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.

When an UDP application switches from AF_INET to AF_INET6 sockets, we have a small performance degradation for IPv4 communications because of extra cache line misses to access ipv6only information. This can also be noticed for TCP listeners, as ipv6_only_sock() is also used from __inet_lookup_listener()->compute_score() This is magnified when SO_REUSEPORT is used. Move ipv6only into struct sock_common so that it is available at no extra cost in lookups. Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-07-01 This series contains updates to i40e, i40evf, igb and ixgbe. Shannon adds the Base Address High and Low to the admin queue structure to simplify the logic in the configuration routines. Also adds code to clear all queues and interrupts to help clean up after a PXE or other early boot activity. Kevin fixes mask assignment value since -1 cannot be used for unsigned integer types. Mitch fixes an issue where in some circumstances the reply from the PF would come back before we were able to properly modify the admin queue pending and required flags. This would mess up the flags and put the driver in an indeterminate state, so fix this by simply setting the flags before sending the request to the admin queue. Also changes the branding string for i40evf to reduce confusion and to match up with our other marketing materials. Kamil adds a new variable defining admin send queue (ASQ) command write back timeout to allow for dynamic modification of this timeout. Anjali fix a bug in the flow director filter replay logic, so that we call a replay after a sideband reset correctly. Jesse adds code to initialize all members of the context descriptor to prevent possible stale data. Christopher fixes i40e to prevent writing to reserved bits, since the queue index is only 0-127. Jacob removes the unneeded header export.h from the i40e PTP code. Fixes ixgbe PTP code where the PPS signal was not correct, as it generates a one half HZ clock signal, it only generates one level change per second. To generate a full clock, we need two level changes per second. Todd provides a fix for igb to bring up link when the PHY has powered up, which was reported by Jeff Westfahl. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
