NPC exact match table installs drop on hit rules in NPC mcam for each channel. This rule has broadcast and multicast bits cleared. Exact match bit cleared and channel bits set. If exact match table hit bit is 0, corresponding NPC mcam drop rule will be hit for the packet and will be dropped. Signed-off-by:

CN10KB silicon supports exact match table. Scanning KEX profile should check for exact match feature is enabled and then set profile masks properly. These kex profile masks are required to configure NPC MCAM drop rules. If there is a miss in exact match table, these drop rules will drop those packets. Signed-off-by:

CN10KB silicon has support for exact match table. This table can be used to match maimum 64 bit value of KPU parsed output. Hit/non hit in exact match table can be used as a KEX key to NPC mcam. This patch makes use of Exact match table to increase number of DMAC filters supported. NPC mcam is no more need for each of these DMAC entries as will be populated in Exact match table. This patch implements following 1. Initialization of exact match table only for CN10KB. 2. Add/del/update interface function for exact match table. Signed-off-by:

CN10KB variant of CN10K series of silicons supports a new feature where in a large protocol field (eg 128bit IPv6 DIP) can be condensed into a small hashed 32bit data. This saves a lot of space in MCAM key and allows user to add more protocol fields into the filter. A max of two such protocol data can be hashed. This patch adds support for hashing IPv6 SIP and/or DIP. Signed-off-by:

If we set XFRM security policy by calling setsockopt with option IPV6_XFRM_POLICY, the policy will be stored in 'sock_policy' in 'sock' struct. However tcp_v6_send_response doesn't look up dst_entry with the actual socket but looks up with tcp control socket. This may cause a problem that a RST packet is sent without ESP encryption & peer's TCP socket can't receive it. This patch will make the function look up dest_entry with actual socket, if the socket has XFRM policy(sock_policy), so that the TCP response packet via this function can be encrypted, & aligned on the encrypted TCP socket. Tested: We encountered this problem when a TCP socket which is encrypted in ESP transport mode encryption, receives challenge ACK at SYN_SENT state. After receiving challenge ACK, TCP needs to send RST to establish the socket at next SYN try. But the RST was not encrypted & peer TCP socket still remains on ESTABLISHED state. So we verified this with test step as below. [Test step] 1. Making a TCP state mismatch between client(IDLE) & server(ESTABLISHED). 2. Client tries a new connection on the same TCP ports(src & dst). 3. Server will return challenge ACK instead of SYN,ACK. 4. Client will send RST to server to clear the SOCKET. 5. Client will retransmit SYN to server on the same TCP ports. [Expected result] The TCP connection should be established.

The mentioned test measures the transfer run-time to verify that the user-space program is able to use the full aggregate B/W. Even on (virtual) link-speed-bound tests, debug kernel can slow down the transfer enough to cause sporadic test failures. Instead of unconditionally raising the maximum allowed run-time, tweak when the running kernel is a debug one, and use some simple/ rough heuristic to guess such scenarios. Note: this intentionally avoids looking for /boot/config-<version> as the latter file is not always available in our reference CI environments. Signed-off-by:

sk_skb_cb lives within skb->cb[]. skb->cb[] straddles 2 cache lines, each containing 24B of data.

Previously strp_msg->full_len would live in the first cache line and strp_msg->offset in the second.

This change addresses a comment made earlier [0] about a missing return of an error when __bpf_core_types_match is invoked from bpf_core_composites_match, which could have let to us erroneously ignoring errors. Regarding the typedef name check pointed out in the same context, it is not actually an issue, because callers of the function perform a name check for the root type anyway. To make that more obvious, let's add comments to the function (similar to what we have for bpf_core_types_are_compat, which is called in pretty much the same context).

TCP allocates 'fast clones' skbs for packets in tx queues. Currently, __alloc_skb() initializes the companion fclone field to SKB_FCLONE_CLONE, and leaves other fields untouched. It makes sense to defer this init much later in skb_clone(), because all fclone fields are copied and hot in cpu caches at that time. This removes one cache line miss in __alloc_skb(), cost seen on an host with 256 cpus all competing on memory accesses. Signed-off-by:
