  [Impact]

   * It is a very bad user experience that the WiFi device is recognized
  as an Ethernet device making Ubuntu users unable to connect to WiFi
  network.

  [Test Case]

   * Find some laptop that can reduplicate this issue.
   * Keep rebooting the system until you see this issue.
   * Usually this issue can be reduplicated within 10 reboot cycles on the 
right laptop.

  [Regression Potential]

   * No trivial regression.

  [Original Bug Description]

  Forwarded https://bugzilla.gnome.org/show_bug.cgi?id=775613

  Version: NetworkManager 1.4.2

  This bug happens after power-on with probability about 1/50.
  That means we need to reboot about 50 times to get into the buggy situation.
  "nmcli d" shows the device type is ethernet:

  DEVICE   TYPE  STATECONNECTION
  wlp1s0   ethernet  unavailable  --
  lo   loopback  unmanaged--

  The bug starts from a race condition. But it is not the root cause.
  I've also attach 2 logs. One is in good situation. Another is in bad 
situation.
  This log is generated by applying a "log patch" to network-manager 1.4.2 so 
we can see more stuff.

  In the bad situation. The bug starts with race condition. But the race 
condition is not the root cause. The race condition is:
   * During the renaming from "wlan0" to "wlp1s0". "wlan0" disappeared.
   * Inside the NM, it is still using "wlan0" in "_linktype_get_type()".
   * Since /sys/class/net/wlan0/uevent is disappeared. so the type matching 
failed in _linktype_get_type().
   * Also wifi_utils_is_wifi() failed to because /sys/class/net/wlan0 
disappeared.
   * And finally, devtype and kind are both NULL, so it returns 
NM_LINK_TYPE_ETHERNET for wlan0.

  Later, wlan0 is renamed to wlp1s0, and it seems to me that the Object inherit 
the type so it is still type ethernet.
  But from the log, I saw _linktype_get_type() is called several times later 
and return the correct type (wifi). But just, "nmcli d" still shows type 
ethernet.

  I'm wondering if we are missing to update the type in the Object
  created after renaming and re-detecting the type.

  fix need landing LP: #1645698

# The following patches (backported from 1.4) are directly from

platform-refactor-nmp_utils_sysctl_open_netdir.patch
all-use-O_CLOEXEC-for-file-descriptors.patch

Some header files are changed such as src/nm-core-utils.h, 
src/platform/wifi/wifi-utils.h, shared/nm-utils/nm-macros-internal.h and 
src/platform/nm-platform-utils.h.
But only src/platform/wifi/wifi-utils.h changed the interface a little bit 
while other only added some new interfaces.

src/platform/wifi/wifi-utils.h's change is like the following.

# from platform-refactor-wifi_utils_is_wifi-not-to-pass-sys.patch
-gboolean wifi_utils_is_wifi (const char *iface, const char *sysfs_path);
+gboolean wifi_utils_is_wifi (const char *iface);

# from platform-wifi-use-nmp_utils_open_sysctl-to-check-if-.patch
-gboolean wifi_utils_is_wifi (const char *iface);
+gboolean wifi_utils_is_wifi (int ifindex, const char *ifname);

However these header files are just internal and they should not affect
outside.

   * During the renaming from "wlan0" to "wlp1s0". "wlan0" disappeared.
   * Inside the NM, it is still using "wlan0" in "_linktype_get_type()".
   * Since /sys/class/net/wlan0/uevent is disappeared. so the type matching 
failed in _linktype_get_type().
   * Also wifi_utils_is_wifi() failed to because /sys/class/net/wlan0 
disappeared.
   * And finally, devtype and kind are both NULL, so it returns 
NM_LINK_TYPE_ETHERNET for wlan0.

  Later, wlan0 is renamed to wlp1s0, and it seems to me that the Object inherit 
the type so it is still type ethernet.
  But from the log, I saw _linktype_get_type() is called several times later 
and return the correct type (wifi). But just, "nmcli d" still shows type 
ethernet.

  I'm wondering if we are missing to update the type in the Object
  created after renaming and re-detecting the type.

  Version: NetworkManager 1.4.2

  This bug happens after power-on with probability about 1/50.
  That means we need to reboot about 50 times to get into the buggy situation.
  "nmcli d" shows the device type is ethernet:

  DEVICE   TYPE  STATECONNECTION
  wlp1s0   ethernet  unavailable  --
  lo   loopback  unmanaged--

  The bug starts from a race condition. But it is not the root cause.
  I've also attach 2 logs. One is in good situation. Another is in bad 
situation.
  This log is generated by applying a "log patch" to network-manager 1.4.2 so 
we can see more stuff.

  In the bad situation. The bug starts with race condition. But the race 
condition is not the root cause. The race condition is:
   * During the renaming from "wlan0" to "wlp1s0". "wlan0" disappeared.
   * Inside the NM, it is still using "wlan0" in "_linktype_get_type()".
   * Since /sys/class/net/wlan0/uevent is disappeared. so the type matching

  Later, wlan0 is renamed to wlp1s0, and it seems to me that the Object inherit 
the type so it is still type ethernet.
  But from the log, I saw _linktype_get_type() is called several times later 
and return the correct type (wifi). But just, "nmcli d" still shows type 
ethernet.

  I'm wondering if we are missing to update the type in the Object
  created after renaming and re-detecting the type.

  Version: NetworkManager 1.4.2

  This bug happens after power-on with probability about 1/50.
  That means we need to reboot about 50 times to get into the buggy situation.
  "nmcli d" shows the device type is ethernet:

  DEVICE   TYPE  STATECONNECTION 
  wlp1s0   ethernet  unavailable  --
  lo   loopback  unmanaged-- 

  The bug starts from a race condition. But it is not the root cause.
  I've also attach 2 logs. One is in good situation. Another is in bad 
situation.
  This log is generated by applying a "log patch" to network-manager 1.4.2 so 
we can see more stuff.

  In the bad situation. The bug starts with race condition. But the race 
condition is not the root cause. The race condition is:
   * During the renaming from "wlan0" to "wlp1s0". "wlan0" disappeared.
   * Inside the NM, it is still using "wlan0" in "_linktype_get_type()".
   * Since /sys/class/net/wlan0/uevent is disappeared. so the type matching 
failed in _linktype_get_type().
   * Also wifi_utils_is_wifi() failed to because /sys/class/net/wlan0 
disappeared.
   * And finally, devtype and kind are both NULL, so it returns 
NM_LINK_TYPE_ETHERNET for wlan0.

  Later, wlan0 is renamed to wlp1s0, and it seems to me that the Object inherit 
the type so it is still type ethernet.
  But from the log, I saw _linktype_get_type() is called several times later 
and return the correct type (wifi). But just, "nmcli d" still shows type 
ethernet.

Hi chih, the patch can't apply cleanly in nm-1.2, needs some porting.

@Aron, may we know if the patch suggested in comment#2 already in the

  Version: NetworkManager 1.4.2

  This bug happens after power-on with probability about 1/50.
  That means we need to reboot about 50 times to get into the buggy situation.
  "nmcli d" shows the device type is ethernet:

  DEVICE   TYPE  STATECONNECTION 
  wlp1s0   ethernet  unavailable  --
  lo   loopback  unmanaged-- 

  The bug starts from a race condition. But it is not the root cause.
  I've also attach 2 logs. One is in good situation. Another is in bad 
situation.
  This log is generated by applying a "log patch" to network-manager 1.4.2 so 
we can see more stuff.

  In the bad situation. The bug starts with race condition. But the race 
condition is not the root cause. The race condition is:
   * During the renaming from "wlan0" to "wlp1s0". "wlan0" disappeared.
   * Inside the NM, it is still using "wlan0" in "_linktype_get_type()".
   * Since /sys/class/net/wlan0/uevent is disappeared. so the type matching 
failed in _linktype_get_type().
   * Also wifi_utils_is_wifi() failed to because /sys/class/net/wlan0 
disappeared.
   * And finally, devtype and kind are both NULL, so it returns 
NM_LINK_TYPE_ETHERNET for wlan0.

  Later, wlan0 is renamed to wlp1s0, and it seems to me that the Object inherit 
the type so it is still type ethernet.
  But from the log, I saw _linktype_get_type() is called several times later 
and return the correct type (wifi). But just, "nmcli d" still shows type 
ethernet.

  I'm wondering if we are missing to update the type in the Object
  created after renaming and re-detecting the type.
