2022-03-30udp: fix inner packet checksum calculation in udp-encapMauro Sardara1-4/+9
When computing the inner packet checksum, the code wrongly assumes that the IP version of the inner packet is the same of the outer one. On the contrary, it is perfectly possible to encapsulate v6 packets into v4 and viceversa, so we need to check the IP format of the inner header before calling vnet_calc_checksums_inline.

2021-06-03fib: fix flags updates when adding routes with a udp encap pathArthur de Kerhor1-5/+5
When adding a route via a udp encap instance, FIB_ENTRY_FLAG_IMPORT should not be set. In particular, fib_route_attached_cross_table should always return false for such paths. Modified test_udp_encap to leverage the bug that needed to be fixed. Type: fix Signed-off-by: Arthur de Kerhor <arthurdekerhor@gmail.com> Change-Id: Iaa9489e96d1cff09751f92c62caf7999d924fd7f

2021-02-11tests: tag the tests that do not work with multi-worker configurationAndrew Yourtchenko1-0/+3
If the multi-worker default VPP configuration is triggered by setting VPP_WORKER_CONFIG="workers 2", some of the tests fail for various reasons. It's a substantial number, so this change marks all of the testsets that have this issue, such that they can be addressed later independently.

2019-06-18fib: fib api updatesNeale Ranns1-30/+35
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>

change the ADD api so that is returns the 'ID' that can be used by the client to read the stats from the stats segment and to delete the object.

2017-11-07UDP Encapsulation.Neale Ranns1-0/+235
A UDP-encap object that particiapates in the FIB graph and contributes DPO to teh output chain. It thereofre resembles a tunnel but without the interface. FIB paths (and henace routes) can then be created to egress through the UDP-encap. Said routes can have MPLS labels, hence this also allows MPLSoUPD. Encap is uni-directional. For decap, one still registers with the UDP port dispatcher. Change-Id: I23bd345523b20789a1de1b02022ea1148ca50797 Signed-off-by: Neale Ranns <nranns@cisco.com>
