Description
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix LGR and link use-after-free issue
We encountered a LGR/link use-after-free issue, which manifested as
the LGR/link refcnt reaching 0 early and entering the clear process,
making resource access unsafe.
refcount_t: addition on 0; use-after-free.
WARNING: CPU: 14 PID: 107447 at lib/refcount.c:25 refcount_warn_saturate+0x9c/0x140

It is caused by repeated release of LGR/link refcnt. One suspect is that
smc_conn_free() is called repeatedly because some smc_conn_free() from
server listening path are not protected by sock lock.
e.g.
Calls under socklock | smc_listen_work
-------------------------------------------------------
lock_sock(sk) | smc_conn_abort
smc_conn_free | \- smc_conn_free
\- smcr_link_put | \- smcr_link_put (duplicated)
release_sock(sk)
So here add sock lock protection in smc_listen_work() path, making it
exclusive with other connection operations.
