2017-10-04VPP-1001 - update AF Packet Driver to for modern kernelsAnton Ivanov4-10/+119
1. Add VNET headers support for checksumming - required to operate correctly on any recent Linux 2. Bypass QDISC on transmit - improves performance by ~ 5%. Enabled only if the macro is detected - apparently not present on archaic distributions. This still does not solve all issues with TSO - it can be fixed only by going to tpacket v3 and dynamic rx ring as well as significant changes in the TX (sendmmsg?).

2017-10-04Add API support to dump IPsec SAsMatthew Smith3-0/+292
Add an API request message type to dump IPsec SAs. Either all IPsec SAs can be dumped or it can be limited to a single SA ID (numeric ID set at creation time - not an index). Add a handler for incoming messages with the new request type. Add an API response message type containing the data for an IPsec SA. Add VAT support for new message type.

2017-09-28tun/tap: Bad packets sent to kernel via tun/tap interfaceSteven2-22/+29
It was observed that under heavy traffic, VPP accidentally sent traffic with the wrong source and destination to the tun/tap interface. Traffic appears to be sent to the wrong direction. This problem is only seen when worker thread is configured. When worker thread is used, TX and RX may reside in different core. Yet both TX and RX threads are sharing the same global variable, namely iovecs without any mutex or memory barrier protection. This creates a race condition when heavy traffic is blasted to VPP, like 1000 pps. We could create a mutex or memory barrier to ensure atomic memory access. But why bother? It is a lot cheaper to just decouple the iovecs such that TX and RX have their own iovecs. Change-Id: I86a5a19bd8de54d54f32e1f0845bae6a81bbf686 Signed-off-by: Steven <sluong@cisco.com>

2017-09-27acl-plugin: take 2 at VPP-991 fix, this time with a test case which verifies it.Andrew Yourtchenko3-3/+42
The replacement of [] with pool_elt_at_index and subsequent fixing it was incorrect - it was equivalent to &[], since it returns a pointer to the element. I've added VPP-993 previously to create a testcase, so this commit partially fulfills that one as well.

For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled. Change-Id: If5fd8ea2d28c54dd28726ac403ad366386ce9651 Signed-off-by: John Lo <loj@cisco.com>
