2019-06-19interface: Fix the tso segmentationMohsin Kazmi1-10/+9
ASSERT (b[0]->current_length > 0) fails in single loop of function vnet_interface_output_node_inline_gso. Under 'do_segmentation' condition, there are two places in code which execute "continue" in while-loop without incrementing the pointer to next buffer which is wrong behavior. In fact, at one place, current buffer is also freed. In which case, during next iteration buffer ptr still points to free buffer which current length is 0 and triggers the above assert.

2019-06-18fib: fib api updatesNeale Ranns60-3109/+2990
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

Two codes diverged in the packet processor And sorry I could not use them both Long I stood being but one developer And studied one as far as I could To where the code said bitwise OR Then took the other, as just could see, And having perhaps the better bit, Because it followed the RFC And used the cryptic XOR in C, Had run them both a fair bit. And both equally ran that morning With packets dropped and flowing. Oh, I flagged the first for dropping! Yet knowing bug leads to debuging I hoped I'd never be returning. I shall be commiting this with a sigh Somewhere ages and ages hence: Two codes diverged by a bit, and I, I made the packets flow on by, And that has made all the difference.
