'd like to get to the point that we have no calls to talloc(), at
which point we will rename talloc_p() to talloc(), to encourage
everyone to use the typesafe functions.
related to filesharing. For example, in order to manipulate ACLs
properly its important to be able to call LookupSids, and to be able
to lookup what privileges a SID has.
- added 3 new commands to smbclient "lookupname", "lookupsid" and
"privileges"
Break out the samsync tests from RPC-NETLOGON into a new RPC-SAMSYNC,
that will cross-verify all the values.
Add support for the way netlogon credentials are shared between the
pipe that sets up schannel and the pipe that is encrypted with it.
Test this support, by calling both NETLOGON and SAMR operations in the
RPC-SCHANNEL test.
Move some of the Netlogon NEG flags into the .idl, now we have an idea
what a few of them really are.
Rename the sam_pwd_hash into a name that has meaning (all other crypto
functions were renamed in Samba4 ages ago).
Break out NTLMv2 functionality for operation on the NT hash - I intend
to do NTLMv2 logins in the samsync test in future, and naturally I
only have the hash.

I decided to use IDL/NDR to encode the attribute, as it gives us a
simple way to describe and extend the saved attributes.
The xattr code needs to hook into quite a few more places in the pvfs
code, but this at least gets the basics done. I will start encoding
alternate data streams streams, DOS EAs etc soon using the same basic
mechanism.
I'll probably stick to "version 1" for the xattr.idl for quite a while
even though it will be changing, as I don't expect anyone to be
deploying this in production just yet. Once we have production users
we will need to keep compatibility by supporting all the old version
numbers in xattr.idl.
- tidied up some of the system includes
- moved a few more structures back from misc.idl to netlogon.idl and samr.idl now that pidl
knows about inter-IDL dependencies
rather than doing everything itself. This greatly simplifies the
code, although I really don't like the socket_recv() interface (it
always allocates memory for you, which means an extra memcpy in this
code)
- fixed several bugs in the socket_ipv4.c code, in particular client
side code used a non-blocking connect but didn't handle EINPROGRESS,
so it had no chance of working. Also fixed the error codes, using
map_nt_error_from_unix()
- cleaned up and expanded map_nt_error_from_unix()
- changed interpret_addr2() to not take a mem_ctx. It makes absolutely
no sense to allocate a fixed size 4 byte structure like this. Dozens
of places in the code were also using interpret_addr2() incorrectly
(precisely because the allocation made no sense)
The motivation for this change was to avoid having to convert to/from
ucs2 strings for so many operations. Doing that was slow, used many
static buffers, and was also incorrect as it didn't cope properly with
unicode codepoints above 65536 (which could not be represented
correctly as smb_ucs2_t chars)
The two core functions that allowed this change are next_codepoint()
and push_codepoint(). These functions allow you to correctly walk a
arbitrary multi-byte string a character at a time without converting
the whole string to ucs2.
While doing this cleanup I also fixed several ucs2 string handling
bugs. See the commit for details.
The following code (which counts the number of occuraces of 'c' in a
string) shows how to use the new interface:
size_t count_chars(const char *s, char c)
{
size_t count = 0;
while (*s) {
size_t size;
codepoint_t c2 = next_codepoint(s, &size);
if (c2 == c) count++;
s += size;
}
return count;
}
taking a context (so when you pass a NULL pointer you end up with
memory in a top level context). Fixed it by changing the API to take a
context. The context is only used if the pointer you are reallocing is
NULL.
The intial motivation for this commit was to merge in some of the
bugfixes present in Samba3's chrcnv and string handling code into
Samba4. However, along the way I found a lot of unused functions, and
decided to do a bit more...
The strlen_m code now does not use a fixed buffer, but more work is
needed to finish off other functions in str_util.c. These fixed
length buffers hav caused very nasty, hard to chase down bugs at some
sites.
The strupper_m() function has a strupper_talloc() to replace it (we
need to go around and fix more uses, but it's a start). Use of these
new functions will avoid bugs where the upper or lowercase version of
a string is a different length.
I have removed the push_*_allocate functions, which are replaced by
calls to push_*_talloc. Likewise, pstring and other 'fixed length'
wrappers are removed, where possible.
I have removed the first ('base pointer') argument, used by push_ucs2,
as the Samba4 way of doing things ensures that this is always on an
even boundary anyway. (It was used in only one place, in any case).
