Revision 1255fcb2a655f05e02f3a74675a6d6525f187afd authored by Ursula Braun on 19 April 2018, 13:56:40 UTC, committed by David S. Miller on 19 April 2018, 20:38:39 UTC 
net/smc: fix shutdown in state SMC_LISTEN
 
Calling shutdown with SHUT_RD and SHUT_RDWR for a listening SMC socket
crashes, because
   commit 127f49705823 ("net/smc: release clcsock from tcp_listen_worker")
releases the internal clcsock in smc_close_active() and sets smc->clcsock
to NULL.
For SHUT_RD the smc_close_active() call is removed.
For SHUT_RDWR the kernel_sock_shutdown() call is omitted, since the
clcsock is already released.

Fixes: 127f49705823 ("net/smc: release clcsock from tcp_listen_worker")
