2019-09-25api: split api generated filesOle Troan5-77/+33
Split generation of API message enum and the typedefs into separate files, so that the type file can be included from elsewhere. Generate a C file for VPP that contains the API registration, this was previously done via X macros by the C pre- processor. This allows deleting lots of skeleton/copy paste code for each feature. plugins/flowprobe plugins/map examples/sample-plugin vnet/ipip used as Guinea pigs. Generate a C Test file for VAT, that does the same for VAT plugins. Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = "<help text>"; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan <ot@cisco.com>

2019-09-23interface: use the correct condition for checking if the pcap fd is openAndrew Yourtchenko3-3/+3
The 9af7e2e87e used a comparison that fd is >= 0 to check that the pcap needs closing. While the pcap_close() function does reset the file descriptor to -1, the freshly initialized structure has it equal to 0. This causes the VPP to close stdin if the packets are being seen on pg interface without the capture file being opened. This triggers the vpp attempting to read from STDIN (another bug), which results in running out of memory.

2019-09-16api: autogenerate api trace print/endianOle Troan9-10/+156
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on.

2019-09-06bonding: add weight support for active-backup modeSteven Luong4-82/+258
Not all interfaces have the same characteristics within the bonding group. For active-backup mode, we should do our best to select the slave that performs the best as the primary slave. We already did that by preferring the slave that is local numa. Sometimes, this is not enough. For example, when all are local numas, the selection is arbitrary. Some slave interfaces may have higher speed or better qos than the others. But this is hard to infer. One rule does not fit all. So we let the operator to optionally specify the weight for each slave interface. Our primary slave selection rule is now 1. biggest weight 2. is local numa 3. current primary slave (to avoid churn) 4. lowest sw_if_index (for deterministic behavior) This selection rule only applies to active-backup mode which only one slave is used for forwarding traffic until it becomes unreachable. At that time, the next "best" slave candidate is automatically promoted. The slaves are sorted according to the preference rule when they are up. So there is no need to find the next best candidate when the primary slave goes down. Another good thing about this rule is when the down slave comes back up, it is selected as the primary slave again unless there is indeed a "better" slave than this down slave that were added during that period. To set the weight for the slave interface, do this after the interface is enslaved set interface bond <interface-name> weight <value> Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I59ced6d20ce1dec532e667dbe1afd1b4243e04f9
