These macros are actually printk and pr_cont uses with a flag. Add a new BUGLVL_TEST macro which is just the "should use" test and not an odd "if (<foo>)" macro to simplify uses in a new patch. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree in this 4.4 development cycle, they are: 1) Schedule ICMP traffic to IPVS instances, this introduces a new schedule_icmp proc knob to enable/disable it. By default is off to retain the old behaviour. Patchset from Alex Gartrell. I'm also including what Alex originally said for the record: "The configuration of ipvs at Facebook is relatively straightforward. All ipvs instances bgp advertise a set of VIPs and the network prefers the nearest one or uses ECMP in the event of a tie. For the uninitiated, ECMP deterministically and statelessly load balances by hashing the packet (usually a 5-tuple of protocol, saddr, daddr, sport, and dport) and using that number as an index (basic hash table type logic). The problem is that ICMP packets (which contain really important information like whether or not an MTU has been exceeded) will get a different hash value and may end up at a different ipvs instance. With no information about where to route these packets, they are dropped, creating ICMP black holes and breaking Path MTU discovery. Suddenly, my mom's pictures can't load and I'm fielding midday calls that I want nothing to do with. To address this, this patch set introduces the ability to schedule icmp packets which is gated by a sysctl net.ipv4.vs.schedule_icmp. If set to 0, the old behavior is maintained -- otherwise ICMP packets are scheduled." 2) Add another proc entry to ignore tunneled packets to avoid routing loops from IPVS, also from Alex. 3) Fifteen patches from Eric Biederman to: * Stop passing nf_hook_ops as parameter to the hook and use the state hook object instead all around the netfilter code, so only the private data pointer is passed to the registered hook function. * Now that we've got state->net, propagate the netns pointer to netfilter hook clients to avoid its computation over and over again. A good example of how this has been simplified is the former TEE target (now nf_dup infrastructure) since it has killed the ugly pick_net() function. There's another round of netns updates from Eric Biederman making the line. To avoid the patchbomb again to almost all the networking mailing list (that is 84 patches) I'd suggest we send you a pull request with no patches or let me know if you prefer a better way. ==================== Signed-off-by: -

This patch makes TLP to use 1 sec timer by default when RTT is not available due to SYN/ACK retransmission or SYN cookies. Prior to this change, the lack of RTT prevents TLP so the first data packets sent can only be recovered by fast recovery or RTO. If the fast recovery fails to trigger the RTO is 3 second when SYN/ACK is retransmitted. With this patch we can trigger fast recovery in 1sec instead. Note that we need to check Fast Open more properly. A Fast Open connection could be (accepted then) closed before it receives the final ACK of 3WHS so the state is FIN_WAIT_1. Without the new check, TLP will retransmit FIN instead of SYN/ACK. Signed-off-by:

Currently SYN/ACK RTT is measured in jiffies. For LAN the SYN/ACK RTT is often measured as 0ms or sometimes 1ms, which would affect RTT estimation and min RTT samping used by some congestion control. This patch improves SYN/ACK RTT to be usec resolution if platform supports it. While the timestamping of SYN/ACK is done in request sock, the RTT measurement is carefully arranged to avoid storing another u64 timestamp in tcp_sock. For regular handshake w/o SYNACK retransmission, the RTT is sampled right after the child socket is created and right before the request sock is released (tcp_check_req() in tcp_minisocks.c) For Fast Open the child socket is already created when SYN/ACK was sent, the RTT is sampled in tcp_rcv_state_process() after processing the final ACK an right before the request socket is released. If the SYN/ACK was retransmistted or SYN-cookie was used, we rely on TCP timestamps to measure the RTT. The sample is taken at the same place in tcp_rcv_state_process() after the timestamp values are validated in tcp_validate_incoming(). Note that we do not store TS echo value in request_sock for SYN-cookies, because the value is already stored in tp->rx_opt used by tcp_ack_update_rtt(). One side benefit is that the RTT measurement now happens before initializing congestion control (of the passive side). Therefore the congestion control can use the SYN/ACK RTT. Signed-off-by:

Ursula Braun says: ==================== s390: qeth and iucv patches here is version 2 of some s390 related qeth patches for net-next. The patch by Thomas Richter adds a new feature to the qeth layer2 code; the remaining patches are minor improvements. Version 2 of patch 4 uses the desired indentation in function declarations and definitions spanning multiple lines in almost all cases. Thomas run into a conflict with the maximum number of columns once. Thus you will still see one function definition using an earlier column before the opening paranthesis. ==================== Signed-off-by: -

The iucv code uses arrays as arguments. Even though this does not really cause a problem, it could be misleading, since the compiler turns array arguments into just a pointer argument. To be more precise this patch changes the array arguments into pointers. Signed-off-by:

Checksum offloading for send and receive is already supported for layer 3 (IP layer). This patch adds support for RX and TX hardware checksum offloading for layer 2 (MAC layer). The hardware calculates the checksum for IP UDP and TCP packets. This patch moves the hardware checksum offloading setup to the set of common functions in qeth_core_main.c. Layer 2 and layer 3 now simply call the same common functions. Also note that TX checksum offloading is always enabled. The device driver relies on the TCP/IP stack to make use of this feature.
