2017-08-04tcp: introduce tcp_rto_delta_us() helper for xmit timer fixNeal Cardwell1-0/+10
Pure refactor. This helper will be required in the xmit timer fix later in the patch series. (Because the TLP logic will want to make this calculation.)

2017-07-30udp6: fix socket leak on early demuxPaolo Abeni1-0/+1
When an early demuxed packet reaches __udp6_lib_lookup_skb(), the sk reference is retrieved and used, but the relevant reference count is leaked and the socket destructor is never called. Beyond leaking the sk memory, if there are pending UDP packets in the receive queue, even the related accounted memory is leaked. In the long run, this will cause persistent forward allocation errors and no UDP skbs (both ipv4 and ipv6) will be able to reach the user-space. Fix this by explicitly accessing the early demux reference before the lookup, and properly decreasing the socket reference count after usage. Also drop the skb_steal_sock() in __udp6_lib_lookup_skb(), and the now obsoleted comment about "socket cache". The newly added code is derived from the current ipv4 code for the similar path. v1 -> v2: fixed the __udp6_lib_rcv() return code for resubmission, as suggested by Eric Reported-by: Sam Edwards <CFSworks@gmail.com> Reported-by: Marc Haber <mh+netdev@zugschlus.de> Fixes: 5425077d73e0 ("net: ipv6: Add early demux handler for UDP unicast") Signed-off-by: Paolo Abeni <pabeni@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2017-07-27sctp: fix the check for _sctp_walk_params and _sctp_walk_errorsXin Long1-2/+2
Commit b1f5bfc27a19 ("sctp: don't dereference ptr before leaving _sctp_walk_{params, errors}()") tried to fix the issue that it may overstep the chunk end for _sctp_walk_{params, errors} with 'chunk_end > offset(length) + sizeof(length)'. But it introduced a side effect: When processing INIT, it verifies the chunks with 'param.v == chunk_end' after iterating all params by sctp_walk_params(). With the check 'chunk_end > offset(length) + sizeof(length)', it would return when the last param is not yet accessed. Because the last param usually is fwdtsn supported param whose size is 4 and 'chunk_end == offset(length) + sizeof(length)' This is a badly issue even causing sctp couldn't process 4-shakes. Client would always get abort when connecting to server, due to the failure of INIT chunk verification on server. The patch is to use 'chunk_end <= offset(length) + sizeof(length)' instead of 'chunk_end < offset(length) + sizeof(length)' for both _sctp_walk_params and _sctp_walk_errors.

2017-07-25udp: preserve head state for IP_CMSG_PASSSECPaolo Abeni1-11/+22
Paul Moore reported a SELinux/IP_PASSSEC regression caused by missing skb->sp at recvmsg() time. We need to preserve the skb head state to process the IP_CMSG_PASSSEC cmsg. With this commit we avoid releasing the skb head state in the BH even if a secpath is attached to the current skb, and stores the skb status (with/without head states) in the scratch area, so that we can access it at skb deallocation time, without incurring in cache-miss penalties. This also avoids misusing the skb CB for ipv6 packets, as introduced by the commit 0ddf3fb2c43d ("udp: preserve skb->dst if required for IP options processing"). Clean a bit the scratch area helpers implementation, to reduce the code differences between 32 and 64 bits build.
