[ Upstream commit ddea788c63094f7c483783265563dd5b50052e28 ]

After Commit 8a8efa22f51b ("bonding: sync netpoll code with bridge"), it
would set slave_dev npinfo in slave_enable_netpoll when enslaving a dev
if bond->dev->npinfo was set.

However now slave_dev npinfo is set with bond->dev->npinfo before calling
slave_enable_netpoll. With slave_dev npinfo set, __netpoll_setup called
in slave_enable_netpoll will not call slave dev's .ndo_netpoll_setup().
It causes that the lower dev of this slave dev can't set its npinfo.

One way to reproduce it:

  # modprobe bonding
  # brctl addbr br0
  # brctl addif br0 eth1
  # ifconfig bond0 192.168.122.1/24 up
  # ifenslave bond0 eth2
  # systemctl restart netconsole
  # ifenslave bond0 br0
  # ifconfig eth2 down
  # systemctl restart netconsole

The netpoll won't really work.

This patch is to remove that slave_dev npinfo setting in bond_enslave().

Revert "ath10k: send (re)assoc peer command when NSS changed" 2018-04-29T09:31:58+00:00 Karthikeyan Periyasamy periyasa@codeaurora.org 2018-03-27T08:25:29+00:00 237b5a362399bdd81422ef9f9ac9b9f034161efd commit 55cc11da69895a680940c1733caabc37be685f5e upstream. This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159. When Ath10k is in AP mode and an unassociated STA sends a VHT action frame (Operating Mode Notification for the NSS change) periodically to AP this causes ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during NSS update. Over the time (with a certain client it can happen within 15 mins when there are over 500 of these VHT action frames) continuous calls of WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust. To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS updates and no need to call ath10k_station_assoc(). So revert the original commit from 2014 as it's unclear why the change was really needed. Now the firmware assert doesn't happen anymore.

commit 55cc11da69895a680940c1733caabc37be685f5e upstream.

This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159.

When Ath10k is in AP mode and an unassociated STA sends a VHT action frame
(Operating Mode Notification for the NSS change) periodically to AP this causes
ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during
NSS update. Over the time (with a certain client it can happen within 15 mins
when there are over 500 of these VHT action frames) continuous calls of
WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust.

To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS
updates and no need to call ath10k_station_assoc(). So revert the original
commit from 2014 as it's unclear why the change was really needed.
Now the firmware assert doesn't happen anymore.

mac80211_hwsim: fix use-after-free bug in hwsim_exit_net 2018-04-29T09:31:57+00:00 Benjamin Beichler benjamin.beichler@uni-rostock.de 2018-03-07T17:11:07+00:00 21670a464c6b05d92d24e64332e4c57b984d8701 commit 8cfd36a0b53aeb4ec21d81eb79706697b84dfc3d upstream. When destroying a net namespace, all hwsim interfaces, which are not created in default namespace are deleted. But the async deletion of the interfaces could last longer than the actual destruction of the namespace, which results to an use after free bug. Therefore use synchronous deletion in this case.
