+@subsubheading Web Service Discovery Daemon
+
+Web Service Discovery Daemon implements the WSD protocoll.  It is a
+drop-in replacement for host discovery that lack support for the SMBv1
+protocol.
+
+@defvr{Scheme Variable} wsdd-service-type
+
+Service type for the Web Service Discoery host daemon.  The value for
+this service type is a @code{wsdd-configuration} record.  The details
+for the @code{wsdd-configuration} record type are given below.
+@end defvr
+
+@deftp{Data Type} wsdd-configuration This data type represents the
+configuration for the wsdd service.
+
+@table @asis
+
+@item @code{package} (default: @code{wsdd})
+The wsdd package to use.
+
+@item @code{ipv4only?} (default: @code{#f})
+Only listen to ipv4 addresses.
+
+@item @code{ipv6only} (default: @code{#f})
+Only listen to ipv6 addresses.  Please note: Activating both options is
+not possible, since there would be no ip versions to listen to.
+
+@item @code{chroot} (default: @code{#f})
+Chroot into a sperate directory to prevent access to other directories.
+This is to increase security in case there is a vulnerability in
+@command{wsdd}.
+
+@item @code{hoplimit} (default: @code{1})
+Limit to the level of hops for multicast packets.  The default is
+@var{1} which should prevent packets from leaving the local network.
+
+@item @code{interface} (default: @code{'()})
+Limit to the given list of interfaces to listen to.  By default wsdd
+will listen to all interfaces.  Except the loopback interface is never
+used.
+
+@item @code{uuid-device} (default: @code{#f})
+The WSD protocol requires a device to have a UUID.  Set this to manually
+assign the service a UUID.
+
+@item @code{domain} (default: @code{#f})
+Notify this host is a member of an Active Directory.
+
+@item @code{hostname} (default: @code{#f})
+Manually set the hostname rather than letting @command{wsdd} inherit
+this host's hostname.
+
+@item @code{preserve-case?} (default: @code{#f})
+By default @command{wsdd} will convert the hostname in workgroup to all
+uppercase.  The opposite is true for hostnames in domains.  Setting this
+parameter will preserve case.
+
+@item @code{workgroup} (default: @var{"WORKGROUP"})
+Change the name of the workgroup.  By default @command{wsdd} reports
+this host being member of a workgroup.

[bug#54561] [PATCH 0/4] Add service declarations for Samba

[Simon Streit]

Hello!

Please find attached several patches to add Samba and wsdd as service
declaration for Guix.  My Samba service declaration has been cut down in length
since I am preparing a serialiser, which has not been finalised yet.

But I'd rather still have these patch posted here to see it pushed eventually.
Or others can test it to see if there are any other improvements that should
be done and in case I've missed something.  Though the service definition is
rather simple for now.


Kind regards
Simon Streit (4):
  services: Add samba service.
  doc: Add "Samba" chapter.
  doc: Add documentation for WSDD service.
  services: Add wsdd service.

I'd like to propose to have avahi added to the input list in samba.  With it
Unix based clients will find Samba hosts in local networks.  SMBv1 host

I have a local service definition for samba i wanted to upstream
at some point. Your service looks better then mine though.

Is it a good idea to create all those directories with the default
umask? I always wanted to investigate which of those directories
contains sensitive data. I never got around to.

Another thing i wanted to investigate: can samba and friends be run
as non-root users? I think it would be a good idea to do that if
possible.

fyi: I currently use samba as an AD DC.

Maybe it is a good idea to provide the samba tool-set by default. You could
add the following to your samba-service-type:

(service-extension profile-service-type
                    (compose list samba-configuration-samba))

Some of the samba tools are broken though. I send a patch some time ago
which tries to address this issue. Maybe you want to take a look?

Is it necessary to put the configuration file there?
Can be we do something like (system* "/.../testparm" #$smb.conf), where
smb.conf is the generated configuration file?

FWIW, you can use 'mkdir-p/perms' to set the permission bits.
The (string-append ...) can be simplified to:

  (system* #$(file-append package "/bin/testparm" "--suppres-prompt
#$smb.conf).

Also, would it be a good idea to use (invoke ...) instead of system, to
make sure errors are detected?  What is the 'suppress-prompt' for?

Greetings,
Maxime.

I don't see any configuration option after enable-winbindd?.  Also,
what does ‘manually enable’ mean here?  How can I determine if this
needs to be done?  Can it be done automatically instead of manually?

Maxime.

No, not really.  The Samba suit has a lot of tools that may want to look
into the default config directory.  It seems that any relevant
configuration belonging to Samba lands in smb.conf, that is looked into
anytime when needed.  That is my impression, and thus
placed it there.

I'm not so sure myself.  That was the end result of what had to be
created to have the service successfully initiate itself.  True that I
have not investigated this myself yet.  While writing this service I was
comparing the directory structure with Debian and Arch Linux, to be sure
that it would work.

My understanding now would be better to write invoke.  Thanks for
pointing this out.

Thanks.  It still counts as my first try writing a service.

Impressive!  It might be quite interesting to see how you managed to set
up an AD DC.  I stopped after certain tools began to crash.  I tried to
solve them here [1].  I just noticed that you had pushed some patches
some time ago too [2].  They're both addressing the same issues.  In
this case your patches are looking better than mine.

That means these tools are working for you now?

Oh, it looks like I was to quick at trimming my service definition
here.  There where config options that where removed, and had simply
removed the entries in the documentation too without rephrasing the
manual properly.  I should modify that patch then.

I mostly followed the step by step guide in the samba wiki [0]. I use this
AD DC mostly for testing and developing (kerberos, ldap). While following
the step by step guide i found that samba-tool and friends are not working,
so i tried to fix them, and yes, they do work for me currently using my patch.

My main motivation for running samba as AD DC is that i want to port sssd to
guix. Currently i have a hack for glibc which solves the libnss module lookup
issue. But all this needs more polish and time....

[bug#54561] v2 [PATCH 0/5] Add service declarations for Samba

[Simon Streit]

Please find attached an updated patch series.

I've made slight changes as follows:

 * The reference to further config options in the manual have been removed.
 * Samba's (samba-activation config) procedure has been slightly modified,
 * better cleaned up, regarding the mkdirs.  I've done more testing and it
 * appears that samba will only run when /var/{lib,log,run}/samba exist,
   including /var/lib/samba/private.  In this case it is chmod now to o700 to
   be on the save side.  Debian's directory structure is world readable though.
   In Arch it is o700.  If anyone objects, please make it world readable.  It
   appears that Samba lives and breathes in these directories, so they better
   be put there. 
 * Regarding smb.conf -- while this service technically doesn't need it placed
   at /etc/samba -- is convenient to have it placed there for other tools part
   of the Samba family to read it, and so that others can quickly look into its
   configuration.  I'll leave this for further debate whether it can stay there
   or not.
 * The packages samba and wsdd are included in profile-service-type so that they
   are generally available in the system profile.

I hope I didn't miss anything out.

+
+Web Service Discovery Daemon implements the WSD protocoll.  It is a
+drop-in replacement for host discovery that lack support for the SMBv1
+protocol.
+
+@defvr{Scheme Variable} wsdd-service-type
+

+@deftp{Data Type} wsdd-configuration This data type represents the

+
+@table @asis
+
+@item @code{package} (default: @code{wsdd})
+The wsdd package to use.
+
+@item @code{ipv4only?} (default: @code{#f})
+Only listen to ipv4 addresses.
+
+@item @code{ipv6only} (default: @code{#f})
+Only listen to ipv6 addresses.  Please note: Activating both options is
+not possible, since there would be no ip versions to listen to.
+
+@item @code{chroot} (default: @code{#f})
+Chroot into a sperate directory to prevent access to other directories.
+This is to increase security in case there is a vulnerability in
+@command{wsdd}.
+
+@item @code{hoplimit} (default: @code{1})
+Limit to the level of hops for multicast packets.  The default is
+@var{1} which should prevent packets from leaving the local network.
+
+@item @code{interface} (default: @code{'()})
+Limit to the given list of interfaces to listen to.  By default wsdd
+will listen to all interfaces.  Except the loopback interface is never
+used.
+
+@item @code{uuid-device} (default: @code{#f})
+The WSD protocol requires a device to have a UUID.  Set this to manually
+assign the service a UUID.
+
+@item @code{domain} (default: @code{#f})
+Notify this host is a member of an Active Directory.
+
+@item @code{hostname} (default: @code{#f})
+Manually set the hostname rather than letting @command{wsdd} inherit
+this host's hostname.
+
+@item @code{preserve-case?} (default: @code{#f})
+By default @command{wsdd} will convert the hostname in workgroup to all
+uppercase.  The opposite is true for hostnames in domains.  Setting this
+parameter will preserve case.
+
+@item @code{workgroup} (default: @var{"WORKGROUP"})
+Change the name of the workgroup.  By default @command{wsdd} reports
+this host being member of a workgroup.

[bug#54561] [PATCH 0/4] Add service declarations for Samba

[Ludovic Courtès]

Hi Simon,

Simon Streit <simon@netpanic.org> skribis:

> Please find attached an updated patch series.

It’s a huge amount of work that you did, and that’ll certainly be useful
to many!

> I've made slight changes as follows:
>
>  * The reference to further config options in the manual have been removed.
>  * Samba's (samba-activation config) procedure has been slightly modified,
>  * better cleaned up, regarding the mkdirs.  I've done more testing and it
>  * appears that samba will only run when /var/{lib,log,run}/samba exist,
>    including /var/lib/samba/private.  In this case it is chmod now to o700 to
>    be on the save side.  Debian's directory structure is world readable though.
>    In Arch it is o700.  If anyone objects, please make it world readable.  It
>    appears that Samba lives and breathes in these directories, so they better
>    be put there. 
>  * Regarding smb.conf -- while this service technically doesn't need it placed
>    at /etc/samba -- is convenient to have it placed there for other tools part
>    of the Samba family to read it, and so that others can quickly look into its
>    configuration.  I'll leave this for further debate whether it can stay there
>    or not.
>  * The packages samba and wsdd are included in profile-service-type so that they
>    are generally available in the system profile.

I didn’t look at everything in detail, but overall that LGTM.

There’s a couple of things that I think would be worth adjusting though:

>   services: Add samba service.
>   doc: Add "Samba" chapter.
>   doc: Add documentation for WSDD service.
>   services: Add wsdd service.
>   gnu: Add wsdd.

It seems patches are in the wrong order: I’d expect the wsdd package to
come before the wsdd service.

Regarding documentation: by convention, documentation for a service is
added in the same commit that adds the service, so that it’s
self-contained.  Could you squash them?

Last, it would be great if you could add a system test under
gnu/tests/samba.scm.  Essentially, that test would do what you probably
did manually already: spawning a VM running an OS with
‘samba-service-type’ and/or ‘wsdd-service-type’ and running an SMB
and/or WSD client to make sure the basics work.  You can get inspiration
from other system tests there, and see:

  https://guix.gnu.org/manual/devel/en/html_node/Running-the-Test-Suite.html

I have minor cosmetic comments that I’ll send separately.

Could you send a v3 addressing these issues?

Thanks!

Just write “New file.”, that’s enough.

Please also add it to gnu/local.mk and to po/guix/POTFILES.in.

Please add a ‘description’ field with Texinfo markup (it’s the
description you see when running ‘guix system search’.)

Remove colon after “services” (what follows is not a bullet list).

How about:

  @uref{https://www.samba.org, Samba} provides networks shares for
  folders and printers using the SMB/CIFS protocol commonly used on
  Windows.

What’s an “AD DC”?  In general please expand acronyms on their first
occurrence.

Lowercase.

Please use @defvr as is done elsewhere in the manual.

Samba is now added to the system profile, right?  Should this sentence
be removed?

That too would need a bit more context IMO.

Typo; but you can write “WSD” here, since that has been introduced
above.

“IPv6”, “IP”.

> +Chroot into a sperate directory to prevent access to other directories.

“separate”

s/hoplimit/hop-limit/ (two words), and in the code too.

Likewise, preferably ‘host-name’.

Just “New file.” and add it to gnu/local.mk.

Please use ‘match-record’ instead; it is less error-prone.

Please write full sentences in ‘description’, possibly with Texinfo

In what format does the DNS name need to be:

  * with trailing dot: foo.net.
  * without trailing dot: foo.net
  * non-punycoded: é.net
  * punycoded: <something with xn-...>
  * doesn't matter

[bug#54561] [PATCH v3 0/4] Add samba and wsdd to services list.

[simon]

From: Simon Streit <simon@netpanic.org>

Hello, here my third iteration preparing this patch series.

Now there are tests included too.  There is a slight modification in samba's
package declaration to include avahi as a dependency.  Samba uses avahi to
advertise instances to other hosts that understand mDNS through avahi.

Simon Streit (4):
  gnu: samba: Add avahi to inputs.
  services: Add samba service.
  gnu: Add wsdd.
  services: Add wsdd service.

+@subsubheading Web Service Discovery Daemon
+
+Web Service Discovery Daemon implements
+@uref{http://docs.oasis-open.org/ws-dd/discovery/1.1/os/wsdd-discovery-1.1-spec-os.html,
+Web Services Dynamic Discovery} protocol that enables host discovery --
+similar to Avahi -- over Multicast DNS.  It is a drop-in replacement for
+SMB hosts that have had SMBv1 disabled for security reasons.
+
+@defvr {Scheme Variable} wsdd-service-type
+
+Service type for the WSD host daemon.  The value for
+this service type is a @code{wsdd-configuration} record.  The details
+for the @code{wsdd-configuration} record type are given below.
+@end defvr
+
+@deftp{Data Type} wsdd-configuration This data type represents the
+configuration for the wsdd service.
+
+@table @asis
+
+@item @code{package} (default: @code{wsdd})
+The wsdd package to use.
+
+@item @code{ipv4only?} (default: @code{#f})
+Only listen to IPv4 addresses.
+
+@item @code{ipv6only} (default: @code{#f})
+Only listen to IPv6 addresses.  Please note: Activating both options is
+not possible, since there would be no IP versions to listen to.
+
+@item @code{chroot} (default: @code{#f})
+Chroot into a separate directory to prevent access to other directories.
+This is to increase security in case there is a vulnerability in
+@command{wsdd}.
+
+@item @code{hop-limit} (default: @code{1})
+Limit to the level of hops for multicast packets.  The default is
+@var{1} which should prevent packets from leaving the local network.
+
+@item @code{interface} (default: @code{'()})
+Limit to the given list of interfaces to listen to.  By default wsdd
+will listen to all interfaces.  Except the loopback interface is never
+used.
+
+@item @code{uuid-device} (default: @code{#f})
+The WSD protocol requires a device to have a UUID.  Set this to manually
+assign the service a UUID.
+
+@item @code{domain} (default: @code{#f})
+Notify this host is a member of an Active Directory.
+
+@item @code{host-name} (default: @code{#f})
+Manually set the hostname rather than letting @command{wsdd} inherit
+this host's hostname.  Only the host name part of a possible FQDN will
+be used in the default case.
+
+@item @code{preserve-case?} (default: @code{#f})
+By default @command{wsdd} will convert the hostname in workgroup to all
+uppercase.  The opposite is true for hostnames in domains.  Setting this
+parameter will preserve case.
+
+@item @code{workgroup} (default: @var{"WORKGROUP"})
+Change the name of the workgroup.  By default @command{wsdd} reports
+this host being member of a workgroup.

I had to revert the commit adding avahi to samba in commit
dc7191302e6d099a26673e08b78eb5f4b2a2b17b and added it to core-updates
as commit 4d0befe66ae7fa731b566090b471107bc4828018 instead, because it
caused too many rebuilds.
