193bb824e2 s3:modules: Fix compilation of nfs41acl_xdr.c when building outside src
If the Samba build directory is outside its source directory, generation
of nfs41acl_xdr.c by rpcgen leads to improper include paths to nfs41acl.h.

This happens because rpcgen is designed to produce its generated file in the
same directory as the input template. If the build directory is not located
under the source directory, this relative path will be invalid and the header
will not be found.

Example:
 src dir is ~/samba-src
 bld dir is ~/samba-bld

rpcgen will use path ../../samba-src/source3/modules/nfs41acl.x
running from ~/samba-bld/default and nfs41acl_xdr.c will contain:
 #include "../../samba-src/source3/modules/nfs41acl.h"

This behaviour is fixed through an intermediate copy of the input file to
the build directory so that rpcgen receives the path as if located in src.

Also now we avoid generation of nfs41acl_xdr.c when HAVE_RPC_XDR_H is
not defined because it will not be used as part of the vfs_nfs4acl_xattr
module.

835e156494 dnsserver: Return access denied to the caller if the user was not a DNS admin
This is not a proper fix to match Windows, but at the very least, it
should be more obvious to users (using samba-tool for instance), that
the user needs to be given more access or that they should use the
administrator.

Windows seems to deny access altogether by returning a fault after they
have bound to the pipe and actually sent an operation.

Originally added for BUG: https://bugzilla.samba.org/show_bug.cgi?id=13584

3204dc66f6 s3: VFS: vfs_fruit. Fix the NetAtalk deny mode compatibility code.
This exhibited itself as a problem with OFD locks reported
as:

BUG: https://bugzilla.samba.org/show_bug.cgi?id=13770

However, due to underlying bugs in the vfs_fruit
code the file locks were not being properly applied.

There are two problems in fruit_check_access().

Problem #1:

Inside fruit_check_access() we have:

flags = fcntl(fsp->fh->fd, F_GETFL);
..
if (flags & (O_RDONLY|O_RDWR)) {

We shouldn't be calling fcntl(fsp->fh->fd, ..) directly.
fsp->fh->fd may be a made up number from an underlying
VFS module that has no meaning to a system call.

Secondly, in all POSIX systems - O_RDONLY is defined as
*zero*. O_RDWR = 2.

Which means flags & (O_RDONLY|O_RDWR) becomes (flags & 2),
not what we actually thought.

Problem #2:

deny_mode is *not* a bitmask, it's a set of discrete values.

Inside fruit_check_access() we have:

if (deny_mode & DENY_READ) and also (deny_mode & DENY_WRITE)

However, deny modes are defined as:

/* deny modes */
define DENY_DOS 0
define DENY_ALL 1
define DENY_WRITE 2
define DENY_READ 3
define DENY_NONE 4
define DENY_FCB 7

so if deny_mode = DENY_WRITE, or if deny_mode = DENY_READ
then it's going to trigger both the if (deny_mode & DENY_READ)
*and* the (deny_mode & DENY_WRITE) conditions.

These problems allowed the original test test_netatalk_lock code to
pass (which was added for BUG: https://bugzilla.samba.org/show_bug.cgi?id=13584
to demonstrate the lock order violation).

This patch refactors the fruit_check_access()
code to be much simpler (IMHO) to understand.

Firstly, pass in the SMB1/2 share mode, not old
DOS deny modes.

Secondly, read all the possible NetAtalk locks
into local variables:

netatalk_already_open_for_reading
netatalk_already_open_with_deny_read
netatalk_already_open_for_writing
netatalk_already_open_with_deny_write

Then do the share mode/access mode checks
with the requested values against any stored
netatalk modes/access modes.

Finally add in NetATalk compatible locks
that represent our share modes/access modes
into the file, with an early return if we don't
have FILE_READ_DATA (in which case we can't
write locks anyway).

The patch is easier to understand by looking
at the completed patched fruit_check_access()
function, rather than trying to look at the
diff.

96cdacae14 s3/libsmb/py: match input argument types with C types
If PyArg_ParseTupleAndKeywords() is given, say, an "H" format (meaning
unsigned short int) but the referenced variable is a plain unsigned
int, the top 16 bits of the variable will be left undefined. In that
case we should use an "I" format (and/or initialize the variable).

In many cases the change is fairly innocuous, such as when "i" and "I"
are mixed (for signed and unsigned ints respectively), but the
resulting write is the same size and probably gives the same result in
practice.

87149445af s4/scripting/bin: open unicode files with utf8 encoding and write unicode string
In files like `libcli/util/werror_err_table.txt` and `libcli/util/ntstatus_err_table.txt`,
there were unicode quote symbols at line 6:

    ...(“this documentation”)...

In `libcli/util/wscript_build`, it will run `gen_werror.py` and `gen_ntstatus.py`
to `open` above files, read content from them and write to other files.

When encoding not specified, `open` in both python 2/3 will guess encoding from locale.

When locale is not set, it defaults to POSIX or C, and then python will use
encoding `ANSI_X3.4-1968`.

So, on a system locale is not set, `make` will fail with encoding error
for both python 2 and 3:

    File "/home/ubuntu/samba/source4/scripting/bin/gen_werror.py", line 139, in main
        errors = parseErrorDescriptions(input_file, True, transformErrorName)
      File "/home/ubuntu/samba/source4/scripting/bin/gen_error_common.py", line 52, in parseErrorDescriptions
        for line in file_contents:
      File "/usr/lib/python3.5/encodings/ascii.py", line 26, in decode
        return codecs.ascii_decode(input, self.errors)[0]
    UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 318: ordinal not in range(128)

In this case, we have to use `io.open` with `encoding='utf8'`.
However, then we got unicode strs and try to write them with other strs
into new file, which means the new file must also open with utf-8 and
all other strs have to be unicode, too.

Instead of prefix `u` to all strs, a more easier/elegant way is to enable
unicode literals for the python scripts, which we normally didn't do in samba.

Since both `gen_werror.py` and `gen_ntstatus.py` are bin scripts and no
other modules import them, it should be ok for this case.

e29c34942d decref results of PyStr_FromString
Where we create temporary objects (which are added to containers)
these objects already get there ref count incremented. In this case
we need to decref those objects to ensure they are released.

a8e10a1249 Decrement references to python objects passed to Py_BuildValue
Py_BuildValue when processing format 'O' will
  'Pass a Python object untouched (except for its reference count,
   which is incremented by one'

Basically this means if you are using a new reference to a PyObject
to pass to BuildValue (to be used with the 'O' format) the reference
*isn't* stolen so you really do need to DECREF it in order to ensure
it gets cleaned up.

95b2c9d775 autobuild: Split backup/restore testenvs out into separate job
The samba-ad-dc-2 job was reaching its limits with the number of
testenvs and what the resource-limited CI machines can handle.
Samba processes were getting swapped out of memory, causing CI runs
to fail.

This patch splits the backup/restore testenv targets into a separate
autobuild job: samba-ad-dc-backup.
