bd869245a3dc net: core: try to runtime-resume detached device in __dev_open
[Fix]
[Test]
[Where problems could occur] |
[Impact]
The rtnl_lock() has been called in rtnetlink_rcv_msg(), and then in
__dev_open() it calls pm_runtime_resume() to resume devices, and in
some devices' resume function(igb_resum,igc_resume) they calls rtnl_lock()
again. That leads to a recursive lock.
This issue is introduced by below commit since v5.9-rc1
bd869245a3dc net: core: try to runtime-resume detached device in __dev_open
[Fix]
This commit currently is still under discussion fixes the issue.
https://www.spinics.net/lists/netdev/msg736880.html
[Test]
Verified on Dell Precision workstations.
[Where problems could occur]
The patch is pretty straightforward, no problems could occur by this change. |
