  "message": "[TCP]: Fix sk_forward_alloc underflow in tcp_sendmsg\n\nI\u0027ve finally found a potential cause of the sk_forward_alloc underflows\nthat people have been reporting sporadically.\n\nWhen tcp_sendmsg tacks on extra bits to an existing TCP_PAGE we don\u0027t\ncheck sk_forward_alloc even though a large amount of time may have\nelapsed since we allocated the page.  In the mean time someone could\u0027ve\ncome along and liberated packets and reclaimed sk_forward_alloc memory.\n\nThis patch makes tcp_sendmsg check sk_forward_alloc every time as we\ndo in do_tcp_sendpages.\n \nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S. Miller \u003cdavem@davemloft.net\u003e\n",
