2020-04-15pg: set vnet buffer flags in pg streamsDave Barach7-1/+78
See .../extras/pg/checksum_offload.pg for a nontrivial example, which deliberately sets bogus ip and udp checksums in the generated packets, then fixes the mess with (software emulated) hardware checksum offload. Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100". Packets stuffed into loop1-output have the configured bogus ip and udp checksums. vnet_calc_checksums_inline(...) fixes the checksums, which are correct when packets visit loop1-tx. The packet generator is a dumb robot in this regard. If you ask for a ridiculous flag combination - example: ip4 and ip6 - your mileage may vary.

2020-04-15misc: refactor calc_checksumsDave Barach5-81/+64
Merge two mildly incompatible static inlines, and rename the results vnet_calc_checksums_inline (...). The resulting inline has three additional parameters: int is_ip4, int is_ip6, and int with_gso. All calls manage to pass one or more as compile-time constants, which causes a certain amount of code to disappear in each instantiation.

2020-04-13buffers: configurable buffer fault injectorDave Barach7-0/+108
When configured at compile time via the cmake VPP_BUFFER_FAULT_INJECTOR option, the buffer allocator will appear to fail a certain fraction of the time. By default, the allocator succeeds 80% of the time. Detailed command line configuration options are available, but only when the image has been compiled with cmake option described above: vlib { buffer-alloc-success-rate [0.0 ... 1.0] buffer-alloc-success-seed <nnnn> } Modify vlib_buffer_pool_create(...) so 0 is always an invalid buffer index. Debug images: add checks for bad buffer index enqueues, and also verify that f->n_vectors doesn't accidentally map one or more instances of the frame poison pattern 0xfefefefe.

2020-04-08gbp: More reliable unit-testsNeale Ranns1-16/+16
Type: fix the GBP unit tests would peridocially fail. The reason being that there is dynamic state whose presence nneds to be created, tested and then timeed out. The failures occurded when the timeout occured before the state could be tested. the previous timeout was 2 seconds, this has been doubled, as a result i saw no faliures running continuously for ~16 hours. bumping the timer increasing the test run time from ~40 to ~53 seconds, a small price to pay. in test cases where the state is not timed out i bumped the timer to 60 seconds.
