2022-03-25fib: fix ip6-ll fib selection for non-ethernet interfacesVladislav Grishenko1-0/+20
Fixes case when packet to link-local address is received over gre/mpls or other non-ethernet interface and ip6-ll fib for it is undefined. If by a chance ip6-ll fib index is valid, packet will be passed to some ip6 fib with possibilities to be sent out over unrelated interface or be looped again into ip6-link-local dpo till oom and crash.

2021-10-21ip: Add ip46-local node for local swif[rx]Nathan Skrzypczak1-8/+6
Type: improvement This adds a new ip[46]-receive node, sibling of ip[46]-local. Its goal is to set vnet_buffer (b)->ip.rx_sw_if_index to the sw_if_index of the local interface. In dependant nodes further down the line (e.g. hoststack) we then set sw_if_idx[rx] to this value. So that we know which local interface did receive the packet. The TCP issue this fixes is that : On accepts, we were setting tc->sw_if_index to the source sw_if_index. We should use the dest sw_if_index, so that packets coming back on this connection have the right source sw_if_index. And also setting it in the tx-ed packet.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-2/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

Type: feature Support setting the MTU for a peer on an interface. The minimum value of the path and interface MTU is used at forwarding time. the path MTU is specified for a given peer, by address and table-ID. In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.

2019-06-18fib: fib api updatesNeale Ranns1-7/+23
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>

2019-05-16init / exit function orderingDave Barach1-4/+9
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2019-02-14Add -fno-common compile optionBenoît Ganne6-4/+8
-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).
