- Summary
- net: drv: netdevsim: don't napi_complete() from netpoll
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: drv: netdevsim: don't napi_complete() from netpoll
netdevsim supports netpoll. Make sure we don't call napicomplete() from it, since it may not be scheduled. Breno reports hitting a warning in napicomplete_done():
WARNING: CPU: 14 PID: 104 at net/core/dev.c:6592 napicompletedone+0x2cc/0x560 _napipoll+0x2d8/0x3a0 handle_softirqs+0x1fe/0x710
This is presumably after netpoll stole the SCHED bit prematurely.
