2021-11-02vppinfra: add CLIB_ASSUME() macroDamjan Marion1-0/+7
This macro privides a way to tell compiler that it is safe to assume that specified expression is true so it can optimize code accordingly. i.e. CLIB_ASSUME (n < 3); while (n) { /* ... */ } Will tell compiler that n is never going to be >= 3 so instead of creating loop it will just unroll loop 2 times.

For example in Wireguard during handshake process this pool can be expand and pointer for these keys in cache can be invalid for workers or can has incorrect value (poison memory).

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.

Type: fix If the walk is triggered when the child is added, then that child is visited in the walk. 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. In the case of MPLS tunnel, it does not have the path extensions ready, and cannot since the path extensions need to resolve on the path-list.

2021-10-21fib: respect mfib entry flags on create with pathsPaul Atkins18-149/+125
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.
