      usbnet: consider device busy at each recieved packet · 8a783354
      Oliver Neukum authored
      usbnet should centrally handle busy reporting in the rx path
      so subdrivers need not worry. This hurts use cases which do
      rx only or predominantly.

      bonding: remove entries for master_ip and vlan_ip and query devices instead · eaddcd76
      Andy Gospodarek authored
      The following patch aimed to resolve an issue where secondary, tertiary,
      etc. addresses added to bond interfaces could overwrite the
      bond->master_ip and vlan_ip values.
      
              commit 917fbdb3
              Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com>
              Date:   Wed Nov 23 23:37:15 2011 +0000
      
                  bonding: only use primary address for ARP
      
      That patch was good because it prevented bonds using ARP monitoring from
      sending frames with an invalid source IP address.  Unfortunately, it
      didn't always work as expected.
      
      When using an ioctl (like ifconfig does) to set the IP address and
      netmask, 2 separate ioctls are actually called to set the IP and netmask
      if the mask chosen doesn't match the standard mask for that class of
      address.  The first ioctl did not have a mask that matched the one in
      the primary address and would still cause the device address to be
      overwritten.  The second ioctl that was called to set the mask would
      then detect as secondary and ignored, but the damage was already done.
      
      This was not an issue when using an application that used netlink
      sockets as the setting of IP and netmask came down at once.  The
      inconsistent behavior between those two interfaces was something that
      needed to be resolved.
      
      While I was thinking about how I wanted to resolve this, Ralf Zeidler
      came with a patch that resolved this on a RHEL kernel by keeping a full
      shadow of the entries in dev->ifa_list for the bonding device and vlan
      devices in the bonding driver.  I didn't like the duplication of the
      list as I want to see the 'bonding' struct and code shrink rather than
      grow, but liked the general idea.
      
      As the Subject indicates this patch drops the master_ip and vlan_ip
      elements from the 'bonding' and 'vlan_entry' structs, respectively.
      This can be done because a device's address-list is now traversed to
      determine the optimal source IP address for ARP requests and for checks
      to see if the bonding device has a particular IP address.  This code
      could have all be contained inside the bonding driver, but it made more
      sense to me to EXPORT and call inet_confirm_addr since it did exactly
      what was needed.
      
      I tested this and a backported patch and everything works as expected.
      Ralf also helped with verification of the backported patch.
      
      Thanks to Ralf for all his help on this.

      netfilter: remove forward module param confusion. · 523f610e
      Rusty Russell authored
      It used to be an int, and it got changed to a bool parameter at least
      7 years ago.  It happens that NF_ACCEPT and NF_DROP are 0 and 1, so
      this works, but it's unclear, and the check that it's in range is not
      required.

      net: fix napi_reuse_skb() skb reserve · 2a2a459e
      Eric Dumazet authored
      napi->skb is allocated in napi_get_frags() using
      netdev_alloc_skb_ip_align(), with a reserve of NET_SKB_PAD +
      NET_IP_ALIGN bytes.
      
      However, when such skb is recycled in napi_reuse_skb(), it ends with a
      reserve of NET_IP_ALIGN which is suboptimal.

      Pull irq_domain support for all architectures from Grant Likely:
       "Generialize powerpc's irq_host as irq_domain
      
        This branch takes the PowerPC irq_host infrastructure (reverse mapping
        from Linux IRQ numbers to hardware irq numbering), generalizes it,
        renames it to irq_domain, and makes it available to all architectures.
      
        Originally the plan has been to create an all-new irq_domain
        implementation which addresses some of the powerpc shortcomings such
        as not handling 1:1 mappings well, but doing that proved to be far
        more difficult and invasive than generalizing the working code and
        refactoring it in-place.  So, this branch rips out the 'new'
        irq_domain and replaces it with the modified powerpc version (in a
        fully bisectable way of course).  It converts all users over to the
        new API and makes irq_domain selectable on any architecture.
      
        No architecture is forced to enable irq_domain, but the infrastructure
        is required for doing OpenFirmware style irq translations.  It will
        even work on SPARC even though SPARC has it's own mechanism for
        translating irqs at boot time.  MIPS, microblaze, embedded x86 and c6x
        are converted too.
      
        The resulting irq_domain code is probably still too verbose and can be
        optimized more, but that can be done incrementally and is a task for
        follow-on patches."

      exit_signal: fix the "parent has changed security domain" logic · b6e238dc
      Oleg Nesterov authored
      exit_notify() changes ->exit_signal if the parent already did exec.
      This doesn't really work, we are not going to send the signal now
      if there is another live thread or the exiting task is traced. The
      parent can exec before the last dies or the tracer detaches.
      
      Move this check into do_notify_parent() which actually sends the
      signal.
      
      The user-visible change is that we do not change ->exit_signal,
      and thus the exiting task is still "clone children" for
      do_wait()->eligible_child(__WCLONE). Hopefully this is fine, the
      current logic is racy anyway.

      exit_signal: simplify the "we have changed execution domain" logic · e6368253
      Oleg Nesterov authored
      exit_notify() checks "tsk->self_exec_id != tsk->parent_exec_id"
      to handle the "we have changed execution domain" case.
      
      We can change do_thread() to always set ->exit_signal = SIGCHLD
      and remove this check to simplify the code.
      
      We could change setup_new_exec() instead, this looks more logical
      because it increments ->self_exec_id. But note that de_thread()
      already resets ->exit_signal if it changes the leader, let's keep
      both changes close to each other.
      
      Note that we change ->exit_signal lockless, this changes the rules.
      Thereafter ->exit_signal is not stable under tasklist but this is
      fine, the only possible change is OLDSIG -> SIGCHLD. This can race
      with eligible_child() but the race is harmless. We can race with
      reparent_leader() which changes our ->exit_signal in parallel, but
      it does the same change to SIGCHLD.
      
      The noticeable user-visible change is that the execing task is not
      "visible" to do_wait()->eligible_child(__WCLONE) right after exec.
      To me this looks more logical, and this is consistent with mt case.

      CLONE_PARENT shouldn't allow to set ->exit_signal · 5f8aadd8
      Oleg Nesterov authored
      The child must not control its ->exit_signal, it is the parent who
      decides which signal the child should use for notification.
      
      This means that CLONE_PARENT should not use "clone_flags & CSIGNAL",
      the forking task is the sibling of the new process and their parent
      doesn't control exit_signal in this case.
      
      This patch uses ->exit_signal of the forking process, but perhaps
      we should simply use SIGCHLD.
      
      We read group_leader->exit_signal lockless, this can race with the
      ORIGINAL_SIGNAL -> SIGCHLD transition, but this is fine.
      
      Potentially this change allows to kill self_exec_id/parent_exec_id.

      Fix pppol2tp getsockname() · bbdb32cb
      Benjamin LaHaise authored
      While testing L2TP functionality, I came across a bug in getsockname().  The
      IP address returned within the pppol2tp_addr's addr memember was not being
      set to the IP  address in use.  This bug is caused by using inet_sk() on the
      wrong socket (the L2TP socket rather than the underlying UDP socket), and was
      likely introduced during the addition of L2TPv3 support.
