  • The following commit breaks IPv6 TCP transmission for me:
    Commit 75fe83c32248d99e6d5fe64155e519b78bb90481

    ipv6: Preserve ipv6 functionality needed by NET

    This patch fixes the typo "ipv6_offload" which should be
    "ipv6-offload".

    I don't know why not including the offload modules should
    break TCP. Disabling all offload options on the NIC didn't
    help. Outgoing pulseaudio traffic kept stalling.

  • Commit 24cb81a6a (sctp: Push struct net down into all of the
    state machine functions) introduced the net structure into all
    state machine functions, but jsctp_sf_eat_sack was not updated,
    hence when SCTP association probing is enabled in the kernel,
    any simple SCTP client/server program from userspace will panic
    the kernel.

  • Recently I posted commit 3c68198e75 which made selection of the cookie hmac
    algorithm selectable. This is all well and good, but Linus noted that it
    changes the default config:
    http://marc.info/?l=linux-netdev&m=135536629004808&w=2

    I've modified the sctp Kconfig file to reflect the recommended way of making
    this choice, using the thermal driver example specified, and brought the
    defaults back into line with the way they were prior to my origional patch

    Also, on Linus' suggestion, re-adding ability to select default 'none' hmac
    algorithm, so we don't needlessly bloat the kernel by forcing a non-none
    default. This also led me to note that we won't honor the default none
    condition properly because of how sctp_net_init is encoded. Fix that up as
    well.

    Tested by myself (allbeit fairly quickly). All configuration combinations seems
    to work soundly.

    This happens, because sk_clone_lock initializes sk_refcnt to 2, and thus
    a single sock_put() is not enough to free the memory. Additionally, things
    like xfrm, memcg, cookie_values,... may have been initialized.
    We have to free them properly.

    This is fixed by forcing a call to tcp_done(), ending up in
    inet_csk_destroy_sock, doing the final sock_put(). tcp_done() is necessary,
    because it ends up doing all the cleanup on xfrm, memcg, cookie_values,
    xfrm,...

    Before calling tcp_done, we have to set the socket to SOCK_DEAD, to
    force it entering inet_csk_destroy_sock. To avoid the warning in
    inet_csk_destroy_sock, inet_num has to be set to 0.
    As inet_csk_destroy_sock does a dec on orphan_count, we first have to
    increase it.

    Calling tcp_done() allows us to remove the calls to
    tcp_clear_xmit_timer() and tcp_cleanup_congestion_control().

    A similar approach is taken for dccp by calling dccp_done().

    This is in the kernel since 093d282321 (tproxy: fix hash locking issue
    when using port redirection in __inet_inherit_port()), thus since
    version >= 2.6.37.

  • The current multiqueue API is ambigious which may confuse both user and LSM to
    do things correctly:

    - Both TUNSETIFF and TUNSETQUEUE could be used to create the queues of a tuntap
    device.
    - TUNSETQUEUE were used to disable and enable a specific queue of the
    device. But since the state of tuntap were completely removed from the queue,
    it could be used to attach to another device (there's no such kind of
    requirement currently, and it needs new kind of LSM policy.
    - TUNSETQUEUE could be used to attach to a persistent device without any
    queues. This kind of attching bypass the necessary checking during TUNSETIFF
    and may lead unexpected result.

    So this patch tries to make a cleaner and simpler API by:

    - Only allow TUNSETIFF to create queues.
    - TUNSETQUEUE could be only used to disable and enabled the queues of a device,
    and the state of the tuntap device were not detachd from the queues when it
    was disabled, so TUNSETQUEUE could be only used after TUNSETIFF and with the
    same device.

    This is done by introducing a list which keeps track of all queues which were
    disabled. The queue would be moved between this list and tfiles[] array when it
    was enabled/disabled. A pointer of the tun_struct were also introdued to track
    the device it belongs to when it was disabled.

    After the change, the isolation between management and application could be done
    through: TUNSETIFF were only called by management software and TUNSETQUEUE were
    only called by application.For LSM/SELinux, the things left is to do proper
    check during tun_set_queue() if needed.

  • This reverts commit f269ae0469fc882332bdfb5db15d3c1315fe2a10.

    It turns out it causes a very noticeable interactivity regression with
    CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
    terminal window, while scrolling in a browser - the autogrouping means
    that the two end up in separate cgroups, and the browser should be
    smooth as silk despite the high load).

    Says Paul Turner:
    "It seems that the update-throttling on the wake-side is reducing the
    interactive tasks' ability to preempt. While I suspect the right
    longer term answer here is force these updates only in the
    cross-cgroup case; this is less trivial. For this release I believe
    the right answer is either going to be a revert or restore the updates
    on the enqueue-side."

  • Merge emailed autofs cleanup/fix patches from Ian Kent

    * autofs:
    autofs4 - use simple_empty() for empty directory check
    autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount

    Linus Torvalds
     
  • For direct (and offset) mounts, if an automounted mount is manually
    umounted the trigger mount dentry can appear non-empty causing it to
    not trigger mounts. This can also happen if there is a file handle
    leak in a user space automounting application.

    This happens because, when a ioctl control file handle is opened
    on the mount, a cursor dentry is created which causes list_empty()
    to see the dentry as non-empty. Since there is a case where listing
    the directory of these dentrys is needed, the use of dcache_dir_*()
    functions for .open() and .release() is needed.

    Consequently simple_empty() must be used instead of list_empty()
    when checking for an empty directory.

  • The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire
    for autofs rootless multi-mount dentrys to prevent unnecessary calls
    to ->d_automount().

    Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed()
    is always called so the check can be done in ->d_manage() without the
    need to change the flag. This still avoids unnecessary calls to
    ->d_automount(), adds negligible overhead and eliminates a seriously
    ugly check in the expire code.

  • Pull Xen updates from Konrad Rzeszutek Wilk:
    - Add necessary infrastructure to make balloon driver work under ARM.
    - Add /dev/xen/privcmd interfaces to work with ARM and PVH.
    - Improve Xen PCIBack wild-card parsing.
    - Add Xen ACPI PAD (Processor Aggregator) support - so can offline/
    online sockets depending on the power consumption.
    - PVHVM + kexec = use an E820_RESV region for the shared region so we
    don't overwrite said region during kexec reboot.
    - Cleanups, compile fixes.

    Fix up some trivial conflicts due to the balloon driver now working on
    ARM, and there were changes next to the previous work-arounds that are
    now gone.

  • Merge misc VM changes from Andrew Morton:
    "The rest of most-of-MM. The other MM bits await a slab merge.

    This patch includes the addition of a huge zero_page. Not a
    performance boost but it an save large amounts of physical memory in
    some situations.

    Also a bunch of Fujitsu engineers are working on memory hotplug.
    Which, as it turns out, was badly broken. About half of their patches
    are included here; the remainder are 3.8 material."

    However, this merge disables CONFIG_MOVABLE_NODE, which was totally
    broken. We don't add new features with "default y", nor do we add
    Kconfig questions that are incomprehensible to most people without any
    help text. Does the feature even make sense without compaction or
    memory hotplug?
