2021-10-25tcp: fix: TCP timewait port reuse rfc complianceMichal Kalderon2-4/+84
This patch provides a fix for early-kill of timewait sockets that is based on rfc's 1122, 6191. The following commits provided a solution for port re-use. However, they are not fully compliant with rfc 1122 4.2.2.13 ( Closing a connection ) and rfc 6191 (Reducing the TIME-WAIT State Using TCP Timestamps) commit b092b77cf238ba ("tcp: Enable TCP timewait port use") introduced a significant improvement by enabling TCP timewait port re-use. commit ee1cb469b2dd ("tcp: fix port reuse with multiple listeners") fixed usage of the wrong value for connection_index when searching for a listener, by storing the state in tcp.flags. Implementation details: When a SYN is received during time-wait state, the code checks whether all the requirements for accepting the SYN packet are met. If they aren't, the SYN can't be accepted and the packet is dropped, otherwise, connection is deleted and a new connection with same port is opened.

However, since it is just attahcing to the path-list it may not, or indeed cannot, have all the context it needs to successfully handle the walk.

2021-10-21fib: respect mfib entry flags on create with pathsPaul Atkins10-27/+37
When an mfib entry was created with both paths and entry_flags then the entry flags were being ignored. If there are no paths then the flags were passed into mfib_table_entry_update, but in the case where the entry didn't exist and there were paths and flags, the entry was created within mfib_table_entry_paths_update() which used a default of MFIB_ENTRY_FLAG_NONE. Pass the flags through into the mfib_table_entry_paths_update fn. All existing callers other than the create case will now pass in MFIB_ENTRY_FLAG_NONE.

2021-10-21ip: Add ip46-local node for local swif[rx]Nathan Skrzypczak5-44/+132
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.

2021-10-19bfd: fix bfd_key_id updateAlexander Skorichenko1-4/+8
Type: fix Currently, auth activation CLI command "bfd upd session auth activate ... conf-key-id <cki> bfd-key-id <bki>" allows to change both key-ids to new values at once. But if only bfd-key-id should be corrected, e.g. as a result of mistyping, we can't do that in a single operation, and have to deactivate auth first and then reactivate it with a correctly entered pair of ids. Currently, backend's bfd_auth_activate() function returns immediately, with no action, if it finds that submitted conf-key-id matches the current record. No check on bfd-key-id value is made. With this fix, bfd_auth_activate() checks if session's bfd-key-id has to be changed to a new value, and if so, it updates and logs appropriately.

2021-10-13interface: handle error during admin-up correctlyMatthew Smith1-3/+0
Type: fix In vnet_sw_interface_set_flags_helper(), the variable old_flags is set to the original value of vnet_sw_interface_t.flags for an interface. If an error occurs during the process of bringing an interface up, old_flags is used to restore the original value. Before the dev class or hw class admin_up_down_function can be called, but after modifying vnet_sw_interface_t.flags to it's new value, old_flags is set to the value of vnet_sw_interface_t.flags a second time. This discards the original flags that were being preserved. As a result, if an interface is being brought up and the dev class or hw class function fails, at the end VPP believes that interface is up. This can cause a crash if packets are routed through the interface and some RX/TX initialization was not completed because of the error while bringing the interface up.
