2020-02-26api: improve api string safetyJakub Grajciar1-2/+2
- Remove vl_api_from_api_string to prevent use of not nul-terminated strings. - Rename vl_api_from_api_to_vec -> vl_api_from_api_to_new_vec to imply a new vector is created. NOT nul terminated. - Add vl_api_from_api_to_new_c_string. Returns nul terminated string in a new vector. - Add vl_api_c_string_to_api_string. Convert nul terminated string to vl_api_string_t - Add vl_api_vec_to_api_string. Convert NON nul terminated vector to vl_api_string_t Type: fix Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: Iadd59b612c0d960a34ad0dd07a9d17f56435c6ea Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>
2020-02-25vlib: Punt reason allocation listener enable/disable callbackNeale Ranns1-0/+2
Type: improvement allow clients that allocate punt reasons to pass a callback function that is invoked when the first/last client registers to use/listen on that punt reason. This allows the client to perform some necessary configs that might not otherwise be enabled. IPSec uses this callback to register the ESP proto and UDP handling nodes, that would not otherwise be enabled unless a tunnel was present.

2020-02-10ip6: fix l4 checksum with hop-by-hop headerMatthew Smith1-13/+23
L4 checksums for IPv6 should be calculated using a pseudo header that includes the source/destination addresses, payload length, and payload protocol. ip6_tcp_udp_icmp_compute_checksum() was using the payload length and protocol from the IPv6 header. If there is a hop-by-hop header (or any other extension header), the payload length used for the pseudo header should only include the upper layer header and payload and not the extension header bytes. Same deal with the protocol, the upper layer next header value should be used instead of the extension header.

2020-01-11ip: avoid fib lookup for consecutive pkts having same source IPNitin Saxena1-5/+5
Type: fix Fixes: be2286b0 This patch does following: - If terminating frame has consecutive packets with same source IP, this patch avoids fib lookup for those packets in ip4-local node. This drops cycle count for ip4-local node on both ARM and x86. It being done by enabling dead code in else {} case of ip4_local_check_src_x2() and ip4_local_check_src() functions. - In case all packets in terminating frame have unique source IP (e.g: incrementing), ip4-local is costlier by 2 cycles (broadwell) Change-Id: I472ddc324716cec8bfe601568b8aeb7565f97ab3 Signed-off-by: Nitin Saxena <nsaxena@marvell.com>

2019-11-26fib: Table ReplaceNeale Ranns2-131/+126
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.

2019-11-10dhcp: ipv6 prefix delegation improvementsDave Barach1-1/+17
Autoconfigure router advertisements for delegated prefixes. Clean up a longstanding issue. If vpp receives a dhcpv6 renew reply, do NOT reset per-delegated-prefix timers. That prevented vpp from sending a solicit to renew the delegation on time. That, in turn caused the RA code to send advertisements with valid_time = preferred_time = 0. That causes almost any downstream client to throw away its delegated address. Miscellaneous changes o src/vnet/ip/ip6_neighbor.c - always memset elements allocated from pools to zero.
