676261fa08 selftest: replace global with explicit environment variables
This patch removes setting of NSS_WRAPPER and RESOLV_WRAPPER variables globally
in Samba3.pm (because setting them persistently/globally can create hidden
ordering dependencies). Instead, they are set on subprocesses as required, which
appears to be the following two places (aside from those places where they are
already set explicitly):
* calls to createuser in provision
* calls to wbinfo --ping-dc in wait_for_start

af005fcc84 selftest: apply NSS_WRAPPER_HOSTNAME to child processes
Currently, Samba3.pm returns a value for NSS_WRAPPER_HOSTNAME in provision, but
selftest.pl does not apply it, so Samba3.pm /also/ sets it in its own
environment. This breaks a command like this:

make test TESTS="samba3.blackbox.smbclient_ntlm.plain samba3.rpc.samba3.netlogon"

... since samba3.blackbox.smbclient_ntlm.plain runs in an nt4_member env,
thereby setting ENV{NSS_WRAPPER_HOSTNAME} to the value for a member, and
samba3.rpc.samba3.netlogon depended on NSS_WRAPPER_HOSTNAME as a username (until
previous commit).

7fa91fc479 smbd: Fix coredump on failing chdir during logoff
server_exit does an internal tree disconnect which requires a chdir to
the share directory. In case the file system encountered a problem and
the chdir call returns an error, this triggers a SERVER_EXIT_ABNORMAL
which in turn results in a panic and a coredump. As the log already
indicates the problem (chdir returned an error), avoid the
SERVER_EXIT_ABNORMAL in this case and not trigger a coredump.

f4d9b797e2 selftest: Fix upgradeprovision test by importing new objects for schema 45
The recent schema changes mean that the upgradeprovision test starts
failing. This is because it's using an old 4.0.0 schema (that doesn't
have these schema changes), but it's comparing it against a fresh
provision (which does have the changes). We can avoid this failure by
using the 'samba-tool domain schemaupgrade' to bring the old 4.0.0 schema
in line with a fresh provision. Note that the 'upgradeprovision --full'
test doesn't need this change as it seems to more aggressively copy over
any schema differences with a fresh provision.

d67f706b34 schema: Re-work extended rights handling in provision (prep for 2012R2)
Add the changes needed to provision a 2012 DC (mostly this just affects
the Extended Rights objects) by moving to the new extended-rights.ldif

The localizationDisplayId is not documented in MS-ATDS so these values
are moved to provision_configuation_modify.ldif and applied after the
display-specifiers.ldif

We don't enable the 2012R2 mode yet. The ${INC2012} variable
just gets replaced with '#' so the lines get commented out and not
applied.

This approach allows us to support provisioning both a 2008R2 DC or
a 2012R2 DC (so that we can test we can upgrade a 2008 DC to 2012).

7f62b16a12 vfs_nfs4acl_xattr: modernize ACL inheritance
This changes the way ACL inheritance is achieved in this
module.

Previously the module recursed to the next parent directory until the
share root was reached or a directory with an ACL xattr. If the share
root didn't contain an ACL xattr either a default ACL would be used.

This commit removed this recursive scanning and replaces it with the
same mechanism used by vfs_acl_xattr: by setting "inherit acls = yes"
just let smbd do the heavy lefting and inheritance.

For any file without ACL xattr we still synthesize a default ACL,
leveraging the existing default ACL function used by vfs_acl_xattr.

499fa6b4a6 selftest: Add test for initial link attribute RMD_VERSION value
While testing link conflicts I noticed that links on Windows start from
a different RMD_VERSION compared to Samba. This adds a simple test to
highlight the problem.

82b56e63b5 replmd: Handle single-valued conflicts for an existing link
Currently the code only handles the case where the received link
attribute is a new link (i.e. pdn == NULL). As well as this, we need to
handle the case where the conflicting link already exists, i.e. it's a
deleted link that has been re-added on another DC.

f196897bc8 replmd: Handle conflicts for single-valued link attributes better
If 2 DCs independently set a single-valued linked attribute to differing
values, Samba should be able to resolve this problem when replication
occurs.

If the received information is better, then we want to set the existing
link attribute in our DB as inactive.

If our own information is better, then we still want to add the received
link attribute, but mark it as inactive so that it doesn't clobber our
own link.

This still isn't a complete solution. When we add the received attribute
as inactive, we really should be incrementing the version, updating the
USN, etc. Also this only deals with the case where the received link is
completely new (i.e. a received link conflicting with an existing
inactive link isn't handled).
