"Attempt to fix some build farm failures: On port 139 the first
successful packet gives len==0 from the server, so the = in
if (len <= 0) {
in line 136 of clientgen.c throws a failure."
The irritating thing is that I already had it correct in
SAMBA_3_0_26 and forgot to merge the change across.
len == 0 is a valid return - I messed that up when
converting client_receive_smb() to return a length
rather than a BOOL.
Doh !

Jeremy, please fix this properly, I'm not merging this to 3_0_26 so that
you can filter it when you merge.

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.

1. Fix a crash bug which should have reared its ugly head ages ago, but for
some reason, remained dormant until recently. The bug pertained to
libsmbclient doing a structure assignment of a cli after having opened a
pipe. The pipe open code makes a copy of the cli pointer that was passed
to it. If the cli is later copied (and that cli pointer that was saved
is no longer valid), the pipe code will cause a crash during shutdown or
when the copied cli is closed.
2. The 'type' field in enumerated shares was not being set correctly with
the new RPC-based mechanism for enumerating shares.

* 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 *.

supported pipe. Netlogon is still special, as we open that twice, one to do
the auth2, the other one with schannel.
The client interface is completely unchanged for those who only use a single
pie. cli->pipe_idx is used as the index for everything except the "real"
client rpc calls, which have been explicitly converted in my last commit. Next
step is to get winbind to just use a single smb connection for multiple pipes.

then is the client supports it (current clients supported are Samba and
CIFSVFS - detected by the negprot strings "Samba", "POSIX 2" and a bare
"NT LM 0.12" string) then the setting of the per packet flag smb_flag
FLAG_CASELESS_PATHNAMES is taken into account per packet. This allows
the linux CIFS client to use Samba in a case sensitive manner.
Additional command in smbclient "case_sensitive", toggles the
flag in subsequent packets.
Docs to follow.

We use cli_state.smb_rw_error to pass this specific case into cli_close_connection()
from smbmount as smb_rw_error can have only selected number of states and
it is ignored in cli_close_connection().
Compiled and tested by Lars Mueller from SuSE on x86, x86_64, ppc, ppc64, s390 and
s390x.

ago.
This patch re-adds support for 'optional' SMB signing. It also ensures that
we are much more careful about when we enable signing, particularly with
on-the-fly smb.conf reloads.
The client code will now attempt to use smb signing by default, and disable
it if the server doesn't correctly support it.

- NTLM2 support in the server
- KEY_EXCH support in the server
- variable length session keys.
In detail:
- NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).
* This is known as 'NTLMv2 session security' *
(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes. We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)
This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed. This also needs to be turned off for
'security=server', which does not support this.
- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.
- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.
- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation.
- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.
- The other big change is to allow variable length session keys. We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter. However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.
* This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *
- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe. This
should help reduce some of the 'it just doesn't work' issues.
- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer. (just allocate)
REMEMBER to make clean after this commit - I have changed plenty of data structures...
(This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)
Removed calls to clobber_region when not compiling with developer as
they were hiding speed problems.
Added fast path to convert_string() when dealing with ascii -> ascii,
ucs2-le to ascii and ascii to ucs2-le with values <= 0x7F. This
gives a speedup of 22% on my nbench tests.
Next I will do this on convert_string_allocate.

bug with w2k. Turns out that when we're doing a trans/trans2/nttrans call
the MID and send_sequence_number and reply_sequence_number must remain constant.
This was something we got very wrong in earlier versions of Samba. I can now
get a directory listing from WINNT\SYSTEM32 with the older earlier parameters
for clilist.c
This still needs to be fixed for the server side of Samba, client appears to
be working happily now (I'm doing a signed smbtar download of an entire W2K3
image to test this :-).
