      mlxsw: spectrum_router: Simplify VRF enslavement · b1e45526
      Ido Schimmel 提交于
      When a netdev is enslaved to a VRF master, its router interface (RIF)
      needs to be destroyed (if exists) and a new one created using the
      corresponding virtual router (VR).
      
      >From the driver's perspective, the above is equivalent to an inetaddr
      event sent for this netdev. Therefore, when a port netdev (or its
      uppers) are enslaved to a VRF master, call the same function that
      would've been called had a NETDEV_UP was sent for this netdev in the
      inetaddr notification chain.
      
      This patch also fixes a bug when a LAG netdev with an existing RIF is
      enslaved to a VRF. Before this patch, each LAG port would drop the
      reference on the RIF, but would re-join the same one (in the wrong VR)
      soon after. With this patch, the corresponding RIF is first destroyed
      and a new one is created using the correct VR.

      Or says:
      ================
      mlx5 neigh update
      
      This series (whose code name is 'neigh update') from Hadar, enhances the
      mlx5 TC IP tunnel offloads to deal with changes to tunnel destination
      neighbours used in offloaded flows which involved encapsulation.
      
      In order to keep track on the validity state of such neighbours, we register
      a netevent notifier callback and act on NEIGH_UPDATE events: if a neighbour
      becomes valid, offload the related flows to HW (the other way around when
      neigh becomes invalid) and similarly when a neigh mac addresses changes.
      
      Since this traffic is offloaded from the host OS, the neighbour for the IP
      tunnel destination can mistakenly become STALE and deleted by the kernel
      since its 'used' value wasn't changed. To address that, we proactively
      update the neighbour 'used' value every DELAY_PROBE_TIME seconds, using
      time stamps generated by the existing driver code for HW flow counters.
      We use the DELAY_PROBE_TIME_UPDATE event to adjust the frequency of the updates.
      
      Prior to the core of the series, there's a patch from Saeed that introduces an
      extendable vport representor implementation scheme. It provides a separation
      between the eswitch to the netdev related aspects of the representors.
      
      We would like to thank Ido Schimmel and Ilya Lesokhin for their coaching && advice
      through the long design and review cycles while we struggled to understand and
      (hopefully correctly) implement the locking around the different driver flows(..) .
      
      - Or.
      =================
      
      Misc Updates:
      
      From Tariq:
      Some small performance and trivial code optimization for mlx5 netdev driver
      - Optimize poll ICOSQ completion queue
      - Use prefetchw when a write is to follow
      - Use u8 as ownership type in mlx5e_get_cqe()
      
      From Eran:
      - Disable LRO by default on specific setups
      
      From Eli:
      - Small cleanup for E-Switch to avoid redundant allocation

      bpf: enhance verifier to understand stack pointer arithmetic · 332270fd
      Yonghong Song 提交于
      llvm 4.0 and above generates the code like below:
      ....
      440: (b7) r1 = 15
      441: (05) goto pc+73
      515: (79) r6 = *(u64 *)(r10 -152)
      516: (bf) r7 = r10
      517: (07) r7 += -112
      518: (bf) r2 = r7
      519: (0f) r2 += r1
      520: (71) r1 = *(u8 *)(r8 +0)
      521: (73) *(u8 *)(r2 +45) = r1
      ....
      and the verifier complains "R2 invalid mem access 'inv'" for insn #521.
      This is because verifier marks register r2 as unknown value after #519
      where r2 is a stack pointer and r1 holds a constant value.
      
      Teach verifier to recognize "stack_ptr + imm" and
      "stack_ptr + reg with const val" as valid stack_ptr with new offset.

      ====================
      Netfilter/IPVS updates for net-next
      
      The following patchset contains Netfilter updates for your net-next
      tree. A large bunch of code cleanups, simplify the conntrack extension
      codebase, get rid of the fake conntrack object, speed up netns by
      selective synchronize_net() calls. More specifically, they are:
      
      1) Check for ct->status bit instead of using nfct_nat() from IPVS and
         Netfilter codebase, patch from Florian Westphal.
      
      2) Use kcalloc() wherever possible in the IPVS code, from Varsha Rao.
      
      3) Simplify FTP IPVS helper module registration path, from Arushi Singhal.
      
      4) Introduce nft_is_base_chain() helper function.
      
      5) Enforce expectation limit from userspace conntrack helper,
         from Gao Feng.
      
      6) Add nf_ct_remove_expect() helper function, from Gao Feng.
      
      7) NAT mangle helper function return boolean, from Gao Feng.
      
      8) ctnetlink_alloc_expect() should only work for conntrack with
         helpers, from Gao Feng.
      
      9) Add nfnl_msg_type() helper function to nfnetlink to build the
         netlink message type.
      
      10) Get rid of unnecessary cast on void, from simran singhal.
      
      11) Use seq_puts()/seq_putc() instead of seq_printf() where possible,
          also from simran singhal.
      
      12) Use list_prev_entry() from nf_tables, from simran signhal.
      
      13) Remove unnecessary & on pointer function in the Netfilter and IPVS
          code.
      
      14) Remove obsolete comment on set of rules per CPU in ip6_tables,
          no longer true. From Arushi Singhal.
      
      15) Remove duplicated nf_conntrack_l4proto_udplite4, from Gao Feng.
      
      16) Remove unnecessary nested rcu_read_lock() in
          __nf_nat_decode_session(). Code running from hooks are already
          guaranteed to run under RCU read side.
      
      17) Remove deadcode in nf_tables_getobj(), from Aaron Conole.
      
      18) Remove double assignment in nf_ct_l4proto_pernet_unregister_one(),
          also from Aaron.
      
      19) Get rid of unsed __ip_set_get_netlink(), from Aaron Conole.
      
      20) Don't propagate NF_DROP error to userspace via ctnetlink in
          __nf_nat_alloc_null_binding() function, from Gao Feng.
      
      21) Revisit nf_ct_deliver_cached_events() to remove unnecessary checks,
          from Gao Feng.
      
      22) Kill the fake untracked conntrack objects, use ctinfo instead to
          annotate a conntrack object is untracked, from Florian Westphal.
      
      23) Remove nf_ct_is_untracked(), now obsolete since we have no
          conntrack template anymore, from Florian.
      
      24) Add event mask support to nft_ct, also from Florian.
      
      25) Move nf_conn_help structure to
          include/net/netfilter/nf_conntrack_helper.h.
      
      26) Add a fixed 32 bytes scratchpad area for conntrack helpers.
          Thus, we don't deal with variable conntrack extensions anymore.
          Make sure userspace conntrack helper doesn't go over that size.
          Remove variable size ct extension infrastructure now this code
          got no more clients. From Florian Westphal.
      
      27) Restore offset and length of nf_ct_ext structure to 8 bytes now
          that wraparound is not possible any longer, also from Florian.
      
      28) Allow to get rid of unassured flows under stress in conntrack,
          this applies to DCCP, SCTP and TCP protocols, from Florian.
      
      29) Shrink size of nf_conntrack_ecache structure, from Florian.
      
      30) Use TCP_MAX_WSCALE instead of hardcoded 14 in TCP tracker,
          from Gao Feng.
      
      31) Register SYNPROXY hooks on demand, from Florian Westphal.
      
      32) Use pernet hook whenever possible, instead of global hook
          registration, from Florian Westphal.
      
      33) Pass hook structure to ebt_register_table() to consolidate some
          infrastructure code, from Florian Westphal.
      
      34) Use consume_skb() and return NF_STOLEN, instead of NF_DROP in the
          SYNPROXY code, to make sure device stats are not fooled, patch
          from Gao Feng.
      
      35) Remove NF_CT_EXT_F_PREALLOC this kills quite some code that we
          don't need anymore if we just select a fixed size instead of
          expensive runtime time calculation of this. From Florian.
      
      36) Constify nf_ct_extend_register() and nf_ct_extend_unregister(),
          from Florian.
      
      37) Simplify nf_ct_ext_add(), this kills nf_ct_ext_create(), from
          Florian.
      
      38) Attach NAT extension on-demand from masquerade and pptp helper
          path, from Florian.
      
      39) Get rid of useless ip_vs_set_state_timeout(), from Aaron Conole.
      
      40) Speed up netns by selective calls of synchronize_net(), from
          Florian Westphal.
      
      41) Silence stack size warning gcc in 32-bit arch in snmp helper,
          from Florian.
      
      42) Inconditionally call nf_ct_ext_destroy(), even if we have no
          extensions, to deal with the NF_NAT_MANIP_SRC case. Patch from
          Liping Zhang.
