Will allow thread-specific credentials to be added by modifying
the central definitions. Deliberately left the setXX[ug]id()
call in popt as this is not used in Samba.
This hopefully fixes the build on systems where _LARGE_FILES
triggers defines of syscalls e.g. '#define lseek lseek64'
on AIX.

The problem occurs only if talloc, tdb and ldb are used as system
libraries and talloc is not installed in a default.

The new waf-based build system now has all the same functionality, and
the old build system has been broken for quite some time.

Only link to nss_wrapper when it is enabled.

This makes the structure much more like NT_USER_TOKEN in the source3/
code. (The remaining changes are that privilages still need to be merged)

This simply askes IDMAP about all the user SIDs, rather than the user
and group sid, followed by all but the first two sids from the token.

The includes of the UID wrapper headers werent't really efficient according
to metze's post on the technical mailing list (http://lists.samba.org/archive/samba-technical/2010-February/069165.html).
To achieve this move the "uid_wrapper.h" includes into "lib/util/unix_privs.c",
"lib/util/util.c", "ntvfs/posix/pvfs_acl.c" and "ntvfs/unixuid/vfs_unixuid.c".
This segfault occoured in cases where we rejected (or never attempted)
the tree connect, so had an invalid private pointer for the logoff
codepath.

This library intercepts seteuid and related calls, and simulates them
in a manner similar to the nss_wrapper and socket_wrapper
libraries. This allows us to enable the vfs_unixuid NTVFS module in
the build farm, which means we are more likely to catch errors in the
token manipulation.
The simulation is not complete, but it is enough for Samba4 for
now. The major areas of incompleteness are:
- no emulation of setreuid, setresuid or saved uids. These would be
needed for use in Samba3
- no emulation of ruid changing. That would also be needed for Samba3
- no attempt to emulate file ownership changing, so code that (for
example) tests whether st.st_uid matches geteuid() needs special
handling
This change brings ntvfs_connect into compliance with other ntvfs functions
which take an ntvfs module, an ntvfs request and an smb io union.
It now becomes the responsibility of ntvfs modules to examine
tcon->generic.level themselves and derive the share name and any other
options
directly; e.g.
const char *sharename;
switch (tcon->generic.level) {
case RAW_TCON_TCON:
sharename = tcon->tcon.in.service;
break;
case RAW_TCON_TCONX:
sharename = tcon->tconx.in.path;
break;
case RAW_TCON_SMB2:
default:
return NT_STATUS_INVALID_LEVEL;
}
if (strncmp(sharename, "\\\\", 2) == 0) {
char *p = strchr(sharename+2, '\\');
if (p) {
sharename = p + 1;
}
}
service.c smbsrv_tcon_backend() is called before ntvfs_connect and fills in
some of the tcon->..out values.
For the case of RAW_TCON_TCONX, it filles out tcon->tconx.out.tid and
tcon->tconx.out.options
For the case of RAW_TCON_TCON it fills out tcon->tcon.out.tid and
tcon->tcon.out.max_xmit
Thus the ntvfs_connect function for vfs modules may override these values
if desired, but are not required to.
ntvfs_connect functions are required to fill in the tcon->tconx.out.*_type
fields, for RAW_TCON_TCONX, perhaps something like:
if (tcon->generic.level == RAW_TCON_TCONX) {
tcon->tconx.out.fs_type = ntvfs->ctx->fs_type;
tcon->tconx.out.dev_type = ntvfs->ctx->dev_type;
}

(I fixed the ntvfs_connect() in the smb_server/smb2/
and the RAW_TCON_SMB2 switch case in the modules)

backend
The vfs_unixuid module changes the uid of the process when executing
operations on behalf of the user. Within the VFS backend we may rely
on semi-async calls, such as winbind calls, which will call the event
loop again. To cope with this we need to ensure that while inside
those calls we revert the uid to root, then revert back to the
connected user when we have finished with the semi-async calls.
