2020-06-27udp: align udp_encap_t_ to 2 cachelinesVadym Martsynovskyy1-4/+4
Based on the comments in the struct, udp_encap_t_ is meant to span 2 cachelines. Due to the 64 bit alignment of dpo_id_t, the struct spanned 3 cachelines. This caused fetching ue_ip_proto to trigger an additional cache miss. This patch rearranges the ordering of the struct fields so that udp_encap_t_ only spans 2 cachelines as intended. before: (gdb) print (int)&((struct udp_encap_t_*)0)->cacheline1 $8 = 128 after: (gdb) print (int)&((struct udp_encap_t_*)0)->cacheline1 $1 = 64 Type: fix Signed-off-by: Vadym Martsynovskyy <vmartsyn@fb.com> Change-Id: I066c08654d4a8ef3e2d3954e957d4c5d382b209f

2020-06-27l2: performance enhancement in l2inputZhiyong Yang1-80/+69
Short Load/Stores combined with prefetching in the beginning of the loop place too much pressure on AGUs and memory accesses. The patch interleaves load/store operations with computational operations to alleviate the pain point. vlib_get_buffers is also leveraged. Redefine u8 dst_and_src[12] instead of dst[6] and src[6] in struct l2input_trace_t in order to merge two copys into one.

2020-06-16interface: add minimal vpp pkt trace for error-dropDave Barach2-8/+125
Provide a minimal trace [ip4/ip6 src/dst address] for dropped pkts when the user specifies "trace add error-drop XXXX", but does not trace pkts from the original input node. This is a wireshark dissector problem. Packets thrown at error-drop may be well-formed, or not. VPP must not crash, no matter what. The minimal trace capture and decode could be enhanced. Anyone interested in doing that must consider all of the corner-cases involved. This version should be at least somewhat useful. Note that "pcap trace drop ..." - and the packet generator - seem like the right tools to use when researching more complex issues.

Fix and optimize DMAC check in ethernet-input node to utilize NIC or driver which support L3 DMAC-filtering mode so that DMAC check can be bypassed safely for interfaces/sub-interfaces in L3 mode. Checking of interface in L3-DMAC-filtering state to avoid DMAC check require the following: a) Fix interface driver init sequence for devices which supports L3 DMAC-filtering to indicate its capability and initialize interface to L3 DMAC-filtering state. b) Fix ethernet_set_flags() function and its associated callback flags_change() functions registered by various drivers in interface infra to provide proper L3 DMAC filtering status.

2020-05-27bonding: adjust link state based on active slavesMatthew Smith1-3/+20
Type: improvement Bond link state is being maintained inconsistently. It is initially set to up. If the bond interface admin state is set to down, the link state is set to down. If the bond interface admin state is set to up, the link state is only set to up if there are active slave interfaces at that point. If slaves become active at some later time, it does not get updated. Its next chance to be updated is the next time the bond interface is set to admin up. To address this, do not set the link state to up after creating a bond. Adjust the link state as slave interfaces are attached or detached based on whether the bond is getting its first active slave or losing its last one. Unit test added to verify correct maintenance of link state. Change-Id: I31f17321f7f0e727e1ab1e01713423af6566dad9 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2020-05-25api: add new stream message conventionOle Troan1-0/+1
Instead of having to wrap dump/detail calls in control ping, send details messages in between a normal reply / request pair. As expressed in the below service statement. Example: service { rpc map_domains_gets returns map_domains_get_reply stream map_domain_details; }; define map_domains_get { u32 client_index; u32 context; u32 cursor; }; define map_domains_get_reply { u32 context; i32 retval; u32 cursor; }; To avoid blocking the main thread for too long, the replies are now sent in client message queue size chunks. The reply message returns VNET_API_ERROR_EAGAIN when there is more to read. The API handler must also include a "cursor" that is used to the next call to the get function. API handler example: REPLY_AND_DETAILS_MACRO (VL_API_MAP_DOMAINS_GET_REPLY, mm->domains, ({ send_domain_details (cursor, rp, mp->context); })); The macro starts from cursor and iterates through the pool until vl_api_process_may_suspend() returns true or the iteration reaches the end of the list. Client Example: cursor = 0 d = [] while True: rv, details = map_domains_get(cursor=cursor) d += details if rv.retval == 0 or rv.retval != -165: break cursor = rv.cursor or the convenience iterator: for x in vpp.details_iter(vpp.api.map_domains_get): pass or list(details_iter(map_domains_get)) Change-Id: Iad9f6b41b0ef886adb584c97708dd91cf552749e Type: feature Signed-off-by: Ole Troan <ot@cisco.com>
