      sctp: Fix mangled IPv4 addresses on a IPv6 listening socket · 9302d7bb
      Jason Gunthorpe authored
      sctp_v4_map_v6 was subtly writing and reading from members
      of a union in a way the clobbered data it needed to read before
      it read it.
      Zeroing the v6 flowinfo overwrites the v4 sin_addr with 0, meaning
      that every place that calls sctp_v4_map_v6 gets ::ffff: as the
      Reorder things to guarantee correct behaviour no matter what the
      union layout is.
      This impacts user space clients that open an IPv6 SCTP socket and
      receive IPv4 connections. Prior to 299ee user space would see a
      sockaddr with AF_INET and a correct address, after 299ee the sockaddr
      is AF_INET6, but the address is wrong.

      net_sched: invoke ->attach() after setting dev->qdisc · 86e363dc
      WANG Cong authored
      For mq qdisc, we add per tx queue qdisc to root qdisc
      for display purpose, however, that happens too early,
      before the new dev->qdisc is finally set, this causes
      q->list points to an old root qdisc which is going to be
      freed right before assigning with a new one.
      Fix this by moving ->attach() after setting dev->qdisc.
      For the record, this fixes the following crash:

      xen-netfront: properly destroy queues when removing device · ad068118
      David Vrabel authored
      xennet_remove() freed the queues before freeing the netdevice which
      results in a use-after-free when free_netdev() tries to delete the
      napi instances that have already been freed.
      Fix this by fully destroy the queues (which includes deleting the napi
      instances) before freeing the netdevice.

      mlx4_core: Fix fallback from MSI-X to INTx · f4ecf29f

      The test in mlx4_load_one() to remove MLX4_FLAG_MSI_X expects mlx4_NOP() to
      fail with -EBUSY. It is also necessary to avoid the reset since the device
      is not fully reinitialized before calling mlx4_start_hca() a second time.

      This bug has been there since day 1; addresses in the top guest physical
      page weren't considered valid.  You could map that page (the check in
      check_gpte() is correct), but if a guest tried to put a pagetable there
      we'd check that address manually when walking it, and kill the guest.

      Daniel Borkmann authored
      With recent debugging, I noticed that bpf_jit_disasm segfaults when
      there's no debugging output from the JIT compiler to the kernel log.
      Reason is that when regexec(3) doesn't match on anything, start/end
      offsets are not being filled out and contain some uninitialized garbage
      from stack. Thus, we need zero out offsets first.
