bug#38651: connman integration issue after recent updates

2019-12-17 Thread Reza Alizadeh Majd 
here is a sample configuration file that I used to reproduce the issue:

(use-modules (gnu)
 (gnu system nss)
 (gnu packages gnome)
 (gnu packages vim)
 (srfi srfi-1))

(use-service-modules desktop networking ssh xorg)
(use-package-modules screen ssh certs tls connman)

(operating-system
  (host-name "panther")
  (timezone "Asia/Tehran")
  (locale "en_US.utf8")

  ;; Boot in "legacy" BIOS mode
  (bootloader (bootloader-configuration
(bootloader grub-bootloader)
(target "/dev/sda")))
  (file-systems (cons (file-system
(device (file-system-label "my-root"))
(mount-point "/")
(type "ext4"))
  %base-file-systems))

  (users (cons (user-account
 (name "user")
 (comment "default user")
 (group "users")
 (supplementary-groups '("wheel" "audio" "video"))
 (home-directory "/home/user"))
%base-user-accounts))

  (packages (cons* openssh nss-certs gnutls cmst
   %base-packages))

  (services (cons* (service gnome-desktop-service-type)
   (service openssh-service-type
(openssh-configuration
  (port-number 22)
  (permit-root-login #t)
  (authorized-keys
`(("user" ,(local-file "/etc/vagrant.pub"))

   (service connman-service-type)
   (remove (lambda (service)

bug#38651: connman integration issue after recent updates

2019-12-17 Thread Reza Alizadeh Majd 
Hi Guix, 

I'm using `connman` + `cmst` for network management on my guix machine, 
recently after I updated the system, I receive following message after login 
and `cmst` can't communicate with `connman`. I also  tried with `econnman` 
interface and received same error: 

```
Error Name: org.freedesktop.DBus.Error.AccessDenied

Error Message: Rejected send message, 3 matched rules; type="method_call", 
sender=":1.108" (uid=1000 pid=3870 comm="cmst ") 
interface="net.connman.Manager" member="GetTechnologies" error name="(unset)" 
requested_reply="0" destination="net.connman" (uid=0 pid=369 
comm="/gnu/store/1ld7hpvnhcr5wjxd15bvgbwvd50j8i04-connma")
```

I also tried to modify `connman` package and add 



policy to connman debus config, based on suggested details in: 
https://forum.obarun.org/viewtopic.php?pid=3075#p3075

but the problem still occurs.
