2022-12-07classify: increase metadata from 16- to 32-bitsBenoît Ganne2-9/+11
The metadata in classifier entries is used to index a fib or a dpo in the acl nodes which can exceeds UINT16_MAX in large configurations. To maintain entries size and alignment, decrease next_index from 32- to 16-bits: next_index should not exceed 16-bits in VPP, as it is already shown by vlib_buffer_enqueue_to_next() or dpo_id_t.dpoi_next_node.

Fast path spd was explicitely storing array of policy id vectors. This information was redundand, as this inofrmation is already stored in bihash table. This additional array was affecting performance when adding and removing fast path policies.

2022-11-28udp: preallocate ports sparse vec mapFlorin Coras1-2/+80
Not ideal. The sparse vector used to map ports to next nodes assumes only a few ports are ever used. When udp transport is enabled this does not hold and, to make matters worse, ports are consumed in a random order. This can lead to a lot of slow updates to internal data structures which in turn can slow udp connection allocations until all ports are eventually consumed. Consequently, reallocate sparse vector, preallocate all ports and have them point to UDP_NO_NODE_SET. We could consider switching the sparse vector to a preallocated vector but that would increase memory consumption for vpp deployments that do not rely on host stack. For reference, populating one of the v4 or v6 sparse vectors in reverse order takes about 9.8s on a skylake cpu.

2022-11-09ip: fix unformat_ip_address forcing version to IP4 for some IP6 addressesAndrew Yourtchenko1-9/+10
dd2f12ba made use of ip46_address_is_ip4() in order to determine whether the address is ipv4 or ipv6 within unformat_ip_address - however, its logic is correct only for some addresses. e.g. a valid IPv6 address of :: (unspecified) will result in "true" result. This is probably not an issue for most of the cases (the unspecified address is quite rare), however if the unformat_ip_address is used as part of the prefix parsing, the ::/0 is a fairly often utilized construct, which gets parsed as 0.0.0.0 Solution: return the old logic, but use a temporary variable to avoid overwriting the target memory on failure.

2022-11-06ip6-nd: set router flag on NA if appropriateMatthew Smith3-1/+19
Type: fix The router flag on a neighbor advertisement can be used by neighbors to detect that a router has changed to a host (RFC 4861 section 4.4). If a neighbor adds routes after receiving a router advertisement sent by VPP and subsequently receives a neighbor advertisement sent by VPP, it may remove any routes it added based on the RA if the NA does not have the router flag set. It appears that this is how windows behaves. When sending a neighbor advertisement, set the router flag if sending RAs is enabled on the interface.

2022-10-13l2: coverity complains dead codesSteven Luong1-14/+11
Coverity complains dead codes in 2 places due to a recent commit as pointed out in Fixes. The dead codes are if (seed < L2_BD_ID_MAX % 2) is_seed_low = 1; and if (is_seed_low) seed += (2 * (i % 2) - 1) * i; seed can never be less than (L2_BD_ID_MAX % 2). Consequently, is_seed_low is always 0. There is also other problem. The inner loop is iterating only once. The fix is to greatly simplify the code to generate a random bd_id.

2022-10-13session: make session code compile with SESSION_DEBUG enableSteven Luong2-2/+15
Session debug code does not compile anymore due to vlib_mains global variable disappearing over time. Replace it with vlib_get_main_by_index call. Add a cmake variable and pass it from make command line to enable session debug. Notice transport debug is required for session debug. make rebuild VPP_EXTRA_CMAKE_ARGS=-DVPP_TCP_DEBUG_ALWAYS=ON VPP_EXTRA_CMAKE_ARGS+=-DVPP_SESSION_DEBUG=ON Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Ic2e887c6b10b77cbabd56934f4931fcfa04a6751
