Title
net/smc: use smc_lgr_list.lock to protect smc_lgr_list.list iterate in smcr_port_add
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: use smc_lgr_list.lock to protect smc_lgr_list.list iterate in smcr_port_add
While doing smcr_port_add, there maybe linkgroup add into or delete
from smc_lgr_list.list at the same time, which may result kernel crash.
So, use smc_lgr_list.lock to protect smc_lgr_list.list iterate in
smcr_port_add.
The crash calltrace show below:
