2019-11-27nat: fix dhcp client on outside interface with output featureAlexander Chernavin2-0/+86
When a DHCP client is configured on a NAT outside interface with output feature enabled, DHCP packets will reach the NAT in2out-output node and will be dropped with "out of ports" reason. With this commit, allow locally originated DHCP packets to be sent from a NAT outside interface with output feature enabled.

2019-11-26fib: Table ReplaceNeale Ranns1-13/+16
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.

2019-09-16api: autogenerate api trace print/endianOle Troan1-0/+5
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on. Usage: api trace dump <api-trace-file> For example Change-Id: I4e485680e6dcfce7489299ae6cf31d835071ac40 ---------- trace 48 ----------- vl_api_sw_interface_set_flags_t: _vl_msg_id: 75 client_index: 0 context: 10 sw_if_index: 1 flags: IF_STATUS_API_FLAG_ADMIN_UP ---------- trace 49 ----------- vl_api_sw_interface_add_del_address_t: _vl_msg_id: 88 client_index: 0 context: 11 sw_if_index: 1 is_add: 1 del_all: 0 prefix: 172.16.1.1/24 ---------- trace 51 ----------- vl_api_cli_inband_t: _vl_msg_id: 819 client_index: 0 context: 13 cmd: packet-generator capture pg0 pcap /tmp/vpp-unittest-TestMAP-YhcmDX/pg0_out.pcap disable ---------- trace 58 ----------- vl_api_ip_neighbor_add_del_t: _vl_msg_id: 199 client_index: 0 context: 20 is_add: 1 neighbor: sw_if_index: 2 flags: IP_API_NEIGHBOR_FLAG_NONE mac_address: 0202.0000.ff02 ip_address: fd01:2::2 Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I5556d06008de2762e7c2d35a8b0963ae670b3db1 Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com>

2019-09-03api: enforce vla is last and fixed string typeOle Troan3-123/+42
Enforce that variable length fields are the last element of API messages. Add a 'fixed' version of string type, since dealing with multiple variable length strings turned out too painful for the C language bindings. The string type is now: { string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64] string name[]; // Variable length string with embedded len field (vl_api_string_t) }; The latter notation could be made available to other types as well. e.g. { vl_api_address_t addresses[]; } instead of { u32 n_addr; vl_api_address_t addresses[n_addr]; }; Type: fix Change-Id: I18fa17ef47227633752ab50453e8d20a652a9f9b Signed-off-by: Ole Troan <ot@cisco.com>

2019-04-26nat: fix ED mode unknown proto session managementMatthew Smith3-8/+24
In endpoint dependent mode, when a session at the head of a user LRU is reused, if the IP protocol for that session was unknown (any other than tcp, udp, or icmp), the attempt to delete the session mapping from the in2out bihash was not using the same key that was used when the mapping was added. This would cause the deletion of the mapping to fail. If packets arrive later which match the original session, the search for the session key would succeed when it should have failed and the session, which is now associated with a different pair of endpoints, may end up being updated when it should not be. Update the key generation when reallocating an existing session to do the right thing if the session is for an unknown protocol. Also update format_nat_session() for unknown protocols so that 'vppctl show nat44 session detail' will display the protocol correctly. In endpoint dependent mode, the IP protocol is stored in the port field on a session if the protocol is unknown. The value is stored in host byte order, but the format function was swapping the bytes before writing the protocol.
