2018-06-29ila: Fix use of rhashtable walk in ila_xlat.cTom Herbert
Perform better EAGAIN handling, handle case where ila_dump_info fails and we missed objects in the dump, and add a skip index to skip over ila entires in a list on a rhashtable node that have already been visited (by a previous call to ila_nl_dump).

2018-06-28Merge branch 'net-preserve-sock-reference-when-scrubbing-the-skb'David S. Miller
Flavio Leitner says: ==================== net: preserve sock reference when scrubbing the skb. The sock reference is lost when scrubbing the packet and that breaks TSQ (TCP Small Queues) and XPS (Transmit Packet Steering) causing performance impacts of about 50% in a single TCP stream when crossing network namespaces. XPS breaks because the queue mapping stored in the socket is not available, so another random queue might be selected when the stack needs to transmit something like a TCP ACK, or TCP Retransmissions. That causes packet re-ordering and/or performance issues. TSQ breaks because it orphans the packet while it is still in the host, so packets are queued contributing to the buffer bloat problem. Preserving the sock reference fixes both issues. The socket is orphaned anyways in the receiving path before any relevant action, but the transmit side needs some extra checking included in the first patch. The first patch will update netfilter to check if the socket netns is local before use it. The second patch removes the skb_orphan() from the skb_scrub_packet() and improve the documentation. ChangeLog: - split into two (Eric) - addressed Paolo's offline feedback to swap the checks in xt_socket.c to preserve original behavior. - improved ip-sysctl.txt (reported by Cong) ==================== Signed-off-by: David S.

2018-06-28netem: slotting with non-uniform distributionYousuk Seung
Extend slotting with support for non-uniform distributions. This is similar to netem's non-uniform distribution delay feature. Commit f043efeae2f1 ("netem: support delivering packets in delayed time slots") added the slotting feature to approximate the behaviors of media with packet aggregation but only supported a uniform distribution for delays between transmission attempts. Tests with TCP BBR with emulated wifi links with non-uniform distributions produced more useful results. Syntax: slot dist DISTRIBUTION DELAY JITTER [packets MAX_PACKETS] \ [bytes MAX_BYTES] The syntax and use of the distribution table is the same as in the non-uniform distribution delay feature. A file DISTRIBUTION must be present in TC_LIB_DIR (e.g. /usr/lib/tc) containing numbers scaled by NETEM_DIST_SCALE. A random value x is selected from the table and it takes DELAY + ( x * JITTER ) as delay. Correlation between values is not supported. Examples: Normal distribution delay with mean = 800us and stdev = 100us. > tc qdisc add dev eth0 root netem slot dist normal 800us 100us Optionally set the max slot size in bytes and/or packets. > tc qdisc add dev eth0 root netem slot dist normal 800us 100us \ bytes 64k packets 42 Signed-off-by: Yousuk Seung <ysseung@google.com> Acked-by: Eric Dumazet <edumazet@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

2018-06-27selftests: forwarding: lib: Extract interface-init functionsPetr Machata
The function simple_if_init() does two things: it creates a VRF, then moves an interface into this VRF and configures addresses. The latter comes in handy when adding more interfaces into a VRF later on. The situation is similar for simple_if_fini(). Therefore split the interface remastering and address de/initialization logic to a new pair of helpers __simple_if_init() / __simple_if_fini(), and defer to these helpers from simple_if_init() and simple_if_fini().

2018-06-27selftests: forwarding: tc_rule_stats_get: Parameterize directionPetr Machata
The GRE multipath tests need stats on an egress counter. Change tc_rule_stats_get() to take direction as an optional argument, with default of ingress. Take the opportunity to change line continuation character from | to \. Move the | to the next line, which indent.

2018-06-27selftests: forwarding: multipath_eval(): Improve stylePetr Machata
- Change the indentation of the function body from 7 spaces to one tab. - Move initialization of weights_ratio up so that it can be referenced from the error message about packet difference being zero. - Move |'s consistently to continuation line, which reindent.
