Andrey Ryabinin fc64869c48 net: sock: move ->sk_shutdown out of bitfields. ... ->sk_shutdown bits share one bitfield with some other bits in sock struct, such as ->sk_no_check_[r,t]x, ->sk_userlocks ... sock_setsockopt() may write to these bits, while holding the socket lock. In case of AF_UNIX sockets, we change ->sk_shutdown bits while holding only unix_state_lock(). So concurrent setsockopt() and shutdown() may lead to corrupting these bits. Fix this by moving ->sk_shutdown bits out of bitfield into a separate byte. This will not change the 'struct sock' size since ->sk_shutdown moved into previously unused 16-bit hole.
