The underlying problem
is that once SMBulogoff is called, all server_info contexts associated with the
vuid should become invalid, even if that's the context being currently used by
the connection struct (tid). When the SMBtdis comes in it doesn't need a valid
vuid value, but the code called inside vfs_full_audit always assumes that there
is one (and hence a valid conn->server_info pointer) available.
This is actually a bug inside the vfs_full_audit and other code inside Samba,
which should only indirect conn->server_info on calls which require AS_USER to
be set in our process table. I could fix all these issues, but there's no
guarentee that someone might not add more code that fails this assumption, as
it's a hard assumption to break (it's usually true).
So what I've done is to ensure that on SMBulogoff the previously used
conn->server_info struct is kept around to be used for print debugging purposes
(it won't be used to change to an invalid user context, as such calls need
AS_USER set). This isn't strictly correct, as there's no association with the
(now invalid) context being freed and the call that causes conn->server_info to
be indirected, but it's good enough for most cases.
The hard part was to ensure that once a valid context is used again (via new
sessionsetupX calls, or new calls on a still valid vuid on this tid) that we
don't leak memory by simply replacing the stored conn->server_info pointer. We
would never actually leak the memory (as all conn->server_info pointers are
talloc children of conn), but with the previous patch a malicious client could
cause many server_info structs to be talloced by the right combination of SMB
calls. This new patch introduces free_conn_server_info_if_unused(), which
protects against the above.

I don't think we should unconditionally send every refused connection attempt
to a share to syslog, that's where all debug level 0 messages end up.

We need to allow to set filesystem capabilities from the default vfs in
create_conn_struct() in order to find mixed-case filenames. Thanks Volker!
This one was hard to find, so a little longer explanation:
When a Windows client tries to upload e.g. the Xerox 4110 PS driver, the client
first uploads the driver files to the [print$] share. Some of them (in this case
the Windows Postscript drivers) are with uppercase filenames while some of them
(like the PPD file) are in lowercase. After the driver upload the client issues
the spoolss_AddPrinterDriverEx() call with level 6. There the client tries to
add the PPD file with an uppercase filename (while having stored it in lowercase
on the server). The internal spoolss add driver functions then could not find the
appropriate filename while trying to move them to the version subdirectory (in
this case W32X86/3) and fails then entire spoolss_AddPrinterDriverEx() call.
With this fix, the convert_unix_name() name finds the correct file and
the spoolss_AddPrinterDriverEx() succeeds.

Haven't checked this myself, but as I've already got several reports that Samba
won't compile against current OpenAFS anymore, I just believe Geza Gemes. This
patch only affects AFS code, so it should not hurt anything else.

That compiler does not like #if embedded into the macro NT_STATUS_IS_OK.

No idea why it works on my Linux without -lpthread ... :-)

It will be replaced by tdgram_context and tstream_context.

Tim, Steven, I haven't yet seen comments from you. You have been asking for
such a thing at SambaXP. Do you like this? :-)

Convert all uses of cli_open(), cli_nt_createXXX to NTSTATUS versions.
This is smaller than it looks, it just fixes a lot of old code.
Next up, ensure all cli_XX functions return NTSTATUS.

The objects for this module should probably be cleaned up once.

The merged version behaves differently: "Domain Users" is parsed into two
values, as it does not look at quotes. Samba3 users depend on the ability do
say for example
valid users = "domain users"
which would not work anymore with the merged version.
Thanks to Björn Jacke for testing this!

instead of reading the registry directly with tdb and activating the
configure options by hand.
This eliminates the need for repeating checks done in loadparm.
For instance it disables registry shares without path in the server
as is the case with text based shares.

A previous fix broke the invariant that *uid is always
initialized on return from create_token_from_username().
Restore it.
