2018-02-01drm/i915/gvt: validate gfn before set shadow page entryHang Yuan
GVT may receive partial write on one guest PTE update. Validate gfn not to translate incomplete gfn. This avoids some unnecessary error messages incurred by the incomplete gfn translating. Also fix the bug that the whole PPGTT shadow page update is aborted on any invalid gfn entry. gfn validation relys on hypervisor's help. Add one MPT module function to provide the function.

2018-02-01openvswitch: Remove padding from packet before L3+ conntrack processingEd Swierk
IPv4 and IPv6 packets may arrive with lower-layer padding that is not included in the L3 length. For example, a short IPv4 packet may have up to 6 bytes of padding following the IP payload when received on an Ethernet device with a minimum packet length of 64 bytes. Higher-layer processing functions in netfilter (e.g. nf_ip_checksum(), and help() in nf_conntrack_ftp) assume skb->len reflects the length of the L3 header and payload, rather than referring back to ip_hdr->tot_len or ipv6_hdr->payload_len, and get confused by lower-layer padding. In the normal IPv4 receive path, ip_rcv() trims the packet to ip_hdr->tot_len before invoking netfilter hooks. In the IPv6 receive path, ip6_rcv() does the same using ipv6_hdr->payload_len. Similarly in the br_netfilter receive path, br_validate_ipv4() and br_validate_ipv6() trim the packet to the L3 length before invoking netfilter hooks. Currently in the OVS conntrack receive path, ovs_ct_execute() pulls the skb to the L3 header but does not trim it to the L3 length before calling nf_conntrack_in(NF_INET_PRE_ROUTING). When nf_conntrack_proto_tcp encounters a packet with lower-layer padding, nf_ip_checksum() fails causing a "nf_ct_tcp: bad TCP checksum" log message. While extra zero bytes don't affect the checksum, the length in the IP pseudoheader does. That length is based on skb->len, and without trimming, it doesn't match the length the sender used when computing the checksum. In ovs_ct_execute(), trim the skb to the L3 length before higher-layer processing.

2018-02-01tcp_bbr: fix pacing_gain to always be unity when using lt_bwNeal Cardwell
This commit fixes the pacing_gain to remain at BBR_UNIT (1.0) when using lt_bw and returning from the PROBE_RTT state to PROBE_BW. Previously, when using lt_bw, upon exiting PROBE_RTT and entering PROBE_BW the bbr_reset_probe_bw_mode() code could sometimes randomly end up with a cycle_idx of 0 and hence have bbr_advance_cycle_phase() set a pacing gain above 1.0. In such cases this would result in a pacing rate that is 1.25x higher than intended, potentially resulting in a high loss rate for a little while until we stop using the lt_bw a bit later. This commit is a stable candidate for kernels back as far as 4.9.

2018-02-01Merge branch 'bnx2x-disable-GSO-on-too-large-packets'David S. Miller
Daniel Axtens says: ==================== bnx2x: disable GSO on too-large packets We observed a case where a packet received on an ibmveth device had a GSO size of around 10kB. This was forwarded by Open vSwitch to a bnx2x device, where it caused a firmware assert. This is described in detail at [0]. Ultimately we want a fix in the core, but that is very tricky to backport. So for now, just stop the bnx2x driver from crashing. When net-next re-opens I will send the fix to the core and a revert for this. v4 changes: - fix compilation error with EXPORTs (patch 1) - only do slow test if gso_size is greater than 9000 bytes (patch 2) Thanks, Daniel [0]: https://patchwork.ozlabs.org/patch/859410/ ==================== Signed-off-by: David S.
