Vakul Garg 4504ab0e6e net/tls: Inform user space about send buffer availability ... A previous fix ("tls: Fix write space handling") assumed that user space application gets informed about the socket send buffer availability when tls_push_sg() gets called. Inside tls_push_sg(), in case do_tcp_sendpages() returns 0, the function returns without calling ctx->sk_write_space. Further, the new function tls_sw_write_space() did not invoke ctx->sk_write_space. This leads to situation that user space application encounters a lockup always waiting for socket send buffer to become available. Rather than call ctx->sk_write_space from tls_push_sg(), it should be called from tls_write_space. So whenever tcp stack invokes sk->sk_write_space after freeing socket send buffer, we always declare the same to user space by the way of invoking ctx->sk_write_space.
