crypto: chtls - wait for memory sendmsg, sendpage
address suspicious code <gustavo@embeddedor.com>
1210 set_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
1211 }
The issue is that in the code above, set_bit is never reached
due to the 'continue' statement at line 1208.
Also reported by bug report:<dan.carpenter@oracle.com>
1210 set_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Not reachable.
Its required to wait for buffer in the send path and takes care of
unaddress and un-handled SOCK_NOSPACE.
v2: use csk_mem_free where appropriate
proper indent of goto do_nonblock
replace out with do_rm_wq
