      net: sctp: fix ASCONF to allow non SCTP_ADDR_SRC addresses in ipv6 · fecda034
      Daniel Borkmann authored
      Commit 8a07eb0a ("sctp: Add ASCONF operation on the single-homed host")
      implemented possible use of IPv4 addresses with non SCTP_ADDR_SRC state
      as source address when sending ASCONF (ADD) packets, but IPv6 part for
      that was not implemented in 8a07eb0a. Therefore, as this is not restricted
      to IPv4-only, fix this up to allow the same for IPv6 addresses in SCTP.

      ====================
      The following patchset contains three netfilter fixes for your net
      tree, they are:
      
      * A couple of fixes to resolve info leak to userspace due to uninitialized
        memory area in ulogd, from Mathias Krause.
      
      * Fix instruction ordering issues that may lead to the access of
        uninitialized data in x_tables. The problem involves the table update
       (producer) and the main packet matching (consumer) routines. Detected in
        SMP ARMv7, from Will Deacon.

      27) If we are going to mangle a packet in tcp_set_skb_tso_segs() we must

          the driver during TX queueing.  From Eric Dumazet.

      33) Virtual Function fixes in bnx2x driver from Yuval Mintz and Ariel
          Elior.
      
      34) When we removed the explicit neighbour pointer from ipv6 routes a
          slight regression was introduced for users such as IPVS, xt_TEE, and
          raw sockets.  We mix up the users requested destination address with
          the routes assigned nexthop/gateway.  From Julian Anastasov and
          Simon Horman.
      
      35) Fix stack overruns in rt6_probe(), the issue is that can end up

          neighbour discovery messages.  From Hannes Frederic Sowa.

      Revert "bridge: only expire the mdb entry when query is received" · 454594f3
      Linus Lüssing authored
      While this commit was a good attempt to fix issues occuring when no
      multicast querier is present, this commit still has two more issues:
      
      1) There are cases where mdb entries do not expire even if there is a
      querier present. The bridge will unnecessarily continue flooding
      multicast packets on the according ports.
      
      2) Never removing an mdb entry could be exploited for a Denial of
      Service by an attacker on the local link, slowly, but steadily eating up
      all memory.
      
      Actually, this commit became obsolete with
      "bridge: disable snooping if there is no querier" (b00589af)
      which included fixes for a few more cases.
      
      Therefore reverting the following commits (the commit stated in the
      commit message plus three of its follow up fixes):
      
      ====================
      Revert "bridge: update mdb expiration timer upon reports."
      This reverts commit f144febd.
      Revert "bridge: do not call setup_timer() multiple times"
      This reverts commit 1faabf2a.
      Revert "bridge: fix some kernel warning in multicast timer"
      This reverts commit c7e8e8a8.
      Revert "bridge: only expire the mdb entry when query is received"
      This reverts commit 9f00b2e7.

      Mattia Dongili authored
      Do not touch keyboard backlight unless explicitly passed a module
      parameter.  In this way we won't make wrong assumptions about what are
      good default values since they actually are different from model to
      model.
      
      The only side effect is that we won't know what is the current value
      until set via the sysfs attributes.

        Kernel panic - not syncing: Fatal exception in interrupt
      
      This comes about because CPU1 is executing xt_replace_table in response
      to a setsockopt syscall, resulting in:
      
      	ret = xt_jumpstack_alloc(newinfo);
      		--> newinfo->jumpstack = kzalloc(size, GFP_KERNEL);
      
      	[...]
      
      	table->private = newinfo;
      	newinfo->initial_entries = private->initial_entries;
      
      Meanwhile, CPU0 is handling the network receive path and ends up in
      ipt_do_table, resulting in:
      
      	private = table->private;
      
      	[...]
      
      	jumpstack  = (struct ipt_entry **)private->jumpstack[cpu];
      
      On weakly ordered memory architectures, the writes to table->private
      and newinfo->jumpstack from CPU1 can be observed out of order by CPU0.
      Furthermore, on architectures which don't respect ordering of address
      dependencies (i.e. Alpha), the reads from CPU0 can also be re-ordered.
      
      This patch adds an smp_wmb() before the assignment to table->private
      (which is essentially publishing newinfo) to ensure that all writes to
      newinfo will be observed before plugging it into the table structure.
      A dependent-read barrier is also added on the consumer sides, to ensure
      the same ordering requirements are also respected there.

      s390/time: correct use of store clock fast · 8c071b0f
      Martin Schwidefsky authored
      The result of the store-clock-fast (STCKF) instruction is a bit fuzzy.
      It can happen that the value stored on one CPU is smaller than the value
      stored on another CPU, although the order of the stores is the other
      way around. This can cause deltas of get_tod_clock() values to become
      negative when they should not be.
      
      We need to be more careful with store-clock-fast, this patch partially
      reverts git commit e4b7b4238e666682555461fa52eecd74652f36bb "time:
      always use stckf instead of stck if available". The get_tod_clock()
      function now uses the store-clock-extended (STCKE) instruction.
      get_tod_clock_fast() can be used if the fuzziness of store-clock-fast
      is acceptable e.g. for wait loops local to a CPU.

      tcp: initialize passive-side sk_pacing_rate after 3WHS · 02cf4ebd
      Neal Cardwell authored
      For passive TCP connections, upon receiving the ACK that completes the
      3WHS, make sure we set our pacing rate after we get our first RTT
      sample.
      
      On passive TCP connections, when we receive the ACK completing the
      3WHS we do not take an RTT sample in tcp_ack(), but rather in
      tcp_synack_rtt_meas(). So upon receiving the ACK that completes the
      3WHS, tcp_ack() leaves sk_pacing_rate at its initial value.
      
      Originally the initial sk_pacing_rate value was 0, so passive-side
      connections defaulted to sysctl_tcp_min_tso_segs (2 segs) in skbuffs
      made in the first RTT. With a default initial cwnd of 10 packets, this
      happened to be correct for RTTs 5ms or bigger, so it was hard to
      see problems in WAN or emulated WAN testing.
      
      Since 7eec4174 ("pkt_sched: fq: fix non TCP flows pacing"), the
      initial sk_pacing_rate is 0xffffffff. So after that change, passive
      TCP connections were keeping this value (and using large numbers of
      segments per skbuff) until receiving an ACK for data.

      davinci_emac.c: Fix IFF_ALLMULTI setup · d69e0f7e
      Mariusz Ceier authored
      When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't,
      emac_dev_mcast_set should only enable RX of multicasts and reset
      MACHASH registers.
      
      It does this, but afterwards it either sets up multicast MACs
      filtering or disables RX of multicasts and resets MACHASH registers
      again, rendering IFF_ALLMULTI flag useless.
      
      This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and
      disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set.

      ipv6: probe routes asynchronous in rt6_probe · c2f17e82
      Hannes Frederic Sowa authored
      Routes need to be probed asynchronous otherwise the call stack gets
      exhausted when the kernel attemps to deliver another skb inline, like
      e.g. xt_TEE does, and we probe at the same time.
      
      We update neigh->updated still at once, otherwise we would send to
      many probes.

      Merge branch 'rt6i_gateway' · 3a70417c
      David S. Miller authored
      Julian Anastasov says:
      
      ====================
      ipv6: use rt6i_gateway as nexthop
      
      	The following patchset makes sure that rt6i_gateway
      contains valid nexthop information in all cases, so that
      we can use different nexthop for sending.
      
      	The first patch is a simple fix that makes IPVS, TEE,
      RAW(hdrincl) and RTF_DYNAMIC(without RTF_GATEWAY) work as
      before 3.9. There is a single corner case not solved by
      this patch: RAW(hdrincl) or TEE using local address for
      nexthop, a silly feature, I guess. In this case we
      see zeroes in rt6i_gateway because we get route that is not
      cloned. This is solved only with patch 2.
      
      	The second patch is an optimization that makes sure
      all resulting routes have rt6i_gateway filled, so that we
      can avoid the complex ipv6_addr_any() call added to rt6_nexthop()
      by patch 1. And it sets rt6i_gateway for local routes, a case
      not handled by patch 1.
      
      	The third patch uses the new rt6_nexthop() function to fix
      the matching of gateways in the same way as commit bbb5823c
      ("netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper")
      fixes nf_conntrack_h323_main.c for IPv4. Currently, it depends on
      the new definition of rt6_nexthop() in patch 2. Actually, if
      patch 2 is applied, patch 3 becomes a cosmetic change.
      
      	I see the following two alternatives for applying these
      patches:
      
      1. Linger patch 2 in net-next to avoid surprises in the upcoming
      release. In this case patch 3 can be reworked not to depend on
      the new rt6_nexthop() definition in patch 2. I guess this is a
      better option, so that patch 2 can be reviewed and tested for
      longer time.
      
      2. Include all 3 patches in net tree - more risky because this
      is my first attempt to change IPv6.
      
      	Here is the situation as handled by patch 2:
      
      	In IPv6 the resolved routes are always host routes (/128
      with DST_HOST), mostly cloned ones. We allow routes in FIB
      to contain rt6i_gateway with zeroes (eg. for local subnets) but
      on cloning we can fill the rt6i_gateway field in result.
      This works even without this patchset.
      
      	There is a single special case where dst is provided as
      skb_dst directly without a routing call: icmp6_dst_alloc(). It is a
      private dst allocated just for the particular ICMP packet. Patch 2
      fills rt6i_gateway in this case, needed for the new rt6_nexthop()
      simplification.
      
      	The last case is addrconf_dst_alloc(), it can put in
      FIB local/anycast routes when addresses are added. Patch 2
      needs to fill rt6i_gateway in this case because such routes
      are returned without cloning.
