Subject: [gentoo-dev] Handling /dev/rfkill, testers wanted
Date: Fri, 07 Mar 2014 19:20:53
Message-Id: 531A1B40.5020307@gentoo.org
1 - sys-apps/systemd has it's own service to handle /dev/rfkill from
2 99-systemd.rules we don't install with sys-fs/udev:
3
4 SUBSYSTEM=="rfkill", TAG+="systemd", IMPORT{builtin}="path_id",
5 ENV{SYSTEMD_WANTS}+="systemd-rfkill@$name.service"
6
7 - so this is about sys-fs/udev (and perhaps, sys-auth/consolekit for ACLs)
8 - since the udev .rules are not application specific, we should control
9 it from sys-fs/udev's /lib/udev/rules.d/40-gentoo.rules
10 - sys-fs/udev leaves it to root:root as:
11
12 KERNEL=="rfkill", MODE="0664"
13
14 - third party packages like mate-bluetooth, gnome-bluetooth install both
15 their own udev .rules to adjust /dev/rfkill to plugdev:
16
17 KERNEL=="rfkill", GROUP="plugdev", MODE="0664"
18
19 So I'd like to propose some unification:
20
21 I don't have a system with /dev/rfkill unfortunately to test this, but I
22 believe we should add this to 40-gentoo.rules and create group 'rfkill':
23
24 SUBSYSTEM=="rfkill", GROUP="rfkill", MODE="0664"
25
26 And this line would go as /lib/udev/rules.d/70-gentoo-acl.rules (as the
27 original filename in upstream ConsoleKit is 70-udev-acl.rules):
28
29 SUBSYSTEM=="rfkill", TAG+="udev-acl"
30
31 So that it would then look like:
32
33 $ ls -ld /dev/rfkill
34 crw-rw----+ 1 root rfkill 116, 1 Feb 21 16:27 /dev/rfkill
35
36 Notice the "+" there for ACLs if user is active (logged in using
37 ConsoleKit):
38
39 $ getfacl -a /dev/rfkill
40 # file: dev/rfkill
41 # owner: root
42 # group: rfkill
43 user::rw-
44 user:ssuominen:rw-
45 group::rw-
46 mask::rw-
47 other::---
48
49 I didn't actually run that just on /dev/rfkill, but I took an example
50 from /dev/snd/seq, and edited those at this mail.
51
52 I'd like someone with /dev/rfkill to test I'm right, if possible, and
53 verify no other cruft is interfering with it (like those of installed by
54 those apps I mentioned, `grep rfkill /lib/udev/rules.d/*`)
55
56 Any thoughts?
