Move the hash computation located in __skb_get_hash to be a separate function which takes flow_keys as input. This will allow flow hash computation in other contexts where we only have addresses and ports. Signed-off-by: NTom Herbert <therbert@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Florian Fainelli 提交于
Support for Wake-on-LAN using Magic Packet with or without SecureOn password is implemented doing the following: - setting the password to the relevant UniMAC registers - flagging the device as a wakeup source for the system, as well as its Wake-on-LAN interrupt - prepare the hardware for entering WoL mode - enabling the MPD interrupt to wake us The Device Tree binding documentation is also reflected to specify the third optional Wake-on-LAN interrupt line.

Implement the hardware recommended suspend/resume procedure for SYSTEMPORT. We leverage the previous factoring work such that we can logically break all suspend/resume operations into disctint RX and TX code paths. When the system enters S3, we will loose all register contents, so make sure that we correctly re-program all the hardware and software views of the RX & TX rings as well.

Erik Hugne says: ==================== tipc: link state processing improvements Message delivery is separated from the link state processing, and we fix a bug in receive-path triggered acks. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
-
由 Erik Hugne 提交于
Link state acks triggered from the receive path is done before the last received packet have been processed by the link layer. The effect of this is that the last received packet will not be included in the ack. This causes problems if the link window is set to TIPC_MIN_LINK_WIN, where the ack interval will be equal to the link tolerance, and the link enters a stop-and-go behavior. We move the ack logic to after link state processing, just before the packet is delivered to higher layers.

Always store in snt_synack the time at which the server received the first client SYN and attempted to send the first SYNACK. Recent commit aa27fc50 ("tcp: tcp_v[46]_conn_request: fix snt_synack initialization") resolved an inconsistency between IPv4 and IPv6 in the initialization of snt_synack. This commit brings back the idea from 843f4a55 (tcp: use tcp_v4_send_synack on first SYN-ACK), which was going for the original behavior of snt_synack from the commit where it was added in 9ad7c049 ("tcp: RFC2988bis + taking RTT sample from 3WHS for the passive open side") in v3.1. In addition to being simpler (and probably a tiny bit faster), unconditionally storing the time of the first SYNACK attempt has been useful because it allows calculating a performance metric quantifying how long it took to establish a passive TCP connection.

RFC4960, section 8.3 says: On an idle destination address that is allowed to heartbeat, it is recommended that a HEARTBEAT chunk is sent once per RTO of that destination address plus the protocol parameter 'HB.interval', with jittering of +/- 50% of the RTO value, and exponential backoff of the RTO if the previous HEARTBEAT is unanswered. Currently, we calculate jitter via sctp_jitter() function first, and then add its result to the current RTO for the new timeout: TMO = RTO + (RAND() % RTO) - (RTO / 2) `------------------------^-=> sctp_jitter() Instead, we can just simplify all this by directly calculating: TMO = (RTO / 2) + (RAND() % RTO) With the help of prandom_u32_max(), we don't need to open code our own global PRNG, but can instead just make use of the per CPU implementation of prandom with better quality numbers. Also, we can now spare us the conditional for divide by zero check since no div or mod operation needs to be used. Note that prandom_u32_max() won't emit the same result as a mod operation, but we really don't care here as we only want to have a random number scaled into RTO interval. Note, exponential RTO backoff is handeled elsewhere, namely in sctp_do_8_2_transport_strike(). Signed-off-by: NDaniel Borkmann <dborkman@redhat.com> Signed-off-by: NDavid S.

Sathya Perla says: ==================== be2net: patch set v2 change: merged 2 lines into one in patch 4 Patch 1 refactors be_cmd_get_profile_config() routine to reduce code duplication by using the be_cmd_notify_wait() routine, instead of using a separate variant of the code for MBOX and MCCQ. Patch 2 introduces the required FW-cmd code in the PF to query RSS support on a VF. This is in preparation for patch 3. Patch 3 adds support for the PF driver to re-configure the resource distribution in FW based on the number of VFs enabled by the user. When the user is not interested in enabling VFs, all resources of a port are set-aside for the PF. If less than maximum number of VFs are enabled, then each VF gets a better share of the resources and can now enable RSS (if the interface supports it.) Patch 4 is a minor fix to re-enable HW vlan filtering as soon as the number of vlans programmed is within the HW limit. Please consider applying to net-next tree. Thanks! ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

If SR-IOV is enabled in the adapter, the FW distributes queue resources evenly across the PF and it's VFs. If the user is not interested in enabling VFs, the queues set aside for VFs are wasted. This patch adds support for the PF driver to re-configure the resource distribution in FW based on the number of VFs enabled by the user. This also allows for supporting RSS queues on VFs, when less number of VFs are enabled per PF. When maximum number of VFs are enabled, each VF typically gets only one RXQ.
