            Bug ID: 86260
           Summary: systemd-rfkill does not consider hard blocking
           Product: systemd
           Version: unspecified
          Hardware: All
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: systemd-bugs at lists.freedesktop.org
          Reporter: pilo at ayeon.org
        QA Contact: systemd-bugs at lists.freedesktop.org

I have the following wlan adapter:
  03:00.0 Network controller [0280]: Intel Corporation Ultimate N WiFi Link
5300 [8086:4236]

The kernel locks this via rfkill on boot:
  iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

And rfkill lists the following:
  # rfkill list
  0: phy0:t Wireless LAN
          Soft blocked: no
          Hard blocked: yes
  ...  
  # pwd
  /sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.0/ieee80211/phy0/rfkill0
  # cat soft hard
  0
  1

Wireless does not work in this state.

To fix, I have to run "rfkill unblock wifi" or similar, manually. After
unblock, i get the following output:
  # rfkill list
  0: phy0:t Wireless LAN
          Soft blocked: no
          Hard blocked: no
  ...
  # pwd
  /sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.0/ieee80211/phy0/rfkill0
  # cat soft hard
  0
  0

According to the source in src/rfkill/rfkill.c only the state in the file
"soft" is saved and restored. But "hard" should also be handled.
