Summary
In the Linux kernel, the following vulnerability has been resolved: net: restrict SO_REUSEPORT to inet sockets After blamed commit, crypto sockets could accidentally be destroyed from RCU call back, as spotted by zyzbot [1]. Trying to acquire a mutex in RCU callback is not allowed. Restrict SO_REUSEPORT socket option to inet sockets. v1 of this patch supported TCP, UDP and SCTP sockets, but fcnal-test.sh test needed RAW and ICMP support.
