2020-03-16Merge branch 'tcp-fix-stretch-ACK-bugs-in-congestion-control-modules'David S. Miller
Pengcheng Yang says: ==================== tcp: fix stretch ACK bugs in congestion control modules "stretch ACKs" (caused by LRO, GRO, delayed ACKs or middleboxes) can cause serious performance shortfalls in common congestion control algorithms. Neal Cardwell submitted a series of patches starting with commit e73ebb0881ea ("tcp: stretch ACK fixes prep") to handle stretch ACKs and fixed stretch ACK bugs in Reno and CUBIC congestion control algorithms. This patch series continues to fix bic, scalable, veno and yeah congestion control algorithms to handle stretch ACKs.

2020-03-16tcp: fix stretch ACK bugs in YeahPengcheng Yang
Change Yeah to properly handle stretch ACKs in additive increase mode by passing in the count of ACKed packets to tcp_cong_avoid_ai(). In addition, we re-implemented the scalable path using tcp_cong_avoid_ai() and removed the pkts_acked variable. Signed-off-by: Pengcheng Yang <yangpc@wangsu.com> Signed-off-by: David S.

2020-03-16sfc: fix XDP-redirect in this driverJesper Dangaard Brouer
XDP-redirect is broken in this driver sfc. XDP_REDIRECT requires tailroom for skb_shared_info when creating an SKB based on the redirected xdp_frame (both in cpumap and veth). The fix requires some initial explaining. The driver uses RX page-split when possible. It reserves the top 64 bytes in the RX-page for storing dma_addr (struct efx_rx_page_state). It also have the XDP recommended headroom of XDP_PACKET_HEADROOM (256 bytes). As it doesn't reserve any tailroom, it can still fit two standard MTU (1500) frames into one page. The sizeof struct skb_shared_info in 320 bytes. Thus drivers like ixgbe and i40e, reduce their XDP headroom to 192 bytes, which allows them to fit two frames with max 1536 bytes into a 4K page (192+1536+320=2048). The fix is to reduce this drivers headroom to 128 bytes and add the 320 bytes tailroom. This account for reserved top 64 bytes in the page, and still fit two frame in a page for normal MTUs. We must never go below 128 bytes of headroom for XDP, as one cacheline is for xdp_frame area and next cacheline is reserved for metadata area.

2020-03-16remoteproc: clean up notification configAlex Elder
Rearrange the config files for remoteproc and IPA to fix their interdependencies. First, have CONFIG_QCOM_Q6V5_MSS select QCOM_Q6V5_IPA_NOTIFY so the notification code is built regardless of whether IPA needs it. Next, represent QCOM_IPA as being dependent on QCOM_Q6V5_MSS rather than setting its value to match QCOM_Q6V5_COMMON (which is selected by QCOM_Q6V5_MSS). Drop all dependencies from QCOM_Q6V5_IPA_NOTIFY. The notification code will be built whenever QCOM_Q6V5_MSS is set, and it has no other dependencies.

In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming frame can be 0 when XPN cipher suite is used, so fixed the function `macsec_validate_skb` to fail on PN=0 only if XPN is off.

Russell King says: ==================== net: dsa: improve serdes integration Depends on "net: mii clause 37 helpers". Andrew Lunn mentioned that the Serdes PCS found in Marvell DSA switches does not automatically update the switch MACs with the link parameters. Currently, the DSA code implements a work-around for this. This series improves the Serdes integration, making use of the recent phylink changes to support split MAC/PCS setups. One noticable improvement for userspace is that ethtool can now report the link partner's advertisement. This repost has no changes compared to the previous posting; however, the regression Andrew had found which exists even without this patch set has now been fixed by Andrew and merged into the net-next tree. ==================== Signed-off-by: David S.

2020-03-15net: dsa: mv88e6xxx: combine port_set_speed and port_set_duplexRussell King
Setting the speed independently of duplex makes little sense; the two parameters result from negotiation or fixed setup, and may have inter- dependencies. Moreover, they are always controlled via the same register - having them split means we have to read-modify-write this register twice. Combine the two operations into a single port_set_speed_duplex() operation. Not only is this more efficient, it reduces the size of the code as well.

2020-03-15net: dsa: mv88e6xxx: fix Serdes link changesRussell King
phylink_mac_change() is supposed to be called with a 'false' argument if the link has gone down since it was last reported up; this is to ensure that link events along with renegotiation events are always correctly reported to userspace. Read the BMSR once when we have an interrupt, and report the link latched status to phylink via phylink_mac_change(). phylink will deal automatically with re-reading the link state once it has processed the link-down event.
