Invalid pointers were being dereferenced in lookup_sids causing

This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

It is not used anywhere else, so make it also static and remove
it from proto.h

This is very similar to be1dfff02d562e42a7847bd02fed8538630d3f41

This patch picks the alphabetically smallest one of the multi-value attribute
"uid". This fixes a regression against 3.0 and also becomes deterministic.

Should make Solaris 10 builds look cleaner.

This commit is mostly to cope with the removal of SamOemHash (replaced
by arcfour_crypt()) and other collisions (such as changed function
arguments compared to Samba3).
We still provide creds_hash3 until Samba3 uses the credentials code in
netlogon server

This removes calls to push_*_allocate() and pull_*_allocate(), as well
as convert_string_allocate, as they are not in the common API
To allow transition to a common charcnv in future, provide Samba4-like
strupper functions in source3/lib/charcnv.c
(the actual implementation remains distinct, but the API is now shared)

This removes one more caller to pull_utf8_allocate()

This patch makes sure the original and temporary TDBs are closed
_before_ the rename. Originally, the open TDB was renamed, and so
the name passdb.tdb.tmp stayed around in the db context. Hence
upon client connect, the smbd children died because reinit_after_fork()
calling tdb_reopen_all() would try to reopen passdb.tdb.tmp which
existed no longer...

3 but using a different hash calculation than 3.2.x passwd
databases (also version 3). Introduces a minor version
number.

correctly. For the clustering case.
Clustered setups should have only ever used
the unsigned version of TDB_DATA in the
first place so they can't be in this mess :-).
Just do the normal upgrade in the clustered case.

A client sent a SID with authority 0 and 0 sub-authorities. W2k3 replies with
NT_STATUS_INVALID_SID, even if other SIDs in the list are valid.
Thanks to Pavel <wylda@volny.cz> for the bug report!

correctly.
This is a really nasty one to fix as in order to successfully update the
passdb.tdb we must do the equivalent of a tdbbackup to move to the new hash
values before we do the upgrade.

we end up returning the null sid instead of falling back to the legacy
code. Next time through the code we'll hit the negative cache and do
the right thing, but we still fail the first time.
If we fail the winbind id to sid mapping, call the legacy version. This
catches the case where we don't have a negative cache entry for the mapping.
This is better than returning the NULL sid to the caller.

This is the same bug that was fixed in other places of the code a few times
already:
A C compiler ONLY does automatic type conversions during an assignment.
Passing down a pointer to type A to a function taking type B as an
argument does NOT do any automatic type conversions.
If required, I can dig up the relevant portions of the C standard.

Implements a custom backend for onefs that exclusively uses the wbclient
interface for all passdb calls.
It lacks some features of a standard passdb.
In particular it's a read only interface and doesn't implement privileges.

When enabled this reverts smbd to the legacy domain remapping behavior when
a user provides an untrusted domain
This partially reverts d8c54fdd
|

After a lot of testing against various Windows servers (W2K, W2K3, W2K8),
within an AD domain it seems that unknown domains will only be translated
to the local account domain, not the netbios name of the member server's
domain. This makes samba act more like Windows.

This upgrades the TDBSAM_VERSION to 4 and SAMU_BUFFER_V4.

This marshalling isn't specific to tdbsam and it's
