  - raw: Fix NULL deref in raw_get_next(). Dae R. Jeong reported a NULL deref in raw_get_next() [0]. It seems     that the repro was running these sequences in parallel so that one thread was iterating on a socket that     was being freed in another netns. unshare(0x40060200) r0 = syz_open_procfs(0x0,     &(0x7f0000002080)='net/raw\x00') socket$inet_icmp_raw(0x2, 0x3, 0x1) pread64(r0, &(0x7f0000000000)=/10,     0xa, 0x10000000007f) After commit 0daf07e52709 (raw: convert raw sockets to RCU), we use RCU and     hlist_nulls_for_each_entry() to iterate over SOCK_RAW sockets. However, we should use spinlock for slow     paths to avoid the NULL deref. Also, SOCK_RAW does not use SLAB_TYPESAFE_BY_RCU, and the slab object is     not reused during iteration in the grace period. In fact, the lockless readers do not check the nulls     marker with get_nulls_value(). So, SOCK_RAW should use hlist instead of hlist_nulls. Instead of adding an     unnecessary barrier by sk_nulls_for_each_rcu(), let's convert hlist_nulls to hlist and use     sk_for_each_rcu() for fast paths and sk_for_each() and spinlock for /proc/net/raw.
